Abstract: A flame retardant adhesive tissue paper for fabricating moldable structures, particularly suitable for forming laminates for the interior of automobiles is provided. The flame retardant adhesive tissue is prepared by screen printing an aqueous paste dispersion including a flame retardant and thermoplastic adhesive dispersed therein in discontinuous pattern onto one surface of the paper. After removal of water, the drying temperatures is increased to activate the thermoplastic adhesive to adhere to the surface of the tissue with the flame retardants solids dispersed within the interior of the tissue paper. The adhesive coated tissue paper has good acoustic properties and imparts flame retardancy to a laminate including it.

Abstract: The invention relates to a novel method for the in-vivo labeling of biopolymers such as proteins, nucleic acids, lipids, carbohydrates and biodegradable plastic using isotopes, especially stabile isotopes. The invention also relates to the use of chemolithotrophic bacteria for the in-vivo isotopic labeling of biopolymers. In particular, the invention relates to the use of CO2-fixing bacteria, such as Ralstonia eurtropha and related methanogenic bacteria for the in-vivo isotopic labeling, especially for labeling using the stable isotope 13C alone and in combination with other isotopes. In addition, the invention relates to the use of isotropically labeled biomolecules in therapeutic and diagnostic applications, especially in spectroscopic methods and generally as tracers.

Abstract: A high viscosity synthetic ester base stock of about ISO 68 to 400 is formed from a neopentylpolyol condensed with at least one monocarboxylic acid selected from the group consisting of linear acids having between 4 to 10 carbon atoms and branched chain acids having from 5 to 10 carbon atoms in an excess of hydroxyl to carboxylic acid groups to form a partial polyneopentylpolyol ester that is further reacted with the same or similar acid to form a high viscosity polyneopentylpolyol ester. Lubricants formed from the base stocks have satisfactory miscibility with standard highly or fully fluorinated refrigeration fluids.

The steam iron is attachable to the steam generator, includes an iron heating element for heating the iron, and includes a circuit designed to supply power to the iron heating element, but not to the second boiling element, when the steam iron is attached to the steam generator. The steam generator also includes a steam release valve that supplies the steam and which is controlled by respective switches within the steam cleaner and steam iron.

Abstract: A process for lining an existing pipeline or conduit with a flexible resin impregnated cured in place liner by pulling in the liner and inflating an eversion bladder with air and curing the liner with flow-through steam without loss of pressure is provided. The liner includes a resin absorbent material in tubular form with an impermeable membrane forming an outer layer. The absorbent material is saturated with a thermoset resin and pulled into the existing conduit. A flexible inflation bladder is passed through a gland mounted on an eversion apparatus and everted into the collapsed liner. The gland is pressurized to isolate the eversion bladder. As the bladder reaches the distal manhole, it enters a receiving canister where it is punctured while maintaining air pressure within the bladder. Steam is then introduced into the bladder to cure the resin and is exhausted through the receiving canister. The bladder is then removed and lateral service reinstated.

Abstract: A reinforced liner for cured in place pipe rehabilitation of an existing pipeline having a plurality of high-strength low-elongation fiber bundles disposed circumferentially around the tubular liner at both inner and outer surfaces of a resin absorbent layer of the liner is provided. The bundles of reinforcing fibers are continuous lengths of high modulus fibers laid circumferentially with the ability to stretch to accommodate variations in host pipe diameter. The fibers on the inner surface are secured to a porous scrim to form an inner tubular reinforcing layer. A resin absorbent layer is formed into a tube about the inner layer. An outer layer of bundles of reinforcing fiber are formed into a tube about the absorbent layer. An outer impermeable tubular layer is wrapped around the inner layers. The reinforcing layer may include longitudinal reinforcing fiber in either or both reinforcing layers to increase the longitudinal strength of the liner.

Abstract: A process for lining an existing pipeline or conduit with a flexible resin impregnated cured in place liner by pulling in the liner and inflating it with a reusable endless inflation bladder is provided. The liner includes a resin absorbent material in tubular form with an impermeable membrane forming an outer layer. The absorbent material is saturated with a thermoset resin and pulled into the existing conduit. A flexible inflation bladder maintained on a inflation bladder spool is everted into the collapse liner which is then forced against the interior surfaces of the existing conduit, allow to cure and the bladder removed and rewound on the spool. When the everting and curing fluid is hot water, the hot water is removed and stored for reuse as the inflation bladder is withdrawn.

Abstract: A method for the trenchless installation of new underground pipe accurately on line and on grade by microtunneling to install a pilot tube, installing a drill string along the pilot pipe line using a directional drilling machine, installing a back reamer to the drill string and using a directional drilling machine to pull back the reamer and install a product pipe behind the reamer. A pilot tube is installed on line and on grade by utilizing the guidance system of a microtunneling apparatus to install a pilot tubes between jacking and target shafts. A drill string is installed to displace the pilot tubes and a back reamer is attached to the drill string with a product pipe attached to the reamer. The reamer may be pulled using any suitable pulling device such as a directional drilling machine.

Abstract: A process for lining an existing pipeline or conduit with a flexible resin impregnated cured in place liner by pulling in the liner and inflating an eversion bladder with air and curing the liner with flow-through steam without loss of pressure is provided. The bladder is stored in a pressure bladder canister coupled to a pressurized downtube and eversion elbow. The bladder is everted by introducing pressurized air into the canister As the bladder reaches the distal manhole, it enters a receiving canister where it is punctured while maintaining air pressure within the bladder a pinch valve between the downtube and elbow isolates the inverted bladder so that steam can be introduced into the bladder to cure the resin and exhaust through the receiving canister. The bladder is then removed and lateral service reinstated.

Abstract: A vacuum cleaner includes a container having an inlet for dirty air, an outlet for clean air, a coarse dust chamber and a fine dust chamber. The coarse dust chamber includes a filtering tube disposed within a rotary cylinder. The fine dust chamber includes a rotary cone. Air containing dust is drawn into the coarse dust chamber and supplied into the gap between the cylinder's inner surface and the filtering tube's outer surface. The air is rotated within the coarse dust chamber to force coarse dust to travel away from the chamber's center and air containing only fine dust travels through the filtering tube. This air is supplied into the rotary cone within the fine dust chamber and is rotated to force fine dust away from the chamber's center. Dust free air, which is travelling in the center of the rotary cone, is supplied out of the filter as clean air.

Abstract: Fusion of facing portions of the turnback portion of an installed everted resin impregnated cured in place liner installed in an existing conduit is avoided by adhering a high temperature turnback release film to a portion of the trailing end of the everting liner. After cure and removal of the downstream end of the liner, the high temperature release film is peeled away from the cured liner. This avoids the need to remove the fused portion of the turnback by cutting or excavation of a section of the liner. Fusion generally occurs due to the exotherm from the crosslinking of the thermosetting resin impregnated into the flexible lining.

Abstract: A fuser member for fixing toner to a recording medium having a fluoropolymer non-stick topcoat on a compliant silicone rubber baselayer bonded to a metallic insert is provided. The fluoropolymer is adhered to the silicone rubber baselayer using a primer of a blend of silane and a polyamide resin. The primed silicone baselayer is preheated in an infrared oven to remove low molecular weight fractions.
