Title: Improvements in or relating to clutch mechanisms
IPC: F16D45/00
Filed: 1960-11-08
Abstract: 921,173. Clutch combinations. REGIE NATIONALE DES USINES RENAULT. Nov. 8, 1960 [Nov. 17, 1959], No. 38376/60. Addition to 834,755. Class 80 (2). The clutch mechanism shown in Fig. 1 of the parent Specification is modified by the disengaging spring 31 of the centrifugal clutch acting on the auxiliary plate 19 instead of on the plate 12, and by some of the springs 20 (three out of six as particularly described) instead of acting directly on the plate 18 of the disconnecting clutch, act on a flange 32<SP>3</SP> of a push member, the flange being countersunk in the plate 18 and a portion 32<SP>1</SP> of the push member extending through a bore in the plate and contacting the auxiliary plate 19. The disc 23<SP>1</SP> of the disconnecting clutch is of reduced diameter compared with disc 22 of the centrifugal clutch to allow the passage of the push members. The portion 32<SP>1</SP> is of such a length that when the flange 32<SP>3</SP> seats on the bottom of the recess in the plate 18 the disc 23<SP>1</SP> of the disengaging clutch is released. Thus, when the clutches are engaged the clamping pressure on the disc 22 is due to all the springs 20 and the pressure on disc 23<SP>1</SP> is that due to the springs 20 which act directly on the plate 18.

Filed: 1970-08-14
Abstract: 1328534 Automatic focusing CANON KK 14 Aug 1970 [20 Aug 1969] 39312/70 Heading H4D  In an automatic focusing system, two beams of light A, B, Fig. 1, from the object to be focused, are alternately directed, by means of shutter disc 1, and via optical wedge 2, to a photodetector 3. The alternating outputs of the detector 3 are fed, via amplifier 4 and noise reduction filter 5, to a switch 6 operating in synchronism with the disc 1 such that signals due to beam A are fed to one input of differential amplifier 7 and signals due to beam B are fed to the second input of the differential amplifier, the output of amplifier 7 being zero when the two beams are equal whereby this is used as a criteria for focusing. The amplifier output is thus used to adjust the position of the focusing lens, and also that of the wedge 2 as shown, or the detector 3 (Fig. 2). A source of light P, Fig. 4, laterally offset from the focusing lens F may be mechanically coupled to the lens such that when a beam of light from the source evenly illuminates the object to be focused, the lens is correctly adjusted for focusing. The beams A and B are produced in Fig. 4 by apertures in a diaphragm 70.

Abstract: 1,091,588. Laminates. TOYOBO CO. Ltd. Sept. 22, 1965 [Sept. 22, 1964], No. 40505/65. Heading B5N. Strip or tape-form laminates having curled longitudinal edges are made by bonding to a tape of synthetic resin a film or coated layer, which may be much thinner, of a synthetic resin of different chemical or physical properties (which latter includes a different degree of orientation or stretching), and stretching the laminate, with or without heating. Synthetic resins usable are nylon 6, nylon 6, 6, nylon 6, 11 polyesters such as polyethylene terephthalate and tereisophthalate, polyolefins such as polythene, ethylene/propylene copolymers, polypropylene and crystalline and isotactic polypropylene, polystyrene, P.V.C., polyvinyl alcohol, polyvinylidene chloride, polyacrylonitrile, polyethers, polycarbonates, polyurethanes, polymethacrylates, and mixtures, copolymers, and acetylated and chlorinated derivatives thereof. The product exemplified is a laminate of polypropylene film bonded, by chlorinated polypropylene, to a polypropylene film which has been biaxially stretched to six times; this laminate curls towards the biaxially stretched layer on being slit into tapes and stretched 70% at 30 C. A number of such laminates may be united, by longitudinal line-bonding, in various arrangements, or may be line-bonded to a base film, the bonded materials so formed, on being stretched, producing strip-form products having components which are longitudinally curled, or of oval or dumb-bell section, due to curling of the component laminates. The drawings (not shown) illustrate typical products in section. The line bonding of the component laminates may be effected by adhesive, heat, or ultrasonics or they may be stitched together. Some of the strips may be slit longitudinally (e.g. Figs. 6c, 9c, not shown). The strips may be used decoratively, may be twisted into cords or strings, or cords or wires may be laid on the laminates before stretching, being thereby enveloped, or permanently sheathed, in the convolutions formed. Uses of the products of the invention mentioned are tyre cords, wrappers, and materials for rugs, wall coverings, and clothes.

Title: Engine starting control system
IPC: F02D29/02
Filed: 1974-09-18
Abstract: 1479967 Starting prime movers AUTOMATIC SWITCH CO 18 Sept 1974 [12 Nov 1973] 40621/74 Heading H2H In an engine starting system, a solid state counter 67 is arranged to provide a plurality of pulses for closing and opening a starter solenoid a plurality of times so as to periodically crank the engine and means responsive to a predetermined number of said pulses for terminating the output of pulses from the counter and hence terminating engine cranking. Fig. 1 (not shown) depicts a block diagram including a manual starting button and fault detecting devices. When the manual starting button is operated, power is supplied via transistor 56 to a silicon controlled switch 62 or programmable unijunction transistor PUT which presets the counter 67 for a count of four. A further PUT 80 is arranged to supply pulses along line 79 to counter 67. After a predetermined number of such pulses, a pulse is fed on line 66 to energize a crank drive circuit (Fig. 2, not shown) comprising a relay operated by a pair of transistors and arranged to control the starter solenoid. After four attempts to start the engine, the signal on the counter output line 76, 77, 78 will be such as to turn on transistor 90 the output of which is fed via a fault circuit 25 so as to turn off transistor, 109 and 56 and so inhibit further cranking. When the engine starts, a signal from speed switch 100 charges capacitor 103 which turns on transistor 106 so as to turn off transistors 109 and 56 so as to inhibit further cranking. When the engine is stopped, the signal from the speed switch disappears and capacitor 103 discharges over a predetermined period via constant current diode 104 so as to maintain transistor 106 conductive for the predetermined period and thus inhibit further cranking for that period. Fig. 6 (not shown) depicts a block diagram of a counter 67 which comprises four flip-flops in cascade. Figs. 1 and 5 (not shown) relate to circuits using controlled rectifiers which turn off the fuel control valve in the event of low oil pressure, high water temperature or excessive speed.
