Patent DE-2513575-A1 (DE)
Title: Transfer of heat from nuclear power station - to a remote steam generating system, using pressurised water as heat receiving medium
Inventor: SCHUELLER KARL-HEINZ
IPC: G21D5/08
Filed: 1975-03-27
Abstract: In an installation for the supply of steam connected to, but remote from, an atomic power station, with a device for heat transfer from the steam/water circuit of the power station to the steam/water circuit of the remote steam-producing installation (a) this heat transfer device consists of a surface heat exchanger in which the agent receiving the heat is water under pressure heated by steam obtained from the steam circuit of the power station (b) the pressure of the water in this heat exchanger is greater than that of the heating steams and selected so that no vaporisation of the water under pressure is produced in the heat exchanger and that generation of steam remotely from the power station is achieved by removal of the pressure on the heated pressurised water. Eliminates any risk of radioactivity in the remote steam-generating and using circuit e.g. due to a defect in the steam/water circuit at the power station, since the pressure of the water exceeds that of the heating steam from the power station.

Title: Adaptor ring for stacking round objects - has opposite axial collars of unequal diameters for object location
Inventor: MOHRMANN HANS-LUDWIG DR
IPC: B65D21/02
Filed: 1975-07-21
Abstract: An adaptor ring, made from plastic is used to stack objects which are of unsuitable shape for stacking. The ring has an internal radial flange (5) which is located in a central axial position. To one side of the flange, an axial collar (6) is formed which is used to locate the smaller diameter of the object that is being stacked. The collar is then wrapped over and taken axially back past the centre flange (5). This produces a second cylindrical collar (9) of increased diameter. The larger diameter of the object fits into this collar so that positive radial location between neighbouring objects is obtained.

Title: Blowout preventer for deep offshore wells - has auxiliary pistons exposed to surroundings for hydrostatic pressure compensation
Inventor: MANSHOLT FRITZ
IPC: E21B33/06
Filed: 1975-08-30
Abstract: Device consists of two pairs of hydraulically operated sliding jaws, one with semicircular cut-outs to seal against the periphery of the drilling tubes, and the other with straight-line joints. The piston rods are extended beyond the hydraulic pistons and are fitted with auxiliary pistons which are exposed to the surrounding sea water. This relieves the hydraulic drive of the hydrostatic pressure in great depths of water because the auxiliary pistons are designed exactly to counteract the force exerted by this pressure on the preventer jaws. This saves special expensive high-pressure accumulators.

Title: Integrated time delay circuit - modifies basic RC timing characteristic to provide approximately linear characteristic
Inventor: NEUMANN ERNST
IPC: H03K17/28
Filed: 1976-04-28

Title: Rattle-free take:up spool shaft seating - has axially spring loaded roller with radial supporting action and intentional misalignment between spool and pin centrelines
Inventor: FOEHL ARTUR
IPC: B60R22/34
Filed: 1976-05-04
Abstract: The design concerns a seat belt webbing take-up spool with loose seating on the shaft and an additional device to eliminate rattling noises due to the loose seating. For an absolutely safe operation of the take-up mechanism it is necessary that the spool should have a loose fit on the shaft. To take up the play between the spool bore an and the shaft the design proposes to provide the spool (2) seated in bracket (1) with the rattle-preventing device. One of the faces (5) of the spool extending beyond the bracket (1) has an opening (6) into which the tapered elastic ring (9) reaches. The ring rotates on a pin (8) fitted to cover (7), which is screwed to the side of bracket (1). The centreline of the spool and the centreline of the pin (8) are not in line, so that the tapered elastic ring rests with its tapered surface at one peripheral point of the bore edge (6).
