  • Patent number: 8794678
    Abstract: In a vibration damper of a turbomolecular vacuum pump, a vacuum tightness function and a vibration damping function are both performed by one or more toroidal rings made of an elastic material. The elastic rings assume a resting configuration while the vacuum pump is not operating and the damper is at atmospheric pressure, and they assume a compressed configuration while the vacuum pump is operating and the damper is under vacuum conditions. In the compressed configuration, the elastic rings are deformed due to a compression force. This deformation of the elastic rings prevents metal-to-metal contact between the vacuum pump and a vacuum chamber to which the pump is connected through the damper.

    Abstract: The invention provides a dual mode hose connection device which can be attached to standard threaded devices such as a typical garden hose faucet, and which offers a quick connection type of attachment as well. In one embodiment, a first dual mode connection piece is threaded onto a faucet. Once connected, standard garden hoses can be attached to the connector using a first mode comprising threaded fittings. In an alternative mode of usage, a second corresponding quick connection piece can be attached to the first connection piece, allowing rapid attachment and rapid removal of the second connection piece along with any desired devices or hoses which are connected down-line of the second piece. Thus, once a first dual mode connector piece is attached to a faucet, then either standard threaded hoses, or quick connect adapted hoses can be used without removing the first dual mode connection piece.

    Abstract: A pipe joint unit includes a first pipe member with a male joint, a second pipe member with a female joint, and a pipe joint member coupling the first pipe member and the second pipe member. The male joint is received in the female joint such that an outer peripheral surface of the male joint is opposed to an inner peripheral surface of the female joint. The pipe joint member includes an engagement part that is elastically displaceable in the radial direction, and engages with the first and second pipe members. The male joint and the female joint have rotation restricting parts on the outer peripheral surface and the inner peripheral surface, respectively, for restricting relative rotation of the first and second pipe members.

  • Patent number: 7387320
    Abstract: A pressure relief cap for a water supply comprises an outer portion defining a front face for generally covering an outlet of the supply. The outer portion includes a seal for being urged against and sealingly engaging a periphery of the outlet. An inner portion includes a connector for coupling and decoupling to an outlet. The inner portion is rotatably coupled to the outer portion such that upon at least partial rotation of the outer portion in a first direction relative to the inner portion the seal is moved axially inwardly relative to the inner portion from a disengaged position to an engaged position to sealingly engage a periphery of an outlet, and upon at least partial rotation of the outer portion in an opposite direction the seal is moved axially outwardly from the engaged position to the disengaged position to thereby permit back pressure within an outlet to vent.

  • Patent number: 7334960
    Abstract: An attachment device for coupling one or more removable turbine components to a carrier of a turbine engine. The attachment device may include a securement structure rotatable about an axis of rotation and including one or more arms for grasping an arm extending from a support structure. A fastener may extend from the support structure and be inserted into a fastener receiving recess in the securement structure for preventing the securement structure from rotating and becoming disengaged from the support structure. The attachment device may also include a fastener retaining device for preventing the fastener, which may be a threaded bolt, from becoming disengaged from the attachment device, traveling downstream in a turbine, and damaging a turbine assembly.

  • Patent number: 7258370
    Abstract: An outlet plate fitting configured for attaching a secondary component to a fluid pipe section. The fluid pipe section includes opposed flanges that define a receiving groove having a bottom surface. The outlet plate fitting includes a main body, an engagement platform connected to and at a distance from the main body, and a bore extending through the main body and the engagement platform. A first surface of the engagement platform faces away from the main body and is a planar surface with a seal member positioned about the bore. A second surface of the engagement platform faces toward the main body and has a ramped surface, such that rotation of the engagement platform in a first direction within the receiving groove causes the planar surface and seal member into sealing engagement with the bottom surface of the receiving groove.

  • Patent number: 7186337
    Abstract: A bracket system holds one or more filters in quick-attach and quick-release fashion. Bracket modules are combined in modular fashion, with tubing or other conduit between the modules, to create a “bank” of filters easily changed in number, arrangement, and flow scheme. Preferably, the bracket system comprises pairs of top modules and bottom modules that capture and support the top end and bottom end of a filter. Filter inlet and outlet ports preferably slide onto and off of cooperating tubes or ports in the bracket modules, for installation and removal of the filters onto/from the modules without tools or threaded connections. A top retaining member preferably pivots off of its respective filter, so that the filter may be lifted up off of its respective bottom module. The bottom modules may be pivotal, so that lifting the filter up from the bracket system is facilitated by allowing the filter top end to also pivot out away from the top module.

  • Patent number: 7100948
    Abstract: A tube coupling has a coupling body with a throughway open at one end to receive an end portion of a tube. A seal encircles the throughway to seal with the periphery and end of the tube and a cap is mounted on the body having a tube locking device rotatably mounted in the cap to engage and hold the tube in the cap. The cap and body have interengaging means which guide the cap on the body in an axial direction along the body with rotation of the cap from a first position in which a tube can be inserted through the cap and into the seal in the throughway and retained by the locking device and a second position advanced along the coupling body from said one end in which the tube end is held positively in engagement with the seal in the throughway. The locking device engages via a ring with the coupling body to resist rotation of the locking device with respect to the body whereby rotation of the cap between said the first and second positions does not cause the tube to rotate.

  • Patent number: 7025385
    Abstract: A coupling connects a first member and a second member. The first member has a first interlocking member extending radially outward from an outer circumferential surface of an axial end. The second member includes a second interlocking member extending radially inward from an inner circumferential surface of an axial end. The axial end of the first member is inserted into the axial end of the second member, such that the first interlocking member is inserted past the second interlocking member. The first and second members are then rotated relative to one another to a locked angular orientation, in which the first interlocking member is interlocked with the second interlocking member to prevent relative axial movement of the first and second members. A key is then inserted into a keyway in the first and second members to lock the angular orientation, thereby coupling the first and second members to one another.
