Patent GB-414039-A (GB)
Abstract: 414,039. Knitting-machines. BENTLEY, P. A., GODDARD, J. H., and DEANS, F. E., Komet Works, New Bridge Street, Leicester. Dec. 20, 1932, No. 36127. [Class 74 (ii).] For the production of splicing and patterning effects or for changing the circumferential position of the join when putting in stripes a supplementary automatic control is used to vary, for example, the distribution of yarns at a given part of the knitted tube. The normal control 52 operates the supplementary control means to adjust the yarn feed &c. cams for co-operation with needles for the knee or front part or, alternatively, the foot bottom or rear part of a stocking &c. The splicing yarn feeder is controlled by a cam or cams mounted on a sleeve 18 loose on a shaft 10. To adjust the cams to vary the timing of the yarn feed in relation to the shaft 10, the sleeve 18 is connected to its shaft by a ratchet clutch 20 the pawls 26, 28 for which can be put out of action by a cam 62 on a striking lever 44 operated by the drum 52. If the sleeve 18 runs on when the driving connection between it and the shaft 10 is broken it is stopped by a projection 66 thereon engaging the end 64 of the lever 44. The sleeve is eventually coupled to the shaft at 180‹ from its former position. The pawls 26, 28 are carried by an arm 36 which can be adjusted on the shaft 10 to bring the splicing feed into action at any desired needle for knee splicing. The corresponding adjustment for foot bottom splicing is obtained independently. The cams 48, 50 and the parts controlled thereby first adjust the sleeve 18 relative to the shaft 10, according to which side of the hose is to be spliced and then the cams on the sleeve are rendered effective by their followers 13, 15, 17 being placed in operative relation by the cams 25, 27. The splicing cams are made in three parts, while the associated cams for operating the trapper &c. and adjusting the stitch are made in two parts each. By shogging the sleeve 18 it is possible to control the splicing cam follower 13 from two different sets of cams while the associated followers 15 and 17 are being controlled by one set each. Specifications 280,612, 301,350, 337,058, [all in Class 74 (ii)], and 380,092 are referred to.

Title: Automatic tint control circuits for colour television receivers

Filed: 1971-09-13
Abstract: 1330387 Colour television SONY CORP 13 Sept 1971 [25 Sept 1970] 42578/71 Heading H4F A tint control circuit for a chrominance signal whose phase and amplitude represent hue and saturation comprises a circuit producing a phasecorrecting signal when the phase is in a limited angular range (e.g. a 20 degree range of flesh tones) and an amplitude-sensitive circuit controlling the phase correction, for example so as to effect correction only when the saturation is below 30%. The arrangement is thus designed to improve flesh tones without affecting the hue of other picture areas having higher saturation values. As shown the chrominance signal is amplified at 15 and passes to a circuit 16 where its peak portion only is selected and passed to a wave shaper 23. Here the differential action of transformer 26 produces at the peak times of the input signal the outputs shown applied to differential amplifier 27, 28. If these occur at the times represented by the output of reference circuit 31 then a zero signal will be supplied to adder transformer 37, but if the phase is in error by an amount not exceeding a certain angle (dependent on the width of the peak signal produced by 16) then a correction signal will be added to the chrominance signal supplied to the transformer secondary direct from the emitter of 15, this correction signal being of such phase as to correct towards the reference phase. The reference oscillator is adjusted at 35 to produce a flesh-tone output, and becomes disabled at high saturation levels when the emitter potential of 17 rises, and diode 40 conducts to reversebias 36.

Title: Control of the composition of exhaust gases of internal combustion engines
IPC: F02M7/00
Filed: 1973-09-13
Abstract: 1449221 Automatic control of exhaust gases ROBERT BOSCH GmbH 13 Sept 1973 [14 Sept 1972] 43063/73 Heading G3R A control circuit for the fuel supply of an I.C. engine is responsive to the output of an exhaust gas probe after a time during which the engine operating conditions remain constant and the probe output has reached the measured value. The probe may be exposed to the exhaust gas intermittently or continuously depending on the materials used in its construction. The circuit shown is designed to operate when the engine is idling as signalled by a switch 12 as well as speed sensor 13 and switch 9. A temperature sensor 11 ensures that the engine is at its normal operating temperature and prevents operation of the circuit during starting. The ignition switch 14 and differentiating circuit 25, 24 supplies pulses to reset bi-stable stages 21, 28. In operation when the engine is hot the bi-stable 21 is set to apply a signal to the first input of AND gate 22. When idling is sensed then the other inputs of AND gate 22 are energized and monostable 23 is upset to apply 0 and I signals to gate 29 and bi-stable 28 respectively and the latter switches to its set state and puts a 1 signal on AND gate 29. After a predetermined time monostable 23 relapses and provides a 1 signal to AND gate 29 which now conducts and upsets monostable 32 to enable gate 34 or 35 and allow the output of comparator 36 to energize motor 38 to adjust the fuel supply device, injection pump or carburetter, for the engine. The change in fuel is in a direction to bring the composition of the exhaust gas measured by probe 15 into agreement with a predetermined value. If during the upset period of monostable 23 the idling switch 12 is opened the bi-stable 28 is disabled and prevents operation of monostable 32. The second output of monostable 32 disables the bi-stable 21 until the next ignition switch signal. In a modification, Fig. 4 (not shown), the monostable 32 is replaced by a bi-stable circuit (40) which enables the gates in the fuel adjustment circuit on the relapse of monostable 23 but remains in this state until reset by the opening of the idling switch or the comparator 36 output changing state when the desired value is achieved.

Abstract: 916,299. Automatic circuit-breakers. CRABTREE & CO. Ltd., J. A. May 25, 1960 [April 2, 1960], No. 43802/61. Divided out of 905,639. Class 38 (5). In a moulded-case circuit-breaker having overload-responsive electromagnetically-tripped mechanism, such as that of Specification 905,639, the magnet frame is reduced in crosssectional area in the vicinity of the armature to provide an additional shortened path of high reluctance to ensure operation under shortcircuit conditions. In the circuit-breaker shown, overload current through the coil 16 causes a magnetic plunger 6 to be pulled towards a polepiece 18 with a time delay. An air gap 15x between the polepiece 18 and the end of the magnet frame 13 ensures that the flux produced by the coil 16 passes through a path provided by the plunger 6, the polepiece 18, the armature 15, the frame 13 and a sleeve 12 causing the armature to be attracted and the circuitbreaker to be tripped. The frame 13 is provided with a hole 13x to produce a highreluctance portion so that when a short-circuit occurs and instantaneous tripping is required a shortened flux path exists from the reduced end of the plunger 6 (in the position shown) across to the portion of the frame 13 between the hole 13x and the gap 15x, thence to the armature 15, the frame 13 and the sleeve 12, so that the armature 15 is attracted to cause tripping of the circuit - breaker.
