Title: Method and system for processing the preechos of an audio-digital signal coded by frequency transformation
Inventor: MAHIEUX YANNICK
IPC: H04B1/66
Filed: 1992-03-25
Abstract: ABSTRACT            METHOD AND SYSTEM FOR PROCESSING THE PREECHOS OF AN AUDIO-DIGITAL SIGNAL CODED BY FREQUENCY TRANSFORMATION     The invention relates to a method and a system for processing the preechos of an audio-digital signal coded by frequency transformation.        The method and the system,  after coding said signal by frequency transformation as a coefficient y(k), over weighting windows formed over blocks of samples x(n) comprising N successive samples, make it possible to perform, on decoding the transform coefficients y(k), an optimal filtering of KALMAN filtering type,  so as to reduce, when in the presence of a transition in amplitude of the signal, the resulting additive noise when coding the quantization of the transform coefficients.  Application  to  the  processing,  storage  and transmission  of  high-fidelity  quality  audio  digital signals.            (figure 2)

IPC: G01V1/30
Filed: 1991-06-10
Abstract: A method for tracking seismic events such as boundaries of formation layers of earth formations is disclosed. Especially adapted for tracking such events in a two-dimensional slice of 3-D seismic volume data, the method begins by designating a starting data point on the seismic event. The method tracks such event through the grid of data by sequentially establishing areas or "tiles" of data about the starting point. The tiles are defined by data points of the grid. Each of the data points is then tested to see if it meets an acceptance criterion for the seismic event. Such data points of the tile are stored as identifying the seismic event only if certain of the data points of the tile pass the acceptance citerion. Next, each of the data points of a previously accepted tile are used as a starting data point about which a new tile is defined. The process is repeated until no more tiles are available for testing. The accepted data is then displayed so as to distinguish the accepted data from other data of the grid thereby identifying the seismic event to seismic interpretation specialists.

Abstract: This disclosure is directed to a novel shoe tongue construction wherein the tongue is made as an integral extension of preferably the heel portion of the shoe.  The tongue may also be an integral extension of the quarter.  The tongue construction provides greater comfort to the wearer of the shoe than do conventionally mounted tongue constructions because the tongue is integrally formed with either the counter or the quarter of the shoe rather than being stitched to the vamp.  This construction is also more economical to make because cutting and stitching requirements are reduced.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a method of crystallizing (1R,5S,6S)-2-[(6,7-dihydro-5H-pyrazolo[1,2-a][1,2,4]triazolium-6-yl)]thio-6-[(R)-1-hydroxyethyl]-1-methyl-carbapenem-3-carboxylate (herein-after simply referred to as L-627), by maintaining an aqueous solution of L-627 at a temperature in the range from the eutectic temperature of the solution to a temperature lower than 0°C.  The method provides such advantages that loss of L-627 accompanied by crystallization is reduced, the number of steps in the preparation of vial formulations is small and maintenance of these steps under sterile and dust-free conditions can be per-formed easily, dispensing of the drug can be conducted with quantitative accuracy, and the crystals promptly dissolve in a solvent at the time of use.

Title: Label printing and data collection program generator
Inventor: LAMPRECHT DALE E JR
IPC: G06F3/12
Filed: 1993-04-08
Abstract: A program generator allows a user to create a software program capable of being executed by a remote labeler to control the printing of one or more labels and to control data collection operations thereof. The program generator stores a user entered sequence of commands selected from a set of commands that control label printing and data collection operations. The stored sequence of commands is validated in accordance with the program generator such that each command entered by the user is compared to a set of allowable commands to determine whether the command is valid or not.      During the validation of each of the commands, the program generator determines whether the parameters of the command define allowable data manipulation operations to be performed by the labeler. If not, the program generator provides an error message that identifies the particular command and the error associated with the command. The program generator allows various application files to be selectively linked together to form an application program.      Further, when downloading an application file to a labeler, the program generator automatically determines whether the application program requires a look-up file. If so, the program generator creates the necessary look-up file.

IPC: H01J9/02
Filed: 1993-06-03
Abstract: A high pressure discharge lamp with a thermally improved anode, as well as a method of making such a lamp, are disclosed. The lamp includes a refractory arc tube with a hermetically sealed arc chamber, a fill in the arc chamber for facilitating light generation, and an anode and a cathode extending into the hermetically sealed arc chamber and being spaced apart from each other. The anode comprises a shank of refractory metal, a cylindrically shaped refractory metal sleeve on a portion of the shank, and an end proximally facing the cathode. The anode end comprises a substantially solid mass of refractory metal, and is integrally joined to both the shank and the metal sleeve to facilitate heat flow from the anode end to the shank and sleeve. The anode end preferably is generally shaped as a hemisphere facing the cathode. The fill may comprise mercury, metal halide, and xenon at a relatively high fill pressure.      The anode may be formed by, first, providing a refractory metal shank and placing a refractory metal sleeve, e.g., one or more layers of a helically wound refractory metal wire, along a portion of the shank, to form a sleeve-shank combination. A portion of the sleeve-shank combination facing downwards, is then heated sufficiently to cause metal from the sleeve-shank combination to ball up and form an anode end that integrally joins both the shank and the metal sleeve. The heating is preferably sufficient to cause the anode end to ball up into a generally hemispherical shape.
