Title: Preparation of ammonium glyphosate using aqueous ammonium hydroxide in a solid reaction system
Inventor: LINDEMANN RALPH E JR
IPC: C07F9/38
Filed: 1996-03-05
Abstract: Solid N-phosphonomethylglycine or glyphosate acid is charged to a substantially closed system and then partially pre-dried as by continuously recirculating it through a hot air grinding/drying system. A cooled solution of ammonium hydroxide is then metered into and reacted with the partially dried glyphosate acid as it is being recirculated in a manner such that the moisture content of the reaction mass so formed is continuously decreased throughout the reaction. Following completion of the ammonium hydroxide addition, a powdered reaction mass/product having a moisture content of about 2 wt.% is formed. Significantly, at this stage, the ammonium glyphosate product is suitable for end use and it can be readily dissolved in water and immediately used as a herbicide or plant growth regulator. More importantly, however, this product is capable due to its highly sorptive character to be further formulated into a product exceptionally highly loaded with adjuvants and particularly surfactants.
Patent CA-2221384-A1 (CA)
Inventor: LEPPER JAMES M JR
IPC: A61B5/1455
Filed: 1996-06-04
Abstract: L'invention se rapporte à un système (100) de contrôle de la glycémie, qui fait appel à une source lumineuse à large bande (110) et à un filtre optique (120) de fabrication spéciale permettant de moduler les rayonnements optiques à transmettre dans un support charnu. Les rayonnements optiques (125) qui traversent le support charnu (130) sont détectés par un détecteur optique (140) qui génère un signal électrique indiquant l'intensité de la lumière détectée. On applique un traitement de signal numérique aux signaux électriques afin de déterminer les caractéristiques optiques des signaux électriques imputables aux caractéristiques optiques du filtre et pour isoler par ailleurs les fractions sanguines du support charnu autre que la concentration en glucose dans le sang. On utilise dans ce système une fonction inédite de transformation par "double entrée" afin de réduire au minimum les erreurs dues aux variations indéterminées de la longueur du trajet des rayonnements optiques dans le support charnu. On utilise, en outre, dans le système de contrôle (100), un traitement spécialisé des signaux qui permet d'éviter les imprécisions inhérentes à l'effet de solvant obtenu lorsque le glucose est dissous dans l'eau, qu'il était impossible d'identifier antérieurement.

Title: Antihistaminic substance of stevia origin
Inventor: SATO NAOHIKO
IPC: A01N65/00
Filed: 1998-03-17
Abstract: Disclosed is an antihistaminic substance comprising an extract from a plant tissue of Stevia, which is mainly contained in its stems and leaves, and in an cold water, hot water or lower alcohol extract thereof.  Standing of the extract naturally causes fermentation to separate one or more organic acids such as lactic acid and acetic acid,  thereby more enhancing the action. The addition of at least one organic acid to the extract immediately after extraction can also enhance the action. When rainbow trouts or broilers are fed on diets containing histamine, this extract significantly relieves the action of histamine. The extract also represses symptoms such as flare, itch and pain caused by excessive release of activated histamine or a histaminic substance,  thus providing an antihistaminic substance of natural origin having no side effect.

Patent CA-2244125-A1 (CA)
Inventor: HENDRICKS JUDY K
IPC: C12Q1/22
Filed: 1997-01-22
Abstract: This invention relates to novel apparatus and methods for inserting and positioning a compressible material into a container and for using the container for detecting a specific environmental parameter or combination of parameters and for determining the effectiveness of a sterilization procedure. Precise positioning of a plug of compressible material in a container provides flexibility for production of indicator systems that vary in their response to sterilizing conditions. These indicators reflect the efficacy of sterilizers based on different modes of sterilization and reproduceability for accurate monitoring of each mode. The invention also relates to test indicators containing controlled volumes of compressed, gas-permeable materials and to methods for using test indicators for determining the efficacy of different types of sterilization processes. The test indicator consists of a plurality of interactive enzymes in a container with at least one opening. The opening is filled with a compressed cylindrical foam insert and the test indicator is placed into the sterilization chamber. The foam insert regulates the amount of sterilant such as steam, gas, chemicals or plasma entering the test indicator. Upon proper sterilization, the sterilant destroys the interactive enzymes and no color product is formed. Inactivation of the enzyme system parallels the inactivation of bacterial spores subjected to the sterilization process. Results are available in from a few seconds to a few hours. The test indicator can also be placed into a container with material such that the design simulates an environmental parameter test of the sterilization process.

Abstract: The present invention relates to methods of regulating TNF activity indirectly by regulating the activity or concentration of TNF receptor releasing enzyme (TRRE). Preferably, the TRRE activity is regulated local to the site of the condition to be treated. In the case of diseases associated with elevated levels of TNF, such as rheumatoid arthritis, TRRE is administered to the site of inflammation in an amount sufficient to decrease the local levels of TNF. In the case of diseases, such as cancer, that benefit from increased levels of TNF, the level of TRRE is decreased at the disease site.
