Abstract:
Fluid connector for connecting a first fluid-bearing conduit in a capillary tube to a second fluid-bearing conduit in a receiver. An internal fitting assembly includes an internal fitting body, a body cavity for receiving a ferrule and a self-compensating nut, the ferrule and self-compensating nut being locatable on the capillary tube, and an internal ferrule seat located on a portion of the body cavity, against which a tapered portion of the ferrule is applied to so as to obtain a first fluid-tight seal between the capillary tube, the ferrule, and the ferrule seat. The forward end of the internal fitting body includes a nose cone, having thereon an annular projection, a neck portion which connects the nose cone to the remainder of the internal fitting body, and an annular seal located on the neck portion, wherein the annular projection defines a first frustoconical segment and the annular seal includes a second frustoconical segment, the first and second frustoconical segments being configured to establish a second fluid-tight seal at the receiver port surface as the forward end of the internal fitting body is coaxially aligned with the receiver port and thrust into the receiver cavity.
Abstract:
A dual containment fitting may include a primary tubing, a secondary tubing, and a dual containment body. The secondary tubing may surround and be concentric with a first portion of the primary tubing forming a first leak containment space between the primary tubing and the secondary tubing. The dual containment body may include a flare fitting portion and a primary containment nut portion. The flare fitting portion may surround and be concentric with the primary tubing forming a second leak containment space between the primary tubing and the flare fitting portion. The primary containment nut portion may surround and be concentric with the flared end of the primary tubing forming a third leak containment space between the primary tubing and the primary containment nut portion. The primary containment nut portion may include at least one leak passage hole connecting the third leak containment space with the second leak containment space.
Abstract:
A fitting assembly having a double-headed ferrule, a nut, and a fitting that may be assemble or dissembled by an operator. The fitting assembly includes a nut with first and second ends, with the second end have an internally tapered portion adapted to receive the first end of a ferrule, and further includes a fitting with a first end having an internally tapered portion adapted to receive the second end of the ferrule and a second end adapted to be removably connected to a component or fitting of a liquid chromatography system. The nut, ferrule and fitting of the fitting assembly have passageways therethrough for receiving and removably holding tubing.
Abstract:
Disclosed is a terminal adapter device to enable an IEEE1394-to-Ethernet conversion for processing by hardware data of an Ethernet standard that is inputted/outputted in a home network system based on an IEEE 1394. The terminal adapter device includes a 1394 unit to perform an IEEE 1394 connection with a home gateway unit, connected to a network such as a Wide Area Network (WAN), to process data of the network system, and with an external IEEE 1394 client, an Ethernet unit to perform an Ethernet connection with an external Ethernet client, an Ethernet/1394 conversion unit, connected to the 1394 unit and the Ethernet unit, to perform a protocol conversion, and a control unit to control the protocol conversion.
Abstract:
A ramp-lock quick-connect fitting is adapted to be placed between conventional type fittings on pipes and tubes, such as quartz pipes and synthetic resin tubes used in chemical processing systems for semiconductor device fabrication. The quick-connect fitting includes a first coupling member having a pipe receiving section adapted to receive a conventional fitting on a pipe, and a ramp support section with a pair of spiral ramps formed therearound. The quick-connect fitting also includes a second coupling member that sealingly engages the first coupling member. An extension portion of the second coupling member is adapted to receive a conventional fitting on a tube. A locking collar is movably engaged with the second coupling member and has a pair of lock members disposed on an interior surface of the collar that slidably engage with the spiral ramps when the collar is rotated around the ramp support section of the first coupling member.
Abstract:
A connector for tapered glass joints includes a first glass tubing section having a tapered sealing surface on an inner end surface thereof and threads on an outer surface of said end. A second glass tubing section has an end adapted to be telescoped into the end of said first tubing section, and a replaceable, resilient sealing sleeve is adapted to be sealingly engaged concentrically between the outer end surface of the second tubing section and the inner end surface of the first tubing section. A threaded cap is adapted to be threaded onto said threads of said first tubing section to secure the parts together and to force the sealing sleeve into tight sealing engagement with the respective tubing surfaces. A retaining ring may be carried by said second tubing section for cooperation with said cap to prevent relative axial displacement between said tubing sections when the cap is tightened, and also to enable said cap to be used as a jack against said ring to separate said tubing sections when the cap is unscrewed. In another form of the invention, a split cap and clamping ring are used for larger tubing.
Abstract:
A coupling between first and second tubular members comprising a flexible retaining ring fitted over the first tubular member below an annular enlargement thereof and entering into screw-threaded engagement with internal screw-threading on the second tubular member or a connector element attached thereto. The retaining ring is a split-ring member whose longitudinally extending slit enables it to be passed lengthwise over the first tubular member and is so dimensioned that on re-assuming its original form, the opposed margins of the slit abut and the retaining ring is held against the first tubular member against removal therefrom by the enlargement, and the second tubular member or connecting member is coupled to the first tubular member. A sealing member is positioned at the coupling to form a fluid-tight seal at the junction of the tubular members.
