Title: Process for producing welded steel pipes with a high degree of strength, ductility and deformability
Inventor: KNAUF GERHARD
IPC: C22C38/06
Filed: 2000-05-10
Abstract: The invention relates to a process for producing welded steel pipes with a high degree of strength, ductility and deformability, especially line pipes, according to the UOE-process. A pipe is molded cold from a TM-rolled sheet, welded together and sized to the desired diameter. Starting with a sheet consisting of a steel with (in wt.%): 0.02 to 0.20 % carbon, 0.05 to 0.50 % silicon, 0.50 to 2.50 %  manganese, 0.003 to 0.06 % aluminum, the remainder being iron with potentially other production-related impurities, the pipe is after welding and sizing being subjected to a heat treatment process at a temperature of 100-300 degrees Celsius and for a holding time that is adapted to the thickness of the pipe wall, with subsequent cooling with air or by forced cooling. The resulting pipe is resistant to aging and has a sufficiently integral deformation reserve against fracturing with the same high degree of strength, without exceeding the upper limit for the ratio of yield strength to tensile stress according to the current regulations for conventional steels.

Title: Fluxon injection into annular josephson junctions
Inventor: USTINOV ALEXEY V
IPC: H01L39/22
Filed: 2002-04-10
Abstract: A method and apparatus for inserting fluxons into an annular Josephson junction is disclosed. Fluxon injection according to the present invention is based on local current injection into one of the superconducting electrodes of the junction. By choosing an appropriate value for the injection current, which depends upon the;spacing between injecting leads among other factors, the residual fluxon pinning can be reduced to a very small level. Fluxon injection according to the present invention provides for fully controlling the trapping of individual fluxons in annular Josephson junctions and is reversible to a state of zero fluxons without heating the Josephson above its critical temperature. Fluxon injection according to the present invention can be used for preparing the working state of fluxon oscillators, clock references, radiation detectors, and shaped junctions that may be used as qubits for quantum computing.

Title: Constant flow vane pump
Inventor: LUTOSLAWSKI JAROSLAW
IPC: F04C14/22
Filed: 2001-06-29
Abstract: A variable capacity pump includes a housing and a rotatable rotor within the  housing. The rotor includes radial slots to accommodate slidable vanes or rotor blades, wherein the vanes are urged outwards by centrifugal force into  contact with the inner surface of a surrounding cam ring. The cam ring is surrounded on one end by a pressure chamber including a piston under hydraul ic pressure, and on the other end by a seated spring. By controlling the pressu re distributed to the pressure chamber, the position of the cam ring with respe ct to the rotor may be changed to automatically vary the displacement of the pu mp in response to a pressure differential across a restriction orifice, thereby  regulating the output flow to be constant over a defined speed range.</SDOAB >

IPC: D04H1/70
Filed: 2000-10-04
Abstract: A method and system for improving the appearance, covering ability and physical properties of woven fabrics by supporting the fabric which is to be treated on a foraminous surface, directing a plurality of columnar liquid streams in the form of oblique vanes against the fabric at an angle which is oblique to the warp direction of the cloth. The columnar streams impinge the cloth under pressure which is sufficient to penetrate and effect an enter-entangling of the fibers of the fabric, and the fabric which is thus treated is advanced under similar streams to treat substantially the entire surface of the fabric. The direction of the jets impinges on opposite sides of the fabric and they are oriented in a position which places them in direct opposition of one another.

Title: Drill bit and method for grinding a drill bit
Inventor: MUHLFRIEDEL DIETER
IPC: B23B51/02
Filed: 2000-11-11
Abstract: The invention relates to a drill bit (2), having main cutting edges (4a, 4b) which are connected together by a transversal cutting edge (6). An open surface (7) which extends into a flute (8) lies adjacent to each main cutting edge. The drill bit (2) is ground, in particular, during a continuous three-dimensional grinding process in such a way that the open surface (7) forms a continuous curved surface which follows a radius of curvature (R) running from the main cutting edge (4a) in the direction of the flute (8). The continuous grinding process, in comparison to a conventional two-stage process, produces an improved drill bit geometry which is devoid of ridges (16). The ridge-free configuration reduces the mechanical stress during drilling to a minimum.

Title: Process for refining silver bullion with gold separation
Inventor: VANHOUTTE DIRK
IPC: C01B21/48
Filed: 2001-01-17
Abstract: The present invention concerns a process for refining silver bullion, i.e. raw silver containing generally more than 90% silver besides Se, Pb, Au, Cu and platinum group metals (PGM) as main impurities. The process comprises the steps of:  optionally removing Se as gaseous SeO2 from the molten metallic phase by injecting air, which is preferably O2 enriched, into the metallic phase at a preferred bath temperature of 1000-1100°C; optionally slagging off the Pb by contacting the molten metallic phase with a silica and borax based flux at a preferred bath temperature of 1000-1150°C; granulating the molten metallic phase in water, thereby forming Ag rich granules; leaching the Ag rich granules with HNO3 at a temperature above 50°C, preferably in an O2 enriched atmosphere, followed by filtration, thereby separating an Au bearing residue from an Ag rich liquor;  heating the Ag rich liquor, thereby evaporating H2O and forming an AgNO3 bearing melt; maintaining the AgNO3 bearing melt at a temperature of 300-350°C for at least 15 minutes, thereby forming a mixture of a purified AgNO3 and of a denitration residue containing essentially all the PGM as oxides; separating the purified AgNO3 from the denitration residue. By this process, the many drawbacks of the classical electrolytic refining of silver are avoided.
Patent CA-2397032-A1 (CA)
Inventor: HERRMANN HENRY OTTO JR
IPC: H01H9/42
Filed: 2002-08-07
Abstract: Arcs are prevented as electrical connectors are unmated by including a long and a short contact in an electrical connector with both contacts being connected along the same line between an electrical source and a load. The short contact comprises the lower resistance path between the source and the load and so carries most of the current when the connectors are fully mated. An electronic component, such as an FET or a positive temperature coefficient resistor is connected to the long contact. As the short contact is disconnected, the electronic component initially carries sufficient current to prevent arcing at the short contact. Current through the electronic component decays rapidly so that when the long contact is subsequently disconnected, the electrical energy in the short contact is reduced below an arcing threshold.

Title: Gene recombination and hybrid protein development
Inventor: ARNOLD FRANCES H
IPC: G16B30/20
Filed: 2001-05-23
Abstract: The invention relates to improved methods for directed evolution of polymers , including directed evolution of nucleic acids and proteins. Specifically, th e methods of the invention include analytical methods for identifying "crossov er locations" in a polymer. Crossovers at these locations are less likely to disrupt desirable properties of the protein, such as stability or functionality. The invention further provides improved methods for directed evolution wherein the polymer is selectively recombined at the identified "crossover locations". Crossover disruption profiles can be used to identify  preferred crossover locations. Structural domains of a biopolymer can also b e identified and analyzed, and domains can be organized into schema. Schema disruption profiles can be calculated, for example based on conformational energy or interatomic distances, and these can be used to identify preferred  or candidate crossover locations. Computer systems for implementing analytic al methods of the invention are also provided.
