Abstract: 1417788 Optical shaft encoder GILBERT & BARKER Mfg CO 9 Nov 1973 [10 Nov 1972] 52147/73 Heading G1A In an optical shaft encoder which utilizes two photo-detectors, monitoring passage of slots in a disc coupled to the shaft, together with a bi-stable circuit arrangement, in order to prevent double counting of slots, further counting accuracy is obtained by arranging the size of the disc, the dimensions and spacings of the slots, and the dimensions of the apertures of the optical systems, in such a way that a minimum angular hysterisis is obtained for the shaft. A Formula is provided to calculate the hysteris value Ha of the disc from the known dimensions: the various dimensions of the formula being illustated in Fig. 3 and D equalling 2R. The hysteresis for the disc is given by Ha where m is the gear ratio m for the disc drive, and the preferred minimum value is 2 degrees. The arrangement is designed to avoid the effects of backlash during stop/start rotation or abrupt speed changes. As shown in Figs. 1 and 2, the sources 22, 24 may be lamps or light emitting diodes and are contained in apertures 42, 44; the detectors 26, 28 may be photo-cells or phototransistors and are contained in apertures 46, 48; they may be encapsulated in three apertures as may the output amplifiers within body 30. The circuit shown feeds a pulse counter. A modified circuit, having four lines after the flipflop, is described with reference to (Fig. 4). By the use of an exclusive OR-gate noise induced pulses may be isolated and counted and used to actuate an indicator lamp or blank out main counter display. The output of the Fig. 1 circuit can be applied to a similar circuit. Applications include a flowmeter, a mechanical computer e.g. for petrol pump dispenser.

Filed: 1964-12-24
Abstract: 1,018,770. Hydraulic coupling control. F.M.C. CORPORATION. Dec. 24, 1964, No. 52399/64. Heading F2D. [Also in Division F1] An hydraulic coupling 14 of the scoop-tube controlled type is mounted between a centrifugal pump 13 and an electric drive motor 12, the tube 28 being controlled by a linkage so arranged that the effective linear movement of the tube is reduced as the speed falls from a high to a low value. The tube control mechanism includes a pressure-responsive motor 24 with a shaft 26 carrying an arm 31 rotated counterclockwise as the pump speed and delivery pressure fall. The arm 31 carries a longitudinally adjustable block 36, a link 43 being connected to the block and to the upper end of tube 28. In the high-speed setting link 43 is approximately perpendicular to arm 31 so that the extent of movement of the tube consequent upon rotation of shaft 26 and arm 31 is at its maximum, the extent of movement being reduced as the arm moves to the low-speed position. The configuration is such that adjustment of block 36 along arm 31 has little effect on the position of tube 28 in the high-speed position, but greater effect at the low-speed position.

Abstract: 1,125,188. Corrugating tubes. GENERAL ELECTRIC CO. 28 Nov., 1966 [24 March, 1966], No. 53110/66. Heading B3E. [Also in Divisions B5 and D1] A corrugated tube is formed by placing a toothed mandrel 4 within a tube 1, against which rotating toothed dies 16, 17 are radially forced so that the dies and mandrel rotate in phase to cause the tube to deform between the die teeth and mandrel teeth. As described, the tube is forced over the mandrel (Fig. 3, not shown) and clamped thereto by wedges 26. The dies 16, 17 are angularly arranged and are initially caused to rotate in phase with the mandrel 4 by a pair of movable synchronizing gears 30, 31 which mesh with a pinion 5 connected to the mandrel 4, gear 30 being driven from the shaft of die 16. When synchronization has been achieved, the gears 30, 31 are disengaged from the pinion 5 to allow the tube and mandrel to pass therebetween. Axial pressure may be exerted on the tube end by a movable base 27. Initial synchronization may alternatively be achieved by placing a corrugated section (39), (Fig. 8, not shown) on the mandrel 4 ahead of the tube end 1. The tube may be of copper, aluminium, 90% Cu-10% Ni or other readily deformable materials.

Abstract: 1,242,684. Cigarette lighters. S.A.F.F.A. FABBRICHE FIAMMIFERI ED. AFFINI. S.p.A. 11 Nov., 1968 [9 Nov., 1967], No. 53283/68. Heading F4F. A gas-fuelled cigarette lighter has an ignition device comprising a friction wheel 7 with friction teeth 8 on an axial end face against which is pressed, by means of a spring-loaded pressure component 10, a flint 9. As shown, the spring- loading is effected by a coil spring 21 in compression between a ring 12, which is integral with component 10, and a collar 18 of precombustion chamber 13, which contains porous material and has at one end a radial bore 17 and at the other end is connected through a valve 4 to a screw-in fuel container 3. Abutting surfaces 19, 20 of collar 18 and friction wheel 7 respectively are undulating-Fig. 3- so that when wheel 7 is rotated, the resulting periodic up-and-down movement of precombustion chamber 13 against attachment 5 of valve 4 releases gas through this valve. The gas flows through precombustion chamber 13 and out through bore 17, where it is ignited by a spark. The gas flow can be increased, both by screwing container 3 into housing 1, and by pressing button 16, which forces chamber 13 down on to attachment 5, thereby opening valve 4. In another embodiment, the lighter has the external form of a propelling pencil. The pressure component may take the form of a rod with a hook at one end (Fig. 5, not shown) the hook urging the flint against the friction wheel.
