Abstract: A drying device for drying a gas comprises parallel cooling branches, at least one of which is in its active state at any given time. A gas-coolant heat exchanger arranged in each of the cooling branches has a first channel through which the gas to be dried flows in the active state of this cooling branch and a second channel which, in the active state of this cooling branch, forms an evaporator for a coolant circulating in at least one coolant circuit. The drying device further comprises an ambient-air input line, an ambient-air output line and an ambient-air conveyor. In the passive state of a respective cooling branch, the ambient-air input line and the ambient-air output line are connected, at least for a time, with this cooling branch by the switching device and the ambient-air conveyor conveys ambient air through the first channel of the gas-coolant heat exchanger arranged in this cooling branch.

Abstract: Glassy articles are prepared by subjecting to hydrolysis and policondensation a solution or suspension of a suitable precursor, mainly comprising a silicon alkoxide, and by drying the obtained gel in a pressure chamber, the gel solvent having been substituted by a non-protic solvent, mainly acetone, under nitrogen flowing, at temperature and pressure conditions lower than the gel solvent critical values. The dried gel is then densified by a thermal treatment.

Abstract: As a metal assembly, which defines partially open voids in which liquid accumulates is conveyed through a heat-treating station, the hot air is blown across the open end of the void to produce a zone of low pressure at the surface of the liquid. The reduction in pressure and relatively high temperature promote rapid vaporization of the liquid while discouraging boiling of the liquid.

Abstract: A wafer dryer and method featuring a nebulizer which emits a pressurized drying liquid stream that converges with an opposed pressurized non-reactive carrier gas stream to produce a drying liquid fog. The pressurized non-reactive gas spray device is disposed partially within a tub and partially within a wafer bath vessel housing a wafer to be dried. The tub has a vent port for allowing the drying liquid fog to pass into the wafer bath vessel to adhere to exposed wafer surfaces and displace remaining liquid on wafer surfaces, thus drying the wafer. The tub may further include a drain for draining drying liquid not converted into the fog or which has condensed. The vent also may include means for retaining larger drying liquid fog particles which allows smaller drying liquid fog particles to pass into the wafer bath vessel.

Abstract: An air dryer and process employs a jet engine for producing high quality dried products. A turbofan jet engine in an air-drying system uses both thermal and non-thermal air-drying. The turbofan jet engine is housed within an air distribution chamber for directing exhaust air and bypass air from the jet engine into a product drying tube, where it is dried through a combination of thermal drying from heat content in an engine exhaust, and by the kinetic energy of air flowing past the product traveling through the drying tube, that may include a physical impediment for retarding retard the speed of the product solids flowing in the air stream through the tube.

Abstract: An increased air pressure forced hot air towel warmer comprising a substantially airtight enclosure configured to be more desirable and user friendly when placed in close proximity to a tub or shower whether mounted within cabinetry, on the wall or when permanently installed between existing standard 16 inch on center wall support studs while protruding as little as possible into the room. Intended for use with large area plush towels and bath sheets for which insertion in a limited width wall enclosure or shallow depth cabinetry leads to greater vertical depth of towel material to be penetrated and substantially increases the resistance to air flow, therefore back pressure, thereby necessitating increased supply pressure to maintain adequate hot air flow through the towel. Increased supply pressure is created without objectionable noise by use of low noise rotary blowers and associated pressure accumulator cavities arranged in tandem such that their respective pressure gradients are additive.

Abstract: A self-cleaning centrifugal pellet dryer and method for removing surface moisture from pellets and enabling complete removal of all pellets from the dryer after each drying cycle.

Abstract: A method of decontamination includes generating a decontamination gas by evaporating an aqueous solution in which the decontamination gas with a higher boiling point than water is dissolved. The decontamination gas is charged into a hermetically sealed decontamination chamber, and then condensed therein. A condensed liquid layer is formed in a form of a thin film on an outer surface of a decontamination subject in the hermetically sealed decontamination chamber. The condensed liquid layer is evaporated at least partially by supplying unsaturated gas into the hermetically sealed decontamination chamber. The unsaturated gas does not saturate in the hermetically sealed decontamination chamber. The decontamination gas is re-condensed after the evaporating step to re-form the condensed liquid layer, by closing supply of the unsaturated gas and re-charging the decontamination gas into the hermetically sealed decontamination chamber.

Abstract: A method of treating a waste stream comprises a vacuum treatment to promote disintegration of the waste material by “flash vapor” production, causing a swiftly vaporizing fraction inside the material to literally explode or shred apart the matrix of the material as a whole. A main processor operates at a level of vacuum that determines a given boiling temperature for a vaporizing fraction, and one which lower than the fraction's boiling temperature for the local vicinity's barometric pressure (eg., atmospheric pressure). The input stream is pre-heated to above the given boiling temperature for that fraction as determined by the main processor's vacuum level without, however, going over the boiling temperature for the local barometric pressure. It is then introduced into the vacuum of the main processor whereby a minor percentage of the vaporizing fraction flashes into vapor, and this presumptively promotes destruction and/or disintegration of the material.
