Abstract: Cast semi-permeable membranes made from synthetic polymer used in reverse osmosis, ultrafiltration and microfiltration are treated with a non-leaching antimicrobial agent to prevent its bio-fouling and bacterial breakthrough. The semi-permeable membranes include a polymeric material and a non-leaching antimicrobial agent that is incorporated into and homogeneously distributed throughout the polymeric material. The polymeric material, in the case of one membrane, may be cellulose acetate. In the case of thin film composite polyamide membranes, the antimicrobial agent is incorporated in a microporous polysulfone layer that is sandwiched between a reinforcing fabric and an ultrathin polyamide material. The invention also includes a treatment of flat and hollow fiber semipermeable membranes made with polysulfones and polyvinylidene fluoride.

The base structure includes a moveable chassis having opposing front and rear ends, a pair of vertical support posts extending upwardly from each of said the front and rear ends, a generally U-shaped center support member horizontally and rotatably displaced between said the upwardly extending free ends of the pair of vertical support posts. The retaining frame is attached to the center cross member, has a generally rectangular construction and includes a pair of retaining members, a pair of support members joined at the underside of said the retaining members, and securing flanges fixed to the retaining members. In an alternative embodiment of the truck bed assembly holder, the retaining frame includes retaining members which are expandable in the traverse direction of the center support member.

Abstract: A method of preventing the growth of heterotrophic bacteria and the subsequent establishment of a biofilm on the surface and in the micropores of an antimicrobial synthetic ion exchange resin. An antimicrobial synthetic ion exchange resin that prevents the growth of heterotrophic bacteria and the subsequent establishment of biofilm on the surface and in the micropores of the resin. A broad spectrum organic antimicrobial agent that is water insoluble and thus precipitates out and becomes encapsulated within micropores of the resin during suspension polymerization. The antimicrobial agent is submicron sized and has a high surface area. The antimicrobial agent protects the antimicrobial synthetic ion exchange bead from the growth of heterotrophic bacteria and the subsequent establishment of biofilm on the surface and in the micropores of the resin. The antimicrobial agent is nontoxic, noncarcinogenic, substantially nonleaching and durable over the lifespan of the bead.

Abstract: A process and apparatus for the production of reformed gases. Natural gas and/or liquid hydrocarbons and oxygen are combusted in a first stage to produce carbon dioxide and water. The products of combustion are conveyed to a second stage. Reforming gas or atomized liquid hydrocarbons and oxygen are injected into the second stage and mixed with the products of combustion to react with the carbon dioxide and water to produce carbon monoxide and hydrogen. The process and apparatus are particularly adapted for use in supplementing the reform gases produced in a Direct Reduced Iron plant wherein iron ore is reduced to iron inside a shaft furnace. The process and apparatus may also be used to provide heated enrichment natural gas or liquid hydrocarbons for use as a source of carbon in the shaft furnace to provide for carburization of the iron. Additionally, the process and apparatus may be used as a process control device for controlling the temperature of the reformed gases flowing to the shaft furnace.

Abstract: A user wearable wrist support formed of low temperature moldable, formable plastic, normally closed-cell foam laminated between surface sheets of fabric. The wrist support comprises a curvate clasp having a generally self-supporting C shaped cross section, with the clasp encircling the wrist of the wearer. The clasp is secured in position by a strap. A palmar stay extends transverse of the clasp onto a palmar pad integrally extending from a side of the clasp. In one embodiment the clasp is provided with outwardly extending wrist support rests alongside the stay for supporting the clasp on a planar surface. In another embodiment the support comprises two sheets of plastic material of different densities and hardness sandwiching and embedding a stay therebetween. The device is fabricated by first creating a sheet of foam laminated with at least one surface fabric sheet. Blanks for forming the clasp are cut from the foam sheet and subjected to selective compression, heat, and molding to form the support.

Abstract: An electro-mechanical liquid level float switch that continuously actuates a switch on sensing a change in the liquid upon reaching a threshold level, where the float-switch requires manual reset once the switch has been actuated. The float switch has an elongated stem with a reed switch embedded in one end of the stem, and a float with a magnetic portion. The float is constrained to move between a stop below the switch and an upper stop above the switch. When the float is abutted against the upper stop, it is aligned with the switch. Once aligned with the switch, the switch is actuated. The float is held is alignment with the switch by a magnet located in the upper stop, where the magnet can support the weight of the float. Once the switch is actuated it remains actuated, unless the float is physically separated from the magnet.

Abstract: An emission control device and method are provided for treating exhaust to reduce pollutants contained therein. The device includes a first chamber through which the exhaust passes. First and second metal grids are disposed within the first chamber at a predetermined distance from each other. Voltage is supplied to the insulated first grid by an electrical induction coil at a predetermined frequency depending upon the application. Electrical charges are generated between the first and second grids which electrically ionizes the exhaust stream. The exhaust stream is then further treated at a second chamber having strata. The strata can further include or exclude noble metals for treatment of the exhaust.

Abstract: The invention relates to a swivel adapter-coupler that is to be positioned between a conventional fixed drop elbow on the end of a hose of a tanker truck for an underground storage tank. The other end of the swivel adapter-coupler attaches to the pipe adapter (either the fill pipe or the vapor pipe) of the underground storage tank, in the conventional quick-connect type connection. The swivel adapter-coupler permits loops and kinks in the hose to be removed by rotating the swivel adapter-coupler in the proper direction. Likewise, the invention relates to a rotatable drop elbow to replace the conventional fixed drop elbow at the end of a hose on a tanker truck. The rotatable drop elbow eliminates loops and kinks in the hose by merely rotating the drop elbow in the proper direction.
