Title: Small two stroke IC engine - has additional inlet in transfer passage between crankcase and cylinder
Inventor: BLAIR GORDON PURVES
IPC: F02B25/14
Filed: 1979-05-11
Abstract: A piston (P) reciprocates in a cylinder (M) with a closed crankcase (L) beneath it. There is a fresh air inlet (G) into the crankcase. The air entering here is compressed on the downstroke and then transferred to the cylinder through passages leading to ports (B, H) in the cylinder. An additional passage (K) from the crankcase to the cylinder has a further inlet (F) between the crankcase and the cylinder. Fuel and air are injected through this opening. The ports (B, H) from the first transfer passage and the port (A) from the second are positioned to give both radial and tangential scavenging flow. This increases efficiency.

Title: Multiple effect evaporation desalination plant - has heat pump and uses reduced pressure to utilise heat from sea water to evaporate off fresh water
Inventor: CREDE HELFRIED DIPL PHYS
IPC: B01D3/00
Filed: 1979-09-29
Abstract: A quantity of sea water is held at a reduced pressure at a temp. below that of the bulk of the sea water. It is in heat exchange contact with the sea water and water is evapd. from it. The vapour is condensed in a refrigerant condenser driven from a refrigeration plant with an I.C. motor.
