Patent CA-2211604-A1 (CA)
Inventor: KURIWAKI MASASHI
IPC: A61B8/08
Filed: 1996-11-28
Abstract: An apparatus for diagnosing osteoporosis which repeatedly radiates ultrasonic impulses (Ai) to a cortical bone (Mb) of a subject and receives echos (Ae) from the bone (Mb). The reception signal is converted to a digital echo signal by an A/D converter (8), and an echo level is detected by a CPU (11). The CPU  (11) extracts a maximum echo level from among the echo levels detected during the measurement period and calculates an acoustic impedance (Zb) of the cortical bone on the basis of the maximum echo level so extracted. The bone density of the subject is calculated from the calculated acoustic impedance (Zb) of the cortical bone by using a predetermined recurrent formula. The acoustic impedance of the bone is given by the square root of [elastic modulus x density] of a bone, and the elastic modulus of the bone increases (or decreases) with the increase (or decrease) of the bone density. Therefore, the elastic modulus of the bone and the bone density synergistically contribute to the acoustic impedance. For this reason, the acoustic impedance (Zb) of the bone is a good guide for judging the bone density.

Title: Method for purifying exhaust from wood manufacturing processes
Inventor: GRIBBON SEAN T
IPC: B01J23/16
Filed: 1996-02-12
Abstract: A method for the abatement of contaminant-laden process emissions produced by various wood manufacturing processes comprises the step of flowing the emissions through an oxidation catalyst (114, 116, or 118) located in a regenerative catalytic oxidizer (100) to remove volatile organic compounds (VOC's), methanol, formaldehyde, resins, binders, and hazardous air pollutants (HAP's) at lower peak temperatures than the temperatures encountered in regenerative thermal oxidizers. The oxidation catalyst allows the overall abatement process to operate at lower peak combustion temperatures. By reducing the peak combustion temperatures during the abatement of emissions, the present invention precludes potassium and/or sodium in the emissions from reacting with silica in the heat recovery media and ceramic fiber insulation of the regenerative thermal oxidizer. This reaction has heretofore destroyed the desired properties of the wood product and compromised the quality of te product.

IPC: E03D9/08
Filed: 1996-03-14
Abstract: The bidet is installed as an addition to a conventional toilet bowl (1) having a hinged seat and lid. A nozzle arm (5) is pivotable from an at-rest position, where the nozzle (6) is tucked away unobtrusively under the toilet seat near the rim of the toilet bowl (1), to an operative spray position in which the nozzle (6) is positioned centrally, to direct a gentle spray of water upwards at the underbody premises of a person sitting on the toilet bowl. Rotation of the lever arm (4) causes a cam (30) to push a spring-loaded plunger (46) open, to produce a flow of water from a supply line, to the nozzle (6). When the toilet seat is raised, a spring (18) raises the bidet assembly along with the seat, not only keeping it out of the way for male urination, but also facilitating cleaning of the toilet bowl.
Patent CA-2216915-A1 (CA)
Inventor: OKA MASAAKI
IPC: G06T15/00
Filed: 1997-02-06
Abstract: La présente invention concerne un procédé consistant à générer des données de dessin grâce à un prétraitement s'effectuant au niveau d'un préprocesseur (32) à partir de commandes de dessin conçues pour dessiner un modèle d'image défini par la combinaison de graphismes élémentaires. Un transfert s'effectue sur les données de texture dont le moteur de dessin (38) a besoin, d'une part pour générer les données d'image de graphismes élémentaires au moyen d'un traitement de mappage de texture à partir de ces données, et d'autre part pour les enregistrer dans le tampon de trame (18). Ce transfert s'effectue d'une zone texture du tampon de trame (18) vers une antémémoire de textures (33F) lors du prétraitement, la mise en oeuvre du préprocesseur (32) et du moteur de dessin (33) étant assurée par un processeur pipeline assurant. Le traitement de mappage de texture ainsi que le traitement de mappage MIP (Multum In Parvo = beaucoup dans peu de place) peuvent ainsi s'exécuter sans arrêt de la machine à dessiner, ce qui réduit d'autant le nombre des accès à la mémoire de textures ainsi que la durée de ces accès, et améliore donc la vitesse globale de dessin.

Patent CA-2223479-A1 (CA)
Title: Endovascular stent
Inventor: BORGHI ENZO
IPC: A61F2/958
Filed: 1996-06-07
Abstract: An endoluminal stent is formed in a modular construction to include an elongate spine and a plurality of generally tube-defining modules attached to the spine in a longitudinally sequenced array. Each module defines, in cooperation with the spine, a closed ring-like structure, with the modules being aligned in an array to define a generally cage-like tubular structure.  Each of the modules is radially expandable from a reduced diameter, low profile configuration, in which it is readily navigated through the body passages, to an expanded diameter engageable with the inner luminal surface of the body lumen. The stent, being of modular construction, can be built to individual specifications for a specific procedure in a specific patient.  Modules are formed from a wire shaped in a flat serpentine configuration that is then wrapped in a cylindrical configuration with its free ends connected to the spine. The modules are expandable, as by a balloon, from a low profile to an expanded configuration. During expansion, the modules can wipe against the inner surface of the lumen to smooth sharp points or edges. The spine of the stent defines a substantially greater mass than that of the individual modules such that the spine can be readily observed under X-ray or fluoroscopy. The modular construction enables a wide range of variation in the characteristics of the stent, including longitudinal flexibility, radial expansion characteristics, among others.

Title: Coupon inserter
Inventor: BOEHM MICHAEL
IPC: B65H35/10
Filed: 1997-12-09
Abstract: A coupon inserter assembly receives a continuous supply of coupons in the form of a web where the forwardmost coupon is attached to the following coupon along a weakened web portion.  The inserter assembly includes a pair of intermittently rotating feed rollers and a pair of continuously rotating delivery rollers.  An activation sensor is located at a dispensing location or a conveyor carrying receiving products for receiving coupons.  When the activation sensor senses a receiving product, a signal is sent to a clutch-brake to activate the feed rollers.  The feed rollers then feed the web into the delivery rollers.  When a deactivation sensor located beyond the delivery rollers senses the present of the forwardmost coupon, a signal is sent to the clutch-brake which stops the rotation of the feed rollers.  Because the delivery rollers continue to pull the forwardmost coupon, the two coupons separate along the weakened web portion.  The forwardmost coupon can then be delivered to the dispensing location for placement in or on the receiving product.

Title: Method of corona treating a hydrophobic sheet material
Inventor: MYERS DAVID LEWIS
IPC: D06M10/02
Filed: 1996-08-16
Abstract: A method of preventing localized arcing to ground during treatment of a sheet material in a corona discharge field generated by a corona discharge apparatus having at least two electrodes, which method involves passing the sheet material to be treated through the corona discharge field, in which the sheet material to be treated is electrically isolated from the electrodes. When the corona discharge apparatus has a bare metal electrode and a dielectric-covered electrode, the sheet material to be treated is passed through the corona discharge field as a layer of a multilayered composite having at least three layers, in which at least one of the layers is a nonconductive sheet material situated between the sheet material to be treated and the bare metal electrode. The method may be employed to treat a hydrophobic sheet material having a porosity, in which case the hydrophobic sheet material is passed through a corona discharge field generated by a corona discharge apparatus having a bare metal electrode and a dielectric covered electrode under conditions adapted to render the porous sheet wettable. The hydrophobic sheet material is a layer of a multilayered composite having at least three layers, in which at least one layer is a nonconductive sheet material situated between the sheet material to be treated and the bare metal electrode and one of the at least three layers is a nonconductive, nonporous sheet material.

Filed: 1998-02-20
Abstract: A heat transfer tube (10), and a method of manufacturing a heat transfer tube (10), having an external surface that is configured for enhanced heat transfer performance in both refrigerant evaporating and condensing applications. The tube is suitable for use in, for example, shell and tube type air conditioning condensers flooded evaporators, falling film evaporator, or a combination of flooded and falling film evaporator. The tube has at least one fin convolution (20) extending helically around its external surface (13). A pattern of notches (30) extends at an oblique angle (.alpha.) across the fin convolutions at intervals about the circumference of the tube. There is a split spike (22) having two distal tips (23) between each pair of adjacent notches. The fin convolution, notches and split spikes are formed in the tube by rolling the wall of the tube between a mandrel and, first, a gang of finning disks (63), second, a notching wheel (66) and third, a splitter wheel (67). Because of the interaction of the rotating and advancing tube and the notching wheel, during the manufacture of the tube, the maximum width (Wt) of the spike is greater than the width (Wr) of the proximal portion of the fin convolution.

Patent CA-2239343-A1 (CA)
Inventor: IWATA NAOTAKA
IPC: H03H11/28
Filed: 1998-06-02
Abstract: A matching circuit is formed by a series inductor, a parallel capacitor, a drain bias circuit, and a DC-blocking capacitor for the purpose of impedance matching. A capacitor having a capacitance that is dependent upon the bias voltage is used as the parallel capacitor. This can be, for example, a material such as a (BaxSr1x)TiO3 thin-film, which exhibits a capacitance having a bias voltage dependency.  Because this  thin-film capacitor exhibits polarization by an electrical field, its capacitance is the largest with a bias of O volts, and is reduced to approximately 50% as the bias voltage is increased. By using this capacitor in a matching circuit, it is possible to change the matching condition as the output power is increased, that is, as the voltage applied to the capacitor is increased. By considering both the condition which results in good transistor output and the condition which results in good distortion characteristics, it is possible to achieve a design in which the matching conditions are changed from a condition that emphasizes output power to a condition that emphasized low distortion, as the output power increases.
