  • Patent number: 6616892
    Abstract: This invention deals with a process for treating and sanitizing animal habitats. In addition to sanitizing the habitat the production of ammonia and odor from fecal matter and urine is inhibited or terminated. In the process an animal habitat is cleaned and subsequently treated with trichloromelamine (TCM). The TCM may be applied by spraying the habitat with a solution of TCM, by dusting the habitat with powdered TCM or by treating bedding/litter with TCM. This process produces healthier animals and as such the productivity of a given grow out is increased. The process of this invention is particularly suited to animal habitats which are used to raise batches of hogs, cattle, turkeys and chickens on a continuous basis.

  • Publication number: 20030162755
    Abstract: Halo active aromatic sulfonamide organic compounds have been known for over one hundred years. The ability of these compounds to releaser active halogen ions has been utilized in a range of biocidal and fungicidal applications. The most widely used sulfonamide organic compound for these applications has been Chloramine T. This invention deals with nearly discovered halo active aromatic sulfonamide organic compounds and uses of these compounds as biocides, odor control agents, bovine teat cleaners, drugs for cultured fish, soap biocides, stain removal agents, and paint fungicides.

  • Publication number: 20020131950
    Abstract: The disclosure of this invention relates to odor control and more particularly, to a process and composition whereby household, institutional and industrial odors are eliminated wherein these odors are incorporated in a variety of substrates or are emitted from industrial sludges. The odor control composition of this invention is a solution of Chloramine-T which may incorporate a suitable wetting agent. The solutions in this invention may further be buffered. The concentration of the Chloramine-T can be from about 0.5 to about 15 weight percent when used. The concentration of the wetting agent can be from about 0.1 to about 5%.

The process of this invention is particularly suited to animal habitats which are used to raise batches of hogs, cattle, turkeys and chickens on a continuing basis. The TCM may be further incorporated into water soluble polymeric compositions which permit the TCM to be leached out in a controlled manner. Further the TCM may be incorporated into cellular and noncellular polymeric compositions which may be used as bedding/litter material, and cat litter.

  • Patent number: 6404500
    Abstract: The disclosure of this invention relates to calorimeters and a process for operating a colorimeter. The colorimeter of the disclosure is controlled by a microprocessor which evaluates a predetermined radiation absorption curve for each sample. This is to be contrasted with the prior art wherein the test on a given sample evaluates only radiation absorption concentration points which are evaluated by the microprocessor. The colorimeter gives more accurate readings as a result of the fact that an absorption curve and its parameters are evaluated for each sample. The calorimeter uses multiple LEDs as a radiation source. The microprocessor further controls other functions of the colorimeter. A separate microprocessor may be used to control these other functions. The calorimeter and process of this invention are also useful in the analysis of samples for turbidity.

  • Patent number: 6391568
    Abstract: The present invention provides a method for the quantification and assessment of platelet activation in whole blood samples and monitoring of antiplatelet pharmacologic agents. The method for quantifying platelet activation includes exposing platelets to a physiological concentration of an agonist that activates some of the platelets, resulting in the formation of at least one binding site on the surface of the activated platelets, and measuring the activated platelets. The present invention provides a method of assessing specific components of platelet activation.
