摘要： Making a gas pressurizable closure for a splice region of a telecommunications cable in which plastic ends of the closure are molded in position by locating molds for the ends in axially spaced-apart positions one at each side of the splice region. While the cable is allowed to follow its natural path through and between the molds, the molds are held fixed relative to one another and aligned with one another and the plastic ends are molded. A shroud means of the closure is then located between and sealed to the plastic ends with the cable still following its natural path.

摘要： A seal for a cylindrical article and having two sealing members which coact to form the seal. Each sealing member has a resiliently flexible body which is connected to a rigid support at two spaced positions around the body. An intermediate portion of the body is resiliently flexible outwards between the two spaced positions while two body end portions extending beyond the spaced positions are caused to resiliently flex inwards. Alternatively, outward flexing of the end portions is accompanied by inward flexing of the intermediate portion. The change in shape caused by this flexibility enables the seal to be used upon a range of different diameters of articles.

摘要： In a low pressure mold, the mold parts have surfaces for forming a mold cavity and which are covered in a thermally insulating coating with a thickness from 0.005 inches to 0.050 inches. The coating may be formed from epoxy resin or polytetrafluorethylene. Also provided is a sealing member for a low pressure mold, the sealing member having in-series edge regions around a body and each edge region is formed with a semi-circular sealing edge or arrangement of edges. The sealing edge or arrangement of edges of each edge region is different from other edge regions. When the two sealing members are mounted upon mold halves at each end of a low pressure mold, they may be changed in position to locate any associated pair of sealing edges in opposition across the mold closure line.

摘要： A method of forming a molded encapsulation around a sealed spliced region between two cables in which the cables pass through a mold with the splice region in the mold cavity and correctly centered before molding. To allow for the centering operation to be performed, apertures are provided in the mold. Hook members are passed through the apertures. These hook members are caused to engage both inner and outer mold surfaces and they also engage tie means at two circumferentially spaced positions around the splice region to centralize the region within the cavity. The mold is then filled with molten material and the hooks removed from the apertures with the material still molten. Hook removal may take place either when the cavity is completely filled or after sufficient molten material has entered the mold to hold the splice region in fixed position. The method is applicable to low pressure molding, i.e. below 100 psi and preferably below 50 psi.
摘要翻译：在两个电缆之间的密封接合区域周围形成模制封装的方法，其中电缆通过具有模腔中的接合区域并且在模制之前正确居中的模具。为了允许执行定心操作，在模具中提供孔。钩构件穿过孔。引起这些钩构件与内模和外模表面接合，并且它们还在接合区域周围的两个周向间隔位置处接合连接装置，以将腔内的区域集中。然后用熔融材料填充模具，并且使钩子从孔中移除，材料仍然熔化。当空腔完全填充或者在足够的熔融材料进入模具中以将接合区域保持在固定位置之后，可以进行钩除去。该方法适用于低压成型，即低于100psi，优选低于50psi。

摘要： A seal assembly with a split housing provided with two axially spaced recesses for two seals. In each split housing member recess one-half of a seal is held. The two seal halves of each housing member are held in place by an elongate holding member which is secured to the housing member and mechanically holds the seal halves in their respective recesses. Rapid assembly and disassembly of the seal parts is thus possible.
