Abstract: ACCUPUNCTURE NEEDLE GUIDE AND RESTRAINT      Abstract of Disclosure A locating device for transmitting a mild electrical direct current or pulsating direct current through the body of a patient to locate through increased resistance, as indicated on the meter, areas in the body that may benefit from the application of an acupuncture needle. The locating device has an elongated handle with the necess-ary electrical connection. At one end portion of the handle a trans-versely formed hole receives an elongated, tubular, electrically conductive needle support and guide. Acupuncture needles are very thin and flexible, and require support to obtain best usage thereof.    A restraint, formed of a resiliently yieldable strip of metal or wire extends across one end of the tubular guide and is disposed thereon to frictionally engage a needle to resist travel of the needle down-wardly through the tubular guide. Acupuncture needles are formed with a head substantially thicker than the needle itself, and the afore-said restraint is sufficiently yieldable to afford passage of the head past the wire and downwardly into the tube where desired. A spring is provided to yieldably retain the tubular guide in a predetermined position relative to the longitudinal axis of the handle, and further means is provided to apply a more positive resistance to dislodgement of the tubular guide from a predetermined position.

Abstract: AUTOMOTIVE GAS TURBINE CONTROL            Abstract of the Disclosure A gas turbine power plant, particularly adapted for powering motor vehicles.  The engine includes a gas generator made up of a compressor, combustion apparatus, and a turbine driving the compressor.  It also includes a power turbine energized by the flow from the gas generator rotatable independently of the gas generator.  The power turbine is connected through a suitable transmission to the driving wheels of the vehicle and also drives accessory loads such as the engine fuel and oil pumps, an alternator, air conditioning, a power steering pump, and the like in the vehicle.  The gas generator is substantially free of any accessory drive load, which improves the acceleration characteristics of the engine.         The engine fuel control includes an underspeed governor which responds to power turbine speed and increases fuel flow as required to maintain power turbine speed at a minimum value high enough to power the accessory devices satisfactorily.  A vehicle operator's engine speed request from an accelerator pedal is added to the underspeed governor output signal for operation above idle.  The fuel flow to the engine is limited by a function of engine inlet air tempe-rature and power turbine speed to limit power turbine torque so as not to overload the transmission.

Abstract: ABSTRACT An apparatus and method for forming foundry cores and molds of superior hardness and uniformity in a wide range of sizes includes staging hoppers for storing a first mass of sand coated with a catalyst-polymerizable resin film, and a second mass of sand coated with a catalyst film for polymeriz-ing the resin.  In forming the cores or molds these masses are simultaneously and evenly dispersed into a high velocity car-rier air-sand stream and directed through a static mixer, wherein the resin and catalyst-coated sand particles are inter-mingled and at least a partial integration of the films takes place, into a shaping mold cavity, wherein the sand mixture hardens into a desired shape.  Because the process is fast and continuous, and allows the use of resin-catalyst systems having very fast hardening times, the apparatus and method are par-ticularly well suited to high volume foundry operations wherein it is desirable to reduce the residence time required in the shaping molds to minimize the number of molds and the storage space required.

Abstract: ABSTRACT      Radiation curable coatings, and prepolymers for realizing the coatings.  The coatings are useful for providing films, inks, and varnishes and can be applied to substrates where resistance to abrasion and solvents is desired. The coatings can also be adapted to provide desired release characteristics.    The prepolymers illustratively are liquid reaction products of  polyamine containing polyamids with unsaturated polybasic carboxylic acids, esters, or anhydrides and the reaction products of polyether alcohols with isocyanates, as modified by unsaturated monomers.  The polymerizable liquid preferably includes acrylate monomers with or without unsaturated and copolymerizable pre-polymers.    In order to provide a radiation curable coating with desired release characteristics, various forms of waxy material are included.  The wax has limited compatability with the prepolymers, and a thin layer migrates to a surface to provide, after cure, the desired release property.  The thin surface layer also tends to exclude oxygen and permit curing in air.  The coatings can include a dispersed polymer for shrink control and reinforcement.

Abstract: IMPROVED METHOD OF MULTI-LAYER COATING            Abstract of the Disclosure The simultaneous high speed application of a plur-ality of liquid coating compositions to a moving web by the method, of multi-layer bead coating is improved by coating the lowermost layer as a thin layer formed from a low viscosity coating composition and coating the layer immediately above the lowermost layer as a thicker layer of higher viscosity such that vertical  action of the coating bead is confined to the lowermost layer and the layer immediately above it.          By this means, intermixing of the coating composition forming the lowermost layer with the coating composition forming the layer immediately above it occurs, but all other layers are coated in discrete form.  The method is especially useful in the manufacture of multi-layer photographic films and papers.

Abstract: Abstract of the Disclosure.  A self-contained, battery powered well logging instrument is pumped down the interior of a drill pipe string having a catcher subs at its lower end.  When the logging instrument latches into the catcher sub, the pumped fluid circulation is blocked, after which increased pump pres-sure switches a valve assembly to recreate circulation and energize the logging instrument to the standby position.  An accelerometer in the logging instrument detects the upward move-ment of the instrument and switches the circuitry from standby to the record mode.  The output from a clock controlled by the downhole accelerometer is recorded along with logging infor-mation and is synchronized with pipe footage measurements and with a similar such accelerometer and clock at the earth's sur-face which are responsive to the movement of the pipe string at the earth's surface.  The recorded logging samples are thus related to true depth by correlating with the data simultaneous-ly recorded at the earth's surface.  As an alternative embodi-ment, logging instrument is attached to the drill pipe prior to running the pipe into the borehole.  As an additional embodi-ment, a logging instrument is provided having a variable output accelerometer and associated circuitry which provides depth information independently of the equipment at the earth's surface.
