Title: Improvements in or relating to electric storage batteries
IPC: B22D25/04
Filed: 1964-10-23
Abstract: 1,112,085. Batteries. OLDHAM & SON Ltd., and H. K. BARTON. 18 Oct., 1965 [23 Oct., 1964], No. 43394/64. Heading H1B.

Title: Electronic musical instrument
IPC: G10H1/055
Filed: 1968-09-12
Abstract: 1,203,162. Electrophonic musical instruments. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 12 Sept., 1968 [15 Sept., 1967], No. 43403/68. Heading G5J. In a keyed electronic musical instrument comprising a plurality of tone generators each coupled to an output via an individual gate, each key being adapted to charge a capacitance to a voltage which increases with the strength of actuation of the key, and the capacitance voltage being fed to an actuating terminal of a gate for unblocking the gate to an extent which increases with the magnitude of the voltage, the difficulty arises that if the discharge time of each capacitance is short the tone decays too rapidly whilst if it is long the note cannot be repeated soon after a strong actuation. This is avoided by making the capacitance discharge rapidly at first and more slowly thereafter. In Fig. 2a the capacitance comprises two capacitors C1 and C2 in series each charged through a respective diode by voltage induced in associated coils S1 and S2 when the key moves the magnets M1 and M2. The initial discharge is mainly of C2 through R2 and takes 0À1-0À2 seconds; the next stage of the discharge is of C1 through D3 and R1 and has a time constant of two to four times the initial value; finally when the diode D3 cuts off, the discharge is through the load R and has an even longer time constant. In a modification (Fig. 3, not shown) the components S2, D2, C2 and R2 are omitted, and in another modification (Fig. 4a, not shown) the capacitor C2 is omitted; in this latter case the resistance (R S ) in series with D2 should have a value of about five times the critical damping resistance of the circuit comprising the coils, the capacitor and the resistance.

Title: Improvements in or relating to radio phase-comparision receivers
Inventor: BARNARD CHARLES REGINALD NOWEL
IPC: G01S3/14
Filed: 1962-11-16
Abstract: 997, 708. Phase measurement. MINISTRY OF AVIATION. Nov. 14, 1963 [Nov. 16, 1962], No. 43410/62. Heading G1U. [Also in Divisions H3 and H4] A phase comparison receiver comprises an adding circuit to which a received signal is applied, means for deriving a locally generated signal at the same frequency as the received signal and for periodically changing its phase in steps, means for applying the stepped phase signal to the adding circuit and for amplifying and detecting the output signal thereof and means for connecting the detected output via a separate diode gate circuit during each step period to means providing an indication of the phase difference between the received and locally generated signals; the indication may also be used to ring the phase of the locally generated signal into a constant phase relationship to the received signal. A signal derived from a high stability oscillator 1 via a divider 2 locks the phase of an oscillator 3 which operates at the same frequency as a signal received via aerial 18. The oscillator output is applied to a phase shifting circuit 4 and phase inverters 8 and 9 whereby a reference signal and signals shifted in phase by 90, 180 and 270 degrees therefrom are obtained and applied respectively to the inputs of diode gates D1-D4. The output signal from divider 2 is also applied to a switching waveform generator 11 which provides a switching signal output which energizes lines 26- 29 and lines 12-41 in sequence. Diode,gates D1-D4 are thus opened in turn to supply a signal which is stopped in phase to a primary winding 16 of a transformer 17 in which the signal is added to the received signal applied to primary winding 19. The resultant signal, which has an amplitude which is a function of the phase difference of the signals applied to the transformer, is applied via a conventional receiver circuit and a squaring detector 25 to the common input of four diode gates which are switched via lines 26-29 by the output signal of the switching waveform generator 11. The outputs of the separate gates are applied via smoothing circuits to a meter 32 which indicates the phase difference between the received signal and the locally generated reference. In a second arrangement (Fig. 3, not shown) in which a variable phase shifter is connected between the phase locked oscillator 3 and the input diode gates, the phase difference indicating means also controls the adjustment of the phase shifter to bring the phase of the reference signal and the received signal into a fixed relationship. Specification 673,050 is referred to.

Title: Power control circuit
IPC: G05F1/455
Filed: 1965-10-15
Abstract: 1,120,637. Control systems for consuming apparatus; rectifying. GENERAL ELECTRIC CO. 15 Oct., 1965 [18 Nov., 1964], No. 43714/65. Headings H2F and H2H. [Also in Division H3] Power is switched to a load through a seriesconnected three-terminal bidirectionally conducting semi-conductor device which is fired by a signal on its gate derived from an energy storage means through another bidirectionally conducting semi-conductor device. In Fig. 3 a capacitor 55 charges up from an A.C. supply 35, 45 until its voltage is sufficient to break down a bidirectional diode 57, when current flows into the gate of a bidirectional triode 33 to turn it on. Current than passes from the source through the load 43 and a saturable reactor 41. The change in voltage at 39 causes an LC circuit 47, 49 to ring and when the reactor 41 is saturated the voltage across the triode 33 is reversed to turn it off. This operation may occur several times in each half-cycle of the supply. The circuit of Fig. 4 (not shown) fires only once during each half-cycle as the triode 33 has no ringing circuit to turn it off and is extinguished when the A.C. supply voltage reverses. Operation is controlled by a transistor (77) which when turned on by a voltage (at 83) shunts the capacitor (61) through a diode bridge (69, 71, 73, 75) and prevents it from charging. In a modification of this (Fig. 5, not shown) the transistor (99) is turned on and off by pulses at a frequency higher than that of the supply. The capacitor then charges in steps through the diode bridge until its voltage is high enough to fire the bidirectionally conducting devices. In another circuit (Fig. 6) the capacitor 113 is charged in alternate half-cycles through diodes 104 and 111, but as resistors 117 and 119 are unequal in value the capacitor voltage is greater in one half-cycle than the other and the bidirectionally conducting devices fire only once per cycle to pass D.C. through the load. Fig. 8 shows a snap-action circuit firing once per cycle, using a double Zener diode 137 in series with a D.C. control voltage applied at 150 so that the capacitor 133 is charged to a voltage which is the algebraic sum of the Zener voltage and the control voltage. Reversal of the polarity of the control voltage causes the bidirectionally conductive devices to fire on the other half-cycle.

Abstract: 1,156,555. Casting processes. AMSTED INDUSTRIES Inc. 30 Sept., 1966 [14 Oct., 1965], No. 43790/66. Heading B3F. In a method of successively bottom pressure pouring moulds 10 from a tank 16, the weight of a ladle (30) (Fig. 2, not shown) and the molten metal (34) contained therein is ascertained from load cells (32) contained in the air pressurized tank 16 from which weight the volume of the molten metal is calculated, the aggregate volume of the moulds 10 are then determined and adjustment is made to at least one of the moulds 10 to render the said aggregate volume to at least 85% of the volume of the molten metal. The mould 10 may be adjusted in volume by positioning the rear end block (58) (Fig. 3, not shown) of the mould by a poweroperated piston-rod (68). The moulds 10 are movable along tracks 14 until their pouring gates (22) are aligned with the pouring tube (22) of the tank 16. A jack 24 raises the rear end of the mould to lower the pouring gate on to an air sealing tube cap 40 and air pressure is raised in the tank 16 to pour the molten metal into the mould.
