Patent GB-2177153-A (GB)
Title: Striking plates
Inventor: PLUMB NIGEL PETER
IPC: E05B15/02
Filed: 1985-07-05
Abstract: A striking plate (4) is adjustably mounted to a frame portion (2) by passing screws (18) through countersunk holes (20, 22) in the striking plate (4) to engage with eccentric tapped holes (14) in cylindrical adjusting members (8) received within an inwardly-open channel (6) of the frame portion (2). The cylindrical face of each adjusting member is provided with grooves (16) which can be engaged by a screwdriver tip to slide the member axially of the channel or rotate it in order to adjust the position of the eccentric hole both longitudinally and transversely of the channel and therefore adjust the position of the striking plate. Tightening of the screws results in immovable engagement of the adjusting member with inner faces of flanges (10, 12) of the channel. <IMAGE>
Patent GB-2163245-A (GB)
Title: Improvements in or relating to fluid flow controls for refrigerators and heat pumps
Inventor: KNIGHT JOHN RUSSELL
IPC: F25B41/06
Filed: 1985-08-15
Abstract: A self-regulating capillary flow control for the fluid circuit of a refrigerator or heat pump, incorporating a reservoir 7 on the high pressure side of the circuit between the condenser 2 and the capillary 8. Fluid can reach the capillary 8 from the reservoir 7 by two routes 15, 18, a cooled route 15 leaving the reservoir 7 by an overflow outlet 10 at relatively high level and a warmer route 11 leaving it at lower level. Slow flow through the capillary 8, indicating warm fluid, causes the reservoir 7 level to rise. When it overflows, cooler fluid reaches the capillary 8 so that the flow rate within it rises. This draws further fluid from the reservoir 7 by the warmer route 11, so that the reservoir 7 level falls, the overflow stops, and flow within the capillary 8 falls. The liquid level then stabilises. Several alternative designs of reservoir are described, and also both unvalved designs of the warmer route and a design fitted with a pressure-dependent valve. <IMAGE>

Title: Conveyor safety apparatus
Inventor: GRINDROD JAMES JEFFREY
IPC: B65G43/00
Filed: 1985-12-14
Abstract: Conveyor safety apparatus (10) comprises a frame (12) in the form of two upright legs (13) mounted on the sides (16) of a conveyor (11) and having a mounting beam (14) extending between the upper ends of the legs (13). A movable member (22) in the form of a shaft is mounted in a housing (18) on the mounting beam (14) and has a plurality of angle brackets (23) secured thereto at mutually spaced axial locations. Depending from each bracket (23) is a flexible chain/cord member (24) which when pulled causes pivoting of the shaft (22) about its axis so that a switch actuator plate (28) attached to the shaft (22) contacts and actuates an adjacent, manually resettable switch (30) to cut off the electrical supply to the conveyor (11). A person trapped on the moving conveyor (11) should easily be able to reach and pull one of the flexible members (24) to stop the conveyor (11), but goods will simply deflect the flexible members (24). <IMAGE>

Title: Temperature sensitive waveguide attenuator
Inventor: WATSON BARRY KENNETH
IPC: H01P1/22
Filed: 1986-03-05
Abstract: A temperature sensitive power attenuator for millimetre wave systems comprises a pair of millimetre waveguide, 4 port, 3dB couplers (1) and (2) series connected through a further pair of shunt 3dB couplers (3) and (4) having short-circuit terminations (5) and (6) respectively to their output ports. The short-circuit terminations (6) of one of the shunt 3dB couplers (4), but preferably both, are movable towards or away from the coupler (4) in response to temperature change so that the difference between the path lengths (7 to 8) and (9 to 10) between the first pair of couplers (1) and (2) through the shunt couplers (3) and (4) respectively is varied according to the temperature. Power input at port (25) of the coupler (1) is divided and effectively attenuated at the output port (26) of the coupler (2) depending on the difference between the path lengths through the shunt couplers (3) and (4) and hence on the temperature. The movable short-circuit terminations may be slidable plungers or bellows waveguide extensions, and may be connected for simultaneous movement. <IMAGE>

Title: Depositing vaporized material uniformly
Inventor: KAMIO MASASHI
IPC: C23C14/32
Filed: 1986-04-01
Abstract: Substrates (25) as illustrated in Figs. 3 and 5 are rotated about respective axes which are positioned a fixed distance away from a center axis, which corresponds to an emission point (12) for the vaporized material, which is ionized so that it stays in contact with the substrates after collision. Because the substrates (25) are rotated, the vaporized material is deposited with a uniform thickness on the substrates. <IMAGE>

Title: Photosensor array
Inventor: HATANAKA KATSUNORI
IPC: H04N5/374
Filed: 1986-04-11
Abstract: Each photosensor Sr1... in an array is connected in parallel with a FET switch STr1 ..., which is normally closed to by-pass the photosensor. The photoresistors in each column are connected in series. To read any photoresistor its associated switch is opened via a row conductor Tr, Tg, Tb and an output sensed at the base A1, A2,..., An of the column. Series connection allows fewer conductors to be used compared to the prior art (fig. 3). 
<??>In an alternative embodiment, each photoresistor and FET switch is replaced by a single photosensitive FET (fig. 7).

Title: Mounting telescopic sights on air guns
Inventor: WHITE KENNETH WILLIAM
IPC: F41G1/387
Filed: 1986-04-14
Abstract: An air gun, instead of having dovetail recesses formed directly in the body tube 2 of the gun for mounting a telescopic sight, is fitted with a carrier 6 including a dovetail 8 to be engaged by clamps of mounts for a telescopic sight. The carrier extends along the axis of the body tube 2 and is mounted thereon by passing downwardly-projecting integral headed parts 10 through enlarged portions of keyhole shaped openings 12 in the carrier and then moving the carrier axially with respect to the body tube 2 to take the headed parts 10 into narrower portions of the openings. Resilient strips 11 are interposed and tightly compressed between the carrier 6 and body tube 2. Instead of being integral, the headed parts 10 may be separate components secured to the carrier by screws, or the heads of screws engaging threaded holes in the carrier may themselves form the headed parts for engagement with appropriately dimensioned keyhole openings.   <IMAGE>

Patent GB-2220158-A (GB)
Title: Machining screw threads
Inventor: SHIRAKURA TAKEO
IPC: B24B19/02
Filed: 1989-06-13
Abstract: In known methods of machining a screw thread in a member, for example by grinding, it is usual to tilt the spindle carrying the grinding wheel in accordance with the lead angle of the screw thread. This technique makes it difficult to grind a female thread of small diameter and having a deep groove as the grinding wheel spindle and member being machined interfere with one another. …<??>A method of machining a screw thread which overcomes the above disadvantages is achieved by shaping the tool, particularly a grinding wheel, in accordance with screw thread parameters then using the shaped tool with its axis parallel to the screw thread to machine the thread itself in the member. …<IMAGE>…
