Publication number: 20130323614Abstract: Gas Stream Production The present invention provides a method for the production of carbon dioxide and/or hydrogen gas streams, the method comprising: (i) thermally treating a feedstock material to produce a syngas comprising carbon monoxide and hydrogen and plasma-treating the syngas in a plasma treatment unit; (ii) reacting the plasma-treated syngas with water in a further treatment unit, whereby at least some of the carbon monoxide is converted into carbon dioxide; and (iii) recovering hydrogen and/or, separately, carbon dioxide from the syngas.Type: ApplicationFiled: January 6, 2012Publication date: December 5, 2013Applicant: ADVANCED PLASMA POWER LIMITEDInventors: Chris Chapman, Rolf Stein, Martin Brooks, Edward S. Manukian, Robert M. Clark

Publication number: 20080179777Abstract: A polyolefin-containing material including an internal additive, where the internal additive is a triglyceride according to the structure (T): CH2(OR1)—CH(OR2)—CH2(OR3) ??(T) where R1, R2 and R3 are, independently of one another, saturated, mono- or poly-olefinically unsaturated acyl groups containing 8 to 24 carbon atoms, the chain lengths of the acyl groups are the same or different, and the polyolefin-containing material exhibits improved softness is provided. A process for the softening finishing of articles including polyolefins is also provided and includes adding a triglyceride to polymer granules including a polyolefin present in an amount of from about 0.1% to about 40% by weight, based on the weight of the granules, and subjecting to further processing to form a fiber or film.Type: ApplicationFiled: March 31, 2008Publication date: July 31, 2008Inventors: Christine Wild, Rolf Stein, Hans-Georg Kraemer

Publication number: 20070166221Abstract: Despite intensive research and numerous essays and reports, chemical and physical methods of producing fullerene structures of carbon modifications could heretofore only be carried out on a laboratory scale. The invention suggest a new family of nanomaterials, more specifically of carbon hybrids, namely nanostructured carbon fullerenes (NCF). Methods of production and methods of use thereof are being proposed and illustrated using numerous examples. The proposed NCF and their nanocompounds are very well suited for industrial production and in particular in highly technological applications.Type: ApplicationFiled: January 14, 2005Publication date: July 19, 2007Inventors: Christian Schonefeld, Rolf Stein, Volodymyr Padalko, Gunther Mathar

Patent number: 4497193Abstract: A gripping head (1) comprises a plurality of vertical, spaced laminae (3) defining a gripping aperture (4) for gripping a sheet (7) to be stretched. The laminae (3) are welded at one edge to flanges of a horizontal cross member. In order to facilitate the welding, and to reduce the stress concentration factor at the weld, fillers (11) are arranged between the laminae at the said edge and the weld is a butt weld (13). After welding, the ends of the fillers (11) at the weld seam (13) are bored out (18) to remove cracks, or gaps (16, 17) between the fillers (11) and the laminae (3).Type: GrantFiled: March 22, 1982Date of Patent: February 5, 1985Assignee: SMS Schloemann-Siemag AktiengesellschaftInventors: Heinrich Kutz, Dietrich Grube, Georg Eggert, Rolf Stein
