Abstract: A method of discharging particulate material from a first container to a lower positioned storage area being under a lower pressure than the first container. Particulate material is discharged via an upper tube section of a discharge tube communicating with the first container and permanently containing a column of the particulate material. The discharged material is directed into a pressurized stabilizer. The discharged material is directed via a lower tube section to a material feeder for forming columns of the particulate material in the upper and lower tube sections thereby reducing the pressure of the material to a predetermined normal pressure level at the input of the feeder. The material is fed to the storage area. The quantity of discharged material is controlled by the feeder. Gas flowing from the first container is extracted through the particulate material column to an environment via a throttle at an upper portion of the pressure stabilizer, thus stabilizing the discharge by making it independent of pressure variations in the particulate material column upstream of the pressure stabilizer. The feeder is stopped when a pressure increases in the particle column in the upper tube section resulting in a pressure increase in the pressure stabilizer until the pressure of the pressure stabilizer has returned to the normal level due to the extraction of gas.

Abstract: Disintegrated material is supplied to a pressure chamber by a rotatable and axially translatable screw piston. The piston is rotated while in a first axial position to transport and compact the material in a receiving chamber against a closed output valve in front of the piston. The output valve is opened and the compacted material is moved into the pressure chamber by axial non-rotative motion of the piston. The output valve then is closed, and the piston is axially returned to its first axial position while rotating in the same direction as before. The operation cycle is repeated as above. An apparatus for carrying out a process comprises an axially movable guide piston rotationally carrying and guiding the screw piston for rotation and axial movement by action of a hydraulic cylinder and a mechanism for rotationally positioning the screw piston.

Abstract: The continuous removal of solid products from a high-pressure system is achieved by operating a high-pressure pump in reverse to gradually reduce pressure at the exit line to atmospheric pressure. This process allows solid products to exit the system while at the same time maintaining high pressure in the reactor.

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 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.

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.
