Title: Continuous method for preparing polyacrylate resins
Inventor: ALEXANDER WILLIAM
IPC: A61L15/60
Filed: 1986-06-23
Granted: 1991-01-22
Abstract: Abstract of the Disclosure A method and apparatus for continuously manufacturing water absorbing resin.  A mixed monomer solution is stored in a storage vessel and a polymerization initiator stored in an initiator storage vessel.  The monomer solution is fed by gravity or otherwise through conduit to a lower position (below the liquid surface) of a reaction chamber of a reaction vessel at a rate of, for example, 4 gallons per minute.  Simultaneous-ly, the polymerization initiator is fed at a rate of, for example, 0.2 gallons per minute by gravity or otherwise through a conduit to an opposite side of the reaction chamber, again at a lower portion (below a continuously maintained liquid level) to begin polymerization.  The reaction product forms from an upper surface of the reactant mixture (mixed monomer solution plus initiator) and travels upwardly through a truncated frustoconical cone shaped upper portion of the reaction chamber as a solid resin.  The reaction product is sufficiently rigid to proceed upwardly from an upper annular edge of the upper reaction chamber portion until the resin meets an upper con-veyor belt.  The upper conveyor belt, driven in a counter-clockwise direction, pushes the mass of reaction product onto a lower conveyor belt on which the resin cures and dries without the addition of external heat.

Inventor: NORRIS ROBERT D
IPC: B09B5/00
Filed: 1987-08-06
Granted: 1991-02-19
Abstract: METHOD FOR DISTRIBUTING AN AQUEOUS SOLUTION CONTAINING A PEROXYGEN IN CLAY ABSTRACT OF THE DISCLOSURE The present invention is a method for distributing a colloid-free, aqueous solution containing a peroxygen compound in a particulate matter containing clay without causing the clay to swell. It has been found that hydrogen peroxide alone causes swelling of clays. It is well known that monovalent ions cause clays to disperse and swell. It is unexpected to find that perborate and persulfate anions do not cause clays to swell, even in the presence of sodium ions. The process is useful for enhancing the biodegradation of contaminants in clayey soils or for winning mineral values from clayey ore deposits.

Abstract: ABSTRACT In an ADPCM encoding and decoding  system comprising an encoder having an adaptive predictor and an adaptive quantizer and a decoder having an adaptive predictor and an inverse adaptive quantizer, the adaptive predictors each comprise:  an adaptive-zero predictor of an arbitrary order and an adaptive-pole predictor of an arbitrary order, for input signals with time-varying frequency components; a fixed-pole predictor of an arbitrary order. for input signals the frequency composition of which remains substantially invariant over time; and an offset predictor for rejecting an offset component of the input signals, these elements being connected in series.  The adaptive-zero and adaptive-pole predictors generate estimates for voice signals with time-varying frequency components.  The fixed-pole predictor generates estimates for voiceband data signals the frequency components of which remain substantially invariant over time.  The adaptive predictors effectively operate for voice and voiceband data signals, providing a higher prediction gain. The quantizer provides a stably higher signal-to-quantization noise ratio for modem signals.
