Title: Synchronisation of distant digital equipment - employs returned clock pulses to block clock counter unless pulses are coincident
Inventor: VERNEZY JACQUES
IPC: H04L25/49
Filed: 1975-12-19
Abstract: Synchronisation of digital equipment located some distance from the principal equipment is obtained by compensating for transmission time delay. Clock signals are returned by the remote equipment to block the clock counter except when there is coincidence. Clock pulses are applied through a gate (7) to a binary counter (8) for application to a bipolar pulse generator (10). These signals are gated (26) with signals from a logic gating circuit (25) for transmission to the remote equipment via a two way cable. Returned signals enter an integrity detector (17) whose output is applied to a coincidence gate (23) with sync. frame signals (2). A bistable (24) ensures that the counter is blocked when non-coincidence occurs.

Title: Controlled damage of semiconductor surface - uses tungsten balls and acoustic vibration of wafer to cause damage for experimental testing
Inventor: SCHWUTTKE GUENTER H
IPC: H01L21/322
Filed: 1976-03-12
Abstract: A method is described of inducing known and controlled damage on semiconductor wafer surfaces to enhance the study of damage characteristics both before and after semiconductor device processing. A number of tungsten balls (32) are placed on the surface to be damaged and the wafer (26) is subjected to acoustic vibration. The wafer is bolted (30) to the end of a P.V.C. tube having a loudspeaker driver at its other end. Ideally the loudspeaker emits noise tuned to the resonant frequency of the wafer. By placing two wafers in the tube, faces almost touching and with the balls between the surfaces, both surfaces can be damaged by the vibrating balls. Two loudspeakers may be used, one at each end of the tube and operating in antiphase. The damaged wafers may be used in device manufacture, employing the stress relieving property of the damaged surface during high temperature processes.
Patent FR-2347523-A1 (FR)
Title: Perforating well casing and fracturing producing formation - by pumping abrasive fluid through nozzles pressed against the casing
Inventor: TAGIROV K M
IPC: E21B43/112
Filed: 1976-04-05
Abstract: Jet nozzles are pressed tightly against the casing hile abrasive-laden fluid is pumped through the nozzles at a const. rate and at pressure not less than the formation fracture pressure. The fluid erodes the casing locally until perforations of a diameter virtually equal to the diameter of the flow passages in the nozzles are formed, whereafter the flow rate of the fluid is varied as necessary to produce a const. pressure within the formation not less than the formation fracture pressure. Fractures can be caused to extend in preselected directions, and since perforations are formed which have a preselected size and shape the entire kinetic energy of the abrasive-laden fluid becomes available for establishing the fractures. Where fractures are required at several levels, these can be formed during a single trip into the well.

Title: Lift safety device operating if speed is excessive - has fuse melted or broken by excess battery charging voltage and holding brake shoes free
IPC: B66B5/04
Filed: 1976-10-04
Abstract: The fuse is connected between a battery in the cage and a cylindrical copper body containing two permanent magnets, so as to hold the magnets inside the body. When the fuse blows, the magnets move outwards, causing brake shoes to press against the rail stopping the lift cage. The battery is charged by dynamos driven by wheels running against a lift shaft rail, one working during descent and the other during ascent. Excess downward speed generates a charging voltage via the fuse sufficient to blow it. A further safety device is provided by a rope reeved from a drum round a pulley and to the fusebox cover, and which has a set maximum unwinding speed. When this is exceeded due to excess cage speed, the rope pulls the fusebox free and breaks the fuse.

Patent FR-2342567-A1 (FR)
IPC: H01R12/55
Filed: 1977-02-24
Abstract: The object of the process is to achieve economical mass production of such arrangements in that case where the spacing of adjacent conductor tracks situated in one plane is large compared to the spacing of conductor tracks situated opposite one another. This is achieved by a non-metallic soldering agent or curable binder (10) being admixed with metal particles (20) whose largest extent corresponds approximately to the spacing of the conductor tracks (5', 6') situated opposite one another. The contact bridges are particularly suitable in the fabrication of liquid-crystal cells. By means of said contact bridges, all the connections of the cell can be arranged on one cell board, which is particularly advantageous for multiplex-driven liquid-crystal cells. The binder (10) with the metal particles (20) at the same time serves as a sealing web of the cell.
