Title: Improvements in Switches for Alternating Electric Currents.
Inventor: HOPKINSON BERTRAM
Filed: 1899-05-24
Granted: 1900-05-19
Abstract: 10,863. Hopkinson, B. May 24. Switches and cut-outs for alternating currents are so arranged that contact is finally broken when the current is approximately at zero value. An electromagnetic switch is arranged in shunt with the main switch, the armature and core forming the contacts. When the main switch is opened, the armature is held by the magnet until the current sinks to zero, when the armature is pulled off by a spring. in the form shown in Fig. 2, A is an adjustable electromagnet and B the armature sliding in a case C. The armature is connected by a flexible wire E with a sliding cylinder F connected to a spring H which tends to lift the cylinder and armature. When the main switch K is closed, the cylinder is pressed down by a bar I and locked in that position by a rod M connected to a lever R, which in turn is connected to the switch lever by a string T. When the main switch is opened as shown in dotted lines, the rods I and M are drawn away from the cylinder, and the armature is then held down only by the magnet. When the current sinks to zero, the spring draws off the armature, so completely breaking the circuit. A condenser may be arranged to prevent sparking between the armature and magnet. In the modification shown in Fig. 5, adapted for a quick-break circuit-breaker, the armature is normally pressed against the magnet by a spring H' surrounding a tube G, while a spring H within the tube tends to withdraw the armature. When the main switch is opened, a fork L compresses the spring H<1> and allows the spring H to operate. With very high potential circuits, several shunt switches may be arranged in connection with a main switch.

Title: Improvements in Looms.
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1899-06-13
Granted: 1900-04-14
Abstract: 12,346. Thompson, W. P., [Harriman, H. I.]. June 13. Loom shuttle - changing mechanism; driving- mechanism; shuttle - relief motions. - The speed of the loom is automatically reduced, and the picking- motion put nut of action, for a definite period, whilst the weft is being replenished in case of breakage or exhaustion. In the particular form of mechanism shown, the front 22 of the shuttle box is raised by arms 23 on a rocking-shaft 25 to allow a slide 29 to eject the exhausted or used shuttle, and a new shuttle 16 from a hopper 15 to be placed in the shuttle box by a pusher 17 on an arm 18 pivoted at 19. The slide 29 is operated by an arm 61 on a rock-shaft 62, and an oscillating arm 32 on the lay acts to relieve the pressure of the protector fingers 30 on the swell 28 just before the front 22 of the shuttle box is raised. All these motions are effected by means of flexible connections 55, 60, 70, 67 from levers 54, 59, 69, 66 actuated by cams 53, 58, 68, 65 on the shaft 33, which is put into operation by any ordinary weft-actuated devices. In the form shown, the rock-shaft 104 of the ordinary weft-fork mechanism has an arm 105 with a pawl 106 to actuate a ratchet-wheel 108 on a shaft 110. This shaft has a cam disc to operate an arm 113 on a shaft 95, which has another arm 94 to put into action a clutch on the shaft 12 for communicating motion by sprocket gearing 87, 88 to the shaft 33. The rotation of this shaft not only effects the motions previously described, but by means of a cam 76, lever 77, and flexible connection 78 unhooks the link 80 for operating the picking-stick 5, and thereby puts the picking-mechanism out of action. The clutch is kept in operation during a complete revolution of the shaft 33 by means of another arm 114 on the shaft 95 engaging with a catch 115 on a rock-shaft 116, which has an arm 117 to be operated by a tappet 118 on a disc 119 for the purpose of disengaging the catch at. the proper time. The reduction of the speed of the shaft 12 is effected by cam discs at the other end of the shaft 33, which shift the ordinary driving-belt from the fast pulley to the loose, and at the same time shift a driving-belt with slower gear from a loose pulley to a fast. In a modification, a single belt-shipper is employed, and a loose pulley operates the shaft through pawl and ratchet gearing and intermediate chain and sprocket gearing for reducing the speed. The cam disc on the shaft 110 is arranged to re-start the picking at the end of a cycle of shed formations, or a multiple of cycles, counting from the pick which failed. The pressure on the swells is removed prior to a pick, and again applied before the shuttle completes its flight, by a lever pivoted on the connecting-rod and operated by a cam on the frame of the loom.

Title: Improvements in Processes of and Apparatus for the Manufacture of Nitrogen Compounds from Athmospheric Nitrogen.
Inventor: BRADLEY CHARLES SCHENCK
Filed: 1900-04-24
Granted: 1900-06-23
Abstract: 7558. Bradley, C. S., and Jacobs, C. B. April 24. Carbides; barium, calcium, potassium, and sodium salts.-Relates to the production of cyanides by the fixation of atmospheric nitrogen by means of carbides. A porous mixture of a carbide of an alkaline-earth metal, preferably barium carbide, and an excess of carbon is first prepared as follows :- (1) by mixing granulated barium carbide and coarsely-ground coke, and heating this mixture in an electric furnace until the carbide becomes pasty ; or (2) by heating a mixture of barium carbonate or barium hydrate and an excess of coarselyground coke in an electric furnace ; or (3) by heating a mixture of barium carbonate and soft coal to a coking heat in an ordinary retort oven, and then further heating the intimate and porous mixture of coke and barium carbonate thus produced in an electric furnace. The porous carbide mixture produced by either of these processes is allowed to cool below the fusing point of the carbide, and is then acted upon by a current of nitrogen. The furnace employed may be a rotary one, consisting of a shaft 1 connected by spokes 2 with a rim 4, and driven through gearing 7 by a motor 6. A receptacle for the mixture is formed by attaching cover-plates 4<1> to the rim. Two electrodes 5, adjustable by screws 5<1>, conduct the electric current through the mixture, and pipes 8, communicating by a pipe 9 with a gas reservoir 10, conduct the nitrogen to the mixture as it solidifies. The pipes 8 are closed in their upper positions by the top of the pipe 9, as shown in Fig. 2, or each pipe 8 may be fitted with a separate cock which is operated automatically by fixed tappets as the furnace revolves. The plates 4<1> are taken off as they come to the delivery side. The mixture is then removed, and the barium cyanide produced is extracted with water. It may be converted into sodium or potassium cyanide by precipitating the barium by means of sodium or potassium carbonate, and the mixture is then filtered and concentrated to crystallization.
