Patent CA-2206242-A1 (CA)
Inventor: WINDER ALAN A
IPC: A61H23/02
Filed: 1995-02-17
Abstract: A transducer (10) for non-invasive transcutaneous transmission of pulsed ultrahigh-frequency acoustic radiation, in body tissue and/or fluids adjacent a bone fracture is "on target" when a fraction of the propagated energy within the longitudinal-response lobe of the transducer encounters a gap or space between closely spaced fracture walls. The ultrahigh-frequency acoustic radiation sees this "on target" feature as the entrance to a waveguide, whereby pulsed ultrahigh-frequency acoustic radiation is guided within the crack. When this acoustic radiation encounters a gap of at least a quarter wavelength (at the ultrahigh frequency), a standing wave condition establishes itself, with dissipation of the ultrahigh frequency and with demodulation to establish a therapeutically beneficial low-frequency acoustic condition, within the fracture, and acting where most needed, namely, on and between wall regions of adjacent fragments of the broken bone.

Abstract: Un fût de stockage bisecté longitudinalement (10) comprend une paire de segments de fût semi-cylindriques (12, 14) constitués chacun d'une paire de panneaux d'extrémité semi-circulaires (12a, 14a, 12b, 14b) qui sont fixés à une paroi latérale comprenant une section de paroi semi-cylindrique (12c, 14c) et une section de paroi sensiblement rectangulaire et plane (12d, 14d) et séparés par ces dernières. La section de paroi plane d'un segment de fût définit une rainure rentrante (14e) orientée longitudinalement qui s'assemble avec une languette (12e) orientée longitudinalement et saillant de la section de paroi plane du segment de fût. Ainsi, lorsque la languette est dans la rainure, une structure de fût globalement cylindrique est formée. Les sections de paroi planes et rapprochées de chaque segment de fût forment une surface de séparation diamétrale lorsque la languette est dans la rainure, les segments de paroi semi-cylindriques étant dotés de paires saillant vers l'extérieur et espacées longitudinalement de butoirs escamotables (12g, 14g, 12h, 14h) à proximité de cette surface de séparation. Ainsi, par le simple fait d'inverser l'orientation des trous de bonde (12j, 14j) formés dans chaque panneau d'extrémité supérieur (lorsqu'on fait tourner le fût le long de sa paroi latérale cylindrique jusqu'à ce que ce dernier repose sur l'autre ensemble de butoirs escamotables) le contenu des segments de fût semi-cylindrique peut être distribué de manière sélective par positionnement du trou de bonde du segment en position verticale inférieure par rapport à l'autre trou de bonde.

Filed: 1996-05-15
Abstract: A universal radiographic/fluoroscopic "room" (100) is constructed by combining X-ray examination system components, electrical and mechanical drive components, and sensing components, under the supervision of a control system (510), to form a universal diagnostic medical imaging system capable of performing radiographic, fluoroscopic, tomographic, and stepped examinations in several different operator-selectable configurations. The control system (510) automatically determines which system components are required to perform that type of examination, moves the components into operational or storage positions as required, and prepares each component for operation. In the "stepped-digital" modes, an X-ray tube (182) and image intensifier (166) execute a series of radiographic exposures at preselected locations. For each step, a test fluoroscopic exposure is performed under automatic brightness control to determine an optimum technique. The technique so determined is converted for use in subsequent radiographic exposure.

Title: Process for separating multivalent metal ions from autodeposition compositions
Inventor: HAAS CHRISTINA M
IPC: B01J39/04
Filed: 1996-04-12
Abstract: The use of selected cation exchange resins to remove dissolved multivalent cations such as iron, zinc, and chromium from used autodeposition compositions permits reuse of the autodeposition compositions without the need for added surfactant and without developing any undesirable graininess or other texture in the coatings formed. Iminodiacetate cation exchange resins are very effective for removing iron ions when they are the only multivalent ions to be removed, and can be efficiently regenerated with 0.5 to 4 % by weight aqueous hydrofluoric acid. By proper choice of other cation exchange resins and operating conditions, zinc can be selectively extracted from autodeposition baths containing both iron and zinc, and either iron or zinc can be selectively displaced from the loaded ion exchange resin.
