Patent CA-2321701-A1 (CA)
Title: Connection for connecting a measuring device to a gas unit
Inventor: LANGEVELD JACOBUS FRANSISCUS
IPC: F16L55/07
Filed: 1999-03-10
Abstract: The invention relates to a connection for connecting a measuring device (6) to a gas pipe, comprising: a connecting element (1) for arranging in the gas pipe which divides the gas pipe into a first and a second piece (2, 3); a connecting plug (4) which can be coupled to the connecting element and which is connected to the measuring device by means of a measuring line (5), wherein the connecting element comprises a valve which is actuable by the connecting plug and which normally mutually connects the first and the second piece of the gas pipe and which, when the connecting plug is coupled to the connecting element, connects the first piece of the gas pipe to the measuring line and closes the second piece of the gas pipe. As a result of these measures the valve is operated by the connecting plug, so that opening and closing of taps is no longer necessary. The operation of such a connection is therefor greatly simplified. A perhaps even more important advantage lies in the fact that safety is ensured, since when the connecting plug is removed the measuring line is automatically closed.

Filed: 2001-02-28
Abstract: Un système et une méthode de gestion de cache de série d'objets ayant des spécifications de durée de vie explicites, selon lesquels un gestionnaire temporel effectue la maintenance et les mises à jour d'un ou plusieurs ensembles d'objets stockés dans la mémoire cache. Un ensemble d'objets en antémémoire comprend des objets ayant des heures de début et/ou de fin qui représentent, respectivement, les heures où ces objets deviennent valides et expirent. Une heure de mise à jour est déterminée pour un ensemble donné d'objets stockés en mémoire cache en fonction, d'une part, des heures de début et des heures de fin des objets comprenant l'ensemble d'objets stockés en mémoire cache. Quand une requête pour récupérer un objet de l'ensemble d'objets stockés en mémoire cache en question (ou la totalité de l'ensemble d'objets stockés en mémoire cache) est reçue, il faut déterminer si l'ensemble d'objets stockés en mémoire cache est valide au moment de la requête en fonction de l'heure de mise à jour. Si l'ensemble d'objets stockés en mémoire cache n'est pas valide parce que, par exemple, l'heure de mise à jour a expiré, l'ensemble d'objets stockés en mémoire cache est mis à jour (et tous les autres ensembles d'objets se trouvant en mémoire cache, si nécessaire) en supprimant et/ou en ajoutant des objets à l'ensemble d'objets stockés en mémoire cache dont les heures de début et les heures de fin répondent à des critères d'heure prédéfinis d'inclusion dans l'ensemble d'objets stockés en mémoire cache.

Title: Wheelchair suspension system
Inventor: PETERSON CHRISTOPHER J
IPC: A61G5/10
Filed: 1999-08-26
Abstract: A wheelchair suspension system comprises a suspension assembly disposed adjacent to each wheel of the wheelchair, and attached to and interconnecting the axle (13) of the wheels to the wheelchair frame.  Each of the suspension assemblies includes a front bracket (16) and a rear bracket (17), wherein the front bracket (16) is attached to the wheelchair frame and the rear bracket (17) is attached to the axle (13). Top and bottom generally L-shaped arms (35) each are privotally attached to each of the brackets in a diametrically opposed fashion, and an elastomeric spring (19) is disposed between and interconnects the arms. When one or more of the wheels encounters a bump in a travel surface of the wheelchair, the arms move closer together to compress the spring. Conversely, when one or more of the wheels encounters a depression, the arms move farther apart to place tension on the spring. The pivoting parallel arrangement of arms and brackets enables displacement of the axle in a substantially vertical, relatively large distance when one or more of the wheels encounter an irregularity in the wheelchair travel surface, which in turn maintains stability and steering control of the wheelchair by keeping the wheels in contact with the travel surface.
Patent CA-2342297-A1 (CA)
Title: Molten metal inclusion sensor probes
Inventor: LI MEI
IPC: G01N15/00
Filed: 2001-03-26
Abstract: The invention provides molten metal inclusion sensor probes having a sensing passage through which the molten metal passes, while a direct curren t path is established through the passage between two electrodes. The passage of an inclusion through a central sensing zone within the passage changes the electric resistance in the current path, resulting in a detectable pulse indicating its size, and enabling the number of particles in a sample to be counted. Previously the passage has been cylindrical, with or without a conical entrance to facilitate smooth flow, or of randomly smoothed profile produced by heating the materia l at the passage mouth until it melts and flows. The flowing metal produces a sel f- induced magnetic field and electromagnetic force that results in a "conditioning" flow when the current is above a threshold value. High levels of background noise making pulse detection difficult, and it is proposed to improve operation by machining the passage to decrease smoothly in flow cross section from its entrance to the sensing zone, preferably with a parabolic or elliptical profile. Preferably the exit has the same profile. Further improvement can be obtaine d by machining the wall surface to a smoothness of better than 1.016 micrometers (40 microinches). Such precise, smooth-walled passages facilitate the design of systems as to the optimum testing and conditioning currents required.</SDOAB >

Abstract: The application describes a novel mechanism of action, that is modulation of  the specific effectiveness of I-kappa-kinases or cyclic nucleotide phosphodiesterases (PDEs) which have the ability to cleave cGMP or cAMP. The  preferred mode of action is dislocation, disruption of targeting or interference with redistribution of specific isoforms or splice variants of PDE4, PDE5, or I-kappa-kinases from their anchoring sites within cells, thereby modulating their specific effectiveness, not their enzymatic capacit y. The chemical entities may be useful in preventing or treating in an animal, preferably a human, in need thereof an adverse condition which may be reduce d or abolished by modulating the specific effectiveness of PDE4, PDE5, or I- kappa-kinases.
Patent CA-2347319-A1 (CA)
Title: Treadmill cushion
Inventor: WAITE PATRICK J
IPC: A63B23/04
Filed: 2001-05-11
Abstract: A treadmill (10) includes a frame (12) on which are rotatably mounted first and second transverse roller assemblies (14, 16). An endless belt (18) is trained around the roller assemblies. A deck (20) is supported between the upper run of the belt and the frame by a plurality of rectilinear-shaped elastic cushions 100 that are reversibly deformable under the load imposed on a deck by the footplant of the treadmill user. The cushions 100 are not of uniform cross-section; rather, one or both of the ends of the cushions are relieved so as to present a nominally reduced cross-sectional area against the frame and/or deck. As the cushion is compressed from the load imposed on the deck, the cross-sectional area of the cushion providing resistance to further deformation/deflection of the cushion increases thereby increasing the resistance or stiffness of the cushion to further deformation and thus further travel of the treadmill deck (20) towards the frame (12).

Title: Data sale immediate settling method and prepaid card
Inventor: SHICHI SHUJI
IPC: G06Q30/06
Filed: 2001-06-13
Abstract: To enable settlement with a real-time nature and a high security that needs no certification data directly connected to an individual.      Actions on a purchaser's end include an action of inputting the purchaser's ID, the n-th action of inputting the n-th password used at the n-th time to a terminal, an action of inputting the (n+1)-th password used at the (n+1)-th time to the terminal, and an action of inputting contents to the terminal. Actions on a seller's end include an action of distributing the contents to the purchaser, and an action of subtracting a price corresponding to the contents from the balance in a database. A serial number being peculiar to the seller and being unchangeable is collated with a password being changeable, and the password can be changed every time a purchase is implemented so that a security is significantly raised. Unchanging the password under a state where it can be changed is substantially equal to changing for a third party so that it is not necessary to change the password every time a purchase is implemented. The prepaid card can safely be distributed to an unspecified number of people.

Patent CA-2365315-A1 (CA)
Inventor: SMITH RONALD R
IPC: G06F21/00
Filed: 2001-12-17
Abstract: A developer (102) develops a software application (204) which needs to~ be tested or debugged, or both. To eliminate the deed to either intentionally compromise the security environment of the target portable device, or having to request a certificate for each version of the software under development, the developer obtains a development certificate (208). The development certificate includes a device identifier unique to the particular portable device on which the software is to be tested, and some development parameter. The target device uses these two pieces of data to determine if the software is valid, and executable. If either of these pieces of data are not valid, the security mechanism of the target device will disable the software, or otherwise refuse to permit it to execute. The developer signs the software with the~ development certificate, and then loads the signed software onto the target device, which then authenticates the developer's signature and development certificate.
