Patent CA-2492697-A1 (CA)
Inventor: CORNWELL JAMES P
IPC: F16K15/02
Filed: 2003-07-10
Abstract: A check valve (20) with a body (22) and a hole (30) extending from an inlet (24) to an outlet (26). A piston assembly (52), mounted in the body (22), includes a piston (54), a check valve seal (60) and a piston spring (55). The piston spring (55) biases the piston (54) to a first location preventing air from flowing from the inlet end (24) toward the outlet end (26). The check valve seal (60) is positioned to seal against a check valve seat (37).  Movement of the piston (54) removes the check valve seal (60) from the check valve seat (37), allowing air to flow from the inlet end (24) toward the outlet end (26). A tapered portion (64) of the hole (30) permits usage with systems having different volume output levels. A dampener (31) reduces fluctuations of the piston (54) caused by cyclical fluctuations in fluids controlled.

Abstract: A stable heli-borne vector platform capable of accepting a range of different sensors or instruments, particularly, but not exclusively, for the mapping and exploration of mountainous regions is described. The platform enables the arrangement of the sensors in three orthogonal directions, thus allowing the restitution of the resultant vector. The geographical referencing is provided by the use of a differential GPS receiver, whose antenna is installed on the main body of the platform. This platform distinguishes itself from its predecessors through the use of a lateral pulling axis, the use of a heavy weight placed underneath the main body, and by a perfectly symmetrical geometry in the direction of pull, thus ensuring perfect in-flight balance and stability.

Title: Systeme de propulsion universel
Inventor: COELLO CEDENO ROBERTO HUGO
IPC: F03G3/00
Filed: 2005-09-09
Abstract: Dans tous les systèmes de propulsion connus, la force d'action est appliquée à une masse qui va à l'extérieur ou qui à est l'extérieur. Dans l'invention Système de Propulsion Universel toutes les forces impliquées restent à l'intérieur. Nous avons toujours beso in d'une masse où appliquer une force d'action et avoir une force de réaction. Dans cette invention les masses sont en groupes de paires séparées, elles font des double tours, les masses sont accouplées à des axes, les poids principaux des masses sont concentrés à l'extérieur dans un angle inférieur a 180.degree. . Les masses tournent autour des axes, avec un radio plus petit que le radio de f axe central, les paires des masses sont séparées dans un angle de 180.degree., toutes les masses tournent à la fois autour d'un axe central, avec un radio plus grand, quand une masse e st entre les deux axes, l'axe d'engrenage central et l'axe où la masse est accouplée, le mouvement de la masse va être en direction opposée au sens de rotation de la partie rotative qui tourne au tour de l'axe central. Quand une masse sera trouvée à l'extérieur, la direction du mouveme nt va coïncider avec la direction de la rotation de la partie rotative qui tourne avec Taxe central. Quand les masses se trouvent plus proches du centre de rotation de l'axe central, l'accélération commence et finit à 180.degree. de différence dans le point plus éloigné de l'axe central, du point plus éloigné au point plus proche de l'axe central il y a une décélération. Il y a une accélération dans un angle de 180.degree., qui se traduit comme une force de réaction et une décélérati on dans les 180.degree., qui se traduit comme une force action. La force de réaction et la force d'action so nt dans la même direction et produisent une force résultante équivalente à l'addition des forces. Le mécanisme qui permet l'accélération et décélération des masses est un mécanisme compos é des roues de engrenages, toutes les roues d'engrenages ont le même numéro de dents et le même diamètre, une roue d'engrenage est fixée à un axe central, cette roue d'engrenage ne tourne pas. Les autres roues d'engrenages sont attachées à des axes autour de la roue d'engrenage centrale, les roues d'engrenages font des rotations autour de la roue centrale et la mue d'engrenage centrale, qui ne tourne pas, les oblige à tourner sur elles-mêmes. Comme les masses sont accouplées aux axes des quatre roues d'engrenage, les masses vont tourner synchronisées par le mécanisme, à chaque tour les masses accélèrent dans le même angle de 180.degree. et décelèrent dans les autres 180.degree. qui complètent le tour. Une force motrice doit être accouplée à la partie tournante.

Title: Cubic logic toy
Inventor: VERDES PANAYOTIS
IPC: A63F9/08
Filed: 2004-05-13
Abstract: This is an invention that concerns the construction of three-dimensional logic toys, which have the shape of a normal solid, substantially cubic in shape, and N number of layers in each direction of the three-dimensional rectangular Cartesian coordinate system, said layers consisting of smaller separate pieces. Their sides that form part of the solid~s external surface are substantially cubic. The said pieces can rotate in layers around the three-dimensional axes of the coordinates; their visible rectangular surfaces can be colored or they can bare shapes, letters or numbers. The construction is based on the configuration of the internal surfaces of the separate pieces using planar, spherical and mainly right conical surfaces, coaxial to the semi-axis of the coordinates, the number of which is .kappa. per semi-axis. The advantage of this construction is that by the use of these .kappa. conical surfaces per semi-axis, two solids arise each time; the first has an even (N=2.kappa.) number of layers per direction visible to the user, whereas the second has the next odd (N=2.kappa.+1) number of visible layers per direction.  As a result, by using a unified method and way of construction, for the values of .kappa. from 1 to 5, we can produce in total eleven logic toys whose shape is a normal geometric solid, substantially cubic in shape. These solids are the Cubic Logic Toys No N, where N can take values from N=2 to N=11. The invention became possible after we have solved the problem of connecting the corner piece with the interior of the cube, so that it can be self -contained, can rotate unobstructed around the axes of the three-dimensional rectangular Cartesian coordinate system and, at the same time, can be protected from being dismantled. This invention is unified and its advantage is that, with a new different internal configuration, we can construct - apart from the already known cubes 2x2x2, 3x3x3, 4x4x4, 5x5x5 which have already been constructed in many different ways and by different people - the next cubes from N=6 up to N=11. Finally, the most important advantage is that it eliminates the operational disadvantages that the already existing cubes have, except for the Rubik cube, i.e. 3x3x3.

Abstract: The present invention is a high-throughput, ultraviolet (UV) assisted metalorganic chemical vapor deposition (MOCVD) system for the manufacture of HTS-coated tapes. The UV-assisted MOCVD system of the present invention includes a UV source that irradiates the deposition zone and improves the thin film growth rate. The MOCVD system further enhances the excitation of the precursor vapors and utilizes an atmosphere of monatomic oxygen (O) rather than the more conventional diatomic oxygen (O2) in order to optimize reaction kinetics and thereby increase the thin film growth rate. In an alternate embodiment, a microwave plasma injector is substituted for the UV source.
