Title: Apparatus and method for acoustic analysis of bone using optimized functions of spectral and temporal signal components
Inventor: WHITNEY HARWELL H
IPC: A61B10/00
Filed: 1996-03-13
Abstract: An apparatus and method determine externally in a vertebrate subject an index of porosity and non-connectivity of a bone. A preferred embodiment has first and second transducers and a mounting arrangement for mounting the transducers in spaced relationship with respect to the bone. A signal generator, in communication with the first transducer, causes the first transducer to produce acoustic signals, having energy distributed over a frequency range, that are propagated into the subject and received by the second transducer along a path that includes the bone. Finally, the embodiment has a signal processor, in communication with the second transducer, for providing a measurement that is a function of at least one of spectral or temporal components of the signal received by the second transducer. The transducers act like a point source and point receiver.

Filed: 1997-10-10
Abstract: A utility rack for carrying objects on a vehicle comprises an elongated carrier bar including a pair of outer carrier members each provided with a support foot adapted to rest onto the vehicle, and an elongated inner carrier member adapted to be secured at opposite ends thereof to the outer carrier members and thus form the utility rack. There are available inner carrier members of various lengths in order to meet vehicles having different spans or widths. The end  user will  thus  buy  a pair  of  standard  outer carrier members as well as an inner carrier member suitable for this user's particular vehicle.  A same inner carrier member can only be assembled to the two outer carrier members in a single position and the spacing between the support feet cannot be adjusted. When assembled, the inner and outer carrier members form a substantially continuous  support  surface as well as a substantially continuous channel extending substantially  the  length  of  the  carrier  bar  for receiving various accessories.

Title: Process for removal of polymer foams from nickel-coated substrates
Inventor: CUSHNIE KIRT KENNETH
IPC: H01M4/80
Filed: 1997-12-10
Abstract: The method of the invention produces nickel structures from nickel-coated polymer substrates. The nickel-coated polymer substrate has a nickel outer layer and initially has a temperature where the outer nickel layer lacks burst openings. Rapidly exposing the nickel-coated polymer substrate to a temperature of at least about 600°C thermally decomposes the polymer substrate and bursts holes through the outer nickel layer. The gases resulting from the thermally decomposed polymer substrate escape through the holes through the outer nickel layer to leave a nickel structure. Finally, annealing the nickel structure increases strength of the nickel structure to produce a ductile foam product.

Title: Method and apparatus for rolling strip
Inventor: SEIDEL JUERGEN
IPC: B21B37/28
Filed: 1997-12-22
Abstract: A method of rolling strip in a strip rolling train having at least two roll stands,, each roll stand having horizontally adjustable upper and lower work rolls, wherein the work rolls act alone as a two-high stand or each work roll is supported directly or through an intermediate roll by a back-up roll, or in a reversing stand in which at least two passes are rolled, wherein the strip is subjected in the roll stands to a constitutional change, and wherein adjusting elements act on the strip for imparting a profile and surface evenness to the strip. The method includes presupposing in at least one strip area an intended surface unevenness shape over a width of the strip, determining an actually achieved surface unevenness shape in the strip area and comparing the actually achieved surface unevenness shape to the presupposed unevenness shape, computing a difference between the unevenness shapes, and operating the adjusting elements such that the difference is minimized.

Patent CA-2230874-A1 (CA)
Title: Steering, tensing and driving a revolving casting belt using an exit-pulley drum for achieving all three functions
Inventor: WOOD J F BARRY
IPC: B22D11/06
Filed: 1998-02-27
Abstract: Steering, tensioning and driving a revolving metallic casting belt in continuous casting machines wherein the belt travels along a generally straight casting plane P. Two two-axis robotic mechanisms are positioned at opposite ends of an exit-pulley drum, each including a "floating" housing carrying a bearing rotatably supporting a journal at the respective drum end. A drive connected to one of the journals rotates the drum for revolving the belt. The robotic mechanisms adjustably position opposite ends of a rotating drum in X--X plane parallel with plane P for tensioning the belt and in Y--Y plane perpendicular to plane P for steering the revolving belt. These robotic mechanisms are controlled to operate in any of several modes: (1) "Walking-tilt" steering keeps the belt much closer to an exiting product than prior art, the belt being flatter and in better contact with the product for improving casting speed and quality. Mode (2) provides a "virtual squaring shaft" causing a drum to simulate being constrained by a rigid mechanical squaring shaft for synchronizing downstream movements of both drum ends for regularizing tension fully across a "cylindrical" casting belt. In modes (3),  (4) and (5) the rigidity of the virtual squaring shaft may be "softened," or re-zeroed or eliminated, to accommodate small "frustro-conical" errors in belt manufacture.          Moreover, even a small error in built-in length dimensions of a belt carriage may effectively be canceled by mode adjustments which effectively "twist" the virtual squaring shaft.

Patent CA-2248131-A1 (CA)
Inventor: MARWAH NIPUN
IPC: D21C5/02
Filed: 1996-03-08
Abstract: Cette invention concerne un procédé perfectionné de désencrage de vieux papiers qui contiennent des toners ou des encres d'impression au laser, électrostatiques ou d'un autre type sans impact dans le but de produire une pâte à papier de grande qualité (à forte blancheur et à teneur en impuretés faible ou nulle), et ce avec peu ou pas de perte fibreuse. Ledit procédé consiste à fixer les particules d'encre présentes dans la pâte de vieux papiers à une matière magnétique porteuse à l'aide d'un agent d'agglomération puis à extraire les particules d'encre fixées au moyen d'un processus de séparation magnétique. Ledit traitement magnétique est de préférence exécuté à température ambiante ou à une température supérieure à la température ambiante, à un PH neutre à alcalin et à une faible consistance de pâte. L'agglomération et l'addition de magnétite, suivies d'une exposition des vieux papiers retriturés à un champ magnétique, permettent une extraction presque complète des encres, ce qui n'est pas le cas lorsque l'exposition magnétique n'est pas précédée d'un tel traitement. Ledit procédé peut également servir en tant qu'étape supplémentaire dans un processus classique d'extraction des encres de papiers imprimés par reprographie, tel que l'extraction d'encres par classage, flottation, passage en épurateur tourbillonnaire, lavage et sédimentation avec ou sans décantation.

Title: Filter for preventing leakage of electromagnetic wave
Inventor: SATO HIROKI
IPC: H01J17/49
Filed: 1996-10-25
Abstract: A filter (2A, 2C) which prevents the leakage of electromagnetic waves from a PDP (1), and is provided with a filter base (11) in front of the PDP (1) and a grounded conductive mesh (12) which transmits light on the base (11) on the PDP (1) side. A light scattering layer (13) is bonded to the mesh (12) with a conductive adhesive (14) which transmits light, and the spaces of the lattice (where the base (1) exists) of the mesh (12) are filled with the adhesive (14) so that, when electric charge is induced in the mesh (12) by a pulse voltage applied to the PDP (1) for write/erase, the voltage across the lattice of the mesh (12) is made nearly equal to the potential of the mesh (12) so as not to cause electric discharge and generate noise. Alternatively, a transparent antistatic layer (22) is provided between the PDP (1) and the mesh (12) so as not to generate noise by lowering the pulse voltage applied to the PDP (1) for write/erase to such a low value that no electric discharge occurs when electric charges are induced in the mesh (12) by the pulse voltage.
