    Type: Grant
    Filed: November 17, 1980
    Date of Patent: October 11, 1983
    Inventor: Maurice Seiderman
  • Casting of polyelectrolytes in hydrogel molds
    Patent number: 4273734
    Abstract: Conformable hydrogel molds or forms are adapted for the casting of polyelectrolytic materials whereby an irreversibly gelled, three dimensional article faithfully reproduces the interior topography of the mold.
    Type: Grant
    Filed: September 24, 1979
    Date of Patent: June 16, 1981
    Inventor: Maurice Seiderman
  • Culinary mixer and disintegrator
    Patent number: 4256407
    Abstract: A culinary mixer and disintegrator for receiving material to be blended, comminuted, or liquefied, having a container body defining a lobular cavity for accommodating the material to be blended, comminuted, or liquefied, the cross section of the cavity being of generally Figure-8 configuration with plural distinct lobes, each provided with a comminutor/blender blade rotatably disposed therein.
    Type: Grant
    Filed: December 16, 1975
    Date of Patent: March 17, 1981
    Inventor: Maurice Seiderman
  • Fenestrated hydrogels for contact lens use and method for making same
    Patent number: 4068933
    Abstract: A process for the reproducible manufacture of fenestrated hydrogels is described whereby unpolymerized hydrogel monomers are cast, polymerized in the mold and fenestrations produced in situ.
    Type: Grant
    Filed: March 18, 1975
    Date of Patent: January 17, 1978
    Inventor: Maurice Seiderman
  • Electrochemically linking collagen fibrils to animal tissue
    Patent number: 4034750
    Abstract: Skin-like collagen membranes are adapted for protecting a wound, lesion or the like on animal bodies. These collagen membranes are semipermeable and are electrochemically-linked to the damaged collagen fibrils of the animal body. This electrochemical biological junction is established iontophoretically from an electric potential derived from the body's own inherent electrical characteristics or a galvanic couple.
    Type: Grant
    Filed: April 22, 1975
    Date of Patent: July 12, 1977
    Inventor: Maurice Seiderman
  • Contact lens from hydrophilic gel polymers of polyvinylpyrrolidone and hydroxyalkyl methacrylate
    Patent number: 3966847
    Abstract: A plastic or resin product is obtained by mixing polyvinylpyrrolidone, modifiers and additives such as organic methacrylates, and crosslinking agents, and optionally catalysts, and causing polymerization to take place. The inventive product is insoluble in water but is hydratable with water, depending upon the proportions of the above mentioned components, and may take up in its structure as little as 5% by weight of water to as high as 90% by weight of water. The inventive hydrated product is optionally transparent, translucent, or opaque, and produced in any shape or size, depending only on the mold in which it is cast. The transparent product is especially suitable for contact lenses. The translucent and opaque products may be fabricated into membranes with pore sizes that can be made selectively, or cast into useful shapes and for other uses.
