Title: Improvements in electric selective distant control systems
IPC: H04Q9/16
Filed: 1926-02-16
Abstract: 271,544. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). Feb. 16, 1926. Selective distant control systems.-In an electric distant control system for selecting and operating any one of a plurality of machines, such as electric motors, means are provided whereby when a particular machine is selected, operation of the machine may be effected as often as desired. As shown in Fig. 1, the field resistance 31 of an electric generator 32 is regulated by two motors 1, 2 which are selected for operation by characteristic trains of impulses transmitted from control station A over the line wires 6, 7. If it is desired to regulate the generator by motor 1, the impulse transmitter 3 is operated to first close the circuit of the relav 19 and then intermittently energize the relay 5. The relay 19 disconnects the charging generator G from the battery 8 and closes the line circuit. The relay 5 transmits impulses of opposite polarity alternately over the line wires to energize the selector magnets 9 and step forward the switch arm 13. The selectors may be of the type described in Specification 117,170 wherein the switch arm 13, Fig. 2, is held in the selecting position by an arm 41 engaging the catch 40 on a wheel 39 carrying the switch arm. After operation of the transmitter 3, the arm 13 is held in a position one step short of the contact 14, and the other selectors connected across the line wires are released. In order to close the circuit of the motor 1 the common control key 12 at the control station is then depressed to send a further impulse over the lines and move the switch arm 13 into engagement with the contact 14 to energize the relay 10. The relay 10 closes the motor circuit and establishes a short circuit across the condenser 26 to permit continuous flow of current during operation of the key 12. If now the key 12 is released the switch arm drops back one step to stop the motor 1. Further regulation of the motor may then be obtained by again operating the key 12. The switch arm 13 is released by again operating the transmitter 3. This train of impulses moves the catch 40 out of the range of the arm 41 to permit the arm 41 to move into a position which lies within the circular path described by the catch 40 and thus allow the arm 13 to return to its normal position at the end of the impulse train.

Title: Improvements in or relating to gas-heated geysers
IPC: F16L19/03
Filed: 1931-02-12
Abstract: 372,416. Burner mountings. CHAPMAN, F. W., 14, Gonville Road, Thornton Heath, Surrey. Feb. 12, 1931, No. 4480. [Class 75 (i).] In a gas-heated geyser, the burner 2 is supported by a cross-bar 15 within a casing 1 at the bottom of the geyser and is connected to the gas supply pipe 10 by a detachable union 4 operable from outside the casing so that, on disconnecting the union, the burner can be withdrawn through the open bottom of the casing for cleaning purposes. As shown, a nut 9 is provided with an internal flange 11 behind a shoulder 12 on the pipe 10 and engages a threaded extension 5 of the burner which projects through an apertured plate 7 secured over a hole in the casing 1. The burner is provided with a depending lug 18 carrying a taper pin 19 for engaging a hole in, or the lower edge of, the cross-bar 15. The latter is resilient so that, when the nut 9 is operated to grip the extension 5 against the shoulder 12, the inner end of the nut is held in resilient engagement with the plate 7. In a modification, the nut 9 is adapted to clamp a shoulder 6 on the burner to the casing or an apertured plate attached thereto, a resilient washer being provided. In this case, the cross-bar 15 need not be resilient.

Abstract: 158,909. Soc. Materiale Elettro Trazione. Feb. 12, 1920, [Convention date]. Electrodes; moving; electrolytes, agitating.-In copper-plating the interior of on insulator, such for instance as is used in electric traction, the insulator forms the only receptacle for the electrolyte, which is kept in continual agitation therein. To maintain the concentration of the liquid, there is used a soluble anode which is rotated, or rotated and reciprocated. As shown, the anode c, protected near the surface of the liquid by an insoluble sheath f, is adjustably supported in a sleeve g by a collar l. The sleeve g revolves in a bracket i and is driven by a pulley h. A number of such brackets i may be attached to two beams m, between which is a shaft driving all the pulleys h; the pairs of eleetrodes are in series. The anodes c may be of spiral or cross form, or may have inward bends, or be provided with leaden or other insoluble wings, to promote agitation.

Abstract: 485,890. Wireless receiving systems. COLE, Ltd., E. K., and MARTIN, A. W. Feb. 17, 1937, No. 4728. [Class 40 (v)] A superheterodyne receiver, designed for rapid change-over from one to the other of two predetermined stations A and B, is such that when set to one station A the local oscillator generates a frequency which with the carrier of station A produces a sum frequency serving as the intermediate frequency, whilst on the operation of a push-button or like switch the oscillator circuit is changed to generate a new frequency which when subtracted from the carrier of station B produces the same intermediate frequency. In the system shown, with ganged switches 3, 12 in their upper positions condensers 5, 14 are adjusted to select station A. Operation of switches 3, 12 to their lower positions then tunes the input circuit by a, preset condenser 6 to the carrier of station B and adjusts the frequency of the oscillator by inserting a preset condenser 13.

Abstract: 888,436. Catches. CARTER, A. G. Feb. 14, 1958, No. 4914/58. Class 44. A safety-belt buckle comprises two components 20, 25, Figs. 2 and 3, locked in engagement by a spring-loaded cam member 36 which can be rotated by a lever 43 to permit disengagement of the components, the cam member 36 being rotated without corresponding movement of the lever 43 during reengagement of the components. The component 20 is provided with a slot 21 for receiving a loop of a belt 22 and with apertures 23, 24 which engage projections 29, 30 on the base 26 of the component 25, the apertures and projections having engaging surfaces 31, 32 forming an acute angle with a normal to the base 26, which angle has critical limits between 15 degrees and 30 degrees depending upon the surface finish. Alternatively the apertures may be on the component 25 and the projections on the component 20. The cam member 36 and the lever 43 are rotatably mounted on a shaft 34 non-rotatably disposed between flanges 27, 28 of the component 25, and a torsion spring 44 biases the cam member 36 to the locking position, one end 45 of the spring 44 engaging the cam member and the other end 46 engaging a lug 47 on a collar 48 also rotatably mounted on the shaft 34 and having another lug 49 which is engaged by a relatively stronger torsion spring 50 to urge the lever 43 to the locked position. When the lever 43 is raised an edge 42 thereof presses on the cam member 36 and the collar 48 to rotate these against the action of the spring 50, but when the component 20 is pushed into engagement with the component 25 it rotates only the cam member 36 against the action of the spring 44. Specification 888,437 is referred to.
