Title: Alarm signal transmission device - uses existing network for television signals with oscillator working within frequency band of cable
IPC: H04N7/173
Filed: 1975-01-23
Abstract: The alarm system uses the coaxial cables which carry the signals for a communal aerial TV system and there is an oscillator which is operated by the closing of the alarm contacts. The frequency of the oscillator is chosen so that it falls within the band of frequencies used for the TV visual and audio signals, and the alarm signal is conveyed by the type of modulation of the signal carried by the network of cables. The signal then acts as a monitoring signal. The alarm and monitoring systems may be connected at any point of the network of cables.

Patent FR-2289812-A1 (FR)
Title: Electric traction with hydraulic torque converter - has mechanical clutch to bypass torque converter above set speed
IPC: F16H61/14
Filed: 1975-10-31
Abstract: The battery driven DC transmission has a constant current pole supply for speeds up to a set level, after which any increase in speed is obtained by reducing the field current. This eliminates any high current control circuits which are usually required in conventional designs to vary the pole current. Speed control from starting to the set speed is obtained by a variable hydraulic torque converter. At the set speed the torque converter is bypassed by a hydraulically controlled mechanical clutch. This eliminates transmission losses in the torque converter when it is not being used. The control of the clutch and the torque converter is via a hydraulic pump with the clutch engaged when the pump output is zero, so that the pump can be disconnected at the higher speeds, thus saving power.

Title: Automatically threading a spinning or twisting ring traveller - double carriage mounted arms push thread into positioned traveller
Inventor: GROSSI OSCAR
IPC: D01H15/00
Filed: 1976-02-09
Abstract: An assembly for automatically threading an end of yarn into the traveller of a ring spinning or twisting frame, includes a first carriage on a stationary oblong frame movable on guide rods to and from the ring on which the traveller is positioned centrally beforehand, a second carriage mounted on lengthways running guides secured to the first carriage, and two long arms with hooked ends straddling the ring, linked by a spring pulling them together, and assembled on a horizontal shaft supported by the second carriage. A separate drive moves the shaft and the arms via a rack, through a predetermined angle to the axis of shaft, whilst the arms can further be turned on pivots at their near ends, on axes vertical to the long axis of shaft, so that they open and close with a tongs-like action, as they swing on the shaft. On the first carriage, a pressure cylinder imparts reciprocating motion, and serves, during the first section of the forward motion, to regulate the movement of the arms, lowering them, and effecting the forward motion of the second carriage during the second section of the forward moition. There is a cam arrangement effecting the opening and closing of the arms. Automates the threading of the raveller, working in conjunction with the positioning device described in DT 2606553.
