Publication number: 20080093045Abstract: To produce products from metal, such as powders, foils, coatings and molded parts, such as pins, pipes or sheets, from metal in the form of a semifinished product (15), the metal of the semifinished product (15) is melted by an inductive magnetic field (12), atomized and allowed to solidify in a chamber (25) into a powder or sprayed onto a carrier and hardened on the carrier. The molten metal is supplied in a gas nozzle (10) which is made either as a Laval nozzle or as a Venturi nozzle, as a film (21) which is stabilized by gas flows (14), and is then atomized by other gas flows (13).Type: ApplicationFiled: June 16, 2005Publication date: April 24, 2008Inventors: Karl Rimmer, Gunther Schulz

Publication number: 20070215712Abstract: A method for atomizing liquid films to fine droplets (2), wherein the liquid (2) is discharged from an elongate slotted nozzle (3) in the shape of a straight film. The outlet opening of the slotted nozzle (3) is located inside a linear Venturi nozzle (5) in whose divergent section linear gas outlet openings (7) (Laval nozzles) are provided and impinged upon by gas (6). The negative pressure produced in the area of the Laval nozzles (7) draws in gas flows (4) from the gas chambers (1), located at both sides of the liquid film and delimited by the convergent section of the Venturi nozzle (5). Said gas flows stabilize the liquid film in such a manner that it is atomized to a tent-shaped cone of liquid droplets only after passage of the narrowest point of the Venturi nozzle (5).Type: ApplicationFiled: June 16, 2005Publication date: September 20, 2007Inventors: Karl Rimmer, Gunther Schulz

Patent number: 6895840Abstract: Water pump pliers consisting of two pincer parts crossing themselves in a connecting region, each consisting of a handle portion and a jaw wherein said pincer parts are movably connected in said connecting region in such a way that said first pincer can be displaced relative to the second pincer to adjust a jaw opening-width on the one hand, and that the pincer parts with jaws can reciprocally pivot on the other hand. A blocking means is provided in such a manner that further shifting of the first pincer part is blocked when the jaws stop against a workpiece to be gripped. A spring element is installed between the pincer parts in such a way that a releasing force from the spring, operating in the opening direction of the jaws, acts upon the pincer parts.Type: GrantFiled: October 24, 2002Date of Patent: May 24, 2005Inventors: Gunther Schulz, Bodo Nilles

Patent number: 6497165Abstract: A pair of water pump pliers, comprising two pincer parts crossing themselves in a connecting region, each consisting of a handle portion and a jaw, wherein the pincer parts are movably connected in the connecting region in such a manner that the first pincer can be displaced relative to the second pincer to adjust the jaw opening width. The pincer parts reciprocally pivot on the other hand, wherein a blocking mechanism is provided in such a manner that further shifting of the first pincer part is blocked when the jaws stop against a workpiece. Also, a spring element is installed between the handle is such a manner that a releasing force from the spring, operating in the jaws' opening direction, acts upon the pincer parts.Type: GrantFiled: May 3, 2000Date of Patent: December 24, 2002Assignee: Serenco Nederland BVInventors: Gunther Schulz, Bodo Nilles

Patent number: 6481638Abstract: A method and nozzle for producing fine powder by atomizing molten material with gas are provided. Molten material, in the form of a film, flows out of a molten material nozzle that has an essentially rectangular discharge cross-sectional area. Thereafter, the molten material, together with an atomizing gas, flows through an initially converging and then diverging gas nozzle that is in the form of a linear Laval nozzle, has an essentially rectangular cross-sectional area, and through which flow is laminar. Laminar accelerated gas flow stabilizes and simultaneously stretches the film of molten material in the converging portion of the Laval nozzle until the film of molten material, after passing the narrowest cross-sectional area of the Laval nozzle, is uniformly atomized over its entire length.Type: GrantFiled: June 16, 2000Date of Patent: November 19, 2002Inventor: Gunther Schulz

Patent number: 5370784Abstract: A process for electrolytic production of fine-grained, single-phase, metallic alloy powders, especially powders of intermetallic compounds as well as noble metal alloy powders, is described in which powdery metallic precipitates are galvanically produced on the cathode from an electrolytic precipitating bath known in the art, which contains in solution the metals to be precipitated, under electrolysis conditions causing a powder precipitation known in the art. For the production of alloy powders with defined properties, it is determined, first in preliminary tests by gradual increase of the cathode potential with otherwise constant process parameters, the minimum cathode potential at which single-phase alloy powders result and then the powder precipitation is potentiostatically performed in a cathode potential at or above the minimum for the single-phase alloy precipitation.Type: GrantFiled: June 25, 1993Date of Patent: December 6, 1994Assignee: Schott GlaswerkeInventors: Roland Kammel, Gunther Schulz, Andreas Specht, Christian Keidel, Uwe Landau
