Abstract:
A mobile fabrication solution for onsite assemblage of earth drains for ground stabilization that includes a despooling carousel for uncoiling corrugated tubing from a stock supply, and for feeding the stock tubing into an extrusion head unit. The head unit contains counter-rotating wheels that grip and drive the tubing out through a collet into a filter sock and into a collection trough. One end of a stock supply of fabric filter sock is attached to the collet exteriorly of the head unit to the collet and is unrolled along the trough. When the corrugated tubing is ejected it fills the sock within the trough and may be cut to the desired length onsite, eliminating waste.
Abstract:
A railway vehicle component, wherein the component is a partition or a light cover, and wherein the component is molded or formed from a thermoplastic polymer composition comprising: a siloxane-containing copolymer in an amount effective to provide a total of 0.2 to 6.5 wt % of siloxane units based on the total weight of the polymers in the thermoplastic polymer composition, a bromine-containing polymer in an amount effective to provide 9 to 13 wt % of bromine, based on the total weight of the polymers in the thermoplastic polymer composition, and optionally a third polymer, wherein the wt % of the siloxane-containing copolymer, the bromine-containing polymer, and the optional third polymer, sum to 100 wt %, and 0.05 to 10 wt % of a light diffuser additive, based on the total weight of polymers in the thermoplastic polymer composition.
Abstract:
A membrane cartridge is manufactured by repeatedly folding and joining two strips of membrane to form a cross-pleated cartridge with a stack of openings or fluid passageways configured in an alternating cross-flow arrangement. The cartridge can be modified for other flow configurations including co-flow and counter-flow arrangements. Methods for manufacturing such cross-pleated membrane cartridges, as well as apparatus used in the manufacturing process are described. Cross-pleated membrane cartridges comprising water-permeable membranes can be used in a variety of applications, including in heat and water vapor exchangers. In particular they can be incorporated into energy recovery ventilators (ERVs) for exchanging heat and water vapor between air streams being directed into and out of buildings.
Abstract:
A grip teaching device for encouraging an individual to maintain a proper grip of sporting equipment. The grip teaching device has a body member for placement onto the sporting equipment and can be secured by a securing device, such as a strap. The grip teaching device also includes an index finger receiving area which receives the individual's index finger to promote an appropriate placement of the index finger, and in turn forces the remaining fingers into proper alignment.
Abstract:
Silicone polycarbonate block copolymers are disclosed that have a high elongation before yield, are clear, and have elastomeric properties. Generally, the silicone blocks are very short (less than about 50 organosiloxane repeat units) and the silicone blocks are substantially isolated from each other by bisphenol carbonate spacers.
