Title: Improvements relating to automatically regulated direct current power supplies
Inventor: KING KENNETH GORDON
IPC: G05F1/38
Filed: 1963-09-10
Abstract: 1,034,206. Automatic voltage control. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Aug. 14, 1964 [Sept. 10, 1963], No. 35658/63. Heading G3R. An automatically regulated D.C. power supply system comprises an A.C. source connected over a regulator R to a rectifier U, a smoothing filter L1, C1, L2, C2, and a controller CR which converts a sensing signal S received from an auxiliary winding 2 of inductor L2 into a control signal for the regulator R. The auxiliary winding 2 is connected to the output terminal OP of the system and is inductively coupled to the main winding 1 of inductor 2; the signal S is thus dependent (from the D.C. aspect), upon the output voltage at terminal OP and, from the aspect of the alternating current components, upon the unsmoothed input IP to the filter, whereby, it is stated, difficulties encountered by the occurence of oscillation due to phase shift in the smoothing filter are mitigated. In a multi-stage filter, each inductor such as L1, L2 may have an associated auxiliary winding (Fig. 3,not shown). The regulator R may be a transductor, and the controller may include an emitter coupled balanced transistor amplifier having a reference diode (Fig. 4, not shown). The D.C. voltage drop across an auxiliary winding may be used as a sensing signal for current limitation. Thyristors may be used for the regulating means, and the arrangement may be applied to D.C. chopper regulators.

Title: Improvements in or relating to liquid electric switches
IPC: H01H33/75
Filed: 1931-12-24
Abstract: 384,818. High-tension switches. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, 'Berlin. Dec. 24, 1931, No. 35740. Convention date, March 11. [Class 38 (v).] In a switch of the liquid-immersed contact type the pressure developed by the arc at break forces the liquid above the gas bubble in the form of a freely-moving liquid piston which is guided by channels into the exhaust space. In the construction shown in Fig. 2, the arc drawn between the pin electrode and the fixed electrode 19 forms a gas bubble and, when the pressure therein is adequate, the liquid in the tube 20, which forms an extension of the switching chamber and terminates in spiral form finally opening to the atmosphere, is forced with a minimum of impediment out of the tube. The gas bubble is thus allowed to expand freely ; the ejected liquid returns through the pipe 21. In the construction shown in Fig. 4, two guide tubes 26, 27 for the liquid piston are arranged one at each side of the switch chamber. In Fig. 5, the break takes place within a cellular structure of superimposed plates held together on pins 36, 37 by springs 40, 41. This construction ensures that sufficient pressure is developed in the gas bubble before it forces apart the plates, as shown, and sets in motion the two liquid pistons 43, 44.

Motors 11, 13 drive the rollers 10, 8 via bands 12, 14 or a reversible gear drive and in operation either to dispense or store film one roller is driven while the other is braked. In modifications, Fig. 3 (not shown), a single motor (211) drives both rollers 8, 10, via gears (121, 122, 123, 124); an electrically operable clutch (126, 128) and brake (130, 129) are provided for each roller. Also, Fig. 4 (not shown) a motor and a clutch drive each roller through a non- reversible worm gear. In operation to keep up tension in band 7, the speed of one motor may be controlled by the other through use of one of the motors as a tachogenerator connected in an external circuit. A device coupled to the shaft of one of the rollers is provided for indicating whether the magazine is full or empty, the quantity of film in the magazine is also indicated by the angular position of the shaft. In another embodiment, the first roller is replaced by two driven rollers (100, 101), Fig. 6 (not shown) having a belt (102), preferably band 7, passed therearound. Also in Fig. 7 (not shown) two belts (71, 72) and two second driven rollers (81, 82) may be provided. A polarized relay with magnetic latching to hold it in either position (Fig. 5, not shown) is controlled by signals from the magazines and itself determines whether motor 11 or 13 is energized. Alternatively the motors can be controlled by a photo-cell located at the magazine entry and responsive to iron-actinic radiation.
