- Wright Motor and Propellers
When the Wrights had built an engine, there was still the question how they should make it drive their aeroplane. They inclined naturally to the idea of an aerial propeller. Two courses lay open to them; they could fit one propeller running at high speed and coupled directly to the motor, or they could use two propellers, revolving at slower speed and geared in some way to the engine. They decided upon the latter course, placing two propellers behind the main planes of their machine and driving them from the engine by means of light chains, these running in guiding tubes. This system of propulsion is shown. A. Motor; B. Gear-wheels upon motor crank-shaft; C.C. Tubes carrying driving chains; D.D. Sprocket-wheels over which chains pass; E.E. Propellers. - Wright Launching Rail
A. Biplane; B. Rail; C. Rope passing from the aeroplane round the pulley-wheel (D.) and thence to the derrick (E.); (F.) Falling weight. Details of propulsion and control being arranged, there remained the question of how the machine should be launched into the air. In their gliding tests, it will be remembered, the Wrights employed assistants, who held the machine by the wing-tips and ran forward with it. But the weight of the power-driven machine, and its greater size, prevented such a plan as this. They decided, therefore, to launch it from a rail, and to aid its forward speed, at the moment of taking the air, by a derrick and a falling weight. - Wings
Wings - Voisin Glider towed by a motor-car
In the launching of gliders, some French experimenters showed ingenuity. The brothers Voisin, for instance, who played a prominent part in the early tests in France, adopted the plan illustrated. The gilder was towed by a motor-car across an open stretch of ground; then, when its speed was sufficient for the planes to lift, it rose and flew behind the car like a kite. - Voisin Glider on the river Seine
A form of glider, mounted upon hollow wooden floats—anticipating the sea-plane of to-day—and towed upon the river Seine by a motor-boat. This gilder also, when its speed became sufficient, rose into the air. In the construction of the machine, a biplane, one notes resemblances to the method of the Wrights; and yet generally the craft is dissimilar. - Typhon

When the land was divided into separate estates or properties, Thoth, the Pillar or Landmark at the corner of the field, became an important god; and as the owner's name was carved upon it, he was the god of letters and of all learning. - The Wright Wing-warp
Apart from governing the ascending or descending movement, there was the question of preventing a machine from slipping sideways; and this the Wrights solved ingeniously. They saw, of course, that when their glider lurched to one side or the other, they would need some power to tilt it back again. So they devised a system by which the plane-ends of their machine—being made flexible—might be warped, or caused to shift up and down. This action the operator controlled, as he lay across the lower plane, by a movement of cords, and its operation is shown in Figure. The effect upon the machine may be described thus: should a wind-gust tilt down one plane-end, the “warp” upon that side of the machine was drawn down also, and the effect of this—seeing that it caused the plane to assume a steeper angle to the air and exercise a greater lift—was to raise the plane-ends that had been driven down by the gust. By a system of connecting the control cords, this balancing influence was made to act with double force; when one wing warped down, the other moved up; and, in this way, while the side of the machine tilted down was made to rise, the other plane-ends, which had been lifted, were made to descend. A dual righting influence was thus obtained. This system, which imitates the flexing movements made by a bird, was an important device; the Wrights patented it—combining the movement with an action of the rudder—and brought cases at law to enforce their rights. - The Wright Biplane

It is now possible to describe, as a completed craft, the Wright power-driven plane; The picture shows its appearance; and in looking at it one is struck by the fact that, save for one or two modifications, and the fitting of motor and propellers, the machine is practically a glider, such as the Wrights used for soaring tests. Of the changes to be observed, the most interesting concern the elevator and rear-rudder. The former, it will be seen, has a double plane; it is, in fact, a smaller biplane on the principle of the main-planes. Needing to increase the surface of the elevator, the brothers fixed one plane above another so as to make the construction stronger and occupy less space.

- The Maxim Machine
The engines drove two canvas-covered wooden screws, each 18 feet in length, and the general appearance of the machine is indicated by the picture. In these trials, although it was always captive, the aeroplane demonstrated much that its inventor had set himself to prove. In Sir Hiram Maxim’s own words, it showed that it had “a lifting effect of more than a ton, in addition to the weight of three men and 600 lbs. of water.” He adds: “My machine demonstrated one very important fact, and that was that very large aeroplanes had a fair degree of lifting power for their area.” - The Mather Kier, cross section
In the modern processes of bleaching cotton pieces the lime boil is entirely dispensed with, its place being taken by a treatment in the kier with caustic soda (or a mixture of caustic soda and soda ash) and resin soap. The best known and probably the most widely practised of these processes is one which was worked out by the late M. Horace Koechlin in conjunction with Sir William Mather, and this differs from the old process not only in the sequence of the operations but also in the construction of the kier. This consists of a horizontal egg-ended cylinder. - The George Inn, Salisbury

- The 1900 Wright Glider (operator’s position)
Their first glider was a biplane, with 165 square feet of lifting surface, as illustrated in figure; several of its features need explanation. First there is the position of the operator; he can be seen lying prone across the centre of the lower plane. This attitude was adopted by the Wrights to minimise wind-pressure. Should a man be upright in his machine, they calculated that his body would, as the glider passed through the air, offer an appreciable resistance; while, in lying flat, he would offer scarcely any resistance at all. - Staff slings, Longbows, Crossbows and Flail

The long list of gods was further increased in two ways. The priests sometimes made a new god by uniting two or three, or four into one, and at other times by dividing one into two or three or more. Thus out of Horus and Ra they made Horus-Ra, called by the Greeks Aroeric. Out of Osiris and Apis the bull of Memphis made of Osiris-Apis or Serapis. He carries the two sceptres of Osiris and has a bull's head. - Sea Creatures

Sea Creature - Santos-Dumont’s Biplane which flew at Bagetelle
It was not until 1906, at a time when the Wright aeroplane was capable of long flights, that a real French success was obtained; and then the flights made were brief, and carried out with a craft that was admittedly crude. It was a biplane of curious construction, built by the Voisin brothers for M. Santos-Dumont—a rich Brazilian who had spent money freely upon airships, and had been occupied, for some time before the Voisins made him this machine, with a craft having propellers to lift it vertically from the ground. Abandoning this idea, he devoted himself to the machine the Voisins built, which is seen in the picture. - Roller Washing Machine
The pieces are now run through a continuous washing machine, which is provided with a plentiful supply of water. The machine consists essentially of a wooden vat, over which there is a pair of heavy wooden (sycamore) bowls or squeezers. The pieces enter the machine at each end, as indicated by the arrows, and pass rapidly through the bowls down to the bottom of the vat over a loose roller, thence between the first pair of guide pegs through the bowls again, and travel thus in a spiral direction until they arrive at the middle of the machine, when they leave at the side opposite to that on which they entered. The same type of machine is used for liming, chemicking, and souring. - Robins’ Balistic Pendulum

The Chinese of the present day make use of a species of matchlock revolvers, and also of another matchlock, consisting of several barrels, placed on a common stock, diverging from each other, and fired simultaneously. - Rector and Doctor of the University of Paris
The Faculty of Theology, besides its dean, who was the senior doctor, chose every other year a syndic, whose business it was to administer the private business of the company. The Decree Faculty had only a dean selected by seniority in the grade of doctor, and the Faculty of Medicine had a dean elected every year from amongst the doctors in practice. Deans and proctors, to the number of seven, formed the higher tribunal of the University. The Faculty of Arts had, therefore, a clear majority of its own upon this tribunal ; it had, moreover, assumed for itself the exclusive right of nominating the rector or supreme head of the University, and he was bound to be a member of the faculty. - Queen Elizabeth’s Pocket Pistol
At Dover there is a culverine, presented to Queen Elizabeth, by the States General of Holland, and called Queen Elizabeth’s Pocket-pistol. It is 24 feet long, diameter of bore 4 1⁄2 inches, weight of shot 12lbs.; it was manufactured in 1544, and is mounted on an ornamented iron carriage made in 1827, at the Royal Carriage Department, Woolwich Arsenal. - Quarrels

Pthah, the god of Fire, was more particularly the god of Memphis, as Amun-Ra of Thebes; and the kings in that city were said to the "Beloved by Pthah." His figure is bandages like a mummy and his head shaven like a priest. - Powder Mill
The three ingredients are now ground separately to a very fine powder. The mills which effect this, and incorporate, are so similar, that a description will be given under the head of “Incorporation.” Screening.After being ground in this way, the saltpetre is passed through a slope cylindrical reel, covered with copper sieving wire of 60 meshes to the inch, which, as it revolves, sifts it to the required fineness, being then received in a box or bin underneath. The charcoal and sulphur are likewise passed through similar reels of 32 and 60-mesh wire respectively, and that which remains without passing through, is ground again under the runners. - Pierrier or Paterera
- Phillips’s Experimental Craft
Phillips built the strange-looking machine. It resembled, more than anything else, a huge Venetian blind; and he adopted this form so as to introduce as many narrow planes as possible. There were, as a matter of fact, fifty in the machine, each 22 feet long and only 1½ inch wide. The craft, as can be seen, was mounted on a light carriage which, having wheels fitted to it, ran round and round upon a railed track. A steam engine was used as motive power, driving a two-bladed propeller at the rate of 400 revolutions a minute. The machine was so arranged on its metals that, although the rear wheels could raise themselves and show whether the planes exercised a lift, the front one was fixed to its track—thus preventing the apparatus from leaping into the air, overturning, and perhaps wrecking itself. Tests with the machine were successful. The lifting influence of the planes, when the engine drove them forward, was sufficient to raise the rear wheels from the track; and they did so even when a weight of 72 lbs., in addition to that of the apparatus, had been placed upon the carriage. In his main object, then, Phillips succeeded; and that was to show the lifting power of his planes. But his apparatus had not the makings of a practical aeroplane. He gained for himself, nevertheless, a name that has lived and will live. - Pasht

- Osiris
There was a third class of gods, who were spoken of as if they had once been mortal and had lived upon earth. These were Osiris, the husband of Isis; and their sone Horus, so named from Chori (Strong); and Anubis, Nephtthys, and the wicked Typhon, who put Osiris to death. Osiris, like Pthah is bandage as a mummy. - Onager (Unslung)

- Onager
Of machines formed on the sling principle, that called Onager may be regarded as typical of all the rest. Its force entirely depended upon the torsion of a short thick rope, acting upon a lever which described an arc of a vertical circle. The lever had attached to its free extremity a sling, or sometimes it merely terminated in a spoon-shaped cavity. When bent back, it was secured by a catch or trigger, and charged with a stone. On starting the catch by a blow with a mallet, the lever described its arc of a circle with great velocity, and projected the stone to a considerable distance. - Old Eprouvette Pendulum
