Title: Compensation pressure meter using heat fluid - has thin walled capillary connected to container with large surface area
Inventor: ROEVER MARTIN DR ING
IPC: G01L19/06

Title: Self-cleaning dust filter for gases - having pair of reverse set cleaners connected to single fan with traverse drive on jets and rotating diverter valve
Inventor: WUKOJEWITSCH HANS
IPC: B01D46/12
Filed: 1979-03-15
Abstract: Filter removes dust from gas streams esp. air and has a set of filter bags stretched on frames. These are cleaned by a reverse purge system which operates from a pair of reverse jets which move backwards and forwards over the filter outlets to blow back the bags. These jets are driven from a single fan which feed the jets through a rotating diverter valve. This can divert the purge air to either of the jets or allow the jets to vent. The position of the jets on their traverse and the valve position are coordinated. Used for filtering air streams and gives a construction which is cheaper, it uses less energy for filter cleaning, the efficiency is higher and the mfg. cost lower.

Title: Panic proof public emergency call box - uses ultrasonic echo sounder to monitor behaviour of caller
Inventor: SCHEEL KLAUS-DIETER ING GRAD
IPC: G01S15/88
Filed: 1979-03-30
Abstract: The emergency call box is connected to the public telephone system and has an alarm button, a fixed microphone and loudspeaker, control circuits and an ultrasonic echo sounder to detect the presence of a caller. Pressing the alarm button closes the exchange line loop. A relay detects the loop current, irrespective of polarity, and maintains the loop after the button is released. After a short time delay, an automatic dialling circuit sends first the emergency dialling code and finally the call box identification code. The call is terminated by opening the loop relay when the echo sounder detects that the caller has left.

Title: Circuit with sensor near vehicle accelerometer pedal - discontinues fuel supply to engine when vehicle is coasting or being braked slowly from high speed
Inventor: MAYER KLAUS
IPC: F02M3/045
Filed: 1979-06-15
Abstract: The circuit has a sensor near the vehicle's accelerator pedal and indicating when the pedal is depressed. Break contacts measure the speed of the crankshaft.

The lever (30) is seated in pivot (32) which is fitted on the disc (20) with a guide shaft (21) which performs translatory movements in guide bore (1) of the valve body (1). The translatory movements of the disc (20) are produced by the swivelling transfer element (50) with the shaft carrying a spherical part (53) freely movable in all directions in the socket (55). The end of the shaft carries a tip (60) which is in continuous contact with the edges of the template.
