Abstract:
A reactor vessel liner system includes a liner having an inner wall, an outer wall, and a plurality of passages extending between the inner wall and the outer wall. An attachment member extends outwards from the outer wall for securing the liner.
Abstract:
A closure includes a hub having a bore in fluid communication with the port of a vessel. A door is removably positioned within the bore of the hub, and a locking ring is threaded with the hub thread for moving the door to a closed and circumferentially sealed position against the shoulder. At least one rotatable actuator element, such as a plurality of gears, engages the locking ring and is rotated to rotate the locking ring. A breaker bar or impact wrench could be used to rotatable drive the actuator elements.
Abstract:
A work-piece deflection management system including: (a) a first and a second vacuum chambers, each said vacuum chamber having an air-bearing seal circumscribing one of its sides, and (b) a work-piece plate; wherein the air-bearing seals are aligned to face one-another with the work-piece plate respectively there-between, allowing the work-piece to be laterally slid with respect to the air-bearing seals while maintaining a first predefined vacuum level within the first vacuum chamber and maintaining a second predefined vacuum level within the second vacuum chamber.
Abstract:
A door closure system for a vacuum sterilization chamber includes a mechanism to allow movement of the door with respect to the chamber at the hinge. An elongated slot on the door captures a fixed shaft to allow rotation of the door. A spring in the door operates against the shaft biasing the door toward the chamber. Forces applied by the hinge and by an opposite latch are normalized.
Abstract:
A modular reactor system comprises a backplane connected to a computer and a thermal control unit. The backplane includes a plurality of seats for releasably holding a plurality of modules. Each module holds a reactor vessel that may be used to conduct experiments. A plurality of laboratory instruments, such as motors, switches, sensors and pumps are included within the backplane and on the reactor modules. These laboratory instruments are utilized to perform work on the contents of the reactor vessels when the modules holding the reactor vessels are positioned in the backplane. A computer is connected to the backplane and controls the laboratory instruments within the backplane and on the reactor modules positioned within the backplane. A thermal control unit provides a thermal control fluid that is delivered to the reactors in the reactor modules when the modules are properly seated in the backplane.
Abstract:
A method and apparatus for separating volatile from nonvolatile substances, separation of volatile substances, one from the other, and for performing various chemical reactions. In particular, an apparatus which performs these functions utilizing a combination of above ambient temperatures and above one inch of mercury vacuum within a rotating vessel. The apparatus uses a conventional rotary vacuum seal. The apparatus, however, operates well above the maximum operating temperature of the conventional rotary vacuum seal by isolating and cooling the conventional rotary vacuum seal.
Abstract:
A sealing structure for an airtight chamber includes a first division member and a second division member being repeatedly joined and disjoined. The first and second chamber members are joined together to define the chamber between them and disjoined to allow access to the chamber. The structure also includes a sealing member pressed between the first and second division members to keep the chamber airtight against a pressure difference between the exterior and the interior of the chamber while the first and second division members are joined. The first and second division members are made of a material with hardness lower than that of the sealing member and are formed with a groove. The structure also includes seat members being embedded in the grooves and pressed against the sealing member while the first and second division members are joined. The seat member is made of a material harder than the division member and welded in said groove only along its contacting surfaces with the groove.
Abstract:
A vacuum sealing structure (1) for connecting a first connection part (13) with a second connection part (43) via a gasket (31). The first connection part (13) or the second connection part (43) is provided with a jaw (43a), having an end portion which is broadened outwardly of a pipe member forming a vacuum passage, and a support member (21) having an annular tapered groove (21a). The second connection part (43a) directly contacts the gasket (31) and a tapered groove (21a). Thus the second connection part tapered jaw (43a) is tightly pressed against the gasket (31) by fastening the support member (21) with a fastening member (15), thereby achieving a vacuum sealing structure for facilitating the sealing of a body (2) to be vacuum sealed. The body may be a viewing port (41). Since it is not necessary to secure the body (2) to a flange (21), welding for securing will not be required and no trouble will be caused with sealing. In the event that the body (2) is damaged, all that is required is to replace the body itself, enabling easy maintenance.
Abstract:
A receptacle terminal is provided at a mount table and comprised of a downwardly opened electroconductive cap member. The receptacle terminal is connected to a heating element of a heater. A plug terminal is forced into the receptacle terminal and has an electroconductive section, support section and insulating pipe. The insulating pipe is provided around the circumference of the support section. A first clearance is defined between the support section and the inner wall of the insulating pipe. A second clearance is defined between the end face of the electroconductor section and that of the insulating pipe. The lower end portions of the support section and insulating pipe extend out of a processing chamber via a hole in the bottom plate of the processing chamber. A gas supply attachment is provided around the circumference of the insulating pipe and has a cavity including the circumferential portion of the insulating pipe and communicating with a gas supply pipe. The cavity communicates with the first clearance via a hole partially provided in the insulating pipe at the cavity. The gas supply pipe communicating with the cavity is connected to an inert gas supply source. The inert gas is supplied from an inert gas supply source to a region near a contacting area of the receptacle terminal and plug terminal past the cavity, first clearance and second clearance.
Abstract:
A device for high-pressure treatment, in particular of liquid substances which contain components with a consistency different from that of the liquid. The device comprises a cylinder member (1), two end members (2, 3), a high-pressure piston (4), two high-pressure seals (8, 9) and connection means comprising channels and valve members to conduct the substance to and from the cylinder member (1). When the substance is pressurized, the cylinder member (1), at least one of the end members (3), the high-pressure piston (4) and the two high-pressure seals (8, 9) delimit a high-pressure chamber (10). The connection means are arranged outside the high-pressure chamber and preferably in respective end members (2, 3).
