Title: Control system for a hydrodynamic torque converter
IPC: F16H61/14
Filed: 1975-11-14
Abstract: 1536657 Change - speed control SRM HYDROMEKANIK AB 14 Nov 1975 [14 Nov 1974] 49317/74 Heading F2D A lock-up clutch 14 of an hydrodynamic torque converter is controlled by a comparison of signals representing input speed 24, and engine torque demand 26 (accelerator pedal setting). Control is electronic and the input signals are represented as a function of time in a counter circuit, by frequencies, or in analogue or digital forms. Hysteresis is provided. The torque demand signal is obtained from an accelerator-controlled potentiometer. Also included is a separating clutch 16 between the converter turbine and the input to, e.g. a synchromesh change speed gear, the shift lever of which carries a clutch release switch 28. A further switch 30 prevents closure of the engine start circuit unless the separating clutch 16 is released. Two electro-hydraulic valves 18, 20 control the supply of engaging pressure to the two clutches 14, 16. Performance curves are given as is also a complete transistor circuit, Fig. 2, not shown, in which component values are specified. The following block diagrams are also included. In Figs. 2a and 2b (not shown) comparison is made between the voltage output of a throttlecontrolled potentiometer and the speedresponsive voltage derived by a converter from the speed-responsive frequency picked up at the engine ignition or by equivalent pick-up. In Fig. 2c, not shown, each pulse of an input speed responsive frequency triggers a monostable switch controlled by a throttle potentiometer which determines the pulse finish. The comparator is a flip-flop clocked by the pulses and controlling an output relay. In Fig. 2d, not shown, a throttle potentiometer (44) or capacitor controls the output frequency of a voltagecontrolled oscillator (V.C.O.) forming a phaselocked-loop with a low pass filter (50) and phase detector (48), in which latter the frequency and phase of the input speed signal (24) and V.C.O. (46) are compared, the feed back to the V.C.O. causing it to attain frequency and phase synchronization with the speed signal, whereby the output signal is speed and throttle dependent. In Fig. 2e (not shown) input speed pulses are counted in a counter (54) timed by a time base (55) to provide a digital signal for direct comparison with a digital signal derived through a converter from a throttle-angle pick-up. A microcomputer may alternatively be used.

Title: Variable-gain low-noise amplifier
IPC: H03G3/30
Filed: 1972-10-30
Abstract: 1337560 Automatic gain control THOMSONCSF 30 Oct 1972 [2 Nov 1971] 50007/72 Heading H3T In an automatic gain control circuit, signal Ie is applied to the commoned emitters of transistors Q1, Q2, which are supplied with standing current by means of a constant current D.C. source 4. An output is taken from the collector of transistor Q2, via a capacitor C, which also feeds an automatic gain control generator 10 which feeds a gain-controlling voltage to the base of transistor Q2. The change in standing current in transistor Q2 produces a voltage change across resistor R2, which is decoupled for A.C. signal by capacitor C1; this voltage change is amplified by an amplifier comprising transistors Q3, Q4 in long-tailed pair connection, resulting in a current which is fed back from the collector of transistor Q3 to the emitter of transistor Q2 to compensate for the change in standing current therein.

Title: Improvements in or relating to Variable Control Devices

IPC: H01C10/14
Filed: 1966-11-09
Abstract: 1,195,537. Electrical adjustment devices. PYE T.V.T. Ltd. 8 Nov., 1967 [9 Nov., 1966], No. 50300/66. Heading H3Q. [Also in Division H1] In a variable control device having a variable potentiometer which has a body E carrying a resistance track rotatable over a limited range by a pivoted member AC, a spindle of the variable potentiometer is rotatable to move the wiper of the potentiometer independently of the movement of the pivoted member over a greater angular range of movement covering the resistance track. Rocking movement of the control knob A causes the carrier C to rotate about a pivot D by 90 degrees between end stops. This causes the body E of the potentiometer to rotate providing limited fine adjustment whilst the spindle of the potentiometer is prevented from rotation by a friction element H which engages a wheel F connected to the spindle. Coarse control is provided over the full range of the potentiometer E by rotation of the wheel F, the body E of the potentiometer being held against rotation by a friction member G. A pointer J co-operates with a scale on the wheel F to indicate the range of fine control available. By rotating the pointer J and wheel together the body and spindle of the potentiometer remain in the same relationship to enable fine control adjustment over a different range. The potentiometer E may be used to control the iris of a television camera and a further potentiometer B may be mounted on the carrier C so as to be adjustable by rotation of the knob A. The potentiometer B may be used for black level control of the camera. A pressure operated switch may be incorporated in the control knob and a transverse quadrant motion which may include a fine and coarse control may also be provided.

Abstract: 1314843 Lighters MANSEI KOGYO KK 23 Oct 1970 [31 Oct 1969] 50485/70 Heading F4F [Also in Division H2] A piezo-electric generator for an ignition device comprises an enclosure, Fig. 1, supporting the piezo-electric element 7 together with a hammer 3 and operating member 8 which are pivotable about a pin 4, the hammer being retained away from the element by a spring-loaded pin 5 located in a slot 3a in the hammer and the ends of the pin engaging horizontal portions 2a of L-shaped slots 2 in the side-walls of the enclosure. Pressure on the member 8 loads a spring 9 located between the member and the hammer until a surface 8c on the member, disengages the pin 5 from the slot portions 2a whereupon spring 9 pivots the hammer into engagement with the element 7. A return spring 10 re-sets the hammer on release of the member 8. Alternatively, the element 7 may be arranged so that the hammer is actuated upwardly into engagement therewith and is returned by gravity. In another embodiment, Fig. 3, the enclosure 101 and operating member 108 are cylindrical, the hammer 103 and piezoelectric element 107 being arranged coaxially therein. As above, the hammer carries a pin 105 retained in L-shaped slots 102 by a spring 106. Apertures 120 in the member 108 embrace the pin and on depression of the member against a spring 104, an inclined surface 120a of the apertures 102 releases the pin 105 from portions 102a of slots 102. Fig. 7 shows a gas-fuelled lighter incorporating a generator similar to that shown in Fig. 1. The pin 205 of the pivoted hammer 203 is retained by spring 206 or step portions 201a formed on a chassis 201 until released therefrom by a surface 208a on the pivoted operating member 208. Prior to release of the pin 205 a further surface 208b on member 208 engages a valve operating member 223 to produce a flow of gas from a nozzle 222a.
