摘要： The process for producing a shaped article comprising a polythene terephthalate (PETP) core containing from 0 to 50% of mineral fillers and a covering layer of a second thermoplastics material having a softening point below that of the PETP. The second material and the PETP are injected one after the other into a mould which is maintained at a temperature below the crystallization point of the PETP having regard to its fillers. The second material injected in the first phase acts as a thermal buffer slowing down temperature equalization between the PETP injected in the second injection phase and the mould, thus ensuring the required properties in the PETP core.

摘要： An apparatus and a method of use thereof for cast encapsulation of items, particularly electronic components. The apparatus consists of a plurality of identically shaped split matrix elements. Each matrix element has a first surface for receiving and securing the item to be encapsulated. A second surface of another identically shaped matrix element, located on a side thereof opposite to its first surface, is then mated with the first surface securing the item. Thus mated, the first and second surfaces establish a molding cavity for enclosing the item and an orifice providing access thereto. This process of securing an item to a first surface and enclosing it with a second surface is repeated thereby assembling a stack of matrix elements. This stack is then rigidly secured and the molding cavities are filled with particulate filler material through upright orifices. Excess filler is removed by quickly turning the stack over and then righting it again. The stack of matrices is then heated, its orifices filled with a quantity of heated, liquid thermosetting encapsulating compound and exposed to vacuum whereby substantially all air is drawn from the molding cavities through the liquid encapsulating compound. The stack is then again exposed to atmospheric pressure forcing the encapsulating compound throughout the unoccupied voids in the molding cavities after which that compound is permitted to solidify, thereby completing the encapsulation process.

摘要： The invention relates to a method and apparatus for producing an insulated joint between electrical conductors, particularly between cables insulated by cross-linked polyethylene material. Heat is applied to joined parts of the conductors which have been covered by a cross-linked polyethylene material in uncured condition and closely confined within an enclosure which is heated until the said material is cured, pressure being applied to the joint while the joint is cooling, whereby voids in the cured joint are substantially suppressed. More specifically, parts of cable cores are connected together, the joint and adjacent portions of the cables are covered with the uncured material, the covered joint is heated within a mould until the material is cured, and pressure is applied to the joint while it is cooling. Advantageously, the uncured material is in the form of a tape.The mould cavity for the joint may be defined by two mould parts and the pressure applied by moving one of them in relation to the other. Alternatively the pressure may be applied by pistons slidable in cylinders communicating with the cavity. In either case the pressure may be applied through spring means.

摘要： A high production isostatic molding device comprising an upright, yoke type isostatic press and a turntable for rotating a plurality of elastomeric molds, hung beneath the table, sequentially through various processing stages including filling, pressing, and unloading. At one position a given mold is filled with compactible material from a hopper while being simultaneously vibrated. At another position the mold is positioned over a pressure vessel cylinder which is lifted up around the mold to engage a pressure end-block thereby forming a sealed pressure vessel. At still another stage the compacted material is lifted free of the mold and placed on a conveyor belt by a hydraulicly operated arm having a vacuum pad at its end and mounted on a wheeled carriage over the turntable.

摘要： A method for preparing solid metallurgical mounts uses a surface in heat exchange relationship with mounting molds placed thereon and with an initially liquid mounting agent contained in the molds. The surface is defined by a block of polytetrafluoroethylene exposed to a source of heat. As part of the molding operation, the surface is preheated and maintained at a substantially constant temperature throughout the operation. The molding operation includes mixing of a quantity of epoxy resin and a hardener, pouring the mixture into a mold or molds and curing the mixture at an elevated temperature in contact with the polytetrafluoroethylene surface.
