Title: Wave force driven power generator - has float with fixed horizontal position, but unlimited freedom of vertical movement, utilised for drive purposes
Inventor: PUTZ ELMAR
IPC: F03B13/18
Filed: 1980-07-23
Abstract: The float (1) of the power system cannot change its horizontal position in relation to the mainland, sea or river bed, ship, or float frame. Its movement freedom in the vertical direction is not limited. The vertical motions of the float are exploited by appropriate mechanisms of a design such that they are not affected by the wave movement. The exploitation platform is preferably rotatable or vertically movable in such a manner that even with stationary mechanisms matching to the wave movement or to the tide can be attained. Typically, the extracted power can be used for water craft drive. During storms the vertical stroke of the float may be limited. Only one of both vertical motions of the float (up or down) may be used for energy generation. Several wave driven mechanisms may be combined to form a power plant, and drive a generator (10).

Patent DE-3042796-A1 (DE)
Title: Piece-goods spin dryer - has winding sleeve in drum to allow fabric to unwind for spin drying
Inventor: HOFFMANN ERNST DIPL ING
IPC: F26B5/08
Filed: 1980-11-13
Abstract: To extract fluid from textile piece goods by centrifugal force, the fabric is wound round a sleeve or a spindle within a spin-drying drum, so that their axes are parallel. The masses are sufficiently equal to allow the fabric to unwind from the sleeve as the drum rotates, to be held by centrifugal force against the inner wall of the drum. The drum speed is increased to extract fluid from the fabric centrifugally, after which the material is rewound on the sleeve. The rotary speeds, from start to finish of the drying process, are calculated so that the centrifugal force applied to the fabric is as great as the gravity, and the shift into and out of the spin drying phase is effected without interruption of the rotation. The process allows long lengths of fabric to be dried without cutting, after washing or dyeing or other wet treatment, so that the fluid is mostly extracted from the material.
