  • Atrial natriuretic peptide (ANP) as an additive to peritoneal dialysis solutions
    Patent number: 5965533
    Abstract: The present invention provides a peritoneal dialysis solution that contains atrial natriuretic peptide (ANP), a derivative of ANP, an analogue of ANP, a substance that binds ANP to clearance receptors or a substance that promotes ANP synthesis, which results in an increased net ultrafiltration and increased sodium clearance experienced in peritoneal dialysis patients.
    Type: Grant

  • System and method for providing sterile fluids for admixed solutions in automated peritoneal dialysis
    Patent number: 5925011
    Abstract: A system and a method are provided for admixing solutions. The system includes containers separately accessible by one or more pumps for mixture of the solutions in a container immediately before administration to a peritoneal cavity of a patient. Alternatively, the system and method allow for direct administration of the mixed solution to the peritoneal cavity of a patient without intermediate mixing thereof. The solutions may be mixed in predetermined ratios as input to the system prior to delivery.

  • Process for manufacturing rare earth-iron-boron permanent magnet alloy powders
    Patent number: 5183494
    Abstract: A process for producing rare earth-iron-boron permanent magnet alloy powders comprising; heating pellets comprising a mixture of rare earth oxides, iron power, ferroboron powder and calcium grandules for reaction/diffusion to obtain a rare earth-iron-boron alloy of uniform composition, crushing the resulting alloy to form a powder and contacting the powder with an aqueous solution of acetic acid containing a non-ionic surfactant and an alkai metal acetate.

  • Process for preparing rare earth-iron-boron alloy powders
    Patent number: 5064465
    Abstract: A process for preparing by a reduction/diffusion method rare earth-iron-boron alloy powders useful in permanent magnets. The process generates rare earth-iron-boron alloy powders having large and uniform particle sizes with minimal contamination. The process entails the use of a seed alloy among the starting materials, the seed alloy having substantially the same composition as the rare earth-iron-boron alloy to be prepared.
