Patent DE-2346754-A1 (DE)
Title: Appts. for reducing pipe mains hammer blow - is for power station boiler water feed systems using three-way valve
Inventor: HAEFELE CARL HEINZ MOENCHENGLA
IPC: F16K47/02
Filed: 1973-09-17
Abstract: Power stations have rapid acting reversing valves for regulating feed water passing through preheaters. These give rise to pressure waves which travel up the feed pipe and can cause much damage. The patent covers a system in which the three way cock is first reversed. At the same time a stopping element closes relatively slowly. This is followed by the closing of a throttling mechanism in an exhaust circuit which short circuits the closure of the three way cock, i.e. into the pipe under pressure. This lessens considerably the risk of hammer blow.
Patent DE-2347823-A1 (DE)
Title: Peltier element cooled detector system - has semiconductor detector for measurement of beams

The warm side of the Peltier element is in thermal contact with a heat emitting housing and the cold side is in contact with a mount for the semiconductor detector. One front of a good heat conducting cylinder supports the semiconductor detector and the other front of the mounting is connected to the cold side of the Peltier element directly or via a cold plate. The detector system is almost independent of the location of energy or cooling and measuring position.

(because silicon carbide is more resistant to oxidn at high temperatures than is graphite).
Patent DE-2363825-A1 (DE)
Title: Light structure roof heat insulation under snow - with insulating layer's heat penetration reduced under loading to allow thawing
Inventor: TRAEBING ERNST
IPC: E04H15/02
Filed: 1973-12-21
Abstract: This is esp. suitable for tents, air-supported hangar-type buildings and other very light structures, the purpose being to reduce heat insulation in snow-covered and icy conditions so that the snow etc melts and no snow clearance is necessary, avoiding constant monitoring of snow-loading on top. An insulating layer of soft material or other closed and open air cells is applied to the outer membrane under a weather-protective layer. This layer is compressed at a predetermined loading level, thus reducing the insulating effect; warmth flows to the snow which melts so that the insulating layer can revert to its normal shape, and resume its function.

Title: Catalytic exhaust gas purifier for motor vehicle engines - has a spring between the catalyst housing and channel walls
Inventor: KRUEGER HERMANN
IPC: F01N3/28
Filed: 1974-02-15
Abstract: The catalytic exhaust gas purifier has a housing within the exhaust pipe which accommodates a catalytic exhaust gas purifier. The catalyst housing is protected against excessive heating and hence against excessive thermal distortion.

Patent DE-2451540-A1 (DE)
Title: Easily inflatable hollow body with skeleton - uses skeleton to form basic shape before supplying air to excess pressure
Inventor: NAPIERSKI REINHARD
IPC: A47C27/08
Filed: 1974-10-30
Abstract: The inflatable hollow body is to be increased in size by means of an inflatable skeleton which as it is opened out draws in the fluid medium e.g. air. For example in the case of an air bed or rubber dinghy the skeleton which has only a comparatively small volume is inflated whilst one or more inlet valves to one or more main chambers of the mattress etc. are opened so that air can automatically flow in. The inlet valve of the hollow skeleton is then closed and the main chamber pumped up until the desired excess pressure is achieved. The tiresome pumping up of a flat hollow body into the inflated finished article is thereby considerably shortened. This system can also be applied to piston-cylinder units.
Patent DE-2452034-A1 (DE)
Title: Self adjusting circular valve plate - has slotted pivot pin locations for axial seal wear compensation
Inventor: SCHULMEYER WILHELM
IPC: F16K1/22
Filed: 1974-11-02
Abstract: A circular valve plate (1) rotates about two diametrically opposite pivot pins (6). The pins are located in the valve seat ring (5) which also houses the flexible valve seal (12). The pivot pins have rectangular heads (8) which are placed in axial location slots (7) in the valve plate lugs (4). When the valve seal wears, the valve plate is able to move axially so that enough seal pressure is obtained from the fluid acting on the plate area. This is possible because the pivot pins are able to move relative to the plate.

The projection is separated by U-shaped cut-outs (20), the rounded ends of which face towards the centre of the closure. The wire closures are connected to each other in a long strip, which may be rolled up.
