Title: STD telephone exchange - has timing stage triggering alarm if not reset within given time due to fault in selection processes
Inventor: RENGER WOLFGANG
IPC: H04Q3/42
Filed: 1978-09-15
Abstract: The telephone exchange has each connection request issued by the request line from a register passed as control pulse to an output line shared by all groups of registers.

Title: Bubble rise rate measurement device - has measurement tube with vertically spaced sensors and microcomputer
Inventor: GLASMACHER PETER DIPL ING
IPC: G01V8/20
Filed: 1979-03-30
Abstract: A device measuring the rate of rise of bubbles in a measurement tube is applicable to lead-acid electrolyte specific gravity measurement. It enables the introduction of air or gas bubbles of defined size into a measurement fluid and the subsequent accurate measurement of their rise speed. Gas is bubbled into the tube at an opening in its base. The rate of rise and the vertical acceleration of the bubbles are derived from the outputs of sensors placed at intervals up the tube. Each sensor produces a signal when a bubble passes it. The tube is filled with measurement fluid via a suction tube connected to the opening. The time relationships of the sensor signals are processed into density and/or viscosity values by a microcomputer.
