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&#x2014;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. The machinery and methods minimize water usage&#x2014;thereby enabling the economic utilization of abundant biomass and waste plastics as viable renewable feedstocks for subsequent conversion into alternative liquid transportation fuels and valuable green-chemical products.

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. In a preferred embodiment, the first salt is sodium carbonate, the second salt is calcium nitrate or calcium chloride, and the precipitate is calcium carbonate.

Compositions and methods for filling dried cellulosic fibers with an

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.

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.

Liquid compositions provide a source of a herbicide or other biologically active substance in combination with a particular nitrogenous chemical, preferably melamine. After application, the herbicide is characterized by enhanced efficacy as compared to the efficacy observed when applied alone.

Liquid herbicidally active compositions

Relates to a fertilizer product in granular form, to processes for making and using it. The granules have strength, sizes and weights suitable for mechanical dispensing and application to and into the soil. These granules combine particles of a nitrogen source of poor solubility in pH 7 water at 20.degree. C., that converts slowly to a useful form, together with a binder that holds these fine particles together.

Pesticidal compositions based on nontoxic, naturally unstable insecticides (pyrethrum, synthetic pyrethroids and mixtures thereof) include a liquid alkyl aryl silicone polymer which stabilizes the insecticide to provide an extended effective killing life. The compositions additionally include a synergist to provide an immediate killing action and an antioxidant to protect the insecticide against destruction by oxygen. Ultraviolet protectants and insect repellents may also be included. Applications include control of insect pests to animals and plants and general purpose insect control. Exemplary formulations are given for compositions to be applied as sprays, dips, powdered or dusts, foggers and shampoos.
