Abstract:
A mounting structure is provided which is particularly adapted for holding a level sensor in place at an opening on vessels containing pressure above or below the ambient pressure. First and second fitting members are provided which are installed on the vessel at the opening provided thereon. The level sensor is releasably attached to the second fitting member positioned on the exterior of the vessel so it is in communication with the interior of the vessel. The first and second fitting members are mechanically locked together so that the vessel wall is held captive between the fitting members. The mounting structure provides a positive mechanical lock between the vessel and the level sensor ensuring that the level sensor will not be blown out of, or sucked into, the vessel even if the fluid tight seal between the mounting structures fails.
Abstract:
A dual-chamber composite pressure vessel includes a first enclosure formed of a fiber reinforced resin matrix, having a hollow cylindrical central section, and first and second oblate end sections formed integrally over respective ends of the central section to define a first chamber. Also included is a second enclosure formed of a fiber-reinforced resin matrix, integrally with the first enclosure, and having a second hollow cylindrical section which is joined at one end to and extends from the second end section co-cylindrically with the central section of the first enclosure. The second enclosure also includes a third oblate end section formed integrally over the other end of the second cylindrical section to define a second chamber.

Abstract:
A vacuum press adapted for laminating transparent protective film to photographs and the like and for dry-mounting the same to suitable substrates or backing materials. The press comprises a base characterized by a flexible air-impermeable wall which supports the work sheets and a cover assembly hinged to the base. The cover assembly includes a platen which when brought into engagement with the base cooperates with the flexible wall to form a reducible work-receiving chamber. Means are provided for heating the platen and indirectly the work and for evacuating the work-receiving chamber to cause the work to be laminated under heat and pressure.
