  • Patent number: 8333295
    Abstract: The invention in one variation is a pressure vessel having a pair of hemispheres with a wall and a circular edge, a pair of sealing elements, and an intervening mounting plate with circular groove on both sides of the plate. The hemispheres are mounted on opposite sides of the plate. Each groove has an sealing element and the circular edge. A seal is formed between the plate and a hemisphere when the hemisphere is pressed against the sealing element. Pressure can be generated by creating a partial vacuum in the sealed hemispheres or by using clamps. When exposed to higher pressures, such as when the vessel is used underwater, the pressure on the hemispheres is conveyed to the sealing element forming an even tighter seal. The vessel has interface connections that enable communication to and from devices mounted inside. The vessels are modular and can be ganged to provide redundancy or different functions.

    Abstract: A pressure vessel for reducing air entrapment bubbles inherent in lost pattern type casting mould compounds and for increasing the density of the mould material, which in turn has proven to provide a smoother finished surface to the cast material. The pressure vessel consists of separable upper and lower halves held together under loading with an eccentric cam system. The eccentric cam has an overcenter position which causes a greater closing force to be applied to the pressure vessel as pressure is increased within the chamber. Integral to the closing cam is a separate locking cam which operates in unison with the eccentric cam to prevent the eccentric cam's positioning lever arm from being moved while the chamber of the pressure vessel is pressurized.
