The organic material is inserted between two sheets of thin cloth which are, in turn, sandwiched between two thick felt pads. These pads are then sandwiched between platens made from inorganic material. The assembly is placed in a microwave oven and heated, resulting in a pressed and dried organic material.

Abstract: A vacuum dryer panel for a leather drying machine wherein a dryer panel comprising a porous screen is mounted over a perforated plate on the underside of a vacuum chamber positioned above a heated drying table on which leather skins are dried. The dryer panel comprises a layer of fine mesh screen preferably formed of a synthetic resin material mounted on a porous backing preferably formed of a synthetic resin material. The backing material is adapted to be mounted adjacent an outer side of the perforated plate and provides porosity between the screen and adjacent openings of the perforated plate. The backing material is sufficiently rigid to prevent the screen material from being pulled into openings in the perforated plate by a negative pressure on the upper side of the plate, so as to prevent marks in the dried leather. The edges of the dryer panel are folded over and incorporate reinforcing strips. Threaded fasteners fit through spaced openings in the edges for mounting the dryer panel to a vacuum chamber.

Abstract: Apparatus for reducing the water content of water-containing, granular brown coal under the action of thermal energy and pressure on the material (14) distributed flat in bed form using a press (9, 10) in which the brown coal is subjected to a mechanically applied initial surface pressure and which is furnished with orifices (21) for feeding steam (HD) which, supplying thermal energy to the brown coal, heats this, with condensation, and the hot water (HW) contained in the heated brown coal is expressed for use as a waste-heat source, a vessel (30) being provided for collecting the hot water (HW), from which vessel the hot water (HW) is passed to the orifices (21) in the press (9, 10), and which vessel is furnished with an inlet for the steam (HD) for expelling the hot water (HW).

Abstract: A method and apparatus for drying a fiber web is provided by pressing the web, preferably by impulse drying and then introducing the web into a gas pressurized zone followed by reducing the pressure in the zone, the reduction preferably being effected with cooling of the fiber web.

Abstract: An air press for use in drying web material, such as corrugated board, characterized by a plurality of individual plenums pressing a double-backer belt against the web material as it is being transported over a plurality of steam chests for drying. Each of the plenums is provided with brushes for sealing the periphery of the plenum relative to the belt and has an individual blower and an individual venting door so that both the humidity of the air in the plenum, as well as the pressure, can be individually controlled.

Abstract: A hot chuck assembly characterized by a platen suspended over a base assembly by four, equally spaced mounting assemblies. The suspension points on the platen are provided as close as possible to its upper, wafer support surface so that thermal expansion of the platen has a minimal effect on the position of a supported wafer. Each of the mounting post assemblies includes a pair of resilient leg portions which can flex in a radial direction to absorb radial expansion or contraction of the platen. In consequence, the hot chuck assembly of the present invention minimizes both lateral and axial displacement of a supported integrated circuit wafer as the platen heats and cools.

Abstract: In a preferred embodiment, a commercial dry-cleaning or pressing apparatus has a perforated horizontal substrate with a heated pressing iron pivotably mounted thereon for lowering onto and pressing a garment positioned on the upper face of the perforated substrate, the perforated horizontal substrate having perforations therein through which water vapor is passed from a mixing chamber in which pressurized outside air is admixed with pressurized water vapor after pressurized water vapor is passed through a vapor-pump-outlet inclusive of a restricted vent of a water-vapor collecting chamber from enclosed water-vapor space thereof, above heated water having a water-vapor producing transducer therein within an enclosed water-containing vessel also enclosing the water-vapor collecting chamber thereabove, with a water-vapor pressurizing pump with an outside-air intake and feeding air into the water-vapor collecting chamber and concurrently pressurizing an outgoing mixture of air and water vapor from the water-vapor

Abstract: Method and apparatus for use in drying biomass particles provide a dryer having a chamber for a predetermined volume of biomass particles with apertures distributed throughout one boundary of the chamber enabling hot gas to be introduced and forced through the particles to exit from the opposite boundary. The gas stream to the chamber is so regulated that a layer of particles adjacent the opposite boundary functions as a relatively cool filter bed operable to prevent, to a desired extent, noxious liquids, gaseous, or particulate emissions from exiting from the dryer.

Abstract: Wet laundry 10 in a vessel (12) supported on a drainage plate 14 is dewatered by a combination of mechanical pressure applied by a platen 33 and air flow through the platen and laundry. The platen is initially brought down upon the laundry by a cylinder 42 to compress it and squeeze out about half of the water, and drying air is simultaneously forced through the vessel from top to bottom via the platen and plate to remove additional moisture. The platen pressure may be reduced to enhance the air flow.

Abstract: An apparatus for the molding of seals, packings and the like comprising a curing chamber, the curing chamber being heated by a gaseous medium circulated within, and being selectively, substantially closed to ambient temperatures during the curing process. Provision is made to dispose at least one mold in the curing chamber through a lateral opening and to place the mold under compression during the curing process.

Abstract: A process and apparatus for drying textile stock and the like which assures even, thorough and quick drying of a batch of stock. The process embodies the steps of passing heated air under pressure through the stock along a multiplicity of paths so that the air will not channel itself, but passes through the stock substantially completely in contact with all of the wet fibers. A second feature of the process is the concept of pressing the stock while passing heated air through the same along a multiplicity of paths. The process is further characterized by engaging a column of the stock between two platens, both of which are perforated and one of which is movable and applying a head of heated air under pressure above the movable platen so that the pressure of the air causes the platen to act somewhat as a piston, the air also being forced through the holes in the movable platen to pass through the stock along a multiplicity of substantially discrete paths.

Abstract: A method of reducing the liquid content of a mixture of a liquid and a particulate solid by subjecting said mixture to pressure filtration in a tube pressure filter in which, after the formation of the filter cake on the filter element of the tube pressure filter, a gas is forced through the filter cake at a pressure which is at least one third of the maximum pressure employed to form the filter cake on the filter element.

Abstract: An apparatus for drying ceramic bodies in which a framework of horizontal pipes and spacer bars define vertical columns beneath which a platform is disposed. The drying medium is circulated through the chamber containing the rack and through the pipes of the rack which have outlets for the cooling medium therealong. The ceramic bodies are stacked on the platform and the stacks are held pneumatically when the platform is lowered to remove the bottom article from each stack, additional articles being fed to the stack from the top. Plates on opposite sides of the stack are shifted back and forth by a crank arrangement to impart a quasi-sinusoidal movement to the gases around the bodies in the stacks.
