Inventor: CONTI JAMES C
IPC: A61B8/06
Filed: 1990-12-28
Abstract: An ultrasound calibrator apparatus and method for calibrating ultrasound equipment. The apparatus includes a pair of opposed bellows (41,43) oscillatorily transferring a fluent medium back and forth through a channel (47) with a well-defined cross-sectional area such that the flow velocity therethrough is known. A probe (116) in communication with ultrasound equipment (117) to be tested is submerged in a reservoir (45) which is situated in close proximity to the channel (47) such that the flow velocity can be measured therewith. The ultrasound equipment (117) is then adjusted to correct the discrepancies between the known and measured velocities so as to calibrate the ultrasound equipment.

Abstract: A process for shearing to length steel bars coming from a rolling mill comprises the steps of: feeding the continuous rolled product to a first collecting chamber, which is a part of a braking/distributing apparatus which brakes and distributes the sheared bars and comprises a plurality of said chambers, which are stepwise mobile in sequence, in phase with the shearing of the bars; shearing to length a first bar and introducing the leading end of a second bar, following the first bar, to a second collection chamber; shearing to length said second bar and, by means of the shifting of said collection chambers, discharging said first, braked bar onto conveyor means. 
     A facility for practicing the above briefly disclosed process comprises the combination of at least one shear (10), for shearing to commercial length the bar exiting the rolling mill and of a braking/distributing apparatus (11) for braking the sheared bars and distributing them onto conveyor means which perform the task of sending said bars sheared to length, while simultaneously cooling them, to devices where bundles or   bars are formed, tied and stored. 
     The apparatus (11) can comprise, e.g., a plurality of coaxial drums (13) each provided with circumferential seats, or collection chambers (16) inside which a bar (17) sheared by the shear (10) is received and braked by means of braking means The operation of the shear and the rotation of the drums (13) take place in phase, so that at each operating cycle a bar is discharged from the drums (13) onto the conveyor means.

Abstract: An apparatus and method for sizing and separating particles of a material is disclosed. The apparatus includes a stand (2), a frame (3) having a fair of ends and an intermediate portion, and suspension assemblies (4) attached to the stand and the frame for movably suspending the frame on the stand. A pair of inclined screens (6) are removably mounted in a pair of screen boxes (55) removably mounted on the frame, with each of the screens sloping downwardly from the intermediate portion of the frame toward a respective one of the ends of the frame. One or more motors (5) is mounted on the frame for vibrating the frame and attached screens, and a feed box (65) is mounted on the stand adjacent to the above upper ends of the screens for supplying a material to be sized. The method of the invention includes the steps of actuating the motor arid depositing a material onto the upper ends of the screens via the feed box, so that the vibrating screens can simultaneously size and separate particles of the material. Spacers (46) can be inserted between the stand and certain ones of the suspension assemblies to effect small changes in the slope of the screens, if needed, for generally equalizing the rate of movement of a material on each of the screens. The screen boxes can be replaced to effect gross changes in the slope of the screens, so that the apparatus can be used in different particle sizing applications.

Abstract: In the process for the preparation of catalysts for hydrogenation/oxygenation, dehydrogenation and dehydration processes from pure or mixed oxides of nickel, cobalt and molybdenum, vanadium, tungsten, titanium and chromium from the aqueous solution of the corresponding chlorides, fluorides or nitrides, the solutions are introduced into a pyrohydrolysis unit, where the desired oxides are formed with specific surface areas of between 1 and 100 m<2>/g, agglomerate sizes from 1 to 500 micrometers and a mean particle size of between 20 and 30 micrometers, and the anions are combined with to hydrogen to give the corresponding acids. These can advantageously be recycled again into the chemical dissolution process. As a further process step, this can be followed by a pre-reduction at high temperature not exceeding 800 DEG C. The catalytically active substances can also be deposited on support matrices such as aluminium oxide, titanium dioxide, phosphorus pentoxide or silicate-type supports. Simple further processing to shaped forms (pellets etc.) is possible.

Abstract: Procédé permettant de déposer uniformément un matériau sur toute la surface périphérique externe d'un organe rotatif à l'aide d'un robot. Un matériau est éjecté d'une tuyère en direction d'un organe rotatif, pendant que la tuyère (2) d'un appareil à matériau fluide montée à l'extrémité d'un bras de robot se déplace le long de la surface périphérique externe de l'organe rotatif, tel qu'un tronc de cône (1) tournant à une vitesse déterminée. Un appareil de commande de robot calcule (S12) périodiquement les valeurs de coordonnées (x, R, O) dans le système de coordonnées de travail, comprenant une position de déplacement de la cible (x) dans le sens de l'axe de rotation de la tuyère dans le système de coordonnées de travail (P5-XWYWZW) exprimé par une fonction du temps écoulé depuis le point de départ du dépôt de matériau. et une position de déplacement de la cible (R) dans le sens radial de la tuyère correspondant à la première position. Ces valeurs de coordonnées sont transformées (S14) en celles d'un système de coordonnées relatives à un robot (OB-XBYBZB), qui sont transformées (S15) à leur tour en des données d'axe de robot. On effectue en outre une distribution d'impulsions en fonction de la distance de déplacement de chaque axe du robot pendant cette période que l'on calcule à partir des données susmentionnées et des données de la période précédente (S16 ~ S18). Grâce à cet agencement, la tuyère montée sur le bras du robot se déplace à une vitesse variable le long de l'axe de rotation proportionnellement au diamètre externe de l'organe rotatif, et le matériau est déposé de manière uniforme selon l'épaisseur désirée sur toute la surface périphérique externe de l'organe rotatif.

Abstract: In a turning control apparatus for a vehicle (82), a torque calculation unit (51, 56) calculates a target lateral acceleration of the vehicle (82) according to detection signals from a steering angle sensor (84) for detecting the direction of a steering wheel and a vehicle speed sensor (80, 81) for detecting the speed of the vehicle (82). It then sets the target driving torque of the engine (11) according to the target lateral acceleration. An electronic control unit (15) controls the operation of a torque control device (76) for reducing the driving torque of the engine (11) so that the driving torque of the engine (11) is a target driving torque independent of manipulation by the driver. This thereby rapidly estimates the lateral acceleration applied to the vehicle (82) during turning and prevents the control delay to enable stable and positive travelling through a curved road.
