Title: Robotic centering device
Inventor: ST DENIS CARROLL ROBERT
IPC: G05D3/12
Filed: 1996-02-27
Granted: 1998-06-16
Abstract: A circular robotic device has retractable extendible surface engaging drives controlled by linear actuators.  A pressure transducer indicates the pressure exerted by one such drive on the surface if the pressure is to high the drives are retracted, if the pressure is too low the drives are extended.  A more sophisticated version controls the pressure exerted by each drive independently. In a pole centering version this providing a tight clamp allows the device to climb and descend the typically tapered poles.  The device can prime and paint poles to predetermined thicknesses, as well as sandblast the poles.  In a pipe cleaning version the drives engage the internal surface of a pipe.  The pipe cleaning version carries pipe cleaning and/or X-ray equipment.  A microprocessor monitors the device and provides status information to a remote control unit.

Inventor: TOURNIER HERVE
IPC: A61K49/18
Filed: 1996-06-14
Granted: 2008-09-16
Abstract: The invention concerns NMR imaging contrast compositions comprising magnetically responsive species coupled to physiologically acceptable amphipatic organic substrate materials in the form of mixed micelles suspended or dispersed in a physiologically acceptable aqueous liquid carrier. The compositions are particularly useful for diagnostic investigations of the blood-pool. The invention also concerns the preparation of the mixed micelles, as well as of injectable compositions containing the mixed micelles as contrast agents for MRI  purpose. Once injected, the mixed micelles of the compositions behave as imaging contrast enhancers, e.g. they will improve the quality and resolution of the electronically processed images obtained during MRI  examinations of the circulation and/or circulation targeted organs.  The compositions are formulated to protect the particles of the contrast agents from early removal by the reticulo-endothelial (RES) system of the liver and the spleen, so that they will stay in the circulation for a time sufficient to properly image the blood vessels and to be transported to selected organs. MRI imaging of the circulation and of targeted organs can strongly assist in diagnosing possible ailments in human and animal patients.

Abstract: A flow meter, such as is used in warm water heating systems, has a measuring element (2) with a flow-responsive element and a display element (3) with a transparent inspection glass or tube (10) with a bore in which an an end of an indicator rod (6) moves.  The indicator rod is part of, or is coupled to, the flow-responsive element and it has a pointer (8) near the end inside the inspection tube.  The inspection tube preferably has no markings; instead, around the inspection tube is a scale support (16) with scale markings calibrated to the positions of the pointer (8) to show the amount of flow.   The scale support is essentially sleeve-shaped, with a lateral cutout (18) which permits the user to view the pointer inside the inspection tube.  The scale markings may be on cut surfaces (20) adjoining the lateral cutout.  In one embodiment the scale support is rotatable about the inspection tube for adjusting the viewing angle, so that it is not necessary to take the rotational position of the inspection tube into consideration when the flow meter is installed.  In an alternative embodiment the inspection tube is combined with a valve for  adjusting the measured flow.
