Patent DE-3042026-A1 (DE)
Title: High pressure valve for pneumatically fillable containers - uses e.g. magnets to hold flap valve on seat until complete venting is required
Inventor: LESK ADOLF
IPC: B65D90/34
Filed: 1980-11-07
Abstract: The high pressure valve closes automatically during pneumatic filling of containers from pressure vessels. The excess pressure after the beginning of the valve opening is reduced almost instantaneously by a largely unimpeded out-flow of the air. The flap opens completely after release from the valve seating, even if a reduction in pressure has already taken place. Magnets are used as a holding or press-on force for the flap on the valve seating.

Title: Metal clip with gripping surface matching angle - of wedge for fixing to base fitment in exchanger column
Inventor: STREUBER HANS-PETER
IPC: B01D3/32
Filed: 1980-12-05
Abstract: The base of an exchanger column is affixed to a holding ring inside the casing, or the parts of a base are connected together, by a clip with a projecting nose and formed as two connected sections made from sheet metal. The upper face of the nose forms a support, which may have a central projection. The upper ends of the sections are bent over transversely to form flat plates tilted outwardly down towards the column base. These two sections form a support for a wedge which is slid between them and a sheet metal base of the column. The angle between the tilted clip sections and the clip nose equals the wedge angle. At the opposite end of the clip from the nose are projections offset from the upper surface of the nose by the thickness of the metal to be inserted. Features of the wedge are also claimed. The wedge supports are more stable than known versions, occupy less space, and do not project enough to disturb liq. flow seriously.

Title: Method and device for producing a drive force in a closed loop
Inventor: ANDERSON MAX FRANKLIN
IPC: F01K9/00
Filed: 1981-10-22
Abstract: A method and a device for producing a drive force comprises a closed loop for the circulation of an operating fluid. Arranged in the loop is a drive machine, such as a turbine, to which the operating fluid is supplied in the form of a vapour, from an evaporator chamber which is partially filled with the liquid operating fluid. Arranged in the liquid operating fluid, close to the bottom of the evaporator chamber, is a condenser, through which the operating vapour leaving the turbine is passed for cooling and condensation, the latent heat of evaporation being transferred into the liquid operating fluid in the evaporator chamber. The liquid operating fluid from the condenser is pumped to a heating device, such as a solar array, to be heated without evaporation. The heated liquid operating fluid from the heating device is transferred into the evaporator chamber for evaporation. The heat of the liquid operating fluid inside the evaporator chamber is absorbed, as latent heat of evaporation, by the liquid operating fluid as it evaporates, in order to cool the liquid operating fluid in the evaporator chamber. The cold, liquid operating fluid at the bottom of the evaporator chamber assists the extraction of heat from the turbine outlet by the condenser at the bottom of the evaporator chamber. The turbine can be used to drive a generator which can supply electrical power to an electric motor. The system is suitable for use in a vehicle in which a solar array is arranged on the vehicle roof for heating the operating fluid.
