Title: Improvements in Automatic Pilots
IPC: G01C17/04
Filed: 1980-11-21
Abstract: In a signal source for the lateral channel of an automatic pilot, a heading error signal is generated directly from a pneumatic sensing hole 20 which can be covered or uncovered by shield 17 attached to a magnetic needle 16 of a compass carried by a gyroscopically stabilised platform 10, the error signal being at zero when the hole is partially covered.

Patent GB-2093162-A (GB)
Title: Liquid flow control valves
IPC: F16K24/06
Filed: 1981-02-13
Abstract: A water inlet valve for a lavatory cistern includes a valve chamber 2 communicating with which is an outlet pipe 11. The outlet pipe includes a horizontal portion to which is connected a vertical portion 20 which extends down to below the minimum water level in the cistern. The vertical portion 20 is laterally offset from the horizontal portion when viewed in plan and coaxial with the vertical portion is a hollow circular section diverter body 26 which connects the interior of the outlet pipe to the atmosphere via an aperture 24. In use the water is caused to swirl downwardly in the pipe 20 due to the offset disposition of the diverter body 26 and this results in a core of air always being present in the pipe 20. If a back-pressure should develop in the supply main, air is sucked into it via the aperture 24 rather than contaminated water being back- syphoned from the cistern. <IMAGE>

Title: Improved Rivetting Structure for a Torque Converter
IPC: F16H41/28
Filed: 1981-07-02
Abstract: Rivets (19) serve to connect a turbine runner shell (7a) to the turbine hub (12) of a torque converter (4) and simultaneously serve as connectors, spacers and part of a lost-motion connection in a lock-up clutch damper mechanism. To protect the press- formed turbine runner shell (7a) from deformation during rivet head (19d) formation, a hard annular rivet head motion shield (27) is interposed between the head (19d) of each of the rivets (19) and the turbine runner shell (7a). To prevent bending of the rivet shanks which form part of the lost motion connection, a flange (19e) is provided on each rivet which flange abuts a side plate (18) of the damper mechanism to disperse the force applied thereto upon the rivet shanks abutting the edges of apertures (7b) in the lock-up clutch hub which apertures define part of the lost motion connection. <IMAGE>
