Abstract: The present technology relates to laminates for lithium-ion batteries comprising at least one cathode layer; at least one anode layer; at least one electrolyte layer disposed between the at least one cathode layer and the at least one anode layer; and a viscosity modifier present on at least a portion of the laminate which limits the penetration of reactive fluids into the laminate and thereby controls the extent of oxidization of the anode, and prevents the formation of dendrites in said laminate. The present technology further relates to methods for preparing such laminates, and lithium-ion batteries comprising same.

Abstract: A working roller for a rolling mill for laminating a sheet of alkali metal or alloy thereof into a film is disclosed. The working roller has a cylindrical center portion defining a central axis, the center portion having an outer surface defining a lamination surface; and first and second frustoconical portions extending from first and second ends of the center portion respectively. When the central axis is straight, an angle between the outer surface of the center portion and an outer surface of each of the first and second frustoconical portions is less than 0.05 degrees. A width of the center portion is greater than a width of each of the first and second frustoconical portions. The width of the center portion is less than a sum of the widths of the first and second portions. A rolling mill having two such working rollers is also disclosed.

Abstract: A sanitizing system is provided for use in a bathing unit system including a receptacle for holding water in which a halide salt has been dissolved and a circulating system for removing and returning water from and to the receptacle. The sanitizing system includes a sanitizing device having a housing configured to be positioned in fluid communication with the circulation system and an electrolytic cell positioned within the housing so that when power is applied to the electrolytic cell, the halide salt dissolved in water flowing through the housing is converted to an amount of free halogen. A controller controls an amount of power supplied to the electrolytic cell so as to control the amount of free halogen being generated. The amount of power supplied may be adjusted, for example, based on an amount of usage of the bathing unit system, a usage of a circulation pump and/or based on a water temperature. A user control interface for the sanitizing device is also provided.

Abstract: The material of the present invention is a camouflage printed flame retardant material utilizing the F. R. Camouflage Printing, exclusive to the Canadian armed forces which printing exhibits an infra-red reflectance. The camouflage material may comprise staple-length fibers, continuous filaments or yarns, tapes, and the combinations thereof. Further, the material may comprise one or more layers of similar or dissimilar substrates, such as wovens, nonwovens, knits, twills, felts, fleece, and films.

Abstract: The present invention relates generally to a woven product exhibiting arc protection, and specifically to a woven product which exhibits an arc thermal protective value of at least 8.0 throughout the period of at least 125 cumulataive wash and wear cycles. The woven product comprises an aramid fibrous component and a flame retardant rayon or malamine fibrous component. The fibrous components are preferentially blended in the ratio of at least 50% aramid to the remainder flame retardant rayon or malamine.

Abstract: The present invention is directed to a durable and imaged flame-retardant nonwoven fabric that can be used for flame-retardant apparel and other related applications. The fabric is formed by providing a precursor web consisting of a blend of melamine fibers and aramid fibers. The precursor web is hydroentangled on a three-dimensional image transfer device for formation of the fabric. The resultant fabric provides desirable air permeability and Thermal Protective Properties.

Abstract: The instant invention is directed to dyed fabric blends of aramid fibers and flame resistant (FR) cellulosic fibers, which retains a substantial amount of its strength and durability after dyeing. The dyeing process comprises the steps of: providing a fabric comprising a blend of aramid fibers and cellulosic fibers, dyeing the cellulosic fibers of the fabric, and dyeing the aramid fibers of the fabric. Dyeing of the aramid fibers being preformed with low agitation, an aryl ester carrier, and, preferably, at a temperature between 100-110° C.
