Patent GB-739812-A (GB)
Abstract: 739,812. Valves. ETABLISSEMENTS METTETAL SOC. A R.L. Jan. 21, 1953 [Jan. 21, 1952], No. 1736/53. Addition to 738,814. Class 135. In the safety device for gas heating-apparatus as described in the parent Specification a push button 12a returned by a spring 32, acts on a rod 11a, 31, to open the pilot burner valve 9a and on a rod 34, 35 and link 37 to actuate the butterfly throttle 23 regulating the flow of gas to the burners, the rod 35 carrying a pin 42 engaging a helical slot in a socket 40 rotatable on a boss 26. The throttle 23 is thus opened when the pilot valve is opened for lighting up and may be adjusted, when the apparatus is in operation, by rotating the socket 40. A pin 45 on the boss 26 enters a longitudinal slot 46 in a socket 33 carrying the push button and a transverse slot 44 in the socket 40 for limiting the axial and rotational movements respectively.

IPC: H05K3/32
Abstract: 782,739. Binding posts; holders for thermionic valves. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 8, 1955 (Feb. 11, 1954], No. 3983/54. Class 38 (1). [Also in Group XL (c)] The components in an electrical circuit (e.g. in a television receiver) are mounted on one side of an insulating panel carrying a large number of connectors to which the components are connected and the circuit is completed by wiring between the connectors arranged on the other side of the panel, the connectors being so positioned as to leave unobstructed straight paths between those connectors which are connected together by the wiring and the wiring being effected by bare conductors following these paths. Fig. 1 shows a television receiver comprising a panel 10 of insulating material upon which the circuit is mounted. Apertures 11 formed in the panel 10 support the connectors 12; these carry components such as that shown, as 20 and an I.F. transformer 23 on one side of the panel and are interconnected by wiring 18 on the other. Fig. 3 shows a fragment of the panel 10 ; a connector 12 of conical form 'is held within the square aperture 11 by lugs 13 and 14. The apex or tip of the connector is slit so that a wire may be pushed through the tip of the connector and gripped thereby. The wiring 18, on the underside of the panel 10, as shown in Fig. 3, is threaded through the spaces between the corners of the aperture 11  and the base of the connector 12 so as to enter the connector from its base and be led out through its tip. The wire leads of components such as 21, which are mounted on the upper surface of the panel are also threaded through the tip of the connector 12. The components and wiring may then be secured by dip-soldering. Fig. 4 shows a valve-holder constructed using connectors similar to those described. A plurality of conical connectors 12 are fitted within square apertures 11; in this case the lugs for holding the connectors in place in the apertures are not used. Each connector has an extension 26, the end portion of which is slit to form two limbs capable of gripping a valve pin. The extensions 26 are so disposed as to be capable of simultaneously receiving the pins of a valve and apertures are formed in the panel beneath the extensions 26 to accommodate the pins. A plate of insulating material having holes arranged to permit the passage of the valve pins is mounted above the connectors to hold them in position; this is attached to the panel 10 by a bolt passing through aperture 29.

Title: Electrical frequency converter
IPC: H02M7/515
Filed: 1978-06-22
Abstract: A rectifier feeds an inverter having main thyristors T1-T4 in a bridge circuit. Two trains of pulses gate bursts of oscillation from an oscillator to five pairs of thyristors in opposite arms of the bridge alternately. Each arm of the bridge is connected to a pair of anti-parallel connected quenching thyristors Ta connected to a quenching capacitor Cs. The quenching thyristors are turned on respectively by pulses derived by a differentiating circuit and a monostable circuit from the leading and trailing edges of the pulses which turn on the main thyristors in a pattern such that each main thyristor is quenched at the correct time. A protective circuit is provided to short out the d.c. voltage between the rectifier and the inverter when a short circuit is sensed (Figure 1 not shown). <IMAGE>

Title: Electronic pipe organ
IPC: G10H1/00
Filed: 1978-08-10
Abstract: A pipe organ having unlimited possibilities of coupling any desired rank of pipes to any desired console keyboard, as compared with conventional pipe organs. This selective coupling is accomplished by multiplexed transmission of impulses from keyboards and stops, which impulses are fed in parallel into a shift register circuit converting the parallel impulses into series form, transmitting them in this form via a sender and a receiver to a stop decoder and then to a further shift register circuit converting them from series form to parallel form, to be transmitted in this form to the selected pipes. An advantage is that the transmission in series form only requires a few lines. <IMAGE>

Title: Parallel analog-to-digital converter
IPC: H03M1/36
Filed: 1979-01-05
Abstract: An analog signal is converted into an n bit digital signal (B1, B2, B3) by n comparator circuits (C1, C2, C3) which compare the analog input to 2<n>-1 reference inputs (A1-A7). Each comparator output alternates as the analog signal increases through the reference levels, logic circuitry including n-1 exclusive- OR gates (34, 38) decoding the comparator outputs into the n bit code. The comparator circuit C3 for comparing the analog input signal VIN with each of reference levels A1, A3, A5 and A7 and providing an alternating output comprises pairs of differential input transistors Q1 and Q2, Q4 and Q5 etc. and current sink transistors Q3, Q6 etc. associated with the reference levels. The collectors of the differential transistor pairs are cross coupled to two output resistors R9, R10 which are connected to a differential exclusive-OR gate 38. A latching circuit Q18, Q19 is operable to latch the comparator output when the comparator is in other than the comparing mode. <IMAGE>

Title: Built-in test circuit for antiskid system
IPC: G01R31/00
Filed: 1980-04-01
Abstract: A circuit incorporated with an antiskid system for testing the operability of the system. A multivibrator (42) may be actuated to energise converter circuitry (46) with a signal indicative of a particular wheel speed. The entire antiskid system is then caused to function as though the vehicle wheels are actually spinning and the vehicle is moving. The major subcircuits of the antiskid system are connected to logic circuitry (28, 30, 32, 34, 72, 74, 56, 20, 18, 16, 24) which senses their operation and produces an output signal to a lamp (12) which is illuminated when the subcircuits are properly operative. When the multivibrator operation is ceased, changes in operation of the various subcircuits is again sensed by the logic circuitry which, if such subcircuits are operating properly, deenergises the lamp (12). <IMAGE>

Title: Motor power control circuitry
IPC: H02J3/18
Filed: 1981-04-10
Abstract: To control the power supplied to a three-phase induction motor as a function of the motor load, the primary winding of a current transformer T1, T2, T3 is included in each phase input line to sense the phase currents, and the three line- to-line voltages are sensed by voltage transformers. Square waves in phase with the sensed currents and voltages are summed at a point S4 in a circuit producing firing signals FIRE A, FIRE B and FIRE C for controlling triacs connected respectively in series with the current transformer primary windings. The signal at S4 is integrated by an operational amplifier A4 and the integration signal supplied to three differential amplifiers A5, A6, A7. The voltage square waves VsA, VsB and VsC are also used to produce sawtooth signals RAMP A, RAMP B and RAMP C with a repetition rate of twice mains frequency which are respectively summed with the integration signal at inputs of the differential amplifiers A5, A6, A7. The FIRE A, FIRE B and FIRE C signals are applied to blocking oscillators for controlling the triacs. The conduction angles of the triacs are thus controlled in dependence upon motor load. <IMAGE>
