Patent CA-2167136-A1 (CA)
Inventor: BELISLE EDOUARD
IPC: A01M23/24
Filed: 1996-01-12
Abstract: Dispositif de retenue dans une position fermée d'un ressort de torsion qui comprend deux branches distinctes se rejoignant en un point de jonction et ayant chacune une extrémité. Ces branches peuvent se déplacer entre une position ouverte où les branches sont écartées l'une de l'autre et une position fermée où les branches sont rapprochées l'une de l'autre. Le dispositif comprend une bague de retenue qui enserre les deux branches et peut coulisser autour de celles-ci, lorsque lesdites branches sont dans la position fermée, entre une position d'attente et une position de retenue, la position d'attente étant située à proximité du point de jonction des branches et la position de retenue étant située à proximité de l'extrémité des branches. Le dispositif comprend en outre un moyen élastique monté sur le ressort entre un point d'appui et la bague de retenue pour amener cette dernière de la position d'attente vers la position de retenue lorsque les branches sont déplacées vers la position fermée. Un tel dispositif est particulièrement utile pour munir les ressorts d'un piège à mâchoire car il permet d'ouvrir les mâchoires du piège avec un minimum de mouvement et sans que les mains soient nécessairement utilisées ce qui représente une système de sécurité dans le cas où un être humain se fait accidentellement piéger les mains par les mâchoires du piège.

Abstract: Traitement anti-acné permettant d'éliminer rapidement les papulopustules de la peau des malades atteints de diverses formes d'acné, de folliculite et d'acné rosacée. Le traitement consiste en une application topique sur la face externe de la papulopustule (bouton) d'une solution aqueuse renfermant de l'eau oxygénée et, de préférence, au moins un acidulant et/ou de l'acide salicylique. L'acidulant préféré est l'acide glycolique. On peut également traiter efficacement les comédons ouverts et fermés par traitement anti-acné à l'aide de la solution aqueuse renfermant de l'eau oxygénée, un acidulant et de l'acide salicylique. La solution contient,de préférence, 3 à 6 % en poids d'eau oxygénée, 2 à 4 % en poids d'acide glycolique, et 2 à 4 % en poids d'acide salicylique, et on l'applique 2 ou 3 fois par jour. Le traitement dure de 1 à 3 jours lorsqu'il est dirigé contre les papulopustules, et de 7 à 20 jours lorsqu'il est dirigé contre les comédons. Le traitement permet également de réduire sensiblement ou d'éviter l'hyperpigmentation et la cicatrisation après la résorption des papulopustules. L'application de la solution d'eau oxygénée dès l'apparition du premier bouton (lésion) empêche l'apparition de papulopustules plus grandes et réduit le risque d'hyperpigmentation et de cicatrisation.

Title: Fuel cells composed of bi-functional catalyst anodes and proton conducting membranes for direct utilization of natural gas and light hydrocarbons
Inventor: OZUM BAKI
IPC: H01M8/22
Filed: 1996-10-17
Abstract: A method has been invented for the production of natural gas fuel cells which can operate by direct utilization of natural gas (methane). These new natural gas fuel cells consist of anodes with bi-functional catalysts, proton conducting membranes and conventional cathodes for oxygen reduction. The catalysts used for the anodes are the catalysts which are used for the oxidative coupling of methane and the catalysts which are used for the hydrogen electrode. The first class of catalysts promote the production of methyl and hydrogen radicals from methane, while the second class of catalysts promote the production of proton from hydrogen radicals. Electric power generation efficiency of these natural gas fuel cells are lower than that of the solid electrolyte natural gas fuel cells, however, they provide co-generation options, i.e., simultaneous generation of electric power, saturated and unsaturated hydrocarbons and/or heat. These new natural gas fuel cells can be designed to operate at low (100 to 190°C) or at high (300 to 650°C) temperatures. These new natural gas fuel cells operating at low temperatures can be used for power generation at remote areas, while the new natural gas fuel cells operating at high temperatures can be used for co-generation. The present invention of natural gas fuel cells can be modified for the direct utilization of saturated and unsaturated hydrocarbon as fuel for the production of electric power and/or hydrocarbons. Therefore, the present invention of natural gas fuel cells can also be used as a chemical plant converting methane to saturated and unsaturated hydrocarbons.

Title: Apparatus and method for determining a distance to an object in a field
Inventor: BECK JAMES L
IPC: G01J1/04
Filed: 1995-07-14
Abstract: An optical proximity sensor (1) generates information indicative of a distance (DI) to an object (14A) in a field and in some embod-iments also generates information indicative of a spectral reflectance characteristics of the object (14A). The information indicative of the spectral reflectance characteristic can be used to determine whether the object (14A) in the field is a living plant (14A) or another object such as soil (10). Light emitted from the optical sensor (1) for reflection off the object (14A) is modulated so that reflected light from the optical sensor can be discriminated from reflected ambient sunlight. The opti-cal sensor (1) is scanned over the field to map objects in the field and/or to determine the location of rows of crop plants. A sensor in accor-dance with the present invention has many uses in agriculture including spraying, cultivation and vehicle guidance.

Filed: 1997-01-21
Abstract: A triple mode aircraft which can take off as a helicopter, or in gyrocopter mode with no power to the rotors or as a conventional aircraft obtaining lift from a circular wing and in another embodiment from short stub wings; a canard wing and high lift tailplane. So it combines the flexibility of a helicopter with the same efficiency and safety of a gyrocopter and a fixed wing aircraft, also has the same simplicity and efficiency of flying a helicopter that doesn't have a tail rotor to worry about. The rotor craft includes two counter-rotating rotors with weighted tips on one set of rotors or a circular airfoil (CA) attached to at least one set of rotors. This CA gives the lift to function as a conventional aircraft, it also weights the tips of the rotor to give a gyro-stabilizing effect to the whole aircraft. Also there is a down draft rudder that functions as a rudder in horizontal flight or catches the down draft from the rotors for directional control. There is a conventional horizontal tail with elevator controls which can be differentially operated for additional control.

Title: Method and device for on-line regeneration of signals transmitted by wavelength division multiplex solitons via synchronous modulation and optical telecommunications system using said method
Inventor: DESURVIRE EMMANUEL
IPC: H04B10/299
Filed: 1997-01-22
Abstract: The method involves performing recovery of a clock signal from a WDM signal and synchronous modulation of solitons at the recovered clock rate. The distance between the transmitter and a first modulator or between successive modulators along the optical link is calculated to ensure the synchronism of different wavelength signals. The regeneration of solitons on the line is controlled by the synchronous modulation of solitons using an optical modulator, recovery of the clock signal and multi-channel filtering at the modulator output. Lengths of fibre with different dispersions can be positioned in the link to manage dispersion along the whole channel.

Abstract: A variable  speed  power  transmission  apparatus comprises an  epicycle  reduction  gear  device  that  has planetary gears whose shafts are supported at equal intervals taken circumferentially thereof by carriers fixed to an output  shaft  thereof,  the  planetary gears  being meshed between external teeth of a sun gear fixed to an input shaft connected to a drive source and internal teeth of a ring gear, and a variable speed hydraulic driver system that is driven by an oil pressure generated by a power of the drive source in such a way as to be variably and reversibly rotated by the oil pressure.  An output shaft of the variable speed oil pressure driver system is connected to the ring gear in interlocking relation therewith to thereby cause forward rotation, reverse rotation or stoppage of the ring gear by the variable speed hydraulic driver system.  Whereby, non-step change is made of the speed of the ring gear.  Since the invention  has  been  constructed  as  mentioned  above,  the invention makes it possible to obtain a variable speed power transmission apparatus which enables highly efficient non-step change in the rotation speed thereof over a wide range of rotations numbers without being increased in size and in cost.
