Blimp bombing a submarine - Blériot’s Toury-Artenay aëroplane circuit, 1908
Blériot would improve that record at once, by flying in a closed circuit embracing several villages. His renowned cross-country flight was directed from Toury to Artenay, a village nine miles distant. Mounting his aëroplane VIII-ter, at mid afternoon, in presence of a large gathering, Blériot followed the course shown. In the neighborhood of Artenay he landed for a few minutes. After some slight repairs to his magneto, he reascended, turned about and headed for home. Half way on his return course he stopped again for a few minutes, at the Village of Santilly; then readily reascended and flew to the neighborhood of his starting point. He thus traveled about 17 miles in a closed circuit. This performance, with that of Farman the day before, inaugurated the period of aërial voyages in heavier-than-air machines. - Blanchard’s flying-machine
One of the earliest authenticated devices of this kind was the invention of Blanchard, described by him in the Journal de Paris, August 28, 1781, nearly two years before the invention of the hot-air balloon, of which he became later an enthusiastic votary. As his device is but one of a large number that appeared before the close of the nineteenth century, and the advent of light motors, the reader who wishes fuller acquaintance with man-driven airships may be referred to Mr. Chanute’s book, entitled Progress in Flying-Machines, which describes a large variety of such inventions, and discusses the merit and weakness of each. - Blanchard’s dirigible balloon, 1784
The first attempts at balloon propulsion could not be seriously regarded by trained engineers, even at the inception of aëronautics; but still, as infantile steps in the new art, they may deserve passing notice. Blanchard, on March 2, 1784, made the first real effort to steer a balloon, using for that purpose a spherical gas bag and car provided with aërial oars and a rudder. As he was about to ascend, however, from the Champs de Mars, a young officer with drawn sword persisted in accompanying the pilot, thus compelling Blanchard to leave his wings on earth to allow sufficient buoyancy for himself and his obtrusive guest. His first trial was, therefore, frustrated; but subsequent ones made with that inadequate contrivance also proved futile under the best circumstances; for the scheme was evidently puerile, though tried by various grown-up men besides M. Blanchard. - Biva

- Besnier’s Apparatus
Of the devices suggested [for man to fly] many showed ingenuity; and some were quaint, in view of what we know of flight to-day. In the machine, for instance, designed by an experimenter named Besnier—who was a locksmith by trade—there were four lifting planes, closing on the up-stroke and opening on the down, and these the operator was to flap by the use of his hands and feet. - Besnier and his wings
In 1678, Besnier, a French locksmith, constructed a curious flying machine consisting of two wooden bars which rested on his shoulders. At the ends of the bars he attached muslin wings, arranged to open on the down stroke and close on the up stroke. The wings were operated by moving the arms and legs. Although Besnier failed to realize that no man had sufficient muscular strength to fly as the bird flies, he did sense part of the truth—that gliding with the air currents was possible. During his experiments he is said to have jumped from a window sill, glided over the roof of a near-by cottage, and landed on a barge in the river. - Berg 15-Horsepower chassis
Berg Automobile Co. The Berg company shows the chassis of two and four-cylinder cars. In each model the transmisson is through sliding gears, propeller shaft and bevel gear final drive. The entire running gear construction is substantial, the wheel base is long, the springs long and wide and the axles heavy. The braking system includes expanding hub brakes. The two models are rated at 18 and 24 horsepower respectively. - Bell’s ‘Comet,’ off Dumbarton on the Clyde, 1812
Nothing more was heard of the steamboat in Britain until 1812, when Henry Bell surprised the natives of Strathclyde by the following advertisement in the Greenock Advertiser: STEAM PASSAGE BOAT, “THE COMET,” Between Glasgow, Greenock and Helensburgh, for Passengers Only. The subscriber having, at much expense, fitted up a handsome vessel, to ply upon the River Clyde, between Glasgow and Greenock, to sail by the power of wind, air and steam, he intends that the vessel shall leave the Broomielaw on Tuesdays, Thursdays and Saturdays, about mid-day, or at such hour thereafter as may answer from the state of the tide; and to leave Greenock on Mondays, Wednesdays and Fridays, in the morning, to suit the tide. The elegance, comfort, safety and speed of this vessel requires only to be proved to meet the approbation of the public; and the proprietor is determined to do everything in his power to merit public encouragement. The terms are, for the present, fixed at 4s. for the best cabin, and 3s. for the second; but beyond these rates nothing is to be allowed to servants, or any other person employed about the vessel. The subscriber continues his establishment at Helensburgh Baths, the same as for years past, and a vessel will be in readiness to convey passengers to the Comet from Greenock to Helensburgh.

Bassoon, a woodwind instrument with double reed mouthpiece, a member of the oboe (q.v.) family, of which it is the bass. The German and Italian names of the instrument were bestowed from a fancied resemblance to a bundle of sticks, the bassoon being the first instrument of the kind to be doubled back upon itself; its direct ancestor, the bass pommer, 6 ft. in length, was quite straight. The English and French names refer to the pitch of the instrument as the bass of the wood-wind. - Basset Horn
Basset Horn: a wood-wind instrument, not a "horn," member of the clarinet family, of which it is the tenor. The basset horn consists of a nearly cylindrical tube of wood (generally cocus or box-wood), having a cylindrical bore and terminating in a metal bell wider than that of the clarinet. - Barrel Organ
Large stationary barrel-organ worked by hydraulic power, from Solomon de Caus, Les Raisons des forces mouvantes (Frankfort-on-Main, 1615). The origin of the barrel-organ is now clearly established, and many will doubtless be surprised to find that it must be sought in the Netherlands as early as the middle of the 15th century, and that accurate and detailed diagrams of every part of the mechanism for a large stationary barrel-organ worked by hydraulic power were published in 1615 - Barrel and breech of 5-cm Pak
- Barbiton
Barbiton , an ancient stringed instrument known to us from the Greek and Roman classics, but derived from Persia. Although in use in Asia Minor, Italy, Sicily, and Greece, it is evident that the barbiton never won for itself a place in the affections of the Greeks of Hellas; it was regarded as a barbarian instrument affected by those only whose tastes in matters of art were unorthodox. It had fallen into disuse in the days of Aristotle, but reappeared under the Romans. - Banked turn on a biplane
- Ballista - Caesar covered his landing in Britain with fire from catapults and ballistas.
The ballista had horizontal arms like a bow. The arms were set in rope; a cord, fastened to the arms like a bowstring, fired arrows, darts, and stones. Like a modern field gun, the ballista shot low and directly toward the enemy. - Balista

The whistle buoy at the left utilizes the motion of the waves to blow a whistle. The light buoy in the centre has an automatic light that burns gas stored in the body of the buoy.
