Title: IC engine fuel economy carburettor - uses accelerator pedal release to cut fuel supply
Inventor: SCHAEBEL HEINRICH
IPC: F02M3/02
Filed: 1977-07-23
Abstract: The fuel saving system is esp. for 4-stroke petrol engines or Diesel engines. Release of the accelerator pedal causes the fuel supply to be blocked. The supply is reinstated, when a certain torque range is reached, and when the accelerator pedal is depressed. The impulse for the fuel supply blockage is caused by load reversal, e.g. during deceleration of the vehicle; it is used when the engine does not drive, but retards the vehicle. When a certain RPM is reached, resp. is fallen below, the fuel supply is re-connected, and remains connected to prevent stalling of the engine.

Title: Auxiliary trigger unit for TV service oscilloscopes - provides frame and line triggering and has voltage multiplier to derive power supply from input signal
Inventor: WEISS CHRISTOPH DIPL ING
IPC: G01R13/32
Filed: 1977-08-05
Abstract: The trigger circuit for use with an oscilloscope consists of a voltage multiplier stage (SV) to which is fed the composite television signal derived from a suitable point in the receiver. This signal is also fed to an amplitude discriminator (AS). Part of the signal is transformed up, rectified and smoothed for use as a supply voltage for the discriminator and a multivibrator (AM). The synchronisation pulse is filtered out in the discriminator and fed to an integrator (IN) and to a differentiator (DI). The integrated signal reaches a peak value during the frame blanking intervals and triggers the multivibrator if a certain threshold value is reached. Every other frame synch, pulse is suppressed. The output of the differentiator delivers positive and negative pulses at line rate.

Title: Foamed plastics moulding - in which the article is stabilised by the passage of pressure gas through the article
Inventor: TEUBERT JOACHIM ING GRAD
IPC: B29C67/20
Filed: 1979-03-21
Abstract: In moulding a foamed plastics article of the type in which expansible beads are expanded in a mould by the action of a hot gas, the article thus formed is stabilised by passing a pressurised gas through it, pref. whilst still in the mould. Pref. the pressure of the stabilising gas, which may be air, does not exceed the pressure of the expanding gas, which may be steam. If stabilisation is effected in the mould then the mould may be opened and closed several times during the stabilisation. The invention avoids the prior art use of having to spray cooling water into the mould halves to stabilise the article. The mould may thus avoid the use of slits and be merely of porous sintered material.
