Abstract: Un système de commande de convergence pour des modes ou des formats verticaux multiples, ayant des trames respectives à différentes hauteurs verticales, comprend un sélecteur (4) destiné à déclencher le fonctionnement dans un des modes verticaux disponibles, ainsi qu'un circuit (40) destiné à émettre des signaux de correction de convergence répondant au sélecteur. Les signaux de correction sont émis à partir de valeurs de correction de convergence connues et par interpolation des valeurs connues. Les valeurs de correction de convergence peuvent être stockées et traitées de manière séquentielle par des circuits numériques, et l'interpolation peut être entreprise par des circuits analogiques. Le circuit destiné à émettre des signaux de correction de convergence peut comprendre une mémoire (46) de données numériques pour différents ensembles de valeurs de correction de convergence, afin de générer des ensembles pouvant être sélectionnés de signaux de correction pour différents modes ou formats verticaux, par exemple des modes normaux et surbalayés. Les ensembles de valeurs de correction de convergence définissent différents ensembles de lignes de grilles et de rangées de lignes de balayage horizontal. Les lignes de grilles adjacentes sont espacées les unes des autres à différents intervalles pour différents formats verticaux. Les intervalles entre les lignes de grilles horizontales adjacentes sont supérieurs pour les formats verticaux ayant des trames de hauteurs verticales supérieures. Un circuit d'interpolation (40), destiné à traiter les valeurs de correction de convergence connue, répond au circuit de déflection horizontale. On peut ajuster les intervalles d'interpolation afin qu'ils correspondent à la vitesse de balayage horizontal. Le nombre d'intervalles d'interpolation est apparié au nombre de lignes de balayage horizontal se trouvant dans chaque rangée.

Abstract: METHOD FOR TREATING SOLUTIONS IN HYDROMETALLURGICAL ZINC PROCESSING                          ABSTRACT          Dilute   aqueous   sulfate   solutions   encountered   in hydrometallurgical treatment of zinc-containing materials are treated for the control of bulk and for the recovery of metal values.  The solutions are treated by electrodialysis for the recovery of a solution depleted in zinc, usually containing less than about 1 g/L zinc, and other ions for return to the hydrometallurgical treatment, and for the recovery  of  a  solution  concentrated  in  zinc,  usually containing about 70 to 160 g/L zinc, for return to the hydrometallurgical treatment and the recovery of contained values.    To  control  the  ion  concentrations  in  the concentrate    circulating    through    the    concentrate compartments of the electrodialysis unit, a solution such as water,  diluate sulfuric acid, a portion of the feed solution or a portion of the circulating diluate may be added to the circulating concentrate.  Electrodialysis is carried out  under  turbulent  conditions  at  linear  flow velocities from about 3 to 7 cm/s, at about 10 to 500 A/m2, preferably at about 100 to 400 A/m2, and at pH values below about 5.2, preferably in the range of about 3 to 5.

Filed: 1990-01-24
Abstract: ABSTRACT            Method and Apparatus for generating  Cephalometric Images In the generation of a cephalometric images, for example in orthodontic analysis, a probe 13 linked to a computer 1 is used to determine directly the positions of anatomical points of the head 12 of a subject which is held in place by a restrainer 6. The position of the tip of the probe is determined using sonic transmitters 14 and receives 4. The points located by the probe are used to determine the positions of anatomical landmarks for cephalometric tracings including, by means of extrapolation, some that are inaccessible to the probe.          These are then used to produce a cephalometric tracing Which can be superimposed on a video image of the subject's head. The use of x-rays or invasive techniques is avoided.

IPC: G08B29/18
Filed: 1991-07-22
Abstract: A paging receiver having alerting means implemented as a speaker and a light emitting diode (LED). The paging receiver has a decoder for outputting a pair of periodically varying drive signals on determining that a call meant for the receiver has been received, a speaker drive for causing a speaker to sound in the pattern of either one of two drive pattern signals, and an LED driver for turning on the LED in the other pattern.  The drive periods of the two drive pattern signals are arranged alternately with each other and such that they do not overlap each other, whereby the luminance of the LED is maintained at a sufficiently high level even when a battery powering the paging receiver reaches the last stage of its service life.

Filed: 1991-09-30
Abstract: ABSTRACT OF THE DISCLOSURE   A  length of  light weight corrosion  resistant metal  or premolded  plastic structure for the enclosed installation of Christmas light wiring to the eves trough of buildings. The structure is a three inch wide length of metal or plastic with one eighth inch wide notches creating a "T" formation cut into one edge of the material at various distances to accommodate various makes of light fixtures.  Three ninety degree bends are then applied at various locations laterally along the structures length to allow the enclosure of the wire and attachment of the structure to the existing eves trough. The notches are cut into the side of the structure that will abut the eves trough exterior edge, and extend around the bottom inside ninety degree bend to the bottom edge where the notch forms  the  "T"  shape,  thus allowing the extension of the physical  light bulb housing only,  keeping the  power supply cord enclosed internally. The light power supply cord will  have been placed in the inside bend before installation of the structure to the eves trough. The structure is attached to the eves trough by means of corrosion resistant screws applied through the structure's top edge to the top lateral edge of the eves trough and also through the structure's vertical exterior surface into the front top vertical edge of the eves trough.
Patent CA-2054243-A1 (CA)
Inventor: WALTER GEORGE E
IPC: B43M5/04
Filed: 1991-10-25
Abstract: ABSTRACT      A distinct conveyor assembly allows a business form sealer -- such as a pressure sealer -- to operate with forms that have been detached from a continuous supply.  Individual forms are detached from the continuous supply while being conveyed in a first direction, to form shingled forms having irregularly positioned side edges.  The forms are deshingled by conveying them from the detacher at high speed (e.g. an increase in speed of about ten times or more), and they are registered while being conveyed in the first direction at high speed. Registration may take place by moving the forms against one side edge, or moving them between funneled side edges to ultimately engage straight guides on both side edges.  After registration, the forms may be fed directly to the sealer, or into the top of a hopper, and then withdrawn from the bottom of the hopper and passed through a folder before being fed to the sealer.
