Granted: 1913-02-27
Abstract: 12,595. Gresham, H. E. May 28. Aspirating-apparatus, ejector; regulating.-In ejectors for vacuum or combined vacuum and steam brake apparatus, the air and steam valves are both actuated by a reciprocating rod operated by the control handle, which also actuates a disk valve controlling communication between the small ejector and the train-pipe. The valve e for admitting steam from a pipe d to the large ejector nozzle a, and a flap or mushroom valve f for admitting air to the train-pipe c, are actuated by a rod g, which is moved axially by a cam or crank i on a rotary spindle j carrying the control handle k. The rod g acts directly on the valve e, and operates the valve f through a lever h, one valve being opened while the other is shut. The communication between the small nozzle b and the train-pipe c is controlled by a disk valve m on the spindle j, the communicating port p being closed when the handle k is moved to apply the brakes, so that the small ejector continues to exhaust only the vacuum chamber of the locomotive brake apparatus by the pipe n. For preventing leakage of steam to the trainpipe when the ejectors are not working, two non- return valves t, u are provided between the small and large ejectors respectively and the main non-return valve q, and an air inlet valve v is fitted, as described in Specification 6284/10. A second air inlet valve w may be provided in connexion with the pipe n, as shown in Fig. 1. The ejector nozzles may produce solid or annular jets, or may be arranged as described in Specifications 18,830/08 and 11,236/09.

Granted: 1914-06-18
Abstract: 4485. Chapsal, F. J., and Saillot, A. L. E. March 20, 1913, [Convention date]. [Addition to 12,780/12.] Fluid - pressure.-The two diaphragms of the accelerator described in the parent Specification are replaced by a single diaphragm or piston, and the valve between the train pipe and the chamber above the diaphragm is modified to restrict the charging of the brake apparatus of the front portion of the train. A single diaphragm M operates a valve 15 leadiog to the venting-chamber P, and a valve T controlling an exhaust port 16 and a port 13 leading to the train-pipe 1 past the modified valve 6. Air from the train-pipe flows through ports 2, 3 to the underside of the diaphragm, which moves the valve T to uncover port 13, so that train-pipe air flows also through ports 4, 5, 7, past valve 6, and through ports 10, 11, 13 to the upper side of the diaphragm and to the branch leading to the distributor. If the flow of air is slow, the valve 6 is in position to open both ports 8, 9, but if the flow is sudden, as may occur at the front of the train, the valve 6 is moved to the close port 8 and to allow flow only through the restricted port 9. When an application is made, the valve 6 closes on to its seat 22, and the diaphragm M moves to open the venting valve 15 and uncover the port 16, which exhausts the branch leading to the distributor. In release, the valve 6 is at first in the closed position, and air from the train-pipeoperates the diaphragm M to open the port 13, whereupon air flows from the reservoir regulator or special releasing-reservoir through an annular port 12 and port 13 to the chamber above the diaphragm and the distributor, thus accelerating the release.

Title: Improvements in the Construction of High Frequency Alternators.
IPC: H02K19/34
Filed: 1913-11-22
Abstract: 17,872. Soc. Marius Latour et Cie. Nov. 22, 1912, [Convention date]. Alternating-current induction machines; rotary c o n v e r t e r s.-High frequency currents for wireless telegraphy or telephony are transformed in frequency by a number of pairs of single or polyphase windings acting in c a s c a d e and arranged around the frame of a single machine, a portion only of the frame periphery being used for each step in the transforma-' tion. Thus, as indicated in Fig. 3, by embodying four quadrantal sets of rotor and stator windings B<1> A<2>, A' B<2> ... B<7> A<8>, A<7> B<8> in a single machine four frequency increments are obtained. The first stator coils A<1> are excited by continuous current, and the rotor coils may consist of two short-circuited systems displaced by ninety degrees electrically, as shown. The winding arrangement of such a machine having two stator frames is shown diagrammatically in Figs. 4, 5, and 6. In this machine, the first stator coil A' receives continuous current and induces two phase current in the rotor coils B<1> A<2>. The coils A<2> in turn induce current of doubled frequency in the coils B<2>, and so on until current of eight-fold frequency is generated in the coils B<8>. The application to a single-phase generator is also shown in connexion with a machine having two windings extending around one half of the stator and cascaded with a plain squirrel cage rotor in such a manner as to give a single frequency transformation. The Specification as open to inspection under Section 91 (3) (a) comprises also the application to alternating-current machines of the homopolar type, by supplying alternating-current to that member of the machine which normally. carries continuous current and providing the machine with a laminated rotor. This subject-matter does not appear in the Specification as accepted.

Abstract: 1687. Wade, H., [Henkel et Cie.]. Feb. 2. Peroxides and perborates, obtaining; electrodes.-To an electrolyte containing oxygen and generating hydrogen peroxide at the cathode, there is added before or after electrolysis a soluble substance which forms with the hydrogen peroxide a sparingly soluble peroxide, peroxide hydrate, or perborate. Electrolysis can then be effected under atmospheric pressure, the temperature being preferably 0‹ C. Stability of the hydrogen peroxide may be promoted by starch, gelatine, boric or phosphoric acid, or potassium or sodium silicate. An electrolyte for producing sodium perborate contains 20 grm. borax, 4À2 grm. sodium hydrate, and either 22 grm. sodium sulphate or 30 grm. sodium phosphate to a litre of water. A diaphragm-tube separates the cathode, which may be of amalgamated silver, from the anode of platinum or lead. Oxygen is continuously fed into the solution, which is vigorously stirred. A current density of 20 amperes per square decimetre is suitable. For producing peroxide of calcium, barium, or strontium, a 1À5 per cent potash solution containing 3 per cent of the alkaline-earth hydrate is used. Peroxide of aluminium may also be prepared. The solid peroxides may be decomposed by sulphuric acid. Specification 8582/13 is referred to.
