Title: Yarn feed device having reserve winding on drum - with movable guide to prevent or allow yarn to be pulled axially from the drum to provide two feed rates
Inventor: JACOBSSON KURT ARNE GUNNAR
IPC: D04B15/48

Title: Interference proof security device with variable code - transmitted across secure area and checked at receiver against code by using various transmission techniques
Inventor: MUELLER KLAUS-PETER
IPC: G08B13/183
Filed: 1974-11-23
Abstract: The interference proof security device uses a variable pulse rate encoded signal transmitted by some means typically ultrasonic, or light beam across the secured area, and which checks the continuously received signal against the transmitted signal. The device is an improvement on traditional equipments of this kind which use a constant code which though simple, can be interfered with. Basically, a clock generator producing pulses at irregular intervals, feeds a transmitter over a pulse shaping network. The transmitter typically transmits a light beam across some secure area. A receiver picks up this irregular signal and a block of electronics consisting of flip flops, a gate, a counter and decoder with various outer gates, compare the transmitted and received signals. Taking into account suitable delay, and also ignoring small disturbances, the circuit raises an alarm if the correct coded signal is not received.
