The chamber includes a cylinder sealed with probe-puncturable membranes into a sealed compartment with a reagent composition therein for the test used. The reagent chamber is used in a test unit of the test apparatus.
Abstract: A method for the concentration and separation of a sterol-containing plant mixture employing a single, rotary, thin film horizontal evaporator for saponification of the mixture in a reaction zone, evaporation of volatile by-products, and discharge of a soap product and free sterol mixture in an evaporation zone for subsequent separation, purification, and recovery of free sterols and a soap product.
Abstract: A wakeboard having rear and front center fins and a pair of spaced-apart, generally parallel, canted rear and front asymmetric side fins to provide enhanced rider control and performance of the wakeboard during maneuvers.
Abstract: A window guard for a window opening to prevent a child or animal from passing through a window. The window guard includes side frames fastened to the sides of a window frame and a plurality of spaced-apart, transverse, tubular, width-adjustable crosspiece elements to form a grid pattern between the side supports to prevent passage of a child or animal. The crosspiece elements include user-removable, tension-biased, locking clips at each end, to lock the crosspiece elements in a locking position, but to permit easy removal, when required.
Abstract: A method and system for dispensing cryogenic fluids, such as liquified natural gas (LNG), using a swivel bayonet joint interconnecting first and second sections of cryogenic pipe. The swivel bayonet joint includes a male bayonet joint and a corresponding female bayonet joint. An insertion stem of the male bayonet joint is dimensioned to have a very high tolerance fit within the receiving sleeve of the female joint that extends a sufficient length for formation of a vapor trap by the cryogenic fluid between the insertion end of the stem and the clamp end of the receiving sleeve. The vapor trap prohibits movement beyond the vapor trap of any cryogenic fluid passing through the joint, consequently, elastomeric seals in the bayonet joint remain insulated from extremely cold temperatures of the cryogenic fluid.
Abstract: A cross-flow filtration device which receives a feed stock at a feed end face and separates the feed stock into filtrate and retentate. The device has a structure formed from a plurality of substantially parallel monolith segments of porous material, each segment having a plurality of passageways which extend longitudinally from the feed end face to a retentate end face of the structure. The structure contains a filtrate conduit network comprised of both an intersegment filtrate conduit, formed by the arrangement of the segments, and at least one intrasegment filtrate conduit formed within at least one segment. The filtrate conduit network provides low pressure drop flow paths for filtrate flow through the porous material from the passageways to nearby filtrate conduits, and at least some of the passageways are separated from filtrate conduits by intervening passageways, thereby enabling a high ratio of passageway surface area to volume of the device and a high rate of filtrate removal.
Abstract: A high tensile strength, fluorocarbon-conductive, particle binder material useful as electrodes in a flow-through capacitor. The material comprises electrodes formed from fibrillated fine fibers, conductive carbon particles and a small amount of a polymeric binder. The method includes admixing the materials, fibrillating the polymers, and extruding the material to electrode forms.
Abstract: A polyurethane composition to provide a rigid polyurethane foam suitable for use as a core material in a composite laminate and which polyurethane composition includes an additive compound or oligomer-prepolymer having hydroxy groups for reaction with the diisocyanate of the polyurethane or which has been prereacted with a diisocyanate and which contains after the polyurethane reaction ethylenically unsaturated groups, like allyl or acrylic groups, to react with an unsaturated polyester resin. The invention includes the organic additive oligomer-prepolymer and the hybrid polyester-rigid polyurethane laminates.
Abstract: A wakeboard binding and system with a baseless beam support. The binding includes a shaped metal or plastic beam, bent or formed to define a baseless U-shaped cavity between the beam sides. The baseless beam support secures, by fasteners, the sheet material to form the boot enclosure between the upper inner flange of the beam and lower separate strips.
Abstract: A fusion-bonded carpet system and method of manufacture which method includes providing as all or a portion of the wear face surface cut yarn material in rope form prepared in rope bundles and implanting one or both ends of the rope bundle in an adhesive layer on a backing sheet to provide one or two I-bond, fusion-bonded carpet material having a selected pattern on the wear face surface. The fusion-bonded carpet has a wear face surface composed of all or part of a yarn material in rope bundle form, for example, of a multicolored random or selected pattern. The carpet material may have a backing layer and form carpet tile.
Abstract: A septic system and method for the removal of nitrogen contaminants, such as nitrates and ammonia, from a wastewater effluent, which system and method includes employing one or more zeolite tanks, which contains a regenerable, granulated zeolite material to receive wastewater effluent from a septic tank, and to capture the nitrogen contaminants, such as nitrate and ammonia, and retain the nitrogen contaminants in the zeolite material allowing the treated, decontaminated effluent to flow out of the tank into a leach field. The system and method includes for periodically regenerating the zeolite material in the zeolite tank, after the zeolite material has become substantially exhausted, and restoring the zeolite material in the zeolite tank for reuse. The system provides for removal of the displaced nitrogen contaminants generated from the regeneration of the zeolite material in the zeolite tank.
Abstract: The present invention is an article packaging system which can be easily recycled. In one embodiment, the packaging of an article comprises a sheet member comprising a base portion and first and second end portions foldable with respect to the base portion, and a film member comprising a first end portion and a second end portion, the first and second end portions being removably attached to the first and second end portions of the sheet member, respectively. More particularly, the first and second end portions of the film member comprise a pocket adapted to engage with the first and second end portions of the sheet material, respectively. In operation, the film member and the sheet member may be separated from each other after use for recycling.
Abstract: A method of treating a disease in a mammal by administering a therapeutic effective amount of an amphoteric zwitterion compound as an active ingredient. A pharmaceutical composition which comprises an amphoteric zwitterionic compound as an active ingredient in combination with a carrier and other adjunctive pharmaceutical agents.

Abstract: A fish tag harpoon which contains a shock absorbing cap on the harpoon end, and contains a sonic signal-emitter secured by elastomeric bands to the harpoon, with the emitter secured by a line to a releasable retention dart at the end of the harpoon.
Abstract: A photometer and a test sample holder, with the holder having a light-blocking, black upper section and a light-transparent, lower section test sample vial, for use with the photometer. The photometer includes an O-ring seal at an input, to the light measurement sample chamber, so on insertion of the holder, with a test sample to be detected in the test vial, the upper section blocks interfering light from the chamber.
