Abstract: The invention provides an improved method and apparatus for feeding solids to a fluidized bed reactor. A back pressure control valve regulates the pressure drop between the pressure above a solids column in a standpipe and the pressure in the reactor. Solids are fed from the standpipe via a conduit without valve means, the conduit contains a bend of an angle greater than the angle of repose of the solids.

Abstract: A liquid vaporizer-feeder has a unitary housing structure for both a control valve for controlling the amount of a liquid passing therethrough and a vaporization valve for causing the liquid from the control valve to be vaporized and transported out by a carrier gas. The housing structure has a throughhole through which the two valves are connected. The throughhole is short and narrow, and has a portion made even narrower such that the pressure in the liquid passing therethrough is increased, preventing bubbles from forming in the throughhole. As a result, vaporized liquid can be supplied at a steadier rate, for example, to a reaction chamber.

Abstract: A method and apparatus for discharging hydrogen from a vacuum vessel using a roughing vacuum pump and a turbo-molecular pump. During discharge of hydrogen from the vacuum vessel, a material which has excellent reactivity with hydrogen, such as a material which has been excited or ionized by microwave or laser radiation, is introduced into the exhaust system. The material reacts with hydrogen to convert hydrogen into another substance of large molecular weight, whereby the evacuating performance of the vacuum exhaust system is improved with respect to discharging of hydrogen.

Abstract: A pressure sealed chamber such as a load lock for a apparatus for processing substrates is operated with a guide plate spaced from a substrate supported therein so as to form a gap which covers the substrate surface to be protected from contamination by moisture condensing in the chamber during the rapid evacuation thereof. During the evacuation of the chamber, by either pumping or venting, clean dry gas is introduced through an orifice in the center of the plate so as to flow outwardly from the edge of the gap at a pressure sufficient to displace or otherwise prevent gas borne moisture condensate in the chamber from entering the gap and contaminating the surface to be protected of the substrate. During the evacuation of the chamber, gas is introduced through the gap at a flow rate less that of the evacuating gas.

Abstract: A pressure equalizing liquid addition funnel for a closed system reactor is described. The funnel includes an internal valve stem which seats in the outlet port and extends therethrough and which defines a lumen which extends axially from below the outlet port upwardly to a port in the valve stem in the upper portion of said flask. The valve stem then terminates in a valve cap which is threadedly mounted on the funnel whereby rotation of the cap will cause the valve to engage or disengage a valve seat at the outlet.

The gas processing apparatus includes a manifold for introduction of a plurality of gases into a gas processing system. The manifold comprises a plurality of channels through which gas may flow toward the gas processing system, and a mixing chamber having an inlet in communication with the plurality of channels and an outlet in communication with the gas processing system. At least one of the channels has a rapidly operable feed valve at the terminus of the channel at which it communicates with the chamber inlet. The mixing chamber has a void volume that is small relative to the working volume of the gas processing system. The catalytic reactor comprises any of several novel combinations of catalytic reaction chamber and constructions providing for transfer of heat to the chamber. The novel TAP system apparatus includes a housing and, within the housing, a catalytic reactor, a collimating slit or the like for providing a resolved pulse of product gas, an analytical device for real time analysis of the product pulse, and circuitry for coordinating the product pulse with scanning of the analytical device. The TAP apparatus may also include a cryogenic surface surrounding the product pulse path, a low residence time mixing zone ahead of the reactor, and/or a manifold of the type described above.

Abstract: Composite powders for spinels, MgO.nAl.sub.2 O.sub.3 (n=1 and 2), are synthesized hydrothermally using commercially available hydroxide reactants. The synthesis is carried out in an aqueous suspension within an autoclave under a pressure of 4 Mega-Pascals (MPa) and at a corresponding saturated steam temperature of 523.degree. K. Powder characterization has shown that the particle size ranges from 2 to 10 .mu.m. Sintering of preformed green bodies comprising compressed powder, without the use of additives, is then carried out at 1873.degree. K. in one atmosphere, resulting in a spinel having a density 94% of theorietical. Structure and microstructure have been studied by X-ray diffraction and scanning electron microscopy, and compressive strength of the resulting spinels has been determined.

Abstract: A sluice type apparatus for discharging batches of material from a pressurized enclosure has a container with an upper inlet and a lower outlet each closable by a slide gate. Preferably, each slide gate has two slide gate members driven by respective piston cylinder devices so that one gate is closed while the other gate is open and vice versa. At least the slide gate members for opening and closing the inlet are withdrawn from their inlet closing position into a respective outwardly closed or sealed chamber for making it easier to keep the container pressurized. The seals between the chamber entrance slots and the respective slide gate member are not required to be precision seals because any material that may pass into these outwardly closed or sealed chambers is easily removed again.
