Title: Sea-water desalination - by vapour compression downdraught evapn. combined with multistage evapn.
Inventor: LAMMERS JOERG DR ING
IPC: C02F1/04
Filed: 1979-12-21
Abstract: Distn. process for the desalination of seawater is based partly on an evapn. combined with vapour compression and partly on multi-stage evapn. The brine flow and the distillate flow in each part process are circulated in separate circuits. The supply of make-up water by which the substances extracted from each circuit are compensated is kept separate for each part process, but both are extracted from the heated coolant flow of the cooling section of the multi-stage evapn. process. The capacities of the two part processes are thus not limited by an internal coupling. The profitability of such a plant is raised, specially when no waste heat from power stations is available.

Title: Mast-foot arrangement for a windsurfing board
Inventor: PERTRAMER SIEGFRIED
IPC: B63B35/79
Filed: 1981-02-03
Abstract: The invention relates to a mast foot (1) for windsurfing boards (2). The universal joint (4), which connects the mast (6) to the windsurfing board (2) via the mast foot (1), is fastened to a centre pin (7) of a bearing device (3). The bearing device (3) is firmly connected or can be firmly connected to the windsurfing board (2). The centre pin (7) can be moved relatively upwards together with the universal joint (4) essentially perpendicularly to the deck surface of the windsurfing board (2) relative to the rest of the bearing device (3) against the force of a spring (21). The spring (21) can be adjusted in its force exerted against an upward movement of the centre pin (7). Due to this arrangement, in the event of a part of the body getting caught between the folded mast (6) and the deck surface of the windsurfing board (2), the entire mast foot (1) is no longer released from the windsurfing board, but the fixed connection is retained and the distance between deck surface and mast (6) is increased merely by upwards movement of the centre pin (7) against the spring (21). In this way, injuries due to a part of the body catching are impossible. <IMAGE>
