Patent FR-2260892-A1 (FR)
Title: DC to DC converter with power amplifier - has output isolated from input by means of transformers
IPC: H02M3/337
Filed: 1974-02-13
Abstract: The DC input to this convertor is applied to a transformer by a push-pull pair of power transistors. The output is rectified, filtered and connected to a regulation stage. This compares the output to a reference and regulates a blocking-oscillator whose output is also rectified and filtered. This resultant level is compared to a sawtooth and the differential ramp-voltage is used to produce a variable-width pulse. A push-pull amplifier is driven by that variable-width pulse and, in turn, controls the power transistors. The use of transformers completely isolates the input and output and overcomes the variability problems of previous designs using photo-coupled diodes for regulation.

Title: Machinery for sorting various objects - uses sliding pushers moving across segmented conveyor belt
IPC: B65G47/84
Filed: 1974-04-04
Abstract: The conveyor is made of transverse segments (16). Pushers (19) can move across the conveyor, short shafts (21) with enlarged ends (23) attached beneath the pushers passing between segments and guided by transverse strips (22). The transverse movement is caused by longitudinal bars (24) beneath the conveyor, moving on gear driven chains, which engage against the enlarged heads (23). A motor (32) drives a shaft (33) running the length of the machine. Electromagnetic clutches are used to activate selected lengths of the longitudinal bars (24) as required. When an object on the conveyor approaches a container at the side, the necessary clutch is engaged and the object pushed off. An angles bar close to the lower length of the container returns the pushers to the starting position.

Title: Magnetic recorder and playback unit - has recording and playback head with guide pin moving over recording medium surface in guide groove(s)
IPC: G11B21/04
Filed: 1974-08-26
Abstract: The recording and playback head is moved continuously over the magnetisable surface by means of a guide pin at a specific distance from the head by the rotation of the recording medium and the incline of the guide groove. A jib arm supporting the guide pin is movably supported by a joint. The bearing pressure of the pin is determined by a weighting element, while the bearing pressure of the recording and playback head is determined by its dead weight in conjunction with the supporting arm of the head unit. The guide pin may be eccentrically mounted in its weighting element, and the head and pin spacing may be adjusted by rotation of the element.
