Title: Acoustic emission method for sonars
Inventor: GRALL GEORGES
IPC: G01V1/145
Filed: 1995-12-15
Abstract: An acoustic emission method for sonars is described. The method comprises providing the sonar with a transmission antenna (303) separate from the reception antenna (301). The transmission antenna is shaped as a linear acoustic antenna and can be towed together with a reception linear acoustic antenna, or be suspended from a helicopter (202) to form a dipping type sonar (221). Sensing by such sonars is facilitated by increasing the sound level by the directivity index, while the levels of reverberation from the sea floor and the surface of the sea are reduced.
Patent CA-2210196-A1 (CA)
Inventor: MIYATA MINORU
IPC: H04N7/01
Filed: 1997-07-11
Abstract: A video signal converter converts a video signal to a required form. The required form of the signal is the display format for displaying the signal. The input signal is converted to a digital signal and stored in a memory using the output of a first clock pulse generator synchronized to the horizontal synchronizing signal of the input signal. The digital signal is read out from the memory using the output of a second clock pulse generator synchronized to the vertical synchronizing signal of the input signal from a position specified by the controller. The output digital signal is then reconverted to an analog signal.

Patent CA-2217079-A1 (CA)
Title: Articulation assembly for surgical instruments
Inventor: HUITEMA THOMAS
IPC: A61B19/00
Filed: 1997-09-26
Abstract: An articulating surgical instrument which has an articulation transmission assembly for remotely articulating an end effector of the instrument is disclosed. Ratcheting rotation of a compressible deck within a detent housing of the assembly from a first locked position to a second locked position causes axial movement of an elongated transmission member for the articulation of the end effector from a first position to a second position angled from the first position. Also disclosed is a flexible neck assembly for articulating the end effector of the surgical instrument.  Neck ribs, each having an interior plate and an exterior dish, extend from a central longitudinal rib separating a pair of flexible neck portions of the assembly. A pair of transmission band assemblies, each having an interior articulation band and an attached exterior reinforcement band, reciprocate in opposite directions within side slots of the neck ribs in response to actuation of the articulation transmission assembly.  Reciprocation causes the flexible neck assembly to bend, effecting articulation. The shape of the neck ribs optimizes the radius of curvature when articulation is effected, and the reinforcement bands prevent buckling of the articulation bands.
Patent CA-2217457-A1 (CA)
Title: A method for processing gold-bearing sulfide ores involving preparation of a sulfide concentrate
Inventor: SIMMONS GARY L
IPC: C22B1/00
Filed: 1996-03-22
Abstract: Provided is a method for processing a gold-bearing sulfide ore (102) which involves maintaining the ore in a substantially oxygen-free environment, preferably beginning with comminution of the ore and ending when a desired final concentrate (116), enriched in sulfide minerals, is obtained by flotation. In one embodiment, nitrogen gas (110) is used to substantially prevent contact between the ore and air during comminution (104) of the ore and during flotation (112) operations. It is believed that oxygen gas present in air detrimentally affects the recovery of sulfide minerals in a flotation concentrate through surface oxidation of sulfide mineral particles. The use of a gas such as nitrogen can significantly reduce the potential for such surface oxidation. Additionally, gases separated from an oxygen plant may be beneficially used, with an oxygen gas stream being used, for example, for pressure oxidation of sulfide mineral materials, and with a nitrogen gas stream being used in comminution and/or flotation operations, resulting in advantageous use of a nitrogen gas by-product stream which has previously been vented to the atmosphere as waste.

Title: Stationary exercise device
Inventor: PASERO PETER
IPC: A63B21/22
Filed: 1997-06-26
Abstract: An exercise device includes a pair of foot engaging links (30a, 30b). The rearward ends of the foot links are supported for rotational motion about a pivot axis (26), and the forward ends of the foot links reciprocate back and forth along a guide (36). The combination of these two foot link motions permits the users feet to travel along an elliptical path of travel. The inclination and/or elevation of the guide (36) may be selectively altered to vary the nature of the stepping motion experienced by the user. At tower inclinations/elevations of the guide, the stepping motion may resemble cross country skiing. At progressively higher angles of inclination or elevations of the guide (36), the stepping motions may simulate walking, jogging running and climbing. The connection of the foot links to the pivot axis allow motion in a direction orthogonal to the rotational motion, thus compensating for alignment inconsistencies of the device.

Filed: 1996-09-04
Abstract: Système de compression-extension multivoie synchrone pour prothèses auditives, dans lequel le signal d'entrée en provenance d'un transducteur d'entrée est dirigé via un compresseur d'entrée 2:1, puis via un filtre passe-bande qui le divise en un nombre voulu de bandes de fréquence, puis via des unités d'extension-compression assurant l'extension-compression de chaque bande de fréquence en fonction du handicap auditif de l'utilisateur. Les sorties des unités d'extension-compression sont additionnées, amplifiées et dirigées vers le transducteur de sortie de la prothèse auditive. Le compresseur et chaque unité d'extension-compression sont commandés par des signaux de commande dérivés du niveau de signal comprimé à la sortie du compresseur avant. L'utilisation de signaux de commande communs pour la compression et l'expansion frontales supprime la nécessité d'une adaptation temporelle précise des signaux produits et améliore la fidélité du signal de sortie. Le compresseur frontal permet l'utilisation de condensateurs filtres de dimension réduite, qui peuvent être intégrés. Les sons situés au-dessus d'un seuil haut ne modifient pas le gain appliqlué au signal d'entrée, même lorsque des changements sont opérés dans les rapports extension-compression des unités d'extension-compression.
