Title: Improvements in and relating to the employment of thermionic valve circuits
IPC: H04L27/06
Filed: 1924-07-22
Abstract: 243,407. Brydon, S., and Fletcher, D. B. July 22, 1924. Thermionic amplifiers and detectors. - A back coupled valve is set at the " threshold " point withou appreciable backlash, so that it generates high-frequency oscillations contem porary with the incoming signals, the corresponding anode voltage-variations being applied to the grid and filament of a second valve, which contains a detecting or recording device in its plate circuit. The invention is distinguished from known arrangements which utilize changes in the value of direct, current in the anode circuit of a triggered valve, and from the super-regenerative circuits described in Specification 182,135. The first valve A is coupled through a condenser O, shunted by a resistance q, to the valve B which feeds a recording device R or a pair of phones. The proper setting of the valve A on the threshold point is ascertained by varying the filament current and the coupling between the coils m and g against a step-by-step adjustment of a grid potentiometer h, i. The curve X, Fig. 2, represents the " oscillation " conditions, whilst Y corresponds to the cessation of oscillations, the distance between these curves indicating the degree of back lash present. For telephony reception the valve should be set near the converging point Z, whereas for Morse reception a certain amount of back lash is desirable as providing an impulsive effect, disproportionate to the signal voltage, in the recorder R. The frequency of the oscillations generated by the valve A is determined by the tuning of the circuit g, and may differ from that of the received signals.

Title: Explosively actuated fastener driving tool
IPC: B25C1/10
Filed: 1965-04-26
Abstract: 1,030,978. Cartridge-actuated tools. JAPAN DRIVE-IT CO. Ltd. April 26, 1965 [April 27, 1964], No. 17556/65. Heading B4C. A cartridge-actuated tool for driving fasteners such as studs or pins into a wall comprises a cartridge-receiving plug 33 slidable within a barrel 32 and cylindrical members 27, 6 having projections 66, 67 respectively for co-operation with projections 62, Fig. 4 (not shown), on the barrel such that when the projections are disengaged the barrel can be moved towards or away from the cartridge receiving plug and when the projections are engaged the barrel is locked against such movement. The rear cylindrical member 6 is slidably mounted in a housing 2 and has secured therein a guide 7 for a firing pin 10 loaded by a spring 12 and normally retained in the position shown by a locking piece 15. The front cylindrical member 27 is mounted in a housing 26 and when the tool is closed as shown, abuts the rear cylindrical member and is connected therewith by the interlocking projections 62 on the barrel. In operation, in order to load a cartridge in the tool, the housing 26 is moved forwardly against the action of a spring 29, the barrel turned through 45 degrees to disengage the projections and pulled forwardly, and then the barrel assembly pivoted about a pin 3 to the open position ; during the pivoting action an ejector 38 ejects the previously spent cartridge. The new cartridge is then inserted and the above procedure reversed. To fire the cartridge the end of the barrel is pressed against a workpiece, thereby causing both cylindrical membors to move rearwardly and so load the firing pin. To release the firing pin a trigger 23 is moved which abuts a rocker arm and causes a pawl 20 on the latter to move the locking piece 15 and release the pin. In order to vary the force of the explosion, the space 34 below the cartridge chamber 35 is decreased or increased by releasing a catch 58 from a slot 57 in the barrel and rotating the latter so that different projections 62 on the barrel engage with those on the cylindrical member. A sub-barrel 43 is connected to the front end of the main barrel by means of a collar 44 having a weakened portion 52 so that if the plunger 47 strikes the end of the barrel with excessive force the collar breaks.

Abstract: 910,812. Automatic voltage control; alternators. MULLARD Ltd. May 16, 1961, No. 17795/61. Classes 35 and 38 (4). In a compound field excitation arrangement for a rotary generator, a cycling switch connected across a compounding source intermittently bleeds excitation current over a part of the load current range of the generator up to a predetermined short-circuit current, the duty-cycle of the switch being varied in dependence upon the value of the load current. In an embodiment, Fig. 8, a field 5 of a rotary generator is supplied by a voltage dependent source S 1 , not shown, and a compounding source S 2 . An intermittent bleed through a silicon controlled rectifier 21 is made by a pulse at fixed intervals from a unit 39 synchronized to a square-wave oscillator 30. The rectifier 21 is switched off by silicon controlled rectifiers 23, 24 rendered conducting by timing pulses applied in sequence. The rectifier 23 is made conductive simultaneously with the rectifier 21 by a pulse from unit 39. A commutating condenser is discharged by the rectifier 24 after a delay, determined by a signal from a magnetic amplifier MA or a delay unit 36 through an " OR " circuit 34 and pulse control 37. The magnetic amplifier MA is energized with a square-wave signal from the oscillator 30 and has a control winding 27 energized in dependence on the current-bleed and a reference winding 28 energized from a battery 29, to produce a square wave of double the oscillator frequency having a delay dependent on the current in the control winding. 27. A signal from the oscillator 30 is also fed to a monostable trigger multivibrator 36 acting as a time delay. The time-delayed signal and the signal from the magnetic amplifier are fed to the "OR"  circuit whereby the first arriving pulse controls the firing time of the rectifier 24. In another embodiment, Fig. 10, for an alternator 1, a voltage-dependent excitation current is derived by a device S and fed to a field winding 5 and a compounding excitation current is fed to the field winding from a current transformer 6 through a full-wave rectifier S2.

Abstract: 884,366. Protective arrangements. REYROLLE & CO. Ltd., A. May 30, 1958 [June 5, 1957], No. 17883/57. Class 38 (5). [Also in Group XL (c)] A transistor relay circuit suitable for a protective arrangement comprises a bridge having a supply voltage connected across one diagonal and a relay connected across the other, one arm of the bridge being constituted by a non-linear impedance and an adjacent arm by the collector circuit of a transistor whose emitter circuit constitutes the control circuit for the relay. The Figure shows a protective arrangement comprising relay A connected across one diagonal of a normally balanced bridge constituted by resistors D and D<SP>1</SP>, a non-linear resistor C and the collector-base path of a transistor B, the supply voltage for the bridge being provided by a full wave rectifier E2. The emitter-base circuit of the transistor is connected to a core balance leakage current detecting transformer F associated with the trailing cable of a machine in a coal mine. The transformer is connected to a full wave rectifier G, G<SP>1</SP> circuit so that if the leakage current exceeds a predetermined value sufficient current is supplied to the emitter circuit of the transistor to cause the relay to operate. Excess emitter current is prevented by arranging for the transformer to saturate and by providing a non-linear resistor H constituted by a rectifier in shunt with the input circuit. The non-linear bridge resistor C has the same temperature characteristics as the transistor and the linear resistor D<SP>1</SP> has such a value that the voltage across the non-linear resistor C remains substantially constant with the supply voltage variations. In an alternative circuit (Fig. 3, not shown), the relay circuit is used in a remote control arrangement, the emitter circuit being connected in series with a rectified A.C. voltage supply and a switch located at a remote point.
