  • Patent number: 6972156
    Abstract: A body (5) of set, initially pasty material, such as concrete, includes an electrically conducting path formed by a concentrated layer (6) of electrically conducting magnetizable elements, such as fibers (F) or granules (G), embedded in the initially pasty material and extending through at least a portion of the body (5). Electrically conducting terminal members (9) may be connected to the electrically conducting layer (6) at spaced-apart positions along the layer (6). A method of providing such a body (5) includes the steps of: (a) forming a body of the pasty material in which electrically conducting magnetizable elements (F) are dispersed, (b) applying a magnetic field to the body of pasty material to form from the magnetizable elements an electrically conducting layer embedded in the body of pasty material and extending at least through a portion the body (5), and (c) causing the body of pasty material containing the layer (6) to set.

  • Patent number: 6884328
    Abstract: Magnetic films are annealed by radio frequency (RF) radiation. During the RF annealing process, the layers may be subjected to a magnetic field in order to control their anisotropy axes. The RF annealed layers are useful for applications such as longitudinal and perpendicular magnetic recording layers of magnetic data storage media.

  • Patent number: 6740282
    Abstract: Magnetizable fibers dispersed in a viscous body, particularly reinforcing metal fibers dispersed in a wet cementitious material, is carried out by providing a fiber aligning member (15) having a nonmagnetic wall (17) including a first wall portion (17A) and a second wall portion (17B), moving the aligning member (15) relative to the viscous body with the first wall portion (17A) leading and the second portion (17B) trailing it and with the first and second wall portions (17A, 17B) contacting the viscous body, and directing a magnetic field into the viscous body through the first wall portion (17A) to subject the fibers (F) to a moving magnetic field.
