  • Deodorizing methods and articles using ion exchange manufacture
    Patent number: 4333183
    Abstract: Deodorizing is accomplished by contacting odorant, such as that exuded by humans, with solid, essentially non-fluid anion exchanger material in substantially extended form. Articles used in the method are typically those worn on the body, such as hose, or those used to envelop or wipe odoriferous substances and contain anion exchange cotton.
    Type: Grant
    Filed: November 9, 1978
    Date of Patent: June 8, 1982
    Inventor: Karel Popper
  • Methods and apparatus for continuously endowing liquid with mechanical energy by osmosis
    Patent number: 4177146
    Abstract: Liquid is continuously endowed with mechanical energy by continuously osmosing it across an osmotic membrane across which is maintained a substantial pressure difference of osmotic pressures. Continuity is insured by continuously flowing hypotonic liquid against and away from the hypotonic surface of the membrane, continuously flowing hypertonic liquid against and away from the hypertonic surface of the membrane, and continuously flowing permeate essentially limitlessly away from the hypertonic surface. The substantial osmotic pressure difference across the membrane is maintained, in part, by keeping the hypertonic liquid at or near saturation.
    Type: Grant
    Filed: May 5, 1975

    Inventor: Karel Popper
  • Treatment of crude sugar juices by ion exchange
    Patent number: 4140541
    Abstract: Raw sugar beet diffusion juice or raw cane press or diffusion juice is de-ashed by ion exchange using calcium hydroxide, calcium carbonate mangesium hydroxide or calcium sulfite for regenerant. Means are provided whereby slurries can be passed through an ion exchange resin bed without causing said bed to accumulate solids and to clog.
    Type: Grant
    Filed: March 25, 1977
    Date of Patent: February 20, 1979
    Inventor: Karel Popper
  • Regeneration of spent activated carbon with formaldehyde
    Patent number: 4073747
    Abstract: Spent activated carbon is regenerated by contacting it with formaldehyde in an amount sufficient to restore its activation. Following the treatment the regenerated carbon is rinsed to remove residual formaldehyde and is then ready for use.
    Type: Grant
    Filed: December 13, 1976
    Date of Patent: February 14, 1978
    Assignee: The United States of America as represented by the Secretary of Agriculture
    Inventors: Karel Popper, Wayne M. Camirand, Gerald S. Williams, Edward P. Mecchi
  • Preparation of puffed fruit
    Patent number: 4055675
    Abstract: Bite-size pieces of fruit are prepared by a process wherein the fruit is partially dehydrated, puffed, and then heated to obtain a crisp outer surface thereon. The fruit is puffed by immersing it in a pool of liquid carbon dioxide under pressure and then rapidly releasing the pressure.
