  • Patent number: 6428052
    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: 6422610
    Abstract: A deformable fluid supply line for use on a semiconductor fabrication machine is described which includes a generally S-shaped expandable joint connecting between two straight conduit sections for providing full communication thereinbetween and for providing stress absorbing characteristics such that the expandable joint can be stretched or otherwise deformed by at least 2 cm without breaking connections with the two straight conduit sections. When the generally S-shaped expandable joint is provided with a length of at least 10 cm, a deformation of at least 3.5 cm can be tolerated by the expandable joint without causing failure or otherwise damages in the connections with the two straight conduit sections. The deformable fluid supply line can survive an earthquake of the magnitude of Richter 5 scale. The invention further discloses a method for connecting a deformable fluid supply line to a fabrication machine by using an S-shaped joint connected in between two straight conduit sections.

  • Patent number: 6416087
    Abstract: The invention relates to a connecting branch (10) comprising a replaceable insert part (20) which is placed in a chamber (22) in a sealed manner. Said chamber is open in the front and is located inside the connecting branch (10). A ring-shaped sealing surface having a rotating sealing bead (16) is arranged on the insert part (20). The bead can be pressed into a front surface of an axial sealing ring (14) made of a soft metal, said surface being situated opposite the connecting branch, when coupling a connecting nipple (12) to the connecting branch (10). The insert part (20) is advantageously sealed in the chamber (22) by a second axial sealing ring (32) whose sealing surfaces also having sealing beads (34, 36). The insert part (20) can be merely replaced when the sealing bead (16) is corroded or damaged. As a result, a difficult subsequent fashioning of the standard seal bead (16) on the connecting branch (10) is unnecessary.

  • Patent number: 6416086
    Abstract: The invention proposes an articulated arm for transferring fluid products comprising two tubular sections (7, 8+2) connected to each other by a rotating joint (3) with a horizontal axis, and one of which, mobile in rotation, has an angular reference configuration in which it is balanced despite the effect of gravity. A balancing device (4, 10) compensates for variations in the effect of gravity on this mobile tubular section as a function of the orientation of this vis-a-vis the vertical, it is mounted between a fixed reference portion and a linkage portion of the mobile tubular section which is at a distance other than zero from the axis of rotation; it includes a spring (10) which tends to return the mobile section to its angular reference configuration (it is then idle) and applying to the mobile tubular section a force which is approximately proportional to the distance between this linkage portion and the location of this linkage portion in the angular reference configuration.

  • Patent number: 6412826
    Abstract: A quick connector for connecting fluid lines includes a first connector having a housing for receiving a tube carrying spool. The spool sealingly engages an endform on the tube to form a metal-to-metal seal. A retainer in the form of ring having a plurality of angularly and radially extending, resilient legs extending therefrom and terminating in end pads is mountable in the housing in engagement with the spool with the end pads disposed in an annular, inward facing channel in the housing. A pop top is slidable along the tube to bias the retainer legs radially inward to allow insertion of the retainer into the bore in the housing and then is removed to allow the legs to snap radially outward bringing the end pads into engagement with housing channel. An assurance clip is mountable interiorly between the legs of the retainer and the spool to maintain the retainer legs in a radially outward position in engagement with the channel in the housing.

  • Patent number: 6409227
    Abstract: A fast rotation joint is disclosed. The fast rotation joint is engaged between a machine body and a joint of the transferring flexible tube. The fast rotation joint includes mainly a first main body, a second main body, and a third main body. A drain-preventing pad is illustrated between the first main body and the second main body. The drain-preventing pad is used to prevent air from drainage so that the pressure will be insufficient. A plurality of rollers are mounted between the second main body and the third main body for preventing the deformation from the engagement of the machine body with the transferring flexible tube so as to increase the lifetime of the transferring flexible tube and the joint.

  • Patent number: 6409219
    Abstract: A system for preferable use in gravel packing is disclosed which includes a plurality of transport tubes which are mounted outside of gravel pack screens. The multiplicity of shunt tubes cover a particular zone so that the tubes have a varying length to deposit gravel at different portions of the zone. The tops of the tubes are preferably sealed until ready for use and activated by applied pressure. In the preferred embodiment, rupture discs are found at the tops of each of the tubes, set for different pressures so as to open up the transport tubes to the lower most portion of a particular zone and later in sequence to the higher-most portion. The transport tubes are affixed to each section of pipe and are made up when two sections of pipe are made up to alignment marks. When the marks are aligned, the transport tube segments from each pipe section are in an aligned and sealed relation while the tool joint is properly torqued.

  • Patent number: 6406069
    Abstract: A coupling apparatus couples a container of colorant to a feeder structure for a polymer processing machine. The coupling apparatus includes a tubular structure with an outlet portion that engages the feeder structure, and an inlet portion that receives and supports the container above the outlet portion. The inlet portion has an upright position in which it supports the container in an overturned position from which the colorant can flow out of the container under the force of gravity. A joint, which is preferably a hinge, supports the inlet portion for movement to an overturned position. The inlet portion can then receive the container in an upright position from which the colorant will not spill from the container. Preferably, a releaseable locking device interacts with the joint to retain the inlet portion of the tubular structure releaseably in its upright position.

  • Patent number: 6378910
    Abstract: When running pipes or lines through a wall of a structure a hole is drilled in the wall during fabrication of the structure and then the line or pipe is run through the hole and to the outside of the building. Hose bibs or sill cocks typically include a faucet-like member and a base with notches located on opposite sides of the base. The hose bib attaches to the pipe and the hose bib is secured to the outside wall of the building usually by screws. A problem which frequently occurs with this practice, however, is that the pre-formed hole is too large so that the hose bib or sill cock cannot be secured to the wall. That is, there isn't anything to which the screws may attach. The present invention seeks to correct this problem by providing a flat, essentially diamond-shaped plate with a plurality of holes located therein. A hole larger than the other holes is located in the center of the plate.
