  • Patent number: 5266743
    Abstract: Sealing member for an electric cable having an outer relief surface formed by an array of electrical conductors in a spaced apart relationship concentrically laid over an insulating sheath of the electric cable. The sealing member comprises a collar of flexible and resilient material including a plurality of elongated cavities spaced apart by a distance corresponding substantially to a spacing between electrical conductors of the array, and an outer sealing surface of a generally cylindrical configuration. The collar engages the electric cable concentrically, whereby electrical conductors of the array are caused to enter into respective cavities of the collar which is capable of forming a non-leaking union between the electric cable and an adjacent body in a mating relationship with the collar. The invention also extends to a sealing assembly to form a fluid-tight seal between the electric cable and a surrounding enclosure.

  • Patent number: 4953682
    Abstract: An apparatus crushes aluminum cans at a fast rate and dispenses compensation for the crushed cans. The apparatus crushes the cans on the longitudinal axis rather than lengthwise which results in a more compact unit thus saving storage space. The apparatus also processes the cans faster than most existing machines. The apparatus comprises an enclosure with an opening for receiving cans leading to a chute for the cans to fall one at a time with the cylindrical axis substantially vertical. A dispenser releases one can at a time from the chute past a detector to reject any cans that are not aluminum, through a gate which closes and permits a platen to crush the can on the closed gate. The crushed can is ejected into a discharge container and compensation commensurate with the number of cans processed is issued.
