Patent CA-1141047-A (CA)
Title: Procede pour ameliorer le traitement des fluides sur matieres granulaires
Inventor: ROVEL JEAN-MARIE
IPC: B01D15/04
Filed: 1979-12-07
Granted: 1983-02-08
Abstract: PRECIS DE LA DIVULGATION:         L'invention concerne un procédé pour le traitement de fluides contenant des particules solides en suspension, dans un lit de matières granulaires, notamment de résines échangeuses d'ions, comprenant des cycles de fixation avec un courant de liqui-de de haut en bas et des cycles de régénération des matières granulaires  à contre-courant.  Le procédé selon l'invention est caractérisé en ce que l'on effectue les cycles de fixation et de régénération dans un même récipient dont l'espace intérieur est entièrement occupé par le lit de matières granulaires, et en ce que, lorsqu'un degré prédéterminé de colmatage du lit par les particules en suspension dans le liquide à traiter est atteint, on transfère la partie supérieure du lit contenant lesdites particules, au moyen d'un courant de fluide de haut en bas, du récipient de fixation et de régénération dans un récipient annexe dans lequel on effectue le détassage et le lavage de cette partie du lit; après l'achèvement du détassage et du lavage, on réintroduit la partie supérieure du lit dans le récipient de fixation et de régé-nération.  L'invention permet d'améliorer le rendement des procédés de traitement de fluides sur matières granulaires.  Elle s'applique à toute opération de génie chimique mettant en oeuvre une matière granulaire échangeuse d'ions ou adsorbante qui est soumise à un cycle de régénération après un cycle de fixation au cours duquel on la met en contact avec le fluide à traiter.  De telles opérations sont couramment réalisées par exemple en sucrerie, en hydrométal-lurgie, dans le traitement des eaux résiduaires industrielles, et plus particulièrement pour la déminéralisation des eaux sur résines échangeuses d'ions.

Abstract: MEANS FOR PRODUCING A WATER SPLASH   SHIELD FOR COMMODES, URINALS OR          THE LIKE                       ABSTRACT OF THE DISCLOSURE           The present invention relates to a system for producing a water or fluid splatter shield across an open top area or a toilet bowl, urinal or the like.  This is accomplished by supplying a fluid such as water or air under pressure to a nozzle, an annular ring type housing or pipe that is disposed about the top portion of the toilet bowl or urinal. Outlet means is formed about the interior of the nozzle, the annular ring housing or pipe such that fluid is dispersed therefrom and form a continuous, relatively thin sheet of flowing fluid above the bottom of the toilet bowl or urinal.          Consequently, urine being directed into the toilet bowl or urinal is prevented from splattering out by the presence of the fluid shield.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus is disclosed for controlling final tension on a fastener being run up and set.  An efficiency factor is developed and utilized for attaining predetermined final tension on a fastener, or a group of similar fasteners, being operated upon.  The efficiency factor is a ratio between work on a theoretical fastener, i e., one wherein friction load is absent in work calculations, and work on an actual fastener.          Having obtained the efficiency factor, the actual torque load on a fastener to attain predetermined tension value, can be established by use of the efficiency factor.

Abstract: C A N A D A    Title: LIQUID TREATMENT        APPARATUS               Inventor: LEONARD SYDNEY LOVE                ABSTRACT OF THE DISCLOSURE         The disclosure relates to a liquid treatment apara-tus which includes a clarifier tank and an integral sludge thickener tank.  Liquid enters the clarifier tank through an inlet member disposed generally centrally of the bottom wall of the member and passes upwardly through an eductor member into a mixing zone defined by a reaction cone.  Recir-culation of liquid and suspended particles below the cone pro-motes flocculation of those particles.  Gravity settling also takes place in the relatively quiescent area outside the cone.          The liquid inlet member is of divergent cross-sectional shape for dissipating some of the energy in the liquid and a vari-able speed rotary impeller is disposed in the inlet and can be adjusted to control liquid circulation according to the flow rate of influent liquid.  The apparatus also includes an integral sludge thickener tank to which sludge and liquid are continuously delivered from the clarifier tank.  Clari-fied water from the thickener is returned to the clarifier tank and the effluent from the thickener tank is discarded.

Abstract: RCA 74,389 Abstract In a video disc player intermodulation distortion can occur during signal recovery and is manifested as the modulated sound carrier appearing in the baseband video.  To reduce such distortion, a portion of the signal recovered from the disc record is filtered to extract the modulated sound carrier.  This signal is applied to a phase shifting circuit having a predetermined frequency response to condition the modulated sound carrier to have a phase characteristic substantially similar to the phase response of the-modulated sound carrier appearing as distortion in the baseband video. The phase conditioned sound carrier is then amplitude adjusted and linearly subtracted from the baseband video signal.

Abstract: ABSTRACT OF THE DISCLOSURE       The present invention relates to a television system using a pickup tube performing an oscillatory scan.  On reception the picture restoration device uses a receiving tube which performs a linear restoration, but with a line frequency which is double the scan frequency. In addition, the signal supplied for the pickup tube is processed on reception by two separate processing channels.  The two channels respectively supply first and second aignals respectively corresponding to the low part and the high part of the receiving tube input signal spectrum.  This input signal is then reconstituted by means of an analog mixer.  This leads to a much better definition than that obtained with existing television systems.
