Patent CA-2097246-A1 (CA)
Inventor: LAPLANTE BENOIT
IPC: B65H18/00
Filed: 1993-05-28
Abstract: The method is for producing a first primary roll having a predetermined lateral surface defined by a diameter Df.   The primary roll is made of material wound around a spindle.  The material is used to produce smaller secondary rolls of material.   The method comprises  steps  of  (a) calculating a portion Sf of the lateral surface, which is covered by the spindle; (b) calculating a portion Si of the lateral surface, which represents material needed to produce the smaller secondary rolls of material: (c) calculating a compression factor K1 which is derived from a compression rate K of a previous second primary roll used to produce previous  secondary  rolls  with  respect  to  the  previous secondary rolls; (d) calculating Df where:                                 (e) winding up material around the spindle to produce the first primary roll until a diameter of the first primary roll reaches said diameter Df; whereby loss of material is reduced by taking into account compression factor K1 which varies with respect to time.  An apparatus to perform the present method is also provided.

Title: Method for identifying optical line
Inventor: INOUE AKIRA
IPC: H04B10/071
Filed: 1993-04-28
Abstract: A method for easily identifying optical lines without error irrespective of the lengths of the lines. A plurality of reflective parts are provided as an identification mark on each optical line. The combination of the correlative positions of the plural reflective parts of an optical line is different from others. The correlative positions of the reflective parts of a line are determined on the basis of the reflected light of the inspecting light incident upon the optical line. According to the results of the determination, the optical line is identified. Mare specifically, when inspecting light is incident on the end. of an optical line, the light is reflected by the plural reflective parts which function as an identification mark, and is caused to return to the incident end. Since the combinations of the correlative positions of the reflective parts are different from each other, the correlative positions of the plural reflective parts of an optical line are found by measuring the differences between the lengths of the optical paths of the optical lines from the reflective parts by use of an interferometer or by measuring the differences in the times for the reflected light to return from the reflective parts.      The optical lines can be identified on the basis of the results of such measurement.

Abstract: ABSTRACT ELECTROLYTIC ETCHING OF METALS TO REVEAL            INTERNAL QUALITY    The internal quality of continuously cast and other steel samples in the form of ingots, billets, blooms, slabs and bars is determined in rapid manner to enable potentially problem-causing casting conditions to be identified and corrected in timely manner.   A steel sample from the casting, after grinding to remove any heat-affected zone and to provide a desired degree of surface roughness,  is anodically etched using dilute hydrochloric acid at ambient temperature to etch away metal from the surface to reveal the internal quality. After removal of the sample from the etching apparatus, the sample is washed, dried, and visually examined to determine the internal quality.

Abstract: An apparatus for balancing and supporting various loads exerted on the pump cylinder block and associated bevel gear in a radial piston type hydraulic transmission for assuring concentric rotation about the pintle during operation.  A hydraulic pressure pad, acting as a hydraulic piston, is located on the outer surface of the pintle at least partially underneath the pump cylinder block hub portion for counteracting the loads exerted against the pump cylinder block and associated bevel gear.  A groove circumferentially disposed in the outer surface of the pintle supplies oil to the pressure pad from a bore disposed in the groove and in communication with the high pressure passage of the pintle.  The pressure pad is preferably disposed 90° from the input shaft and associated input bevel gear. Additional grooving on the outside circumferential surface of the pintle provides lubrication between the rotating cylinder blocks of the pump and motor, and the pintle.

IPC: H01J29/06
Filed: 1994-09-15
Abstract: An improved color picture tube includes an evacuated glass envelope having a faceplate panel with a cathodoluminescent screen comprising different color-emitting phosphor elements disposed thereon. The panel includes a shadow mask-frame assembly mounted therein by support means located at peripherally spaced positions within the panel.      The shadow mask includes an apertured portion, the apertures of which are in register with the phosphor elements of the screen. The support means at each spaced position includes a stud attached to the glass envelope, a spring having an aperture therein for engaging the stud, and a plate welded between the spring and the mask-frame assembly.      The improvement comprises mechanically joining the spring and the plate by extrusions interlocking the parts together at two-spaced apart locations along one edge of the parts, whereby the spring and the plate are in contact along at least a portion of the facing surfaces thereof. The interlocking extrusions render the spring and plate resistant to shock induced movement, thereby minimizing misregister between apertures in the mask and the phosphor elements of the screen.
