Title: Performance booster for gas or vapour compressor - has spring loaded pushrod actuated valve between inlet and collector chamber
Inventor: ALMOND DAVID RICHARD
IPC: F04B49/22
Filed: 1973-10-19
Abstract: Performance booster system is e.g. used in compressors for refrigerating systems. The control system used for the performance of the compressor prevents excessively low inlet pressure. The control system has a valve actuated by a pushrod and this valve is used to separate the inlet channel from the collector chamber or to connect this channel with the collector chamber. A channel is provided in the valve for equalising pressure to that of the collector pressure. A spring preloads the pushrod to keep the valve closed, and solenoid is used to actuate the pushrod against the spring load into open position.

IPC: C02F1/44
Filed: 1974-10-01
Abstract: Desalination plant for sea water and other liquids comprises an ultrafiltration membrane for effecting mechanical fine filtering by means of atmospheric pressure, followed by a membrane for filtration by true osmosis. A pressure difference is obtained by means of a U-pipe in which accumulated liquid is pumped out on one side after the U-pipe has been closed at the apex of its curved portion by a porous membrane. The vertical water column in the pipe pushes the salt soln. through the membrane, the salt proportion being retained up to molecular size. Several U-pipes are mounted one behind the other, and behind them is the osmosis filtration plant.

Title: Process evaluating foil capacity efficiency - determines impedance relationship to comparison foil
Inventor: SCHNELL JOACHIM DR RER NAT
IPC: G01R27/26
Filed: 1974-12-11
Abstract: Process and associated set-up evaluate capacitor efficiency of foil which is shaped for electrolytic capacitors.

Title: Emergency shutdown valve for reactor steam line - closes if leak occurs and partially reopens to relieve pressure build-up
Inventor: SCHABERT HANS-PETER DIPL ING
IPC: G21D3/04
Filed: 1975-04-30
Abstract: The Parent Patent describes a nuclear reactor with a rapid shut-off valve in the steam line (2) leading from a steam generator (1) out through the containment shell (towards the right) to a turbine. The valve cross-section is equal to the steam line cross-section. This valve is driven by pressurised fluid to the closure position, as shown in full lines, if a leak occurs in the steam line. The valve is actuated by a two-piston system, connected to the upstream side of the steam line, so that if the steam pressure rises again the valve partially opens to less than half the flow cross-section of the steam line, to permit limited escape of steam without damage. Only one of the pistons is connected rigidly to the valve plate whereas the other piston is coupled to it only over part of the stroke. In the Patent of Addition the pistons associated with the valve plate are actuated solely by a controlled release of pressure. The pistons are pref. both tubular, one inside the other. Used for a pressurised water reactor. The valve is actuated solely by steam, without other pressurised fluid. In normal operations all parts of the valve are in contact with steam, thus minimising temp. differences.

Title: Stator for flexible helical rotor pump - is constructed in sections which are forced together by adjusting screws
Inventor: DAUNHEIMER ERICH
IPC: F04C2/107
Filed: 1975-07-04
Abstract: Pump has a helical screw rotor turning eccentrically inside a female helically shaped elastomer stator (2). This is held within an outer stator housing (1). Inlet and discharge end flanges (3,4) are clamped over the two ends of the stator housing (1). The stator housing (1) is made in sectors which join together to form a cylindrical casing but leave gaps between them. They are kept together by adjusting screws (9) running through threaded holes (10) in the end flanges (3, 4) and pressing on the sectors of the stator housing. As the stator wears with use the screws are tightened and close up the housing so as to compress the stator more to reduce its diameter to compensate for the wear. This increases the useful life the stator.
