Title: Conversion of rotary motion into reciprocating linear motion - using 2 parallel chain drives linked by lateral roller bolt with interposed pusher rod
Inventor: SAGARA HIROSHI
IPC: F16H35/00
Filed: 1977-04-28
Abstract: Two endless chain drives (3) which run over two pairs of coaxial sprocket wheels (31, 32, 34, 35) are linked together by a lateral roller bolt (5, 51).

Title: Reversible drive shaft on model racing car - has changeover cage to retain forward drive after steering alteration
Inventor: NEUHIERL HERMANN DIPL CHEM DR
IPC: A63H18/16
Filed: 1977-05-20
Abstract: Model car for racing on a special track has a direct current operated drive motor (2, 3).

Title: Rack element for holding printed circuit board - has secure location for edge connector incoming cable using socket which fits into plate
Inventor: MUELLER JOACHIM
IPC: H05K7/14
Filed: 1977-08-09
Abstract: The back element of the printed circuit board anchors the cable leading to the edge connector (14). Each cable is secured to a support plate (15a, 15b) by ties or clips.

Title: Water supply control from pumps to overhead tank - involves counterweight moving flap to close off pump, using water via by=pass
Inventor: SOEHNE PAUL
IPC: G05D9/02
Filed: 1978-08-09
Abstract: The device is for regulating the flow of water in the raised tank or reservoir of a water supply system, from pumps in a remote pumping station, in the event of control cable failure. A flap (3) is mounted on a rocker (7) in front of the intake opening (2) of the pump duct (6) leading to the tank (5). When at rest, this is held in a position releasing the opening from the duct.
