Patent CA-2308552-A1 (CA)
Title: Fluid spray apparatus and method for smooth surface gypsum fiberboard panels
Inventor: MILLER DAVID PAUL
IPC: C04B40/00
Filed: 2000-05-16
Abstract: An improved method and apparatus for imparting a smooth surface to gypsum fiber panels. The method involves imparting energy to the surface of a slurry as the slurry is dewatered just prior to rehydration. The apparatus used to impart the energy is a fluid spray including a source of pressurized fluid such as a pump or blower, a distribution manifold and a plurality of nozzles to direct the fluid spray at the surface of the slurry. In operation, the fluid spray is directed against the surface of the slurry. The flow disrupts the slurry to a fraction of its total depth, thus dispersing clumps or flocs of commingled crystals and fibers in the depth that would give the surface of the finished panel a rough surface if they were allowed to remain.

Title: Tree transport machine and method of transporting felled trees
Inventor: JORGENSEN CHAD K
IPC: A01G23/00
Filed: 2000-05-24
Abstract: A tree skidder transport machine and method wherein the machine has a hydraulically operated boom assembly extending rearwardly of a chassis. The boom assembly includes a main boom and a stick boom which cooperate hydraulically to lift the bottom end of a tree, or tree bunch, near the butt, and drag it forwardly over a bogied pair of chassis support wheels. With the further cooperation of a hydraulically actuated heel boom, the tree or tree bunch is then rotated vertically in a counterclockwise direction to lift its top end off the ground and move the tree or tree bunch forwardly a sufficient distance to bring some of the weight of the tree or tree bunch onto the front wheels of the machine.

Title: Gantry-mounted laser nozzle and method for controlling laser positioning
Inventor: ANDREWS RANDALL G
IPC: B23K26/10
Filed: 1998-12-02
Abstract: Method and positioner apparatus are provided for minimizing the time required to move a tool along a continuous path such as over material conveyed continuously thereunder. The continuous path is discretized into geometric moves, pairs of which are preferably joined to minimize positioner stop and go. Ranges of velocities are analyzed for each discrete move and are adjusted to overlap for fitting a continuous velocity curve therethrough.   Optimizing of the velocity ranges for maximum tool acceleration and velocity results in a time-optimized velocity profile for the tool. Velocity profiles for each discrete move are further optimized to maximize acceleration and deceleration resulting in the most time spent at maximum velocity.    Throughout, the method is cognizant of the effects of time and displacement being measured in integer increments. Rounding is appropriately performed and move parameters are adjusted appropriately. Apparatus capable of responding to such optimized control comprises parallel X-rails and a gantry, each end of the gantry being independently driven. Bearings permit the gantry to pivot, resulting translation being accepted by another bearing at one of the ends. Optical encoders on each X-rail and the gantry provide precision positional feedback.

Title: Novel polyethoxylated castor oil, process of making the same and formulations thereof
Inventor: IYER RUPA
IPC: A61K47/44
Filed: 1998-04-28
Abstract: Polyethoxylated castor oil with a low cation content are claimed, along with particular methods for achieving such low cation content polyethoxylated castor oil. One method of production of such a low cationic content polyethoxylated castor oil according to the invention is to pre-treat the polyethoxylated castor oil with a strong cationic exchange resin to remove a substantial portion of the cations present in an untreated polyethoxylated castor oil. The low cationic content polyethoxylated castor oil of the invention can then be utilized to prepare formulations of various agents which are found to be sensitive to the previously commercially available polyethoxylated castor oil (CREMOPHOR EL).
