Filed: 1972-01-11
Abstract: 1371381 Lasers EMI Ltd 11 Jan 1972 [15 Jan 1971] 2019/71 Heading H1C In a ring laser, mode locking between the two counterrotating beams due to back scattering of the beams from imperfections in a planar corner mirror is cancelled by vibrating the mirror in the plane of its reflecting surface. The ring laser is thus able to measure low rotation rates when used as a compass. In the embodiment of the figure a mirror 1 at a corner of the ring is vibrated in its plane, as shown by arrow 6. The vibration is chosen to reduce a spectral component of the back-scattered wave corresponding to the laser circulating frequency. The vibration may also be chosen so that the first order sideband components of the scattered wave lie outside the operating band of frequencies of the laser system. The vibrations may be produced by a piezoelectric device.

Abstract: 819,528. Hydraulic couplings. VAN DER LELY, C. Jan. 24, 1956 [Jan. 18, 1955], No. 2319/56. Class 69 (2). An hydraulic coupling comprises a centrifugal pump producing a flow of liquid past rotating members which are rotatably mounted in a disc fast with the output shaft, the output shaft being driven due to the torque produced by the Magnus effect. In the embodiment of Fig. 1 pump blades 12 fast with an input shaft 1 drive liquid through channels 38 in a stationary housing and past cylinders 30 which are rotatably mounted in a disc 22 fast with an output shaft 2 and which carry gears 28 meshing with internal teeth on a member 15 fast with the input shaft 1. A second set of cylinders 51 is mounted in the stationary housing and geared to the input shaft and acts as a reaction member ensuring that the liquid enters the pump blades 12 at the correct angle. Blades 31 are loosely pivoted about the axes of the cylinders 30, and fixed or loosely pivoted blades are associated with the cylinders 51 to guide the liquid as it leaves the cylinders. In the embodiment of Fig. 4 pump blades 63 driven by an input shaft 60 supply liquid to the periphery of secondary centrifugal pumps 73 which are mounted in a member 69 fast with an output shaft 70 and are driven by gears 72 meshing with a gear 64 on the input shaft. The secondary pumps discharge the liquid supplied by the main pump, together with liquid drawn into the secondary pump inlets 78, through channels 75, 65 in a stationary housing to the inlet of the main pump. In the embodiment of Fig. 6 a pump 91 supplies liquid to turbine members 100 which are rotatably mounted in a disc 97 on the output shaft. The liquid supplied by the pump rotates the turbine wheels and the torque due to the Magnus effect again rotates the output shaft. In a modification of this embodiment each member 100 is rotated by means of a fluid stream which drives a member fast with the axle of the member 100, and member 100 need not have blades.

Title: Apparatus for producing a supply of gaseous working fluid for the operation of a prime mover
Inventor: GRIEVE ALEXANDER
IPC: F02C7/272
Filed: 1955-01-26
Abstract: 787,571. Generating combustion products under pressure. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 10, 1956 [Jan. 26, 1955], No. 2380/55. Class 51 (1). [Also in Group XXVI] In an apparatus for producing a supply of working fluid for the operation of a prime mover by decomposition of a mono-fuel within a reaction chamber 1, combustion of the mono-fuel is initiated by introducing the products of combustion of a deflagrant such as cordite into the chamber. The pressure drop in the conduit 11 leading from the breech 10 in which the cordite is contained to the reaction chamber is compensated for by providing means for producing a flow of mono-fuel into the conduit where it is decomposed by heated gaseous products of combustion of the cordite. Mono-fuel is supplied to the reaction chamber 1 from a container 2 through a pipe 8, non-return valve 9, a pressure intensifier 3 and pipe 4. The pipe 4 is divided so that some mono-fuel passes directly to the chamber 1 while some passes to injector 13 and into the duct 11 where it is decomposed by the hot gases from the cordite charge fired in the breech 10. The increased pressure resulting from the decomposition of the mono-fuel in the duct 11 offsets the drop in pressure that would otherwise occur. The invention is applicable where gases from the chamber 1 drive a turbine which starts a gas turbine or other internalcombustion engine. The breech 10 may in such cases be disposed at some distance from the reaction chamber 1 and the pressure loss in the duct 11 may be considerable. The pressure intensifier 3 contains a differential piston 5 and the top of the piston communicates with the pressure in the reaction chamber 1. The device 3 may contain sufficient mono-fuel to permit a single operation of the starter turbine. Specifications 784,121 and 787,572 are referred to.

[Class 78 (v)] [Also in Groups XXIV and XXXVII] A chain guard, more particularly for electric pulley hoist blocks, and which may also act as an emergency switch for the power motor, comprises a plurality of blocks 16 strung in line on one or more cables 17. The blocks have their contacting faces shaped so that when pressed together in normal use by end springs 22 they form a continuous strip which can be draped over the chain 11 where it passes round a sprocket wheel &c. 10. The strip ends curve outward for attachment to the pulley block frame and the springs 22 react against adjustable stops 23 slidable on the cables 17. The blocks 16 are curved on their outside and inside faces 20, 19, and the inside face is grooved medially to receive the chain links. Any fouling of the chain 11 over the sprockets will result in the strip of blocks 16 becoming displaced and disarranged. When the strip is to function as a switch, each block is fitted with a longitudinally extending conductor 25, insulated if necessary. A spring - pressed contact 26 at the end of each conductor 25 normally touches the end of the neighbouring conductor to form a continuous path along which the motor current may flow, connections 28 being housed at the ends of the strip in a block having a removable wall 30. The connections may be such that when the strip is disarranged the motor is stopped, or otherwise that it is reversed. The blocks 16 may be of soft metal or of any suitable material, such as an insulating substance, A chain stripper 12 may be fitted.
