Title: Piston for IC engine - has recess in head which causes air-fuel mixture to circulate
Inventor: AUGUST PAUL DR
IPC: F02B23/08
Filed: 1989-04-20
Abstract: The piston (2) of an IC engine has a recess (21) formed in its crown. This recess has a generally square plan form but with one of the sides (17) being curved.

Title: Control system for storm drain - has programmed control for gate valve and with level monitoring in cistern
Inventor: WEBER KARL
IPC: E03F5/10
Filed: 1990-03-15
Abstract: The rainwater collects in a cistern and drain out via a storm drain (2). Flow monitors (9) measure the flow-rate when the drain is full and a gate valve (3) regulates the flow rate. The water level in the cistern is monitored by a level gauge (7), also linked to a processor control (6). The system regulates the outflow, and can be linked to a number of cisterns to regulate the total flow into a drainage system. As the water level rises in the cistern the flowrate is montiored and kept to the required maximum. This is determined by the overall system conditions. When the level starts to fall the amximum flow is maintained by the gate valve control until the cistern is empty. ADVANTAGE - Flooding control, fast reaction, can be linked to system control.
