Patent DE-2326124-A1 (DE)
Title: Animal feeding stuff sterilization - with automatically controlled valve for boiler and vacuum pump
Inventor: KRICK GERD DR ING
IPC: A23K30/00
Filed: 1973-05-23
Abstract: Animal feeding stuff which is sensitive to oxygen is sterilized in a first evacuation stage followed by a second steam germicidal stage. The time at which the first stage is terminated is fixed as a function of type and quantity of feeding stuff in such a way that the pressure at the changeover moment is certain to lie above the cavitation pressure of the vacuum pump. This eliminates variable evacuation times so that equipment in a mass production flow line can be utilized to better advantage.

Title: Toxic gases eliminator from exhaust gases of I.C. engines - has a multistage thermal reactor and is connected to a turbocharger
Inventor: WOLLENWEBER JUN WILLIAM EDWARD
IPC: F01N3/24
Filed: 1973-08-31
Abstract: The system used for reducing the toxic components in the exhaust gases of internal combustion engines is connected to a turbocharger. The total oxidation reaction in the reactor is improved by mixing with incompletely oxidised hydrocarbons. The turbocharger turbine is powered by hot exhaust gases which pass between the stages of the thermal reactor. The turbocharger turbine uses the energy released by the reactor for driving the compressor. This arrangement improves the thermal efficiency of the engine cycle and full chemical reaction is possible for achieving complete combustion of the exhaust gases. The cylindrical reactor is connected to the engine exhaust system. The gases flow along a helical path through the internal chamber openings and through the channels between a shell and the outer wall. The helical path ensures sufficient dwell time for further oxidation of incompletely burnt hydrocarbons. The thermal reactor stages and the turbine stage of the turbocharger are joined into a common housing.

Title: Bang bang valve with temperature sensor - sensor actuates valve with magnetically controlled open and closed positions
Inventor: SEIFFERT GUENTER
IPC: F16K31/08
Filed: 1973-11-10
Abstract: The valve comprises a magnetically positioned rubber valve head engageable with a valve seat formed between inlet and outlet ducts. Magnetic positioning is achieved by a pair of axially spaced annular permanent magnets between which there is located an axially movable iron core to one end of which the valve head is resiliently mounted. A capillary sensor moves the core between its two positions by causing small axial movements of a plunger which bears on the core via two coil springs. Separation of the core and one permanent magnet occurs when the compressive force applied to the respective spring exceeds the magnetic force. Production of an air gap between the core and the permanent magnet reduces the magnetic force and promotes bang bang operation.
