Abstract: A hydraulically entangled nonwoven composite structure that includes a matrix of substantially continuous filaments; and recycled synthetic fibers and fiber-like materials having at least one thread element composed of synthetic material with at least one irregular distortion generated by hydraulic fracture of the thread element to separate it from a bonded fibrous material while the bonded fibrous material is suspended in a liquid. This nonwoven composite structure may be used as a wiper or an absorbent material.

Abstract: A process for treating a fibrous material which includes the steps of: 1) providing a liquid suspension composed of fibrous material; 2) intermixing the liquid suspension of fibrous material with a treatment over a time period T1—wherein the treatment requires a period of time TR sufficient to treat the fibrous material; 3) depositing the liquid suspension of fibrous material and intermixed treatment onto a forming surface to form a layer and removing a substantial portion of the liquid, over a perod of time T2; and 4) applying pressurized jets of a liquid to the layer of fibrous material to wash unused treatment from the fibrous material within a period of time T3. Periods of time T1, T2 and T3 are immediately consecutive and amount to a total period of time at least as great as TR.

Abstract: A flame retardant composition for treating a high pulp content nonwoven web is provided. The flame retardant composition includes soluble solids formed from inorganic salts, such as ammonium polyphosphate and sulfur. The TGA range of such soluble solids is from about 175.degree. C. to about 370.degree. C. The flame retardant composition may be continuously and uniformly applied to the high pulp content nonwoven web by a non-compressive process.

Abstract: A method of making a nonwoven composite material. The method includes the steps of: providing a hydraulically entangled web containing a fibrous component and a nonwoven layer of substantially continuous filaments; applying a bonding material to at least one side of said web; and creping said at least one side of the hydraulically entangled web. The bonder material may be an aqueous mixture including a curable latex polymer, a pigment, and a cure promoter. Also disclosed is a nonwoven composite material made of a hydraulically entangled web including a fibrous component; a nonwoven layer of substantially continuous filaments; and regions containing bonder material covering at least a portion of at least one side of the composite material, wherein at least one side of the web has been creped.

Abstract: A process for treating a fibrous material which includes the steps of: 1) providing a liquid suspension composed of fibrous material; 2) intermixing the liquid suspension of fibrous material with a treatment over a time period T.sub.1 --wherein the treatment requires a period of time T.sub.R sufficient to treat the fibrous material; 3) depositing the liquid suspension of fibrous material and intermixed treatment onto a forming surface to form a layer and removing a substantial portion of the liquid, over a period of time T.sub.2 ; and 4) applying pressurized jets of a liquid to the layer of fibrous material to wash unused treatment from the fibrous material within a period of time T.sub.3. Periods of time T.sub.1, T.sub.2 and T.sub.3 are immediately consecutive and amount to a total period of time at least as great as T.sub.R.

Abstract: 2,8-Disubstituted quinazolinones are prepared by first subjecting the quinazolinone basic skeleton to condensation by customary reactions and then introducing the desired substituents into the 8-position. The compounds are suitable as active compounds in medicaments, in particular for the treatment of inflammations, thromboembolic diseases and cardiovascular diseases.

Abstract: An inpavement light fixture for mounting in an airport runway or a taxiway having a cover with a flat surface and one or two windows for the passage of a light beam. An optical prism is detachably mounted in a cavity formed in the cover beside and beneath each window. The prism has three flat sides forming an equilateral triangle with two of the sides sloping upwardly to a top edge positioned at a top of its window. A special sealing member fits over the prism and preferably covers one of the two sides which slope upwardly. This member extends about a lower portion of the prism and forms a water tight seal. An electric light is mounted in a bottom receptacle on which the cover is supported. A light channel is formed in the top of the cover and extends from each window towards an edge of the cover. This channel has a bottom which slopes at a small angle to the flat top.

Abstract: A heat exchanger (18) located in an enlarged flow area section (10) of a duct (12) includes a plate (14) located downstream of the exchanger for improving distribution of the duct flow.

Abstract: A disposable surgical gown is disclosed having a body portion and two side panels. Interior tie strings secure the gown to the wearer's body and the back is closed through mating fastening means on each side panel. The side panels are brought together to engage the fastening means through pull tabs overlaying the fastening means on the overlapping side panel. The pull tabs are removable from the side panel after use, thereby eliminating any contact with the gown itself in putting the gown on for retention of sterility of the gown.

Abstract: Coherent strands are made from a dispersion of asbestos fibres in an aqueous soap solution containing up to 100 percent molar excess of fatty acid, by a process including the steps of forming a stream of dispersion and chilling the newly formed stream sufficiently to gel the dispersion.
