Title: Control circuit for telephone exchange system - applies continuous pulses to control element and to selector stage and disconnects them when required
Inventor: DIRR JOSEF ING GRAD
IPC: H04Q3/42
Filed: 1977-07-12
Abstract: Equal centrally generated continuous pulses are applied to a control element (e.g. a first group selector) and to the selectro stage to be controlled. A comparator activates switches when a stored dialling criterion is equal to the number of dialling pulses allocated to it which are picked up from the continuous pulse generator. The control element has switches for continuous pulse connection and for delivery of a time position signal to the controlled selector stage, which activates switches applying the continuous pulses to the pulse evaluator. When a corresponding number of dialling pulses arrives at the comparator, it activates switches which switch off the continuous pulses and deliver a time position signal to the selector stage.

Used for prdn. of containers which flatten out during the dispensing of blood and other solns. under clinical conditions.
Patent DE-2912856-A1 (DE)
Inventor: WINKLER OTTO DR
IPC: F04B37/08
Filed: 1979-03-30
Abstract: In order to minimise the weight of the cryopump components (11-16) to be cooled and thus to reduce the cooling time, use is made of the fact that the thermal conductivity of metals, e.g. of copper or silver, increases with decreasing temperature. It is proposed to connect the kryosurfaces (11) to be cooled to the low-temperature stage (13) of the fitted multi-stage refrigerating machine (1) via a heat-conducting bridge (12) which is longer than a heat-conducting bridge (17) between the radiation shield (14, 15, 16) and a higher-temperature stage. Consequently, a lighter design and thus a lower heat capacity and a shorter cooling time can be achieved. The cryopump is particularly suitable for vacuum systems with a rapid evacuation/ventilation cycle. <IMAGE>

Title: Panic proof public emergency call box - uses ultrasonic echo sounder to hang up when caller leaves and monitored time switch
Inventor: SCHEEL KLAUS-DIETER ING GRAD
IPC: H04M11/04
Filed: 1979-03-30
Abstract: An emergency call box, connected to the public telephone system, has an alarm button, fixed microphone and loudspeaker, control circuits and an ultrasonic echo sounder to detect the presence of a caller. Pressing the alarm button automatically dials the emergency code and sends the call box identification. If it is pressed again, while the echo sounder still detects the presence of a caller, this is taken to mean that the first call has failed. The control circuit therefore first 'hangs up' and then repeats the automatic connection and dialling. If the echo sounder detects that the caller has left the box for more than a specified time, the control circuit automatically hangs up. The system includes a monitor unit (UEW) with two signal output lines (SAE1, 2) in parallel, each in series with a time-switch (ZSE1, 2) and a common driver circuit (TZE).
