  • 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.

  • Patent number: 10378221
    Abstract: A drywall mud applicator wheelless control tube is provided. The drywall mud applicator wheelless control tube has a plastic component (in an embodiment) having a rubber o-ring or spring which provides pressure to a slanted cylindrical ledge protrusion which allows the control tube to slide up and down a main mud applicator tube without the need for wheels on the control tube. As a result, the wheelless control tube increases the sliding and smoothness of the control tube as it slides over the main mud applicator tube.

  • 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.

  • 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.

  • Publication number: 20110306081
    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: 8061423
    Abstract: An assembly for use in a wellbore formed in an earth formation, comprising an expandable tubular element and an outer structure having first and second portions arranged at a distance from each other, the portions being restrained to the tubular element in a manner that the distance changes as a result of radial expansion of the tubular element, the outer structure further having a third portion arranged to move radially outward upon said change in distance between the first and second portions, wherein said radially outward movement of the third portion is larger than the radially outward movement of the tubular element as a result of radial expansion of the tubular element.

  • 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.
