Title: Methode amelioree pour supprimer les reverberations
Inventor: DRAGOSET WILLIAM H JR
IPC: G06F17/00

Granted: 1998-08-11
Abstract: Méthode permettant de réduire les effets de champs d'ondes séismiques bruyants à réverbération enregistrés de l'intérieur d'un milieu chargé d'humidité. Le champ d'ondes se manifeste comme une signature de pression et une signature de vitesse contenant une signature de bruit intégrée. La signature de pression est soumise à un filtrage adaptatif et combinée par soustraction à la signature de vitesse afin d'isoler une signature de bruit quasi-pure. Celle-ci est rajoutée à la signature de vitesse initiale, de signe opposé, afin d'éliminer le bruit intégré et de produire ainsi une signature de vitesse épurée. Celle-ci est itérativement proportionnée et mise en sommation avec la signature de pression, le facteur de proportionnalité étant ainsi incrémenté à chaque itération et la somme, autocorrélée. Un coefficient de convergence est calculé après chaque sommation. Le coefficient de convergence qui se rapproche le plus de l'unité indique le facteur de proportionnalité préféré.

Title: Deblocking the common pathway of aromatic amino acid synthesis
Inventor: FROST JOHN W
IPC: C12P13/04
Filed: 1993-12-09
Granted: 2006-10-31
Abstract: Enhanced efficiency of production of aromatic compounds via the common pathway, as shown in the figure, of a host cell is realized by increasing the expression of enzyme special acting on substrate intermediates in identified rate-limiting reaction steps in the pathway. Host cells are transformed with recombinant DNA encoding for the rate-limiting enzymes to provide cell transformants characterized by capacity to produce high concentrations of aromatic metabolites when grown in call culture with a metabolizable carbon source.

Abstract: The preferred embodiment of the present invention encompasses  an automatic frequency control system implemented  in a radiotelephone (101). The radiotelephone (101) includes a frequency synthesizer. The frequency synthesizer uses a division ratio varied with time by a multi accumulator fractional N division system (140) such that the effective division radio may be varied by non-integer steps. The division radio is programmed to realize the desired channel frequency, the desired channel frequency modulation waveform, and any automatic frequency correction offset. An accurate clock is provided to the control (104) and the user interface (105) sections of the radiotelephone (101) using a second multiple accumulation fractional N division system (139). This second fractional N division system (139) is programmed based on the automatic frequency control programming of the first fractional N division system (140). This lower frequency may then be multiplied in a phase locked loop to provide an accurate reference at a second reference frequency.

Abstract: A method and apparatus for making reusable paint rollers comprised of a core formed from a strip of thermoplastic material. The thermoplastic material is formed into a core by helically winding about a stationary mandril. A layer of adhesive is then applied to the outer surface of the core whereupon a cover is bonded thereto. In a first embodiment the core is formed by winding a plurality of thermoplastic strips about the mandril. In a second embodiment the core is formed by applying liquefied thermoplastic material to a driven belt which transfers the thermoplastic material to the mandril. In yet another embodiment, the paint roller is made by bonding, in a single step, a fabric cover strip to a wound strip wrapped about the mandril.

Abstract: An improved system for connecting and processing a plurality of phone users in a teleconference on a common digital bus. The apparatus includes a plurality of digital processing units (DSPs) associated with selective phone lines and in communication with each other. Each DSP determines an activity status for each associated phone line and transmits that status to the other DSPs. The DSPs create and update respective identical "talk-lists" which reflect the active conferees whose voice data is currently being output on the phone channels. The system thus provides scaleable teleconferencing in a real-time configuration without switching between the various signals on the common bus such that each incoming caller or even a plurality of conferences has equal priority.

Granted: 1999-01-05
Abstract: Emergency lighting housing/canopy interfacing structure.  The structure employs one or more fasteners which may be positioned into place quickly and simply without the aid of tools in order to retain the housing and canopy securely together.  Additional redundance members such as conventional snap-fitting barb members may additionally be employed to assist in installation and for extra safety.  The present invention accordingly provides emergency lighting housing/canopy interfaces which allow simple, quick and reliable installation of emergency lighting fixtures, but which add additional structure to support the housing and the considerable load imparted by transformers, batteries and other structure within the housing.  A preferred embodiment includes an elongated fastener which may be snapped and rotated into place into mounting posts formed on the canopy.          The mounting posts, which protrude into the housing, are thus cammed into place against the housing in order to bias the housing and the canopy securely together.

Abstract: Method and devices for manufacturing biaxially oriented tubing from thermopl astic material. The method comprises forcing the tube over a mandrel (4) at an orientation temperature of the plastic material, wh ich mandrel (4) comprises an expansion part (6) which pr oduces expansion in the circumferential direction of the tube. The forcing over the mandrel is achieved by exerting a pushing force on the tube upstream of the expansion part of the mandrel by means of pushing means (12) acting upon the outside of the tube, and by exerting a pulling force on the tube downstream of the mandrel. The pushing means (12) act upon the tube at a distance upstream of the mandrel, and the tube is supported between the place where said pushing means act and the expansion part of the mandrel.
