Title: Double exposure facility for self processing camera - has manual plunger to displace cassette during shutter setting
Inventor: SACHS GUENTER
IPC: G03B17/52
Filed: 1979-07-28
Abstract: The double exposure facility for a self processing camera has the cassette displaced by a manual plunger during the shutter setting, and film index action. This moves the edge of the film pack away from the transport rollers and prevents the exposed film from being dragged through the process rollers. A manual override button presses the shaft through a light proof hole. The inside end of the shaft rests against one edge of the cassette and pushes it against the aligning springs. The system is simple and requires no complex exposure control.

Title: Hollow core for casting - with closed filler openings by solidifying residual amt. of moulding mixt. through heat
Inventor: HERZOG HEINRICH
IPC: B22C13/08
Filed: 1980-07-12
Abstract: Hollow cores, e.g. for the casting of the inlet manifold of a 4-cylinder internal combustion engine, are produced by upturning the mould in which heat has produced a solid wall lining of the moulding mixt. of sand, resin and hardener, so that the loose sand can run out through the filler openings. A small amt. of sand is retained by a heated plate which causes this mixt. to solidify and close up the core cavity. Hollow cores can now be used in the flat casting position where thin walls are stressed less highly, without the need for a labour-intensive closure operation.

Title: Method for producing water for the water injection system of a hydrogen-consuming internal combustion engine
Inventor: LOEFFLER RAINER DIPL ING
IPC: F02M25/022
Filed: 1981-01-23
Abstract: In the operation of internal combustion engines using hydrogen, under certain operating conditions water is added to the air-hydrogen mixture to be burnt. This water is generally obtained from the exhaust gases by condensation. At times, however, the quantity of water thus producible is not sufficient. The carrying of a supply of water must be ruled out owing to the risk of frost in winter. In accordance with the invention an additional quantity of water is obtained at the time it is required by evaporating water from a solution containing antifreeze and condensing the water vapour. The engine cooling water is expediently used as the solution containing antifreeze. Any excess of water produced in the condensation of water from the exhaust gases can be used for re-establishing the original water concentration of the solution containing antifreeze.

Patent DE-3106188-A1 (DE)
Title: Oxygenator membrane
Inventor: STROH NORBERT DIPL ING
IPC: B01D61/38
Filed: 1981-02-19
Abstract: The oxygenator membrane for oxygen and carbon dioxide exchange has a very low diffusion resistance, direct gas-blood contact as in the case of bubble oxygenators or pore membrane oxygenators being avoided. This is achieved by the use of a highly porous membrane which is closed by a very thin polysiloxane layer (0.1  mu m) on one side or by filling the pores with a blood substitute fluid such as fluorocarbons or physiological saline solution. The oxygenator membrane can also be used for the germ-proof screening and aeration in the clinical field, e.g. operating theatres and incubators.
