Title: Improvements in Vapour Electric Lamps or Rectifiers
Inventor: KRUH OSIAS OTTO
Filed: 1904-06-22
Granted: 1904-08-04
Abstract: 14,148. Kruh, O. O. June 22, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Vacuum tubes.-A vapour lamp or current rectifier for use in connection with inductance coils and alternating current is started by the production of an arc in a branch tube and afterwards of a discharge in the main tube of a sufficiently-high voltage, but not high enough of itself to cause a discharge. The lamp or rectifier and one arrangement of the apparatus in connection with it are shown in Fig. 1. On closing the circuit, current flows from the main 16 through a coil 20, the electrodes 4, 5, and a coil 14 to the main 15. The lifting of the core 12 breaks the mercury connection 3 and starts an arc ; reverse current then flows from the main 15 through a coil 21 and the electrode 4 to a non-fusible electrode 6 and the main 16. Current flowing through the primary coil 20, which in this arrangement is in parallel with the inductance coil 22, causes a discharge from the secondary coil 19 between the electrode 4 and the auxiliary electrode 9, from which depends a carbon filament 10 anchored at 11. Currents then start between the main non-fusible anodes 7, 8 and the cathode 4, and actuate cut-outs 17, 18. The primary of the starting-transformer is traversed by only a portion of the total current through the lamp. Fig. 2 shows diagrammatically another system of connections. The primary coil 25 of the transformer is in parallel with an inductance coil 26 in one of the mains, and the secondary coil 28 is arranged to be disconnected, when the lamp is running, by the cut-out 31. In a modification of this system, the primary coil 25 and the inductance coil 26 are short-circuited during the operation of the lamp, while the secondary remains connected. In another system (not shown), the primary coil of the transformer is connected through a cut-out similar to 18, Fig. 1, directly across the mains.

Title: Improvements in Steam Heating Systems.
Inventor: DONNELLY JAMES ALFRED
Filed: 1904-10-11
Granted: 1905-08-31
Abstract: 21,898. Donnelly, J. A. Oct. 11. Pressure regulating valves; hinged valves.-Fig. 2 shows a valve for regulating the pressure -difference between the supply and return mains of a low-pressure steam-heating system, and Fig. 3 a valve for restricting the flow through the radiators. The regulating - valve consists of a casing B, Fig. 2, forming two chambers 5, 18 separated by a flexible partition 16, the motion of which, together with the action of an adjustable weight 15, controls a double-beat valve 10, the seatings of which are formed in a U-shaped partition in the upper part of the chamber 5. The lower chamber 18 communicates with the highpressure main by means of a pipe 19. An increase of pressure in the supply main, or a decrease in pressure in the return main, thus diminishes the area through which the returning fluid can pass from the inlet 2 to the outlet 3 to the air pump, and vice versÔ. The restricting-device, Fig. 3, is placed between a primary heating-section and a secondary condensing-section of each radiator. It consists of a conical valve piece 24, formed with a suitable impact surface 25 and attached to one limb of a loaded lever 26. Under normal working the valve remains slightly open, but should the water of condensation collect in sufficient quantity, a jet of water is produced which strikes the surface 25 and throws the valve wide open.

Abstract: 25,283. Dolter, H., and Mertens, G. Dec. 6, 1904, [date applied for under Patents Act, 1901]. Brakes.-A band brake is applied by an electromagnet or electro-magnets connected directly to the ends of the band. In one arrangement, shown in Fig. 1, the two arms S<1>, S<2> of a horse-shoe electromagnet connected to the band are pivoted at a, and their motion is limited by stops A, B. If the brake wheel is rotating in the direction of the arrow, and a current is sent through the coils of the magnet, the band is tightened, and the arm S<1> is dragged against the stop A. If the wheel is rotating in the opposite direction, the stop B comes into use. In another arrangement, shown in Fig. 2, two magnets M', M<2> are used and the magnetic circuit is completed through the brake wheel. In this case the frictional drag of one of the magnets tightens the band. In a modification, shown in Fig. 3, and described in the Specification in the original form as published under the Patents Act, 1901, a single bell-shaped magnet connected to the band by hooks is used, and fixed hooks Z<1>, Z' are arranged to act as stops on the ends of the band. This subject-matter does not appear in the Complete Specification as accepted.

Title: Improvements in and relating to Electric Controllers.
Filed: 1906-02-21
Granted: 1907-02-07
Abstract: 4322. British Thomson-Houston Co., [General Electric Co.]. Feb. 21. Turrets.-In an electric controller, indicators are provided to show the positions of the controller contacts and of the device controlled. The turret 7, the movement of which is determined by the controller 1, is geared to the shaft 6 of the controller, the movable contacts of which are mounted on a hollow shaft 3 and rotated by a hand-wheel 5. The shaft 6 carries a pointer 8 which moves over graduations 9 on a disk 10 to indicate the angular position of the turret. A pointer 11 on the handwheel 5 indicates the position of the contacts, and therefore the direction and speel of rotation of the turret. A wheel 13 is fixed to the lower side of the disk 10, and a similar wheel 14 is fixed to the controller casing. A pair of pinions 15, 16, rigidly connected together, are mounted on the wheel 5 and gear with the wheels 13, 14. A second pair of pinions 17, 18 may also be used. As the bandwheel 5 is rotated, the pinions rotate by gearing with the stationary wheel 14 and so keep the wheel 13 attached to the disk 10 stationary. By this arrangement, the use of brackets to support the disk is avoided.
