Abstract: A method of terminating the fiber core of a fiber optic cable relative to the mating end of a fiber optic connector. The connector includes a through hole for receiving the fiber optic cable with a length of the core, stripped of its outer coating, protruding from the through hole at the mating end of the connector. The method includes the steps of clamping the fiber optic cable within the connector against lengthwise movement of the cable, cleaving the length of the core flush with the mating end of the connector, and applying a separation force lengthwise of the core during the cleaving thereof. A flat, smooth end surface results and thereby eliminates subsequent polishing or other preparation of the core end.

Abstract: @ The conventional processing of rubbers into shaped articles of manufacture normally include a compounding step. In this compounding step the rubber is mixed with fillers, curatives, and various other additives so as to obtain a homogeneous mixture.

     The present invention provides an improved process for the production of tack-free, pourable, filler containing powdered rubber. This powdered rubber can be compounded eliminating in whole or in part the need for heavy equipment which consumes high amounts of energy. This invention more specifically reveals that in a process for the production of tack-free, pourable, filler containing elastomer powder which comprises:
