Abstract: A separator cartridge comprises a support screen comprising a substantially rigid reinforced plastic cylinder including an inner first major surface and an outer second major surface, a first nonwoven polymer layer adhered to the inner first major surface of the support screen, a second nonwoven polymer layer adhered to the outer second major surface of the support screen, and a polymeric screen contacting and frictionally engaging the second nonwoven polymer layer, the polymeric screen including a hydrophobic coating.

Abstract: A heat set blow molding process comprises providing a plastic preform, thermally conditioning the preform to achieve a temperature profile across the wall of the preform wherein the inner surface of the preform is at a higher temperature than the outer surface of the preform, said temperature profile being within the molecular orientation temperature range of the plastic, heating the outer surface of the preform to increase the temperature of the outer surface of the preform by at least about 10° C., enclosing the preform in a hot mold, expanding the preform to form a container within the hot mold by introducing a blowing gas into the preform to induce biaxial orientation in the preform and force the preform into conforming contact with the hot mold, and maintaining the expanded preform in conforming contact with the hot mold for a time sufficient to induce crystallization of the plastic material and to allow for stress relaxation.

Abstract: A model truck having a mechanism driven by a reversible electric motor for selectively raising and lowering the front of the truck and the bed of the truck.

Abstract: A heavy oil remover comprises a hydrocarbon solvent, dipropylene glycol mono n-butyl ether, a volatility stabilizer, a salt of an alkyl aromatic sulfonic acid, a branched alcohol ethoxylate, an ethoxylated alkyl mercaptan, and water.

Abstract: A reflective telecentric lens which uses an on-axis type concave mirror in a pseudo-off-axis manner to avoid blockage of a portion of the field of view. The concave mirror used in a pseudo-off-axis manner permits the telecentric stop, imaging lens, and film or an electronic detector to be moved outside of the field of view.

Abstract: A composite male hose coupler comprising a metallic tail piece; an externally threaded male fitting; and means for affixing the tail piece to the male fitting; and a method of manufacture thereof, are disclosed. The metallic tail piece is formed of annealed brass tube stack and includes a first cylindrical portion and a second cylindrical portion joined together by a radially outwardly extending flange generally perpendicular to the longitudinal axes of the first and second cylindrical portions. The externally threaded male fitting is formed of machined brass stock and includes external threads on the outer surface and an annular lip for receiving the flange of the tail piece.

Abstract: A heavy oil remover comprises a hydrocarbon solvent, dipropylene glycol mono n-butyl ether, a salt of an alkyl aromatic sulfonic acid, a branched alcohol ethoxylate, an ethoxylated alkyl mercaptan, and water.

Abstract: A railing assembly including a top rail, a bottom support, a plurality of spaced apart hollow plastic balusters, and supporting brackets affixed to the facing surfaces of the top rail and bottom support for receiving the upper and lower ends of the baluster respectively. A reinforcing tube is employed for rigidizing the baluster.

Abstract: A reusable concentrate cartridge adapted to be supported by a diluting and dispensing container for combining at least two separate components of a multi-component system, the concentrate cartridge having a hollow cylindrical body and a hollow tube with a closure portion. The concentrate cartridge is caused to open by the rotating engagement of a closure cap on the diluting and dispensing container to which causes the closure portion of the hollow tube to disengage to release the concentrate material.

Abstract: A flame retardant composite sheathing including a core layer, having a plurality of superposed layers of a water-resistant paperboard adhered together by layers of an adhesive positioned intermediate and contacting adjacent said layers of water-resistant paperboard, a first layer of a polyolefin adhered to a major surface of the core layer, a metal foil adhered to the first layer of polyolefin, a second layer of a polyolefin adhered to the metal foil, and a layer of water resistant liner board adhered to the second layer of polyolefin.

Abstract: A lobby dust pan of the type generally having a receptacle portion pivotally connected to a yoke. The yoke is flexible and is connected to a shaft. The yoke is deformable to enable a latch thereon to be retained with or released from suitably disposed openings in the receptacle. A shaft in turn has a handle connected to the upper end, and the other end connected to the yoke. The yoke is provided with an array of spaced apart outwardly projections or teeth suitable for assisting in the removal of debris from the user's broom, brush, or the like.

Abstract: A co-layer stretch blow molding preform comprises an outer plastic preform and an inner plastic preform, wherein the inner plastic preform includes an infrared energy absorbing material which is absent from the outer plastic preform.

Abstract: An apparatus for cleaning roof gutters having a cleaning mechanism pivotally mounted to the distal end of a height adjustable supporting pole.

Abstract: A wheel adapter that adapts a conventional vehicle hub to a wheel having a large inward offset, thereby permitting the original wheel track of the vehicle to be changed to match the width of a railroad track so the tires of the vehicle will sit on the railroad track. The adapter locates the wheel to avoid contact with a brake caliper on the vehicle.

Abstract: A heavy oil remover comprises a hydrocarbon solvent, dipropylene glycol mono n-butyl ether, a volatility stabilizer, a salt of an alkyl aromatic sulfonic acid, a branched alcohol ethoxylate, an ethoxylated alkyl mercaptan, and water.

Abstract: A heavy oil remover comprises d-limonene, dipropylene glycol mono n-butyl ether, a salt of an alkyl aromatic sulfonic acid, a carboxylated anionic detergent, an ethoxylated tallow amine, a branched alcohol ethoxylate, an ethoxylated alkyl mercaptan, and water.
