Abstract: ABSTRACT     A hopper car gate opener comprising an elongated member having opposed flanges defining a fixed track; a trolley element mounted on the track supported by and movable along a top surface of each flange; and a portion of the trolley element underlaying  and spaced from a bottom surface of each flange.  A torque producing unit is mounted on the trolley element and is operable to generate a twisting moment in a predetermined rotational direction to drive a pinion of the gate.          A method of operating the discharge gates of a hopper car having a plurality of gates where the gates are under control of rack and pin-ion sets individual thereto; providing a flanged track disposed gen-erally parallel to the longitudinal axis of the car; mounting a trolley upon and movable along the track; and mounting a torque producing unit upon the trolley.  The method additionally comprises positioning the trolley along the track so that the torque unit is aligned with the pinion, and connecting the torque unit to the pinion by means of an elongated shaft so that torque applied to the shaft drives the pinion which, in turn, drives the rack to operate the gate.

Abstract: HAMMER MILL FOR WHOLE GRAIN FLOURS            ABSTRACT OF THE DISCLOSURE           Conventional grinding of whole grain flour such as whole wheat flour, is by conventional milling procedures.  However, these cannot fully grind the bran due to the fibrous content thereof, to the same fineness as the remainder of the grain so that the bran remains as a larger fraction in the finished product.  The present device utilizes a hammer mill with a relatively fine screen.  In order to prevent moisture and flour forming a dough and caking around the re-circulating air intake, a seal is provided around the intake to prevent this flour and the moisture from mixing.  The air enters through the sealed area and cannot mix with the flour.  An exhaust duct is also provided to atmosphere together with a dust separator and the flour dust from the separator is fed back to the hammer mill outlet through which whole grain flour exits from the mill.  This arrangement produces a whole grain flour in which all components including the bran are of the same maximum fineness.

Abstract: Procédé de commande du débit d'air à l'admission d'un moteur thermique alimenté par injection de carburant, le débit d'air étant régulé en fonction de la vitesse de rotation du moteur, notamment au voisinage de sa vitesse nominale de ralenti, caractérisé par le fait que la valeur de consigne de la régulation est constituée par le résultat d'un filtrage effectué sur une grandeur liée à la valeur instantanée de la vitesse de rotation du moteur, suivi d'une moyenne pondérée entre la valeur filtrée et une grandeur liée à la vitesse minimale de ralenti. Le dispositif de commande pour la mise en oeuvre de ce procédé comporte d'autre part un dispositif permettant de faire varier le débit d'air dans le conduit d'admission, un actionneur lié au dispositif permettant la variation du débit d'air pour commander ce dernier, un système asservi à l'actionneur introduisant une correction proportionnelle intégrale au signal d'entrée de l'actionneur, et un régulateur recevant un signal fonction de la vitesse de rotation du moteur thermique et produisant un signal possédant une fonction de transfert du type: <IMG> lequel constitue le signal d'entrée du système asservi, p étant l'opérateur de Laplace, T et k étant des cons-. tantes. Ce système a l'avantage d'amélioler le fonctionnement de la régulation du débit d'air à l'admission en particulier lors des phénomènes transitoires en apportant une anticipation dans la commande de l'actionneur de la vanne de régulation.

Abstract: Abstract The invention relates to a means for compensating for variations in matrix height and/or paper thickness on a rotary printing press, especially intended for a rotogravure printing press comprising pairs of cooperating rollers/cylinders.  One or more inking rollers transfer the primary colour (or chemicals, coating composition, lacquer, etc.) to a matrix mounted on a matrix cylinder which cooperates with the inking roller and is adapted via the matrix to transfer the ink or other substance to a moving web of paper which passes over a counterpressure cylinder adapted to press the paper against the matrix during the ink transferring process.  The center-to-center distance between the axes of cooperating pairs of rollers/cylinders is in a manner known per se adjustable to varying matrix and/or paper thicknesses.  The compensating means is based on the use of flexible support rings which are compressed and further reduce the center-to-center dis-tance(s), or nip, between the rollers.  The flexible support rings are elastically deformed as they are compressed during the initial adjustment of the roller nip until equilibrium is reached at the desired center-to-center distance between the two rollers in the pair.  The compensating means is flexible around this nip width (the initial or basic adjustment) and can thereafter adjust and accom-modate to small variations in matrix and/or paper thickness.  The compensating means comprises flexible members that constitute part of the support means for the cooperating pairs of rollers/cylinders.          Upon a reduction of the center-to-center distance from the initial adjustment position, the flexible members are formed and/or adapted to be compressed with elastic, resilient deformation.

Abstract: ABSTRACT OF THE DISCLOSURE          In a time base corrector  incorporated in a VTR, if a time during which a vertical synchronizing signal  is  written  in  a  memory  unit  exceeds  one horizontal period segment,  the video signal stored at the first address of  the memory unit is dropped out during data reading operation.   To overcome the above problem,  a write  address  designation signal  is once latched in response to a vertical synchronizing signal; a predetermined number is subtracted from the latched address number; the subtracted address number is loaded in  a  counter  in  response  to  a  reference  vertical synchronizing signal and is incremented in response to a reference horizontal synchronizing signal  in order to shift  the  read  start  address,  thus preventing video signals stored in the memory unit from being dropped off.

Abstract: ELECTRIC ARC SPRAY METALIZING APPARATUS                Abstract of the Disclosure An electric arc spray metalizing apparatus includes a spray gun which delivers a metalizing coating to the substrate, and a wire feed drive mechanism which pushes wires to the spray gun through cables.  The wire is pushed by a pair of drive contact rollers or devices which are con-nected in a tandem relationship and operatively contact each wire to individually impart driving or pushing force to the wire.  The wires are directed at the spray gun to an intersection point where electrical energy creates an arc for consuming the ends of the wires at the intersection point.  The wires are electrically charged by contact with a curved wire guide as the wires are bent when pushed through the wire guide.  A flow stream of pressurized gas is directed onto the intersection point and the molten metal of the consumed wire ends is directed in a spray stream of molten metal particles.  A pair of deflecting streams of pressurized gas influence the spray stream by deflecting it into an elliptical or elongated deposition pattern.  The orientation of the spray stream and deposition pattern can be changed relative to the spray gun by rotating a deflec-tion housing which creates the deflecting streams.  The wire feed drive mechanism includes a housing for shielding the interior elements from the ambient environment, and a supply of pressurized gas is directed to the interior of the hous-ing to prevent the entrance of airborne particles.
