  • Patent number: 8925969
    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.

    Abstract: A coupling apparatus having coupling body with a mechanical latch assembly. The mechanical latch assembly includes a modified latch plate. The latch plate defines a main portion having a top end and a bottom end and includes an annular aperture disposed between the top and bottom ends. A lever portion is disposed proximate the top end. The lever portion enables the latch plate to move within a coupling body, so as to operate the mechanical latch assembly in a released position and a latched position. A raised edge is disposed about a portion of the annular aperture. The raised edge is disposed proximate the bottom end and extends radially inward of the inner edge defined by the annular aperture. A pin opening is disposed proximate the bottom end opposite of the lever portion. The pin opening is positioned radially outward from the annular aperture, and defines a separate enclosed edge.

  • Publication number: 20100045029
    Abstract: An axially tensioned pipe joint for joining two pipes is disclosed. The pipe joint comprises a first PVC pipe having an outer surface. The pipe joint also comprises a second PVC pipe having a bell end which fits onto the spigot end. The bell end has a plurality of angularly-spaced-apart holes extending radially through the bell end. A set of radial fasteners can be inserted into the holes so as to engage the outer surface of the spigot end to prevent relative axial movement of the first pipe with respect to the second pipe. The radial fasteners have a surface containing a hard material which is harder than the material of the second pipe and roughen the holes during insertion thereby creating a friction fit resisting removal of the radial fasteners. The pipe joint can be used for horizontal direction drilling.

  • Patent number: 7600789
    Abstract: A lockwireless, anti-rotation fitting for connection to a connector. The fitting includes a coupler having a series of circumferential engagement portions disposed about an outer peripheral surface, and a nut receivable coaxially over the outer peripheral surface of the coupler, and which is threadably engageable with the connector. The nut has an opening through which is received the end of a locking mechanism. The locking mechanism end is interferingly engageable with the coupler engagement portions such that with the nut being received coaxially over the coupler outer peripheral surface of the coupler, the nut is threadably engageable with the connector urging the coupler into a sealing engagement with a sealing surface of the connector, and with the coupler being so engaged, the locking mechanism end is interferingly engaged with at least one of the coupler engagement portions delimiting the rotation of the nut relative to the connector.

  • Patent number: 7543855
    Abstract: A hose coupling includes two coupling halves which take a coupling end position by relative rotation against each other about a coupling path of no more than 180°. The hose coupling further includes a locking mechanism that prevents an unintended opening of the coupling. The locking mechanism comprises a latching mechanism, in particular a latching pin mechanism. The latching mechanism is automatically activated in the coupling end position and prevents a relative rotation of the coupling halves against each other. The latching mechanism is preferably configured such that, already before reaching the coupling end position, the latching mechanism is activated so far that it counteracts a relative rotation of the coupling halves in an opening direction.

    Abstract: A reverse osmosis system that includes a housing having an inlet port, a permeate port and a concentrate port. A membrane element is within the housing. The reverse osmosis system further includes (i) a first connector that is connected to the inlet port; (ii) a second connector that is connected to the permeate port; and (iii) a third connector that is connected to the concentrate port. A key is inserted between each of the first, second and third connectors. The key is configured such that the key cannot be inserted between the first, second and third connectors unless each of the first, second and third connectors is properly connected to the respective inlet, permeate and concentrate ports. In some embodiments, the key is configured such that the key cannot be removed from between each of the first, second and third connectors when there is pressure at the inlet port.

  • Patent number: 7452006
    Abstract: A pipe coupling is disclosed which comprises a plug (14) and a socket (12). When the plug is inserted into the socket, the plug first urges sleeve actuators (28) radially outward to axially move a sleeve (22) and, thereafter, urges locking elements (20) radially outward to move the sleeve further. Eventually, the locking elements and sleeve actuators are fitted within a locking recess (14-2) of the plug to securely connect the plug and the socket.

  • Patent number: 7418971
    Abstract: A vending machine and a hose controller system for vending machines wherein the dispenser hose is axially and torsionally controlled to facilitate slight twisting, thereby minimizing applicator tool resistance, and making it easier for users to operate the remote vending tool on the hose distal end. The elongated reinforced applicator hose terminates at the controller, which bridges the hose between the outdoors and the cabinet interior. The controller has an angulated bracket mounted within the vending machine cabinet. A collar assembly secured on the bracket top above a hose feed-through orifice has a terminator, a bushing, and a cooperating yoke that are coaxially secured. The terminator anchors the hose end and is seated within the yoke. A rigid lug projects radially from the yoke. A rigid restrictor surmounts the collar assembly and limits rotation by contact with the lug.
