Abstract:
One embodiment of the present coupler comprises two or more conduits for transporting fluid. Each of the two or more conduits has at least one end defining an opening in said conduit, and each of the conduits has an axis running parallel to the flow of fluid through said conduit. The coupler further comprises a housing body having a first housing planar surface. The housing body holds the two or more conduits in alignment wherein the axis of each conduit is substantially parallel, and at least one end of each conduit is aligned about said first housing planar surface. And, the coupler has a cap element having a cap planar surface. The cap planar surface is fixed to the first housing planar surface in sealed engagement. At least one of the first housing planar surface and the cap planar surface has a channel in fluid communication with the opening in the conduits. The channel allows two or more fluid streams, each fluid stream defined by one of said conduits, to be placed in communication.
Abstract:
A laboratory joint is provided for a pair of male and female members having matable tapered ends which are connected together by a sleeve which can lock the members together to prevent accidental separation, which sleeve is capable of separating the assembled members when desired in a safe and expedient manner.
Abstract:
A coupling is provided to hold together a cone and socket joint between items of laboratory glassware. A first annular member is positioned about the cone portion of the joint and has a male threaded end. A second annular member is positioned about the socket portion of the joint and has a female threaded end which may be screwed onto the male threaded end of the first annular member. The first annular member has a seat which engages with an elastomeric sealing ring so that as the first and second annular members are tightened together the elastomeric sealing ring is compressed into the external line of junction corresponding to the outermost circumference of contact between the cone portion and the socket portion of the assembled joint. The second annular member locates indirectly behind the external strengthening lip around the mouth of the socket portion by means of an interjacent ring which has a male frustoconical surface. The second annular member has an inwardly directed flange formed with a female frustoconical surface which cooperates with the male surface of the interjacent ring whereby, in the assembled coupling, the axis of the assembled coupling is aligned with the axis of the cone and socket joint and the interjacent ring is urged radially inwards behind the socket portion of the joint.
Abstract:
A fluidic coupling device includes a housing, and a piston, spring, and cap insertable in the housing. The spring includes a stack of spring washers and is compressible between the cap and the the piston. The cap is threadedly engageable with the housing and movable into contact with the spring. The device may be coupled to a component in a sealed manner by inserting a ferrule between the piston and the component, inserting a conduit through the housing and into the component, and threadedly engaging the housing with the component, thereby compressing the spring and translating the piston against the ferrule. The device may enable coupling to be done manually, with minimal variation in compressive loading. The piston and spring may desensitize the device to thermal cycling effects, reducing the need for retightening.
Abstract:
A closure fitting for enclosing a portion of one or more carrier conduits between a first containment conduit section and an opposed second containment conduit section has: (a) a first cylindrical hollow body; (b) a second cylindrical hollow body, the second body being reversibly attached in fluid tight communication to the first body; (c) a first seal for sealing the first body to the first containment conduit section and a second seal for sealing the second body to the second containment conduit section, wherein and (d) a third seal for reversibly sealing the first body to the second body. In the invention, at least one of the first or second seals allows one of the bodies to axially move with respect to its containment conduit section.
Abstract:
A fitting element is configured for coupling tubing to a fluidic device having a receiving cavity configured for receiving the fitting element, where the tubing has an inner contact surface of a biocompatible material, the inner contact surface being configured to contact a fluid to be conducted by the tubing, and the receiving cavity having a receiving contact surface of a bio-compatible material. The fitting element includes a first sealing element of a bio-compatible material configured for sealing to the bio-compatible material of the inner contact surface of the tubing, and a second sealing element configured for sealing against a pressure ambient to a pressure of the fluid in the tubing. Upon coupling of the tubing to the fluidic device, at least a portion of the receiving contact surface, the first sealing element, and the second sealing element enclose an interspace, each surface of the interspace being a bio-compatible material.
Abstract:
A combustor assembly includes a metal section having an axial slot that receives a ceramic section. A clamp is received about the axial slot to secure the metal section and ceramic section together. Tabs on the metal section, a gasket between the metal section and the ceramic section, and springs within the clamp deform an amount that is greater than a thermal expansion difference between the metal section and the ceramic section to maintain a clamping force of the clamp.
Abstract:
Provided is a process for producing a glass-like carbon deformed molded article having a deformed section (typically, an elliptical section or a section composed of partial circles and linear portions), such as a glass-like carbon member in a deformed pipe form or a bent pipe, with relative ease and a good dimensional accuracy. The process comprises the step of molding a thermosetting resin to yield a thermosetting resin molded article, the step of deforming the thermosetting resin molded article plastically in the state that the article is heated, so as to yield a thermosetting resin deformed article, and the step of carbonizing the resultant thermosetting resin deformed article.
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.
