Abstract: Abstract An ethylene-acrylic acid copolymer can be used as a flux or a solder-through conformal coating.  The copoly-mer can be melted and used as a coating or core for solder, or applied directly to a component, or made into a thixotropic gel with mineral spirits and/or alcohol, then applied as a coating to a component or assembly. Terpenes may be added as tackifiers in some applications. Whether used as a flux or simply solder-through coating, the material provides a self-healing moisture barrier which can safely remain on the component.

Abstract: Abstract:   The present invention provides non-woven reinforce-ments for resinous composites.  The reinforcements are constructed with warps consisting of non-twist yarns or soft twist yarns of multi-filaments having a high strength and a high modulus, on one or both sides of wefts of non-twist yarns or soft twist yarns containing an adhesive agent.  The warps and the wefts are bonded together at their intersections.  As the reinforcement of the present invention has no flexure, the physical properties of the fibers such as high strength, high modulus and the like, is reflected in the composites using the reinforcement.          In the reinforcement, the warp is not substantially restrained, so that a matrix resin can be impregnated sufficiently into the reinforcement.  Further, the reinforcement can be easily handled, because its shape is maintained by adhesion, and it does not become loose when cut.

Abstract: ABSTRACT OF THE DISCLOSURE     A heating system of the heat pump type is disclosed in which the outside coil, employed to reject heat in air conditioning mode or to absorb heat in heating mode, is supplied with heat independently of that provided by ambient air when the efficiency of the system falls off due to low ambient air temperature.  The amount  of heat thus supplied is controlled to increase the efficiency of the system sufficiently to produce a significant net decrease in operating cost. In a conventional system, the outside air coil-cooling face is turned off and augmenting heat is supplied to the coil when the ambient air tempera-ture is moderate (e.g., 32-38°F) for the system, and the augmenting heat is supplied at a rate which is at least sufficient to restore the efficiency of the system to that inherent with a much higher ambient air temperature.          At the same time, the outside coil temperature is monitored and the augmenting heat is temporarily discontinued when the coil temperature reaches a selected value (e.g., 70°F).

Abstract: QUICK RELEASE AND POSITIVE LOCKING MECHANISM FOR SOCKET WRENCHES AND EXTENSION BARS FOR SOCKET WRENCHES                         ABSTRACT      A quick-release and positive locking mechanism adapted for use on tools for receiving removable sockets, and particularly adapted for use on extension bars of the type frequently employed with socket wrenches.  One form the mechanism comprises a drive stud having a diago-nally disposed bore or opening extending therethrough and having a movable member mounted in said bore with its lower end adapted to extend beyond the contour of the bar and into a recess in the socket or like attach-ment to hold the same when in one position and to be withdrawn from said recess to release the socket or like attachment in another position and with its upper end extending beyond the contour of the drive stud above said socket or like attachment for access for manual movement.  The angle of the bore or opening and the construction of the pin is such that force exerted to remove an attached socket or other attachment cannot generate a component of force on said movable member in the direction of its possible movement such as would cause an accidental or unintended release of said socket.

Abstract: ABSTRACT      New solvent compositions and a new two-stage direct coal liquefaction process are provided which permit control of the liquid product slate from one consisting primarily of low boiling distillate to one consisting primarily of high boiling fuel oil. The use of  the new solving composition  in the process significantly increases distillable liquid yields from coal or lignites.  The preferred solvent contains from about 0 to 100 weight percent of pyridine-soluble bottoms,  i.e.,  mineral matter-free normally solid dissolved coal,  in which the hydrogen content is maintained at an optimum level by adding from about 0.05 to about 2.0 weight percent hydrogen in a hydrotreating step and from about 0 to 100 weight percent of a coal-derived distillate boiling below about 800°F to about 1000°F.

Abstract: AUDITORY SUBLIMINAL MESSAGE SYSTEM AND METHOD               Abstract of the Disclosure Ambient  audio  signals  from  the  customer shopping area within a store are sensed and fed to a signal processing circuit that produces a control signal which varies with variations in the ampli-tude of the sensed audio signals.  A control cir-cuit adjusts the amplitude of an auditory sublimi-nal  anti-shoplifting  message  to  increase  with increasing amplitudes of sensed audio signals and decrease with decreasing amplitudes of sensed audio signals.    This  amplitude  controlled  subliminal message  may  be  mixed  with  background  music  and transmitted to the shopping area.   To reduce dis-tortion of the subliminal message, its amplitude is controlled to increase at a first rate slower than the  rate of increase of the amplitude of ambient audio signals from the area. Also, the amplitude of the subliminal message is controlled to decrease at a  second  rate  faster  than  the  first  rate  with decreasing ambient audio signal amplitudes to mini-mize  the  possibility  of  the  subliminal message becoming   supraliminal  upon  rapid  declines  in ambient  audio signal  amplitudes  in  the  area.   A masking signal is provided with an amplitude which is also controlled in response to the amplitude of sensed ambient audio signals.  This masking signal may  be  combined  with  the  auditory  subliminal message to provide a composite signal fed to, and controlled by, the control circuit.
