Abstract: A gas-insulated transmission line includes a cylindrical outer sheath, an inner conductor within the outer sheath, an insulating gas, and support insulators for insulatably supporting the inner conductor within the outer sheath. The support insulators have a pair of circumferentially spaced apart openings therein, and a wheel assembly is disposed within each of the support insulator openings. Each wheel assembly includes a rotatable wheel which extends outwardly of the support insulator opening and contacts the outer sheath. With such an arrangement, insertion or movement of the inner conductor within the outer sheath is done on wheels instead of with a sliding motion to thereby minimize the generation of conducting contamination particles.

Abstract: A flexible pipe includes an elastic pipe body in corrugated form and including alternate large and small radius portions. A ring is mounted within one of the large diameter portions of the interior of the pipe body. An elongated flexible and deformable shaping member is secured to the ring and extends throughout the interior length of the tube body.

Abstract: In a hot gas duct wherein it is desirable to retain heat within the duct by insulated sidewalls and wherein the duct is substantially longer than it is wide, it is necessary to support the duct against excessive deformation in the lateral direction. Exterior support structures are unacceptable because locating cross members or struts becomes problematic. Interior support structures must be carefully designed so as not to inhibit thermal expansion and contraction within the duct. It is proposed that a lateral bracing system or truss be disposed entirely inside the hot gas path and provision be made to ensure adequate facility for uniform expansion of the truss within the hot gas duct.

Abstract: A cable structure comprising a cable provided with a cable sheath in the form of a flexible corrugated or undulated tube. Between the cable and the sheath there are arranged guide bodies at predetermined locations. The guide bodies are fixed at the inside of the sheath and are provided with domed or arched guide surfaces at the side of the cable, in order to guide the cable both in a straight and bent condition.

Abstract: An insulated conduit composed of an inner structural tubing with each length or bend of said tubing having a bell socket at one end with a matching spigot joint at the other end, and so arranged that one is enabled to assemble comparitively long continuous lengths of the insulated conduit. Resting blocks are placed at appropriate position and distances within the inner structural tubing whereby energy carrying piping may be inserted within the inner structural tubing and rest upon said blocks. The energy carrying piping is protected from loss of heat energy by the insulative value of the ambient air within the inner structural tubing and also by the inclusion of inert air spaces located between a series of structural ribs which form a support between the inner structural tubing and an outer insulation jacket.

Abstract: A foam extrusion apparatus and method employs an extruder on an upper level extruding foamable extrudate into the upper end of a large elongated barometric leg which extends at a relatively shallow angle into a pool of water at a lower level. A conveyor in the barometric leg extends through a large radius in the pool to guide the extrudate from the pool for further processing. The leg is in the form of an elongated pipeline fabricated from sections and supported on an inclined ramp. Some of the sections are securely anchored to the ramp to resist axial forces when the leg is evacuated. The sections may be reinforced concrete or fabricated reinforced steel of a variety of sectional shapes. Each section is sealed end-to-end so that a vacuum within the leg will draw water from the pool into the leg leaving a vacuum chamber at the upper end of the leg in which the extrudate expands.

Abstract: A spirally configured member, rotatably positioned within an elongated tube, the spiral member adapted to continuously clean the tube's interior wall when such member is caused to rotate. The spiral has one end rotatably anchored by a plug fixed to one upstream end of the tube and a swivel linking the plug and the spiral member.

Abstract: A support arrangement is used for elastically mounting a monolithic ceramic honeycomb structure within a housing in an exhaust gas pipe and consists of a holding angle and a molded part formed of a soft, flexible material. The holding angle is rigidly secured to the inner surface of the housing with one of its legs extending along the wall of the housing and the other extending radially inwardly from the inner housing surface. The molded part is rigidly secured to the inner end of the other leg of the holding angle and extends from its point of rigid securement in generally the same direction as but spaced inwardly from the one leg of the holding angle. At its end opposite the end secured to the holding angle, the molded part is bent radially outwardly into sliding contact with the inwardly facing surface of the holding angle. The combination of the holding angle and molded part form a cavity which may be filled with a heat-resistant material.

The shell includes first and second circumferential portions of an equal diameter which are at opposite axial ends thereof, and a third circumferential portion located therebetween and which has a greater outer diameter than the first and second portions. Thus bevelled areas are defined between the first and the third and between the second and the third circumferential portions. The converter is rigidly mounted in a gas passage defined by a pair of tubular members which are connected in tandem with an internal combustion engine. One of the tubular members has an inwardly extending annular rib at a given distance from the end thereof.

Abstract: A tubular element having structural members disposed thereon at selected axial locations for supporting thermocouples inside the bore of a hollow shaft. Each of the structural members constitutes a generally "X"-shaped configuration which is substantially divided in half to form separated sections. Thermocouples placed in the legs of each X-shaped structural member are biased into contact with the shaft's interior surface by spring members which are disposed in openings formed in both sections on opposite sides of the X member's division at low or zero speed and by the springs and centrifugal force at high speed. Relative axial movement of the sections constituting each X member is restrained by dowels set into the sections and across the space separating them. Wires from the thermocouples extend radially into and axially within the tubular member. At one axial end of the tubular member the thermocouple wires are connected to a rotatable transmitter which broadcasts signals received from those thermocouples.

Abstract: A support which can be assembled and disassembled at room temperature and events translational and rotational motion at temperatures below room temperature. A truncated cone is located between an outer support housing and an inner housing which is to be supported. The narrow end of the cone is sized to fit over the inner housing and the wide end of the cone is sized to fit within the outer support housing. The cone is comprised of a material which has a higher thermal expansion coefficient than the inner housing.

Abstract: The invention provides an assembly for accommodating service lines which comprises a length of ducting, a block of structural cellular material which fills the internal cross section of the ducting over at least a part of the length of the ducting, said block having cell walls which define cells which extend in the length direction of the ducting and on the cell walls a coating of intumescent material expandable to close the cells under fire conditions. With the block positioned where the ducting passes through a fire-resistant wall, the spread of fire through the ducting is usefully opposed. Using thermoplastic ducting, which has heretofore been contra-indicated, results superior to those obtainable with steel ducting are achieved.

Abstract: The invention concerns the centering and the fixing of a long thin object inside a tubular body. It has as its object a means consisting in a filling in of the space left free by the long thin object inside the tubular body with a granular substance at least a part of which is agglomerated by means of a resinous isocure compound hardening when cold in a very short time on coming into contact with a gaseous catalyst. It applies more particularly to the centering of a wave guide in a metallic tube.
