Thermoplastic desiccant

The invention relates to thermoplastic compositions that contain reactive isocyanate groups and that are suitable for use as desiccants for packaging moisture-sensitive goods, especially for polyurethane hotmelt adhesives that are cross-linked upon exposure to moisture. The compositions are formed by the reaction of hydroxy- or amino-containing polyols, including sugars, with an excess of polyisocyanates, and admixing the resulting product with polyurethane catalysts.

Protected organic electronic device structures incorporating pressure sensitive adhesive and desiccant

Organic electronic device structures are provided, which comprise: (a) a first portion comprising a substrate and an organic electronic device region (e.g., an OLED region) disposed over the substrate; (b) a second portion comprising a cover and a getter region; and (c) a radiation-curable, pressure-sensitive adhesive layer disposed between the first and second portions and adhering the first and second portions to one another. The adhesive layer is disposed over the entire organic electronic device region and over at least a portion of the substrate. Other aspects of the present invention are directed to methods of making the above structures.

Humidity adjusting apparatus using desiccant

A humidity adjusting apparatus includes a fan for forcedly generating airflow, a heater for heating introduced air to a predetermined temperature, a driving unit for generating driving force; and a desiccant unit having a rotational shaft driven by the driving unit and a plurality of desiccant plates supported on the rotational shaft in a radial direction. An orientation of each desiccant plate and airflow direction are periodically varied.

Structure for containing desiccant

A hermetically sealed area includes a substrate having microelectronics thereon. A desiccant is operatively disposed within the hermetically sealed area. An equipotential region is substantially maintained around the desiccant.

Satellite signature suppression shield

An inflatable shield for suppressing the characteristic radiation signature of a satellite is described. The shield is conical-shaped and made from a thin synthetic polymer film material coated with a radiation reflecting material, such as gold or aluminum. At least one subliming agent is contained within the shield to inflate the shield when exposed to heat. An ultraviolet curable slurry coats the inner walls of the shield and permanently hardens the shield upon exposure to ultraviolet radiation from a self-contained source. The shield optionally may include absorbing and desiccant agents to absorb unwanted gas and water and prevent interference with the primary mission of the satellite. Additional means may be included for moving and positioning the shield with respect to the satellite.

Accumulator desiccant bag

A preformed desiccant bag for use with a retaining clip including a preformed porous casing including a first preformed bulbous end portion of a first girth, a second preformed bulbous end portion of a second girth, a central preformed waist portion of a third girth located between the first and second preformed bulbous end portions, with the third girth being smaller than either the first and second girths to thereby provide a pronounced position for reception of a retaining clip, and desiccant in the casing.

Air desiccant system and method for automotive climate control

A method and system for climate control uses a desiccant in an automobile. The desiccant removes humidity or moisture from air passing through the ventilation system. The desiccant is recharged or dried by application of a vacuum. The lower pressure generated by the vacuum reduces the temperature at which water evaporates or boils off of the desiccant material.
