Title: Inlet hopper of concrete pump - has sides extended with flexible pieces of varying elasticity for good connection to mixer chute
Inventor: RIKER RUDOLF ING GRAD
IPC: F04B15/02
Filed: 1979-12-15
Abstract: The pump has cylinders with reciprocating pistons which are fed from the base of an inlet hopper. The hopper has sloping sides (4). The height of the hopper is increased by extension pieces (1) fitted to the ends of the sloping sides (4). The extension pieces are flexible and their elasticity reduces from the fixed sides outwards.

Patent DE-3030028-A1 (DE)
Title: Prestressed concrete reactor vessel designed for overpressure - has extra external hoop prestressing in end slab zones
Inventor: SCHOENING JOSEF DIPL ING
IPC: E04H7/20
Filed: 1980-08-08
Abstract: A prestressed reactor pressure vessel, esp. for gas-cooled nuclear reactors, has its wall circumferentially prestressed by wound cables or wires. In the region of the top and bottom end closures this prestressing (9) is chosen so that the end slab gives rise to an internally convex stress dome (11). In one preferred arrangement (as illustrated), the prestressing increases by steps towards the top and bottom of the vessel, while in another variant it increases gradually. Used in particular for a gas-cooled, high-temp. nuclear reactor where a large number of standpipes and other ducts pass through the end slabs. The method enables the stress in the end slabs resulting from internal excess pressure to be compensated without special arrangements in these slabs. By increasing the hoop prestressing towards the ends, the inertia axis of the respective slab is displaced towards the axial centre of the vessel. In this way tensile stresses in the end slabs under excessive internal reactor pressure are avoided.
Patent DE-3030258-A1 (DE)
Title: Continuous treatment for vertical loops of fabric - uses upper or lower fabric loop guide rollers to control shrinkage
Inventor: TSCHIRNER WOLFGANG
IPC: D06B17/06
Filed: 1980-08-09
Abstract: The vertical loops of fabric passing through the processing zone are supported by upper and lower conveyor rollers. They are arranged in rows across the line of the loops, for the material to pass through the treatment fluid. The fabric shrinkage and fabric loop length is adjusted by moving rows of supporting rollers in relation to each other, and horizontal roller movement is supported by a lateral fluid flow, using a recirculating fluid pump to give a fluid flow corresp. to the height and width of the fabric loops. The horizontal fluid flow is also assisted by suction behind the last loop. The horizontal roller movement can also be provided by applying force to the rollers on an inclined plane. The appts. gives a low energy consumption coupled with high processing speeds, and an adjustable fabric shrinkage.
