Patent CA-2296511-A1 (CA)
Inventor: HARE ROBERT V
IPC: A61K6/90
Filed: 1999-05-25
Abstract: Cette invention porte sur une composition binaire améliorée de très haute viscosité Putty à base de polyorganosiloxane polymérisable. Cette composition qui convient à la prise d'empreintes dentaires, se distingue par une résistance accrue à la déchirure, sa maniabilité et sa mouillabilité. La résistante accrue à la déchirure résulte de l'inclusion d'un polysiloxane quadri-fonctionnel d'une teneur en vinyle comprise entre 0,16 et 0,24 m-moles/g. Le temps d'emploi est prolongé grâce à l'inclusion de quantités suffisantes d'un retardateur de prise qui retarde le départ de la polymérisation du vinyle. La maniabilité est améliorée grâce à l'addition d'un polydiméthylsiloxane de très haute viscosité se terminant par des vinyles linéaires, ce qui réduit la tendance à poisser et qui améliore la stabilité au stockage. On a accru la mouillabilité en incluant un tensioactif procurant un angle de contact superficiel avec l'eau de moins de 50· à trois minutes. Le tensioactif choisi présente un rapport hydrophile-lipophile de 8-11, ce qui fait que l'angle de contact mouillant est atteint en moins de deux minutes, et qu'il reste mouillant pendant tout le temps d'emploi nécessaire à la prise d'empreinte, ce qui vient améliorer sensiblement le procédé de prise d'empreinte.
Patent CA-2299922-A1 (CA)
Inventor: BRUMBOIU AUREL
IPC: G01N33/28
Filed: 2000-03-03
Abstract: A method for determining a correction factor for use in analysing the concentration of a gas in a liquid is described. The correction factor is determined by measuring the output concentration of the gas in the liquid as the gases saturation limit in that liquid. The method is useful with gas permeable membrane technology to measure the concentration of the gas in the liquid. The method includes applying a correction factor to give the true concentration of gas in the liquid taking into account both that gas in solution in the liquid and that amount of gas present as entrained bubbles in the liquid.

Title: A simulated fireplace made from a compressible material
Inventor: HESS KRISTOFFER
IPC: B05D5/06
Filed: 2000-03-24
Abstract: The present invention is directed to a simulated fireplace formed, at least partially, from a compressible material, and to a method of forming a simulated fireplace from a compressible material that has a surface that simulates surfaces found in real fireplaces. In particular, this invention forms a simulated fireplace using a compressible material, such as wood, wood composites, or plastics. A pattern is pressed into a surface of the compressible material forming a sculptured surface. The surface is also coated. In one embodiment of the invention the surface is coated with a solvent based coating, for example, a sealer, a primer, and a finish that can include colour and/or gloss. In another embodiment of the invention the surface is coated with a powder coating, such as a law temperature epoxy. In yet a further alternative the surface is coated with a polymer film. By pressing a pattern into the material surface and canting the surface with an appropriate coating, a variety of surfaces found in real fireplaces can be simulated, for example, cast-metal or masonry surfaces.

Patent CA-2311367-A1 (CA)
Inventor: MURRAY JAMES
IPC: H04M15/00
Filed: 1998-11-20
Abstract: The conventional one-to-one relationship between a mobile station (14) and its associated service profile (38) is broken to allow for plural service profiles to be selectively activated for use in connection with a single mobile station. These plural service profiles are stored in the home location register HLR (20) of the cellular network (10). A separate billing identification (44) is maintained for each service profile in order to allow for segregated billing of service charges incurred with respect to use of the mobile station. Selection of a certain one of the plural service profiles to be active for a mobile station is made through, for example, a default choice, a user selected choice, a feature code selected choice, or a schedule driven selected choice. The active one of the plural service profiles is down-loaded from the home location register, and applied in connection with both in-coming and out-going calls.

Abstract: A resonant optical modulator includes an electro-optical substrate, an optical waveguide formed in the substrate and having a variable index of refraction, and an active modulator electrode formed on the substrate in relation to the waveguide to effect electro-optical variation of the index of refraction upon application to the electrode of a modulating signal. An interface port formed on the substrate provides the modulating signal to the electrode from a signal source and has an impedance. An electrical structure, formed on the substrate and coupled to the interface port and the electrode, makes an impedance of the optical modulator substantially equal to the impedance of the signal source. The electrical structure includes a delay line and a stub formed on the substrate.

Title: Burst-ultrafast laser machining method
Inventor: HERMAN PETER R
IPC: B23K26/062
Filed: 2001-01-25
Abstract: A method of laser processing or laser modification of materials. The combination of ultrafast laser pulses and high-repetition rate ( > 100 kHz) bursts (or continuous operation) defines a new and unexpected regime for material processing. The high repetition rate controls thermal and/or other relaxation processes evolving between each ultrafast laser pulse that 'prepares' the sample surface or bulk to alter the interaction with subsequent ultrafast laser pulses and thereby improve or optimize the process, or enable a new process, that are not available at lower repetition rate. The addition of this laser-controlled thermal component, and/or the general control of relaxation processes , overcomes several current limitations of ultrafast laser processing at lower repetition rates ( < 100 kHz), providing means to further harness the many attributes of ultrafast lasers for general material processing and material modification applications.

Inventor: SEREDA ANATOLY PAVLOVICH
IPC: C01B31/06
Filed: 1998-07-08
Abstract: The present invention relates to a principle for the heterogeneous liquid-phase crystallisation of diamond, wherein said crystallisation is carried out on the heterogeneous surface of a catalyst. This surface is characterised in that, during the high-temperature dehydrogenation process of heavy hydrocarbons containing bitumen-tar and asphaltenes, the catalyst performs a chemisorption of hydrogen under an atomic form. The catalyst surface submitted to the chemisorption exhibits a characteristic which is essential for the crystallisation of diamond in that only the growth of crystalline carbon-diamond is possible. This invention also relates to a method for implementing this principle with a yield in excess of 3,000 carats of diamond crystals having various fractions of between 100 and 1000 microns. During the experiments, the largest diamond crystal obtained had dimensions of 3.5 x 3.5 mm, while the production of diamond crystals with maximal dimensions was not contemplated as a goal.
