    Abstract: A method and apparatus for sealing the drive end of a chamber for the preparation and hydrogenation of coal with hydrogen to form hydrocarbons in which the chamber comprises a hollow cylinder with a rotatable element therein having a conveying web thereon and in a sealing region a pressurized sealing substance such as coal particles mixed with oil is fed from a storage container through a feed passage into an annular recess at a pressure higher than that in the chamber so that the sealing substance passes through a conical annular gap which tapers towards the chamber. A further narrower gap on the drive side of the recess leads to a further annular recess from which the sealing substance can be extracted through a return pipe. Pressure comparison means control the feed pressure in the feed passage. The recesses and the annular gap can be provided by machining the rotatable element rather than the hollow cylinder and forward feed screw forms may be provided on the rotatable element in the sealing region.

    Abstract: In a rotary vacuum sealed wafer transport system for transporting semiconductive wafers between ambient atmosphere and subatmospheric pressure within a wafer processing station, the wafers, on a conveyor web pass through a slot in the vacuum chamber of the processing station. The evacuable envelope of the processing station has an external concave face portion intersecting with a generally planar face portion with the slot being positioned generally at the intersection of the concave and planar face portions. A deformable elastic roller, preferably pneumatically inflated, is disposed for rolling sealing engagement with the conveyor web and wafer and for wiping sealing engagement with portions of the planar and concave faces to provide a gas tight seal of the slot while permitting passage of the conveyor web with the wafers thereon into the evacuated wafer processing station. In a preferred embodiment, the conveyor web passes through input and output slots with pneumatic rollers sealing the pair of slots. In the latter case, the rollers are preferably driven in unison to prevent any wiping action of the roller on the surface of the wafer. In an alternative embodiment, the conveyor web is omitted.

    Abstract: Disclosed is a safety closure apparatus for a pressure vessel, particularly for a vessel such as a pump stabilizer which has a gas compartment and a liquid compartment therein, both of which are normally pressurized. The apparatus includes a safety head configured to cover the closure means of the vessel to prevent its actuation; a liquid pressure bleed valve which must be removed before the safety hood can be moved off of the closure means, thereby insuring depressurization of the liquid compartment prior to opening; and gas pressure bleed means automatically operable upon movement of the safety hood off of the closure means, thereby also insuring depressurization of the gas compartment before access can be had to the closure means to actuate it to open the vessel.

    Abstract: A fluid container, such as a pressure vessel, in which a removable closure plug is adapted to sealingly close an open end of a cylindrical vessel. The closure plug is supported relative to the vessel in a manner so that a space is defined between respective surface portions thereof, with a sealing member being disposed in the space. Heat is applied to the vessel to cause movement thereof relative to the closure plug and a compression of said sealing member prior to the final attachment of the closure plug to the vessel.

    Abstract: An access door for a pressure vessel wherein the door itself is the only moving part and the pressure difference between the interior of the chamber and ambient exterior pressure is the only sealing force is provided. The door is in the form of a disc or wafer made of metal or solid plastic material and holds in position a sealing ring having a peripheral groove for receiving one O ring and a groove on the surface facing the door for receiving a second O ring. The door is rolled manually by a substantially radially extending handle. The chamber is cut to receive the door laterally and recessed internally to permit the sealing ring to be moved axially into sealing position in the recess.

    Abstract: A sealing door for heat-treating furnaces having a piston and cylinder arrangement that not only raises and lowers the door but also moves the door outwardly slightly upon opening to protect the door seal during the vertical movement of the door and also presses the door against the furnace upon closure to seal the furnace against leakage of internal vacuum or pressure.
