Title: Can or drum changing device for fiber spinning plants
IPC: B65H75/16
Filed: 1974-11-11
Abstract: A can or drum changing device for fiber spinning plants in which multi-fiber yarn supplied continuously from a textile finishing machine is fed into cans or drums for intermediate storage.

Both cans or drums are lifted before starting the changing procedure, and both lifting devices have a common pivot so that during the changing procedure, both cans approach each other and are freely suspended without interferring with each other. When the multi-fiber yarn from the textile finishing machine has filled one can, the continuous yarn is then transferred to the juxtaposed empty can, both cans being placed so close together at that time that the yarn cannot drop between them. The filled can is then lifted from the rotary table and the empty can is lowered onto such table.

Title: Stabilised supply for antiskid traction control - uses galvanic isolation element e.g. transformer to eliminate interfering transients
IPC: B60L3/10
Filed: 1977-04-15
Abstract: The electric traction control incorporates a non-skid circuit with rectifier, monitoring stage, voltage stabilised supply and output amplifier.

Title: Security system.
IPC: G08B13/26
Filed: 1979-11-28
Abstract: A security system of the bridge circuit type has in one of its arms a conducting element whose impedance is to be monitored and in its other arms reference and/or compensating elements, for detecting an unbalance of the bridge resulting from a sudden change in the impedance of the conducting element. At least one of the reference elements has a variable impedance. The phase shift of the signal obtained at the output of the bridge circuit is detected, due to the drift of the bridge circuit, with respect to the A.C. supply frequency. The detection signal is then used for compensating the drift by acting on the reference element having a variable impedance in order to bring the bridge circuit back to balanced condition.
