Abstract: A bladder-less counterpressure garment primarily used in the treatment of a victim suffering from hypovolemic shock. The garment is made of a resilient material, like elastic, with a means for stretching the material to or near its stretch limit. This stretching supplies the requisite counterpressure to increase blood circulation to the vital organs.
Abstract: A multicell storage battery may be assembled to fit various floor space and height requirements by using standardized multicell modules having keyed connector means such that the modules can be connected only in selected orientations which facilitate the electrical connection of terminals. These standardized modules eliminate the need for standard and reverse polarity modules which existed in the prior art, and simplify battery assembly on site while allowing greater flexibility to adjust to space limitations. The keyed connectors comprise mating structures on the sides of the rectangular frame of the modules, which in combination with the modules being configured to stand vertically, create cooling ducts for the cells. An easily installed safety shield encloses the terminals of the cells and provides a front cooling duct.
Abstract: A carburetion and combustion system is provided in which the carburetor discharges a combustible fuel/air mixture in a rotating swirl from a plurality of nozzles at one end of a cylindrical combustion chamber, and discharges a rotating helical swirl of high-velocity compressor air concentrically surrounding the combustion mixture from a second set of nozzles. The high-velocity air swirl confines the flame propagation away from the combustible chamber walls and provides the walls with an insulating layer against the combustion heat.
Abstract: An electrical generating system in which exhaust steam from the turbine is recycled through the turbine to reduce feedwater requirements and condenser complexity. The turbine is an axial flow dual shaft compressor/turbine unit in which a coaxial shaft couples the turbine section to the compressor section. A portion of the energy extracted from the steam is used to power the generator and the remainer is used to power the compressor. The turbine exhaust steam is directed through compressor section and the compressed steam is then mixed with turbine inlet steam by a steam jet ejector. The compressor may be powered from either one or both shafts from the turbine.

Abstract: A perforated retainer is installed just under the top surface of the gelled electrolyte in a lead-acid storage battery to prevent the gel from crumbling and separating from the element plates when the battery is mounted horizontally. The size and density of the perforations are such that the retainer does not impede the initial introduction of the electrolyte solution. An the solution "gels", it cannot penetrate back through the retainer, but normal gas migration is not impeded by the retainer.
Abstract: A submersible flame-retardant vent plug is adapted for use in storage batteries of the type containing liquid electrolyte. The plug has inlet and outlet slots and a hollow portion providing a gas communication path. A porous flame arrester is positioned in the path. A check valve is positioned in the path between the flame arrester and the outlet slots and is adapted to be opened by gas pressure from the battery's interior and to be closed by water pressure from the battery's exterior.
Abstract: The present invention is a process for treating plastic substrates to improve their surface properties. The process involves exposing the plastic substrate to UV radiation at wavelengths of 185 and 254 nm in the presence of atomic oxygen for about 5 to 60 minutes. The treated plastic substrates have improved wettability. The process is particularly well suited for the treatment of plastic intraocular lenses and plastic packaging materials such as PVC film.
Abstract: An apparatus for washing storage batteries comprises a rinse section for removing water soluble acid, followed by a wash section to remove non-soluble contaminants. The water in the rinse section is isolated from the water in the wash section. Means are provided for collecting acid solution from the rinse section, and for filtering and recycling the water in the wash section. Batteries are moved through the sections in sequence on a carrier. In a preferred embodiment, the rinse section comprises a partitioned collecting pan underlying the carrier to create sequential rinsing in progressively less acidic rinse water and to concentrate the most acidic rinse water before the first partition for extraction as an acid solution. A drying section using air blowers along the carrier may be included after the washing section.
