  • Patent number: 6086109
    Abstract: A conveying pipe for hydraulically transporting solids, such as sand, gravel or also concrete is composed of a straight or curved pipe portion and of coupling flanges at the ends of the pipe portion, wherein the coupling flanges protrude radially above the outer surface of the pipe portion. The outer end faces of the coupling flanges which face away from each other are each located in the transverse planes of the end faces of the conveying pipe. The coupling flange located at the end of the conveying pipe on the inlet side has a greater width than the coupling flange arranged at the end on the outlet side.

  • Patent number: 6086115
    Abstract: A coupling for connecting a hose to a container. The coupling is made up of a tubular body that telescopically receives a ferrule. The coupling has a stop flange with diametrically spaced recesses and the ferrule has diametrically spaced inwardly extending projections that pass through the recesses in the stop flange when the ferrule is inserted onto the coupling. The ferrule is then rotated so that the projections overlay the stop flange and prevent the ferrule from being removed during shipment or storage of the couplings. The ferrule can be swaged or crimped to the hose for holding the hose to the coupling in the conventional manner.

  • Patent number: 6086110
    Abstract: A vibration decoupling exhaust connector is provided having a flange for mounting the connector to a flange or housing surface of an exhaust system component, such as an exhaust manifold of an internal combustion engine. A liner tube is resiliently supported in the flange, by a vibration damping resilient metal mesh ring.

  • Patent number: 6082780
    Abstract: The process of this invention will involve overmolding a thermoplastic or rubbery polymer composition over a thermoplastic hollow tube and a core insert to form a hollow overmolded coupler after the removal of the core insert, the tube entering the coupler at an angle which is less than 90.degree. so as to minimize any freezing of transported water which may reside in the coupler. The combination of the above polymers must satisfy at least two simultaneous conditions. First, the inserted plastic tube must not soften and begin melt flow to the point where it looses structural integrity during the molding processing and second, the overmolded polymer must be capable of forming an essentially leak-proof interface between the coupler and the plastic tube, preferably through either a chemical and/or physical bond between the plastic tube and the overmolded plastic.

  • Patent number: 6082784
    Abstract: There are provided a connection structure and process for connecting an eye-joint and a slender metal pipe, which is enabled by making the welding operation completely unnecessary to eliminate the working troubles and a fear of cracking or breakage, as might otherwise be caused by deteriorations in the mechanical properties in the vicinity of the connection end portion, which can use the eye-joint body and the metal pipe, as plated with a corrosion-resistance substance or coated with a resin in advance, to improve the productivity drastically thereby to ensure the connection with neither axial nor circumferential movement, and which can connect a metal pipe, if necessary, as having a diameter larger than the width of the eye-joint body.

  • Patent number: 6082779
    Abstract: A releasable connector for connecting tubing such as used in fuel lines has a display member to indicate when positive locking has occurred. The display member member is attached to the outside of the housing of the connector. The display member has a strap supporting a cover portion. The cover portion has a pair of resilient flanges which are insertable into an opening in the housing of the connector. The flanges extend into a chamber to engage an annular ring of a conventional male tube end. The annular portion of the tube end displaces the flanges of the display member after passing through a locking member contained in the housing of the connector. In this way, the tamper indicator indicates that the tube end has been positively received in the locking position.

  • Patent number: 6079749
    Abstract: A preassembled fitting including a body, a nut and a collet positioned within the nut. The nut is threaded on the body a predetermined distanced to allow the installer to snap the corrugated tubing into the nut and engage the collet. The nut is then further tightened to seal the body to the corrugated tubing. A tapered surface on the body engages the cut end of the corrugated tubing and flares the cut end of the corrugated tubing. The fitting will make a metal to metal seal by folding the convolutions of the tubing back against itself creating a double flare.

  • Patent number: 6073976
    Abstract: A pipe fitting (1) for connecting a metallic pipe line (10), including a pipe union (4), which contains a receiving opening (8) for the pipe line (10), a swivel nut (6), which can be threadedly connected with the pipe union (4), as well as metallic cutting ring (18), which is disposed between the pipe union (4) and the swivel nut (6). The cutting ring (18) with an outer cone (30) acts jointly with an inner cone (28) of the pipe union (4) in such a manner, that, when the swivel nut (6) is tightened, it cuts into the material of the pipe line (10) with at least one cutting edge (32) and generates a form-fitting junction. The cutting ring (18) includes--where it joins an outer cone (30)--an essentially radial contact surface (38) for the purpose of limiting the tightening force, when it comes into contact with a face surface (40) of the pipe union (4).
