Patent DE-2833441-A1 (DE)
Title: Ignition system for IC engine - has electronic control device which suppresses ignition signal at usual instant and generates spark at later instant
Inventor: SCHMIED HELMUT
IPC: F02P5/155
Filed: 1978-07-29
Abstract: The IC engine ignition system has a control device delaying the ignition time in accordance with the engine speed. The control circuit is an electronic device by which the ignition signal at the instant (t6) not affected by the control device is suppressed when the engine speed is in a specified lower range. The system ensures that a spark is ignited at a specified later instant (t'8) after the ignition signal appearance.

Title: Spring-mass accelerometer using piezoelectric tuning fork assembly - consisting of four piezoelectric elements of identical characteristics joined together in pairs by carrier
Inventor: FICK FRANZ DIPL ING
IPC: G01P15/09
Filed: 1978-10-16
Abstract: A spring-mass accelerometer is such that the displacement of the mass against the force of the spring is a measure of the applied acceleration and is converted into an electrical signal. It reduces the incidence of spurious voltages indicating accelerations not actually existing which can arise in piezoelectric types. Four piezoelectric elements of identical mechanical characteristics are joined together by a carrier (1) in pairs (2, 3) to form a tuning fork like arrangement electrically connected. An a.c. voltage of frequency corresp. to the mechanical natural frequency of the elements is connected to the first pair (2). The second pair (3) produces a voltage whose phase angle w.r.t. the input voltage is a measure of the acceleration. Because a.c. voltage stimulation is used there is no rest condition in which the null voltages can occur.

Title: Electronic flash connection for piezoelectric flash camera - has shorting switch for piezoelectric crystal when shutter is fully open
Inventor: HAEBERLE KARL-HEINZ
IPC: G03B15/03
Filed: 1979-04-11
Abstract: The electronic flash connection is for a camera with a piezo-electric flash generator (6) which has the electronic flash connected via plug-in contacts (5) to the synchronised shutter control. A shorting switch (4) over the piezo-electric generator fires the flash after the switch is closed by the shutter drive. The electronic flash is only fired when the shutter is fully open, and after the switch is operated. No special time delays are required, with the short electronic flash easily accommodated in the long exposure time selected for piezo-fired bulbs. The piezo-electric generated charge is damped in the electronic flash gun through low input impedance. The piezo-electric charge does not control the electronic flash and the camera requires no complex conversion circuit to alter the piezo charge.

Title: Storage method for digitised video camera signals - has image digitised and entered into memory at rate synchronised with camera scanning rate
Inventor: GAUBE WILFRIED DIPL ING
IPC: G06V10/10
Filed: 1979-04-17
Abstract: The scanning and digitisation of objects, e.g. documents, is followed by storage in a digital RAM and uses a video camera system. The data entry with memory is synchronised with the camera. The output signal from the video camera is processed by an amplitude discriminator stage that provides comparison with a threshold value. The digitised value is clocked into a shift register at a rate fixed by a clock generator. A second comparator stage provide a line pulse frequency discriminator and outputs a synchronisation signal. The signals change the state of a counter that provides an address to the memory into which the accumulated image values are entered.

Title: Sepg. oil, water and sludge from a mixt. - arising in garages, workshops etc., using separator with large capacity tank with outlets for oil and water
Inventor: HAMMERSCHMITT NIKOLAUS
IPC: F02B3/06

The settled sludge is not contaminated by oil, and occupies a relatively small space in a single tank.
Patent DE-2951640-A1 (DE)
Title: Cooling plate for blast furnace or similar plant - where iron is cast round uncoated pipes made of iron nickel chromium alloy so good heat transfer is obtd.
Inventor: HEINRICH PETER DR ING
IPC: C21B7/10
Filed: 1979-12-21
Abstract: Metal pipes, which will be used for the circulation of a coolant, are laid in a mould filled with molten iron so pipes are embedded in a cast iron plate. Pipes possess no surface coating, so they are in direct contact with the cast iron; but no metallurgical reactions occur between the pipes and the iron to impair mechanical strength or heat transfer from the plate to the coolant circulating in the pipes, when the plate is mounted on a furnace. Pipes are pref. made of an alloy contg. 30-63% Ni; and cooling air is pref. fed through the pipes during and/or after the casting of the iron round the pipes to make the plate. Metal pipes cast into cooling plates are normally coated to prevent reactions between the pipes and the cast iron; but the coating impairs heat transfer. The invention employs uncoated pipes (3) so heat transfer from the plates to a coolant is improved.
