Patent GE-P20115271-B (GE)
Title: Turbine
Inventor: AMIREDZHIBI SHALVA
IPC: F03D5/06
Filed: 2009-03-23
Abstract: A turbine contains a case with the shaft 6 placed in it, which is connected with the blades 1 mounted with equal distances between each other in a plane perpendicular to its axis. Thus, in the case having the streamline shape, there are placed linked with each other by belt 8 and 10 or any other transmission the crank-and-rod mechanism which rotates the shaft and the mechanism for rotation of the blade or step-by-step disposed blades. With the purpose of creation of the necessary moment, the point of pivot connection of mobile sliding bar 2 placed in the guide 3 of the crank-and-rod mechanism 5 and 4 with the blade is removed from the point of the application of the excited hydroaerodynamic force on the blade by an eccentricity ε. And the blade by the groove or a protuberance is in turn in contact to cranks 12 and 13 of the mechanisms of rotation of the blades about dead points A and B of the crank-and-rod mechanism. Thus, the rotation of the blade is fixed by the stops 14.

Title: Aerated liquid storage/dispensing apparatus
Inventor: BALL MARTIN F
IPC: B67D1/04
Filed: 1986-09-23
Granted: 1990-11-06
Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for storage and dispensing of carbonated beverages or the like liquid.  The extent of aeration of the liquid is maintained as the volume of the liquid in the tank decreases.  The storage apparatus includes a vessel containing low-pressure gas.  The tank and the vessel are interconnected via a pressure regulator.  The regulator delivers the gas from the vessel to the tank at a constant pressure which is consider-ably lower than that under which the gas is kept in the vessel. The dispensing of the liquid from the tank takes place simultan-eously with the inflow of the gas from the vessel.  The invention enables storage of liquids such as fizzy drinks and its dispensing, without progressive loss of "fizz" or "sparkle".

Title: Continuous speech recognition apparatus

IPC: G10L15/07
Filed: 1987-02-17
Granted: 1992-09-29
Abstract: ABSTRACT    A start point vicinity of an uttered input speech pattern is set.  DP-matching is performed between the input speech pattern and a plurality of reference patterns obtained by connecting previously prepared reference patterns in the start point vicinity or a portion for the head word of the input speech pattern.  A point within the start point vicinity is determined as a temporary start point.  The dissimilarity proportional to the time length of the reference pattern is calculated and then converted into a value proportional to the time length of the input pattern from the temporary start point.  The dissimilarity measure between the input speech pattern and the reference pattern on the second and the following digits are determined as a value proportional to the time length of the input speech pattern.  The end time point of the input speech pattern is determined on the basis of the minimum value of a normalized dissimilarity measure by the time length of the input speech pattern.

Abstract: ABSTRACT            The invention provides a method of making a cathode suitable for an electrochemical cell of the type having a molten sodium anode, a beta"-alumina separator, a cathode which comprises one or more transition metals selected from the group comprising Fe, Ni, Co, Cr and Mn.  The method comprises heating a particulate starting material comprising at least one member of said group of transition metals in an oxidizing atmosphere to cause its particles to become at least partially oxidized, and to adhere together to form a unitary porous matrix.   This matrix is then heated in a reducing atmosphere at least partially to reduce the oxide formed during the formation of the matrix, and the reduced matrix is then impregnated with a sodium aluminium chloride molten salt electrolyte.  Sodium chloride in dispersed form is incorporated into the matrix, preferably by mixing sodium chloride in particulate form with the particulate transition metal starting material, before the heating in an oxidizing atmosphere to form the matrix.

Abstract: ABSTRACT OF THE DISCLOSURE     In a process for the fast cooking of pasta and the like, a metered quantity of food is introduced, from the top, into a containing chamber (8) embodied in a boiler (7), in said containing chamber (8) pasta being homogeneously distributed. Subsequently water at high pressure and temperature coming from boiler (7) is also introduced into the containing chamber (8). The expansion of water in the containing chamber (8) takes place without forming overheated vapour so that water can homogeneous-ly impregnate and soften pasta within a period of time shorter than 40 seconds. Pasta is then conveyed into a pause chamber (9) where cooking goes on for a period of time shorter than 40 seconds. The last cooking operation takes place in the consuming vessel (76) where pasta is finally transferred, while the final consumer is putting dressing thereon.

Abstract: COMBINATION WEIGHING METHOD AND APPARATUS                  USING MULTI-BIN SCALES                 ABSTRACT OF THE DISCLOSURE          A combination weighing machine produces a weight of product closely approximating a target weight by selecting a combination of lesser weights from a plurality of weigh scales and discharging the selected combination into a container or packaging machine.  Each weigh scale has multiple bins for weighing and discharging multiple quantities of product respectively, and a single weight sensor.  The weight of product in each bin is determined separately by delivering product to one bin at a time and measuring the change in the aggregate weight of product on the scale after each delivery.  The weights determined for each bin are stored and are used in searching for and selecting an acceptable combination for discharge.

Title: Oxidation process
Inventor: TURNER PHILIP J
IPC: B01J19/12
Filed: 1987-09-04
Granted: 1990-12-11
Abstract: ABSTRACT                     Oxidation Process Oxidation of alcohols to ketones using bromine suffers from a side reaction of comparable speed in which a bromide substituted product is formed. Additionally, the use of bromine as reagent is relatively unpleasant and it creates a major waste disposal problem.    The latter problem can be solved by generating bromine in situ by reaction between hydrogen peroxide and bromide ions or hydrogen bromide, but this inevitably increases the exposure of the alcohol to HBr/Br-.The selectivity of the process towards non-substituted oxidation depending upon the inherent deactivation or reactivity of the alcohol can be improved by irradiating the reactants with light of suitable frequency to generate bromine radicals in the mixture, and/or by controlling the rate of introduction of the hydrogen peroxide and controlling the extent to which mole ratio of HBr:alcohol is substoichiometric.  Selectivity can also be improved by employing a two-phase reaction mixture, the alcohol being present to a considerable extent in the organic phase with HBr/Bromide being retained to a great extent in the aqueous phase.      It is particularly beneficial for the selective oxidation of alcohols that are substituted by adjacent electronegative groups, for example chloropropanols.

Abstract: A B S T R A C T      The invention relates to a process for leaching gold and/or silver from ores or ore concentrates using an aqueous alkaline cyanide solution with addition of hydrogen peroxide.     The industrial application of this process has hitherto been hampered by its lack of economy, i.e. the consumption of H2O2 and NaCN was too high.   According to the invention, it has been found that the process can be made very economical and that disadvantages of the conventional leaching process can be avoided if the addition of the aqueous H2O2 solution is regulated through the concentration of the oxygen dissolved in the leaching solution, the leaching solution containing from 2 to 20 mg O2 and preferably from 7 to 13 mg O2 per liter.   0.5 to 5% by weight H2O2 solutions are preferably added.     The process is applicable both to leaching by agitation and to heap leaching, the addition of H2O2 being regulated through measurement of the O2 concentration in a measuring stream.   Despite low consumptions of H2O2 and NaCN, the gold yield is even increased in some cases and the leaching time shortened.
