  • Patent number: 10844981
    Abstract: A press fitting for pipes includes a socket with an insert opening for a pipe end. An annular groove-shaped space present in a press wall part of a press region is delimited by a limitation edge. A gripping ring is placed in the groove-shaped space. The press region is deformable from a non-compressed state a compressed state by a radially inward directed pressing action causing the press wall part to radially compress and the gripping ring to grip the pipe end. A check ring is provided which has one or more break segments and a coupling part. The break segments can be forced to break free by the pressing action, while the coupling part then comes to lie visible at least partly in between the limitation edge and the pipe end.

  • Patent number: 10447678
    Abstract: Secret information, such as seeds, codes, and keys, can be automatically renegotiated between at least one sender and at least one recipient. Various mechanisms, such as counters, events, or challenges, can be used to trigger automatic renegotiations through various requests or communications. These changes can cause the current secret information to diverge from older copies of the secret information that might have been obtained by unintended third parties. In some embodiments, a secret can be configured to “decay” over time, or have small changes periodically introduced that can be determined to be valid by an authorized party, but can reduce the effectiveness of prior versions of the secret information.

  • Publication number: 20140197633
    Abstract: A crimp fitting comprises a female socket that is configured to be crimped to an end portion of a hard tube. The socket comprises an annealed annular wall that has an inner cylindrical surface portion and at least one annular sealing portion. The cylindrical surface portion lies axially between the socket opening and the annular sealing portion, and has a diameter matched to the OD of the tube. The annular sealing portion has an innermost diameter that is greater than the diameter of the cylindrical surface portion. As the end of the tube is inserted into the socket, the tube cannot slideably contact the annular sealing portion. Thus, the annular sealing portion will not be damaged by the insertion of the tube. Thereafter, the annular sealing portion is radially crimped and ultimately contacts and deforms a portion of the tube in a manner creating interlocking geometry and a pressure seal.

    Abstract: Barbed fittings having elongated bodies defining open ends and an internal fluid carrying passage interconnecting the ends are disclosed herein, with at least one end having a barb with a reduced outer diameter and/or taper angle to reduce the amount of insertion force necessary to install the fittings, thereby making the fittings easier to insert in conduit and/or other fluid carrying components. To also make the fittings easier to install, a barbed fitting insertion tool is disclosed having a body defining a fitting receptacle in a front portion of the body and a handle portion in the rear portion of the body for gripping and inserting fittings located in the fitting receptacle into conduit. The fitting receptacle having a locking mechanism for securing the fittings to the tool and preventing unintentional removal of same from the tool.

  • Publication number: 20120153614
    Abstract: For forming a clamping ring first the pipe is extruded. The extruded pipe is cut to form a pipe part. While extruding the pipe, its inner diameter is formed smaller than the outer diameter of a pipe onto which the clamping ring is positioned before making a pipe connection. The inner diameter of the pipe part is made larger by removing material from the inside of the pipe part but only over part of the length of the pipe part such that a stop edge is formed. The clamping ring is used on a pipe when making a pipe connection.

  • Patent number: 8136788
    Abstract: A coupling element has a first interface, which is adapted to mechanically connect the coupling element to an actuator, a second interface, which is adapted to mechanically connect the coupling element to a valve, and a deformable portion, which is shaped in such a manner, that, as a result of a compression along an axial direction of the coupling element, the deformable portion irreversibly bends such that a projection is formed. Thereby, the projection is adapted to permanently engage with an annular groove formed at the actuator, such that the coupling element and the actuator are connected with each other in a non-detachable but rotatable manner.

  • Patent number: 8113550
    Abstract: An adapter integrates a tail piece and connection for coupling to plumbing fittings utilizing a union nut or flange and provides a press-fit connection to the tail piece for installation in the system. The method of manufacturing the adapter comprises the steps of forming a flange on a section of conduit; placing a threaded union nut or mounting flange over the flange fitting; roll-forming an internal, concave annular recess into the section of conduit extending from the nut and inserting an O-ring into the recess for completing the adapter. The adapter can then be sealably attached to a plumbing fitting, such as a valve or the like, utilizing a conventional flat gasket between the flange of the adapter and the plumbing fitting. The installation is completed by inserting a conduit into the adapter to clear the O-ring and crimping the bead formed by the recess to complete the sealed connection.

    Abstract: The invention relates to a microfluidic device including a chamber having a fluid inlet, a fluid outlet and a sealable port. In some embodiments, the fluid inlet and the fluid outlet may be positioned to direct fluid flowing from the fluid inlet to the fluid outlet through the chamber. Various embodiments may include a sealable port which may be aligned with the chamber to allow material to be placed directly into, or removed from, the chamber from the exterior of the device when the sealable port is open, and to inhibit and/or prevent fluid escaping through the sealable port when the port is sealed.

  • Patent number: 8038181
    Abstract: A connecting arrangement for fluid-conducting tubes (1, 2) has a further fluid transporting component (16). The fluid-conducting tube (1, 2) has at least one collar (3, 4) facing radially outwardly which can be clamped against the further fluid transporting component (16) with the aid of a holder (5). The holder (5) has at least one U-shaped lateral receptacle (6, 7) formed by two arms (12). The predetermined length of the arms (12) is dimensioned such as to enclose more than half of the fluid-conducting tube (1, 2) during plastic deformation. The U-shaped receptacle (6, 7) has at least one relief region (13) in which holes, grooves, cavities or other material reductions are arranged. The cross section of the arms (12) changes little during deformation due to the relief regions because upset material can flow into the same.

  • Patent number: 7980602
    Abstract: A pipe fitting facilitates joining of a high-density polyethylene (HDPE) pipe to a polyvinyl chloride (PVC) pipe. The fitting has a HDPE body. A ring-shaped PVC insert is positioned within an inner surface of the body at one opening of the body. An inner surface of the PVC insert is threaded so that a PVC pipe that has a threaded outer surface can be screwed into the PVC insert. A compression ring is installed over the outer surface of a portion of the body that surrounds the PVC insert. Prior to installation, the inner diameter of the compression ring is smaller than the outer diameter of the portion of the body that surrounds the PVC insert. For this reason, when the compression ring is installed, the compression ring compresses the portion of the body that surrounds the PVC insert, holding the PVC insert within the body.
