Abstract: A vacuum cleaner hose assembly has a corrugated, flexible hose with fittings at opposite ends for connection to the vacuum cleaner suction inlet and to a cleaning head. A tube or cable extends along the assembly for supply of cleaning fluid or electrical power to the cleaning head. The tube or cable is retained with the hose by means of a U-shape channel provided as a separate member bonded to the outside of the hose. The tube or cable extends within the channel as a loose fit so that it can move along the channel on flexing of the hose, thereby helping maintain flexibility of the assembly.

Abstract: The invention concerns a rapid connection coupling (10) for transferring gases and/or liquid, in particular for coolant filling operations in air conditioning systems. The coupling in question comprises the following elements: a tubular housing (11), an outer sliding sleeve (18) which can slide relative to the housing (11); a number of radially expanding collet chuck elements (15) mounted on the housing (11) and provided with an engaging contour (17) which facilitates connection to a matching connection nipple (30); and a sealing piston (22) capable of sliding centrally inside the housing (11), the said sealing piston being brought into contact with the connecting nipple (30).

Abstract: A connection assembly for an exhaust extraction system which is designed to vent the exhaust from a vehicle tail pipe includes, in combination, three primary components. The first component is an annular sleeve which is constructed and arranged to assemble onto the vehicle tail pipe. A band clamp is used for this connection in order to establish a leak-free interface. Next, there is a nozzle locator ring which slides onto the annular sleeve such that one end of the sleeve extends beyond one side of the nozzle locator ring and the opposite end of the sleeve extends beyond the opposite side of the nozzle locator ring. There is an offset portion intermediate the ends of the annular sleeve which serves as an abutment for the nozzle locator ring.

Abstract: A vacuum cleaner tube shaft having a first tube shaped part (11) and a second tube shaped part (12). The first part is slidably arranged in the second part and is adapted to be releasably locked to the second part in a desired position. The second part (12) includes two sections (15, 16) which are connected to each other via a pivot (17). When the first part (11) is inserted in the two sections (15, 16), the two sections are aligned with respect to each other. When the first part is inserted into only one section (15) of the second part, the sections (15, 16) can be positioned in a desired angular position with respect to each other.

Abstract: When first and second coupling pieces are tightened in the axial direction thereof by turning a screw member, the second coupling piece is prevented from being turned together with the screw member, thereby enhancing sealing property, cleanliness and workability. A thrust bearing is interposed between a pressing surface of the screw member and the second coupling piece.

Abstract: A process for fusion jointing or joining of pipe sections includes the steps of covering planed ends of the pipe pieces with an electric socket. The electric socket has a heating device disposed therein, and a heating output of the socket is such that an effective butt-jointing occurs between the pipe pieces. A bellows can be placed within the pipes to prevent collapse thereof, and to improve an inner bead quality of the pipe parts.

Abstract: A push-in coupling for pipes contains a sleeve body (2) and a holding means, especially with a clamping body (6), for connecting a pipe end (3, 4) to the sleeve body (2). This push-in coupling permits proper handling with little effort during assembly, and insofar as possible prevents the danger of faulty assembly. A sliding body (50) is disposed within the sleeve body (2), the sliding body (50) being made independently of the holding means. The sliding body (50) contains a striker (52) which upon insertion of the pipe end (3, 4) is pushed over an edge (60), and upon reaching a given depth of insertion of the pipe end (3, 4) strikes against a surface (62) producing a detectable signal such as an acoustical signal and/or a vibration signal.

Abstract: A vibration isolating flange mount assembly for a pipe has a vibration abbing gasket and fastener recesses having a vibration dampening material disposed therein to provide a fluid seal between the pipe and a flooded structure and to isolate pipe vibrations.

Abstract: A pipe connecting assembly and method for joining two lengths of steel pipe in the field without the need for welding the connection includes a pair of tubular members both having cylindrical exterior and interior surfaces that substantially conform to the exterior and interior surfaces of the two lengths of steel pipe.

At one end of the other tubular member a female connector is formed. The female connector has a plurality of flat annular ridges and tapered and flat surfaces formed thereon. In employing the tubular members in connecting the two lengths of steel pipe, the ends of the members opposite the male and female connectors are first welded to opposed ends of the steel pipe.

Abstract: The invention provides a method for sealing and locking together interconnectable pipe for industrial, commercial and other uses. The sealed locking joint is comprised of the smaller end of one pipe, spigot end, which is inserted into the larger end of the receiving pipe, bell end. A sealing gasket and a corresponding locking gasket are utilized to retain the pipe in its assembled position and prevent leakage of material at the joint. Alternatively, a sleeve may be utilized into which is inserted the spigot ends of the pipe, said sleeve having positioned within it sealing gaskets and locking gaskets similar to the configuration utilized in the bell end of the alternate assembly.

Abstract: The disclosure relates to a tube coupling comprising a coupling body having a throughway open at one end of the body to receive a tube. A collet is located in the throughway having an annular element and at least one radially resilient finger extending axially from the element toward said open end of the throughway. The coupling body has a stop face directed along the throughway axis away from said open end and the distal end of the finger has on its inner side a projection to engage a feature on the tube and on its outer side a first, axially facing abutment directed towards the open end of the throughway to engage with the stop face and a further, radially facing abutment engageable with the coupling body when the axially facing abutment engages the stop face to constrain the distal end of the finger against radial outward movement and thereby to prevent release of the projection on the finger from the feature on the tube and release of the tube from the coupling body.
