Title: Method and apparatus for determining bone density
Inventor: DIMAROGONAS ANDREW W
IPC: G01N29/00
Filed: 1994-03-01
Abstract: The integrity (density) of discrete pieces of hard tissue (bones) in a patient may be determined by either one of two methods. In a first method, an impulse of energy is introduced into the bone, such as by striking the patient's bone, and the induced vibration is sensed and analyzed in order to compute the damping factor thereof, the damping factor being directly related to the density thereof.  With this method, a transducer (26) is coupled to the bone (24) and its output is amplified by an amplifier (28) before input to a computer (30) which determines the damping factor. In a second method, a continuous energy input is provided to the bone, such as by utilizing a frequency generator (36) coupled to a power amplifier (38) whose output drives a transducer (40) such as a speaker for inducing a continuous vibration in the bone. This continuous vibration is measured with a transducer (26), an amplifier (28), and a damping factor calculated with a computer (30) as in the first method.

Les parties de membrane présentent des bords opposés adjacents réunis au niveau de deux pattes espacées. Une pluralité de capteurs sont répartis sensiblement uniformément sur la membrane, chaque capteur occupant une surface prédéterminée. Des conducteurs sont montés sur la membrane de façon à s'étendre entre les capteurs et une position le long de la périphérie de la partie associée afin de permettre d'établir une connexion externe avec le dispositif de contrôle. Chacune des parties de membrane comprend en outre une paire de fentes s'étendant à partir d'une région médiane espacée du bord opposé respectif, vers l'extérieur et dans des directions divergentes le long de lignes passant à l'extérieur des zones prédéterminées de la membrane occupées par les capteurs. Les fentes délimitent une partie supérieure s'étendant généralement le long de la colonne vertébrale d'un cheval, et une partie latérale s'étendant vers le bas, le long du flanc du cheval, et s'éloignant de la colonne vertébrale. Lorsque la membrane est placée sur le dos d'un cheval de façon que les bords opposés s'étendent le long de la colonne vertébrale, elle épouse généralement la forme du dos du cheval, les parties supérieure et latérale étant séparées par l'étalement des fentes. La membrane peut également être étirable entre des capteurs individuels. Les pressions détectés par les capteurs sont introduites dans un ordinateur, qui génère un affichage de la répartition de la pression.

Patent CA-2189692-A1 (CA)
Title: Electronic device for converting electrical energy
Inventor: MEYNARD THIERRY
IPC: H02M7/48
Filed: 1996-03-06
Abstract: The converter has a succession of controlled commutators each having two switches, with two front and two back poles. These are cascade connected between a voltage and current source. Each commutation cell has an associated capacitor (C1,C2..Cn). The switches are controlled successively to two conducting states in a cyclically repeated period. If shifted a fraction of time period, the capacitors sustain the crossing voltages, equal to source voltage divided by cell numbers and cell ranking. Mean capacitor voltages are measured (VMO1,VMO2...VMOn) for each cell and compared (VE1,VE2...VEn) with their nominal charge. Thus complementary controls (MCC1, MCC2...MCCn) modify the converter control signals to reduce the difference between actual and nominal voltages, by changing the first conducting time of the associated cell.

Inventor: DORRICOTT JONATHAN
IPC: B21B1/34
Filed: 1996-06-06
Abstract: An optimizing method for improving the efficiency of production is provided for a steel rolling mill using a Steckel mill to roll steel slab to end-product thickness, and associated downstream equipment of limited capacity to generate strip and/or plate end-product. The optimizing method allows for continuous processing of steel slab of a mass within the capacity limits of the Steckel mill and equipment upstream of the Steckel mill, but in excess of the capacity of the associated downstream equipment, by first rolling the slab in the Steckel mill to intermediate coilable thickness, and then severing the intermediate steel product to produce two derivative segments, one of a target mass within the limit of capacity of the toiler furnaces and downstream equipment, and another, typically smaller, residual segment. The residual segment is disposed of, optionally first milled to end-product thickness in the Steckel mill, and transferred to conventional downstream equipment. In the meantime, the target segment is held within a toiler furnace. The target segment is subsequently milled and finished to end-product thickness. The method improves the efficiency of production in a steel rolling mill.
Patent CA-2198712-A1 (CA)
Inventor: MACKENZIE INNES K
IPC: G01B15/02
Filed: 1995-08-30
Abstract: The present invention provides a method and apparatus for non destructive, in situ measuring thicknesses of layers on substrates. The method and device uses a probe of a radioactive source and a photodetector mounted behind the source for detection of backscattered photons. In one aspect the method is used to measure the thickness of paint deposited onto galvanized steel such as used in vehicles. A source containing radioactive 109Cd producing high energy photons of energy 23 and 25 keV is spaced from the painted surface so the photons impinge on the painted substrate. The intensity of photons backscattered by Compton scattering in the paint layer is proportional to the mass density of the paint to give a direct measurement of the paint thickness. The photons penetrating through to the substrate are absorbed within the substrate. In another aspect the method is utilized for measuring ice thickness on airfoils.  The probe is mounted on the interior of the airfoil and the source is 241Am producing 60 keV photons which penetrate through the airfoil substrate and are backscattered within the ice layer and back through the airfoil substrate to the detector. The shape and density of the source holder in addition to the geometrical arrangement of the source and detector with respect to the airfoil substrate are used to block photons backscattered in the airfoil substrate thereby favoring scattering in the ice layer over that in the aluminum.

Title: High temperature, high pressure retrievable packer
Inventor: GANO JOHN C
IPC: E21B33/129
Filed: 1997-03-05
Abstract: In a retrievable packer adapted for service under high temperature and high pressure operating conditions, improved retention of the packer in the wellbore is achieved by use of an inventive slip/wedge system, wherein the cones on the wedges are spaced a progressively slightly greater distance apart from their corresponding slip cones, from the centermost slip cone to the outermost slip cone. This forces the center of the slip to be loaded first. As greater forces are exerted on the wedges from end to end, the wedge will deform slightly and the next cone of the wedge will make contact with its matching portion of slip.      Thereby, as the wedges are loaded higher and higher, more wedge cones come into bearing contact with the slip. Further, a barrel slip is used, to provide a uniform circumferential distribution of forces. This design effectively allows initial setting of the packer with very little slip tooth contact area. This permits the slip to quickly get a good grip into the casing wall. Subsequent higher loading brings more and more slip teeth to bear and prevents overstressing the casing.
