Abstract: In embodiments, a CPR chest compression system includes a retention structure that can retain the patient's body, and a compression mechanism that can perform automatically CPR compressions and releases to the patient's chest. The compression mechanism can pause the performing of the CPR compressions for a short time, so that an attendant can check the patient. The CPR system can include a user interface that can output a human-perceptible check patient prompt, to alert an attendant to check the patient during the pause. The compression mechanism can during a CPR session retreat a distance away from the patient's chest whereby the patient's chest can expand without active decompression of the patient's chest beyond the chest's natural resting position.

Abstract: Polysaccharide fibers are produced by hot extrusion of a gelling polysaccharide into air or a gelling salt bath. Optionally, other polysaccharides, including non-gelling types, may be co-extruded with the gelling polysaccharide. The fibers are useful for the production of wound dressings and catamenial devices, and many other devices.

Abstract: Cement compositions, i.e., mortar, structured concrete, pre-cast concrete, and oilfield cement, comprising 0.01-0.9% (wt/wt) welan gum are described.

Abstract: Low viscosity welan gum having a 5% (wt.) aqueous solution viscosity of 100 cP and process for preparation of such are described.

Abstract: Low viscosity heteropolysaccharides, e.g., xanthan gum, S-194, and guar gum, are disclosed. These gums are especially useful in preparing herbicidal compositions.

Abstract: Low viscosity heteropolysaccharides, e.g., zanthan gum, S-194, and guar gum, are disclosed. These gums are especially useful in preparing herbicidal compositions.

Abstract: Bipyridinium quaternary salt compositions are prepared which are dry, free-flowing, wettable powders. The solid compositions are complexes of the bipyridinium salts and algin.

Abstract: An aqueous slurry containing ground coal and a biosynthetic polysaccharide is disclosed.

Abstract: Water-based paints exhibiting improved stability and application properties are obtained by adding to 100 gallons (379 liters) of paint from 1 to 7 pounds (0.45 to 3.2 kg) of Heteropolysaccharide S-156.

Abstract: Texturized wall coverings comprising inexpensive materials such as paper pulp fibers, textile linters, and cotton threads can be made water resistant by the incorporation therein of a blend of tamarind gum, algin, and, optionally, guar gum.

Abstract: High concentration polymer slurries contain up to 65 weight % xanthan gum in a hydrophobic solvent base treated with suspending agents, dispersants, and thinning agents. Mineral oil, diesel oil, kerosene, alcohols (six to twelve carbons), vegetable oil, ester-alcohols, polyol ethers, and the like may be used as the solvent. The preferred suspending agent is either an organophilic clay or hydroxypropyl cellulose. The preferred dispersant is either an ethoxylated linear alcohol or a fatty acid ester of vegetable oil or animal oil. The preferred thinning agent is lecithin. These slurries greatly improve the dispersibility of xanthan gum or any other hydrophilic colloid, such as guar, hydroxypropyl guar, cellulosics, polyacrylamides, and the like.

Abstract: Sodium cellulose sulfate can be used alone, or in combination with other natural or synthetic gums, as thickening agents for fabric printing paste compositions containing acid dyes. The printing paste is applied in the usual manner, and then the printed goods are heated. The sodium cellulose sulfate content of the paste, upon heating, fixes the acid dye on the printed goods, thereby eliminating the necessity of using acid or acid salts in printing pastes.

Abstract: Thickened latex coatings with improved properties are obtained by adding to 100 gallons (379 liters) of paint from 1 to 8 lbs. (0.45 to 3.6 kg) of a composition comprising Heteropolysaccharide S-10 and a copolymer of an alkenyl aromatic monomer and an unsaturated acid anhydride.
