Abstract: An improved vane type pump capable of operating either as a high rate of flow or high pressure pump change of rotation only is disclosed. The construction, arrangement and dimensioning of the operative elements of the improved vane type pump provides an angle of intercommunication between inlet and outlet means during rotation and an automatic liquid seal to assure an uninterrupted flow of liquid being pumped through inlet means for discharge through outlet means.

Abstract: A plastic sheet band multi-packaging device is disclosed as having means to facilitate carrying thereof in an economical and efficient multi-packaging design. The assembly of plastic sheet band multi-packaging devices to containers can also be greatly enhanced by folding techniques prior to and/or during assembly.

Abstract: A pull type asphalt paver for spreading asphalt onto a road surface is disclosed as having means to avoid dump truck damage to the paver during operation and transporting thereof, means to readily enlarge the width of an asphalt layer on a road surface, and means to facilitate the metering and control of asphalt discharged by the paver on a road surface.

Abstract: An assembly machine for interconnected carrier devices is disclosed as including carrier assembly means that move in a closed triangular path and are arranged to assemble the interconnected carrier devices to containers moving in a linear path, beginning on one or another side or margin of said containers that is generally transverse to the movement thereof, depending on the direction of movement of said carrier assembly means in the closed path.

Abstract: Unfrozen cellular substances are conditioned by a reduced pressure environment for subsequent processing. Cellular liquid is vaporized from the unfrozen cellular substance by a combination of reduced pressure and temperature control at a rate which is not greater than the vapor transmission rate of the rupturable cell walls of said cellular substance in order to remove said vaporized cellular liquid while keeping the cell walls intact.

Abstract: A liquid composition for treatment of fabrics is disclosed as having a silicone glycol copolymer of nonionic series, a phosphate derivative of anionic series, and a compatible liquid base. Other beneficial ingredients may include a detergent, emollient, color, perfume, thickeners, liquid softening agents and soil retardants.

Abstract: A scrapless multi-packaging device for a plurality of containers is formed from a stretchable and elastic sheet of plastic material including laterally connected pairs of sheet material bands arranged in longitudinal rows and with longitudinal connections between adjacent sheet material bands in each row, the connections between said sheet material bands being creased to provide automatic opening of the sheet material bands in upstanding relationship for assembly to containers. The connections may also be perforated to facilitate separation into groups of bands as well as into individual bands.

Abstract: The method for manufacturing interconnected multi-packaging devices from elongated flattened plastic tubular elements is disclosed.

Abstract: An extension splint is disclosed as having an elongated frame including a pivoting foot plate and frame brace in order to be readily collapsible as well as being operable in conjunction with means for longitudinally extending the elongated frame above the foot plate in order to apply an extension force to the leg.

Abstract: Silver-heparin-allantoin complex and process for making same is disclosed. The silver-heparin-allantoin complex is prepared by a novel process in either powder or solution form. The silver-heparin-allantoin complex provides a non-thrombogenic, self-sterilizing compound for application to polymeric devices such as prosthetic values, small diameter arterial grafts and the like to avoid thrombus formation and infection of polymeric devices.
