Abstract: ABSTRACT        A circuit for use in a digital data receiver to recover a clock signal, of variable rate, from the signal received by the receiver.  A typical digital data receiver includes demodulating or other means for converting the received signal to a binary data signal having a characteristic which changes in a manner corresponding to transitions in the digital data received.  The invention provides circuit means for recovering a clock signal from the binary data signal where the data rate may vary over a substantial range.  The clock signal recovery circuit utilized a logic transition detector to produce a narrow pulse at each data transition in the binary data signal.  The pulses, which contain harmonic frequencies at the clock rate of the binary data signal, are up-converted or mixed with an electrical signal from a frequency synthesizer. The signal resulting from this up-conversion is filtered by a narrow-band filter to produce an electrical signal at a pre-determined intermediate frequency.  The output signal from the frequency synthesizer is mixed with the signal from the narrow-band filter, in a down-convertor circuit, to produce a reference signal having a frequency proportional to the clock frequency of the binary data signal.  The frequency synthesizer has a variable frequency output determined by the setting of a data rate selector.  An electronically controlled oscillator produces a signal having a frequency proportional to the binary-data-signal clock rate.  The oscillator is in a phase-lock loop including a phase detector supplied with the reference signal having a frequency proportional to the clock rate of the binary data signal.

Abstract: INVENTION:          SPIN POT         INVENTORS:          JAMES JUDSON COOKSEY and GARLAND LINWOOD TURNER            ABSTRACT OF THE DISCLOSURE      A spin pot, for the extrusion of one or more ends of multifilament, synthetic fibers is disclosed.          The spin pot features a top cap comprising a flow inlet passage and between 3 and 80 substantially identical polymer delivery channels.  The flow inlet passage brings molten polymer to an area the central axis of which substantially coincides with the central axis of the top cap.  The delivery channels communicate with the flow inlet passage in this area and branch radially therefrom  at substantially equal intervals to open at the lower surface of the top cap into a distribution space.  The cross-sectional area of each of the delivery channels remains substantially uniform along its respective length.  The ratio of the number of delivery channels to twice the distance in inches between the central axis and the inner edge of any one of the delivery channels at the lower surface of the top cap is between 1 to 2 and 3 to 1, and the delivery channels open in the peripheral 50% of the lower surface disposed above the internal wetted area of the distribution space.  The sum of the cross-sectional areas of the delivery channels is substantially the same as the cross-sectional area of the flow inlet passage.  Improved sealing characteristics for the spin pot are provided by the design of the top cap and the breaker plate.

The spinning solution is extruded into as aqueous coagulating both having a temperature of 0° to 45°C, and after removal therefrom is dipped in water having a temperature of 30° to 100°C.  Then free water is removed from the fiber and the fiber is subjected to freeze-drying under vacuum.  The coated fiber is prepared by immersing the above-mentioned fiber in a bath containing 0.2 to 5% by weight of the polymer dissolved in a solvent which is a non-solvent for the cellulose derivative.

Abstract: ABSTRACT OF THE DISCLOSURE      A process for producing petroleum from subter-ranean formations is disclosed wherein production from the formation is obtained by driving a fluid from an injection well to a production well.  The process involves injecting via the injection well into the formation an aqueous solution of lignosulfonate salt as a sacrificial agent to inhibit the deposition of surfactant contained in a micellar dispersion (microemulsion) on the reservoir matrix. Normally the process would be carried out by first injecting the lignosulfonates into the formation through the injection well and following them with a micellar dispersion which may contain lignosulfonates.  The micellar dispersion would then be followed by a drive fluid such as water to push the dispersion to the production well.                             I

Abstract: Abstract An ink supply system for an ink jet, or an array of ink jets, is disclosed in which an on-off valve is interposed in the conduit between the ink reservoir and the droplet forming nozzle, and a second source of ink under pressure is connected through a normally closed valve to the conduit between the nozzle and the on-off valve.  To initially prime the nozzle, the on-off valve is closed, a vacuum pulled on the nozzle, and the valve opened to fill the conduit and nozzle.  To reprime or clear obstructions such as dirt particles, the on-off valve is closed and the normally closed valve briefly opened to send a pulse of ink to and through the nozzle.  With both valves closed during shipping or storage, the likelihood or ink being dislodged from the nozzle or conduit so as to deprime the nozzle is minimized.

Abstract: LIQUID-METAL PLASMA VALVE CONFIGURATIONS             ABSTRACT OF THE DISCLOSURE      Liquid-metal plasma valve has an anode, a condenser and a force-fed liquid-metal cathode.  These bound the interelectrode space through which the plasma jet acts during conduction. The cathode directs the plasma jet to impinge on an inclined surface which acts as he anode.          The inclined surface reflects the particles to the condenser when the anode is noncondensing, but when the functions of anode and condenser are combined, the inclined surface of the condensing anode traps the jet particles.  When the anode is noncondensing, in some cases the condenser and anode are at the same potential and in other cases the condenser and cathode are at the same potential.  Cathode, anode and condenser are shaped to minimize the transit time of jet particles from emission to condensation.

Abstract: HIGH VOLTAGE CIRCUIT INTERRUPTER SWITCH ARRANGEMENT ABSTRACT: A high voltage circuit interrupter is enclosed within an integral insulating housing that includes an operating mechanism enclosing portion, an insulator portion, and a muffler portion. The inte-grally formed insulating housing is formed to provide a groove in one interior wall of the operating mechanism enclosing portion and a similar groove is formed on the housing cover immediately opposite the groove in the wall so that a portion of the operating mechanism can ride in the grooves thereby eliminating certain internal metallic components. The operating shaft of the inter-rupter is hexagonal in cross section thereby elimi-nating the need for special machining, keys, and cross pins to attach operating levers to the shaft. Operating triggers having round bearing surfaces are inserted over the ends of the hexagonal shaft to provide a smooth running bearing fit with openings in the housing wall. A unique locking arrangement is utilized to lock the lever arm of the operating mechanism to the hexa-gonal shaft. Also, a bayonet type connection at the exhaust end of the interrupter unit permits a rain cap to be easily and conveniently attached to the inter-rupter unit.
