Abstract: A dental film-base radiograph which is relatively small of the order of 40 mm by 30 mm is scanned and converted to a digital image by mounting the radiograph on a table movable in single direction at a transparent aperture of the table and by transmitting through the radiograph a beam of laser light from a line source with the line parallel to the radiograph and defining a collimated beam of parallel light at right angles to the line and lying in a single plane containing the line. A detector in the form of linear array of CCD detector elements is arranged in the plane to receive the light passing through the radiograph. The whole is contained in an enclosure to exclude ambient light. The scanning movement can be effected step by step or continuously with the laser source pulsed.

Abstract: A rotary coin mechanism is provided with a braking system in which one end of a stationary brake arm is anchored to the frame of the mechanism.  The other end of the brake arm provides a breaking ring which surrounds the hub of the drive gear and applies a compressive force thereto, to frictionally restrain the drive gear and thus prevent the coin mechanism from free-wheeling rotation. In the preferred embodiment the braking ring is open at one end and merges into a bifurcated stem which provides an adjusting screw to adjust the compressive force applied by the braking ring.

Title: Isometric arm and leg exerciser
Inventor: WALKER DON F
IPC: A63B21/22
Filed: 1996-08-12
Granted: 2004-10-26
Abstract: The invention is an exercise machine (20) for exercising many major muscle groups in the body without stressing the arm or knee joints. An inclined bench (24) mounts rigidly within a frame (22) and in specific relationship to a pair of horizontal axes about which a pair of arm levers (40) and a pair of leg levers (60) pivot, respectively. The arm pivot is located with respect to the bench at the user's shoulder joint, while the leg pivot is located with respect to the bench at the user's hip joint. The rotation of the arm and leg levers (40, 60) may be independent, or may be coupled. The rotation of the arm and leg levers are subject to a torque resistance applied by springs, cables and dead weights, frictional resisted loads, or viscous damping. In one embodiment, the rotation of the arm and leg levers are coupled via a linkage mechanism which drives a locomotive style crank for rotating a flywheel. The flywheel is subject to a braking force by an adjustable means to vary the amount of torque resistance applied to the arm and leg levers.

Granted: 2003-02-04
Abstract: Un segment de pompage d'une ligne de fluide communiquant en alternance avec les parties d'amont et d'aval de la ligne de fluide relie une alimentation de fluide à un récepteur de fluide. Un capteur de pression situé en aval du segment mesure la pression pendant que le segment est en communication avec les extrémités amont et aval. On utilise la différence de pression pour fixer un seuil de pression auquel on compare la pression moyenne en vue de déterminer s'il existe une occlusion en amont. Dans le cas où la pression moyenne descend jusqu'à une zone d'alerte, la pompe est inversée, ce qui permet d'étudier à nouveau la différence de pression. A partir de la différence de pression observée pendant l'inversion, on peut déterminer un seuil qui sera adapté aux conditions d'administration du fluide.

Granted: 2004-05-04
Abstract: The present invention relates to a noise suppressor capable of reducing the noise of a fluid vented at high pressure and high mass flow rate from an industrial source, to the environmentally acceptable noise level. The invention combines two principles of dissipation of fluid stream energy: first, stream pressure is reduced by passing the stream through a swirler to split the stream into a number of smaller tangential streams which dissipate their energy along the spiral flow path due to friction; and next, the resulting streams pass through a tightly packed granular bed to reduce further the pressure and velocity of the exiting jet to atmospheric pressure and subsonic velocity, respectively. Such jet will generate much lower noise level, as compared to high pressure jet with cellular structure and supersonic velocity.

Abstract: A vehicle having a vertical shaft engine mounted to the vehicle frame via elastic mounting units which allow vibratory motion between the engine and the frame for reducing the amount of vibration transmitted from the engine to the frame during operation of the engine. A cooling fan is positioned directly above the engine for pulling air downwardly through a radiator positioned directly above the engine and fan. The radiator is supported in its position above the engine by being rigidly fixed with support members. The support members are rigidly fixed with and extend upwardly from the frame. The radiator is held in position by the support members and is not supported by the engine, and therefore the radiator is generally isolated from engine vibrations by the elastic mounting units.

Abstract: A weapon which employs superelevation of the barrel, such as a grenade machine gun, comprises a barrel unit and an aiming system mounted upon a support. The aiming system comprises an imaging unit, a display unit for displaying an image of a scene within a field of view of the imaging unit, a rangefinder for measuring the range of a target in the f eld of view of the imaging unit, elevation angle measuring means for providing an elevation signal representing displacement of the imaging unit in elevation relative to the support, and a control computer for superimposing upon the image an aiming reticle and a rangefinder reticle, the former representing an aiming point of the imaging unit and the latter representing an aiming point of the rangefinder. The control computer adjusts the position of the aiming reticle in dependence upon the elevation signal, and stores coordinates for selected positions. The aiming system further comprises a coupling unit having a first part connected to the weapon for rotation in elevation with the barrel unit and a second part connected to the imaging unit. The coupling unit has a first state in which the coupling unit fixes the sight unit relative to the support while allowing elevation of the barrel unit relative thereto and a second state in which the coupling unit entrains the sight to move with the barrel unit relative to the support. A switch controls operation of the coupling unit to select the two states alternatively. The control computer computes a required change in elevation of the barrel unit in dependence upon a range measured by the rangefinder a.nd applies a corresponding offset to the displacement signal so as to displace the aiming reticle relative to the field of view in a direction opposite to the change. Where the offset is sufficient to displace the liming reticle beyond limits in the displayed scene, the control computer may be operable apply a part of the onset to position the aiming reticle adjacent a corresponding edge of the field of view and monitor the remaining offset, restoring movement of the aiming reticle with the weapon barrel unit once the barrel unit has been displaced by an elevation angle greater than said remaining offset. The control unit may change the appearance of the aiming reticle while the aiming point is outside the field of view.
