Abstract: A high-opacity cellulose-free synthetic paper is formed from a wet-laid nonwoven web of thermoplastic fibers, all or most of which fibers are made of a predetermined polymeric material. The wet-laid web is dried to remove excess water, drying being carried cut at temperatures below the melting temperature of the predetermined polymeric material. The dried nonwoven web is saturated on at least one side with a pigmented binder forming a continuous coating thereon. The binder is cured at temperatures below the melting temperature of the predetermined polymeric material.

Abstract: A gloss coating composition comprising radiation curable oligomers and monomers, and photosensitizers in a homogeneous mixture having a viscosity in the range of 4500 to 8000 cps; wherein the presence of the photosensitizers causes polymerization of the radiation curable oligomers and monomers when exposed to an ultraviolet light source. The coating composition is applied to at least one surface of a substrate and exposed to an ultraviolet light source resulting in curing of the composition onto the substrate surface without substantial penetration into the substrate surface forming a gloss coated substrate.

Abstract: An in-mold label material is a nonwoven mat of fibers having one side fused with the outer surface of a polymeric container and the other side coated with a pigment-containing latex suitable for printing thereon. The label paper is manufactured from commercially available fibers combined in water into a homogeneous mixture and then formed into a mat employing a wet-lay process. For use with polyethylene containers, the label may be a web consisting of 88-100% polyethylene fibers and 0-15% polyvinyl alcohol fibers or 70-100% polyethylene fibers, 0-15% polyvinyl alcohol fibers and 0-30% polypropylene fibers. For use with polyester containers, the label may be a web consisting of 50-90% polyester staple fibers, 10-40% bicomponent polyester/co-polyester, core/sheath binder fibers and 0-10% polyvinyl alcohol binder fibers thermally bonded together. The nonwoven web of fibers has a pigmented coating.

Abstract: A nonwoven composite web consists of 15 to 50 wt. % of first polyester fibers having a length of 5 mm to 3/4 inch and a denier of 0.3 to 3, 5 to 50 wt. % of second polyester fibers having a length of 5 mm to 1-1/2 inches and a denier of 3 to 15, and 10 to 40 wt. % of binder fibers comprising thermoplastic binder material having a melting temperature which is less than the first and second melting temperatures respectively. The first and second polyester fibers are bonded to each other at least in part by solidification of the thermoplastic binder material after subjecting the web to temperatures in excess of the melting temperature of the binder material but not in excess of the melting temperature of either the first or second polyester fibers. In particular, the web is thermally bonded by calendaring at a temperature of in the range of 360.degree. to 410.degree. F. and at a pressure in the range of 40 to 70 psi.

Abstract: A nonwoven composite web consists of 15 to 50 wt. % of first polyester fibers having a first length, a first denier and a first melting temperature; 15 to 50 wt. % of second polyester fibers having a second length, a second denier and a second melting temperature; 15 to 50 wt. % of third polyester fibers having a third length, a third denier and a third melting temperature; 10 to 35 wt. % of polypropylene fibers; and 1 to 25 wt. % of cellulose fibers. The first, second and third lengths are no less than 1/2 inch, the first, second and third denier are no less than 1.5, and the third melting temperature is less than the first and second melting temperatures respectively. The first and second polyester fibers, the polypropylene fibers and the cellulose fibers are bonded to each other at least in part by solidification of the third polyester fibers after subjecting the web to temperatures in excess of the third melting temperature but not in excess of the first and second melting temperatures.

Abstract: A fluid filter including a filter body having inlet and outlet passages communicating with an open ended chamber on opposite sides of a tapered seat area. A cupshaped fluid filter or strainer element is located in the chamber through the open end thereof and is adapted to be closely received in the seat area. A bonnet assembly covers the open end of the chamber, is threadedly mounted to the body and is comprised of a bonnet, a bonnet nut and biasing means. The biasing means is employed to exert a biasing force against the filter or strainer element to continuously urge it toward the seat area. At least the bonnet and bonnet nut are themselves interconnected in a manner that permits both rotational and limited axial movement therebetween. The disclosed structure facilitates access to the chamber and filter or strainer element without the necessity for removing the entire fluid filter structure from a service installation.

Abstract: A fluid strainer element capable of withstanding high differential pressures when used and which facilitates straining of fluid flowing through the continuous side wall and one end wall of the element. The strainer is generally cup-shaped and includes an inner cup-shaped support structure having staggered perforations extending through the surfaces thereof. An outer cup-shaped strainer structure constructed of wire mesh is closely received over the support structure with the open ends of the two structures being substantially coextensive with each other. An annular binding ring is closely received over the structure open ends and is rigidly affixed thereto. The mesh size of the straining structure may be varied as is desired and/or necessary for any use and normal fluid flow through the strainer is from outside to inside the element.
