Publication number: 20200131280Abstract: A process for recovering an esterified cellulose ether from a reaction product mixture obtained from a reaction of (a) a cellulose ether with (b) an aliphatic monocarboxylic acid anhydride or a di- or tricarboxylic acid anhydride or a combination of an aliphatic monocarboxylic acid anhydride and a di- or tricarboxylic acid anhydride, comprises the steps of (i) contacting the reaction product mixture with an aqueous liquid and precipitating the esterified cellulose ether from the reaction product mixture, and (ii) isolating the precipitated esterified cellulose ether from the mixture obtained in step (i). Tackiness of the esterified cellulose ether can be reduced when a cellulose ether is added before or in step (i) to the reaction product mixture, to the aqueous liquid or a combination thereof.Type: ApplicationFiled: March 14, 2018Publication date: April 30, 2020Inventors: Oliver O.

Publication number: 20050243961Abstract: A fuel assembly for a boiling water reactor contains a plurality of fuel rods maintained laterally by spacers and surrounded by a fuel assembly case. The outer walls of a spacer are provided with projecting elements that maintain a minimum space between the outer surface of the spacer and the fuel assembly case, the opening span of a spacer being smaller than the internal width of the fuel assembly case. The fuel assembly is characterized in that the spacer is maintained in an off-center position by a force acting laterally thereon such that an external space located between an outer surface of the spacer associated with the outer surface of a central cell and the fuel assembly case is narrower than an internal gap opposite the external space and oriented towards the center or towards a control element disposed at the center.Type: ApplicationFiled: April 1, 2005Publication date: November 3, 2005Inventors: Peter Bucheit, Hans-Peter Fuchs, Matthias Rudolph

Patent number: 6852639Abstract: The present invention provides a processing method that changes the given and unfavorable surface contour of a material layer to a predetermined, more favorable surface contour at least along a selected radial direction of the workpiece. Due to the fact that the etch process included into the processing method affects the whole workpiece simultaneously, a high throughput is achievable and the etching method is easily applied in an industrial setting, for example for the mass production of semiconductor products.Type: GrantFiled: July 31, 2002Date of Patent: February 8, 2005Assignee: Infineon Technologies AGInventors: Matthias Rudolph, Jens Stolze, Thomas Morgenstern, Jana Haensel

Patent number: 6320925Abstract: A spacer of a fuel assembly having intersecting webs undergoes reduced longitudinal expansion as a result of corrosion during an operating period. The webs have intersection locations at which assembly gaps are provided. The assembly gaps have widths which correspond essentially, at most over a fraction of their total length, to the wall thickness of an intersecting web, but are wider in a remaining region. Since corrosion layers growing from an edge of an assembly gap toward the intersecting web cannot touch the web, no solid pressure, which could lead to longitudinal expansion, builds up.Type: GrantFiled: January 27, 1999Date of Patent: November 20, 2001Assignee: Siemens AktiengesellschaftInventors: Reiner Manzel, Werner Jahreiss, Norbert Schmidt, Josef Steven, Peter Dewes, Friedrich Garzarolli, Erhard Ortlieb, Franz-Josef Bökers, Matthias Rudolph
