Patent FR-2228730-A1 (FR)
Title: Mechanisable glass cutter - imparting series of shock in vicinity of scored line on glass sheet
IPC: C03B33/10
Filed: 1973-05-08
Abstract: Glass sheets are cut by (a) marking with a cutter to trace a scratch on the surface using a cam, (b) producing a crack along the scratch, and (c) flexing the sheet to break the surplus glass away. In the second of these steps, a series of successive and opt. simultaneous shock are applied to the glass on the unscratched side along a line approx. parallel to the line of the scratch. When the scratch is sharply curved, the distance of the blow from the scratched line is decreased, and the weight of the blow is reduced. This process can be mechanised.

Filed: 1973-07-18
Abstract: The system is based on multiple clock generators for reset and trigger pulses, threshold detectors for monitored parameters, logic interlock units based on magnetic cores with reset windings and out put relays. Each of the four magnetic cores in a two out of four logic unit has four reset windings any one of which resets the core with positive direction pulse. At least one of the other three reset windings is simultaneously excited in the opposite direction to compensate for this.

Title: Centripetal extruder with interrupted spiral ribs - generating positive pumping pressures for e.g. cable coating
IPC: B29C48/46
Filed: 1974-03-13
Abstract: In a centripetal extruder, each of the opposing disc daces features >=1 array of surface ribs defining >1 series of concentric, partially spiral channels which positively pump matl. towards the extrusion axis. Used esp. for coating cables passing as cores through a coaxial passage through the extruder. Reduction of the matl. path area by the interrupted spiral ribs increases the back pressure available at the outlet die. Decompression zones permit devolatilisation if desired. Device is more efficient than a single screw Archimedean extruder.

Title: Automatic control for dipping headlights - having time delay circuit operating with light intensity monitoring photocell
IPC: B60Q1/14
Filed: 1974-06-28
Abstract: A photocell is positioned at the front of the vehicle to monitor the light intensity of approaching vehicles. When that intensity exceeds a set level then the headlamps are dipped. A time delay circuit, comprising RC elements delays the dripping operation for two to six seconds so that once the lights are dipped they cannot be restored to full beam immediately, which could happen if the approaching vehicle dips its lights and reduces the intensity on the photocell suddenly. The output of the time delay circuit is fed to an amplifier to operate the switching relay.

Title: Moving body speed loss detector - has capacitive memory with controlled charge loss and has voltage threshold detector
IPC: G01P13/00
Filed: 1975-12-24
Abstract: The device is used to detect the loss of speed or stopping of a mobile body. It has a position detector (D) which detects a code inscribed on the mobile body, a capacitive memory with controlled charge loss associated with a voltage detector threshold, and a charge loss accelerator for the capacitive memory. The capacitive memory has only one stable logic state due to the controlled charge loss. The unstable state is regenerated by the electrical pulses from the position detector when the moving object is in motion. The position detector may be an electrical contact under a sealed bulb which is sensitive to a magnetic field. The charge loss accelerator increases its effect when the frequency of excitation pulses increases.
