Abstract: A viscous sealing material is applied to a communications cable by being forced out of a container by means of a heatable pressure plate having a bore and a pump adjacent to the bore; the sealing material is conveyed by the pump through a conduit to a chamber, in which the sealing material is introduced under pressure into and around an already stranded cable core; the pressure plate includes a plurality of preferably helically coil electrical heating elements separated from each other and projecting therefrom for penetrating into the sealing material in the container when the pressure plate applies pressure to the sealing material so that it is progressively liquified and can be pumped out of the container.

Abstract: In accordance with the teachings of the instant invention, there is disclosed an injection molding head for forming honeycombed structures of thermoplastic materials, which comprises a fixed mouthpiece having a plurality of strand channels extending longitudinally therethrough; a plurality of guide channels extending longitudinally therethrough and interposed between said strand channels; a strand deviation guide mechanism comprising a plurality of elongated members each slidably mounted in one of said guide channels; a frame arrangement attached to one end of each of a group of the elongated members for moving in a longitudinal direction one end of each of the elongated members beyond the exit end of the fixed mouthpiece for the provision of high thrust, lateral forces proximate to the output of said strand channels, and withdrawing the ends of the said elongated members from said extended position to within said fixed mouthpiece; and a drive apparatus coupled to the frame arrangement for moving the frame ar
