Abstract: The invention relates to a method for obtaining cellulose by separating lignin from a biomass comprising lignocellulose in the form of plants or plant parts, wherein the biomass comprising lignocellulose is solubilized in a boiler in an alkaline medium comprising alkanol amine, and dissolved lignin is separated from the resulting raw cellulose. Said method is characterized in that the biomass comprising lignocellulose is not from a wood source, and is solubilized at a temperature of less than approximately 170° C. in a solubilizing agent based on alkanol amine and water, wherein the weight ratio of alkanol amine to water is set to 80:20 to 20:80, and raw cellulose thus produced is separated from the waste lye using a typical method. Said method is particularly advantageous for obtaining cellulose from annual plants, particularly wheat straw. The method is advantageously improved in that the solubilization takes place in the presence of a catalyst, particularly of anthrachinon.

Abstract: A method of making an electrical stimulation lead includes disposing conductive contacts in a spaced-apart longitudinal arrangement within a mold. A portion of a stylet tube is disposed within the mold, and the stylet tube extends through the conductive contacts. Conductive wires are positioned external to the stylet tube and each contact is coupled to at least one of the wires. A non-conductive material is molded between adjacent pairs of the contacts, around the wires, and over the stylet tube, to form a portion of the lead. This portion includes the contacts, the stylet tube, the wires, and one or more non-conductive spacers formed from the non-conductive material. Finally, the portion of the lead is removed from the mold. Another method includes placing a temporary tube around the conductive contacts and forming spacers by introducing flowable, curable, non-conductive material within the tube and between the conductive contacts.

Abstract: A method and assembly for separating contaminants from liquids, such as condensates, or vapors at an evaporation plant. The contaminants are separated from liquids by stripping when bringing a contaminant-enriched liquid into direct contact with a vapor by spraying or distributing the liquid into the vapor flowing in a vapor duct or onto wall surfaces in the vapor duct thus reducing the contaminant-content of the sprayed liquid and producing a cleaner liquid. The contaminants are enriched in the vapor. From vapors contaminants are separated by absorption when bringing a contaminant-enriched vapor into direct contact with a cleaner liquid by spraying or distributing the liquid into the vapor flowing in a vapor duct or onto wall surfaces in the vapor duct thus increasing the contaminant-content of the liquid, but producing a cleaned vapor.
