Abstract: A coupling device (10) provides sealing members (24), (26), preferably Indium wire O-rings (72), (74), suitable for sealing engagement with an insulating member (28) under cryogenic, high-pressure conditions. Coupling device (10) is designed to couple a first metal pipe attached to a first adapter (12), and a second metal pipe attached to a second adapter (14), so that fluid may be conveyed via bore (36), chamber (84), and bore (48) under such cryogenic high-pressure conditions. According to the invention, the coupling device (10) provides effective sealing under these extreme conditions while also providing thermal and electrical insulation due to the advantageous construction featuring insulating member (28), first collar member (20) and second collar member (22).

Abstract: A large tillage implement provided with hinging wing sections is adapted for end towing rather than wing-up folding transport. The hitch which is normally centered at the front of the machine may be swung into a folded condition parallel with the longitudinal axis of the frame and overlying the front portion thereof to project the hitch coupling to the vehicle outwardly beyond the end of the frame. A front row of tillage shanks can be selectively raised or lowered as desired while leaving the rear row of shanks at their normal elevations for ground working, and a special frame design enables the rear ground wheels of the frame to be position in close fore-and-aft proximity to the rear tillage shanks to provide more uniform depth of penetration of the shanks as rises and falls in the ground terrain are encountered.

Abstract: A low tolerance joint connecting a pair of hollow refractory bricks, e.g., center riser bricks, runner bricks, etc., together for carrying molten metal, e.g., steel, therethrough. Each brick has a pair of ends with a central passageway extending therebetween. One end of one brick comprises a conical walled annular flange projecting therefrom and a shoulder extending about the annular flange. One end of the other brick comprises a matingly shaped circular recess and shoulder extending about the circular recess. The joint comprises the interface between the adjacent surfaces of the annular flange and recess when the flange is located therein. The interface thus formed is an elongated space, free of mortar or other sealing material, into which the molten metal flows to freeze therein and thereby form a seal precluding its egress from the passageway to the ambient surroundings.

Abstract: A quick-release connector for a pair of conduits has a tubular male component which has a rear portion insertable into a first conduit, a front portion, an annular external protuberance between the front and rear portions, and several equidistance axially parallel disengaging members which cross the protuberance and have projections at their front ends. A tubular female component of the connector has a rear part which is insertable into the other conduit and a front part with equidistance axially parallel resilient arms, one for each disengaging member. The arms have internal detents which can engage a radial rear flank of the protuberance when the front portion of the male component is inserted into the front part of the female component.

Abstract: A pipe coupling between the two pipes comprises a first end member at the end of the first pipe having a rearwardly facing shoulder and a sealing surface at its leading end, a second end member at the end of the second pipe having an external screw-threaded portion and a sealing surface at its leading end, and a clamping ring comprising an internal screw-threaded portion screwed onto the second end member and an inwardly directed collar butting against the shoulder of the first end member to hold the sealing end surfaces of the first and second end members in engagement with each other, the clamping ring defining a collection chamber for leakage from between the sealing surfaces and having an outlet port for draining away the collected leakage.

Abstract: The overall description of this invention is a truncated buttress-type thread form that incorporates a reverse-angle tension load flank with a compression flank and a torque shoulder; the thread does not have any radial interference designed into it, but the hooked tension flank does tend to pull the pin and box together once the torque shoulder is engaged. The mating compression flanks have designed into them a minimum amount of clearance prior to the shouldering action, which then closes to zero or very near zero at the moment the shoulder is engaged. This drawing together is due to the tendency of the hooked threads to pull together at shouldering if there exists no radial interference in the thread body. The thread roots and crests can be tapered, parallel to the taper of the thread body, or flat and parallel to the pipe axis but maintain adequate clearance to allow some closure once the shoulder is engaged so that the compression flanks can draw together.

Abstract: A sealing ring having a predetermined axis of symmetry is formed of a resiliently compressible elastomer for use in a sealing ring system in which two members are secured together with the ring interposed therebetween. The sealing ring has an annular base portion that has substantially parallel first and second axially extending surfaces with each surface having a first axial edge and a second axial edge spaced therefrom, and the second axial edges are joined by a radially extending surface. Integrally formed with the base portion is an annular head portion that extends between both of the first axial edges of the axially extending surfaces of the base portion. The head portion has a predetermined maximum axial thickness and at least one substantially planar surface extending generally radially a predetermined distance from the first axial edge of at least one of the axially extending surfaces of the base, whereby each of the planar surfaces and the adjacent axially extending surfaces form a shoulder.

Abstract: Large and small seal ring segments are interconnected to allow for circumferentially overlapping sliding engagement therebetween. The seal ring segments form an annular seal ring having a radial flange which is mounted within an annular radial groove formed in one end of a conduit. An adjoining conduit is formed with a sealing band having a spherical contour for engaging a cylindrical base portion of the seal ring with an axially slidable and pivotable fit.

Abstract: A fitting for attachment to a tube by external swaging is disclosed. The fitting includes an outer surface that fits within the dies of a swaging tool, and an inner surface that includes a plurality of axially spaced annular grooves that bite into the tube upon swaging. A reinforcing ring surrounds the outer surface of the fitting in the area of the annular grooves to provide reinforcement. The fitting also has an outer end with a special double tapered configuration such that, after swaging, the tube and inner surface of the fitting in the area of the annular grooves forms a wedge that equally distributes the load and increases the tube retention capability of the fitting. The fitting also includes a tapered shoulder for positioning the fitting within the dies of the swaging tool in a reliable and repeatable manner, and further includes tapered axial grooves on the inner surface of the fitting for preventing torsional movement between the fitting and the tube after swaging.
