Abstract: The object of the invention is a magnetic arrangement for the treatment of surface near skin or tissue areas of the human body having several mechanically connected magnetic bodies (M.sub.1, M.sub.2) which build an active surface on, or in, the vicinity of which the magnetic field there present is utilized. Use has long been made in therapeutics of flexible magnets of plastic bonded hard ferrite having at least one North and one South pole on their active surface facing the body, whereby the pole configurations are arranged in different ways dependent upon the therapeutic objective. It is thus possible to generate magnetic inductions only in surface near skin or tissue areas. A magnetic arrangement of several magnetic bodies of high coercive field strength with different energy densities is proposed to attain locally restricted higher magnetic inductions.

Abstract: A permanent magnetic arrangement for therapeutic purposes, which comprises one or several rubber-type flexible magnetic foils or strips in which highly coercive permanent magnet particles are embedded in a tube-shape during the therapeutic treatment. The magnetic foils or strips are magnetized perpendicularly to their surface, whereby their magnetic field lines pass through the body section enclosed by the magnetic foil or foil pieces, in cross-wise and/or longitudinal direction. The magnetic foil or foil pieces are positioned in a textile fabric strip, which is provided on its open ends with a fastening mechanism, preferably a Velcro fastener in the form of a bandage. In order to increase the magnetic field line density, the magnetic foils or foil pieces or strips are positioned in layers one over the other, whereby in each case north poles of one foil are opposite south poles of the adjacent foil.

Abstract: A magnetic roll for electro-photographic copy machines is provided with a carrier to which strip-shaped permanent magnetic components are fastened in an axial direction. Recesses are provided in the carrier having a cross-section larger than the magnetic components so as to permit selective radial, tangential and pivotal movement for universal positioning of the components within the recess. The components are selectively oriented to provide a predetermined induction value as measured at a predetermined distance outwardly of the carrier or with respect to adjacent poles as determined by discretely located Hall probes. The permanent magnetic components are fixed in the prescribed orientation by an injection moldable plastic material such as a plastic foam.

Abstract: A flexible magnetic sheet for therapeutic use made of a rubbery-flexible synthetic material in which permanent-magnetic ferrite particles have been embedded, the surface facing the body site to be treated of said sheet having been magnetized with magnetic poles of alternating polarities, which poles are in the form of some geometrical shape such as concentrically arranged rings, sectors, quadrangles and the like. Such sheet may also be composed of a plurality of individual parts.

Abstract: A permanent magnet energized holding device for holding of, or onto, ferromagnetic objects and readily switchable between "on" and "off" positions, has outer and inner cup-shaped pole shoe members of good magnetically conductive material concentrically nested in spaced apart relation one inside the other with their rim edges or pole faces lying in a common plane. A ring-shaped stationary permanent magnet is fixed in the space between the peripheral side walls of the cup members, and the cup members and stationary magnet are correspondingly divided magnetically into two portions at the same points therearound by non-magnetic mediums. A rotatable permanent magnet sandwiched between the base end walls of the cup members is rotatable therebetween by an operating shaft or other actuating means to switch the holding device between its "on" and "off" positions. The two magnets are magnetized in the direction of their smallest dimension or thickness, with portions of each having opposite magnetic polarity.

Abstract: A permanent magnetic holding arrangement for temporarily holding at least two ferro-magnetic parts wherein the holding of the second part does not decrease the holding of the first part. A disc-shaped permanent magnet magnetized through its smallest thickness is positioned between two pole plates of magnetically permeable material, the thickness of the plates relative to the thickness of the magnet being such that a strong magnetic oversaturation of the plates result. Preferably, the ratio of the pole plate thickness to the permanent magnet thickness is 1:3 or larger.
