Patent CA-2291447-A1 (CA)
Title: Dual operator phase control engine driven welder
Inventor: BUNKER THOMAS
IPC: B23K9/10
Filed: 1999-12-02
Abstract: A method and apparatus for providing welding power includes two power sources (first and second), each having an output. A linking circuit selectively connects the power sources in one of an independent mode (such that each is connected to a separate welding output whereby the first welding output is independent of the second welding output) or a combined mode (such that the power sources are connected in parallel and connected to one welding output whereby the outputs of the first power source and second power source are combined). A controller includes a mode selector to allow the user to select between the independent mode and the combined mode. Also, the controller includes a master output magnitude selector, which is a single selector, that controls the magnitude of the output of both power sources when the user has selected the combined mode.      The power sources can be operated in a CV or CC mode when independent, or a CC mode when combined. A load compensation circuit compensates for the voltage droop in the output of the generator.

Patent CA-2297659-A1 (CA)
Inventor: SHENNIB ADNAN
IPC: H04R25/02
Filed: 1998-07-07
Abstract: An acoustic coupler is detachably secured to a receiver assembly for deep insertion into an individual's ear canal. The acoustic coupler provides a semirigid, thin walled, cylindrical coupling sleeve that is adapted to be attached over a cylindrical receiver assembly. A conforming sealing material is attached diametrically over the coupling sleeve to fit comfortably and to seal the individual's ear canal acoustically. The coupling sleeve is substantially concentric to the receiver assembly for a highly space efficient interface and a user friendly replacement method. Attachment of the acoustic coupler to the receiver assembly is accomplished by applying a minimal axial (push) force to secure the acoustic coupler to the receiver assembly. The coupler remains securely attached thereto, and can withstand considerable axial detachment (pull) forces without being dislodged within or outside the ear canal. Applying a rotational (twist) force with respect to the receiver housing detaches the acoustic coupler from the receiver housing. Because rotational movements are minimal during insertion or removal of the coupler from the individual's ear, accidental detachment is not possible.

IPC: E21B34/10
Filed: 2000-04-20
Abstract: A bi-directional plug blocks the flow of fluid through a flow bore of a tubing string and can be opened by simple mechanical means requiring no external tools. A  piston is slidably mounted in a piston housing and fixed in a first position with a plurality of shear screws. An atmospheric chamber formed within the piston housing creates a pressure differential causing the shear screws to fail when a certain pressure is applied to the surface area of the piston. When the shear screws break, the piston accelerates and strikes a scored, dome-shaped plug. The piston penetrates the plug, permanently pressing and housing pieces of the plug against the wall of a plug housing and opening the flow bore of the plug to fluid.

Title: Comfort noise generation for open discontinuous transmission systems
Inventor: BEAUCOUP FRANCK
IPC: G10L19/012
Filed: 2000-11-20
Abstract: A Comfort Noise Generation (CNG) system is provided for use in open systems where there is no predefined protocol for transmission of Silence Insertion Descriptor (SID) information from transmitter to receiver. The receiver enters an underrun condition in response to periods of silence, and in response generates comfort noise. According to the present invention, the computation of the level and spectral characteristics of the background of the speech signal is done within the receiver, thereby overcoming the lack of a protocol to transmit the SID information during silence periods. These characteristics are computed as a gain parameter and a set of Linear Prediction Coding (LPC) parameters which are applied to a filter which filters flat-spectrum noise in order to generate noise that sounds like the background noise of the speech signal.

Title: Dispositif pour proteger contre les piqures d'insectes sans modifier l'equilibre ecologique
Inventor: STOLL KURT
IPC: A01M29/00
Filed: 1999-04-27
Abstract: L'invention concerne un dispositif permettant de protéger contre les piqûres d'insectes, sans modifier l'équilibre écologique. Selon l'invention, un module (1) monté par exemple dans la base (31) d'une montre-bracelet (30), comprend deux oscillateurs produisant des oscillations de différentes fréquences, qui transforment par l'intermédiaire de deux antennes corporelles (6, 7) les oscillations produites par rapport à la surface de la peau d'un individu. Les deux oscillations se superposent et se propagent sous forme d'ondes de surface sur l'ensemble de la surface de la peau. Les moustiques femelles hématophages qui viennent prélever leur nourriture chez des mammifères et chez l'homme, pompent du sang par leur trompe dans le derme irrigué. A cette fin, les moustiques viennent au contact de la surface de la peau sur laquelle les ondes de surface se superposent. Les sensilles extrêmement sensibles, qui sont réparties sur l'ensemble du corps des insectes, de manière néanmoins renforcée en des points déterminés, savoir les palpes, les rostres et les pattes, réagissent aux oscillations superficielles adaptées à leurs fréquences de résonance. Les oscillations sont converties par les cellules sensorielles qui contiennent des récepteurs de stimuli biochimiques et mécaniques, en courants de stimulation, qui sont acheminés de manière correspondante jusqu'au ganglion de la zone pharyngée supérieure (cerveau des insectes) par l'intermédiaire du système nerveux. Les informations obtenues sont transmises au système moteur musculaire par l'intermédiaire du système nerveux qui forme le ganglion de la zone pharyngée supérieure, conjointement avec ses ganglions. Ces informations induisent notamment le processus de commande de la trompe du moustique. Ledit moustique se trouve de ce fait dérangé dans ses intentions, savoir pomper du sang, et s'éloigne de la surface de la peau.
