Title: Rotary fluid tight coupling
IPC: F16L27/08
Filed: 1979-07-16
Abstract: A rotary fluid tight coupling comprises a hose-connecting adaptor (4) and a hose-connecting sleeve (7) rotatably supported on the hose-connecting adaptor by at least one bearing (5) and at least one circular gasket (6), the hose-connecting sleeve (7) being subdivided into a bearing sleeve (7a) and a cap (7b) screwed on to it, the cap having a connection (8) for a hose, and the gasket (6) being located between the cap (7b) and the adjacent end (9) of the adaptor (4) and having pressure- equalization surfaces (10, 11) on both sides.

The profile portions may be extruded from the die in facing relationship. <IMAGE>
Patent GB-2057646-A (GB)
Title: Gas gun for ballistic testing
IPC: F41B11/00
Filed: 1980-08-01
Abstract: A gas gun has a charge chamber, an inlet valve to admit a charge of compressed gas to the charge chamber and either a plane or rifled barrel which communicates at its breech end with the charge chamber via a rotary outlet valve. Preferably the inlet valve is linked to the outlet valve so that closing of the inlet valve immediately precedes the opening of for the outlet valve. The outlet rotary valve is of the type wherein a valve member rotates within a complimentary seat and has a radial bore which can connect two or more ports in the wall of the seat and is strongly biassed to the open position. The inlet and outlet valves may be combined in a three-way valve. In use a projectile is placed at the breech end of the barrel and the inlet valve is opened and the outlet valve closed. After compressed gas, preferably helium, has been introduced to the charge chamber to the desired pressure, the gun is fired by closing the inlet valve and immediately thereafter opening the outlet valve. The projectile expelled thereby has a velocity that is determined in part by the gas pressure in the charge chamber and may readily be varied by adjusting the gas pressure. Chamber pressures in the range 500 to 1500 psi lead to projectile velocities of the order 250-460 metre/second. The gas gun is especially useful in ballistic testing of, for example, personal armour. <IMAGE>

Title: Silos
IPC: B65D90/02
Filed: 1980-11-26
Abstract: A silo for grain or the like has a circular wall 3, composed of curved corrugated sheets whose corrugations extend horizontally (in the circumferential direction of the wall), and a discharge outlet 8 located at or adjacent the base of the wall. The corrugations provided have a larger than usual ratio (greater than 5:1, and preferably 10:1 or 12:1) of pitch (crest-to-crest) to depth (crest-to- trough) and the friction forces on the wall are thereby much reduced.

Title: Meter provers and methods of proving flow meters
IPC: G01F25/00
Filed: 1980-11-28
Abstract: A meter prover has a linearly displaceable piston 15 which is associated with a position encoder 24 adapted to provide signals denoting increments of movement of the piston along a cylinder during a proving run. The beginning and end of the proving run are defined by pulses from the meter 2 and in particular pulses which are spaced apart by an integral number of cycles of metering by the meter. Thus the actual displacement of the piston is measured during an interval defined by the meter. The piston is retracted by a piston and cylinder arrangement 30,31. <IMAGE>

Title: A rechargeable portable lighting device
IPC: F21L4/08
Filed: 1981-04-30
Abstract: A portable lighting device has a body (1) to which a handle (18) is pivotally attached so as to be movable from one position, in which it covers and protects a recharging plug (15, 16) protruding from the body and allows bulb (6) to be illuminated, to other positions in which the plug is exposed for recharging and the normal power supply to the bulb (6) is disconnected. A switch mechanism for controlling the power supply to the bulb is mounted on the upper journal bearing of the handle on the body (1) and comprises a knob (30) connected to a sliding plate carrying contact portions (37) which interconnect contact surfaces on a base plate (38). Pivotal movement of the handle (18) to expose the recharging plug moves the sliding plate to a position in which it cannot engage the contact surfaces.

Title: Suspended ceiling
Inventor: WILCOCK ALFRED
IPC: E04B9/34
Filed: 1982-06-21
Abstract: In a ceiling formed of intersecting ceiling members 1, 2, 3, 4 (e.g. of generally U-shaped cross-section with the bases of the U's at the bottom) an opening e.g. for lighting, is stabilised by a rigid frame formed by four frame members 6. The frame will surround the opening, and is supported by brackets 12 which interlock with the respective frame members 5. Each bracket 12 has a locating part 18 which is inserted into the top of the U of the ceiling member 1, 2, 3 or 4. It is not necessary to fix the part 12 to the ceiling member 1, 2, 3 or 4 and some horizontal play can be allowed. However, the weight of the frame is taken by the brackets 18 and the frame stabilises the opening. In order to facilitate assembly, the brackets 18 can be slid along the frame members 6 into their correct position. A detachable panel 22 is held in the opening by means of horizontally- sliding, spring-loaded bolts 23 actuated by projecting handles 25. <IMAGE>

Title: Impulse protection device
Inventor: MELLOR DAVID JOHN
IPC: H01T4/08
Filed: 1982-06-24
Abstract: The device has a Ne or Ar filled chamber 7 through which independent conductors 1-6 pass, and includes an insulating plate 10, which has a shaped conductive coating 14, e.g. of molybdenum manganese, spaced from the conductors and so arranged that a plurality of spark-gaps 16 are provided between the conductors 1-6 and the respective adjacent portions 15 of the coating 14. When one spark-gap breaks down, all the remaining spark- gaps also breakdown. Thus if a very large impulse appears on the conductors e.g. due to nearby lightning or nuclear explosion, the first spark- gap to breakdown, e.g. connected to non-sensitive equipment, triggers the remaining spark-gaps thereby protecting any sensitive equipment connected to the other conductors. Areas of plate 10 not provided with conductive coating 14 may have an insulating film 18 of barium titanate to enhance breakdown of the gaps. <IMAGE>
