Patent DE-2406466-A1 (DE)
Title: Airtight clamping method for membranes - membrane edge lies on shoulder to be pressed by circular spring clip
Inventor: OTTENI HERMANN
IPC: F16J3/02
Filed: 1974-02-11
Abstract: The membrane which is e.g. used as a membrane valve is supported by its edge on a step in a cylindrical bore. A ring with spring tabs is pushed into the bore so that due to the deformation of the tabs a spring force is exerted against the inside face of the bore. The tab-ring is pushed so far into the bore that a rim on the ring engages with the edge of the membrane and secures it in position. When the ring is in position, the tabs face upward at an angle against the bore. Any force which attempts to push the ring out of the bore jams the tabs harder against the inside of the bore.

Title: Vehicle anti-collision radar - avoids false danger alarms from reflections from roadside reflectors
Inventor: HAHLGANSS GUENTER
IPC: G01S13/937
Filed: 1974-02-22
Abstract: An instrument for the determination of the differential velocity and the distance of an object in front of a moving vehicle uses a centimeter wave pulsed signal and a receiver for the returned echoes, whith an evaluation circuit determining the distance from the time difference between transmitted and returned signals from the distance signals, together with a further differentiator followed by a threshold switch which cuts out the main differentiator if the output of the additional differentiator exceeds a pre-set value. The effect is to prevent a false warning of excess speed if a temporary flse echo is received from a close roadside reflecting object.
