Abstract: Satellite Communications System and Apparatus Abstract A satellite communications system, which is inherently power limited, employing spread spectrum techniques in order to trade-off bandwidth for small ground station antennas.  In a one-way system embodi-ment a central station transmits data to a satellite for relay to a large number of small antenna receiving stations, the transmissions being spread spectrum encoded with spreading code lengths selected to provide adequate data recovery at the least sensitive station to which the transmissions are directed. Spreading codes may also function to address particular stations.  In a two-way system embodiment, the central station additionally functions as a terrestrial relay station.  A plurality of small antenna transmitting stations, at least one of which may be at the same site as a receiving station, transmit code division multi-plexed data via the satellite to the central relay station using sufficiently long and distinct spreading codes as to permit adequate data error rates and to distinguish the transmissions of the various stations. The central relay station reformats the received data for retransmission to the satellite for relay to the receiving stations.

Abstract: ELECTROSTATIC HIGH VOLTAGE DRIVE CIRCUIT USING DIODES      Abstract of the Invention A diode switching system for use with an electrographic writing system is disclosed.  The switching system has a high stor-age charge diode with a capacitor connected to its anode which de-fines an output.  Once the diode is charged, application of a large drive voltage to the free end of the capacitor will short the volt-age through the diode due to the stored charge of the diode, thus preventing the stylus from writing.  When the diode has not been charged, application of a large drive voltage will be coupled through the capacitor thus powering the writing stylus.

Abstract: ABSTRACT OF THE DISCLOSURE A thyristor matrix arrangement having four columns, each column being formed of n thyristors connected in series with each other.  In one embodiment, the series connected thyristors in respective columns are coupled to one another via heat sinks.  The thyristors in each column are poled such that forward conduction current cannot flow through only one of the columns. The heat sinks are cross-connected among the columns to form a current path which is formed of appropriately poled thyristors in different ones of the columns and the column cross-connections.  The cross-connections are inductive so as to provide relatively large inductive voltage drops when the thyristors are fired, thereby enabling the firing of thyristors having relatively low firing and forward voltages.

Abstract: METHOD AND APPARATUS FOR RETHREADING           TUBULAR MEMBERS AND RESULTING PRODUCT                         ABSTRACT       A method and apparatus is disclosed for rethreading damaged or incorrectly threaded tubulor members such as tool joints, casing, and tubing for oil wells, which methods and apparatus are particularly advantageous for use with NC and CNC machines. A standard numerical production program of the machining system is operated to form a standard acceptable thread and sealing surface for a tubular blank member. A threaded adapter is placed on the newly formed threads.          The adapter has an alignment mechanism. A preprogrammed position in the machining system advances the turret toward the adapter to a preprogrammed stopping point. A sliding locator assembly is moved into aligning engagement with the adapter. The locator assembly is locked in the turret while engaged in the adapter. The program in the machine system is then operated to withdraw the turret and locator assembly from the adapter. The standard threaded blank is removed from the collet and a tubular piece to be rethreaded is positioned loosely therein. The adapter is threaded onto the tubular piece. The spindle is aligned radially with a fixed position on the machine. The program system moves the turret to the preprogrammed stopping point. The tubular piece and adapter are moved until the adapter engages the locator assembly and the tubular piece is then locked in the collet.          The turret moves to disengage the locator assembly from the adapter and the adapter is then removed. A rework program in the machine system forms a standard thread and seal surface on the tubular piece a desired distance into the piece further than the production program which distance is some multiple of the width of one standard thread.

Abstract: ABSTRACT OF THE DISCLOSURE          An apparatus for irradiating a continuously flowing stream of fluid is disclosed.  The apparatus consists of a housing having a spherical cavity and a spherical modera-tor containing a radiation source positioned within the spherical cavity.  The spherical moderator is of lesser diameter than the spherical cavity so as to define a spherical annular volume around the moderator.  The hous-ing includes fluid intake and output conduits which open onto the spherical cavity at diametrically opposite posi-tions,  Fluid flows through the cavity around the spheri-cal moderator and is uniformly irradiated due to the 4n radiation geometry.  The irradiation source, for example a 252Cf neutron source, is removable from the spherical moderator through a radial bore which extents outwardly to an opening on the outside of the housing.  The radiation source may be routinely removed without interrupting the flow of fluid or breaching the containment of the fluid.

Abstract: CURRENT TRANSFORMER SECONDARY VOLTAGE LIMITER            ABSTRACT OF THE DISCLOSURE         A device for protecting the secondary winding of a current transformer against destructive or dangerous overvoltages when connected across the secondary, has a transparent tubular casing with a stud support and conductive stud within one end.  The stud is threadably mounted in the stud support so it can be adjusted longitudinally and it has an arcing surface on its inner end.  Within the other end a support member carries a longitudinally sliding conductive plunger.  The plunger is biased inwardly towards the arcing surface of the stud but it is restrained from inward movement by a fusible element which engages it and restrains it.  The fusible element forms another arcing surface spaced a predetermined distance from the arcing surface on the stud.  One terminal is provided on the outer end of the conductive stud and another on the outer end of the support member connected to the plunger by a flexible braid.  A small overvoltage of short duration causes an arc current to flow to limit the voltage.    An overvoltage of longer duration fuses the fusible element allowing the plunger to move inwardly to short the terminals and the secondary windings.  If desired an auxiliary contact arrangement will indicate when the fusible element has fused and the device shorted.

Abstract: PRESSURE REGULATING VALVE                    ABSTRACT OF THE DISCLOSURE          A valve system is disclosed in which sleeves provid-ing an unbalanced area are arranged so that the unbalanced area is exposed to the zone of higher pressure and produces a sealing force between the sealing face of the sleeves and a mating valving surface, which force is a direct function of the difference in the pressure across the seal.  Adapter rings are positioned behind each seal and a spring provides an initial light bias on the sleeve to urge it into mating engagement with the valving surface.  The adapter ring and sleeve structure is arranged so that all of the sleeves, including those sleeves having an external unbalanced area, may be assembled in the valve body from the end of the sleeve receiving passage remote from the valving surface.  The adapter rings also make it possible to use standard length sleeves in combination with relatively low cost adapter rings having lengths selected to provide a total sleeve adapter ring length which matches the length of the passages in the valve body.
