Abstract: Methods of forming composite rovings formed of reinforcing fibers coated with at least one matrix resin are provided. The matrix resin may be any thermoplastic or thermoset powder or thermoplastic or thermoset emulsion, and is applied to reinforcement fibers after a size composition has been applied. The matrix resin may be applied to the reinforcing fiber in an amount from about 20 to about 35% by weight of the composite fiber. The fibers travel a distance sufficient to dry the size and the matrix resin. In exemplary embodiments, the distance may be from about 20 to about 150 feet. A heating apparatus may be utilized to assist in drying the fibers. The end composite fiber product is a composite roving that is formed in one step during the glass forming process and can be used in further processing steps to form composite parts without the need to add additional resin.

Abstract: A dishwasher tub includes a main body having opposing side walls that are interconnected by a rear wall, all formed from a multi-layered composite material. A cap member is joined atop the opposing side and rear walls, a base member is joined to lower edge portions of the opposing side walls and rear wall, and a frontal halo member is mounted between the cap and base member to define an overall washing chamber having a front opening. Preferably, the multi-layered composite material includes an inner stainless layer, a rigid layer and an outer protective layer, such as a layer of stainless steel, a rigid polyester mat, and a protective layer of hard plastic or aluminum foil. The outer layer also preferably serves as a shipping container for the dishwasher, enabling components of the dishwasher to be transported to a designated location for final assembly.

Abstract: The present invention provides for a roof ridge ventilator cover that is adapted to be removably secured to a conventional roof ridge ventilator. The roof ridge ventilator cover of the present invention, when installed on a conventional roof ridge ventilator, will cover and block the air vents of the ventilator. The roof ridge ventilator cover generally includes two panels serving to cover and block the two panels of air louvers or vents of the roof ridge ventilator. The roof ridge ventilator cover may be made from sheet aluminum or other sheet material, including sheet made of plastic, having sufficient resilience to return unaided to a formed shape after some deflection. The roof ridge ventilator cover is installed by deflecting the cover sufficiently so the cover may be placed over the top portion of the roof ridge ventilator.

Abstract: The invention relates to a mixture of a polyphenylene ether resin and a styrene-containing polymer or copolymer, in which at least a part of the polyphenylene ether resin is modified with reactive groups of a first type and at least a part of the styrene-containing polymer or copolymer is modified with reactive groups of a second type which are capable of reacting with the reactive groups of the first type. The invention further relates to articles formed from the said mixture, which have a good combination of low surface gloss and mechanical properties.
