They cannot slip and the lock is simple to release by turning a lever.
Patent DE-2653289-A1 (DE)
Inventor: ZURCHER JEAN-FREDERIC
IPC: G10L25/90
Filed: 1976-11-24
Abstract: A detection circuit for the significant peaks of a speech signal, comprising first and second detectors respectively for detecting the positive and negative peaks of said speech signal. Each of these detectors is followed by a peak charging circuit comprising a first integrator having a relatively large discharge time constant and a comparator comparing the detected speech signal and the output signal of said first integrator. Each peak charging circuit comprises in addition a second integrator having a relatively small time-constant. The discharge of the first integrator is effected up to a voltage equal to the output voltage of the second integrator, and the discharge of the second integrator is effected down to a voltage depending on the output voltage of the first integrator. The two integrators of each peak charging circuit provide a non-exponential decreasing signal which has an inflection point following a significant peak in the original speech signal.

Title: Solar heat collector - prevents burst panels and condensate by vents and silica gel in e.g. styrene! foam
Inventor: LORENZ JOHANN
IPC: F24S10/50
Filed: 1977-07-29
Abstract: A solar heat collector is fitted with a safety feature against bursting by pressure caused by high temps. The absorber unit now rests on a filling of e.g. styrene foam with open cells. A small hole in the base panel of the absorber unit connects the space between it and the transparent cover to a section where the foam is replaced by silica gel. The pan carrying the styrene foam has on the opposite side a large hole which communicates with atmosphere. The pressure can thus be equalised without risk of condensate forming and reducing the efficiency, because the silica gel prevents it.
