摘要： A thermoformed vacuum insulation container is provided for use in a vacuum insulation panel. The container is preformed to have a receptacle area for receiving a quantity of microporous insulation material as well as a peripheral ledge area. The microporous insulating material is isolated by a porous sheet material which is either sealed to the ledge area covering the receptacle area, or completely bounds the microporous insulation material in the form of a pouch or sack. An impermeable layer is sealed to the ledge area following evacuation of the receptacle area and microporous insulation material of gases and moisture in order to complete the evacuated panel.

摘要： A refrigeration appliance having a vacuum insulation system wherein a combination of vacuum thermal insulating panels and polyurethane foam provide the thermal insulating properties as well as structural support. The panels are to be spaced apart from one another with a space between the cabinet and appliance liner so that the foam will lock the panels in place. Also the panels are to be spaced from the corners of the cabinet to permit the foam to flow into the corners. The panels can be applied directly to the cabinet or they can be spaced between the cabinet and liner, held by spacers. In either case, an adhesive is used to hold the liners in position prior to introduction of the foam.

摘要： A method of molding an element from liquid synthetic resin wherein liquid resin is introduced into a mold cavity through a first gate and liquid resin is concurrently introduced into the mold cavity through a second gate with portions of the resin received through each of the gates meeting at a joint interface. The resin in the second gate is caused to solidify sooner than the resin in the first gate so that the leading surface of the resin received through the first gate projects into a leading surface portion of the resin received through the second gate during the mold packing operation to provide an enlarged weld line area and improved strength in the joint. Apparatus for carrying out this method includes structure for causing the temperature in the gate of one of the resin streams to be different from that of the temperature in the gate of the other of the resin streams as a result of preselected characteristics of the respective gates through which the resin streams are passed. In an illustrated embodiment, a first gate passage may have a different cross-sectional configuration than that of a second gate passage so that the resin in the first gate may be cooled or heated to a different degree than the resin in the second gate, through differences in the heat transfer characteristics of the walls defining the respective passages. Alternatively, the first and second gate structure materials may have different thermal diffusivities. Further alternatively, the flow through the first gate may be terminated prior to the termination of flow through the second gate. In an illustrated embodiment, the invention is employed in an injection molding apparatus having more than two gate structures.
