  • Patent number: 10006417
    Abstract: An adaptive air intake joint for an internal combustion engine comprising a molded elastomeric duct body having standing ribs constructed and arranged to provide a continuous and sufficient contact force across the face of a joint of an adjoining duct body. A clamp secured to the duct causes the ribs to provide a continuous and sufficient contact force across a seal surface, eliminating the need for constant tension clamp and improving the air intake joint seal to prevent leakage that is especially common in cold environments.

  • Patent number: 8910979
    Abstract: The pipe repair coupling includes a sleeve and two seal retainers that secure to the sleeve ends to retain corresponding seals therein. The repair coupling is installed about a damaged section of pipe without need for substantial displacement of either portion of the broken pipe or need to dress or otherwise modify the broken ends of the pipe. A seal retainer and seal are placed over each portion of the broken pipe, and the sleeve is slipped over one of the broken pipe portions. The two pipe portions are aligned with one another, and the sleeve is generally centered over the break. The two seal retainers are then locked into place on the sleeve ends by splines inserted into cooperating circumferential grooves in the sleeve ends and retainers, capturing the seals between the seal retainers and corresponding seats and distending the seals to bear against the broken pipe therein.

The seal configuration includes a principal body with a inwardly directed ridge between its tapered ends and a reinforcing ring of different, less permeable material, abutting the ridge and closing off one or more radial ports in the wall of the body. The central body also includes a circumferential gas groove about is periphery, which together with the radial ports, facilitates collection and release of gases permeating the seal body under high down-hole pressures.

  • Publication number: 20110181039
    Abstract: An externally engaging test barrier for use in testing hydrostatic pressure in a plumbing system having two abutting plumbing components. The test barrier includes a barrier body having a first face, a second face, and at least one peripheral engagement for engaging an external surface of at least one of the two abutting plumbing components to hold the barrier body in position across an end of at least one of the two abutting plumbing components. The peripheral engagement extends perpendicularly from the first face or the second face. A removable portion of the barrier body is defined by a frangible connection. The peripheral engagement of the barrier body is incapable of sealing the plumbing system during a hydrostatic pressure test, unless used in combination with a pipe coupling that forms an overlying sealing sleeve.

  • Patent number: 7963569
    Abstract: A novel locking pipe joint for use in fluid-carrying pipe systems is described. The locking pipe joint of the present invention provides a system of joints that will withstand the stresses and forces imposed on a pipe system carrying fluids. The joint is constructed on a push-fit principle. Sealing rings are used to make the joint leak-proof. Splines are provided to sustain the longitudinal forces imposed on the joint, and longitudinal ribs are provided on the outer surface of the joined pipes to withstand the torsional loads. The joint is simple in its construction, easy to assemble in field and cost effective.

  • Patent number: 7878556
    Abstract: A safety release adapter for making a sealed fluid connection with a male connector that is disconnected when a pulling force is applied between the adapter and the connector. The safety release adapter includes a base and a socket. The base receives and secures a first male connector. The socket includes a cavity with a lip at the distal end of the socket. The socket releasably secures a second male connector with the lip inside the socket opening engaging a neck of the second male connector. The first male connector extends into the socket in a sealed interface with the socket such that when the second male connector is secured in the socket with a sealed interface with the socket, the valve buttons of each connector are mutually depressed so the two connectors are in sealed fluid communication.

  • Publication number: 20100283236
    Abstract: A sleeve-shaped anchoring element is disclosed for pipe couplings for connecting flat-ended pipes, with an essentially cylindrical housing and at least one sealing element consisting of rubber-elastic material which is arranged in the housing. The anchoring element is arranged in the housing and consists essentially of individual longitudinal supports which are connected to each other by means of deformable webs and have a C-shaped longitudinal section. The ends of the longitudinal supports are configured as limbs which are angled radially inwards. The free ends of the limbs can be brought into engagement with at least one of the pipes when the pipe coupling is clamped. In each case only one single web is provided between two adjacent longitudinal supports. The two webs of a longitudinal support are arranged offset with respect to each other in the axial direction for connection to the adjacent longitudinal supports, seen in the circumferential direction.

  • Publication number: 20100228188
    Abstract: The device according to the invention for connecting a suction hose has a connecting piece which is designed in such a way that the suction hose can be pushed over a region of the connecting piece in a sealing manner. The device also comprises a sleeve which can be pushed over the aforementioned region of the connecting piece, at least partially covering said piece and leaving room between the sleeve and the connecting piece for the suction hose. The connection between the sleeve and the connecting piece can only be separated by the destruction of at least one of said two parts. The design of the exterior of the sleeve prevents a second suction hose from lying in a sealing manner against the sleeve. A suction hose that is connected in a sealing manner to the claimed device can therefore not be removed without destroying the device. In addition, it is impossible to push a hose with a greater diameter onto the sleeve in a sealing manner.
