Patent DE-3739654-A1 (DE)
Title: Automatic brake device for cages
Inventor: FREISL PAUL-PETER
IPC: B66B5/18
Filed: 1987-11-23
Abstract: The conventional brake devices for cages of shaft hoisting installations, used in the event of rope breakage, are susceptible to faulty tripping and are therefore only reliable in operation to a limited extent. In order to obtain reliable braking and locking of the cage, the dead weight of the cage (4) acting fully on the hoisting rope (1) during normal travel is used (as shown in Fig. 1) via deflection pulleys (16) to hold the brake blocks (7), directed towards the guide rails (6), in a neutral position against the thrust of the compression springs (5). Instead of the rope tackle (2), a hydraulic transmission system with additional pressure-relief valve for manual brake actuation can also be used. In the event of a fall, the compression springs (5) are released and they press the brake blocks (7) against the guide rails (6), in which case any other locking devices can also be actuated instead of the brake blocks (7). <IMAGE>

Title: Arrangement of a drive system driven by muscle power for water craft, in particular for rowing (row) boats of different design
Inventor: WOELKY OTTO WERNER
IPC: B63H1/32
Filed: 1988-04-13
Abstract: The newly developed rowing system has no oars such as are presently customary, but a drive system operated by muscle power is actuated, as a result of which the hull of the boat is moved forwards by the pistons sliding backwards, accompanied by displacement of the water. In the process, the necessary stroke of the piston in the cylinder is enlarged by the slides of the rolling seat, in order in this way to achieve higher outputs. It is very important that the rowing device has a slide plate which thereby permits easy rowing. This novel rowing system has diverse boat fittings and forms which meet the adaptations for different sports and body dimensions. The hulls of the boats can be equipped with one or more cylinders which are to be designed in accordance with the expected body power. A boat hull consisting of two parts is considered as a special craft which has the stability of a catamaran. Outriggers (outlyers) which increase the stability of the boat can be attached to the hulls of the boats. The boat is steered by means of a rudder device. An additional version is a drive system by means of drive fins (flippers) for children and youngsters indulging in sport (see Fig. 9). <IMAGE>

Patent DE-3910149-A1 (DE)
Title: Lauter tun unit
Inventor: WOLFSEDER ALFONS
IPC: C12C7/14
Filed: 1989-03-29
Abstract: In a lauter tun unit, additional frame lautering surface area is created by subdividing the lauter tun into a plurality of chambers (10, 11, 12, 13) each of which have their own frame lautering surface (15, 16, 17, 18) at least at their outer periphery, which frame lautering surfaces are furnished with corresponding receiving chambers (19, 20, 21, 22) and outlet lines (23, 24, 25, 26). In this manner, to a certain extent internal additional frame lautering surfaces are made available and thus the lautering time is decreased. Without increasing the diameter, with constant charge size, the additional frame lautering surface (15, 16, 17) can be achieved by a stepped arrangement of the chambers (10, 11, 12, 13) rising towards the outside. A still further increase of the frame lautering surface can be achieved by radial separation of the chambers from each other, since then the internal periphery of the chambers can also be utilised for the formation of a further frame lautering surface. In this case, even the first wort can be led off bypassing the spent grains layer on upper frame lautering surfaces directly into a separate outlet chamber without passing through the spent grains layer. <IMAGE>
