  • Process to impart smooth-dry and flame retardant properties to cellulosic fabric
    Patent number: 4536422
    Abstract: Fabric is padded with a solution of nitrogen rich N-methylol crosslinking agent, acid catalyst, antimony oxide and a halogen containing alcohol; dried at about 140.degree.-190.degree. F. and then cured at about 250.degree.-400.degree. F. for sufficient time to impart smooth-dry and flame retardant properties to said fabric. Aqueous polyethylene or silicone emulsion softeners can be added to the padding solution if desired. Glycol, polyol and dibromoneophentyl glycol make exemplary halogen containing alcohols. The process can also be varied to first pad with antimony oxide, dry, and then repad with a solution of: nitrogen rich N-methylol crosslinking agent, acid catalyst, and a halogen containing alcohol, dry again and cure, at the temperatures specified supra.

  • Electrodynamic method for separating components
    Patent number: 4534856
    Abstract: A method of separating the components contained in agricultural by-products is disclosed. A set of parallel electrodes encased in a plastic panel and energized by an A.C. power supply is used to create an undulating traveling wave electric field. A voltage charge is first applied to the individual components. The voltage is then increased to effect levitation and movement of the components in opposite directions which results in separation. The voltage is cycled between charging and separating voltages to move the components over a distance for collection and recovery.
