Patent CA-2148321-A1 (CA)
Title: Drive assembly for a web spreading roll
Inventor: ESKOLA TIMO
IPC: D21F7/02
Filed: 1995-05-01
Abstract: Spreading rolls are used in conjunction with, e.g., finishing equipment of paper mills to assure sufficient and constant cross-machine tension for the web running over guide rolls. Spreading is required due to web width variations caused by the coating, drying and calendering steps. A spreading roll comprises a curved shaft with its radius of curvature vector aligned in the machine direction and rotary driven roll segments mounted in bearings on the shaft. The roll segments are coupled to each other and they are driven about the shaft by a synchronous belt drive. The curvedness of the shaft complicates the design of a synchronous belt drive, and hence, the present invention concerns such a synchronous belt drive assembly for a web spreading roll that is free from angular nonalignment between the driving and the driven toothed pulley. The invention is based on mounting the driven toothed pulley in bearings on the bearing housing of the curved spreading roll shaft and then coupling the pulley with the outermost roll segment using a flexible coupling.

The second fluid supply conduit is positioned concentrically about the first fluid supply conduit  and  the  third  fluid  supply conduit  is positioned concentrically about the second fluid supply conduit.
Patent CA-2150625-A1 (CA)
Title: Cryogenic rectification method and apparatus
Inventor: MOSTELLO ROBERT A
IPC: F25J3/04
Filed: 1995-05-31
Abstract: A cryogenic rectification method for producing a product stream from a gaseous mixture having higher and lower volatility components and heavy impurities. In accordance with the method, the mixture is separated by a cryogenic rectification process employing one or more columns having plates, trays or packing for intimately contacting ascending vapor and descending liquid streams within the column. The mixture to be separated after having been compressed is combined with the recycle stream to produce a combined stream which is purified in a prepurification unit that is designed to remove the heavy contaminants. The combined steam is divided into major and minor streams. The major stream is then cooled and separated into liquid and vapor phases. Heavy impurities concentrate in the liquid phase taken as the recycle stream, which is then pumped to a high enough pressure for vaporization of the impurities. The resulting vapor is then reduced in pressure and combined with the incoming gaseous mixture. The concentration of heavy impurities in the vapor phase is reduced to a sufficient extent such that a product stream concentrated in the lower volatility component will have a reduction in its heavy impurity concentration. The product stream is pumped to pressure and vaporized against a portion of mixture using a boosted pressure subsidiary stream made up of a minor portion of the gaseous mixture.
Patent CA-2150977-A1 (CA)
Title: Implement Caster Wheel
Inventor: HONEY GREGORY J
IPC: A01D41/14
Filed: 1995-06-05
Abstract: A mounting assembly of a gauge wheel for an implement, such as an agricultural crop harvesting header, the mounting assembly including a king pin member rotatably mounted in a king pin bushing housing and having a wheel spindle projecting substantially horizontally from one side of a king pin shaft for rotatably mounting the gauge wheel. The rotational axis of the king pin shaft is tilted rearwardly and upwardly relative to the vertical and sideways and upwardly relative to the verticalin a direction opposite to the side of the projecting wheel spindle. Accordingly, when the gauge wheel enters a caster turn in a direction corresponding to the direction of projection of the wheel spindle the axis of the wheel spindle swings from a substantially transverse direction in relation to the straight ahead travel direction towards a rearwardly and downwardly inclined orientation. A spring is arranged to bias the king pin shaft to turn in a direction counter to a caster turn, and stops are provided to limit the rotation of the king pin shaft between a substantially straight ahead travel condition and a caster turn of a preselected amount of turn. Effective castering of a gauge wheel at the inside of a turn is accomplished together with good straight ahead stability. The structure also allows positioning of the castering gauge wheel close to the framework of the header.
Patent CA-2151551-A1 (CA)
Inventor: SUZUKI NORITAKE
IPC: H01J31/12
Filed: 1995-06-12
Abstract: A method and apparatus for driving an electron source in which a high-quality image display is presented by correcting a non-uniform effective current distribution caused in cold cathode elements by leakage current.  A digital video signal enters a shift register where a serial-to-parallel conversion is made for each line of an image based upon a shift clock signal.  One line of the image data that has been subjected to the serial-to-parallel conversion is latched in a latch circuit and then applied to a voltage modulating circuit.  The latter voltage-modulates the input data and sends the modulated signal to a voltage/current converting circuit.  The latter converts the voltage quantity to a current quantity, which is applied to each of the cold cathode elements of a display panel through respective column terminals.  A voltage V1 is applied to the selected row wire, and a voltage V2 (V2 ? V1) is applied to all other row wires, for controlling the leakage current.
