  • Magnetic therapeutic device for arthritic fingers
    Patent number: 6050931
    Abstract: Magnetic therapeutic device provides small lightweight rare-earth intense-field permanent magnets encased in a stretchable polymeric resin carrier held adjustably in position on the finger and joint areas of an arthritic hand by a resilient support strap attached to the ends of the magnet-carrier.
    Type: Grant

  • Magnetic medical treatment device
    Patent number: 5782743
    Abstract: A magnetic therapeutic device including a flexible elasticized loop-type fabric band or belt having a buckle loop at one end and a hook-type fastening element (VELCRO) at the other end thereof for securing the band or belt around the to-be-treated portion of a user's body, one or more magnetizable stainless steel C-shaped clips slidably mounted for adjustable positioning on the band or belt, each clip having at least one recess for magnetically holding at least one small high-intensity permanent magnet therein.

  • Treated toner magnetic carrier and method of making the same
    Patent number: 4268599
    Abstract: Method and means is disclosed for treating carrier particles in order to change the charge to mass ratio and the resistivity of a development powder encompassing such particles. The carrier particles are first coated with a polymer capable of providing reactive sites and then an additional treatment is carried out with a material that will react to the reactive sites. Another advantage of the treatment is that the carrier particles are protected from oxidation following such treatment.

  • Electroscopic carrier particles having a carboxylic acid surface treatment
    Patent number: 4247597
    Abstract: Disclosed is a treatment of electroscopic carrier particles with a solution of non-halogenated carboxylic acids. Preferably, the carboxylic acid solution is first passed through a dry agent to assure its anhydrous nature. The carrier particles are added to and agitated within the solution a sufficient period to assume complete wetting of the particles. After decanting and filtering, the carrier particles are dried. Carrier particles treated in this manner are less susceptible to oxidation and have particular utility for use in development powders for magnetic brush development units of electrophotography copier equipment.

  • Carrier particles having the surface thereof treated with perfluoro sulfonic acid and method of making the same
    Patent number: 4113641
    Abstract: It has been found that unexpectedly high charge to mass ratios may be achieved in a development powder if the carrier particle of the development powder is treated with a perfluoroalkyl sulfonic acid. Treating carrier particles with a monolayer of such an acid has produced charge to mass ratios of 20 to 26 .times. 10.sup.-6 coulombs/gm. The acid concentration in of the solution used in this treatment has been found to be critical.
