Title: Method for frequency domain seismic data processing on a massively parallel computer
Inventor: MAHER LOUIS J
IPC: G06F15/80
Filed: 1996-06-13
Abstract: A frequency domain method (figures 3A & 3B) of processing geophysical data on a computer (18) having massively parallel processors (2). The method involves assigning data slice partitions to each processor (46), precomputing a velocity model corresponding to the geophysical data (72), and migrating the data on each slice within each processor using a one-pass, split wave equation finite difference technique for depth migration (50, 54) and either phase shift (230) or recursive techniques for time migration. A sequence of transforms and stranspositions (160) between processors assigned partitions on each frequency slice transforms into the frequency-wavenumber domain and allows the migration calculations to be directly performed by each processor to be independent of each other processor. The transforms and transposes also allow for depth migration error correction and filtering (184) in the frequency-wavenumber domain.

Title: Method of producing light alloy wheels
Inventor: SHCHERBA VALERY NIKOLAEVICH
IPC: B21K1/28
Filed: 1996-11-12
Abstract: The proposed method of producing light alloy wheels involves producing the wheel rim from a shaped section obtained by extrusion of an initial blank. The section is bent into a ring and butt-welded. A wheel disc is then fitted and joined to the rim. Depending on the desired degree of homogeneity in the structure of the material and the physical and mechanical characteristics of the section, the latter is produced by extrusion of a pre-heated blank in the absence of resisting friction or in the presence of regulated compression forces in the surface layers of the article by selecting the appropriate heating regime for the article and capsule and the appropriate kinematic regime of movement of the capsule and die. In order to obtain a section with a homogeneous structure free of coarse crystalline borders and shrinkage under mechanical treatment and enhanced physical and mechanical characteristics, extrusion is carried out by the method of friction-assisted extrusion. The section is bent into a wheel on section bending machines and after buttwelding the rim is corrected. The wheel disc is produced by casting or stamping from a solid or sheet blank. The disc and rim are fitted together by pressing and subsequent welding.

Title: Method and device for plastic lamination of metal strip by means of direct extrusion
Inventor: PICKER EBERHARD
IPC: B29C48/08
Filed: 1998-04-27
Abstract: In this method for plastic lamination of a metal strip by means of direct extrusion, in which the metal strip is moved in its longitudinal direction, and is heated; by means of a sheet die, a film of molten, thermoplastic plastic material is deposited directly onto one side of the moving metal strip, this plastic film is pressed onto the metal strip, while being led through a gap between two rollers,  by which the roller adjacent to the plastic film (laminator roller) is maintained below the melting temperature of the plastic material; if necessary the other side of the metal strip may be coated with a plastic film in similar fashion.  While laminating a steel strip, the latter is heated to such a temperature that it has a temperature, in the depositing region of the liquid plastic film, which is above the melting point of the respective plastic material. Between the roller (laminator roller) which is pressing on the plastic film or a continuous belt (laminator belt) which is pressing on the plastic film, surface contact is made and this surface is maintained by synchronous moving-on of the surfaces of the plastic film and the laminator roller or laminator belt, which are in contact, via a contact time or contact length which suffice, at a belt rate of at least 50 m/min and a cooling rate of at most 400 W/m2 °C, to cool down the surface layer of the plastic film to a temperature of at least approx. 20°C below the melting point of the respective plastic, before contact the plastic film and the laminator roller or laminator belt is lost.  In a subsequent treatment, the laminated metal strip is heated to a temperature in the region of the melting point and finally cooled rapidly to a temperature below 40_C.

Abstract: A process for producing a frozen fat-free chopped and formed potato product. The process entails peeling potatoes, cutting the peeled potatoes into potato pieces, and blanching the cut pieces. The cut pieces are then partially blended to produce a mixture of potato bits and paste. A hydrocolloid fat substitute, such as a cultured skim milk powder stabilized with additional hydrocolloids, is introduced to the partially blended potato mixture, preferably at a level of 2 to 5% by weight. The potato pieces and hydrocolloid fat substitute are then further blended, and are then extruded into a formed fat substituted potato product. The formed potato product is then dusted with a wheat flour, precaramelized saccharide, annatto, and seasoning powder composition. The dusted formed fat substituted potato product is then prebaked to form a crust on the product, which subsequently may be frozen and packaged for storage, transport and sale. The product may then be baked to produce a fat-free product having good organoleptic properties, a crisp crust, and exterior flavor and texture that are similar to conventional fat-containing chopped and formed potato product.

Title: Method and device for determining correction parameters
Inventor: DITTRICH FRANK
IPC: G01C21/28
Filed: 1998-02-05
Abstract: The invention relates to a method for determining correction parameters for the measured values of a magnetic compass, which is built into a land craft for navigation purposes, and gives the azimuth a of the direction of motion of the vehicle; of a gradiometer giving the elevation e of the direction of motion of the vehicle in relation to the horizon; and of an odometer, giving the distance s travelled.      In this method, two visually navigated test drives are carried out in different directions between known point of departure and arrival. The measured values (a, e, s) are replaced by corrected values (a', e', s') in accordance with the following: a' = a + A + B . sin a +  C . cos a; e' = e - A2; S' = p. The correction parameters are determined by performing a vectorial comparison of the known direction and distance values (a', e', s') with the measured values. The correction parameters are as follows: A for declination and compass mounting errors in azimuth; B, C for hard and soft magnetic vehicle magnetism; A2 for mounting errors of the gradiometer in elevation; and p for a scale error of the odometer.
