Title: Process for preparing tenside mixtures based on ether sulphonates and use of said tenside mixtures
Inventor: WUEST WILLI
IPC: C09K23/02
Filed: 1990-05-28
Abstract: ABSTRACT     In a process for preparing tenside mixtures based on alkyl ether sulphonates or their salts (ether sulphonates) as the main component and which are particularly suitable for use in tertiary crude oil extraction, alkyl ether sulphates are reacted with an aqueous solution of an alkali sulphate at temperatures of 160°C to 220°C.  To prepare admixtures of the ether sulphonates based on alkoxylated alcohols of natural and/or synthetic origin and which are essentially free from sulphate salts, not more than approximately equal quantities of the alkoxylated alcohols are reacted in aqueous medium of weakly alkaline pH with a stoichiometric excess of alkali sulphate and, if necessary, allowed to further react, preferably under the specified reaction conditions.  The resultant tenside mixture is then extracted with at least essentially water-insoluble alcohols at lower, but still high, temperatures.  The tenside mixtures obtained can be used, in particular admixed with residual alcohol from the extraction stage, for tertiary crude oil extraction.

Title: Method for parsing images
Inventor: JAGADISH HOSAGRAHAR V
IPC: G06F17/27
Filed: 1992-06-11
Abstract: A METHOD FOR PARSING IMAGES Abstract Parsing of partially orderable sets of symbols is achieved by first forming a total order of the given terminal symbols. The relationships between the terminal symbols are formulated, and the given grammar is broken up into a set of production rules. Based on the production rules, a determination is made as to what kind of symbol is needed to comply with the given grammar. This determination encompasses both the type of terminal symbol that is to be found as well as the partial order relationships that such a symbol must have. The set of totally ordered symbols are searched, in order, and the first symbol that meets the specified criteria is selected. When appropriate, the symbols retrieved from the totally ordered set are reduced to non-terminal symbols, with the ultimate goal being the inclusion of all of the symbols in the totally ordered set within one reduced non-terminal symbol.
