Abstract: A recirculation device for recirculating a selected volume of preheated gas exhausted from a heating chamber in a mixture with fresh air back to the heating chamber. The device comprises a first passageway having an entrance and a pair of exits; a second passageway having a pair of inlets and an outlet; and a third passageway connecting one exit and one inlet. The other exit communicates with a preheated gas exhaust, and the other intake communicates with a source of fresh air. A back pressure damper is secured adjacent the other exit. A manual control assembly is connected to the back pressure damper so that the volume of preheated gas flowing into the preheated gas exhaust may be selectively determined. A mixing damper is secured adjacent the other intake. An automatic temperature dependent control assembly is connected to the mixing damper so that the mixture of preheated gas and fresh air entering the heating chamber is dependent upon the temperature in the heating chamber.

Abstract: An intrinsic barrier made up of active and passive electrical components which combine to maintain the power in the output lines below a predetermined level in order to prevent the possibility of explosion if the output lines or any circuit electrically connected therewith comes in contact with a potentially explosive atmosphere. Specifically, the intrinsic barrier includes a transistor and a first zener diode combination which serve as a source of controlled voltage to the output lines of the barrier and which combination is protected on the input end by a fuse and also protected on the output end of the barrier by two zener diodes having voltage ratings equal to or greater than the first zener diode mentioned and also having, under prescribed test conditions, destruction times which are significantly greater than the blow time of the fuse and which output line further contains a resistor which has been selected such that the energy level is maintained at a safe level.

Abstract: A modified polyamide-imide resin and method for making the same. The composition comprises the reaction product of an aromatic tricarboxylic acid anhydride reactant, an aromatic diisocyanate reactant and an aliphatic dicarboxylic acid reactant in a solution comprising an aprotic solvent at a temperature ranging from about 70.degree. C. to about 155.degree. C. The tricarboxylic acid anhydride reactant is present in an amount which is greater than about 25 mol percent of the total of the tricarboxylic acid anhydride-aliphatic dicarboxylic acid reactants.The method comprises the steps of dissolving the aromatic tricarboxylic acid anhydride and aliphatic dicarboxylic acid reactants and an excess of the aromatic diisocyanate reactants in aprotic solvent thereby forming a reaction solution. The aromatic tricarboxylic acid anhydride is present in an amount which is greater than about 25 mol percent of the total of the tricarboxylic acid anhydride-aliphatic dicarboxylic acid reactants.

Abstract: A novel magnet wire or other coated filament comprising an elongated filament with a surprisingly concentric and continuous coating superimposed thereupon. The coating may be applied to the desired thickness in a single pass.

Abstract: A novel method and apparatus for manufacturing magnet wire in a continuous process by which coatings of a flowable resin material may be applied concentrically to a moving elongated filament in thicknesses of about 16 mils or less. The filament can be a bare copper or aluminum conductor having round or rectangular configuration or an insulated conductor upon which a top or an intermediate coat of material is desirably applied. Coatings of one and two mils also can be applied by the method of the invention. By the method and apparatus of the invention, magnet wire can be manufactured by continuously drawing the wire to size, annealing the wire, if necessary, insulating the wire with one or more coats of flowable resin material, curing the resin material, if necessary, hardening the resin material, and spooling the wire for shipment, without interruption at speeds limited only by the filament pay-off and take-up devices used.

The filament can be a bare copper or aluminum conductor having round or rectangular configuration or an insulated conductor upon which a top or an intermediate coat of material is desirably applied. Coatings of one-half and one mil also can be applied by the method of the invention. By the method of the invention, magnet wire can be manufactured by continuously drawing the wire to size, annealing the wire, if necessary, insulating the wire with one or more coats of flowable resin material, curing the resin material, and spooling the wire for shipment, without interruption at speeds limited only by the filament pay-off and take-up devices used. The invention utilizes the flowable resin material to center the filament in a die, the size of the die controls the thickness of the coat to be applied.

Abstract: An identification badge for detachable attachment to a wearer comprising a generally planar member having opposite surfaces. One of these surfaces faces outwardly from the wearer. A means is secured to the member for detachably attaching the badge to the wearer. A transparent pocket is formed in the outwardly facing surface. An identification member is removably positionable within the pocket so as to indicate the identity of the wearer.

Abstract: An apparatus for crushing and removing rims from wheels. The apparatus comprises a generally horizontally disposed bed plate for placement within a scrap metal compactor having two oppositely disposed and hinged crushing pads, a carriage having a crushing surface securely mounted upon the bed plate for supporting a wheel comprised of a tire and rim, a wheel receptacle and wheel supports securely fixed on the carriage, two crushing pad points securely mounted on the crushing pads of the metal compactor, and means for moving the crushing pad points downward and into the wheel and rim thereby crushing the rim between the crushing pad points and the crushing surface and facilitating the removal of said rim from said wheel.

Abstract: A heat recycling apparatus operatively connected to a hot air chamber having an exhaust pipe and an intake. The apparatus includes an intake conduit having one end in which there is an opening. A peripheral edge surrounds the opening. The exhaust pipe has an aperture therein through which the one end of the intake conduit extends into the exhaust pipe. The peripheral edge is generally perpendicularly disposed with respect to the longitudinal axis of the exhaust pipe. The opening has an area of between approximately 30% and approximately 65% of the area of the exhaust pipe. A portion of the peripheral edge is contiguous with the wall of the exhaust pipe. The other end of the intake conduit is connected to the hot air chamber.
