Abstract: REVISED TEXT FOR FOREIGN FILING Strachan  HF-0003 U.S.S.N.:  503,500 Filed:  September 5, 1974 Title:  Product and Process Abstract A composite yarn, which is bulky when relaxed and elongates to at least 100 percent greater length under tension, with quick recovery of the relaxed condition when tension is removed, is composed of uncrimped elastic yarn and at least five relatively inelastic continuous fila-ments entangled about the elastic yarn to provide protec-tion and desirable textile properties.  The composite yarn can be made at unusually high speeds by entangling the relatively inelastic filaments about stretched elastic yarn with jets of high velocity fluid impinged at an angle of 90° ? 45° to the yarn axis, using a filament feed rate which provides substantially no net underfeed or overfeed and which, hence, avoids formation of filament loops in the stretched yarn.

Abstract: WIRE INSERTION APPARATUS     Abstract of the Disclosure A tool having a ram with an advantageously formed insertion end portion is employed to force a wire laterally into a terminal of a connector. The wire is properly posi-tioned with respect to the ram by means of guides included in the tool. The tool, with the wire, is properly positioned with respect to the terminal by cooperation with the connector and by a jig with means to hold the connector and ensure proper positioning of the ram end relative to the terminal.          The wire is trimmed as it is moved into the terminal. During the insertion operation the wire is gripped by the tool to prevent axial movement of the wire relative to the tool and terminal.

Abstract: Abstract of the Disclosure A low pressure discharge lamp, particularly a fluor-escent lamp, having a plurality of separate and continuous grooves along its length each of which is formed for 360° around the envelope.  The groove configuration maintains a qen-erally arcuate cross-section of varying radius to thereby alter the wall recombination rate of the plasma ions with the phosphor. In the embodiments where the cross-section of the envelope as deformed by the groove is non-circular, the invention also acts to increase the plasma arc stream length thereby changing the electrical and luminous properties of the lamp.  A method for making the grooves using a plurality of heat sources is also described in which the envelope is rotated and the heat sources are moved toward the envelope as it rotates, each source produc-ing a groove, it also being possible to move the heat sources longitudinally relative to the envelope so that the grooves are angled and/or that groups of grooves are formed in sequence.

Abstract: ABSTRACT                  The invention relates to a clock pulse generator for high frequencies, for example, up to approxi-mately 20 MHz, of a very simple construction. The circuit comprises, for example, an oscillating quartz crystal which is included in a loop together with a capacitor and a single, non-inverting gate. A further, averaging feedback is obtained by means of an inverting gate and an integrating circuit which are connected in series between the output of the non-inverting gate and the input of this gate which is connected to the crystal. The gates may all be Schottky TTL gates. A self triggered clock pulse generator is thus realized.

Abstract: ABSTRACT    A control system is presented for controlling the operation of a borehole sensor.  The borehole sensor includes a three axis gimbal device for determining (1) a vertical plane, (2) a horizontal plane, and (3) the north direction.  Upon receipt of an initiation signal, the control causes a motor drive associated with each gimbal to drive error transducers on each gimbal to desired "home" positions about the three axes and error transducers determine the deviation from desired positions about the axes and provide feedback to the motor drive system to eliminate error.  A "home" signal is generated when each error transducer reaches its "home" position.  When "home" signals are received from all error transducers, the control system then senses the sign and magnitude of the error output from each error transducer and operates the motor drive system to drive the gimbals in directions to reduce the error.  When each error transducer reaches its null position, the control terminates operation of its associated motor drive.  The amount of movement of the motor drive required to drive the error transducer to its null position is measured to determine the deviation between the home position and the null position of the transducer.  When all transducers have reached their null position the control operates to transmit the error measurements for recording or use.

Abstract: SLIDING ????? ??? RESISTANCE WELDING             ABSTRACT OF THE DISCLOSURE           A base is mounted on a welding machine and has slide rails. Each rail has paired flag top sides angulary converging upwardly toward one another.  A table has slide channels also each having paired flat sides angulary converging upwardly toward one another at angles substantially equal to that of the rails. The table channels rest on the rails with their flat sides in sliding relationship to the flat sides of the rails.  When welding forces are applied to the table, the flat sides of the rails and channels jam or wedge into substantially solid electrical contact at their interface due to their angulation. A shield is attached to the end of the table and covers the rails in their exposed projection beyond the table.  In a table having two welding locations, a shield is attached at both ends of the table.  The shields protect the rails against welding sparter, dust, etc., to keep the rails clean to insure maximum electrical contact.  The sliding table allows a workman to load and unload workpieces outside of the welding area which substantially reduces the likelihood of accidental injury.

Abstract: MIXER-DIFFUSOR DEVICE     ABSTRACT OF THE DISCLOSURE     A mixer-diffusor device is attached to the end of a hollow conduit from which a gaseous medium such as steam is to be expelled under pressure.  The end of the hollow conduit is submerged under the surface of a body of liquid such as water.          The mixer-diffusor comprises a conical baffle having an apex extending into the open end of the conduit.  A skirt member is positioned around the end of the conduit so that an annular opening is formed between the wall of the conduit and one edge of the skirt member.  The skirt member is tapered outwardly at essentially the same angle as the taper of the conical baffle.          When the gaseous medium is expelled from the end of the conduit, the gaseous medium flows against and over the conical baffle thereby reducing the thrust forces of the conduit  As the gaseous medium passes the edge of the end of the conduit, the gaseous medium tends to suck the liquid through the annular opening.  The liquid is then mixed with the gaseous medium causing the gaseous medium to form a plurality of small bubbles which are expelled from the opening between the skirt and the conical member.  In this manner, the gaseous medium is sub-stantially mixed and diffused with the liquid.
