  • Patent number: 11799251
    Abstract: A power transfer system to facilitate the transfer of electrical power between tree trunk sections of an artificial tree is disclosed. The power transfer system can advantageously enable neighboring tree trunk sections to be electrically connected without the need to rotationally align the tree trunk sections. Power distribution subsystems can be disposed within the trunk sections. The power distribution subsystems can comprise a male end, a female end, or both. The male ends can have prongs and the female ends can have voids. The prongs can be inserted into the voids to electrically connect the power distribution subsystems of neighboring tree trunk sections. In some embodiments, the prongs and voids are designed so that the prongs of one power distribution subsystem can engage the voids of another power distribution subsystem without the need to rotationally align the tree trunk sections.

    Abstract: Apparatus and methods for endoscopic colectomy are described herein. A colectomy device having a first and a second tissue approximation device is mounted on a colonoscope separated from one another. During deployment of the colectomy device, a diseased portion of the colon is positioned inbetween the tissue approximation devices. The tissue approximation devices are radially expanded such that they contact and grasp the colon wall at two sites adjacent to the diseased portion of the colon. The diseased portion is separated from the omentum and is transected using a laparoscope or is drawn into the colonoscope for later removal. The tissue approximation devices are then urged towards one another over the colonoscope to approximate the two free edges of the colon into contact together where they are fastened to one another using the tissue approximation device as a surgical stapler to create an end-to-end anastomosis.

The pipe connection further includes a first pipe, a second pipe and an interior part at an end of the first pipe. The interior part is enveloped by a bell part at an end of the second pipe. The pipe connection further includes at least one lamellar ring held in an annular groove in either a) a radially outer surface of the interior part or b) a radially inner surface of the bell part. The at least one lameller ring is tensioned against either a) the radially outer surface of the interior part or b) the radially inner surface of the bell part. Either a) the radially outer surface of the interior part or b) the radially inner surface of the bell part is constructed as a concave surface. The at least one lameller ring is tensioned against the concave surface.

  • Patent number: 7416395
    Abstract: A sleeve connecting a refrigerant pipe to a sealed compressor container has a reduced outer dimension and an inner step that accommodates the refrigerant pipe. An end of the refrigerant pipe abuts the inner step to accurately locate the refrigerant pipe to permit the refrigerant pipe to be secured in an desired relationship with the sleeve. The sleeve is attached to the container with increased accuracy and less chance of damage to the container through deformation during the attachment process. The sleeve and container may be composed of iron, while the refrigerant pipe may be composed of copper, so that the more rigid sleeve can accurately couple the less rigid refrigerant pipe to the container.

  • Patent number: 7410192
    Abstract: A pipe coupler for use in connecting a pair of automotive exhaust pipe ends each having a circumferential rib. The pipe coupler includes a ribbed band and internal split sealing sleeve along with a tightening mechanism for clamping the band and sleeve over the pipe ends. The sealing sleeve fits within the band and both the sleeve and band have a pair of ribs positioned to fit over the ribs on the pipe ends. The sleeve extends circumferentially from a first end to a second end, and includes a tongue-and-groove sealing configuration located axially inwardly of the ribs at the first and second ends. Each tongue has a particular construction that accommodates larger clamp opening dimensions required to fit the coupler over the pipe ribs during assembly. The sleeve can include inwardly protruding sealing beads that help prevent leakage of exhaust gases from the pipe junction.

  • Patent number: 7404686
    Abstract: A snap-fit arrangement for joining component parts, such as tubular sections and fittings includes a male coupling and a female coupling. A portion of the male coupling extends from one component part and includes cantilever prongs with enlarged heads. The exposed portion of the male coupling and prong heads are structured and disposed for insertion into another component part and through the female coupling until the prong heads exit the inner end of the female coupling and snap outwardly into locked engagement, thereby releasably connecting the two component parts.

  • Patent number: 7381454
    Abstract: A tubular product has a tubular base layer, a tubular innermost layer made of plastic by continuous extrusion, and a tubular tie layer of foamed plastic between and adhered to the base layer and the innermost layer. The tie layer is made of melt processable adhesion plastic, is extruded simultaneously with the innermost layer against the base layer, and has better adhesions to the base and innermost layers than the base and innermost layers have to each other.

  • Patent number: 7338095
    Abstract: A connector for connecting a terminal end of a heating duct to a heating duct board, the connector including an annular cylindrical portion with an outer surface and a maximum outer diameter and a flange extending radially outwardly from the outer surface of the annular cylindrical portion. The flange has a dimension greater than the maximum diameter forming an abutment against which a lower edge of the heating duct board abuts. The flange also has at least one sleeve for receiving a zip tie. The connector includes retention means for securing the connector to the heating duct board with the heating duct board encircling the annular cylindrical portion and being in abutting engagement with the flange. The retention includes at least one zip tie mounted through the at least one sleeve of the flange and engageable in a mouth of the heating duct board to which the connector is secured.
