Abstract: 1,001,664. Amplitude modulation systems; semi-conductor amplifying circuits. AKUSTISCHE UND KINO-GERATE G.m.b.H. April 13, 1962 [April 17, 1961], No. 14483/62. Drawings to Specification. Headings H3R and H3T. Carrier is applied to a bridge having an inductor and two capacitors in each of two parallel sides, the inductor being series resonant with one capacitor and the other two capacitors having a different capacity ratio from the resonance pair, and one of the capacitors in one arm is variable being part of a condenser microphone or of a pressure or pressure gradient transducer so that the output from another diagonal of the bridge is amplitude modulated. This output may be taken from between the ends of the inductors, the other ends being connected in common or through the non- resonance producing capacitors to a common point. The inductors and the capacitors may all be equal in reactance, but one capacitor shunted by a trimmer capacitor which adjusts the modulation ratio. A transistor oscillator may feed the bridge and the modulated output may be rectified to act as a low frequency amplifier.

Abstract: 1305698 Transistor radio receiving circuits MOTOROLA Inc 12 May 1971 [28 May 1970] 14499/71 Heading H3T A radio receiver includes a mixer circuit having first and second input terminals and an output terminal coupled to an I.F. utilization circuit, a local oscillator being coupled to the first input terminal of the circuit, while a radiofrequency amplifier circuit is connected in direct current series relation with the mixer circuit through an inductor connected to the second input terminal of the mixer circuit. Transistor 72 constitutes an R.F. amplifier in common emitter connection being fed from terminal 12a via tuned circuit 80, 81; its collector is connected via a signal-tuned circuit comprising inductor 76 and capacitor 79 to the emitter of transistor 73 which constitutes the mixer. In a first embodiment (Fig. 2, not shown) the R.F. transistor obtains a fixed base bias, and is neutralized by means of a capacitor connected between its base and the emitter of the mixer transistor. Transistor 87 constitutes the local oscillator, its emitter circuit comprising resistor 98 and being coupled to piezo-electric crystal 97 shunted by inductor 87; this is coupled by way of tuned circuit 90, 92, 93 to the collector of transistor 87. Local oscillations are injected on the base of transistor 73: the arrangement may employ continuously tunable circuits in order to cover a frequency band. The base bias for the oscillator 87 is derived via a D.C. amplifying transistor 78 from the emitter voltage of the mixer transistor 73. The collector circuit of mixer transistor 73 comprises a resistor 83 shunted by capacitor 84 and is D.C. coupled via diode 102 to the base of a first I.F. amplifying transistor 100; this is D.C. coupled to a second I.F. amplifying transistor 106, from the collector potential of which a base bias for the transistor 72 is derived over a line 113.

Title: Train-actuated electric track contact devices
IPC: B61L1/06
Filed: 1939-05-15
Abstract: 528,863. Train-actuated electric contact devices. GOMBOS, L., and ASZALOS, L. May 15, 1939, No. 14518. [Class 105] An electric contact device operated by rail deflection has the mechanical connection to the rail of such a form as to be unaffected by longitudinal movement of the rails or by change of gauge, no spring being used to maintain the mechanical connection. The contact device may be mounted on a base within the ballast or may be attached to the rail. In the latter case the above mechanical connection obviates the need for strict accuracy in manufacture. As shown, the contact device is attached to the rail, the contact box 5 being supported on two longitudinally spaced arms 2 extending from the rail 1. The operating lever pivoted at 6 has on its short arm a transversely cylindrical end 7a engaging in a channel box 9 fixed to the web of the rail at a point intermediate the two support arms ; thus the lever is operated only by a vertical movement of the rail. The long arm 7 of the lever has an adjustable link-and-pin-slot connection 15, 13 to a tubular member 12b which is thus rocked on a bracket 10. The tubular member 12b carries spring-controlled pivoted contacts 17a which co-operate with a contact 20 on a leaf spring 19 extending from the bracket 10.

Abstract: 435,062. Plug couplings combined with switches. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and JACOBS, H., c/o General Electric Co., Wembley, Middlesex. May 14, 1934, No. 14526. [Class 38 (i)] The plug member of a coupling is locked in engagement with the socket member when a switch on the latter is closed by a screwthreaded spindle 44 that turns in a block 25 associated with the earthing-socket 8 and grips the earthing-pin therein. A lever 43 on the spindle is acted upon by two arms 39, 40 carried by a slide 37 connected to the switch-operating lever 13. The slide has a projection 46 corresponding to an aperture 52 in a locking-plate 47 that prevents the switch from being closed in the position shown in Fig. 2, but is slid to the right so as to allow the projection 46 to move into the aperture 52 when the plug member is inserted, the earthing-pin depressing a cross-bar on a sliding ring 20 surrounding the earthing-socket and pressed forward by a spring 24, connection between the plate 47 and ring 20 being made by a bell-crank lever 27. The switch consists of double-pole bridging-contacts 55, 56 cooperating with clip contacts 57 connected to the terminals 60 and to the supply sockets. The slide 37 may act positively on the switch arm 54 during the first part of the opening movement, but the main connection between the lever 13 and arm 54 is made through a quick make-and-break toggle mechanism. The switch mechanism and socket contacts are mounted on a plate 14 carried by the cover-plate 1 with spacers 16 between. The connection between the switch and the screwed spindle for locking the plug in the socket may be made through a spring.

Abstract: 631,766. Gauging screw-threads. TRIGGS, W. W. (Niles-Bement-Pond Co.). June 2, 1947, No. 14572. [Class 106 (ii)] A gauge for external taper screw-threads comprises a body 10 having annularly-grooved rotatable gauging members 20, and other gauging means 24, to engage the threads and outer surface respectively of the member being gauged (not shown), the gauging means 24 being mounted on a support 22 for movement parallel with the axis of this member, and means being provided for indicating the relative positions of the member when in its gauging position, the body 10, and the support 22. In the form shown, the member to be gauged is engaged by three equally-spaced conical grooved rolls 20, and three conical rolls 24 rotatable on a sleeve member 22 which is slidable in a part 14 of the body 10 and urged upwardly by a spring 26. This sliding movement is limited by a fixed pin 28 passing through slots in the sleeve 22 and in an abutment member 30 slidable inside the sleeve 22 and urged upwardly by a spring 32. The member to be gauged is rotated into position, whereupon its lower end depresses the member 30 according to the pitch diameters of the threaded member, and the member 22 will also be depressed, its position relative to the member 30 indicating the amount of truncation at the crests of the threads. The lead and taper of the threads can also be gauged. For indicating the relative positions of members 10, 22 and 30 a reference line 34 is provided and portions are milled off from members 22 and 30.

Abstract: 1,210,594. Cam-operated switches; retractive switches. LA TELEMECHANIQUE ELECTRIQUE. 27 March, 1968 [6 April, 1967], No. 14810/68. Heading H1N. [Also in Division B8] A safety switch 7, e.g. for stopping a conveyer belt, is operated from a distance by pulling in any direction on a cable, e.g. extending along the conveyer, whose tension is normally balanced by counterweights 4, (4<SP>1</SP>) connected to the cable ends 8 (8<SP>1</SP>) (see Fig. 3). If the cable tension is increased, counterweight 4, say, moves upwardly and a face 12 thereon pivots a weight 3 so that a face 5 thereon operates switch 7 through a thrust roller 6 (Fig. 5). Counterweight 4 is locked in the top position by a support 15. Counterweight 4 is released and allows the switch 7 to restore by pulling on a lever 16 thereon in the direction f 6 . If the cable tension is decreased, e.g. due to it breaking, counterweight 4, say, moves downwardly and its face 10 pivots weight 3 to operate the switch as before (Fig. 4). When the cable tension returns to normal, counterweight 4 returns to its normal position thus allowing the switch to restore. The cable may be pulled through a network system (18, Fig. 8) or a lever (22, Fig. 9).
