Title: Telephone equipment to transmit signals of specified duration - which are in accordance with input commands using capacitor charge time
Inventor: LAGROU JAAK DIPL ING
IPC: H04Q1/30
Filed: 1974-08-16
Abstract: The start of charging period is determined by the beginning of signal transmission. A first winding (I) of a second relay (AF2) and a second winding (II) in opposition to the first and in series with a capacitor (C), are in parallel with a first relay (AF1), so that capacitor (C) begins to charge through the second relay (AF2) winding (II) simultaneously with the first relay (AF1) energising. When the relay (AF2) excitation through its winding (II) becomes very weak i.e. when capacitor (C) is fully charged, its excitation through the winding (I) becomes predominant and the first relay (AF1) circuit is broken through contacts (4af2 or 5af2 or 6af2 or 7af2), thus determining the end of signal transmission.

Title: Filament track profile for sliding clasp fastener - combining good head support with extended anchorage loops
Inventor: FROEHLICH ALFONS
IPC: A44B19/40
Filed: 1975-09-10
Abstract: Complementary track patterns are made from continuous thermoplastic filaments. The interlocking heads are formed by bends in the filament profile normal to the plane of the track. One supporting leg of each bead is extended to provide an elongated loop which can be secured by an array of threads for holding the track to a support tape. The other supporting leg of each bend is part of a short loop linked to the next head. Appts. is described for winding pair os tracks alternately about a common coaxial mandrel and outboard mandrels for the extended loops of each individual track. When two tracks are engaged, each of the interlocking heads is in effect supported by three short profile loops, one being its integral support and the other being the short legs supporting each of the adjacent heads. The fastening is thus inhibited from twisting and disengaging. The extended loops provide adequate anchorage area.

Title: Correlator for contactless speed measurement using 3 sensors - has extra function generator between integral regulator and voltage to frequency converter to extend range
Inventor: MESCH FRANZ PROF DR ING
IPC: G01P3/80
Filed: 1975-10-03
Abstract: A correlator used in the contactless measurement of speed of moving objects uses three measurement sensors. It is designed for an extended measurement range. The sensors produce signals delayed w.r.t. each other according to the time taken to traverse the distance between them. The signals are combined with time reference signals from shift registers and processed in differentiators and logic elements to produce three correlation function signals. The correlation signals are added and conducted as an input to an integral regulator which produces a signal whose frequency corresponds to the speed. To expand the measurement range a function generator is inserted between the integral regulator and the voltage-to-frequency convertor, which may be replaced by a voltage-to-period converter.
