Title: Seal for removable cover - having circular section metal sealing ring and spring tensioner
Inventor: MEIER HERBERT DIPL ING
IPC: B01J3/03
Filed: 1976-10-29
Abstract: Seal is for removable cover on pressure vessels, the cover having a projecting lip with a circular rim on the end. A seal chamber is formed between the inner wall of the vessel and the lip into which a sealing ring fits. This is held in position by screws above, and the upwards thrust of the vessel pressure on the cover causes this to contact the seal. The ring is made of metal and has a circular cross section. A prestressed spring element is inserted between the tensioning screws and the seal ring. This can be a plate spring. From the projection on the cover which forms one sealing surface to the inner surface of the vessel is an acute angle and the circular seal is pressed into this wedge shaped slot. It has a flat upper surface which contacts the compression ring above. Used on medium pressure vessels esp. nuclear power plant, operating at pressure and temp. where conventional compressible seals are subject to attack from materials in the vessel. This seal overcomes thse problems and gives prolonged usage, esp. for relief valve cover seals.

Inventor: BORCHARD HEINZ
IPC: B29C43/52
Filed: 1976-12-30
Abstract: Mfr. of gramophone record discs in a heatable and coolable mould comprises keeping the temp. of the mould surface, during moulding, in the centre portion (about 120mm dia.) of the intended disc, lower than outside this centre portion, whilst the mould is being heated. At the same time, a temp. gradient is maintained from the rim of the mould inwards. The heating phase is terminated when the rim of the mould has reached max. temp. During the cooling phase, the mould surface temp. is adjusted so that it very slowly drops, from the centre towards the outside. Arrangement enables gramophone record discs to be mfrd. at high output rate whilst minimising generation of "frozen-in" stresses, strong molecular orientation and incomplete relaxation of the moulding cpd. As a result, dimensionally stable prods. are obtd.
Patent DE-2720324-A1 (DE)
Inventor: FUNK BURKHARD
IPC: H01H9/36
Filed: 1977-05-06
Abstract: The DC fast-action switch having at least one stationary contact (4) and one moving contact (5) is provided with a conductor (6) which is arranged opposite the fixed contact (4) and is stationary. The said parts (4, 5, 6) are arranged between two spark-protection plates (1), each spark-protection plate (1) having at least one U-shaped or V-shaped metal part (3) in the arc ignition region. The arc is diverted onto the metal part (3) during switching off. Partial arcs occur in each case between the stationary contact (4) and the metal part (3), as well as between the metal part (3) and the stationary conductor (6), on both sides of the contact pair (4, 5). This arrangement ensures that the U-shaped or V-shaped metal part produces fast and reliable extinguishing of the arc which occurs during switching off, the stationary conductor (6) contributing to the magnetic blasting of the arc. Problem-free switching off of both large and very small currents is possible, without a separate magnetic blasting device. <IMAGE>
