The Monsanto Company patent solves the following problem:

This invention relates to a dry, non-clumping herbicidal composition with a way to make the composition.

Our analysis of this patent is as follows:

Monsanto Company’s patent US 5633397 A deals with Preparation of ammonium glyphosate via a gas-solid reaction system.
Solid N-phosphonomethylglycine or glyphosate acid in "wet cake" form sent to a suitable mixer / reactor. A stoichiometric equivalent of anhydrous ammonia gas was fed into the mixer for the direct reaction of glyphosate acid as it was troubled in the mixer. A water jacket containing circulating water or other suitable heat transfer facilitating means then known in the art adapted to the mixer and used to remove heat from the reactor produced by exothermic reaction. The moisture content in the glyphosate wet cake, the design of the mixer including a rather close tolerance relationship between the inner walls of the reactor and the mixing impellers with where the ammonia gas inlet mixer / reactor and to continue a reaction temperature of about 60 C. or lower in all important process variables. The ammonium glyphosate as a highly sorptive, water-soluble powder suitable for use as a plant growth regulator or as a herbicide without further processing. Because of the highly sorptive character of reaction products, however, it is particularly well-suited for further work to absorb / adsorb an exceptionally high level of adjuvants such as wetting agents, anti-foaming agents and , in particular, surfactants.

The Minnesota Mining And Manufacturing Company patent solves the following problem:

Chlorofluorocarbons (CFCs called) is widely used as blowing agents in the production of polymeric foams. However, in recent years, CFCs were shown to contribute to the depletion of the ozone layer in the earth (because of their chlorine content), as well as global warming (because of their long atmospheric life). Therefore, there is general agreement that the place needed. (See "Montreal Protocol on Substances that Deplete the Ozone Layer," Copenhagen Amendments, United Nations Environment Program, 1992.)

Our analysis of this patent is as follows:

Minnesota Mining And Manufacturing Company’s patent US 5631306 A deals with Foamable composition containing unsaturated perfluorochemical blowing agent.
Foamable composition comprising (a) at least one normal liquid, unsaturated perfluorochemical blowing agent compound selected from the group consisting of perfluoroolefin compounds, for example, perfluoro (4-methylpent-2-ene), perfluoroaromatic compounds, for example, hexafluorobenzene and perfluorocycloolefin compounds, for example, perfluorocyclohexene, the perfluoroolefin compounds optionally containing one or more catenary heteroatoms; and (b) at least one foamable polymer or begin at least a foamable polymer. The compositions are useful in preparing polymeric, for example, polyurethane foams.

The Info Tec Llc patent solves the following problem:

The present invention relates to methods and systems for collective tracking demographics starter drug samples and especially the collective tracking demographics of the sample is given to a plurality of patients from a plurality of different share as the share announced starter drug sample given to the plurality of patients in different areas under the direction of the doctor for each patient to be quickly and easily analyzed.

Our analysis of this patent is as follows:

Info Tec Llc’s patent US 5628530 A deals with Method and system for collectively tracking demographics of starter drug samples.
A method and system for collective tracking demographics doctor (12,14) prescribed starter drug samples given to a plurality of patients (18,20) from a plurality of different places apod- distribution (38,40) used in a multipart product specific sample drug voucher, like a smart card (100) or a preprinted two voucher (102), has a part in marketing information ( 30,34) and a prescription separable portion (32,36) to be completed by prescribing doctor with starter drug sample number and dosage information with patient demographic information. The prescription portion (32,36) is separate from the marketing information (30,34) in pharmacy (38,40) or electronic with a card reader (112), if it is encoded in a Smart card (100) by a doctor (12,14), or physically by separation along a perforation (50), as recorded in a two-part voucher (102), and electronic retreivably stored in the pharmacy computer (130) from which the tracking information is transmitted electronically to a central remote computer (134), as the drug manufacturer, for subsequent energy analysis of markets (136).

System and method for enhanced printing

You’ve invested time, talent, and energy into making a dent in the universe with your invention and ideas. Now it’s time for Utility, Provisional or Design Patent Creation with PowerPatent software and services.

The Texas Instruments Incorporated patent solves the following problem:

This invention relates to printing, more specifically in printing with enhanced picture and gray scale.

Our analysis of this patent is as follows:

Texas Instruments Incorporated’s patent US 5627580 A deals with System and method for enhanced printing.
Higher quality printing is difficult to implement the spatial light modulator printers. The two major problems in keeping the gray scale in the line of funds, and to eliminate staircasing things in the pictures printed (81). This can be improved by using a different way of resetting the cells in the spatial light modulator when the data load cells, timing delay (86), a horizontal offset (84), and differently sized pixels ( 80, 82).
