  • Patent number: 5409574
    Abstract: In accordance with the present invention, there is provided herein improved glass fiber dispersions for making uniform glass fiber mats by the wet-laid process. The well dispersed glass fiber compositions of this invention usually are prepared by mixing chopped glass fiber bundles in water with a small amount of a propoxylated fatty amine ethoxylate surfactant to disperse the bundles into individual fibers. As a feature of the invention, the dispersions may be formed at relatively high glass fiber consistencies. The resultant dispersions are characterized by low foaming and can be used to make very high quality glass fiber mats at high rates of production.

  • Patent number: 5407536
    Abstract: In accordance with the present invention, there is provided herein improved glass fiber dispersions for making uniform glass fiber mats by the wet-laid process. The well dispersed glass fiber compositions of this invention usually are prepared by mixing chopped glass fiber bundles in water with a small amount of an alkylamidoalkyl sultaine surfactant to disperse the bundles into individual fibers. As a feature of the invention, the dispersions may be formed at relatively high glass fiber consistencies. The resultant dispersions then are used to make very high quality glass fiber mats at high rates of production.

  • Patent number: 5380542
    Abstract: A cereal or grain hydrolysate-containing composition which is derived from the enzymatic, e.g., amylase, hydrolysis of cereal or grain in combination with a hydrocolloid, preferably carrageenan or a blend of xanthan gum and locust bean gum, can be effectively used as a fat mimic in preparing low fat comminuted meat products. Thermo-irreversible gels useful for providing non-fat fat mimics can also be prepared in accordance with the invention. In addition to amylase, the enzyme used for the hydrolysis of the cereal/grain substrate can be selected from the group consisting of amyloglucosidases (.alpha. -1,4-glucan glucohydrolase), cellulases (.beta. -1,4-glucanohydrolase), pullulanases (pullulane 6-glucanohydrolase), cyclodextrine glycosyltransferase (.alpha. -1,4-glucan-4-glycosyltransferase), proteases and mixtures thereof.

  • Patent number: 5300665
    Abstract: Fatty acid esters of hydroxyalkylsulfonates and fatty acid amides of aminoalkylsulfonates are prepared by heating an excess of the fatty acids with the sulfonate until the water of condensation is removed. The excess fatty acid is removed by distillation and the isolated fatty acid ester or amide product is directly and rapidly cooled to minimize decomposition and color degradation.

  • Patent number: 5120561
    Abstract: The invention provides a food additive prepared from refined and fractionated phospholipids containing at least 35% phosphatidyl choline and a ratio of 2:1 to 10:1 phosphatidyl choline to phosphatidyl ethanolamine which is complexed with water and vigorously mixed to form globular vesicles or liposomes. The aqueous liposomes are then used per se or mixed with food ingredients and/or with an edible reinforcing carbohydrate to form a suspension or paste which is added to the foodstuff. The liposome can replace some or all of the fat in the food as well as acting as a carrier, encapsulating agent, moisturizing agent, and depanner for foods.

  • Patent number: 4999066
    Abstract: A fast-setting magnesium phosphate one-component adhesive/grout is used to bond tiles, e.g. ceramic tiles, to a substrate, e.g. sheet-rock. The grout comprises an activator prepared by e.g., mixing diatomaceous earth with at least a sufficient amount of an ammonium phosphate solution to form a paste then heating the paste to coat the pores of the diatomaceous earth and result in a dry solid which is then milled to yield the activator, magnesium oxide, diammonium phosphate, boric acid, and sufficient water to form a paste. This grout is applied to the surfaces to be bonded which are then brought together to form a composite which is allowed to set at ambient temperatures forming a durable bond in about three hours.

  • Patent number: 4954450
    Abstract: Disclosed is a method of growing a mixture of two or more species of lactic acid producing bacteria whose growth rates are differently affected by the pH of the nutrient growth medium. The method involves maintaining the pH of the medium at a low level which actively selects for the growth of one species until that species has reached the desired concentration. The pH is then raised to a level that actively selects for the growth of another species and maintained at this level until that species has reached the desired concentration. The method is especially useful for preparing a starter culture for Italian type cheese containing a mixture of coccus and rod bacteria because the ratio of these bacteria, one to the other, can be closely controlled.
