Patent DE-2708776-A1 (DE)
Title: Hybrid circuit connector system for rectangular component - uses corner connectors with component in any orientation between triangular ends of two conductors
IPC: H01R12/57
Filed: 1977-03-01
Abstract: The hybrid circuit has two conductors (2) each extended at its ends to give a larger area which is triangular in shape (3). There is a rectangular component (5) which has two contact surfaces (8) at opposite ends that contact these two extended triangular regions. The triangular regions and the component contact surfaces are tinned to facilitate soldering. The advantage lies in allowing rectangular components to be mounted in any orientation. A variety of different circuit arrangements may be used with the rectangular circuit components arranged in different orientations.

Title: Shredded sugar beet extraction tower - with rectangular feeder slot at angle to tower radius in tower bottom plate
Inventor: DIETZEL WALTER
IPC: C13B10/10
Filed: 1977-04-02
Abstract: An extraction tower for shredded sugar beet is a vertical cylinder with a revolving shaft, equipped with radial conveyor paddles and distributors at the bottom. The mixture of shreds and sugar beet juice is fed in the tower bottom through a rectangular slot between the conveyor shaft and the tower shell at an oblique angle to the tower radius. a ring main (in case of several slots) or a feed pipe supply the mixture to the slot. This ensures a uniform distribution of the shred and juice mixture even for towers of very large diameter and capacity. The feeder system is not expensive to produce and does not interfere with the juice extraction.

Title: Introduction of inherent stress to bending girder and stressed bar - using mutually cancelling normal force constituents with common member end anchorage
Inventor: BORSDORF HEINZ DIPL ING
IPC: E04C3/04
Filed: 1977-05-02
Abstract: Inherent stressing conditions are applied to flexural girders and normally stressed bars. Simultaneous introduction of tension and pressure constituents is carried out via bars or stress members, into girders made of various materials, such as wood, steel, concrete or plastics. This is done to generate inherent stressing moments, with normal force constituents largely cancelling each other out. The members are end-anchored at selected points, in shared anchoring units. Pressure stress members comprise single or groupled rods and wires, led in sheathing tubes or between points of support so as to leave min. room for lateral play. On initial introduction of pressure, these members are supported against each other or against the tube walling to retain a stable position under increased loading.

Patent DE-2756642-A1 (DE)
Title: Grinder disc movement control - has return movement halted on engagement contact width falling below predetermined value
Inventor: ABBUEHL HERMANN
IPC: B24B47/20
Filed: 1977-12-19
Abstract: The system controls movement of a grinder disc in relation to a workpiece between the quick-traverse and the finishing operation. The return movement of the disc away from the work following quick-traverse is halted at the moment when the degree of engagement in the work falls below a predetermined value, typically zero. The degree of engagement can be measured by the amount of grinding noise, the torque applied to the disc or the quantity of sparks generated. A further alternative is to use the amount of bending of a machine component.

Title: Lifting platform control system ensuring horizontal position - has synchronised hydraulic systems with equal volumes on both piston sides
Inventor: WEBER HANS HEINRICH DIPL ING
IPC: B66F9/12
Filed: 1978-04-20
Abstract: The constrained control system ensures horizontal holding of a lifting platform carried on an extended arm. The swivelling of these arms is controlled by two servosystems. The platform of the lifting frame is held in any position of the swivelling arms in correct horizontal position without any correction operation. The two servo systems are alike and the piston movements of both arrangements are synchronised. The volumes on both sides of the pistons, in proportion to the distance of the piston movement, displace equal cylinder volumes. The synchronised piston movement of both servo systems is ensured by equal cross section of piston rods on both sides of the actuating pistons within cylinders.

Title: Semipermeable membrane unit - having set of spacers and membrane with appropriate holes which can be combined in modular form
Inventor: BONIN WULF VON DR
IPC: B01D63/08
