Magnetic sheets

, : Magnetic sheets. Official Gazette of the United States Patent & Trademark Office Patents 1248(5), July 31

A magnetic sheet comprising permanent magnetic particles arranged in a pattern to form alternating elongated zones of first and second opposite polarities, each zone being defined by spaced apart parallel zigzag boundary lines formed by a plurality of equal length, substantially linear segments which meet at point contacts to form sharp turns, with angles formed at the sharp turns and defined by connected segments being 90/, each zone of the first polarity being bounded by only two zones of the second polarity positioned on opposite sides thereof, and each zone of the second polarity being bounded by only two zones of the first polarity positioned on opposite sides thereof. The magnetic sheet of the invention has many applications, including a removable insole for insertion into footwear.

Hydroxylamine hydrochloride (NH2OH-HCl) and hydrogen peroxide (H2O2) have been used in the past for selective dissolution of manganese oxide minerals. The methods reported, however, give poor recoveries. We tried to improve the methods in this res...

Gait and balance dysfunction frequently occurs early in the multiple sclerosis (MS) disease course. Hence, we sought to determine the longitudinal relationships among quantitative measures of gait and balance in individuals with MS. Fifty-seven am...
