IPC: F04C15/00
Filed: 1981-09-28
Abstract: In a pump having a pressure-loaded cheek plate 14 abutting the pumping means e.g. externally-meshing gears or rotor with sliding vanes, extrusion of a seal 16 in a pressure-loading chamber 15 is prevented by an adjoining sheet of substantially stretch-resistant material such as aluminium, a fabric, or a plastics material. <IMAGE>
Patent GB-2088954-A (GB)
Title: Pressure Relief Device
IPC: F16K17/16
Filed: 1981-10-06
Abstract: A pressure relief device includes a bellows assembly (5) for moving a diaphragm (17), which functions as a bursting disc, against a knife blade (24). The device is coupled by a flange (25) to a pressure source whereby a housing (2) around the bellows and a tube 1 closed by the diaphragm (17) are pressurised. An increase in pressure causes the bellows to move the tube 1 against the action of a reference spring (13) chosen to cover the range of pressures required. At a predetermined pressure the diaphragm (17) is penetrated by the specially shaped knife blade (24) to relieve pressure. <IMAGE>

Title: Projectile launching device
Inventor: ALLEN ROGER FREDERICK
IPC: F41B11/00
Filed: 1982-08-19
Abstract: A device for launching a projectile for line-throwing or one containing equipment (eg a liferaft) comprises a barrel (12, 14, 19) recessed to form between it and the projectile (29) a chamber (23) for containing compressed air. A forward resilient seal (32) is mounted in the projectile or the barrel, while the rear of the projectile (29) is provided with a resilient skirt (33) engaging a boss (22) extending forwardly from the rear of the barrel. Compressed air supplied to the chamber (23) presses the skirt (33) against the boss (22) to produce a frictional resistance sufficient to hold the projectile (29) in the firing position. The projectile (29) is advanced from the firing position under the action of a secondary supply of compressed air applied to the rear of the projectile and when the skirt (33) moves clear of the boss (22) the compressed air in the chamber (23) acts on the rear of the projectile to propel it forwardly along the barrel. <IMAGE>

Patent GB-2117060-A (GB)
Title: Hydraulically operated apparatus
Inventor: KENNEDY JOHN STRAUGHAN
IPC: F15B18/00
Filed: 1982-09-30
Abstract: Hydraulic systems A, B, e.g. in a ship's steering apparatus, are simultaneously operable by means equalizing the pressure between the pumps 10, 11 in the respective systems A, B. Preferably, this is accomplished by interposing piston and cylinder assembly 128 between respective pump actuating rods 141, 143. During steering, pressures of respective systems A B, are applied to assembly 128 at inlets 122, 121. If there is an imbalance in said pressures, piston 123 and trunnion 124 move, thereby altering the effective length of lever 125 until the stroke of pump 10 is equal to that of pump 11. Other methods of equalising pressure between pumps 10, 11 include providing pressure sensitive control valves or spill valves between each side of each system A, B. <IMAGE>

Title: A method for detecting a thread failure in tufting machines
Inventor: VON BRUNN WOLFGANG
IPC: D05C15/18
Filed: 1982-12-20
Abstract: The invention relates to a method for detecting a thread failure in tufting machines using thread-sensing elements 17,18 emitting electric signals corresponding to the thread tension. The periodic variation of the thread tension is used as a criterion for determining whether or not the thread is running correctly and the non- appearance of this periodic signal is regarded as indication of a failure, and further that the signals are compared at 33 with reference signals and an alarm 35 is released only when several defect signals are encountered in uninterrupted series. The reference signals are generated by pick-up devices during each cycle of operation. The signals corresponding to thread tension periodically change between maximum and minimum values. These may be counted to detect thread leakage. <IMAGE>

Patent GB-2137828-A (GB)
Title: Strobe Lighting Arrangement
Inventor: MARDON PAUL FRANCIS
IPC: H05B41/34
Filed: 1983-03-29
Abstract: A strobe lamp 30 is supplied with power from a power supply circuit in which the power supply circuit operates so as to maintain approximately constant power consumption independent of flash rate within a predetermined working flash rate range. In this way the rating of the lamp is not exceeded at higher flash rates and greater brilliance is available at lower flash rates. The lighting effect is enhanced at low flash rates where previously four joules per flash has been common and now a theoretical twenty-five joules per flash can be achieved. The lamp discharge voltage varies from 200 volts at 25 flashes per second to 680 volts at one flash per second and the limitation of energy per flash is achieved by selecting the values of two capacitors, one 44 connected in series with the discharge lamp 30 and the other 38,40 in parallel therewith in a voltage doubler circuit. Typical values are 12  mu F and 70  mu F for the series and parallel capacitor respectively. Power consumption is maintained constant within +/-15% over a range from 2.5 to 20 flashes per second. With a switch 12 closed, the flash rate is varied by an adjustable resistor 24 in a lamp firing circuit 14 with switch 12 open the flash rate is controlled by an input signal supplied to a jack 32 and derived from a musical rhythm. <IMAGE>

Abstract: The device comprises a layer of long-pitch cholesteric liquid crystal material of positive dielectric anisotropy. An amount of pleochroic dye is contained between two cell walls bearing electrodes and being surface treated to align liquid crystal molecules in a tilted homogeneous structure. The surface alignment and natural pitch of the cholesteric material are matched to provide a molecular twist of between pi and 2pi radians across the layer with a uniform tilt direction. The ratio of layer thickness d divided by pitch p lies between 0.5 and 1.0, d being less than 20 microns. The device may be switched directly between a light transmissive ON state and a non-transmissive OFF state. The device has a sharp transmission/voltage characteristic and negligible hysterisis.

Title: Apparatus for storing and dispensing powdered material
Inventor: POLHILL HAROLD GEORGE
IPC: B65D88/72
Filed: 1984-01-03
Abstract: A container 1 holding bulk cement 7 has a screw conveyor 8 which extends downwards into the container 1 within a surrounding tube 12, which is in turn surrounded by an air-permeable fabric sleeve 27. Compressed air is supplied through a pipe 33 to the space within the sleeve 27 and the air flowing through the sleeve fluidises the cement surrounding the sleeve. The whole of the screw conveyor assembly is pivotally mounted on trunnions 15 and can be swung by a driving mechanism 20-25 from one side of the container 1 to the other. By fluidising the cement surrounding the conveyor and causing the conveyor to sweep through the container in this way, the whole contents of the container can be drawn in through the open bottom end 13 of the tube 12 and be discharged through a flexible pipe 9. By providing the movable conveyor, the container 1 can be made of a much larger capacity than a hopper with sloping sides which occupies the same area in plan. <IMAGE>

Title: Light Beam Stabilizer
Inventor: FULKERSON EMMET MITCHELL
IPC: G02B27/64
Filed: 1984-02-09
Abstract: Apparatus for reducing the effects of pointing instabilities in a light source, e.g. a laser comprises two coaxial lenses 9, 12 sharing a confocal point 7 and comprises a rotatable parallel dielectric (e.g., glass) plate 34 positioned between the lenses and intersecting the axis. A collimated, incoming laser beam 3 is projected to a first of the lenses, focused through the plate to the confocal point, and received and recollimated by a second of the lenses. A beamsplitter 23 diverts part of the recollimated beam toward a photosensor 26. Angular deviation of the incoming laser beam from the axis results in an angular deviation of the recollimated beam as well as in failure by the first lens to focus the laser beam at the confocal point and, further, in a translation of the diverted part of the recollimated beam across the photosensor. A resulting error signal is fed to a motor 36 which rotates the plate to restore focus at the confocal point and to thus reduce angular deviation of the recollimated beam. <IMAGE>
