Title: Spinning disc for tossing persons into water - uses drive unit anchored in water to turn upper disc relative to lower
Inventor: WUNSCHIK GEB RADAN ZLATA
IPC: A63G3/04
Filed: 1975-04-30
Abstract: The spinning disc is used in the water and when it begins to rotate, tosses persons seated on it into the water by centrifugal force. It comprises an upper disc (1) which is moutned rotatably on a lower disc (5) both made of plastics, wood or metal, and reinforced with ribs or a tube structure (6). The upper disc may overlap the lower disc, and is driven by electric, hydraulic or pneumatic means (12) with an energy supply line. Buoyancy of the spinning disc may be controlled by flotation tanks (8) or by lift members e.g. made of hollow foam, which become superfluous if flexible anchoring means are replaced by rigid anchoring means (10). The disc may be surrounded by a sinkable rim (14) for climbing onto the disc if the disc is rigidly anchored or if the rim is movable mechanically connected to the lower disc.

Patent DE-2528733-A1 (DE)
Title: Organically substd. hydrazine mfr. - involves finely dividing liq. phase when adding chloroamine
Inventor: CLASEN HERMANN DIPL CHEM
Filed: 1975-06-27

Title: Clutch coupling with over run facility - has centrifugally responsive coupling dogs acting against spring force
Inventor: GOETTMANN WERNER
IPC: F16D41/07
Filed: 1975-07-19
Abstract: A clutch coupling utilises spring biased drive dogs that respond to centrifugal force and provide an over-rim facility. The drive shaft is rigidity connected to an internal bush (2) via a keyway (8). An outer sleeve (1) is bolted (7) to a machine member. Between the inner bush and outer sleeve is a two part (3) cage with projecting studs (12) that provide location for the drive dogs (4). Close coil helical springs locate tightly in holes of the dogs to provide a bias force when the input shaft rotates. Projections (11, 28) allow the dogs to pivot far enough for full transmission within the selected speed range. As the speed approaches the valve, centrifugal force counterbalances spring force until the dogs swing against the stops to disengage the drive.

Patent DE-2554110-A1 (DE)
Inventor: SITTMANN GEB VOESTER BRIGITTE
IPC: A63C7/10
Filed: 1975-12-02
Abstract: The ski brake has a rotary bar (1) which is mounted so as to be rotatable about the transverse axis of the ski and whose ends located ahead of the axis of rotation form the brake blades (11) and whose part which connects the bar ends and is located behind the axis of rotation is constructed as a holding bar (12). A web (15) projects substantially in the direction of the axis of rotation from a transverse part (14) of the holding bar (12) facing away from the axis of rotation. In the braking position, said web (15) encloses a greater angle with the upper surface of the ski than the plane of the holding bar (12). In this manner, when the rotary bar (1) is pressed down into the rest position by pressing the web (15) into the plane of the holding bar (12) a resilient opening moment is produced. <IMAGE>

Abstract: A pair of overhung and replaceable roll collars one on parallel carrier shafts, adjusted radially to each other by an eccentric. Both carrier shafts can be coupled to a further shaft for the drive train and each roll stand is connected to the pinion housing such that the carrier shafts and the other shafts can be coupled at their ends by means of a cross friction clutch. The coupling of the carrier shaft to the opinion shafts does not allow the transmission of bending forces from the rolling process to the drive shafts.
