  • Patent number: 5447464
    Abstract: An automated method is disclosed for grinding and polishing the terminated ends of the optical fibers in a fiber optic cable. The abrasive material, in strip form, is moved in a carriage along a linear path while the carriage is oscillated in a circle within a plane during polishing. There are three separate work stations operating concurrently, the first having a relatively course grade of abrasive while the others have finer grades. Fixtures holding the cables for polishing are held in fixture supports that are automatically fed toward the abrasive material during polishing and retracted after polishing is complete. The fixture engagement mechanism for the first carriage engages at a slower rate than do the mechanisms of the other carriages.

  • Patent number: 5427545
    Abstract: An electrical terminal assembly comprising an electrical terminal has an insulation displacement contact having a base portion from which extend a pair of coplanar arms defining a slot for receiving an insulated lead. A restraining flange projecting from the top of each arm at right-angles to its plane terminates in a foot which is received in a well in a housing having a cavity receiving the terminal assembly. The well is dimensioned to allow the foot to move parallel to the plane of the arms but not at the right angles thereto. The arms cannot, therefor, twist about their longitudinal axes under the lead insertion force, but can move in their own planes to accommodate the metal cone of the lead as it is forced into the slot.

  • Patent number: 5384954
    Abstract: A method of manufacturing a guide plate for use in a chip carrier socket or other electrical connector provides the precision required for close-center line spacing while minimizing the cost associated with production. A block of ceramic or the like is ground to the precise outside dimensions required. Grooves are then cut in the block of ceramic, and the ceramic is then sliced into respective guide plates. The guide plates are inserted into openings provided in the electrical connector an retained therein. The grooves are dimensioned to cooperate with contact pins of the electrical connector to precisely maintain the pins in position, whereby when a chip is positioned in the electrical connector, the pins will be in position to make an electrical connection with the pads of the chip.

  • Patent number: 5369482
    Abstract: An apparatus is disclosed for measuring the refractive index of index matching gels. A light source (10) is directed into one (20) of the output legs (20, 22) of an optical splitter (18), where the input leg (26) is interconnected to a fiber optic cable (27). The end of the cable (27)is inserted into the gel (30) to be measured. The incident light source (10) directs an incident light source through the splitter, and through the end (29) of the fiber optic cable (27). The difference in refractive indexes between the fiber optic cable (27) and the gel (30) causes a reflection of the incident light back to the splitter (18) and through a measuring device (52). By measuring the reflected power, and by knowing the incident power and other known factors, the refractive index of the gel can be calculated.
