  • Patent number: 9080705
    Abstract: When releasing a connection between a second tube member and a first tube member, a ring member is moved, whereby an inclined surface of a bump part and an inclined surface of a bump part of a cam part slide, and a stopper rotates from a coupled position to an uncoupled position. Thus, a coupling between a leading end part of a claw part of the stopper on the second tube member, and a coupling surface of a coupling-accepting part on the first tube member is released. In connecting the first and second tube members, when the first tube member is pushed into the second tube member with the ring member in the locked position, the claw part of the stopper is elastically deformed, whereby the leading end part of the claw part rides past the coupling-accepting part, and couples to the coupling surface of the coupling-accepting part.

    Abstract: A spray shield for the pipe connection flange of pipes carrying hazardous fluids. A band composed of metal or other suitable material encompasses a pipe flange and supports a spray diffusion mesh or device so that any spray of pressurized leaked fluid is coalesced to drops or streams of leaked fluid which descend by gravity for collection rather than being sprayed into the environment in the vicinity of the leaking flange joint. The spray shield band is secured about the flange by an over-center latch mechanism that tightens the band and spray diffusion mesh around the flange connection. A locking pin or lockout device is inserted through aligned holes of the latch mechanism when closed and functions to secure the latch against release and movement from its latched position.

  • Patent number: 5943461
    Abstract: An optical module is packaged using one or more internal fiber connections which are arranged to minimize the likelihood of internal connection damage when the module is installed on a circuit board. The module includes at least one external connector arranged on a side of the package, and a submount within the package for supporting a component such as an optical source or an optical detector. An optical fiber is connected within the package from the submount to a connector interface of the external connector. The end of the fiber at the connector interface has a preformed connector thereon which engages a ferrule associated with the interface. The other end of the fiber is attached to the submount for optimal coupling efficiency. The fiber may undergo a bend of about 90.degree. or 180.degree. from its first end to its second end. In order to accommodate the fiber bend, the component submount is positioned within the package in a location remote from the external connector.

  • Patent number: 4125279
    Abstract: This invention relates to a hose coupling on the body of which is rockably mounted intermediate its ends a locking member, one end of which constitutes an operating handle. The other end of this locking member is of such a configuration as to constitute a stop which is manually rockable by the operating handle out of the pathway of the guard arm of the other one of a pair of hose couplings to be manually coupled prior to rotating the two hose couplings to the fully coupled position. The configuration of the stop is such that, upon the pair of hose couplings reaching their fully coupled position, this stop will be disposed in such a position in the pathway of the guard arm of the other one of the pair of fully coupled hose couplings as to prevent unwanted uncoupling of the two coupled hose couplings. Upon manual rocking of the locking member in one direction by the operating handle, the stop will be lifted out of the pathway of the guard arm of the other one of the pair of coupled hose couplings.
