Abstract: A gene (cDNA) encoding a bovine myostatin protein. The nucleic acid coding sequence is identified as SEQ ID NO:1 and the protein sequence is identified as SEQ ID NO:2. A mutant gene (SEQ ID NO:3) in which the coding sequence lacks an 11-base pair consecutive sequence (SEQ ID NO:11) of the sequence encoding bovine protein having myostatin activity has been sequenced. It has been shown that cattle of the Belgian Blue breed homozygous for the mutant gene lacking myostatin activity are double-muscled. A method for determining the presence of muscular hyperplasia in a mammal is described. The method includes obtaining a sample of material containing DNA from the mammal and ascertaining whether a sequence of the DNA encoding (a) a protein having biological activity of myostatin, is present, and whether a sequence of the DNA encoding (b) an allelic protein lacking the activity of (a), is present. The absence of (a) and the presence of (b) indicates the presence of muscular hyperplasia in the mammal.

Inventor: LINSENBARDT THOMAS L
IPC: H01F41/12
Filed: 1998-08-03
Abstract: A method and apparatus for manufacturing a variable insulated helically wound electrical coil is disclosed. Insulated rectangular wire is fed from a supply reel to a coating zone and within the coating zone liquid resin insulation is selectively applied to the wire so it has additional insulation only in those areas of the coil where the dielectric strength is needed. The insulated wire is fed through a curing station to allow curing of the additional insulation prior to winding the cured insulated wire into a coil. The cured insulated wire is wound into a coil of predetermined shape at a winding station whereby the portions of the wire having the additional insulatin are located in the areas of the coil where the greatest dielectric strength is needed. The timing of the resin application to the wire is coordinated with the winding of the coil so that the proper insulation thicknesses are achieved at the required locations in the coil. There is also disclosed a variably insulated helically wound high voltage electrical coil for a transformer wherein a variable thickness of cured synthetic resin insulation is applied to the turns in each layer of the coil so that the insulation increases in thickness from substantially zero at one end of the layer where layer-to-layer voltage stresses will be low and the required maximum thickness at the opposite end of the layer where voltage stresses will be high and this progression and insulation thickness is repeated on each adjacent layer of the coil.

Abstract: A process for enhancing the mounting surface of a hard surface comprises rotating a hard material having a planer mounting surface about an axis perpendicular to its surface and intercepting said surface with a laser beam directed along an axis which is at an angle to the surface's rotating axis.  The laser beam cuts a void through the rotating mounting surface and into the material, creating an undercut for enhanced mechanical bonding properties. By repositioning the relative positions of the laser beam and rotating surface, a plurality of different undercut voids can be formed. Preferably the laser beam can be pulsed and synchronized with the speed of rotation of the surface for cutting a pattern of undercut voids in the surface. Apparatus comprises a rotating plate to which the material is temporarily affixed, a drive for rotating the affixed mounting surface in its plane and a laser which emits a laser beam along an axis which intercepts the mounting surface and which is angled from the plate's axis of rotation. A controller and a two dimensional actuator control the relative coordinates of the intercept of the laser beam and mounting surface.  Preferably the speed of the drive is variable for ensuring the lineal speed of the mounting surface intercepted by the laser beam is maintained at or below a predetermined speed.

Filed: 2000-11-03
Abstract: A process which utilizes actual received signal level data gathered from closely spaced locations covering an entire cellular system to calculate interference levels at each location. The process determines those base stations which most probably communicate with a mobile unit at each particular location, compiles a list of neighbor base stations for each base station at each location throughout the system and calculates interference levels at each base station for a variety of channel assignment to each base station. The process allocates channels to various cells on an adaptive basis to minimize interference and maintain call quality. Minimizing interference requires a cost evaluation of all resulting interference from implementation of a particular channel allocation. Data which indicates the actual strengths of all signals to be transmitted by a plurality of cells each positioned at an individual physical position in a mobile communications system and to be received by a mobile unit at a plurality of points of an entire mobile communications system is collected and utilized to establish a relational data matrix. The system relating data indicating the actual strengths of all signals to the physical positions from which the signals are to be transmitted, identifying cells transmitting signals likely to serve each point of the plurality of points, and comparing planned frequencies to be used at any position serving a point with planned frequencies to be used at other positions to identify cells transmitting signals which might interfere with signals transmitted by cells serving a point and to identify least likely interference patters for channel reuse.
