  • Patent number: 10532428
    Abstract: A method for creating a flexible portion or bending portion within a rigid structure. The method can also be used for creating a flexible structure from a rigid material. The method includes providing a substantially rigid material, such as, but not limited to, metals, alloys, hard plastics, and the like, and selectively removing portions of the rigid material defining a geometric pattern in the rigid material. A bending radius of the flexible portion is defined by the geometric pattern. The rigid structure may be used to create an enclosure, a cover for an electronic device, one or more hinges, or the like.

  • Patent number: 6123363
    Abstract: The assembly of a connection that uses cooperating grooved surfaces to provide an easily disassembled and assembled connection is improved by the use of a centered lip and cooperating groove on the contact faces of the connection halves that engage the faces of complementary connection ends to prevent lateral misalignment while the pipe ends are brought together for axial alignment. The lip extends into the groove to trap a gasket retained within the groove and inhibit extrusion of the gasket between the contact faces under high pressure conditions. The centering device may be used with a clamping mechanism to provide single person assembly of this type of connection despite normal field misalignments. The trapping cavity formed by the faces of the connection ends particularly enhances the pressure capacity of elastomeric gasket applications.

In a second version of the device a shelf like planar projection on the front end of the device engages a planar surface on a nut, again combining with the serrations within the device to prevent fastener loosening. The device is particularly described in use in conjunction with refrigerant system flare nuts so as to prevent loss of refrigerant at these flare nut unions.

  • Patent number: 5570909
    Abstract: A connector for a rigid electrical conduit has an internal cylindrical socket sized to snugly receive the end of the conduit. A spring leaf detent is externally mounted on the connector body, with a free end of the leaf extending through a slot in the connector body side wall. Inserting a conduit into the socket deflects the spring leaf away from the socket axis, thereby generating a resilient stress in the leaf that enables the free end of the leaf to exert a gripping action on the conduit. The grip action can be removed by unloosening a screw that is used to mount the leaf spring on the connector body.

  • Patent number: 5385330
    Abstract: A compression sill-cock flange has a pipe coupling (1) with a flange (8) extended radially outward from a seal end (5). The pipe coupling (1) is straight-threaded internally from an attachment end (3) to a tapered sealing wall (4). The tapered sealing wall (4) is extended inward conically at a select angle from an inside circumferential periphery of the straight threading (2) to a circumferential coupling base (6) that is positioned in sliding contact with an outside periphery of a pipe (12) to which the pipe coupling (1) is attachable. The circumferential coupling base (6) extends to a desired position relative to the seal end of the pipe coupling (5). A set-screw orifice (9) with appropriate threading in a set-screw boss (10) can be provided on the pipe coupling (1). Use means are provided for use in relation to a double-tapered washer (14) and a sill cock (17).

  • Patent number: 5275444
    Abstract: A swivel coupling device is designed for coupling together the mating ends of two tubular fittings forming part of a pressurized fluid, fuel or gas connection system between a fluid, fuel or gas supply and an output device. The device has two relatively rotatable coupling parts with mating flat faces rotatably secured together in face-to-face engagement. Each of the flat faces has a recess with a circular outer periphery matching that of the recess in the other part, and each part has a passageway extending through it to the recess from a point on its outer surface remote from the flat face. Suitable connecting fittings are provided for connecting the passageway on each part to a respective tubular fitting so that the fittings can be swivelled, via dual axes, omni-directionally, relative to one another while fluid, fuel or gas communication between the fittings is maintained through the passageways and recesses of the coupling.

  • Patent number: 5165735
    Abstract: A conduit coupling device includes a tubular casing with front and rear sections of reduced and enlarged diameters. A pair of relatively diametrically movable arcuate clamp members of channel shape with cross webs and flanges is provided, one of the webs having peripherally extending tongues slidably engaging the other clamp member channel. A radial screw engages a tapped bore in the casing rear section and bears on and is clinched to one of the clamp member webs the other clamp member being fixed to the casing. A pair of the casings may be integrally coaxially formed and house similar clamp assemblies or the casing may terminate in an externally threaded coupling tube projecting coaxially forward from the casing front section.

  • Patent number: 5118139
    Abstract: A leak repair clamp for pipe and pipe flanges providing a segmented frame adapted to receive interchangeable annular segmented inserts. All of the inserts provide for interlocking connection with the frame segments but each insert is adapted to fit around one particular diameter cylindrical surface out of a range of different diameter cylindrical surfaces. By selecting particular sized inserts, a single frame can accommodate a wide range of different diameter pipes and pipe fittings. When the insert segments are interlocked into the frame segments, the frame segments are then integrated by bolting threaded studs through flanges to form a unit, which in combination with two interlocked inserts is fastened around and against the cylindrical surface. Thrust restraining set screws are provided to prevent movement of the metal frame relative to the cylindrical surface the frame is fastened around and against.

  • Patent number: 4954004
    Abstract: The invention relates to a releasable coupling between a male element and a female element. The coupling comprises a split clamp ring that is ranged to be received in corresponding annular recesses in the male element and female element, whereby the ring shall have one wedge surface to engage with a support surface in one recess on the male element and another wedge surface obliquely, disposed from the first wedge surface to engage with a support surface in the other recess in the female element. By applying a circumferentially directed force to the end portions of the split ring, it will be possible to achieve a locking engagement between the ring and its matching recesses, thus assembling the male and female elements to each other.
