Abstract: A tubing set includes a rigid medical fluid chamber, medical fluid tubing, and a cuff. The rigid medical fluid chamber includes a housing and a tubular fitting extending from the housing. The medical fluid tubing is connected to the tubular fitting such that the medical fluid tubing is in fluid communication with the medical fluid chamber. The cuff is positioned over a length of the medical fluid tubing to inhibit denting of a wall of a length of the medical fluid tubing connected to the tubular fitting and extending beyond the tubular fitting. The cuff inhibits denting when the medical fluid tubing is coiled.

Abstract: An end connector of a corrugated tube made of plastic material has a tubular elastomeric body produced by co-moulding onto an end of the corrugated tube. The elastomeric body includes a connection portion arranged outside the corrugated tube and shaped for connection to an external component, and by an anchorage portion arranged inside the corrugated tube so as to fill grooves of the corrugated wall. A tubular insert which is made of plastic material and is partially incorporated in the elastomeric body and has a stem portion extending inside the corrugated tube and a flange portion which is in abutment with the end of the corrugated tube. The stem portion includes an anchorage zone provided with lateral ducts, in the region of the anchorage zone the stem portion of the insert is attached to the corrugated tube by the anchorage portion of the elastomeric body.

Abstract: A seal requiring no compression type clamp is provided for a drain nipple-hose assembly having a tubular tapered drain nipple projecting from a structure to be drained and a corrugated hose for placing over the drain nipple. The seal includes a hollow flexible inner sleeve and a hollow outer sleeve which is longer than the outer sleeve. The seal also includes an annular wall member which joins an end of the inner sleeve to an end of the outer sleeve. The inner sleeve is stretched over the drain nipple between the drain nipple and the hose so that the inner sleeve sealingly engages the drain nipple and the hose. The outer sleeve surrounds an end of the hose. The wall member has a curved sectional shape, which is concave in a direction in which the drain nipple opens to the hose.

Abstract: Coupling element and method for connecting a connection line to a pipe connection of a washing machine having an external thread. The coupling element includes a first end and a nut with an internal thread arranged in the region of a first end. The nut includes an inner ring, an outer ring, and a slip clutch arranged between the inner ring and the outer ring.

Abstract: The present invention is a coupling used for connecting two rigid vacuum cleaner hoses.

Abstract: An endform connector having an axial bore through which a fluid is conveyed. The endform connector contains a rigid tubular member having a first terminal end, a second terminal end, a channel having an inner diameter extending from the first terminal end to the second terminal end through which a fluid is transported, a stem portion extending a fixed distance from the first terminal end, and at least one sealing member extending radially outward from the stem portion forming a radially increasing surface having a tapered profile terminating in a rim, which exhibits an asymmetric perimeter, adapted to be inserted into an inner channel of a fluid transport hose, wherein the endform connector is sealed to the fluid transport hose; and a connector portion on the second terminal end adapted to be coupled with a fluid conveying structure.

Abstract: A pipe element possessing a longitudinal axis (2) along which a rigid tubular part (3) and a flexible tubular part (4), together constituting a single piece, extend. The rigid part (3) has one end presenting a substantially radial connection surface (8) for connection to an end portion (11) of the flexible part (4), and an additional connection surface (10) on the radial connection surface (8) connecting to the end portion (11) of the flexible part (4), at least a part of the additional connection surface (10) extending substantially parallel to the longitudinal axis (2).

Abstract: The apparatus is a device for removing vehicle exhaust gases from a building. A sealed duct is installed under the floor of a building, and the duct includes a structure for supporting and guiding a hose dolly, a part of which travels within the duct. A flat seal is formed at the top of the duct at the level of the floor by flexible overlapping flaps which are raised and separated by the shape of the hose dolly as it moves along the sunken duct. An air cooled tail pipe coupling permits a hose connection between the hose dolly and a vehicle tail pipe without damage to the hose.

Abstract: An improved assembly, composed of a hard member and a soft tube fitted onto the hard member, for medical uses is formed with a plurality of projections on the side wall of a flange of the hard member. The projections project toward the soft tube side to firmly hold the foremost end part of the soft tube between the projections and a fitting portion of the hard member in a clamped state when the soft tube is fitted onto a fitting portion of the hard member. The foremost end surface of the soft tube may slantwise be cut to define a certain angle relative to the center axis of the assembly such that the foremost end part of the soft tube comes in tight contact with the side wall of the flange when the soft tube is fitted onto the fitting portion of the hard member. The soft tube may be formed with a plurality of cutouts which are arranged along the periphery of the foremost end surface of the soft tube in a spaced relationship.

Abstract: A check valve assembly is disclosed which is inserted in a fluid flow conduit leading from a source of fluid flow to a mechanism utilizing the fluid flow. The check valve assembly comprises a housing having an inlet port and an outlet port that communicate with a central chamber in the housing, and a valve disposed in the central chamber adapted to permit fluid flow from the inlet port through the chamber to the outlet port and prevent fluid flow from the outlet port through the chamber to the inlet port. The housing comprises a first attachment piece associated with the inlet port and adapted to be attached to the fluid flow conduit leading from the source of fluid flow, and a second attachment piece associated with the outlet port and adapted to be attached to one of several adapter elements. Various types of adapter elements are disclosed which include sections for connecting the adapter element to the second attachment piece and to the fluid flow conduit leading to the mechanism utilizing the fluid flow.
