  • Patent number: 7798177
    Abstract: A transition sleeve is inserted into a transition tube of a vacuum system of a vacuum sweeper. The transition sleeve extends the useful life of the transition tube by sacrificially wearing instead of the transition tube. Such wear arises from abrasive grit and other materials swept up by the vacuum sweeper. The transition sleeve is desirably formed using wear-resistant materials. The transition sleeve can include a flange at one end to allow the transition sleeve to be held in the transition tube without using fasteners or bonding agents. A first portion of an interconnection structure is provided at the other end of the transition sleeve and engages with a second portion of the interconnection structure provided at a first end of an extension sleeve to connect the extension sleeve to the transition sleeve. The extension sleeve allows the transition sleeve to be used with transition tubes of varying lengths.

  • Patent number: 7735468
    Abstract: An electronic throttle device includes a throttle body, a bulge, and a ring. The throttle body includes a bore part having an approximately cylindrical shape. The bore part is connected to an upstream air hose such that the upstream air hose is located on an outside of the bore part and is fastened with a fastening member from an outside of the upstream air hose. The bulge is discontinuously located along an outer circumference of the bore part and has a groove along an outer circumference of the bulge. The ring has a cross-sectional dimension larger than a depth of the groove in a radial direction of the bore part, and is located into the groove to configurate a protruding part that protrudes radially outwardly and extends entirely on the outer circumference of the bore part.

  • Patent number: 7699360
    Abstract: A novel design for the connection of lengths of polyvinyl chloride (PVC) casing. Each length of casing has a male end and a female end. The female end has a narrowing interior diameter with its wider interior diameter at its outermost end sufficient to receive the male end of similar length of casing for connection. The diameter of the female end narrows to a diameter which is less than the outer diameter of the male end. The male end has a lip at its leading edge and is slotted and compressible when forced through the narrowed diameter of the female end. A groove in the interior surface of the female end is sufficient to receive the lip at the leading edge of the male end. When the lip at the leading edge of the male end reaches the groove, it allows the compressed male end to expand with the groove receiving the lip therein. The connected lengths of casing are locked together in this manner.

  • Patent number: 7618069
    Abstract: A tube is insertable into a housing and secured by a collet connector. The tube has a first upset portion for actuating the collet and a second upset portion outwardly from the first upset portion. A retention clip has a first pair of arms which attach to a portion of the housing and a second pair of arms which attach to the tube outwardly of the second upset portion to further secure the tube within the housing. The end of each of the second pair of arms include a ramped surface. If the tube is not fully inserted within the housing before attaching clip, and thus the first upset portion has not fully actuated the collet, the ramps will cam along the second upset portion, thus pushing the tube into the housing and likewise the first upset portion through the collet.

A holder is configured with the housing to receive an evacuated tube. The holder can include a needle hub supporting a needle cannula in fluid communication with a port extending into a fluid well of the housing. A sloped bottom surface of the housing directs fluid to the fluid well. A sidewall extension or support component extends downward beyond the sloped bottom surface to allow the housing to be stood upright on a flat surface. In certain embodiments, the apparatus includes a tubular cavity to provide a recessed location of the needle cannula for preventing accidental needle injuries. An optional cap provides further shielding from needle cannula and safely maintains fluid in housing after use.
