  • Membrane processes for separation of organic acids from kraft black liquors
    Patent number: 4584057
    Abstract: An aliphatic organic acid fraction is separated from the kraft black liquor by subjecting the liquor to ultrafiltration, treating the resulting permeate by electrodialysis, acidifying the resultant deionate to about pH 4-5, separating the lignin solids which precipitate following this acidification, raising the pH of the separated solution to about 7-8 and finally subjecting the neutralized solution to electrodialytic water-splitting.

  • Process for reinforced yarn with glass fiber core
    Patent number: 4541231
    Abstract: A unique process for producing torque-free or balanced yarns of staple fibers with glass filament cores is disclosed. Staple fiber roving is fed through a drafting system. Glass filament is fed into the center of the staple fiber just prior to entering the front rolls of the drafting system. Sufficient twist is applied to the fiber around the glass filament using the ring spinning process and two or more of these yarns are ply twisted in the opposite direction of the spinning direction to firmly lock the staple fiber to the glass filament. The twist multiplier range for spinning is between 3.0 to 3.5 and for plying is betwen 3.5 and 4.5. Cotton fiber is the principle fiber used with a glass filament core. The resulting yarn can be tied by knotting onto existing loom beam ends when breaks occur during weaving without shearing of the yarns.

  • Continuous tree harvester
    Patent number: 4540033
    Abstract: A tree harvesting device which continuously severs and collects trees in a motion which is not governed by the motion of the carrier vehicle is described. The carrier vehicle moves from tree to tree in a continuous motion while the severing mechanism severs each tree in turn and then loads the cut trees into containment means within the harvester. Once the harvester is fully loaded, the containment mechanism releases and the harvester deposits the load in a bunched pile ready for subsequent handling and processing.

  • Agents to produce durable press low formaldehyde release cellulosic textiles: etherified N,N-bis(hydroxymethyl)-carbamates
    Patent number: 4539008
    Abstract: Hydroxymethylated organic carbamates are reacted with water soluble alcohols to produce etherified hydroxymethylated carbamates which are used with an acid catalyst to treat cellulosic textiles for sufficient time and temperature to produce a durable press low formaldehyde release cellulosic textile. Carbamates from the group consisting of alkyl or alkoxyalkyl carbamates of less than six carbons can be used. Water soluble aliphatic monohydric and polyhydric alcohols of one to six carbons are also satisfactory. The hydroxymethylated carbamate is reacted with the alcohol at about 10.degree. C.-100.degree. C. for about 0.5 to 16 hours at a pH from about 1 to 6. Concentrations of acid catalyst range from 0.5 to 3.0% of the solution. Curing temperatures range from about 120.degree. C. to 160.degree. C. for about 0.5 to 10 minutes.

  • Detection of agricultural contraband in baggage
    Patent number: 4539648
    Abstract: A radiant energy imaging system for selectively enhancing the image of objects having circular cross section to distinguish them from the image of objects having rectangular cross section, such objects being contained in a material having a different density-absorption coefficient product than the objects. In the invention, the gradient image of the spatially resolved transmitted intensity of the radiation is calculated and eroded to preferentially remove the edges of images of objects having rectangular cross section. The invention finds particular use in detecting agricultural contraband contained in baggage or parcels.
