Abstract: This invention is directed to fabric finishes or treatment preparations for nylon, polyester, and other textile and fibrous substrate materials that will render them hydrophilic. The finishes of the invention are comprised primarily of polymers that contain carboxyl groups, salts of carboxyl groups, or moieties that can be converted to carboxyl groups by some chemical reaction.

Abstract: A composition is formed by compounding a first substance with a second substance. The first substance includes a bicarbonate, an acid or a combination thereof. The second substance includes a frothing agent, a coating agent or a combination thereof. The composition may be formed into coated particles or a mass of particles coated by a matrix, such as a matrix of the frothing agent. The particles or mass of particles may have more than one coating. The compound is used for preparing a stable froth on a beverage, such as a hot cup of cappuccino. The frothing agent may include not only compounds that enhance the stability of the foam but also compounds that enhance other characteristics of a desirable froth. The coating agent may be used to delay the reaction between a bicarbonate and an acid when the compound is added to water, such that a large volume of froth is produce, but undesirable flocculation, turbidity and increases in viscosity are avoided.

Abstract: The present invention is directed to modified polyamines and to compositions comprising one or more modified polyamines as the main odor absorbing ingredient(s) for use in odor absorbing or deodorizing personal care products. The invention is further directed to personal care products with deodorizing properties using the disclosed compositions and to methods of making and using the compositions and products.

Abstract: A molded component or article for biomedical use is prepared from a crosslinkable non-water-soluble polymer which when crosslinked and saturated with water forms a hydrogel. The polymer is formulated as a composition containing a non-aqueous diluent in addition to the polymer, the diluent being present in a volumetric proportion that is substantially equal to the volumetric proportion of water in the hydrogel that would be formed when the polymer is crosslinked and saturated with water. The composition is cast in a mold where the composition is exposed to conditions that cause crosslinking to occur by a reaction to which the non-aqueous diluent is inert. The crosslinking reaction produces a molded non-aqueous gel which is then converted to a hydrogel by substituting an aqueous liquid such as water or physiological saline for the non-aqueous diluent.

Abstract: Computer processing of order data received at a computer system in connection with the sale and purchase of debt instruments in a primary market includes automatically adjusting an order size based on a investor-specified demand curve for a debt instrument and a market value that established subsequent to the receipt of the purchase order. The demand quantity can be specified by a collection of discrete data sets, each including a market value and a demand quantity at that market value. A dynamically updated order book that aggregates the received orders to distinguish demand for the debt instrument at different market values can be displayed to an issuer and used to establish the market value of the debt instrument. The order book may be updated upon request during a subscription period for the debt instrument to enable access to an updated status of orders placed for the issue. Purchases may be automatically transacted using swaps to satisfy payment obligations for received allocations of the new issue.

Abstract: Microporous or open ultrafiltration poly (tetrafluoroethylene-co-perfluoro-(alkyl vinyl ether)) (PFA) or poly (tetrafluoroethylene-co-hexafluoropropylene) (FEP) film membrane or hollow fibers having open pores are formed from a melt blend of 10 to 35 weight percent of the PFA or FEP and a chlorotrifluoroethylene oligomer solvent. The melt blend is shaped and one or more surfaces of the shaped melt blend are coated with the solvent prior to phase separation of the melt blend. Coating the membrane with solvent during shaping results in membrane having larger pores on that membrane surface as compared to membranes not coated with solvent. The shaped melt blend is cooled to effect phase separation and crystallization of the PFA or FEP from the blend. The solvent is separated from the PFA or FEP by extraction and the porous PFA or FEP is heat set under restraint to prevent shrinkage.
