Abstract: 484,824. Modulating and frequencychanging apparatus. GENERAL ELECTRIC CO., Ltd., FARREN, L. I., and GEORGE, E. P. Dec. 22, 1936, No. 35174. [Class 40 (v)] In frequency-changing apparatus of the type comprising one or more non-linear impedances to which the carrier and signal oscillations are applied, a rectangular waveform carrier is employed, the amplitude of which bears a defined relation to the extent of the curved part B of the characteristic of the impedance.- If ideal non-linear impedances, Fig. 6a are used with a carrier f2 and signal f1, the resultant frequencies are of the form pf2Œf1 where p is zero or an odd integer. If practical non-linear impedances, Fig. 6b, are employed the output contains undesired frequencies of the form nf2Œmf1, this is overcome by employing a rectangular wave carrier and a bias of such amplitudes that the signal frequency variations of voltage occur entirely within the linear portions A, C, of the characteristic. Specifications 428,708 and 473,944 are referred to.

Title: Improvements in indicating systems
IPC: G01F23/18
Filed: 1928-11-29
Abstract: 330,497. Slough, F. M. Nov. 29, 1928. Elastic-diaphragm pressure gauges.- Liquid level or pressure is indicated by opposing the pressure by a force due to electrically generated heat and measuring the heating effect by including an indicator in the electric circuit. The pressure of liquid in a tank 1, e.g. the fuel tank of a motor vehicle, is exerted on one side of a diaphragm 4 through a small aperture 13 in a tube 12 which damps out rapid fluctuations of level. Two bimetallic strips 14, 20 are mounted in the casing 7 with their free ends joined together and to the centre of the diaphragm 4. The strips are so arranged that on increase of temperature they tend to curl towards one another. An electric contact screw 25 is arranged below the strips and is in the circuit including a battery 28 and relay switch 31. When the pressure due to the liquid causes the strips to contact with the screw 25, and the contacts 29 are momentarily closed, a circuit is completed through battery 28, wire 42, relay 31, wires 33, and 32. The contacts 30 are thereby closed, and are substituted in the circuit for the contacts 29, so that current flows in the heating coil 43 surrounding the strip 20. This causes an upward force against the diaphragm 4 which ultimately breaks contact at the screw 25. The current flows also through a heating coil 36 surrounding a bimetallic strip 38, and the corresponding warping of the strip actuates a pointer 27 through rack and pinion 39, 40. The strips 14, 37 are for the purpose of compensating the effect of varying atmospheric temperature. The scale 41 is calibrated to indicate quantity of liquid or pressure. The pawl 45 prevents return of the pinion 40 until released by hand. A modification is described, Fig. 2, not shown, in which the switch 29 and relay 31 are omitted, and a continuous indication is given. In another modificalaminations of equal length arranged side by side omitted and the pressure on the diaphragm to oppose the liquid pressure is secured by the heating effect of the coil in the chamber 7 upon the enclosed air, or upon the vapour of alcohol or water. The indicator operates in a similar manner.

Title: Improvements relating to relays and other electrical switches
Inventor: LOBELLE MARCEL JULES ODILON
IPC: H01H9/54
Filed: 1960-10-17
Abstract: 924,281. Arc-suppressing in switches. M.L. AVIATION CO. Ltd. Nov. 3, 1961 [Oct. 17, 1960], No. 35508/60. Class 38 (5). An arc-suppressing arrangement for an electromagnetic relay or other switch comprises a transistor 6 having its emitter-collector path connected across the switch contacts 2 and its base connected to means which on the opening of the contacts apply a potential to the base to cause the transistor to conduct momentarily. As applied to a relay, Fig. 1, the means for applying the potential to the base comprises a coil 7 inductively related to the operating coil 1 of the relay. The coil 7 may be wound on the coil 1, or on the same former as the coil 1, or on a ferrite core provided with spring clips for fixing it to the coil 1. In the last case the ferrite core, the transistor and any associated components may be potted. Fig. 3 shows an arrangement in which a toggle or limit switch 2 is provided with a permanent magnet 13 which is moved relative to a fixed magnetic part 12 when the switch is opened so as to induce a current in a coil 11 and so render the transistor 6 conductive momentarily. In both arrangements a capacitor 9 may prolong the period in which the bias potential is applied to the base. Also a simple rectifying diode 8 may be connected in circuit with the base, though a bridge rectifier may be used if it is desired that the transistor should also conduct momentarily on closing the switch. In a further arrangement, a capacitor may serve as the means for applying the potential to the base, Fig. 4 (not shown). Reference is also made to the use of a single transistor in conjunction with a number of relays or other switches.

Title: A circuit arrangement including a transistor which conducts for a fixed period of time when the circuit is activated by an electrical pulse
IPC: H03K5/156
Filed: 1960-10-17
Abstract: 895,474. Transistor pulse lengthening and frequency dividing circuits. TELEFONAKTIEBOLAGET L.M. ERICSSON. Oct. 17, 1960 [Oct. 16, 1959], No. 35586/60. Class 40(6). A pulse lengthening circuit comprises a transistor Tl, Fig. 1, having an inductance L connected to its base and a capacitor to its emitter the other terminals of the inductor and capacitor being connected together and to a pulse source whereby a pulse will charge in the capacitor which thereafter will discharge resonantly through the inductor and the base emitter path of the transistor maintaining the transistor conducting for a half a cycle of the oscillation. Fig. 4 shows the application to a pulse frequency divider. The first pulse of a train applied to Cl renders a blocking oscillator transistor T5 conducting so as to produce an output pulse to render a transistor T3 conducting. This provides an output pulse in output winding N4 and also through N5 renders a transistor T2 momentary conducting. This applies a pulse to a circuit Tl, L, C corresponding to Fig. 1 so that the transistor T1 is rendered conducting for a predetermined number of pulses. Conduction of transistor T1 renders a transistor T4 non-conducting so disabling blocking oscillator T5 for n-1 pulses so that an outward pulse appears at winding N3 only for every n input pulses. It is stated that the invention is also applicable to arrangements for producing an "off" condition in a circuit during a fixed time by means of a pulse or for producing a signal at the end of a fixed time.
