Patent CA-2487233-A1 (CA)
Inventor: KING FREDERICK DAVID
IPC: G01N15/02
Filed: 2004-11-10
Abstract: A system and method for measuring small particles suspended in a fluid are disclosed. The system employs optical imaging using diffraction enlargement. A sample of small particles illuminated by a light source is imaged onto a pixel array of detector elements using an imaging optical system having a reduced magnification not sufficient for forming a large enough image of a smallest particle of interest. A low- aperture imaging optics with NA < 0.05 is used to add diffraction enlargement to the image corresponding to at least 5 pixels to enable accurate measurement of images of smallest particles of interest, and to increase an optical sampling volume. Suitably programmed processor is used for determining at least a pixel count for each of the diffraction- enlarged images, and for generating a number, size or distribution of particles accounting for pre- determined diffraction enlargement of particle images of different sizes. The method enables analysis of large samples of small particles in one measurement.

Title: Method for determination of optimal spin axis for a log for peeling in a veneer lathe
Inventor: HYYSTI MIKA
IPC: B27L5/02
Filed: 2004-11-17
Abstract: The invention relates to a method for centering a log for veneer peeling in a lathe. In the method the log is first centered in the centering arrangement of the lathe equipment using centering alignment data based on the contour of the log. On the basis of the thus determined centering data, a computer simulation of peeling is carried out and the results thereof are displayed.  The operator performs an alternative centering based on visual evaluation of the log end and, using this centering data, another computer simulation of log peeling is carried out. The peeling outcomes are displayed as an image. The peeling outcomes of all simulations are compared with each other and the centering of actual peeling operation is performed using the centering data giving the optimum yield of peeling.

Abstract: To correct the tooth profile error of a ground gear, the wheel angle of a threaded grinding wheel is modified by dressing the threaded grinding wheel by a dressing device. To correct the helix form deviation of a ground gear, namely, to modify the helix angle of the gear, synchronization between the moving motion in the Z-direction of the threaded grinding wheel and the rotary motion of a table for installation of the gear is adjusted. When the helix form deviation is corrected by adjustment of the synchronization, a tooth profile change inevitably occurs. In consideration of the tooth profile change, correction of the tooth profile error by dressing is made.
