Nov. 16, 1933, No. 32004. Convention date, Nov. 16, 1932. [Class 38 (ii)] In a device for converting direct current to polyphase comprising an inductive network and a group of valves rendered conductive in order, the network is provided with a second set of terminals connected to the direct current circuit through a second set of valves in such a way that a current can circulate through portions of the network and the direct-current circuit, the object being to ensure that under varying conditions of load there shall be sufficient potential difference across the condensers which serve to render the valves of the first set conductive. The direct-current circuit 10 is connected to the polyphase circuit 11 and the terminals of the windings 13, 14, 15 of the inductive network through valves 16 ... 21, the grids of which are energized from a polyphase circuit 40 of the required frequency. As the current shifts from grid to grid the valves are rendered conductive and cut-out by the action of condensers 32, 33, 34 connected across the terminals of the windings 13, 14, 15. The windings 13, 14, 15 are continued past the neutral point as windings 131, 14<1>, 15<1> having tapping terminals which are connected to the direct-current circuit by valves 22 ... 27 arranged as shown, so that when, e.g. the valve 16 is conducting, a current can circulate through the valve 16, the windings 13, 13<1>, the valve 22 and a portion of the direct-current circuit 11.

Title: Fluid-actuated clutches
IPC: F16D31/02
Filed: 1932-11-15
Abstract: 405,429. Clutches. RILEY, P., Castle Works, Aldbourne Road, Coventry. Nov. 15, 1932, No. 32276. [Class 80 (ii).] Members 11, 15 are adapted to be clutched together by one or more pistons 20 slidable longitudinally in the member 11 and cooperating with a cam surface on the member 15, the piston or pistons being operated from a source of fluid pressure introduced on the opening of a control valve. As shown, a gear wheel 11 is loosely mounted on a shaft 12 between members 15, 21 secured thereto. There are eight pistons in the member 11 and the cam surface has two crests 16 and two hollows 17. Pressure oil is supplied, under the control of a main valve, through a duct 23 in the shaft and radial passages 27 to two diametrically-opposed arcuate grooves 24 in the face of the member 21. When the main valve is opened, oil passes into the two piston chambers 19 which at the moment have their inlet openings 25 in register with the grooves 24. The corresponding pistons 20 are thus forced against the hollows 17 and frictionally take up the drive. When, during slip, the openings 25 pass out of register with the grooves 24, oil is trapped in the chambers 19 and the pistons engage the rising faces 18 of the cam surface, and a substantially solid drive results. As leakage occurs, further slip is produced and succeeding pistons take up the drive. On release of the oil pressure, spring-loaded valves 29, which control communication between outlets 28 and arcuate grooves 24<1> on the face of the member 21 and which are normally closed by the oil pressure acting through radial passages 22, open, thus releasing the trapped oil. In a modification, the valves 29 are replaced by spring-loaded balls 30, Fig. 5, adapted to be positively depressed by a flange 32 on a slidable sleeve 31. The clutch may be employed in the gear-boxes of motor-vehicles or as a tail clutch therefor.

Abstract: 775,743. Releasable fastenings. P.S.C. EQUIPMENT, Ltd. Sept. 12, 1955 [Nov. 10, 1954], No. 32544/54. Class 44. [Also in Group X] A device for clamping around metal wire or rod to provide a temporary anchorage thereon comprises a body 1 adapted for location around the metal wire or rod, a tapered recess 2 arranged longitudinally in said body through which the metal wire or rod extends, and jaws 5 within the recess, each said jaw having a longitudinally extending tapered inner and outer surface 6, 7, the said inner tapered surfaces 7 forming together a tapered bore for the accommodation of a sleeve 13 surrounding the portion of the metal wire or rod extending through the tapered bore, the inner and outer tapered surfaces of the jaws and the tapered recess in the body co-operating to clamp the sleeve in gripping engagement with the metal wire or rod upon relative axial movement therebetween. As shown in Fig. 2, the jaws are forced into the body 1 to clamp the sleeve 13 on to the wire, rod or the like by means of a cap nut 8 which is screwed on to the body. The sleeve is internally serrated and is provided with a plurality of longitudinal slits 14 equally spaced from one another, each slit extending from the small diameter end of the sleeve and terminating at a peripheral groove 15 spaced from the opposite end of the sleeve. To assist in locating the sleeve in the tapered bore a key can be used having a tubular shank with wings at one end which can be grasped to turn the key. The key shank is externally threaded and is adapted to be screwed into a thread provided in the bore of the cap nut after the key is threaded over the wire, rod or the like. When the key is screwed into the cap nut its end engages the sleeve to displace it axially inwardly on the tapered bore. In a modified construction, Fig. 6, a split sleeve is used which consists of two separate portions 22, each portion being connected by means of a shank 32 to a lever 25 which is connected by means of a pair of links 27, a pivot pin 28 and a stud 29 to the body 1. By moving the lever 25 the portions of the sleeve can be moved into or out of the tapered bore in the jaws 5. In this construction the jaws 5 are urged into the tapered recess 2 by means of a spring 18 trapped between the jaws and the cap nut 8. Specification 764,197, [Group X], is referred to.

Title: Optical stabilizer
IPC: G05D3/14
Filed: 1973-07-09
Abstract: 1442773 Automatic control OPTICAL RESEARCH & DEVELOPMENT CORP 9 July 1973 32597/73 Heading G3N [Also in Division H4] In an optical device for observing an object ( a telescope) subject to accidental motion (e.g. hand held) one of the elements (a mirror B) is angularly movable relative to the optical axis 16 and its deviations are detected by sensors whose signals control means for adjusting a restoring force, the restoring force being varied in proportion to the time averaged angular displacement. The arrangement is such that small, rapid movements are compensated by the inertia of the mirror while the invention causes the mirror to follow up slower movements. The mirror is suspended by an axial filament and is immersed in a damping fluid. As shown the sensors comprise "metal detectors" 27, 29 which co-operate with a metallic ring 25 on the back of the mirror. They are oscillators arranged to give a D.C. output whose polarity depends upon the direction of the displacement and zero output for no displacement. The signals control motor driven potentiometers 40, 60 which adjust the current through electromagnet coils 50, 70 whose fields react with a permanent magnet J on the back of the mirror. Stiction in gearing between motors and potentiometers provides a dead band. It is stated that the electro and permanent magnets may be interchanged. In one alternative embodiment, Fig. 4, (not shown) the motors rotate permanent magnets in a gap in each yoke K, L to vary the strength of the resulting field; this replaces the electromagnets. In another embodiment, Fig. 3, (not shown) the sensors are photo-electric devices in a bridge circuit and receive light from a solid state source reflected from a mirror attached to the back of the permanent magnet J. Control is effected as in Fig. 2 except that the output of the bridge is connected through separately adjustable proportional, differential and integrator networks. In a final embodiment Fig. 5, (not shown) the suspension filament is attached at its rear end to a rod, pivoted in a diaphragm, whose further end is moved orthogonally by servo-motors through rack and pinion links, the detectors being as in Fig. 2.
