Title: Lightweight helicopter with twin contra-rotating rotors - has power supplied by small engine supplemented by pedal drive
IPC: B64C27/10
Filed: 1975-04-16
Abstract: The helicopter frame is of aluminium tube with a vertical tube housing the bearings of the rotor drive. The rotors rotate in opposide directions. Each rotor has two concentric rims supported by spokes. Aerofoil blades are fitted between the rims with an angle of incidence of 3 deg. to 8 deg. The rotors are driven by belts from the engine which powers an endless belt drive. The engine power which is about one third of a horsepower can be supplemented by the pilot operating pedals attached to the driving pulleys. The helicopter is controlled in flight partly by a lever which varies the speed of one or other of the rotors and partly by moving a weight, at the front of the helicopter.

Title: Ball valve with spring loaded seal - has seal friction reduced by removing spring load as valve opens
Inventor: DOMYAN FRANCK FRANCIS
IPC: F16K5/06
Filed: 1976-11-09
Abstract: The ball valve has a spherical section with stub shafts (26) running in needle roller bearings. A sealing ring mounted in a sleeve (36) is normally pressed against the spherical surface (21) by a helical coil spring. The spring load is transmitted through a pair of rings (34, 35) held apart by diaphragm springs. A pair of cams mounted on the valve stub shafts actuate short push rods (42') which pass through slots in the ring (35). As the valve ball is rotated from the closed position the spring (40) is compressed and the load on the seal is removed. This reduces the operating friction and the wear on the seals.
