Abstract: A process for producing a polyvinyl alcohol film or fabric having a modified non-porous surface which can be used to form disposable protective clothing, wraps, and articles similar to TYVEK® by impinging steam on at least one surface.

Abstract: The invention relates to fire and impact resistant windows and building structures which contain a window composed of a specific order of layers containing a novel fire resistant layer. The invention further pertains to coating compositions for use with structures containing the windows.

Abstract: The invention relates to security glass laminates having high strength and impact resistance. The laminates consist of a pane of glass sheets with an ionomer interlayer. The ionomer consists of at least 17% by weight of acrylic acid groups which have been neutralized with a lithium salt.

Abstract: The present invention relates to optically clear fire resistant and impact resistant windows having at least one air gap and at least one fire resistant layer. Optionally there is also an anti-spall layer.

Abstract: The invention relates to the purification of recovered AB5 alloy which is obtained from spent nickel/metal hydride storage batteries by the selective removal of any Ni(OH)2 and the recovery of lanthanum without dissolving any AB5 alloy.

Abstract: The present invention provides a process of recovering AB5 and/or AB2 as well as other metals from spent nickel metal hydride batteries from a slury by a series of separation steps utilizing the screening off of larger metal particles, removal of magnetizable small metal particles from a filter and then separating AB5 and/or AB2 by passing the filtrate through a froth flotation step to separate AB5 and/or AB2 from lighter small particles.

Abstract: A method for rejuvenating a reverse osmosis (RO) membrane which is subject to biofilm and other contaminants in an aqueous system through the use of a free molecular iodine solution at a pH of about 2.2 to 4.0.

Abstract: There is provided a composition and a method for forming fire resistant panes containing borate-phosphate anions and the window pane and window assemblies prepared therefrom.

Abstract: A centrifugal pump mounted in an external housing. The pump has a split housing containing an impeller with outwardly extending vanes that is mounted on a drive shaft. The drive shaft at one end is mounted to a sealed bearing within the external housing and at the other end to a drive.

Abstract: The present invention provides electrolytes for use in electronic devices which contain imidazolium salts in combination with high boiling aprotic solvents having lower flammability and lower toxicity than acetonitrile electrolytes.

Abstract: The disclosure defined by this invention provides a method for extruding thermoplastic polymers which includes the step of creating high pressure steam in the extruding apparatus so as to prevent scorching and to solubilize contaminants. The method can be used in a neutralization step of ionomers in an extrusion process to obtain an extrudate having good light transmission and improved impact resistance.

Abstract: The present invention relates to a method for the volumetric decontamination of radioactive metals. The method includes the step of precipitating out radioactive gamma and beta emitting nucleotides and then recovering non-radioactive metal compounds.

Abstract: An electrochemical device having an operational voltage up to 4.5 V in combination with a high concentration of an electrolyte salt consisting of a tetrafluoroborate salt and a eutectic of two solvents in which ethylene carbonate is one and an improved carbon electrode a preferred electrochemical device is a capacitor.

Abstract: The invention relates to a cutting and lubricating suspension composition containing gelatinous particles for cutting hard and brittle material with a wire saw. The composition contains an in situ partially neutralized polyelectrolyte and a glycol which suspends abrasive particles used in the cutting operation.

Abstract: A method is provided to treat skin to restore barrier homeostasis and to promote normal stratum corneum function by applying to the skin a liquid composition which forms a phase inversion membrane. The amount of solids in the liquid composition is varied so as to provide a desired degree of porosity to the resulting membrane.

Abstract: A breathable protective garment or laminate for protection against chemical and/or biologic agents which contains one or more scrim layers which contain anti-microbial and/or anti toxic chemical agents. The garment or laminate is also self-decontaminating.

Abstract: Carbon electrodes for a capacitor having conditioned carbon elements in combination with a high concentration of an electrolyte tetrafluoroborate salt and a non-aqueous aprotic solvent to provide an operational voltage up to 4.5V and capacitors used with the carbon electrodes.

Abstract: A filtration apparatus for use in a system containing a gas or liquid to be decontaminated. The apparatus has at least one housing for a filter that removes contaminants from a gas or liquid which include biologics and chemicals. The housing contains an inlet portion and an outlet portion in association with valves for closing or regulating the flow of gas or liquid to be decontaminated by the filter. A differential pressure gauge is optionally provided to monitor the pressure in the housing and to indicate when the filter should be replaced. One or more housings can be used for the apparatus. The apparatus is useful for securing water systems, gas delivery systems, and vacuum systems.
