Abstract: An elongate gas distributing tube, which extends in a longitudinal direction of a container, is accommodated within the container that constitutes a gas storage container. Discharge ports, through which the gas is discharged, are provided only on a side circumferential wall of the gas distributing tube. Therefore, the discharged gas advances while being directed toward the inner side wall of the container. The gas distributing tube is surrounded by a gas absorbing/adsorbing material. On the other hand, the gas absorbing/adsorbing material is surrounded by a mixture, which is prepared by mixing the gas absorbing/adsorbing material with a heat storage material, such that heat is absorbed by the heat storage material contained therein.

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.

Abstract: A dehumidification plant for granular material provided with a compressed air source, control means for controlling the flow rate of the compressed air fed by the source, a heating chamber of compressed air which is in communication with the flow rate control means, a container of granular material to be dehumidified, diffuser means disposed inside the container, temperature sensor means arranged to detect the temperature of air leaving the container, and a programmable control unit. The dehumidification plant utilizes a compressed-air dehumidifying group located downstream of flow rate control means, and a flow rate adjusting group for controlling the dehumidified air coming from the dehumidifying group located upstream of the heating chamber.

Abstract: A container for use in hydrogen transfer includes structural tubular members and perforations for fluid communication with a central passage covered with a film that is selectively permeable to hydrogen, but not to other gases. The tubular member walls comprise a sturdy material to fix the hydride powder, preventing it from shifting within the container. The hydrogen flow, when being absorbed or desorbed by the metal hydride, will pass through the film both as it is absorbed in the hydride material and also after it is desorbed to pass into the central passage. Simultaneously, the tubular member material, acting as a flexible cover or support for the film, retains contaminant gases within the conduit passage, but permits hydrogen to flow therethrough. Alternatively, a flexible conduit may be interspersed within selected ones of the longitudinal structural members, and hydride material may be packed within the springs, which provide for expansion protection.

Abstract: A catalytic electrode, cell, system and process for absorbing and storing hydrogen (H2) and deuterium (D2) from the gaseous to the solid ionic form. The cell includes a non-conductive sealed housing and a conductive catalytic electrode positioned within the housing which absorbs H2 and/or D2 gas and stores it in a solid ionic form. These electrodes are formed of palladium (Pd), titanium (Ti), or zirconium (Zr). Each end of the electrode is plated with a layer of gold and encapsulated with a curable resin to form a confinement zone for H± and/or D± storage. The process includes connecting an external d.c. electric power source to each confinement zone during H2 and/or D2 gas loading of the electrode to cause a plasma-like reaction to occur which drives the H2 and/or D2 in the electrode to each encapsulated confinement to effect long-term storage of the ion form H± and D± in a solid form for later use.

Abstract: A vapor collection method and apparatus capable of capturing vapor compositions without substantial dilution. The method and apparatus utilize a material that has a surface with an adjacent gas phase. A chamber is positioned in close proximity to a surface of the material. The position of the chamber creates a relatively small gap between the surface of the material and the chamber. The adjacent gas phase between the chamber and the surface define a region possessing an amount of mass. At least a portion of the mass is drawn through the region by induced flow. The utilization of a small gap limits the flow of mass that is external to the chamber from being swept through the chamber by induced flow.

The desiccant part and activation piece are attached together and then covered, except for the portions where the two pieces are attached, with a polymer that has a low moisture vapor transmission rate, such as parylene. The apparatus may be added into an electronic device during assembly. The desiccant, or drying agent, is not activated, by removal of the activation piece, until prior to closure of the hermetically sealed electronic device.

Abstract: A highly moisture-sensitive element and method of making such element includes an encapsulation enclosure encapsulating all of the highly moisture-sensitive electronic devices on a substrate and a sealing material positioned between the substrate and the encapsulation enclosure to form a complete seal between the substrate and the encapsulation enclosure around each highly moisture-sensitive electronic device or around groups of highly moisture-sensitive electronic devices, wherein the substrate or encapsulation enclosure, or both, contain vent holes and vent hole seal material or wherein the seal material contains gaps prior to spacing the substrate and the encapsulation enclosure within a predetermined range and the gaps are filled in by spreading the sealing material.

Abstract: A capillary membrane gas dehydrator. A gaseous stream having water vapor therein flows into the tube side of the capillaries. Water vapor permeates through the fibers to the shell side. A portion of the dehydrated stream is used as a purge stream for the shell side of the dehydrator. A pressure valve meter combination is used in the bypass stream to ensure that the pressure of the purge stream is maintained at a constant level independent of any variation in the pressure of the feed stream. This ensures that if there is an increase in pressure in the feed stream there is no increase in the purge rate and no corresponding increase in purge losses.
