摘要:
This invention outlines laminates With low capacity for heat absorption with suitable optical and thermodynamic properties for thermal control, useful in the car-making industry, in furniture, and other household, as well as In articles of clothing. Materials Incorporate several technologies efficiently regulating temperature, both for reflecting infrared light and for regulating temperature, regardless of the material color, and therefore, achieving a comfort greater to that obtained with laminates from the previous art. The invention allows obtaining also materials with no deterioration due to aging chemical reactions. In addition, this invention describes a process to obtain laminates with low capacity for heat absorption.

The present invention relates to electrical separators for batteries, especially lithium batteries, having a shutdown mechanism and also a process for their production. An electrical separator is a separator which is used in batteries and other systems in which electrodes have to be separated from each other while maintaining ion conductivity for example. Safety is very important in lithium batteries, since in contrast to other types of battery (Pb, NiCd, NiMeH) the solvent for the electrolyte is not water but a combustible solvent, for example organic carbonates. This is why it is absolutely necessary for a separator for lithium cells to possess a suitable shutdown mechanism and at the same time for it not to be able to melt down. This object is achieved by an electrical separator according to the invention that comprises a shutdown layer which consists of particles which melt at a desired temperature, close the pores of the separator and so stop ion flow. Since the separator also comprises a porous inorganic (ceramic) layer on a carrier, the cells cannot melt down as a result of a completely melted separator.

Disclosed is a fabric which includes a microbial adsorbent and which is capable of providing a microbial barrier while still being able to allow passage of water vapor. The fabric is formed from a plurality of fibers which define at least one microporous passageway which allows communication, through the fabric, between its respective first and second surfaces. In particular, a portion of the microporous passageway is defined by the microbial adsorbent so that microbes attempting to pass through the fabric via such a passageway must pass in close proximity to the microbial adsorbent. This arrangement allows the microbial adsorbent to interdict the microbe by adsorbing it. Passage of the microbe through the fabric is thereby prohibited. Laminates of the fabric with other materials are also disclosed.
摘要:
An antistatic layer of a radiation-sensitive element, such as a photographic film or paper, is formed by coating and drying of an antistatic composition comprising an aqueous solution of an amorphous antistatic material, the aqueous solution having been produced by forming a melt comprised of at least 80% by weight of vanadium pentoxide and casting the melt into a solubilizing amount of water. In addition to vanadium pentoxide, the melt can contain a glass-forming compound, such as an alkaline metal phosphate or polyphosphate, as well as an oxide of an element that exists in at least two valence states, such as an oxide of molybdenum. The radiation-sensitive element preferably includes a protective overcoat layer covering the antistatic layer.
