Abstract: ABSTRACT OF THE DISCLOSURE:           A thread form for a tubular connection has a pin member adapted to be made up with a box member to form a pipe joint.  The pin member has pin threads with thread crests and thread roots which are adapted to be made up with a mating box member having a complementary thread structure. The pin thread crests are formed between a stab flank and a load flank of the pin thread.  The pin thread has a chevron-shaped load flank for engaging a mating chevron-shaped load flank of the complimentary box member to provide a chevron type interfit between the load bearing flanks.  The load flanks of the pin member includes an outer wall portion with a positive slope which provides additional clearance between the complementary threads on the pin and box members during disassembly  to prevent  inadvertent  hanging-up of  the threads.

This device comprises a cylindrical tube transversely secured to the main body of the bow, and a piston rod reciprocately engaging the tube according to the motion imparted thereto by the user.  The inner end of the piston rod is abuttingly engageable by the bow-tensioning cord and is capable of stretching the latter outwardly form the bow main body.  The piston rod is used as an arrow, except that it remains mounted in the cylindrical tube, never leaving the bow after release of the stretched tensioned bow cord.

Abstract: Abstract:    Low quality, low density woods are densified to form wood products having the characteristics of high quality natural hardwoods.  A green solid wood member having a high moisture content is impregnated with anhydrous ammonia to plasticize the wood into a sponge-like form saturated with water and ammonia.  This plasticized wood member is placed between press plates of a cyclic press and, while maintaining the temperature of the wood below 100°C, it is subjected to a plurality of low pressure compression cycles each of about 1/2 to 1 minute duration with the wood being compressed to a predetermined thick-ness of up to 50% less than its original thickness.  It is held at the reduced thickness for a short time and released during each cycle, whereby water and ammonia are squeezed out of the wood down to a moisture content of less than about 30%.  The damp wood member of reduced thickness thus obtained is then dried to obtain a kiln dried, densified solid wood product.  This method may be used to densify wood planks, pre-glued laminates and thin veneers.  For veneers, a simpler pressing system and higher temperatures may be used.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention discloses human headache relief by application of electrical pulses of an approximate frequency of 10-12 pulses per second to a headache sufferer's skin. Ideally, the pulses are of an amplitude just below the sufferer's pain tolerance level (typically 60 to 150 volts) and are applied by two electrodes:  a ground electrode makes contact with any skin area away from the neck or head and a live electrode makes contact with the sufferer's neck or head, depending on the type headache suffered.          Further, the pulses preferably have a square wave form with the pulse width approximately 40 microseconds. An application for two minutes is normal and usually provides at least 6 hours relief.

Abstract: ABSTRACT        Method and Apparatus for Reducing the Gas Content of a Liquid. In a method of reducing the gas content of a liquid in which the liquid is propelled, preferably in a closed circuit, by a centrifugal pump (1), an improved degasification capability is achieved by extracting a portion of the liquid from the suction side of the pump blades  (5,  18)  in the region of the impeller axis, preferably via a passage (20) extending through a hollow drive shaft (21) of the impeller (14), and conducting this portion of the liquid through a liquid stilling zone (55, 56) where fine gas bubbles are separated from the liquid.   The degassed liquid is preferably returned to the liquid in the inlet pipe (15) upstream of the pump  (1), where it is set in rotation by a helical member (10).   The liquid extracted from the pump (1) may be sucked out by means of an auxiliary rotary pump (3), or it may be entrained by injecting a high speed stream through a venturi nozzle  (39)  housed by the impeller  (14) coaxially with the hollow drive shaft (21).  In this latter case the degassing of the liquid in the stilling zone (55,  56) may be assisted by an atomizer (44).

Abstract: ABSTRACT OF THE INVENTION         The hair trimming apparatus disclosed herein is particularly adapted for trimming beards, mustaches and the like.  It includes a hair clipper and a one-piece adjustable comb attachment.  The comb attachment is slidably secured to the hair clipper by rails or the like which surround part of the clipper, such as the side edges of a stationary blade.          The position of the comb attachment with respect to the blades is determined by placing any one of a plurality of indentations in the attachment over a protruding part of the clipper, such as one or more screw heads which secure one or more of the blades to the clipper.  The position may be easily changed by merely moving the attachment to a different indentation.  In this manner, the comb attachment may be easily secured to the clipper in any one of a number of positions, without manipulating other parts of the apparatus.  In addition, fins on the comb attachment are recessed behind the clipper blades so that the clipper may more easily reach and trim mustache hair by cutting it in the direction of hair growth.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an improved method for forming a grafted rubbery particle suitable for use as a reinforcing rubber in a thermoplastic resin.  The grafted rubbery particles produced by the method of the present invention have a substan-tially continuous, generally uniform layer of polymer grafted to the rubbery particle core.  In contrast to the known methods, this invention involves a sequence of steps that result in poly-merizing the elastomeric core, of generally hydrophobic monomers, in a manner which provides a thin hydrophilic outer layer.  This thin hydrophilic outer layer is sufficient to encourage subsequent substantially continuous generally uniform grafting of rigid phase monomers on to the elastomeric core.

Abstract: PROTECTED INPUT/OUTPUT CIRCUITRY FOR A         PROGRAMMABLE CONTROLLER          Abstract of the Disclosure Input/output circuitry is disclosed for use in an I/O system of a programmable controller.  The circuitry is protected against overcurrents without the use of fuses or circuit breakers, and is automatically restored to normal operation following correction of an overload condition.  Diagnostic signals are produced for monitoring the operating condition of the circuitry.  The invention includes an insulated gate transistor (IGT) having a main current section carrying a majority of the load current and an emulation section which carries a fractional portion of the load current.  The emulation section current tracks the total current at all times.  A current sensor monitors the emulation section current and provides a signal representing the instantaneous load current.  This signal is continuously compared with preselected reference levels to derive a set of diagnostic signals that are indicative of the operating condition of the circuit, and whether output loads are open or shorted, for example.
