  • Patent number: 6615454
    Abstract: In the cleaning of cotton, flax and kenaf and related materials in the ginning process there is typically a loss of cotton in the saw type lint cleaner. Amounts lost here are typically in the range of about 20 pounds per 500 pound bale. The present invention is directed to the inclusion of an additional saw cylinder in the saw type lint cleaner for the purpose of separating the cotton out of the rejected fiber from the passage through the first saw tooth lint cleaner. The additional saw is doffed by the same brush cleaner that doffs the primary saw cylinder.

  • Patent number: 6537947
    Abstract: Activated carbons derived from low-density lignocellulosic agricultural waste, and for use in absorption of metals, are prepared utilizing carbon dioxide or steam activation at 800° C. to 950° C. for 3 to 12 hours and subsequent oxidation with air at 260° C. to 400° C. for 3 to 6 hours. Granular carbons are formed by the inclusion of a preliminary two-step process involving the admixture of a binder selected from molasses, coal tar or wood tar to form pellets, briquettes or extrudates and converting them into a char under an inert atmosphere at 700° C. to 750° C. for 1 to 2 hours.

  • Patent number: 6536690
    Abstract: A method for separating non-fibrous particulates from fibers in the substantial absence of water is disclosed. A pulverized mixture of non-fibrous particulates and fibers is introduced into a separation zone containing a plurality of revolving spiked cylinders. Revolving spikes of the respective revolving spiked cylinders contact and separate fibers from the pulverized mixture to produce non-fibrous particulates. The separated fibers have residual non-fibrous particulates which may be removed by the revolving spikes of one revolving spiked cylinders throwing or impelling the separated fibers against and into the revolving spikes of a contiguous revolving spiked cylinder. When the separated fibers impact the spikes of the contiguous revolving spiked cylinder, residual non-fibrous particulates loosen and separate from the removed fibers. The produced non-fibrous particulates have residual polyester fibers which may be removed and reclaimed.

  • Patent number: 6363844
    Abstract: A device for the placement of bale ties, to effect repair of cotton bales which have been damaged as a result of bale tie failures. The device, which allows placement of multiple ties without individual bale movement, includes a base frame structure, an upper platen transversely locatable upon said base frame structure for paired contraposition with a lower platen, and a lower platen base attached to said base frame structure containing a plurality of lower platens mounted thereon that are able to reversibly recede therein when not needed for application of a localized compressive force. The platens are mounted on the structure for relative intraplanar movement toward and away from one another with the compression surfaces disposed in substantial parallelism. The platens are positioned for compressing a damaged cotton bale therebetween as the upper platen moves, by means of a reciprocating drive mechanism, toward its aligned opposite.

  • Patent number: 6245294
    Abstract: The killing of microorganisms on the surface of porous and non-porous materials including agricultural commodities is accomplished by use of methods and apparatus which expose the material to controlled applications of a biocidal treatment gas into a sub-atmospheric environment. The material is first exposed to a vacuum then, without an intervening flush step, full treated with an air-free treatment gas prior to being re-exposed to a vacuum. The method and apparatus successfully kill microorganisms both on the surface and within the pores or structural recesses of the material without causing significant deleterious changes to the material.

  • Patent number: 6201144
    Abstract: Fatty ether compounds and a process for their production is disclosed. The compounds possess low viscosity and low temperature melting point properties and may be used as viscosity modifiers in the creation of cosmetics and complete vegetable oil based biodegradable fluids such as hydraulic fluids and dielectric fluids. Formation of these fatty ether compounds is by reaction of the appropriate hydroxy fatty acid or lactone with a nucleophilic alcohol in the presence of an acid catalyst to produce fatty ether esters. Following their formation, the fatty ether esters may be recovered for subsequent use, or in the alternative, they may either be hydrolyzed to produce fatty ether acids or transesterified with a different nucleophilic alcohol in the presence of an acid catalyst to produce alternate ester variants.

  • Patent number: 6143304
    Abstract: Enhanced recovery of podophyllotoxin from biological sources is achieved through disruption or permeabilization of the physical integrity of cells and tissues in the presence of sufficient moisture so as to allow endogenous enzymes to convert podophyllotoxin glucosides to podophyllotoxin. Extraction of the podophyllotoxin from the plant material is then achieved by use of an organic solvent. Podophyllotoxin is used as an intermediate in the production of the antitumor agent etoposide and its analogues.

  • Patent number: 6033573
    Abstract: Activated carbons derived from nutshells, and for use in adsorption of metallic cations, are prepared utilizing phosphoric acid activation with concurrent oxidation under air. The acid activation is carried out utilizing a one or two-step heating regime subsequent to the infusion of the phosphoric acid into the nutshell material during which concurrent oxidation is achieved by exposure to atmospheric oxygen. Further oxidation is optionally achieved by equilibration of the nutshell carbons to room temperature under air. Prior to utilization, a washing step is employed to remove unwanted acid from the carbon product.

  • Patent number: 5921174
    Abstract: A device for placement of bale ties to effect repair of cotton bales which have been damaged as a result of bale tie failure, includes a base frame structure and a pair of compression platens provided with elongated, generally longitudinally extending bale contacting and compressing surfaces. The platens are mounted on the structure for relative intraplanar movement toward and away from one another, with the compression surfaces disposed in substantial parallelism. The platens are positioned for compressing a damaged cotton bale therebetween as the platens move toward one another. The compression surfaces of the platens have a width which is sufficiently small to compress a damaged cotton bale only in close proximity to a position where a single replacement bale tie is to be placed. A drive mechanism is coupled to the platens for moving the latter relatively toward one another to effect bale compression.

  • Patent number: 5897952
    Abstract: Temperature adaptable fibers are provided in which a polyol/glyoxal based crosslinking system is used to create a water-insoluble polyacetal coating. The formaldehyde release properties characteristic of methylolamide finishing agents is avoided. The non-catalytic reaction utilizes stoichimetric amounts of sulfonic acids to derivatize the polyols which in turn react with the glyoxal to form a water-insoluble polymer. The material also possesses improved properties relating to soil release, durable press, resistance to static charge, abrasion resistance, pilling resistance and water absorbency.
