Abstract: Organosilicone materials that are "density-matched" to the hydrocarbon medium also act as defoamers in hydrocarbon fuel, specifically as described herein for diesel fuel. Specifically these new defoamers can be described as cross-linked organopolysiloxane-polyoxyalkylenes. They have the characteristics of being slightly soluble or insoluble in water and hydrocarbon fuels. By changing the solvent and the method of dispersion, different particle size distributions are obtained.

Abstract: The present invention provides a fiber treatment emulsion composition which can make animal fibers (mainly wool) resistant to the shrinkage arising from water-based laundering. The composition forms a strong, solid film by reaction among the base material, crosslinker, and colloidal silica as the water evaporates. These effects are reinforced by binding between the functional groups present in the fiber and such functional groups as the aminoalkyl groups bonded in the organopolysiloxane base material, the silanol groups bonded in the colloidal silica, and the amino, epoxy, methacryloxy, or acryloxy groups bonded in the crosslinker.

Abstract: The present invention relates to the composition, preparation, and use of multi-layer composite films comprising a core layer of low gas permeable material, two intermediate layers sandwiching the core layer, and two outer layers sandwiching the two intermediate layers. The core layer provides the excellent oxygen barrier property, whereas the intermediate and outer layers protect the core layer so the oxygen permeability of the resulting multi-layer composite film becomes independent on relative humidity.

Abstract: The process of the present invention teaches a novel method of cleansing a silane coated substrate of excess vinyl benzaldehyde. The basic process comprises the step of rinsing the silane coated substrate in acid, prior to exposing the silane coated film to the beverage. Alternatively, the silane coated substrate may be washed with water after the silane coated substrate is rinsed in the acid. Another alternate method teaches repeating the acid wash and water rinse steps either with the same or a different acid.

Abstract: A composite films which exhibit low oxygen transmission rates. The film comprises a silane resin coated on a plastic substrate then cured by ultraviolet radiation. For the silane coating, this invention relies on a class of organosilicon compounds derived from 1) organohydrogensilanes or organohydrogensiloxanes and 2) propargyl esters of carboxylic acids containing a terminal aromatic hydrocarbon radical, where the carbopropynoxy group of the ester and the aromatic hydrocarbon radical are separated by at least two adjacent ethylenically unsaturated carbon atoms. If more than two of these carbon atoms are present they form a sequence of conjugated ethylenic double bonds which allows the polymer to cross-link upon exposure to ultraviolet radiation.

Abstract: A process is described by which numerous waste or by-product aqueous hydrochloric acid streams can be purified by contacting the aqueous hydrochloric acid with a polystyrenic based resin to remove silicon containing impurities and thereby allowing the hydrochloric acid to be re-used for various applications.

Abstract: The amino groups of an organopolysiloxane are reacted with an acrylic acid or ester compound to provide a fiber-treating composition which is almost completely free of yellowing, while at the same time being characterized by an excellent softness and smoothness.

Abstract: A treatment agent in which a base component and a crosslinking component contain silicon-bonded perfluoroalkyl groups and curing groups. The components are mutually soluble to homogeneity as a consequence, and this makes possible long-term storage of the mixture of the two components. Moreover, when this treatment agent is used on fibers, textiles, plastics, metals, or porous inorganics and cured, an excellent water repellency and oil repellency are generated because a uniform film is developed.

Abstract: A foldable intermediate bulk container with a preferred capacity of about 1000 liters, capable of being stacked both in its erected position and in its folded position, comprises a rectangular base (10), four walls (21, 22, 23, 24) and a lid (35, 36) which are all interconnected. Each wall is pivotally connected to the base (10), at least three of them at different heights from the support (17) of the base, ascending by at least one wall thickness. It is preferably adapted for liquid or free-flowing powder. The base (10) may incorporate the function of a pallet into the structure of the container and may include means for facilitating emptying the container. The container may use an inner pocket (20) for the liquid or powder.
