  • Patent number: 6905985
    Abstract: A fabric cartridge for an automotive beating and cooling system. The apparatus includes: a cartridge assembly, the cartridge assembly including a housing; and a single-ply, die cut fabric web disposed therein. In the preferred embodiment, the fabric web includes: a float-free fabric substrate; at least one surface including a laminated film; and a plurality of apertures for diverting airflow in the heating and cooling system; and a noise/friction reduction agent for reducing the interaction between the housing and the fabric web.

  • Patent number: 5124519
    Abstract: A microwave susceptor composite which includes a first layer of polymeric fibrous material, and a second layer of thermoplastic polymer material having microwave susceptive characteristics. The polymeric susceptor and polymeric fibrous material layers are arranged in lamina surface-to-surface contact and bonded into an integral structure by application of heat and pressure. A uniform composite material is obtained by carding the polymeric fibrous materials prior to bonding the first and second layers. In microwave cooking applications the fibrous layer of the composite absorbs excess effluents from the food product. Browning and crisping of food products is effected by microwave excitation of the metallized second layer of the composite.

  • Patent number: 4671266
    Abstract: A blister bandage comprising at least one ply of an aerated latex microsized hydroentangled fabric, having an adhesive disposed on at least one surface of said fabric. The present invention has sufficient hydrophobicity in the fabric to be a barrier to liquid borne bacteria while preserving comfort, air permeability, and flexibility therein. In addition to the above properties, the bandage is sterilizable and will keep the skin beneath the bandage dry.

  • Patent number: 4265790
    Abstract: Dry blended carbonate or phosphate-based laundry detergents are prepared by adding to unhydrated or partially hydrated builder salts, a pH buffering compound and a detergent active compound, together with other formulating agents, coarse, hydrous granular water soluble silicate particles, the silicate particles passing a 10 mesh screen and about 95% of the particles are retained on a 100 mesh screen, according to the disclosed method. Dry blended laundry detergents so formulated are substantially completely free of insoluble product lumps when used in cold wash water in the temperature range of 35.degree.-75.degree. F.
