Patent CA-2200705-C (CA)
Title: Dispositif electronique de securite et d'armement
Inventor: BOUCHER CRAIG J
IPC: F42C11/00
Filed: 1995-10-12
Granted: 1999-09-21
Abstract: Un dispositif électronique de sécurité et d'armement a une source interne (12) d'alimentation périodique en énergie de basse tension dont la tension est en soi insuffisante pour allumer le détonateur (18). Le circuit comprend par conséquent un transformateur survolteur (14) qui permet d'obtenir une tension suffisante pour allumer le détonateur (18). Le transformateur survolteur (14) charge un circuit d'armement (16) qui accumule l'énergie de haute tension afin d'allumer le détonateur (18) et qui en outre alimente en énergie le circuit d'allumage (20) qui décharge l'énergie accumulée de haute tension à travers le détonateur (18) au moment approprié pour allumer le dispositif. La source périodique (12) d'énergie de basse tension peut comprendre une batterie de basse tension (120) et un interrupteur dynamique (126) qui fournit des impulsions périodiques d'énergie de basse tension à l'enroulement primaire (140) du transformateur (14). L'interrupteur dynamique (126) peut être alimenté en énergie par la sortie du transformateur (14), de sorte que la batterie de basse tension (120) n'ait pas assez de tension pour alimenter en énergie l'interrupteur dynamique (126). L'énergie de haute tension dérivée de la sortie du transformateur (14) est ainsi requise pour faire fonctionner le circuit, ce qui évite l'allumage du dispositif lorsque le circuit est endommagé.

Structure for controlling the generation of heat is also disclosed. The apparatus may optionally include a spacing or standoff structure which spans the drug formulation reservoir between the non-permeable wall and the user's skin surface for maintaining a predetermined thickness of the drug formulation on the user's skin surface. Also, a novel product formulation which can be used with the apparatus which uses high percentage of eutectic mixture of local anesthetics to reduce the overall degradation rate of the local anesthetic compound(s) in formulations which are subject to hydrolysis.

Abstract: Tuyère réfractaire (1) interdisant de manière efficace l'accumulation de dépôts d'alumine autour de son bord supérieur, où vient s'appuyer la fermeture à bouchon. La tuyère se compose d'un corps de tuyère réfractaire (7) présentant une partie supérieure (9) et une partie inférieure (11). L'alésage (13) traverse la partie inférieure et la partie supérieure, qui comporte une extrémité d'admission et de libération ayant pour fonction d'admettre et de libérer le métal en fusion. Un injecteur de gaz inerte (20) entoure la partie supérieure du corps de la tuyère (7). Une chemise (40) constituée d'un matériau réfractaire faisant écran au gaz recouvre les parois de l'alésage et définit un siège au niveau de la partie supérieure de l'alésage. Un blindage métallique (50) entoure la face externe de la partie supérieure (9). Le gaz inerte sous pression, acheminé vers la partie supérieure, perméable au gaz, du corps de tuyère par le dispositif d'injection de gaz est guidé par la chemise faisant écran au gaz et par le blindage métallique, de sorte qu'il s'écoule essentiellement à travers le bord supérieur de la partie supérieure. Le flux de gaz inerte qui en résulte isole le siège de l'alésage par rapport à l'oxygène du milieu ambiant, interdisant ainsi l'accumulation sur ce siège de dépôts d'alumine risquant d'interférer avec la capacité pour la fermeture à bouchon, de réguler le flux de métal en fusion.

Abstract: The thrust combustion grate is designed for burning refuse. It comprises alternately stationary (5) and movable (6) hollow grate plates (5,6) in a stairway formation, that rest on each other with their front underedge. These grate plates extend across the entire width of the grateway. The movable grate plates (6) are each driven by a hydraulic cylinder-piston unit (18,19). To the sides, the grateway is limited by panels (8,9) comprising water--cooled hollow profiles (8,9), which, in the longitudinal direction, each consist of at least two sections flanged together sealingly.

Running between the panels (8,9) there are two other hollow profiles (10,11) flanged together in the same way, for feeding in primary air and cooling water, which are fixed to certain individual distancing bars (3,4). The back sides of the stationary grate plates (5) each rest on one distancing bar (3) whilst the back sides of the movable grate plates (6) rest on at least one steel roller (16,17) with a horizontal axis, with each side of their front sides being guided along a steel roller (20,21) whose axis runs perpendicular to the grate plate (6). The front portions of the grate plates (6) are transpierced by primary air slots (25).

Title: Drying of atomized metal powder
Inventor: LARSSON RUTGER
IPC: B22F9/08
Filed: 1997-04-18
Granted: 2005-08-02
Abstract: Metal powder, particularly iron/steel powder with low oxygen content, is atomized in an oxygen-free atmosphere by means of a hydrocarbon in liquid form such as paraffin, and the moist powder, still hot (60-80 .degree.C), is transferred to a container (1) and supported therein on a screening member (2). A negative pressure is first applied below the screening member (2) so that liquid is drawn from the powder mass. An inert gas, substantially free from oxygen, is then circulated through the powder mass, whereupon vapour absorbed by the gas is condensed before the gas is recirculated to the container (1). A circulation circuit (70) for liquid atomizing medium joins the gas-circulation circuit (20) at a liquid jet pump (30).

Les moyens de verrouillage (17, 20) sont placés sur la tête du piston (7), prés d'une calotte d'étanchéité élastomère (15). Ces moyens de verrouillage peuvent comprendre deux pattes (17) ou un disque cruciforme (20).

Title: Leached nanocrystalline materials, method for making them and uses in the energetic sector
Inventor: SCHULZ ROBERT
IPC: B22F1/054
Filed: 1998-01-21
Granted: 2007-03-27
Abstract: The invention concerns leached nanocrystalline materials having a large specific surface area particularly useful for storing hydrogen or for making electrodes for catalysis or electrocatalysis, such as those used in fuel cells. These materials can be made by preparing a nanocrystalline material consisting of a metastable composite or alloy of at least two distinct chemical elements. To be nanocrystalline, the material should have a crystalline structure with crystals less than 100 nn. in size. The prepared nanocrystalline material is then subjected to a leaching so as to eliminate partly or totally at least one of the elements of the composite or alloy. This leaching gives the resulting material a porous structure and, hence the required large specific surface area.

Inventor: FANINI OTTO N
IPC: G01V3/28
Filed: 1999-07-06
Granted: 2006-09-19
Abstract: A method for generating an improved estimate of horizontal conductivity, dip angle, azimuth and anisotropy parameter of an earth formation penetrated by a wellbore from dual-frequency transverse electromagnetic induction measurements, comprising generating an initial estimate of the horizontal conductivity, dip angle, azimuth and anisotropy parameter from the dual-frequency transverse induction measurements made at each one of a plurality of base frequencies. The initial estimates from each of the plurality of base frequencies are input into a primary trained neural network, and the improved estimate is calculated by the trained neural network. The network is trained by generating models of earth formations each having a known value of horizontal conductivity, anisotropy parameter, dip angle and azimuth. Voltages which would be measured by the transverse electromagnetic induction instrument in response to each model are synthesized. Initial estimates from the synthesized voltages are calculated and the initial estimates and known values from each of the models are input to the neural network to cause it to learn a relationship between the initial estimates and the known values.
