  • Publication number: 20120260515
    Abstract: A hydraulic exsiccate device lessens the presence of or prevents water vapor from entering the fluid reservoir of hydraulic machines which helps to reduce or eliminate damage to hydraulic systems used in environments such as boating, utilities, construction, manufacturing, fishing, industrial, marine, agriculture, military, mining, and so on. The hydraulic exsiccate device eliminates hydraulic reservoir fill caps, and in their place, the hydraulic exsiccate device is used as a cover fitting for closing the fluid reservoir (configured to conduct hydraulic fluid in the hydraulic systems) which operates to lessen the presence of or prevent water vapor from entering the fluid reservoir.

  • Publication number: 20090114553
    Abstract: The present invention provides devices and methods in which humidity is regulated within a housing to reduce over-drying of moisture, sweat, and any other deteriorating liquids introduced into a leather-based product by its use. This over-drying of the leather-based product results in an undesired reduction in the amount of moisture content remaining in the leather which decreases the life span and tactile sensitivity of the leather-based product. A moisture-absorbing chemical, enclosed within a container, is positioned within the housing to stabilize a humidity level within a desired range. This humidity level reduces over-drying of the leather-based product by regulating the amount of moisture that escapes the leather-based product while in the housing. As a result, the life of a leather-based product, such as a sporting glove, is extended by reducing the deleterious effects caused by over-drying of the leather within the product.

  • Patent number: 6785980
    Abstract: A compressed air supply system includes a compressor and an air dryer connected to receive compressed air from the compressor. The dryer includes a desiccant bed through which the compressed air flows to provide dry compressed air, and a blow-through valve operable to connect the desiccant bed to atmosphere. Secondary and primary reservoirs located remotely from the dryer are connected to receive dry compressed air from the dryer. Control components integral with the dryer are provided for controlling a charging operation by controlling air flow from the compressor through the dryer for charging the primary and secondary reservoirs with dry compressed air. The control components also control a purging operation by controlling air flow from the secondary reservoir through the dryer desiccant bed and through the blow-through valve to atmosphere in order to purge the dryer, while maintaining an initial air pressure within the primary reservoir.

  • Patent number: 6634119
    Abstract: Disclosed is an adsorptive ethanol drying apparatus in which microwaves are applied during the regeneration of an absorbent conducted in a continuous adsorption process for drying ethanol, so that the absorbent regeneration can be rapidly achieved at a temperature lower than that used in a conventional heating type regeneration method and within a reduced processing time, thereby being capable of allowing an efficient use of energy while improving the productivity per adsorbent mass. A method for operating the adsorptive ethanol drying apparatus is also disclosed. At an adsorption step, a vaporized ethanol azeotropic mixture is forced to pass through adsorption towers to adsorb water contained in the vaporized ethanol azeotropic mixture to an adsorbent charged in each of the adsorption towers while condensing ethanol in a storage tank.

  • Patent number: 6568100
    Abstract: A gas dryer includes a housing, and a drying drum in the housing which is permeable to allow a flow of gas through the drum between its opposite first and second ends. A first flow guide is located at the first end of the drum and a second flow guide is located at the second end of the drum. The first and second flow guides define between them a primary region of the drum for a primary gas flow to flow through the drum, and a secondary region of the drum for a secondary gas flow to flow through the drum, and are mounted for rotation about the drum axis so that boundaries between the primary and secondary regions rotate around the drum. The permeable structure of the drying drum and the flow guides allow the primary and secondary gas flows to flow through their respective regions of the drum without significant mixing.

  • Patent number: 6502328
    Abstract: A seal for an opening defined by a sidewall portion of the pressurizable tank. The tank contains desiccant for drying gases which pass through the desiccant. An elongate antenna extends from an interior portion to an exterior portion of the tank and is used for carrying microwave energy to the desiccant for regeneration of the desiccant. The seal has an insulator with an interior surface for receiving engagement with the antenna at the opening of the tank. In one embodiment, the interior surface of the insulator is tapered such that a distance between opposing portions of the insulator reduces as the insulator extends in a direction through the opening toward the exterior of the tank. The antenna has a cross sectional dimension which reduces in size as the antenna extends in the direction through the opening toward the exterior of the tank.

  • Patent number: 6408535
    Abstract: A machine for processing semiconductor wafers and similar articles has an ozone remover connected to a processing chamber. The ozone remover has a light chamber surrounded by reflectors. Ozone and other processing gases and vapors flow out of the processing chamber and into the light chamber. Ultraviolet lights in the ozone remover flood the light chamber with ultraviolet light, converting ozone into oxygen. The amount of ozone released into the environment is reduced. A recirculation line receives the gases and vapors flowing out of the ozone remover. Oxygen and any remaining ozone are separated from other gas and vapor components and are recycled back to an ozone generator, to increase the ozone generator efficiency in supplying the machine with ozone.

  • Patent number: 6112428
    Abstract: A solar powered air drying system which maintains a dry atmosphere inside a sealed volume. The system uses electricity produced by a solar panel to regenerate daily a desiccant. The desiccant drys the air in a sealed volume which includes the waveguide run and antenna for a Radio Frequency target. The system comprises a solar powered air dryer which operates in conjunction with the natural diurnal temperature cycle. During morning hours, the air volume in the sealed volume is heated by naturally increasing daytime temperatures and the sun and expands, forcing air out of the sealed volume into the solar powered air dryer. The forced air then travels through a desiccant column which includes the desiccant prior to being vented into the environment. Simultaneously, the solar panel provides electrical current to an electric heater which heats the desiccant driving off its stored water. The forced air from the sealed volume then carries the desiccant's moisture with it into the environment.

  • Patent number: 4444595
    Abstract: Possible emission of hydrogen sulphide from building materials incorporating a sulphide-containing constituent, for example ground blast furnace slag, can be suppressed or prevented by the application of a surface covering composition containing gypsum plaster and a metal compound capable of reacting with hydrogen sulphide to form a stable sulphide. It is preferred that the metal compound should have no substantial effect on the setting rate of the gypsum plaster, and may for example be an insoluble compound, while it is also preferred that the sulphide should be colorless and insoluble. Preferred metal compounds are zinc compounds and especially zinc oxide. Surface covering compositions for the purposes of the invention may contain from 0.01 to 1% by weight of the metal compound. The sulphide-containing constituent may be in a building structure or may itself be contained in a surface covering composition of rendering.
