Abstract: S. Ege - 8 ( Revision) Abstract of the Disclosure Paper and oil insulated high voltage power cables rely on maintaining the insulating oil under pressure for its proper functioning.  For this reason the cable installation includes a pumping plant or a pressure reservoir system.  In case of submarine oil filled power cables it is important to prevent water from penetrating the cable in case of ruptured cable, and this is obtained by creating a small outflow of oil at the rupture point.  A back-up system includes a gas driven membrane pump provided for ensuring such small outflow, and the proper functioning of the membrane pump is secured by introducing degasified oil at the drive side of the pump during the stand-by and test modes.

Abstract: ABSTRACT OF THE INVENTION    A hydraulic well jar of the type having a longitudi-nally slidable inner mandrel within an outer case, the inner mandrel having a hammer element thereon which im-pacts on an anvil element in the case. Hydraulic fluid is disposed between the case and mandrel.  Initial movement of the mandrel with respect to the case is impeded by a hydrau-lic fluid metering jet mechanism, which is bypassed as the mandrel reaches a predetermined point in its travel, al-lowing a sudden, more rapid movement of the mandrel, there-by generating a greater impact force.  The present invention comprises an improved fluid bypass design, as well as an improved mounting system for the hydraulic fluid screen and jet of  the metering mechanism. An improved seal arrangement between the metering mechanism, which is attached to the mandrel and the interior of the outer case provides greater seal life and better performance for the jar.

Abstract: PUMP AND ACTUATOR MECHANISM                       ABSTRACT         A pump is described in which a flexible enclosure defines a pump chamber and in which the contents of the pump chamber are expelled by movement of a pair of opposed pusher elements engaged with the enclosure.  The pusher elements are displaced by at least one pair of beam springs, each of which is pivotally supported at one end and is en-gaged with one of the pusher elements at the other end. The ends of the beam springs opposite the pusher elements are pivoted by acutation of symmetrical solenoid armatures, causing each of the springs to be stressed.  Relief of the spring stress forces the pusher elements toward each other. De-energization of the solenoid armatures permits the beam springs to pivot back to the original position upon filing of the pump chamber.

Abstract: Abstract:     Apparatus and Method for Reading and Writing Text Characters in a Graphics Display Apparatus and method for writing text characters to a raster scan video display operated in an all-points-addressable, or graphics, mode, and fox reading characters thus written.  A graphic video display buffer directly refreshes the display with graphics data received from a microprogrammed processor.  The processor writes a character to the display by selecting and loading into the graphics video display buffer a text character dot pattern retrieved from main storage, and reads a charac-ter previously written by comparing a dot pattern retrieved from the display buffer with dot patterns retrieved from main storage.  To write a character to the display in color, the graphic dot image of a selected character retrieved from main storage is expanded to a selected pixel and color format, and stored in the graphics video display buffer.  Text characters thus written in color are read by retrieving from the display buffer the expanded dot image, restoring the expanded dot image to its original form, and comparing the restored dot image with graphic dot images retrieved from storage.

Abstract: ABSTRACT      A method and apparatus are disclosed for address-ing a character generator memory containing symbols common to two or more languages in a common area of the character generator memory.  Symbols which are special to the particular language being displayed are stored in one of a plurality of special symbol areas of the character generator memory.  One of the special symbol areas contiguous with the common area is identified as a default symbol area.  The proper special symbol area of the character generator memory is selected by comparing the high order bits of a display character code with compare bits to determine whether a different special symbol area of the character generator memory is to be substituted for the default area contiguous with the common area.  If the compare bits indicate that a different special area of the character genera-tor is to be substituted, the high order bits of the display character code are not directly used to address the character generator memory but are replaced by sub-stitution bits to access that special symbol area unique to the language being displayed.

Abstract: ABSTRACT OF THE DISCLOSURE In a digital tester for evaluating electronic components, a local memory unit for each data channel in the tester is loaded with test vector information only in the locations of the memory relating to transitions that take place in the operation of the data channel.  In addition, a transition bit is stored in each memory location to signify whether the vector information in that location represents valid transi-tion data.  The transition bit is used to control the reading of information from the memory into a register that controls the flow of information in the data channel, so that only the valid transition vectors are fed into data channel control circuitry.  This pro-cedure substantially reduces the amount of data that must be loaded into the memory, and hence reduces the total time necessary to thoroughly test a circuit.
