摘要： A process for producing electromagnetic silicon steel having a cube-on-edge orientation. The process includes the steps of: preparing a melt of silicon steel containing from 0.02 to 0.06% carbon, from 0.015 to 0.15% manganese, from 0.005 to 0.05% of material from the group consisting of sulfur and selenium, from 0.0006 to 0.0080% boron, up to 0.0100% nitrogen, up to 1.0% copper, less than 0.005% antimony, less than 0.009% aluminum and from 2.5 to 4.0% silicon; casting; hot rolling; cold rolling; decarburizing; applying a refractory oxide base coating; and final texture annealing. During final texture annealing the steel is heated from a temperature of 1700.degree. F. to a temperature of 1900.degree. F. at an average rate of less than 30.degree. F. per hour, and subsequently maintained at a temperature in excess of 2000.degree. F. for a period of time sufficient to effect a purification of the steel.

摘要： A baseball bat includes a body portion having a target area with a midline extending longitudinally through the target area center and along the bat's entire length to a handle portion having a pair of substantially planar regions spaced from each other and inclined toward the midline by a convergence angle of between about 50° and 70°. The planar regions are separated by curved surface regions joining the planar regions to each other and sloping regions at each longitudinal end of the planar regions. The bat provides enhanced tactile information concerning the dynamic characteristics of the bat during the swing up to and through contact with a pitched ball so that the batter can learn substantially improved location and trajectory control.

摘要： A training or safety aid for a baseball bat is disclosed. The device is configured to be placed on a bat, and indicators, which may be sound producing devices, produce a noise in accordance with selected qualities of the swing. In some embodiments, a flute-type opening is used, and may be configured with tubes to determine a pitch of a produced tone. An air scoop or funnel may be used with any of the devices that utilize airflow to produce a tone. Where more than one sound producing device is used, the devices are configured to only produce a sound within a narrow angular range of airflow, and are angularly spaced so as to produce sounds during different portions of a bat swing.
