Abstract: Methods for conveying, mixing, leveling, and flaking dewatered pulp to produce pulp flakes suitable to be used in a dryer. Methods for producing a consistent flow rate of pulp, and, for producing uniform pulp flakes in terms of pulp flake size and pulp flake moisture content. A method includes introducing a dewatered pulp to a rotating shaftless screw conveyor. The pulp is deposited from the screw conveyor onto a moving belt conveyor through a chute. The pulp is leveled with a rotary doctor located above the belt conveyor to produce a substantially even rate of mass flow of pulp along a length of belt conveyor. Uniform and consistent quantities of pulp per unit time can then be fed from the belt conveyor to a pulp flaker that then translates into an even rate of pulp mass flow to the dryer.

Patent CA-2499455-A1 (CA)
Inventor: COWAN THOMAS L
IPC: F02P3/08
Filed: 2003-09-18
Abstract: Ignition systems of the kind used to ignite a difficult-to-ignite fuel oil by using energy stored in a capacitor at a breakdown for creating an ignition arc at the electrodes of a spark plug, designed to preclude interference of contaminants with conduction of an ignition arc across an established current path between the electrodes of the spark plug. An air gap and a sparkplug are connected in series, wherein the sparkplug produces an ignition arc in a fuel to be ignited. A first high voltage power supply develops a first direct current voltage across the capacitor, which is supplied as a voltage across the air gap and the spark plug. A second high voltage power supply supplies a second pulsed voltage across the air gap and the spark plug, wherein thesecond pulsed voltage is substantially higher than the first direct current voltage, and the second pulsedvoltage jumps the gap of the air gap and thus initiates an ignition arc, and the first direct current voltage is current limiting thereby allowing the capacitor voltage to approach zero, and thus allowing the air gap to cease conducting, thereby allowing the cycle to repeat itself. A  diode is positioned between the second pulsed voltage and the capacitor of the first high voltage power supply to isolate the capacitor from the second pulsed voltage.

Title: Enhanced girder system
Inventor: REYNOLDS ZACHARY M
IPC: E04C3/18
Filed: 2005-05-19
Abstract: An enhancing mechanism to be placed primarily below the neutral axis of a girder is presented. The movement and deflection of the girder causes the enhancing mechanism to alter the bending moment distribution of the girder. The mechanism is configured so that when combined with the girder, the overall dimensions of the combined system is not much bigger than the dimensions of the girder alone. A tension member may be incorporated into the lower boundary of the enhancing mechanism, and connections are used to attach the mechanism to the girder below the neutral axis. The girder and the enhancing mechanism may be made of the same material or different materials. The compression forces developed in the long diagonal members of the enhancing mechanism become a reaction at the girder end points.  A direct connection of the long diagonal members to support points load shear directly to the end supports.
