Title: Food product dressings and methods for preparing food product dressings
Inventor: GAONKAR ANILKUMAR GANAPATI
IPC: A23L27/60
Filed: 1999-02-26
Abstract: The present invention provides oil-in-water emulsion food product dressings and a method for preparing oil-in-water emulsion food product dressings. The method achieves an increase in the viscosity and, hence, the stability, of the food product dressings, which permits the food product dressings to achieve a desired level of viscosity with the use of smaller quantities of oil. This advantageously permits the production of oil-in-water emulsion food product dressings at a reduced cost.

Abstract: An automatic cooking control method for a microwave oven using data pattern of food, including the steps of: (a) collecting data outputted from a data detecting section for a predetermined time; (b) comparing the collected data with at least one prestored data pattern; and (c) selecting the data pattern among the prestored data pattern that is most similar with the collected data, and performing a cooking operation corresponding to the selected data pattern. When the data collected for the predetermined time corresponds to a no-load pattern, the microwave oven stops the cooking operation. Without separate external data input about weight or physical status of the food in the cooking chamber, the microwave oven automatically selects the most proper cooking process for the food in the cooking chamber by comparing the data about the food in the cooking chamber with the data patterns of the various foods prestored in the microwave oven. Accordingly, the microwave oven becomes easy to operate, and the cooking quality of the microwave oven is improved. Further, by regularly repeating the data collecting, data pattern comparing, and data pattern selecting processes, the microcomputer can perform the proper cooking operation while adjusting the cooking operation in accordance with the respectively selected cooking operations.  Thanks to the regular repetition of the above processes, the microwave oven can perform the most proper cooking operation in accordance with the present status of the food in the cooking chamber.

Abstract: The invention relates to a method to inhibit bacteria from adhering to a submergible surface. The method contacts the submergible surface with an effective amount of at least one amino methyl phosphonic acid or salt thereof to inhibit bacterial adhesion to the submergible surface. The invention also relates to a method for controlling biofouling of an aqueous system. This method adds an effective amount of at least one amino methyl phosphonic acid or salt thereof to inhibit bacteria from adhering to a submerged surface within the aqueous system. This method effectively controls biofouling without substantially killing the fouling organisms. The amino methyl phosphonic acid used in the methods of the invention has the formula R1R2NCH2P(O)(OH)2. In this formula, R1 and R2 are independently a C6-C20 alkyl group or a CH2P(O)(OH)2 group.  However, R1 and R2 are not both a CH2 P(O)(OH)2 group.  Alternatively, R1 and R2, together with the N, may also form a 5-8 membered heterocyclic ring having formula (a). In the heterocyclic ring, X is O, NH, or CH2. The salt of an amino methyl phosphonic acid can be an acid salt or a quaternized amino methyl phosphonic acid salt. The invention also relates to a composition containing amino methyl phosphonic acids or salts thereof and useable in the above methods. The compositions comprise at least one amino methyl phosphonic acid or salt thereof in an amount effective to inhibit bacteria from adhering to submergible or submerged surfaces.

Title: Gfci ground fault current filtering
Inventor: ZARETSKY AL
IPC: H02H3/33
Filed: 2000-02-29
Abstract: A system for controlling the response of a ground fault circuit interrupter in the presence of random leakage currents due to the presence of a conductive media such as water or ice. The signal from a magnetic core differential transformer is applied to two filters in parallel. The first filter passes the fundamental frequency of the source and the second filter passes a broad band of frequencies starting at twice the fundamental frequency. The output of the filters are applied to a microprocessor which manipulates the filter outputs and compares certain of the filter outputs to a stored pattern of expected current leakage. The microprocessor operates a relay to disconnect the load from the source when a fault condition exists.
