  • Patent number: 7637289
    Abstract: A sectional heat insulation jacket comprises a set of multi-layer insulation sections in which the layers are bound together by a fastening and fixing device. Adjacent insulation sections connect and they separate by assembling joints that are self-sealing. A mutual position of the adjacent sections is reliably fixed by the connecting device at each stage of heating. The self-sealing is accomplished by side flexible layers which incline under a sharp angle to the surface of an upper flexible layer. The sizes of the assembling joints between adjacent sections at levels of the upper and the bottom flexible layers are equal to the temperature expansions of these layers in longitudinal and transverse directions, correspondingly under the insulated entity's heating until an operating temperature is reached. A conical, helical spring shaped fastening rod further increases a length of metallic inclusions with high thermal conductivity form an insulated entity and reduces heat loss.

  • Patent number: 4635409
    Abstract: The present invention provides a pitch pan with just two J-shaped sections. The long leg of one J-shaped section is aligned with the short leg of the other J-shaped section, and vice versa; and the legs of the two J-shaped sections are provided with positioning surfaces which permit the long and short legs of the J-shaped sections to be shifted relative to each other to define adjustable-length walls at opposite sides of a filler-receiving recess. That two-section pitch pan is covered with water-impervious skirting before it is delivered to the job site. All an installer need do is to align the two sections of that pitch pan, secure them to each other and to the roof with fasteners, use a cement or adhesive to seal the skirting of those sections to the roof, use a cement or adhesive to seal an overskirt in position at each of the two sides of the pitch pan where the skirtings of the two sections confront each other, and then fill the filler-receiving recess defined by that pitch pan.

  • Patent number: 4606080
    Abstract: A sanitary, portable toilet comprised of a barrel-shaped stool formed of split cylinders which are detachably mounted at their top ends by an annular seat and at their bottom ends by a pair of C-shaped baseplate elements. The elements of the baseplate are detachably mounted together through pin and shackle connections. A flexible disposable liner is suspended within the stool with the upper end of the liner captured between an outer rim at the upper end of the split cylinders and a downwardly extending rim of the seat. A lid is pivotally mounted on the top of the seat.

  • Patent number: 4545701
    Abstract: Arcuate concrete segments of a tunnel wall are joined together in the peripheral direction by abutting steel castings embedded and anchored in the segment ends, and nut and bolt assemblies interconnecting the castings. Longitudinally adjacent segments are joined together by arcuate openings through the segments, nesting positioning members at the interface between the segments, and arcuate nut and bolt assemblies extending through the openings and positioning members.

  • Patent number: 4438785
    Abstract: An insulated pipe enclosure for use above ground includes opposed, internally insulated, generally C-shaped, thin-walled base and cover sections, which are interconnected end-to-end by overlapping one section with the next, each cover and base being interconnected by screws in flanges extending outwardly from each side of the cover and base. The pipes in the enclosure rest on vertically extending supports, which are embedded in the insulation of the base sections.

  • Patent number: 4411134
    Abstract: A replacement transition duct assembly for a jet engine comprised of a plurality of complementary louvered sections having joining ends that are assembled together about the engine by means of a novel bracket. The bracket is formed with a spaced array of louvered segments adapted to interfit with and receive the joining ends of the replacement duct sections, and includes an offset element to which the joining ends are secured. When the joining ends are secured to the bracket, the bracket provides an effective seal between the replacement duct sections, presents a minimum impediment to the flow of exhaust gases, and completes the integral formation of the replacement transition duct assembly.

  • Patent number: 4280536
    Abstract: A connector is used to join sheets of fibrous insulation into a duct. The connector includes a base plate to which a plurality of guide flanges and penetrating flanges are connected. The penetrating flanges are spaced from and parallel to the guide flanges, and both the penetrating and guide flanges project from the base plate. In use, the guide flanges bear against the outer surface of the insulating sheet while the knife-like edges of the penetrating flanges penetrate and mesh with the longitudinal fibers of the insulation.

  • Patent number: 4052999
    Abstract: Operation of a plasma device such as a reactor for controlled thermonuclear fusion is facilitated by an improved bumper wall enclosing the plasma to smooth the flow of energy from the plasma as the energy impinges upon the bumper wall. The bumper wall is flexible to withstand unequal and severe thermal shocks and it is readily replaced at less expense than the cost of replacing structural material in the first wall and blanket that surround it.

  • Patent number: 4023374
    Abstract: A preformed molded fiberglass reinforced plastic repair sleeve for use on a marine or other submerged concrete pile and a method of applying the same. The sleeve is provided with at least one vertical seam consisting of inside interlocking reentrant bends which together establish an interlocking tongue and groove joint. The joint is maintained effective by self-tapping screws which are in engaged relation with steel closure clips or strips. The sleeve after assembly is centered about the pile undergoing repair and the continuous space which exists between the sleeve and the pile is filled with a suitable grout which, when hardened, encompasses the internal or inside portions of the joint under pressure and prevents unfastening of the seam.
