  • Publication number: 20210317933
    Abstract: A fitting includes a first and second threaded fitting component and a conduit gripping device receivable within the first threaded fitting component. A stroke resisting member is integral with the first threaded fitting component and includes a web having a first radial thickness and extending axially inward from the first threaded fitting component to a distal ring portion having a second radial thickness greater than the first radial thickness. A radially extending bearing surface of the distal ring portion axially engages a radially extending portion of the second fitting component when the first and second fitting components are joined together to the first relative axial position. The stroke resisting member resists additional axial stroke of the first and second fitting components, such that a tightening torque beyond the first relative axial position is increased by the axial engagement.

  • Patent number: 6565394
    Abstract: A jumper cable for use with electrical meter sockets includes an improved clamp at each end. The clamp includes a substantially coaxial threaded rod, threadedly secured to a movable jaw that may move between an open position and a closed position, guided between a pair of guide surfaces that are angled in an orientation that is not parallel to the threaded rod. The movable jaw may therefore be caused to be move laterally by rotating a knob at the end of the threaded rod that is located at the end of the clamp opposite the jaws, where it will provide the best access to itself, and minimize interference with meter removal.

  • Publication number: 20020182930
    Abstract: A jumper cable for use with electrical meter sockets includes an improved clamp at each end. The improved clamp provides more secure clamping to each bypass horn of the supply bus and corresponding tenant bus within the socket, while also preventing interference with installation and removal of an individual meter. By clamping one end of the jumper to a supply bus, clamping the other end of the jumper to the corresponding tenant bus, and connecting a similar jumper cable to each pair of supply buses and corresponding tenant buses within the meter socket, the meter may be removed from the socket without interrupting the flow of electrical currents.

  • Patent number: 6421229
    Abstract: A meter/breaker arrangement having separate covers for the meter side and breaker side. The meter side includes as an extension thereof a rain gutter which underlaps a flange on the breaker cover to provide a rain-proof or water-proof enclosure when both covers are disposed securely on the enclosure. In addition, a locking arrangement is provided so that the breaker cover can be removed without allowing access to the meter region. Alternatively, both the meter cover and breaker cover can be removed. A flexible, partially non-electrically conductive, security member is provided for separating the meter side from the breaker side.

  • Patent number: 5843354
    Abstract: A method for compression molding a resin-impregnated preform to fabricate an impact-resistance, fiber-reinforced composite fan blade for use in a high bypass turbofan engine. The method is compatible with the use of high viscosity resin systems that contribute greater impact resistance to the fan blade, but whose flow through the fan blade during molding would cause unacceptable movement of the reinforcing fibers. The method entails restricting the flow of the resin system within the preform through selective placement of a resin-impervious material on certain surfaces of the preform, so as to prevent resin loss and fiber movement during the compression molding operation.

  • Patent number: 4764879
    Abstract: The unique signal generating characteristics of a sensing transducer are defined by integrally incorporating an encoded form of the characteristics into the sensing transducer such that the encoded characteristics can be read by a data reader incorporated into a signal conditioner used with the sensing transducer. The encoded data is incorporated as an inseparable part of each operable sensing transducer by being molded or otherwise formed into a connecting cable of the sensing transducer or engraved or otherwise formed onto the barrel of a connector plug for interconnecting the transducer to the signal conditioner. The encoded data portion of the cable is passed through a reader externally mounted on the signal conditioner, or the encoded data on the barrel of a connector plug is read as the connector plug is inserted into a connector socket on the signal conditioner.
