Abstract: METHOD FOR IMPROVING MESSAGE RECEPTION          FROM MULTIPLE SOURCES                    Abstract of the Disclosure A method for improving reception of a data word to be sent from an origination station to a destination station comprises generating and storing error correction functions for a message word including the data word.  Error correction functions are transmitted only if the message word is invalidly received thus offering improved performance over a conventional retry scheme. Interleaving reduces susceptibility to burst noise and altering carrier frequency for retransmissions minimizes effects of noise. The method is especially useful in a system comprising a central receiver and a plurality of physically separated remote transmitters wherein electrical path quality between receiver and transmitters may independently randomly vary.

Abstract: ABSTRACT         Pressure Retaining Enclosure An  enclosure     around a substrate    such as a telecommunications cable is made pressure retaining by the provision of re-entrant seals    , generally V-shaped in cross-section, that are positioned at the region where the enclosure is bonded  to the substrate pressure within the enclosure thus tends to open the V rather than put the bond in peel. The re-entrant seals may be cut-to-length in the field and a leak path through the resulting open end      avoided by using pressure (P) within the enclosure to close the open end or to balance pressure across it.

Abstract: NAIL GUIDE AND SET            ABSTRACT OF THE DISCLOSURE     A tool for countersinking nails into a workpiece has a base member, which is formed of resilient material, and has a generally flat bottom section resting on the workpiece.   A metal guide is mounted in the base member.  The guide has a central opening for receiving a nail in its bottom.  A rigid cap member on the base above the guide has an aperture through it, and a nail set extends partially upward out of the aper-ture in the cap and extends into the opening in the guide above the nail for transmitting impact from a hammer on the nail.  The bottom of the guide member is recessed from the bottom surface of the base so that the metal will not contact the workpiece.  The cap has a greater diameter than the guide so that if the cap is struck when the bottom or the nail set is below the top of the workpiece, an impact on the cap is not transmitted to the guide but will be absorbed in the resilient material of the base.  A nail starting section integral with the  base  member  extends  laterally  outward.   It  contains starting holes that grip nails initially.  A slot extends from each opening to a larger opening, and the tool can be pulled over a nail until the nail is in the larger opening where it can be removed from the nail.

Abstract: ABSTRACT:          Nuclear magnetic resonance apparatus with surface coil detection.         For measurements with increased accuracy in a nuclear magne-tic resonance apparatus the detection device is provided with one or more surface coils (13) as measurement coils. To avoid mutual inter-ference between a radio-frequency excitation coil (10) and a measurement coil, a measurement coil is provided with a decoupling circuit (36) with which the tuned circuit of which the coil (13) forms  part is tuned to a significantly higher natural frequency during activation of the excitation coil (10). On the other hand the excitation coil (10) is shorted during detection with the surface coil (13) by a low-ohmic shorting circuit (72), thereby avoiding interference with the radio-frequency measurement signals.

Abstract: VEHICLE WINDSHIELD CLEANER CONTROL     Abstract of the Disclosure A windshield cleaner control for a vehicle in which signals from separate washer and wiper actuating switches in the vehicle passenger compartment are voltage multiplexed on a single electric conductor through the firewall to washer and wiper actuating circuitry in the vehicle passenger compartment.  A wiper actuating path is established including, in series, a source of electric power, a wiper motor actuating coil relay, the park switch and the washer motor, the internal impedance of the actuating coil being sufficiently greater than that of the washer motor that the latter is not activated by current flow through the former.  The parallel wiper and washer switches are connected in series between the source of electric power and the electric conductor, park switch and washer motor, but a resistor in series with the wiper switch similarly prevents activation of the washer motor by the wiper switch. Circuit apparatus is responsive to either switch to establish an initial current through the actuating coil, with the park switch closing to complete the wipe cycle.  A timer may be actuated along with the washer motor to activate the wiper motor for extra cycles of extra cleaning after deactivation of the washer motor.

Abstract: Abstract:            For cleaning and/or drying the inner walls of projected pipelines the pressure in the interior of the pipeline is decreased and the vapour formed by evaporation of the substance adhering to the pipe inner wall and, if applicable, present foreign gases are exhausted from the pipeline. Upon exit from the pipeline and prior to entry into the exhausting apparatus, the exhausted medium passes through a condensating apparatus whose cooling surfaces are maintained at a temperature that is lower than the pipe wall temperature. With a temperature difference sufficient to condense the substance vapour on said cooling surfaces it was possible to considerably enhance the drying rate as compared to pure vacuum-type drying.

Abstract: HIGH FREQUENCY GAS DISCHARGE LAMP DIMMING BALLAST            ABSTRACT OF THE DISCLOSURE         A high frequency gas discharge lamp dimming bal-last with good line power factor is disclosed.  The unit is controlled by a current sensing loop which senses control switch current rather than lamp current and employs simple circuitry with sufficiently rapid control response neces-sary to maintain high line power factor and stable lamp operating characteristics over a very wide range of light output.  An isolated output transformer provides protection against most common miswire conditions and accurately regu-lates lamp energy over a wide range of input and lamp arc voltage conditions.  A pulse width modulated control input provides an isolated control input for easier wiring and reduces the susceptibility of the control to noise inter-ference.

Abstract: ABSTRACT          A device and method for converting an X-ray image into a corresponding output image with light from a different source and a phosphorescent layer in conjunction with a liquid crystal light valve.  The light valve includes a photosensor layer comprised of a deposited semiconductor material having distinct light and dark photoconductivities, the light photoconductivity being substantially greater than the dark photoconductivity.      When impinged upon by an particular pattern of X rays, the phosphorescent layer phosphoresces in a corresponding pattern, which phosphorescence in turn causes the semiconductor layer to be switched to its light photoconductivity in a pattern also corresponding to that of the input X-ray image.  The pattern of switched semiconductor in the photosensor layer allows a biasing voltage to be switched over to the liquid crystal layer of the light valve in a corresponding pattern.  This voltage pushes the liquid crystal over its electro-optic threshold thereby inducing an output image corresponding to the original input image.
