Title: Improvements in Systems of Electrical Distribution and Circuit-breakers for Use therein.
Inventor: STILLWELL LEWIS BUCKLEY
Filed: 1899-12-22
Granted: 1900-12-22
Abstract: 25,422. Stillwell, L. B. May 24, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Distributing; cut-outs.- In systems of distribution in which the energy is transmitted to sub-stations and then distributed, cutouts are employed which are controlled by a time mechanism so that the main circuits may not be opened should a shortcircuit occur on one of the branches. Fig. 1 shows one form of circuitbreaker. The main 1 has in it the primary 2 of a transformer. In circuit with the secondary 4 is an electromagnet 6 and the electromagnet 17 of the circuit-breaker. The armature 7 of the magnet 6 is connected to a pawl 11 acting as a stop to the time mechanism, which tends to drive an insulating-disc 14 fitted with a contact-strip 15. A brush 16 rubs on this conducting-strip, and so short-circuits the magnet 17. Should an excessive current flow through the magnet 5, the clock mechanism is freed, and after a predetermined time the insulating-portion of the disc 14 comes in contact with the brush 16, and the magnet 17 is energized. Circuit-breakers having different time elements are fitted in different parts of the system.

Title: Improvements in Hydraulic Brakes for Railway and Tramway Vehicles.
Inventor: DUREY CAMILLE
Filed: 1900-06-12
Granted: 1900-08-25
Abstract: 10,727. Durey, C. June 12. Brakes, hydraulic. Relates to improvements in the operating- apparatus of hydraulic brakes of the kind described in Specification No. 21,816, A.D. 1899. The chest 5 has four valve-controlled chambers 6, 7, 8, and 9 communicating respectively with the reservoir 4 pipe 14, space g, and brake cylinder 3. The pump 1 is actuated by an eccentric on the vehicle axle. The cam d and a piston f control the lift valves a, b, c, and, when the lever l is in the position marked I, the valve a only is open, allowing water to be drawn from the chamber 4 by the piston f on one stroke and discharged, one half through the valves band c and pipe 16 to the space h, and the other half through the pipe 15 to the space g, to be discharged from it to the cylinder 3 on the return of the piston. The water pumped to the cylinder 3 first moves the brake piston bodily until the brake is applied, and then moves the piston k to compress the spring r. When the wheels are on the point of skidding, the rod m forces back the valve s, and allows water to escape to the space h. On bringing the lever l to the position marked II, the valves a and b are opened, and the pump merely churns the water, the pressure in the cylinder 3 being maintained by the closed valve c. The brakes are retracted by placing the lever l in the position marked III, when the valves a, b, c are opened by the cam d and the brake cylinder is exhausted.

Abstract: 17,563. Skotnicki, V. B., and Ostrowski, Count A. F. Sept. 2. Sluice-gates.-Relates to automatic sluices or sluice-gates applicable for canal locks, stationary opening and folding weirs, fascines, and the like. The shutter a, b, Fig. 1, revolves on the horizontal shaft c, and has, for upper and lower abutments, the abutments e, d. The shutter opens on the rise of the water level beyond a certain limit, and, to close it when the water level falls, two leaves f, g, placed on the outer side, are arranged as shown. These leaves may be immovably fixed to the shutter, or may be movably arranged as shown in Fig. 5, and they may be open at suitable parts. When movable, the leaves f, g depend from the shutter and open on the shutter being lowered, and their movement can be restrained by means of moving bolts, catches, chains, or the like. If a chain is used, it is fixed to the inner side of the outer leaf, and, passing through openings in the intermediate leaf or leaves and in the shutter, it passes over pulleys on the shutter to the pillars or side walls of the sluice. Fig. 8 shows the application to a weir. The pillars 2 are kept erect by struts 4, and are lowered after loosening the chain 9 by means of winches 3. Trolleys may be run along rails which are supported on brackets provided on the pillars to connect the piers and the shore. Prior to lowering the pillars, the catches 18 are disengaged from the brackets 14. In another application, the shutters are adapted to a folding weir. The leaves are then in the shape of long narrow boards, and the exterior boards are fastened by hooks direct to the frames, and are provided with abutments, while the inner boards are suspended on the horizontal shaft c and are fastened together to form one shutter.

Filed: 1902-01-22
Granted: 1903-01-08
Abstract: 1758. Salinen-Direction L³neburg and Sachse, O. Jan. 22. Salt, common.-Brine is first purified of its calcium salts, and then evaporated in vacuum boilers ; the salt obtained is afterwards treated with solvents for the readily-soluble impurities. In one method, sodium carbonate is added to the brine to the amount of a 7 to 10 per cent. excess of that required theoretically to precipitate the whole of the lime, and the mixture is kept stirred for from 5 to 6 hours while at a low temperature. The calcium salt is precipitated, mixed with a small quantity of some magnesium compounds. After separation, the brine is evaporated in vacuum pans, and is finally washed with pure brine, steam, or water in a centrifugal apparatus. In a modification, magnesium sulphate, sometimes mixed with other sulphates, such as sodium sulphate, is used instead of soda. The mother liquor and the washing-liquor from the centrifugal apparatus may be added to the brine.
