  • Patent number: 8227719
    Abstract: Fusarium infected grain is separated by comparing reflected and transmitted light at two wavelengths, one at which the light is substantially reflected and scattered the same by healthy and infected kernels, the other at which the light is reflected and scattered to a significantly greater degree by infected than healthy kernels. An apparatus having a rotating apertured cylinder, with a low internal vacuum, allows comparison of individual kernels. When comparison indicates that a kernel is infected, a lever dislodges it from the cylinder allowing it to fall into a receptacle for infected kernels. Kernels remaining on the cylinder are scraped off to fall into a receptacle for healthy kernels. Although results vary, to some extent depending on the degree of infection, approximately 90% of healthy kernels and 5% of infected kernels are deemed “healthy”, while approximately 10% of healthy kernels and 95% of infected kernels are deemed “infected,” reducing the level of infected kernels.

  • Patent number: 6819009
    Abstract: A method for prevent unauthorized access to a vehicle is disclosed. The method includes apparatus which is positioned within a known motor housing and actuatable only within the motor housing. In one embodiment, an ignition generator coil interrupt circuit is provided and mounted directly within the housing of the motor. A switch is connected to the circuit which allows power interruption to the ignition generator coil. When the switch is activated power interruption of said ignition generator coil is achieved to disable the engine from starting. Conveniently, the interrupt circuit is positioned entirely within the housing and therefore inaccessible for tampering. In another embodiment a switch circuit is positioned between an ECM motherboard and sensors typically associate with an automobile engine. This circuit is useful for arrangements which do not include a magneto/stator arrangement.

  • Patent number: 6805821
    Abstract: A method of wet granulation of fertilizer and other materials into granules. The method involves formation of the granule directly on the pan from the feedstock without intermediate steps or the use of seed materials. The result is a product having a completely uniform cross section. The feedstock is initially in the size distribution of −150 mesh with 90% or greater in the size range of 200 mesh. Moisture is maintained to facilitate a steady process without cycling. The method has the advantage of allowing granulation of materials either known to be hazardous or inherently difficult to granulate in a safe and expedient manner. The process permits the formation of multiple feedstock granules. The initial feedstock may be augmented with a different feedstock in a second pan having a different composition and size from the initial feedstock.

  • Patent number: 6417290
    Abstract: Polymerization of &agr;-bromomethyl-&agr;-methyl-&bgr;-propiolactone (BMMPL) or &agr;-chloromethyl-&agr;-methyl-&bgr;-propiolactone (CMMPL) yielded thermoplastic homopolymers that upon azidation led to a novel energetic thermoplastic polyester: poly(&agr;-azidomethyl-&agr;-methyl-&bgr;-propiolactone) (PAMMPL). An energetic copolyether-ester thermoplastic elastomer was prepared by using glycidyl azide polymer, a dihydroxyl terminated energetic polymer, as a macroinitiator for the polymerization of BMMPL or CMMPL. The azidation of the resulting copolyether-ester yielded an energetic thermoplastic elastomer that melted at between 80° C. and 85° C. Polymerization of &agr;-dibromomethyl-&bgr;-propiolactone (DBMPL) resulted in a polymer which upon azidation yielded a new energetic polymer that can be used as a binder or into an energetic thermoplastic elastomer synthesis.

  • Patent number: 6375803
    Abstract: A method and apparatus for removing a contaminant from a fluid feed stream containing the contaminant. The method includes the steps of providing a feed stream (10) and heating it in a first step (18) to at least partially remove some of the contaminants and recover energy from a concentrate and distillate generated. Further heating the feed stream in a second heating step (20) in a heated separator generates a saturated vapor fraction (30) and a concentrated liquid contaminant fraction. The vapor fraction (30) may be compressed (32) to generate a temperature differential in the reboiler exchanger (34) with the vapor fraction being passed into contact with a reboiler exchanger (34) to provide a stream of condensed vapor from the reboiler. The stream may be circulated through the reboiler exchanger (34) and the heated separator to maintain from about 1% to about 50% by mass vapor in the stream.

The process involves the use of sodium sulfate which is electrolyzed in an electrolytic cell and which results in the production of sodium hydroxide and ammonium sulfate. The process carried out in a two or three-compartment electrolytic cell and the ammonium sulfate is converted by ammoniation and treatment of the ammoniated mixture with potassium chloride to produce potassium sulfate. Potassium sulfate may then also undergo electrochemical treatment to produce potassium hydroxide and ammonium sulfate.

  • Patent number: 6372123
    Abstract: A method for contaminant and water removal from crude oil. The method involves recirculating at least a portion of the dewatered crude into a dehydrator. The dehydrator contains a heated dehydrated crude oil and the surface or adjacent thereto is maintained at a temperature sufficient to vaporize any water contacting the surface from crude oil to be treated in the dehydrator. It has been found important to maintain a substantially uniform temperature at or below the vaporizing surface in order to effectively treat crude oil for dewatering purposes. Significant temperature fluctuations are typically realized by dehydrators since heat enthalpy is removed in order to vaporize the water in the crude oil. Such fluctuations lead to process complications and upset and are therefore undesirable. The instant invention recognizes this limitation and substantially reduces foaming and provides for a smoothly running and efficient dehydration process.

  • Patent number: 6358398
    Abstract: A method for separating contaminants from a aqueous source containing contaminants. In one embodiment, the method involves the use of a high powdered oxidant dissolved within the aqueous system. The gas is dissolved within a reservoir in the aqueous solution and the pressure within the reservoir is controllable. This allows maximum contact of the oxidizing dissolved gas with the contaminant material. Once oxidized, the outlet of the reservoir is adapted to permit hydraulic cavitation. The net effect of the cavitation is to induce a foam formation which foam transports a floc into a separate phase from the aqueous solution. In this manner, the process is effectively a dissolved oxidizing gas mass transfer process. In another embodiment, the process may be augmented by electrocoagulation. This involves the use of an electric cell which is disposed within the reservoir containing the oxidant material.
