Title: Method of optimizing shim coil current selections in magnetic resonance magnets
Inventor: DORRI BIZHAN
IPC: A61B5/055
Filed: 1990-07-19
Abstract: RD-19,395 METHOD OF OPTIMIZING SHIM COIL CURRENT SELECTIONS IN MAGNETIC       RESONANCE MAGNETS     Abstract of the Disclosure A method of shimming a magnet having correction coils is provided.  The field strength in the bore of the magnet is measured at a predetermined number of points.  The field inhomogeneity is determined from the measured field strengths.  The field created by a fixed current in each shim coil operating alone, at each of the predetermined points is determined.  The shim correction coil currents are determined using a linear programming solver to minimize the field inhomogeneity and the correction coil currents.  The correction coil currents are determined based on the measured field in the bore of the magnet and the field created by each of the shim coils when carrying a fixed current, with the correction coil currents each constrained to a maximum value which is adjusted for the current in the correction coils when the field strength was measured.  The correction coils are adjusted to the determined values and the field strength of the magnet is again measured at the predetermined points. The inhomogeneity is again determined and compared to a desired value of inhomogeneity.  If the inhomogeneity is greater than desired, then shim correction coil currents are again determined, the determined shim coil currents set, and the field measured until the desired inhomogeneity is achieved.

Title: Method and device for the formation of an end closure on a hose-type packing wrapper
Inventor: KOLLROSS GUENTER
IPC: B65B9/18
Filed: 1991-04-26
Abstract: ABSTRACT     The method serves for the formation of an end closure in the form of a twisted plait on a hose-type packing wrapper, especially a sausage skin, shirred to form a caterpillar, with an unshirred wrapper section being formed on the end of the packing wrapper to be closed.  A first elongated winding element is introduced into the packing wrapper to behind the first shirring folds.  Subsequently, the unshirred wrapper section, by a second elongated winding element of a length shorter than that of the first winding element, is moved radially to the latter and is seized along an axial surface line.  Thereupon, the winding elements are actuated in rotating manner and, at the same time, are axially advanced, with the twisted plait being generated from the free end of the winding elements in a manner progressing to the rear. At the end, by retraction of the winding elements, a vent channel is exposed.

Filed: 1991-08-07
Abstract: ABSTRACT      The metallic hollow O-rings of the present invention are characterized by being composed of a metallic shell formed continuously in the circumferential direction into a ring-like form and a continuous hollow portion formed in the circumferential direction inside the metallic shell, said metallic shell being welded intermittently or continuously in the circumferential direction.   The process for producing metallic hollow O-rings is characterized by comprising a step of bending a material for metallic shell into a ring-like form so that a hollow portion is formed continuously in the circumferential direction inside the metallic shell and, at the same time, an opening portion is formed continuously in the circumferential direction in a space between the edge portions of said metallic shell, and a step of welding the edge portions together intermittently or continuously in the circumferential direction so that said opening portion is blocked partially or wholly.  According to the metallic hollow O-ring of the present invention, the metallic hollow O-ring having the welded structure, which is capable of easy and mass production and is excellent in sealing performance and mechanical strength, can be obtained and the O-ring having the above welded structure can be productively produced at low cost.

Abstract: According to a method and apparatus for coding a moving image signal, a change between a current frame and a previous frame is detected in units of blocks obtained by dividing a frame constituted by an input moving image signal into a plurality of pixels. A first valid block map is formed in units of frames by determining valid and invalid blocks on the basis of the detected changes. A first weighting operation of the formed first valid block map is performed. A second weighting operation of a fourth valid block map of the previous frame is performed. A weighted second valid block map is obtained by adding/synthesizing the first and fourth valid block maps respectively subjected to the first and second weighting operations. A third valid block map is obtained by performing predetermined segmentation of the second valid block map. A fourth valid block map is obtained by determining validity of an isolated invalid block in the third valid block map by referring to neighboring blocks.  A valid block region of the fourth valid block map is coded.
