Abstract: The present disclosure illustrates a fastener with an arrangement on the head of the fastener for receiving a medallion, coin or other flat commemorative or decorative item. A threaded stud is secured to a cap which includes a receptacle on a rear surface, complimentary to the head of the stud, and a display pocket on a forward or outer surface for receiving the medallion or coin. The receptacle on the rear side of the cap includes an upstanding rim or lip having an inside diameter slightly larger than the outside diameter of the head of the stud. In the disclosed embodiments, the cap is secured to the stud by swaging or deforming the rim against the head of the stud to rigidly and permanently attach the cap to the stud, forming a fastener with an enlarged head.

Abstract: A spool valve and valve seat assembly disposed in the control module of a hot melt adhesive dispensing system is uniquely structured so as to effectively prevent fluid communication or “cross-talk” between a first dispensing outlet port and a second recirculation port, during those periods when the control module is effectively reciprocally cycling the spool valve between its oppositely disposed extreme conditions for alternatively permitting the hot melt adhesive material to be dispensed from the first outlet port or for re-routing the hot melt adhesive material through the recirculation passage so as to prevent the hot melt adhesive from being improperly dispensed as a result of being undesirably routed to the recirculation passage.

Abstract: A new and improved hot melt adhesive hose assembly comprises a hot melt adhesive hose core, a pair of heater circuits wrapped around the external peripheral surface of the hose core, and a pair of temperature sensors also disposed in contact with the external peripheral surface of the hose core. A first one of the heater circuits is initially electrically connected to the hot melt adhesive hose assembly electrical circuitry, and in a similar manner, a first one of the temperature sensors is electrically connected to the hot melt adhesive hose assembly electrical circuitry.

Abstract: A hot melt adhesive hose assembly has a redundant control circuit fixedly mounted thereon which comprises a pair of heater circuits for heating a hot melt adhesive hose assembly to a predetermined temperature level, and a pair of temperature sensors which are used to sense the temperature of the hot melt adhesive hose assembly wherein the sensed temperature level will be used to control energization of the heater circuits in order to maintain the desired temperature level. A first one of the heater circuits is initially electrically connected to the hot melt adhesive hose assembly electrical circuitry, and in a similar manner, a first one of the temperature sensors is likewise electrically connected to the hot melt adhesive hose assembly electrical circuitry.

Abstract: A biofidelic lower leg surrogate includes a latex skin containing tissue simulating gelatin and a simulative bone assembly. The bone assembly is defined by a hollow, cylindrical, polymeric tibia body connected to an ankle piece in the shape of a section of a solid cylinder; a pair of heel blocks bonded to each other and to the ankle piece with a triangular bottom opening therebetween defining an arch; a nylon tendon strip mounted in grooves in the bottom of the heel blocks; and a heel pad extending across the bottom of the blocks.
