Title: Farming method using waste material
Inventor: ROSSET RENE R
IPC: A01C21/00
Filed: 1994-05-20
Granted: 2001-07-17
Abstract: A method of farming comprises collecting waste material such as manure from animal farming, or effluent from food processing plants or the like in a closed container, stirring and aerating the material within the container and adding yeast and phosphoric acid to increase aerobic bacterial activity while reducing anaerobic bacteria and rendering the material into a pumpable liquid. The material is then spread across the ground by a spreading action by pumping the material through a pipe carried on the reel of a vehicle having a boom of the order of 100 feet in width so that the material is sprayed onto the ground in an even spreading action at a rate of the order of 1000 to 5000 gallons per acre. Simultaneously an oxidizing agent such as hydrogen peroxide is sprayed onto the material, preferably immediately before the material. Prior to spreading, crop residue on the ground is chopped to small length and broken so that the oxidizing agent acts on the straw and allows the high level of aerobic bacteria in the waste material to decompose the straw with the waste material in a rapid action. Subsequently the soil is incorporated with the crop residue and material to a depth of two inches.

Abstract: A composition use in preparing an ordered carbon-containing material includes a-binder phase having at least one polymerisable resin and particles of solid material that are wetted by the binder phase.  The binder phase may optionally include a polymerisation promoter and/or a solvent.  The granulometry of the solid particles, the viscosity of the binder phase and the relative amounts of solid and binder phase are controlled such that through mixing of the solid particles and binder phase results in a thin layer of binder phase coating the particles.  Pyrolysis of the resulting mixture at 800 - 1,200 °C will produce an ordered, carbon-containing material.  The method for preparing articles from the composition includes mixing the binder phase and solid particles, shaping to a desired shape, curing and pyrolysing at 800 - 1,200 °C.  Ordered, carbon-containing materials are obtained at much lower temperature than previously and the carbon-containing materials so obtained are resistant to disruption by alkali metals such as sodium.  The composition and method are especially suitable for preparing cathodes for use in aluminium smelting cells.

Abstract: Apparatus (10) and method are described for processing waste into a clean fuel. The waste (22) comprises organic and inorganic portions. A float tank (18) is filled with a liquid, e.g., water, of a selected depth. The waste (22) is introduced into the liquid and separates into its organic portion, which floats near the surface of the liquid, and into its inorganic portion, which falls towards the bottom of the tank (18). The liquid depth is selected to be sufficiently large to permit the separation of an organic and inorganic portions. Then the organic and inorganic portions are removed. Sufficient liquid is extracted from the separated organic portion to provide a clean fuel. The fuel (102), illustratively, is formed as pellets. In a further aspect of this invention, further liquid is added to the separated organic portion to form a mixture thereof, which is pulped to provide a slurry thereof of a relatively high moisture content. Liquid (88) is extracted by mechanical means, e.g., a belt press (87) and/or a screw press (92), from the slurry to provide the clean fuel (102) of a relatively low, homogeneous liquid content.

Abstract: A vapor barrier laminate for use in insulation applications as a facing material.   A fiberglass yarn or scrim is positioned between layers of kraft paper. An aluminum foil is adhered directly to the outer kraft paper layer.  The paper to foil bond and the paper to paper bond are accomplished with a  flame retardant adhesive.   The resulting heavier and thicker laminate provides increased rigidity, a smoother outer surface for better abrasion resistance, and a greater tensile strength.  Use of the laminate in duct board facing improves the strength of the duct board while facilitating  tape  adherence  for  sealing  gaps  between  board sections.

Title: Liquid containment and dispensing device
Inventor: WALLACE JAMES KENNETH
IPC: B41J2/175
Filed: 1996-04-24
Granted: 2005-01-18
Abstract: An ink containment and dispensing device for an ink-jet printer is provided with a main reservoir in the form of a flexible pouch, which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet, which is normally closed to prevent the flow of outward ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer.      The pump has a linearly acting pumping member and a flexible diaphragm that overlies the pumping member, the diaphragm being impervious to the transmission of oxygen and moisture therethrough to prevent degradation of the ink within the chamber.

A low power electric heater (22) of known heat power value Ph (e.g. 10W) is mounted between the sensors (16 and 18) to add heat to the fluid passing through pipe (4). The sensors observe the temperature of the fluid thereat; Ti, t1 t2, and To being the temperature values observed by the sensors (14, 16, 18 and 20) respectively. The control (8) calculates the heat power Pd consumed by the region (36) form the fluid using the expression:PD Ph x Dd/Dh, where Dd - (Ti - To) and is substantially the temperature difference across the region (36), and Dh - (t2 - t1) and is the temperature difference across the heater (22).

IPC: B60L13/08
Filed: 1995-05-22
Granted: 1999-11-30
Abstract: An electrodynamic suspension system levitates a platform (1) or transportation vehicle (10) by an array of onboard superconduct-ing electromagnetic coils (20, 21) forming a primary member over-lying a secondary member (46) on the guideway (11) in a trans-verse flux orientation with respect to a plane of levitation of the moveable member (10) above the secondary member (46) on the guideway (11).  The superconducting coils (20, 21) are energized by alternating current to produce an alternating field of magnetic flux.  The frequency of the alternating current is selectable down to direct current.  The frequency is selected to cause the vehicle (10) to be levitated statically above the guideway (11).  Once levitated, the frequency is reduced as the speed of the vehicle (10) increases along the guideway usually not in excess of 60 miles per hour. Pas-sive electrically conductive plates (47) form the secondary member to respond to the alternating field of magnetic flux and both guide and levitate the vehicle (10) by inherently stable repulsive induction action.
