Title: Improvements in and relating to Centre Valves for Gas Purifiers.
Inventor: PICKERING WILLIAM SELLERS
Filed: 1902-03-22
Granted: 1903-03-21
Abstract: 7087. Pickering, W. S. March 22. Purifiers.-A centre valve has a common inlet chamber b, a common outlet chamber c, and divided valve casings g, each containing a pair of double-faced valves i, h. Each purifier communicates directly with an inlet chamber l in one valve casing g, and with an outlet chamber k<2> in the next valve casing. Each valve, if moved outwards, places the corresponding inlet or outlet chamber l or k<2> of a purifier in communication with the common inlet or outlet chamber b or c ; if the two valves in one casing are moved inwards, the outlet and inlet chambers of adjacent purifiers are connected together through a cover j. The gas can thus be passed through the purifiers in series : or any purifier may be cut out by passing the gas to the common outlet chamber c. The common inlet and outlet chambers b, c may be arranged in various ways. In the form shown, for use on the underside of four purifiers, these communicate through openings in the top of the valve casings g with the chambers k<2>, l; the common inlet chamber b contains the tubular outlet chamber c, the main inlet and outlet f being adjacent, in the bottom of the apparatus. In another arrangement, the common chambers b, c are straight parallel channels, separated by a partition, special channels being provided connecting alternate chambers of the valve casings with the opposite common chambers ; the opposite valve casings at the ends of the apparatus are connected by transverse pipes. In an arrangement for use on the side of two purifiers, two casings containing pairs of valves are placed on opposite sides of a rectangular box, which is divided by a partition to form the common inlet and outlet chambers. Two similar arrangements may be used for a row of four purifiers, with two connecting-pipes, the common outlet chamber in each being an oblique pipe within a common inlet chamber.

Title: Improvements in or relating to Railway Breaks.
Inventor: PASS ERNEST DE
Filed: 1902-06-24
Granted: 1902-10-16
Abstract: 14,284. De Pass, E., [Soc. Anon. des Freins "Stop"]. June 24. Brakes, air. Relates to improvements in the apparatus for securing the simultaneous action of all the brakes in a train, as described in Specification No. 14,565, A.D. 1901. In Fig. 3, the part above the line A-B is omitted ; it is identical with that shown in Fig. 1, in which the diaphragm r controls the exhaust valve p corresponding to the valve p in the Specification quoted. Under normal conditions, air from the train-pipe b passes through the open valve t, and channel u to the pipe o of the brake cylinder, and the pressure on each side of the diaphragm is equal. On lowering the pressure in the pipe b, the diaphragm moves upwards, and the valve p uncovers the port q and allows air from the brake cylinder to escape to the atmosphere. In a modification, the valve p is controlled by a spring piston, which slides horizontally. In Fig. 3, the valve p is controlled by a differential device comprising a piston and a diaphragm r which act to reduce a fall of pressure in the train-pipe, instead of increasing the pressure as caused by the differential pistons described in Specification No 14,565, A.D. 1901.

Title: Improvements in Electric Control Systems
Filed: 1904-05-06
Granted: 1905-04-20
Abstract: 10,459. British Thomson-Houston Co., [General Electric Co.]. May 6. Motors, controlling.-The position of movable objects, such as brush-holders of motors, is controlled from a distance by means of a motor m which can run in both directions and is adapted to shift the brash-holder B by gearing D. The brush-holder carries two movable contacts d, d<1>, capable of engaging with the segments of the stationary commutator E, which segments are connected to the fixed contacts of the controller switch F. The three terminals of the motor mare joined to the controller and to the contacts d, d' as shown in Fig. 1, and Figs. 3 and 4 show suitable motors for alternating and direct currents respectively. When the controller is in the position shown in Fig. 1, there is no tendency for the motor m to rotate ; if, however, the controller be shifted so that the contact f<2> engages the stud g', the current through the contact d' is broken, and the motor rotates, shifting the brush-holder till the contacts d, d' are both in contact with the same segment and the current flows through the windings symmetrically, thus stopping the motor. The device operates similarly for other positions of the controller, and, if desired, by means of a spring. The motor m may be pulled out of engagement with the gear D, except when constrained by an electromagnetic device, and in this case the brush-holder may be returned by springs into any given position. As several motors may be operated from one controller, the system is particularly adapted for use on trains.
