Abstract: The grinding aid (1) is a device for simplifying the re-grinding of twist drills (8) to be carried out by hand. The device essentially consists of a holder (2) into which the drill (8) can be inserted in such a way that its end face to be re-ground is aligned in a predetermined position with a face (9) of the holder (2) which is to be held parallel to the grinding surface (14) of a grinding wheel (15). In effect, the holder (2) forms a template (9,10) for arranging the drill (8) in the correct position in relation to the grinding wheel during re-grinding.

IPC: H01L29/74
Filed: 1980-11-29
Abstract: In order to achieve reverse voltages of at least 800 V in both directions in thyristors which are manufactured using planar technology, an n-type base region (7) is formed with sufficient thickness to be able to accommodate the space charge zones encountered at such voltages without the risk of premature breakdowns. The thickness (W3) of the base region (7) is at least approximately 110  mu m, and this results in a total thickness of the thyristor (1) of at least 200  mu m. In order, nevertheless, to make possible the diffusion of the p-type insulating regions (8) through the entire peripheral section of each device (1), which takes place before the separation of a silicon single crystal chip (2), a groove pattern (9) is etched in the silicon. The grooves have a depth (H) of approximately 80  mu m. They make possible the diffusion of the peripheral sections (8) in an expedient manner and permit easier separation of the devices (1). <IMAGE>

Title: Emetteur-récepteur et son utilisation dans un réseau de télécommunications
Inventor: DEMAN PIERRE
IPC: H04B1/46
Filed: 1980-01-08
Abstract: La présente invention concerne les postes émetteurs-récepteurs. L'émetteur-récepteur selon l'invention est commandé par un dispositif d'alternat automatique (6,9) afin de permettre le passage en émission uniquement lorsque des signaux vocaux sont à transmettre et que le récepteur (10) n'en reçoit pas. En émission, l'émetteur délivre pendant les périodes d'activité vocale, des signaux à haute fréquence, modulés à amplitude constante, et ne délivre rien en dehors de ces périodes. En réception, des moyens de détection (20, 21 et 22) des transitions rapides d'amplitude des signaux reçus et un circuit logique (26) permettent de commander la fermeture d'un interrupteur électronique (28) pendant les périodes d'activité vocale afin que la sortie du récepteur ne délivre que des signaux vocaux. Un discriminateur parole-bruit (24) classique valide cette décision. Le récepteur comporte en outre un amplificateur (12) des signaux reçus dont le gain est commandé par une boucle de contrôle automatique. La valeur de la constante de temps de cette boucle est commandée pour être faible pendant les périodes d'activité vocale et forte en dehors de ces périodes. Application aux réseaux de transmission.

Abstract: At the underside of a substantially U-shaped support or carrier formed of steel there is affixed an intermediate element or part formed of an electrically conductive material, for instance copper or a copper alloy. This intermediate element carries at its bottom face or surface two contact supports or members formed of a suitable material, for instance AgCdO. At the ends or end faces of the U-shaped support there are attached arc conducting elements formed of a ferromagnetic material, for instance steel. The arc conducting elements protrude away from the base portion of the U-shaped support in the direction of the contact supports and extend laterally thereof up to the region of their contact surfaces. The arcs arising during contact opening directly transfer or shift from the contact surfaces to the arc conducting elements, without the arc base points migrating laterally from the contact supports to their connection locations. The contact supports or members as well as their connection locations are thus protected against destruction by the arcs.

Abstract: A combined ignition control and injection valve operating circuit has an inductor (20) connected in (series or) parallel with the ignition coil (16) so that it carries current whenever an output transistor (11) of an ignition control circuit (10) is on. 
     A thyristor (24) connects the inductor (20) to an energy storage capacitor and turns on each time the transistor (11) turns off to create an ignition spark. The capacitor is thus charged up and the stored energy is discharged through a triac (26) into an injection valve solenoid (27) to speed up current growth in the latter on each energisation thereof.

Abstract: An electro-hydraulic proportional actuator includes a piston and cylinder(10) which is positioned hydraulically by fluid flow through two solenoid valves (15, 16) operable by an electronic control system. An operator control (34) provides an input voltage (V 1 ) representing a desired piston position and a transducer (35) generates a voltage (Vv) representing the actual piston position. The difference between the input and output voltages generates a difference or error signal (Ve2) that is fed into a feedback system including a sample-and-hold circuit (36). A clock logic system (39,42,46,54) is provided for transmitting the signal from the feedback system to the solenoid valve at predetermined intervals to activate either valve to move the actuator piston in either direction or to activate both valves to hold the piston at a desired position.

Abstract: A pavement breaker including a mobile carrier vehicle is disclosed. A beam (38) is provided having a resonant frequency with a pair of nodes spaced from the input and output ends of the beam and anti-nodes at each end and at the center. An oscillator (46) is fixed to the input end of the beam to vibrate the beam at at least near its resonant frequency. The beam is mounted to the carrier vehicle at the node near the input end of the beam. A weight (54) is superimposed over the beam at the node near the output end and has a bearing surface adapted to bear downwardly against the beam at that node. The weight is coupled to the vehicle to control the vertical position of the weight. A tool (76) depends from the output end of the beam, and strikes the surface (22) on which the vehicle rests at the vibration frequency of the beam as the tool vibrates responsively to vibrations of the beam. The reaction force generated by the tool is substantially absorbed by the weight and not transmitted to the carrier vehicle. The tool is preferably provided with three segments, a middle segment which lies substantially horizontally while the beam is stationary, and forward and rear segments which are inclined upward. The forward section allows the tool to follow the ground, while the orientation of the real tool enhances the breaking action of the tool.
