Abstract: The machinery and methods disclosed herein are based on the use of a specialized extruder configured to continuously convey and plasticize/moltenize selected lignocellulosic biomass and/or waste plastic materials into a novel variable volume tubular reactor, wherein the plasticized/moltenized material undergoes reaction with circumferentially injected supercritical water—thereby yielding valuable simple sugar solutions and/or liquid hydrocarbon mixtures (e.g., “neodiesel”), both of which are key chemical commodity products. The reaction time may be adjusted by changing the reactor volume. The machinery includes four zones: (1) a feedstock conveyance and plasticization/moltenization zone; (2) a steam generation and manifold distribution zone; (3) a central supercritical water reaction zone; and (4) a pressure let-down and reaction product separation zone.

Abstract: A supercritical hydrocyclotron for transforming one or more selected polymeric materials into a plurality of reaction products via supercritical or near-supercritical water reaction that enable the rapid and economic conversion of solid biomass and/or waste plastic materials (i.e., organic materials) into smaller liquid and gaseous hydrocarbon molecules—smaller hydrocarbon molecules that, in turn, are useful as chemical feedstock materials including, for example, liquid transportation fuels and bio-adhesives. The innovative supercritical hydrocyclonic systems and related mobile units disclosed herein comprise, in combination, (1) a supercritical water (or near-supercritical water) treatment system for converting organic materials into smaller hydrocarbon molecules, and (2) a hydrocyclonic separation system for recovering the smaller hydrocarbon molecules from the combined water/hydrocarbon effluent.

Abstract: A composition capable of supplying ethylene gas to botanical systems is disclosed and includes a microporous solid having a plurality of cells and a quantity of ethylene gas contained within one or more of the plurality of cells. The cells can be either open or closed, and can be either permeable, degradable or both so as to release the ethylene over a period of time. The ethylene gas is released from the cells over a period of time. The release rate of the ethylene gas may be altered by changing the density of the microporous solid. The release rate may also be altered by manipulating the size or shape of the microporous solid.

Abstract: There is disclosed a filled cellulosic fiber composition, as well as a method for filling dried cellulosic fibers with an inorganic filler by contacting the dried fibers with a first salt solution, followed by contact with a second salt solution. The first and second salt solutions combine to form a precipitate within the cell wall of the cellulosic fibers. The filled cellulosic fiber composition may be made into a variety of paper products, including paper, having a high filler content. The precipitates of the present invention include carbonates, phosphates, silicates and borates of aluminum, barium, calcium, magnesium and zinc. The first salts include carbonates, phosphates, silicates and borates of sodium, ammonium, potassium and lithium, and the second salts include chlorides, nitrates, and sulfates of aluminum, barium, calcium, magnesium and zinc.

Abstract: Materials are disclosed which are used to produce traces on a circuit board by means of extrusion. The materials are polymer thick films (PTF) which are thixotropic. Conductive traces are composed of conductive particles, a resin and hardener, and two solvents, one having a relatively high volatility and one having a relatively low volatility. Thus when a newly deposited trace is subjected to a stream of hot air, the fast solvent will substantially evaporate leaving a firm paste behind over which another layer of PTF can be written without causing interference between the layers. The slow solvent then permits the various layers of traces to be polymerized together at the same time in a one step operation. The insulative material is similar to the conductive material in that it includes a resin and hardener and two solvents of differening volatility. In addition, in the preferred mode, it includes a gelling agent.

Abstract: An apparatus and method are disclosed for preparing electrically conductive traces on a circuit board using an additive technology. The traces are directly written in a serial process with each trace being able to be individually insulated. The apparatus includes an extrusion element for extruding a first material and a stage. The stage is for holding the extrusion element and the circuit board in relative proximity and for producing relative motion between the extrusion element and the circuit board in order to extrude the first material onto the surface of the circuit board along preselected paths to produce the electrically conductive traces. According to the method of invention, a first polymerizable material is extruded onto a circuit substrate support along preselected paths to form traces, and the first polymerizable material is polymerized, the first polymerizable material being conductive after polymerization.

Abstract: There is also disclosed a process for the production of filled paper using never-dried pulp fibers and filler comprising an insoluble precipitate that is precipitated in situ within the cell wall of the fibers. The process first immerses the never-dried pulp fibers in a first solution containing a soluble salt or salts, filters the pulp fibers from the first solution, and reimmerses the never-dried pulp fibers containing the first solution in the pores into a second solution, wherein the second solution comprises soluble salt or salts different from those of the first solution and able to form an insoluble precipitate with the salt or salts of the first solution. The filled, never-dried pulp fibers are filtered and washed and either used to form filled paper products or dried to filled pulp fibers for later use in papermaking.
