  • Patent number: 10025164
    Abstract: An add-on lens assembly supporting an add-on lens for a camera includes a locking mechanism actuatable by the user in order to increase the attachment force between the lens and the camera. The add-on lens assembly may include a rotatable lock ring having a cam pin that navigates along a surface of a cam such that when the lock ring is rotated, the cam pin causes the cam to translate axially. Axial translation of the cam may compress a spring within the assembly and increase the attachment force between the lens assembly and the camera. The increased force between the add-on lens assembly and the camera may provide additional support for large or heavy assemblies.

    Abstract: A socket that receives and locks a plug includes a cylindrical socket body having a plug-receiving part, a first through-hole, and a second through-hole rearward of the first through-hole, a plug-locking element movable in the first through-hole between a locking position for preventing the plug from being pulled out and an unlocking position for allowing the plug to be pulled out, a sleeve-operating element movable in the second through-hole, a sleeve provided around the socket body and urged to be displaceable in the longitudinal direction, and a collar urged in the socket body. The socket body has a guide portion located forward of the collar and adjacent to the forward end edge of the collar to prevent the forward end of the plug as inserted into the socket from engaging with the forward end surface of the collar and to guide the forward end of the plug into the collar.

  • Publication number: 20130015656
    Abstract: A high-pressure connection device for pipe and hose lines with a connection body and a pipe-like end piece insertable into the connection body, including a union nut externally mounted to the connection body, which can be rotated between a released position and a mounted position. Form-locking designs, which act like a bayonet coupling, are arranged on the connection body and union nut in the form of projections on the union nut as well as in the form of interlocking contours formed on an end extension of the connection body for the locking reception of the projections when rotating the union nut. A security element is movable between a secure position and a release position for rotation of the union nut in order to prevent unintentional reverse rotation of the union nut.

  • Patent number: 8267434
    Abstract: Hose coupling incorporates male part and a female part being provided with elements which in corporation with a slide axially displaceable sleeve on the female part renders possible pressure relief at disconnection. These elements are constituted by an angular locking pawl one portion of which is insert able in an axial groove in the female part and has such length that always at least some part thereof is surrounded by the sleeve. The other inwardly directed part of the locking pawl has such length that it extends into the groove of the male part when locking pawl is influenced by the sleeve. The locking pawl is a combined element. To lock the male part when the coupling is connected and lock the male part in an alternative position when it's pressure relieved.

  • Patent number: 8256803
    Abstract: A socket that receives and locks a plug has a cylindrical socket body, a plug-locking element provided in a first through-hole of the socket, a sleeve-operating element provided in a second through-hole of the socket, a sleeve, and a collar. The collar is movable between a first position (FIG. 1) and a second position where the collar allows radially inward displacement of the sleeve-operating element by the plug inserted into the socket. When the plug is inserted into the socket, first, a locking element-pushing portion of the plug pushes out the plug-locking element into a first recess of the sleeve and causes the plug-locking element to displace the sleeve rearward. As the plug is further inserted into the socket in this state, the plug engages and pushes the collar from the first position to the second position.

  • Patent number: 8251407
    Abstract: The female quick coupling element is fitted with at least one locking member (40) movable in a housing (27) between a first position in which a fraction (46) of the locking member projects out from the housing (27) and a second position in which the fraction (46) of the locking member is disengaged from a groove in a male element endpiece (11) engaged in the female element. A control ring that is slidable relative to the body of the female element parallel to its central longitudinal axis (XA-X?A) is suitable for moving the locking member between its first and second positions. The locking member (40) is provided with at least one surface (42, 43) in the form of a portion of a sphere. The locking member moves between its first and second positions by pivoting about a fixed axis passing through the center of curvature (C40) of the surface (42, 43) in the form of a portion of a sphere of the locking member (40) and perpendicular to the central longitudinal axis (XA-X?A) of the female element.

  • Patent number: 8197225
    Abstract: Slip joint clamps are installed against guide ears of diffusers at jet pump slip joints. Clamps may prevent vibration and/or movement in the slip joint while not being rigidly attached to the diffuser. Clamps include a compression flipper pressing against a guide ear of the diffuser in a substantially radial direction, a biasing member between the compression member and guide ear that presses the flipper against the guide ear, and supporting structures that hold the flipper and biasing member to the inlet mixer about the guide ear. Systems of slip joint clamps are installed against several guide ears of a single diffuser. Each clamp may radially stabilize the diffuser and inlet mixer while permitting upward relative movement of the inlet mixer. Placement and tensioning of clamps in such systems may be varied so as to prevent or reduce vibrations and/or oscillations between an inlet mixer and diffuser.

  • Patent number: 8191932
    Abstract: A coupling for liquid and gas applications has a valve cartridge loaded from a front end of the coupling. The valve cartridge includes a valve body, a valve member, and a valve spring. The valve member is within the valve body and the valve spring coaxially surrounds the valve member and is disposed between the valve body and the valve member. An aperture in the valve body allows the valve member to pass through the valve body. A stop ring is disposed between the valve cartridge and the front-end portion to secure the valve cartridge in the valve cavity. The valve cartridge is secured in a valve cavity of the coupling by the stop ring. The valve member includes a valve that is opened when a mating coupling is inserted into the coupling. The valve also operates to shut off the flow when the couplings are disconnected.
