Inventor: BERARD JEREMY
IPC: B64D39/00
Filed: 2004-10-05
Abstract: The process involves predicting a fuel quantity remaining aboard an aircraft at a flight point, by considering current state of the aircraft and current flight conditions. Another fuel quantity permitting the aircraft to fly from the point to another flight point of flight plan is estimated. A third fuel quantity to be transferred at the former point is determined from the two quantities and is displayed to aircraft pilot. Independent claims are also included for the following: (1) a device for optimization of fuel quantity transferred on an aircraft at the time of transfer of fuel between the aircraft and an auxiliary aircraft during flight; and (2) an aircraft.

Abstract: A process for making filamentous pyrophoric zinc comprising (a) electrolyzing a suitable zincate anion-containing alkaline solution in an electrolytic cell having a cathode and an anode, in the absence of an inhibitory amount of an inhibitor to inhibit said deposition of filamentous zinc, to effect deposition of filamentous zinc on said cathode;  (b) washing the filamentous zinc with a suitable solvent to remove the alkaline solution from the filamentous zinc to produce washed filamentous zinc; (c) removing the filamentous zinc from the cathode, either before or after the washing step (b); (d) drying the washed filamentous zinc wither before or after the removal from the cathode, in an essentially oxygen-free atmosphere to produce filamentous, pyrophoric zinc; (e) collecting the filamentous, pyrophoric zinc under an essentially oxygen-free atmosphere. The process provides for efficacious production of pyrophoric zinc suitable for use as a catalyst and a decoy against heat-seeking missiles.

Title: Outil a aleser coulissant a reglage fin
Inventor: CARDEMON RICHARD A
IPC: B23B3/00
Filed: 2003-04-25
Abstract: La présente invention concerne des procédés et un appareil permettant de régler avec précision la position d'un outil de coupe. Dans un mode de réalisation, l'invention concerne un outil à aléser comprenant un organe de couplage entraîné par une machine à aléser commandée par ordinateur, un outil de coupe couplé coulissant à l'organe de couplage, et un organe de réglage coulissant. Selon l'invention, une force de frottement résiste au mouvement coulissant de l'outil de coupe. La force de frottement est suffisante pour retenir la position de l'outil de coupe au cours des opérations d'usinage, mais elle est néanmoins insuffisante pour résister à une force de réglage appliquée par l'organe de réglage. Un mouvement coulissant de l'organe de réglage, que l'on produit en tirant ou en poussant ce dernier, entraîne un mouvement de l'outil de coupe. Dans un mode de réalisation, l'outil de coupe et l'organe de réglage peuvent coulisser dans des directions différentes. Dans un autre mode de réalisation, l'outil à aléser est apte, et configuré à cet effet, à transformer une première quantité, supérieure, de mouvement effectué par l'organe de réglage en une seconde quantité, inférieure, de mouvement effectué par l'outil de coupe.

IPC: F03B13/22
Filed: 2005-03-10
Abstract: The subject of this invention is an ocean wave air compressor that produces variable flows, by using the perpetual, clean, abundant and renewable energy of the sea waves. This compressor uses the force of the waves and the hydrostatic pressure of water in order to admit and compress air in an adjustable compression chamber where any waves' height is useful. The said compressor can be mounted in addition on pylons in the middle of seawater, where levelling means are used to lower or higher it during high and low tides. Air is compressed when the wave hits the compressor and water is admitted inside the compression chamber, and atmospheric air is admitted for the next cycle when the water recedes out of the compressor. The resulting compressed air is collected in a pressure tank to be used later to run a power plant such as that described in CA patent no 2328580.
