Title: Switch=off method for IC engine - closing throttle valve but delaying closure for fuel valve
Inventor: MUELLER ECKART DR
IPC: F02B3/06
Filed: 1990-04-05
Abstract: The engine has an air inlet manifold valve (11) to operate as a throttle valve and a fuel injection system (3) closely spaced to the inlet manifold. When the engine is switched off, the shut-off control (5) switches off the air inlet by closing the throttle valve and shuts off the fuel feed via a delay circuit (24). This prevents engine juddering as the engine slows. The controlled pressure changes in the engine during switch-off provide a vibration free run down, especially for diesel engines. The throttle valve shut-off is relay operated (12) with a sliding valve (14) to connect to either atmosphere or to a vacuum line. ADVANTAGE - Controlled shut-off; improved comfort.

Title: Using single shape-memory effect in cold formed alloys based on nickel@-titanium@ - by cold forming alloys into strip or wire homogenising at 750-950 deg. C, quenching to give martensite structure etc.
Inventor: KLOSS HUBERT
IPC: C22F1/00
Filed: 1990-10-31
Abstract: A process using the single shape-memory effect (SME) in cold formed Ni-Ti based alloys is new. In the method, the alloys are cold formed into strip or wire, homogenised at between 750-950 deg C, quenched to give the metal martensite structure, and then further subjected to between 12-40% deformation. Thus, the SME achieved is related to the degree of cold forming imposed on the alloy., USE/ADVANTAGE - Has particular speciality uses in surgical implants, special tube joints etc., The process expands and broadens the range of using single SME in alloys. In an example, a compsn. (%wt.) Ni 54.6,Ti 45,4 was cold formed into a cylinder, homogenised for 30 mins, at 850 deg C then quenched in water to give a martensite structure. Next, it was cold formed (25% degree of deformation) to produce wire 1 mm dia. which was then heated up to 200, 300, 400, 500 and 800 deg.C. The SME occurs at temps above the transition temp. of 163 deg C. It was found that after cold deformation of 25% and at 2000 deg C the SME was 12%, and this could be increased to 40% after heating to 500 deg. Further temp. increases led to increased SME but not to so marked an exten

Title: Rapid removal of cyanide from ground-water - by aeration, enrichment with nutrients, filtration then return to the soil
Inventor: KNAPP ARNO DR
IPC: B09C1/10
Filed: 1991-01-12
Abstract: Removal of cyanides dissolved in groundwater comprises pumping the water from a source well (3) to the surface where it is enriched with oxygen and nutrients then returned to the soil through at least one fixed bed filter (7).
