Abstract: A delivery container for temperature sensitive goods is provided having sidewalls, a rear wall, top and bottom walls all of a heat insulated construction, an upright access opening opposite the rear wall and a door assembly for selectively closing the access opening. Multiple generally upright cavities are associated with the sidewalls and rear wall. A cooling gas distribution arrangement includes a refrigerant receiving recess (12) provided in a refrigerant support tray having surfaces (15) inclined downwardly towards an upper region of the sidewalls and rear wall for distributing cooling gases generated by refrigerant located in the refrigerant receiving recess (12) to openings communicating with the multiple upright cavities, in use. The door assembly preferably includes an uppermost panel (35) that opens separately from the balance (36, 37, 38) of the door to provide access to the refrigerant receiving recess (12) for installing or removing refrigerant whilst the rest of the door assembly remains closed.

Abstract: The invention provides a faster, safer, more reliable and cost-effective method to permanently or temporarily repair leaking in-service pipes than welding and other devices and methods currently used to repair leaking pipes. The interlocking pipe clamp and internal circumferential self-pressurizing seal, installed in a recessed seal groove within the clamp housing, embodies a unidirectional fluid orifice leading to an internal pressure responsive chamber whereby trapped fluids inside the chamber expand outwardly under pressure to force the external sealing surface of several pliable, multi-combed and conjoined fingers to form a series of redundant seals against the leaking pipe with increasingly greater force to prevent the escape of fluids from the pipe and to prevent seal dislodgement from the pipe repair clamp. The seal material is composed of resilient synthetic and natural materials which are corrosion and fire resistant and color coded for specific fluid repair applications.

Abstract: This self-pressurizing seal invention embodies resilient, non-corrosive and fire resistant construction with an internal pressure responsive chamber whereby fluids entering such chamber through a unidirectional fluid orifice are trapped in the internal chamber and whereby the resulting pressure differential causes outward expansion from the internal chamber to external sealing surface of multiple, pliable and conjoined ridges to form a series of redundant circumferential seals against the axial pipe surface with corresponding force to prevent the outward flow of fluids from the pipe juncture in a pipe coupling or valve.

Abstract: This invention relates to pipe coupling with multi-combed, self-pressurizing internal seals and an integral pipe fastening system to join and seal pipes of all sizes, fluid contents and line pressures. The invention embodies a coupling body, two pressure responsive seals installed in recessed seal grooves located at opposite outside edges of the pipe coupling body, and seal body consisting of a unidirectional fluid inlet and internal pressure responsive chamber and an external sealing surface comprised of several resilient, multi-combed and conjoined lips and fluid pockets which form a series of redundant seals around the outside axial surface of pipes joined within the coupling. Fluid escaping from the pipe juncture enters the internal pressure responsive chamber through the unidirectional orifice wherein trapped fluids expand the pliable external multi-combed seal surface against the axial surface of each pipe with corresponding force to prevent the outward flow of fluid from the pipe coupling.
