- The Automobile Fire Engine
The Automobile Fire Engine can go to the fires very swiftly. Many times the saving of a few minutes by the firemen in reaching a fire means stopping the blaze before it becomes too great. - Kimpton-Brown Tube
Whole Blood Transfusion with Kimpton’s Tube. The principle of this method depends upon the use of paraffin wax as a coating for the vessel into which the blood is drawn, so that clotting is prevented or greatly delayed. The form of the vessel has been modified by different workers, but the essentials are the same in each. One form of the apparatus, known as the Kimpton-Brown tube, is illustrated in the accompanying diagram. It consists of a graduated glass cylinder, of about 700 cc. capacity, the lower end of which is drawn out into a cannula point at an acute angle with the body of the cylinder; the point is of a size convenient for introducing into a vein and its bore large enough to allow of a free flow of blood through it. Near the upper end is a side tube to which a rubber tube can be attached, and an opening at the top is closed by a rubber bung. An ordinary rubber double-bulb bellows is the only other apparatus that is needed. - Drawing Blood for Transfusion
When the donor’s arm has been congested by gripping it above the elbow, or better by the application of a tourniquet drawn to the requisite degree of tightness, a suitable vein, usually the median basilic, is chosen. The area of puncture is washed with ether and a very small quantity, 2 to 3 minims, of 2 per cent. novocain is introduced over the vein with a hypodermic syringe. If a larger quantity is used, the vein may become obscured, but this small amount may be dispersed by a few moments’ pressure with the finger, and is usually enough to anæsthetize the very small area of skin that is to be operated upon. A tiny cut in the skin is then made with the point of a scalpel, and the needle is pushed through into the vein. - Blundell’s Impellor
A more general interest in the subject was revived in England by the work of James Blundell, lecturer on physiology and midwifery at St. Thomas’s and Guy’s Hospitals. He published in 1818 his earliest paper on experimental transfusion with a special form of syringe invented by himself. His first apparatus consisted of a funnel-shaped receptacle for the blood, connected by a two-way tap with a syringe from which the blood was injected through a tube and cannula into the recipient. His experiments were[11] performed upon dogs, and he began by drawing blood from the femoral artery and re-injecting it into the same animal through the femoral vein. He then conducted a long series of investigations into the properties of blood, the effects of its withdrawal, and the resuscitation of an exsanguinated animal. Soon he had opportunities of transfusing patients with human blood, and the results are recorded in his paper of 1824. His apparatus had by then been elaborated, and an engraving of his Impellor, as he termed it, is reproduced here. It consisted as before of a funnel-shaped receptacle for the blood, but the syringe was now incorporated in one side of the funnel, and contained a complicated system of spring valves, which caused the blood to travel along the delivery tube when the piston was pushed down. The Impellor was fixed to the back of a chair in order to give it stability. - Throw to first

A One-hand catch - Wright Brothers first powered airplane
By 1903 the Wright Brothers were ready to build a powered man-carrying flying machine. Their experiments had shown them just how much moving air was necessary to create lift in such a machine. To create the needed thrust, an engine having eight horsepower and weighing not over 200 pounds had to be fitted into the machine. Such an engine was not available, so the Wrights built one in their shop at Dayton, Ohio. They were ready to ship their airplane to Kitty Hawk, N. C., in the fall of 1903. - The Wright Brothers experimental glider
After a year of exhaustive study and experiments with models in their wind tunnel, the Wright Brothers were ready to experiment with a man-carrying glider. With the thoroughness that was typical of every move of the Wrights, the brothers asked the government to let them have information on meteorological conditions all over the country. By studying the weather charts they were able to find a locality where there was a continual flow of wind. This would be nature’s wind tunnel where they could test their glider day after day. Through their study of the charts they found that the wind conditions at Kitty Hawk, on the North Carolina coast, seemed to offer the best possibilities for their glider test. Orville and Wilbur Wright began their experiments with a small man-carrying glider at Kitty Hawk in 1900. From that time until 1903 they made hundreds of successful glider flights and kept accurate records of each flight. They recorded wind velocity, angle of flight, duration of flight, time of day, temperature, humidity, and sky conditions overhead with the typical Wright attention to detail. Each year the Wrights constructed new gliders which embodied principles they had discovered for themselves during their flights at Kitty Hawk. Each glider was larger and had longer and narrower wings than the one before. During the fall of 1902 the brothers recorded nearly a thousand flights in a glider with a wingspan of thirty-two feet. It had a front elevator and a vertical tail which helped to maintain lateral stability. - The Four forces of flight
after testing more than 200 wing designs and plane surfaces in their wind tunnel, the Wright Brothers found out how to figure correctly the amount of curve, or camber, that was essential to weight-carrying wings. They discovered, too, that before man could be flown through the air, he must have his wings attached firmly to a body or platform which was firm and controllable. The Wrights in their earliest experiments had realized that to be practical their machine must be built not only to fly in a straight line, but also in order that it could be steered to the right or to the left. One day, Orville was twisting a cardboard box in his hand when Wilbur noticed it. Immediately he saw the solution to the problem of steering their airplane. The result was a design which changed the lift of either end of the wing by warping its surface. If one end of the wing was warped to give it more lift, the machine would lift on that side and fall off into a turn. Thus the problem of steering was solved by the Wrights - Wright Brothers' Wind tunnel
They found that a slight curve or camber in the wing section would cause the moving air to travel farther over the top of the wing surface than along the under side. This made the air pressure greater under the wing, gave a suction effect above the wing, and caused it to rise, creating lift. They discovered that a wing section of the proper camber would counteract the weight of gravity. Thus, a wing must be so designed that, with a certain amount of air flowing around it, it would lift a certain weight. They also discovered that air flow against any surface attached to the wing would cause a resistance or drag. Hundreds of experiments in their wind tunnel with various types of wing shapes gave the Wrights a series of tables from which to design a wing that would create the lift for a designed weight. - The Regent Canal at Maida Hill

Cutting out the material using a pattern - The clothing worn during the day should be aired at night
Airing clothing The body must be kept clean; and clothing worn next to it should also be kept clean at night as well as during the day. Who can remember how many pints of water the normal body gives off each day? It loses about three pints in 24 hours. Can you recall what becomes of this waste? Yes, some is evaporated, but some is collected by our clothes; that is why they are soiled as they collect the perspiration and excretions, although often they do not look soiled. The day garments should be hung up at night in a place where they will air and dry out by morning. - Lady doing needlework

Do you understand what appropriateness means? It means wearing the suitable kind of clothing for every occasion. It is our duty to be as well dressed as possible, for our friends' sakes as well as for our own; but a well-dressed girl is never conspicuous. Clothes which would be appropriate in a large city for a reception might be very inappropriate in a small town. Our daily clothes should be adapted to our uses, whether in country or city. Would you wear your party dress for gardening or for tennis or skating? - The Forth Bridge
The Forth Bridge at the Present Day. Building the Bridge. Train crossing the Bridge. The mouth of the Forth has very nearly bitten Scotland in two, and anybody who wishes to travel from Edinburgh to Dunfermline would have to go a long way round if they objected to crossing the river. Formerly a great many people did object to this, because they knew that, although the voyage was only about a short mile, the great billows from the North Sea would meet them before it was over, and give them a very unpleasant time. So everybody who had anything to do with the Forth was willing that it should be spanned by a reliable bridge, and plans for carrying this into effect were frequently proposed. Indeed, arrangements were almost completed in 1879 for building a huge suspension bridge from shore to shore. The drawings were made, the estimates prepared, and the spades and trowels even beginning to work on the foundations, when, one sad December night, a terrible gale arose. All through the hours of darkness it roared and shrieked across the British Isles, working havoc upon sea and land, but, when morning came at last, few were prepared for the appalling catastrophe it had caused. Sweeping up the Firth of Tay, it had torn away a portion of the great railway bridge that crossed the inlet, and hurled it into the water. A train was passing over at the time, and plunged into the abyss with all its passengers. The terrible event shook public confidence, and we might almost say that the gale of that December night caught all the drawings and papers connected with the proposed suspension bridge over the Forth, and swept them from public favour. Immediately afterwards, Sir John Fowler and Mr. Benjamin Baker (both celebrated engineers) came forward with an alternative plan of which no one could doubt the strength. It may perhaps be described as an arch-suspension bridge, because the design includes the strength of both styles; but engineers themselves call it a cantilever bridge. - Close on his heels
Boys in gym class - Methods to get to the right place in a garage
When putting the car in place in the garage you must also maneuver carefully. The main thing is that you get in your place and as best you can. Too much brio results in broken walls and bent mudguards. If it makes you nervous, this twisting back and forth, feel free to leave it to someone else. It is not everyone's job and it is precisely with this shunting that small causes can have major consequences. [Translated online from the Dutch ] - Overtaking a tram
When overtaking a tram, also pay attention to the possibility that someone will jump in front of or from the tram. Giving a good signal and leaving as much road width as possible between the tram and your car is required. To catch up with a steam tram that hurls its plume over the road, and you it obstructs the view, it is advisable to wait until the wind chases away the steam. For the distance required to overtake a fast-moving vehicle such as a tram is too long, that the chance would not become too great that, in time, it would take to catch up with the plume of steam and drive through it. , in the meantime, a road obstruction would arise from the other side, which you would not have been able to see approaching. If you come across such a vehicle, moderate your speed so that you can stop vehicles suddenly emerging from that plume of steam. Give a strong signaland if necessary, stop the car on the right side of the road, until the tram has passed. Because then you have the most certainty, because then only a vehicle moving faster or as fast as the tram can cause danger. And this danger can be averted by giving a signal and keeping the right side of the road well. [Translated online from the Dutch ] - Parking
When you stop in a street, don't forget to reach out first, as a sign for the vehicle following you. Place your car neatly along the sidewalk, not crooked or in such a way that traffic is obstructed by it. You must intervene two vehicles or cars get into the car, then drive a little further, and then reverse between the cars. Do not drive straight over to the left side of the street, against the traffic, but drive to the right and then turn along the direction of the traffic, until you are in front of the house, where you want to be. [Translated online from the Dutch ] - Room to pass
It is also important to know, if you have to go through or along somewhere close with your car, what width you need. That can become such a certainty for you that it will look like virtuosity to the uninitiated. It's a matter of routine, of course, but it can be extremely practiced. It must be started with calculating the extreme points of the fenders. Later on, even this aid is often redundant. The best way to learn this is to place two blocks of wood on the ground, or to drive two posts, which are measured just the width of the wagon apart. Riding on that is the means of learning to estimate a narrow passage. Is the width wide enough to pass, but what When measured tight, keep flat on the side of the traffic obstruction, which is on your and steering wheel side. After all, here you can see exactly how close you can get without the risk of a collision. The other side will then be free of itself. [Translated online from the Dutch ] - Turn Signal
If you have to take a side road on the right, keep your arm stretched out in horizontal direction outside the car. [Translated online from the Dutch ]
