Abstract: Abstract of The Disclosure An improved planar contact array switch having reduced susceptibility to electrostatic discharge includes a printed circuit board which carries at least one switch contact foil pair.  Sandwiched between the circuit board and an insulative overlay is a dome-shaped disc which, when depressed, completes an electrical circuit between the switch contact foil pair.  Bordering the periphery of the printed circuit board so as to bound the area occupied by each of the switch contact foil pair is a ground foil which advantageously is provided with at least one inwardly ex-tending charge conductive foil which runs adjacent to each of the switch contact foil pairs for conducting any electro-static discharge which penetrates the overlay within the area bordered by the ground foil.  To facilitate the conduc-tion of electrostatic discharges to the perimeter ground foil through the charge conductive foil, a spark gap is provided between each of the switch contact foil pairs and the charge conductive foil so that an electrostatic dis-charge may jump the spark gap and be conducted via the charge conductive foil on the ground plane to circuit ground.

Abstract: ABSTRACT OF THE DISCLOSURE        A device for mixing materials in a container, said device providing rotation of the container about two axes perpendicular to one another.  The device comprises a first frame mounted rotatably on a pedestal and a second frame mounted rotatably within said first frame and provided with a wheel-like element being in engagement with a circular raceway so positioned that the second frame rotates about a second axis which is generally perpendicular to the first axis.  The design of the frames makes it possible to position one or more containers within the second, internal frame so that additional centripetal acceleration of the material to be mixed is created whereby vibration and balance problems are reduced.  The device thus provides greater versatility and simpler design than that of known devices.

Abstract: ABSTRACT: Very large scale integrated circuit subdivided into isochronous regions, method for the machine-aided design of such a circuit, and method for the machine-aided testing of such a circuit.         A very large scale integrated circuit comprises a number of function blocks which are synchronized by relevant clock signals. Each function block forms an isochronous region so that the delay times of the signals within the relevant function block can be negligibly small with respect to the gate delay tubes. Each function block is paired with at least one other function block in that the pair is connected by an information connection and by at least two synchronization handshake lines for transporting synchronization signals despatched by each function block of the pair to the other function block of the pair so that an asynchronous information transport is obtained. One or more of the function blocks comprises an information connection to the environment. As a result of this set-up, the circuit can also be tested and designed per function block.

Abstract: Abstract A method for impregnating wood by means of an impregnating liquid, wherein the wood (l) is placed in an airtight, pressure resistant impregnation tank (2) from which the air has been completely or almost completely evacuated, and wherein the impregnating liquid (17), following its intro-duction into the tank, is subjected to pressure.  All or almost all of the air and/or gas content of the impregnating liquid is removed prior to its introduction into the impregnation tank (2).  The impregnating liquid is intro-duced under completely airtight conditions, whereby the liquid (17) is completely or almost completely devoid of gas and air when impregnation takes place, i.e., upon penetration of the liquid into the wood (1).            An apparatus for carrying out the method comprises an impregnation tank (2) for containing the wood (1) to be impregnated, wherein the tank has the necessary equipment for producing a vacuum in the tank as well as pipes connecting it to a storage tank (11) containing impregnating liquid (17) for supplying the impregnating liquid to the impregnation tank (2) following evacuation of the latter tank.  In connection with the storage tank (11), equipment is provided for completely or almost completely evacuating the air or other gas from the tank and from the impregnating liquid (17).  In connection with the impregnation tank (2), equipment is provided for increasing the pressure in the tank under completely airtight conditions.  The increase in pressure can be brought about by providing a means for reducing the volume of the impregnation tank, e.g., by arranging one or more inflatable, elastic bladders (3) in the tank (2) or in a liquid-conducting pipe connected to the tank.  The pressure increase can also be produced by introducing additional liquid by means of a pressure pump provided between the storage tank and the impregnation tank.

Abstract: CABLE CLOSURE Abstract A closure for a cable splice includes two mating covers and two end plate assemblies.   Longitudinally extending joints between the covers are filled with sealing gaskets.  Also a peripheral channel in each end late is filled with a circumferential gasket.  The covers are asembled together to enclose the end plate asemblies with the gaskets in the joints therebetween.  Then, the covers are moved toward each other and secured together by moving a continuous wire support frame which is disposed on each side of the closure and which a plurality of latching fingers mounted pivotally therealong to cause each latching finger to snap past a center bistable position into locking engagement with an aligned seat along the closure.  As the covers become secured together, the longitudinal and circumferential gaskets are cause to seal their associated joints.  Also, at each confluence of the covers and each end plate assembly, the longitudinal gaskets which span across weakened longitudinally extending portions of the circumferential gaskets become disposed in compliant engagement thereith to form seals.  The wire suport frame is sufficiently resilient to cause the forces which are applied to be adequate under a wide range of temperature conditions to maintain effective seals.
