Abstract: This relates to a heat sealer for engaging heat sealable material between a pair of heat sealer members and clamping the material to be heat sealed under a controlled force. The heat sealing mechanism includes a pair of parallel members which are mounted for movement in unison and in opposite direction and which carry the heat sealing members which face in opposed relation. A pressure device is attached to one of the parallel members for moving the parallel members to a closed heat sealing position and a mechanical mechanism in the form of a cam is connected to the other of the parallel members for overriding the pressure device and effecting opening of the heat sealing members. The pressure device is in the form of a simple fluid cylinder and the fluid supply therefor is of the variable type whereby the controlled force exerted by the heat sealing members on the article to be heat sealed may be selectively varied.

Abstract: A fiber optic cable for use in a fiber optic connector in which a ferrule is compressed around the end of the fiber bundle in the cable. The bore in the ferrule has a cylindrical wall with circumferentially spaced flat surfaces thereon which minimize the compression hoop effects on the peripheral fibers of the bundle, thereby maximizing fiber bundle consolidation.

Abstract: A method and apparatus for terminating a fiber optic bundle in which the bundle is inserted without an adhesive into the rear of a contact. An adhesive is then injected into the fiber bundle from the front of the contact and allowed to dry. The apparatus comprises a body which supports a contact containing a fiber optic bundle and an injector which is loaded with a charge of adhesive and mounted on the body in such a manner that the adhesive is forced into the interstices between the fibers in the bundle.
