Abstract: An electrically heated nozzle for use in injection molding which is positioned between an injection apparatus and a die casting machine in an injection molding operation. The nozzle transfers molten material such as metal under pressure from the injection apparatus to the die. The nozzle has a refractive core, with a flow passage, surrounded by an intermediate metal core which is heated by a coil of electrical resistance wire to prevent heat loss in the molten metal. A metal sleeve surrounds the coil and the intermediate core. The heating coil is attached to a control box which energizes the coil and controls the temperature.

Abstract: A die casting apparatus for pumping molten metal from a heated container to a nozzle communicating with an inlet of a mold including a charging mechanism for charging the apparatus with a predetermined amount of molten metal from the container and a multi-piece holder removably joined together by fastener means. The holder defines a shot barrel chamber and a gooseneck chamber extending in a curved path from the charging mechanism to the nozzle. A refractory shot barrel is removably positioned in the shot barrel chamber in communication with the molten metal in the heated container, and two refractory insert halves are removably positioned in the gooseneck chamber and coact to define a gooseneck passage at their parting interface providing fluid communication between the outlet of the shot barrel and the inlet of the nozzle.

Abstract: A receptacle adapted to be disposed for receiving, by gravity, waste discharges from a person is an elongated container having an elongated aperture defined at the top thereof for receiving waste into the container. The container has side and end surfaces specially formed with concave surfaces to direct laterally-moving fluid waste in the container, the motion being caused by movement of the receptacle, in a generally upward direction, and the container has a portion for thereafter directing the fluid downward, back on itself to dampen sloshing or wave motion to prevent spillage and splashing. In another aspect, the receptacle is disposed in waste-receiving relationship to a person on a chair for an incontinent disabled person, the chair having an apertured cushion disposed over the receptacle which is mounted to be removed from the chair.
