Title: Ammoniation of ground leonardite ore for dust suppression
Inventor: KEEN DAVID
IPC: G03G9/08
Filed: 1993-02-24
Abstract: ABSTRACT           A method of manufacturing relatively dust-free, water-soluble ammonium humate particles for agricultural, plant growth and drilling fluid viscosity lowering uses and to a method of improving the yield of agricultural and horticultural crops by ammoniating a ground leonardite ore.  Ground and at least partially dried leonardite ore is contacted, during or after grinding, with an aqueous solution of ammonia to substantially suppress dust formation resulting from the grinding operation and to render the leonardite ore particles substantially more absorbent to aqueous nutrients and more easily dispersed into soil for agricultural purposes.  The ammoniated leonardite ore particles also are more useful for lowering the viscosity of drilling muds and other known uses for leonardite ore.  In one embodiment, fertilizers, e.g., N-P-R additives, can be blended with the ammoniated leonardite ore to further improve the nutrient-supplying capacity of the ground and ammonia-treated leonardite ore.  The treatment of ground leonardite ore with ammonia to essentially eliminate dust is particularly advantageous when the ground leonardite ore is mixed with fertilizers, such as N-P-K (nitrogen, phosphorous and potassium fertilizer blends).

Title: Efficient microcapsule preparation and method of use
Inventor: WALLACE SIDNEY
IPC: B01J13/20
Filed: 1991-10-02
Abstract: The present invention relates to a highly efficient method of preparing microcapsules suitable for encapsulation or surface attachment of therapeutic and diagnostic agents. In one aspect of the invention, surface charge of the polymeric material is altered by conjugation of an amino acid ester to the polymer, providing improved targeting of encapsulated agents to specific tissue cells.  Examples include encapsulation of hydrophilic radiodiagnostic agents in 1 µm capsules to provide improved opacification and encapsulation of cytotoxic agents in 100 µm capsules for chemo embolization procedures. The microcapsules are suitable for attachment of a wide range of targeting agents, including antibodies, steroids and drugs, which may be attached to the microcapsule polymer before or after formation of suitably sized microcapsules.

IPC: B42F13/06
Filed: 1991-10-01
Abstract: A paper sheets binder has a pair of elongated strips (40, 50), one strip (40) mounting a spaced integral hinged pawls and the second strip (50) mounting matching spaced integral bifurcated ratcheted posts (51, 52. 53). The strips forming legs (54. 55) are mounted on front and back margin edges of a paper sheets stack (7). The post legs are oriented so that the end posts (51, 52) have a major axis parallel to the longitudinal axis of the strip. Breakage at the root of the end post legs is essentially prevented upon bowing of the document and strips and resultant shear forces. The intermediate posts (53) are oriented so that the legs major axis is transverse to the strip longitudinal axis to minimize bound document gutter (60) width and maximize flattening of an opened document against an image copier platen.

Abstract: SPECTRUM EXTENSION PROTOCOL FOR SECOND                GENERATION CORDLESS TELEPHONE     Abstract of the Disclosure A base station (10) includes a scanning receiver (18) for scanning a plurality of channels to measure an RSS level for each channel scanned. The base station includes a computer controller (16) that stores the measured RSS levels to create a table of RSS values. If a link request is received by the base station from a radio telephone handset on a first channel, prior to granting an RF link, the base station determines whether the first channel has an RSS level above a predetermined threshold. If the RSS level of the first channel is above the threshold, the base station re-assigns a second channel, that has an RSS level below the predetermined threshold, to the radio telephone.

Abstract: 2111240 9222734 PCTABScor01 A method is described for reducing the total emissions during cold starts from an engine burning a hydrocarbon fuel and having an afterburner arranged upstream of a catalytic converter. The method comprises the steps of: (i) adding an excess of fuel to the engine combustible charge and adding air to the engine exhaust gases immediately after the engine has first fired to assure the presence in the exhaust/air mixture of sufficient concentrations of hydrogen and oxygen to permit the resulting exhaust/air mixture to be ignitiable and to burn with a steady flame in the afterburner while the latter is at a temperature close to the ambient temperature, and (ii) igniting the exhaust/air mixture in the afterburner immediately after the engine has first fired. In the preferred embodiment of the invention, the excess fuel and/or the additional air are regulated after ignition has occurred in the afterburner to maintain a steady flame in the afterburner until at least part of the matrix of the catalytic converter has reached its light off temperature.

Filed: 1994-02-23
Abstract: A method for Aligning the process tools of a typical box blank die-cutting machine is provided herein. The method contemplates the use of alignment openings on the surfaces of male and female tools corresponding to a cut through-hole on a test sheet. As the test sheet is urged through the procedure, a series of alignment cylinders is used to insure that each of the male and female tools and test sheet are aligned by having the alignment cylinders fall cleanly through the various alignment openings and the through-hole. Once the tools at each position of the procedure are aligned, alignment screws and alignment members on the machine frame serve to fix the position of the tools relative to the position of the sheets to be die-cut, stripped and blanked. Accordingly, the method contemplates alignment and set-up of the machine based upon the urged position of the sheets to be etched and cut.

Title: Automatic line trimmer head
Inventor: EVERTS ROBERT G
IPC: A01D34/416
Filed: 1991-10-29
Abstract: A line trimmer head (10) for a vegetation cutter having an automatic line feed mechanism which replenishes the line (19) as a result of changes in centrifugal force. The line trimmer head (10) comprises a reel housing (14) which rotates with a shaft (12). A  spool (18) containing a supply of line (19) is located within the housing (14). An indexer cam (16) is journaled on the shaft (12) and is axially and rotatably shiftable with respect to the shaft (12). The indexer cam (16) is periodically axially shifted and rotated by a reduction in the centrifugal force applied by the line (19) to the spool (18). A spring (20) is provided to bias the indexer cam (16) axially relative to the housing (14) away from an interlocked position. In the interlocked position, the indexer cam (16) and housing (14) are interlocked together so that the spool (18), indexer cam (16), housing (14) and shaft (12) rotate together. The indexer cam (16) is shifted axially to cause the indexer cam (16) to be disengaged from the housing (14) allowing the spool (18) and indexer cam (16) to rotate relative to the housing (14). As the spool rotates a predetermined incremental amount relative to the housing, an increment of line (19) is fed from the spool (18). Centrifugal force applied by the line (19) may be reduced by either a reduction in the length of the line (19) or by a reduction in the speed of rotation of the shaft (12).
