  • Patent number: 11047517
    Abstract: A modular, aerogel-based vacuum insulated pipe section comprising an outer conduit; an inner conduit concentrically disposed within the outer conduit with aerogel insulation and a condensable gas being disposed in the insulation space between the concentric conduits. As a stand-alone pipe section, the insulation space is at a pressure within the range of from about 100 microns Hg to about 1000 microns Hg. However, in operation, when a cryogenic fluid is traversing the inner conduit, the condensable gas condenses and the pressure within the insulation space is further reduced to range of from about 1 microns Hg to about 5 microns Hg. The vacuum insulated pipe section further includes a coupling arrangement disposed on a first end of the inner conduit and a second end of the inner conduit, the coupling arrangement configured to engage or mate with a corresponding end of another modular vacuum insulated pipe section.

The chromatography-electrospray device contains a chromatography column, a pre-column, a spray emitter, or other fluidic component imbedded within one or more inserts. The inserts are robotically placed in receiving hardware, and a “plug and play” compression fitting connection mechanism makes the fluidic seals in an automated fashion. A plurality of sensors capable of detecting leaks is situated in the device near leak-prone regions. The electrospray emitter has a current sensing electrode in proximity of the electrospray region, capable of detecting the electrospray current. In conjunction with an electronics system, these sensors allow for system and component diagnostics. The diagnostic information may then be used for manual or automated system repair.

  • Publication number: 20110062700
    Abstract: A method for joining molecularly oriented pipe in which a coupling is provided which is formed of a material other than molecularly oriented pipe, such as ordinary PVC pipe. The coupling if formed as a tubular body with a combination sealing and restraint mechanism located in each of two opposing end openings of the coupling that seal and restrain mating plain spigot ends of the molecularly oriented pipe. Because the coupling is made of a material such as ordinary PVC, the sealing and restraint mechanisms can be installed in internal grooves provided in the coupling interior during normal pipe belling operations without introducing unacceptable levels of stress or strain into the product.

  • Publication number: 20110042935
    Abstract: A conduit/piping sump penetration fitting is disclosed. The conduit/piping sump penetration fitting may comprise a bulk head fitting which does not require a plurality of mounting holes to mount the bulk head fitting to a sump wall. Rather, the bulk head fitting has a flange and a threaded portion. Opposed sides of the sump wall may have a rubber gasket through which the threaded portion is fed. A compression flange and compression nut compress the rubber gaskets onto the sump wall so as to form a fluid tight seal between the bulk head fitting and the sump wall. The threaded portion may have an internal beveled surface at its distal end portion which receives an o-ring. A conduit/piping is disposed in the bulk head fitting with the o-ring disposed about the conduit/piping. A second compression nut is threaded onto the threaded portion of the bulk head fitting which pushes the o-ring further down the internal beveled surface.

    Abstract: The invention relates to a coupling for a fluid line, wherein an oscillating circuit (5, 9) is present for detecting a properly closed position of an inserted part (13). A tuning device (19) is further provided, by means of which the resonant frequency of the oscillating circuit (5, 9) can be influenced such that the resonant frequency corresponds to a characteristic closure frequency only in the closed position of the insertion part (13). The proper arrangement of the insertion part (13) in the closed position can thereby be detected without contact.

Each side of the flange (1) is equipped with at least one lug (3) in order to engage in a corresponding cutout (22) in the terminal end (21, 21?) of the respective tube (20, 20?), wherein the lugs (3) engaging in the cutouts (22) prevent the tubes (20, 20?) from twisting relative to one another. On each side of the flange (1) is provided a cylinder portion (5, 5?) which can be plugged into the inside of the respective tube (20, 20?). In addition, each cylinder portion (5) has an axial gap (7), resulting in flexible endpieces (9A, 9B) above and below the gap. The first flexible endpiece (9A) has a radial bore (11) with a screw element (13) for tightly clamping the tube connection (10) in the tube (20, 20?).

  • Publication number: 20100283234
    Abstract: A connection system comprises a connector and a pipe. The pipe is made from a hydrophilic membrane capable of pervaporating brackish water or such like as substantially pure water, such as Dutyion™. One feature of this material is that it expands significantly as it hydrates. The pipe is generally cylindrical, but it is corrugated along its length, with roughly regular ridges and grooves. The connector has a side wall defining a substantially cylindrical cavity. The inside surface of the cavity is corrugated in the similar way to the pipe. When the pipe is in a dehydrated state, the cavity of the connector has a maximum diameter D greater than the maximum diameter B of the pipe and a minimum diameter C less than the maximum diameter B of the pipe. The pipe can be inserted in the cavity of the connector in a dehydrated state. When the system then carries water, the pipe hydrates, which causes the pipe to expand and its diameter to increase.

  • Publication number: 20100260540
    Abstract: A tubular connector system is disclosed for joining two pipe ends. In one form, the pipe ends are joined without the necessity of rotating the pipe ends. A special coupling has opposing tapered ends. Each of the tapered ends slopes inwardly from an inner extent to an outer extent thereof to thereby form a respective mouth opening of the body. Each tapered end of the coupling has a specially contoured surface which is made up of a series of alternating helical spline wedges. The wedges are oppositely tapered from an inner extent to an outer extent thereof, whereby the helical spline wedges form an alternating series of lands and grooves on the body as viewed from the respective mouth openings. The two opposing pipe ends have mating engagement surfaces which engage and mate with the contoured surfaces of the coupling as one pipe end is pushed toward the other during assembly. In another form, the pipe ends are joined with only a slight rotation of the pipe ends.

  • Patent number: 7708317
    Abstract: A hollow pipe connector is described for interconnecting opposed ends of two hollow pipes in abutting end-to-end relationship. Preferably, but not exclusively, the pipes are hollow pile cylinders of circular cross-section. The connector is formed by two flat metal plates each having interconnecting slots whereby the plates are coupled together to form a connector of X-cross-section. Each of the plates have outer side edges having opposed sloped edge portions on a respective side of an arresting raised projection formed in the outer edge in a mid-section thereof. The sloped edge portions slope inwardly towards a respective one of the opposed ends of the connector member. The connector engages opposed end portions of pipes coupled together by a frictional retaining force exerted on the inner walls at opposed ends of the coupled pipes.
