Granted: 2007-10-30
Abstract: The invention relates to a feeding machine for feeding flat, flexible, conveyed goods (3), especially envelopes, said goods being arranged in stacks (2), into a station for further individual handling. The aim of the invention is to provide a feeding machine of this type which is very reliable, even at high operating speeds. To this end, a stack of goods being conveyed is fed in via a cocked supply channel and transformed into a layered stream of conveyed goods by an arrangement of two conveyor belts (10, 13), said arrangement operating at an angle going upwards from the base of the stack and then horizontally, together with a stripper (21). This layered stream of conveyed goods exits onto a transfer table (12), where detectors (38, 39) control the movement of the stream onto a removal device (30) in such a way that said removal device can remove individual items from the layered stream of conveyed goods at regular intervals.

Abstract: An adjustable height fill valve for controlling the water level in a storage tank for a toilet includes a riser mounted in the tank and connected to a pressurized water supply. The riser includes an anti-siphon body telescopically mounted over a fixed shank. The anti-siphon body telescopically adjusts between retracted and extended positions. A pilot valve is mounted on the anti-siphon body in fluid communication with the water supply. A float is mounted in association with the pilot valve to selectively open or close the pilot valve depending on the water level in the tank. A latch on the anti-siphon body and a series of stops on the shank are releasably engageable to adjustably fix the position of the body on the shank between the retracted and extended positions. The stops comprise first and second sets of axially spaced and interleaved forgers which define a serpentine track into which the latch extends.

Abstract: A source signal (e.g. a voice test) is processed by a voice coder or transmitted and converted into a receive signal (coded voice signal). The source and receive signals are separately subjected to preprocessing and to psycho-acoustic modeling, followed by internal calculation to evaluate the similarity of the signals. Finally, MOS calculation is carried out to obtain a result that can be compared with human evaluation. According to the invention, a spectral similarity value is determined for evaluating transmission quality, which is based on calculating the covariance of the spectra source and receive signals and dividing the covariance by the standard deviation of the above mentioned spectra. The inventive method enables objective evaluation (voice quality forecast) while taking into account the human hearing process.

Title: Transformateur haute tension
Inventor: DIAZ CARMENA ANGEL
IPC: H01F38/16
Filed: 1999-11-25
Granted: 2008-01-29
Abstract: L'invention concerne un transformateur se composant d'éléments classiques disposés en deux groupes distincts, d'une part les éléments à potentiels positifs (1-5) et d'autre part les éléments à potentiels négatifs (1'-5'), tous deux étant séparés par une seule barrière isolante (6). Une des extrémités des éléments présente un potentiel de référence qui tend à augmenter progressivement vers l'extrémité opposée dans le cas des éléments à potentiels positifs et qui tend à diminuer progressivement dans le cas des éléments à potentiels négatifs. Ainsi, à un même potentiel ou à une différence de potentiel par rapport à la référence, les éléments de chaque groupe sont équipotentiels. Cette structure annule les capacités parasites et permet de placer les éléments de chaque groupe à proximité immédiate, réduisant ainsi considérablement le volume et, de ce fait, le coût.

Abstract: The present invention provides a method for creating amorphous patterns based on a constrained Voronoi tesselation of 2-space that can be tiled. There are three basic steps required to generate a constrained Voronoi tesselation of 2-space: 1) nucleation point placement; 2) Delauney triangulation of the nucleation points; and 3) polygon extraction from the Delauney triangulated space. The tiling feature is accomplished by modifying only the nucleation point poriton of the algorithm. The method of the present invention, for creating an amorphous two-dimensional pattern of interlocking two-dimensional geometrical shapes having at least two opposing edges which can be tiled together, comprises the steps of: (a) specifying the width x max of the pattern measured in direction x between the opposing edges; (b) adding a computational border region of width B to the pattern along one of the edges located at the x distance x max; (c) computationally generating (x, y) coordinates of a nucleation point having x coordinates between 0 and x max; (d) selecting nucleation points having x coordinates between 0 and B and copying them into the computational border region by adding x max to their x coordinate value; (e) comparing both the computationally generated nucleation point and the corresponding copied nucleation point in the computational border against all previously generated nucleation points; and (f) repeating steps (c) through (e) until the desired number of nucleation points has been generated.      To complete the pattern formation process, the additional steps of: (g) performing a Delaunay triangulation on the nucleation points; and (h) performing a Voronoi tessellation on the nucleation points to form two-dimensional geometrical shapes are included. Patterns having two pairs of opposing edges which may be tiled together may be generated by providing computional borders in two mutually orthogonal coordinate directions.
