Abstract: Cette invention se rapporte à un commutateur à pédale, qui comprend un logement définissant une cavité, laquelle est délimitée par une paroi supérieure, par des parois latérales et par des parois joignant les parois latérales. Deux éléments généralement profilés en U comportent des pédales et des bras actuateurs, lesquels sont tourillonnés dans les parois latérales de façon à faire saillie par rapport au logement, pour qu'ils soient accessibles à une pression avec le pied, qui les met en rotation. Des moyens de sollicitation élastiques agissent sur les bras actuateurs et poussent les pédales dans une position supérieure. Au moins un commutateur comportant un élément actuateur est fixé dans ledit logement. Lorsqu'on abaisse les pédales par une pression du pied, on fait tourner les bras actuateurs et on provoque l'actionnement de l'élément actuateur du commutateur.

Filed: 1998-11-19
Abstract: L'invention concerne un réactif pour le traitement ou l'imagerie des tumeurs cancéreuses in vivo, qui comprend un hydrate de carbone auquel est lié un atome paramagnétique. Cet hydrate de carbone est capable de liaison ou de pénétration vis-à-vis des cellules cancéreuses. Lorsque le réactif considéré est utilisé en imagerie, le gadolinium constitue l'atome paramagnétique préféré, mais on choisit de préférence le fer à cet effet dans le cas d'une utilisation du réactif pour l'application d'énergie thermique à une tumeur. Le réactif peut être dans un vecteur, lequel peut comprendre des liposomes. Ce réactif peut être utilisé en combinaison avec d'autres matériaux diagnostiques ou thérapeutiques. Le glucoside de gadolinium représente un matériau préféré en l'occurrence.

Title: Rod locking mechanism for compression slack adjuster
Inventor: KANJO WAJIH
IPC: B61H15/00
Filed: 2000-07-14
Abstract: A locking assembly for preventing accidental let out of a slack adjuster is provided wherein the slack adjuster includes an elongated hollow housing member and an elongated rod member mounted for reciprocal movement within the hollow housing member. At least a portion of the rod member extends outwardly from a first end of the slack adjuster and is movable in a lateral direction with respect to a longitudinal centerline of the hollow housing member. A rod weldment washer is secured to the rod member at a predetermined location intermediate each end thereof. This rod weldment washer is positioned within the hollow housing member such that a side edge thereof is a predetermined distance from an inner surface of a sidewall of the hollow housing member during normal operation of the slack adjuster. A force applying means is disposed at the first end of the slack adjuster for applying a force to the rod member in a lateral direction with respect to the longitudinal centerline of the rod member thereby causing the rod member and the rod weldment washer to move in a lateral direction with respect to the longitudinal centerline of the hollow housing member to frictionally engage the side edge of the rod weldment washer with the inner surface of the hollow housing member. This frictional engagement prevents longitudinal movement of the rod member within the hollow housing member and consequently prevents the accidental let out of the slack adjuster.

Patent CA-2320532-A1 (CA)
Inventor: MANZOLI NICHOLAS J
IPC: A61C5/00
Filed: 2000-09-22
Abstract: In general, the invention consists of indicator means for indicating the usage of an endodontic instrument by providing a visual indication of the number of sterilizations of the instrument. The indicator means includes a modified "stop" or "washer" which is used with each endodontic instrument. The "stop" includes a dye compatible base which is impregnated with a diffusible dye Composition. The base is made of a dye compatible material which enables the diffusible dye to migrate or diffuse as a result of a specific number of sterilizations at a specific temperature from an interior portion in the base where the dye is not visible to an exterior position where the dye is visible. Since the "stop" is also sterilized along with the instrument, the "stop" will change color after a specified number of sterilizations of the instrument has occurred. Since each endodontic instrument is sterilized after each use, the change in color of the "stop" will also provide a visual indicator of the number of times the endodontic instrument has been used. More specifically, the base is of pure polymer composition, essentially free of additives, and the dye is any of various known polymer compatible dyes capable of diffusing within a dye compatible polymer. An alternate configuration of the invention utilizes materials of different melting points instead of diffusible dyes in the wells on the instrument handles.

Title: Piezo-electric, quantum effect motor
Inventor: CASCIATO BRUNO
IPC: H01L41/09
Filed: 2000-09-21
Abstract: In the past ten years, there have been many scientific and mathematical papers written on the properties of space-time and linear dimensions of sub-atomic scales in the order of, 10-33cm. This domain is currently known as the "zero point energy"  plenum, and theory suggests that our familiar Cartesian coordinates, x,y,z, do not exist at this Planck length. The classic Lorentz equation describes our familiar world as;   x2 + y2 + z2 - ct2 = 0 in the van der Waals domain.    At the Planck length of 10-33 cm, this equation approaches its' inversion as;   ct2 - x2 - y2 - z2 = 0 in the ZPE domain.   In this domain, any wave would behave as a particle with finite mass, inertia, and perhaps electric charge. A pressure wave, or phonon, travelling through the van der Waals domain in conventional solids, liquids or gases, loses its' energy as it propogates through the medium, dissipating its' energy as a function of time and distance. This energy is consistent with the generation of heat and obeys the 2nd law of thermodynamics. If a propogating phonon could approach the ZPE boundary at the forementioned value, its' energy would remain constant and would now become a soliton wave at this boundary. This soliton wave will behave as a particle with finite mass at the ZPE  boundary, with no loss of energy as would be expected with a conventional particle interracting with its' medium of propogation. The transition between the van der Waals domain, and the ZPE domain is assumed to be non-linear and not clearly defined.
