Granted: 1992-08-04
Abstract: ABSTRACT OF THE DISCLOSURE By adding an appropriate amount, 1 to 12 weight percent, based on the amount of magnesium oxide present and Loss On Ignition values of powdered magnesium metal to the magnesium oxide aqueous slurry composition used to make a separating-agent composition in the making of grain-oriented silicon electrical steel, there are obtained composition, an article, and a method characterized principally by a substantial decrease in the rate of rejections of the product of the final texturizing anneal because of coating defects - such difficulties as bare spots, and metal-overlay pattern.  Moreover, the magnetic properties may be improved because of improved control of the propagation of the internally oxidized zone of the steel.

Title: Method and apparatus for measuring deviations from flatness
Inventor: SHELANGOSKIE DONALD R
IPC: G01B7/34
Filed: 1987-11-12
Granted: 1992-02-04
Abstract: ABSTRACT OF THE DISCLOSURE Deviations in flatness on a horizontal surface are measured by running over the surface, at a constant driven speed, an instrument sensitive to slope and which generates a continuous voltage signal corresponding to a continuous slope measurement. Th continuous voltage signal is filtered to remove extraneous high frequency voltage signals thereby to produce raw continuous analog slope data which is digitized and calibrated to provide calibrated digital slope data from which other flatness data is computed. Procedures are described for calibrating the instrument and for eliminating or compensating for distortions in the measurements.

Abstract: PROCESS FOR THE STRUCTURAL REINFORCEMENT OF FRAGILE MANUFACTURED ARTICLES MADE OF STONE OR IN GENERAL AGGLOMERATES AND PRODUCTS OBTAINED THEREFROM        ABSTRACT OF THE DISCLOSURE           The process provides for the structural reinforcement of manufactured articles made of stone or, in general, agglomerates by means of a sequence of steps which comprise the following:  a)  the article to be treated is heated;  b)  spraying on one surface of the article a particular adhesive called primer;  c)  spraying on the same surface a resin preferably containing glass fibers or fibers of another material;  d)  spraying on the same surface grit of stone having a constant and defined granulometry;  e)  applying an action of vibration or compression on the article in order to facilitate the cohesion of the grit with the resin;  f)  letting the resin undergo a catalytic reaction which eventually may require application of heat;  g)  levelling the surface by mechanical operations.  The same process may be repeated on the other surface of the article if one desires to cut the article along its thickness for the purpose of obtaining a very thin product.  The process is also applicable to agglomerated articles for the purpose of obtaining very thin products and of limited weight while the mechanical and aesthetic properties remain unaltered. The product obtained by the process of the application offers structural properties substantially superior to the properties of the starting articles and the process permits to utilize material which is structurally weak and defective.

Abstract: MICROPROCESSOR CONTROLLED THERMAL PRINTER                 ABSTRACT           A microprocessor controlled thermal printer particularly usable in a hand-held labeler for printing labels on a composite web detects indices on the web and utilizes the detected indices to position the labels relative to the print head.  The printer uti-lizes an improved index detection system that compen-sates for variations in index size and density and for variations in sensor sensitivity by detecting both the leading and trailing edges of an index and utilizing the distance between the detected leading and trailing edges to determine the length of the index.  By dividing the length thus determined by two, and by advancing the web by this amount after the detection of the leading edge of an index, the center of the index can be accurately located, and the web can be accurately registered at any desired position relative to the center of the index.

Title: Crt focus utilising magnetic means
Inventor: JOSHI SHRIKRISHANA N
IPC: H01J29/64
Filed: 1989-09-29
Granted: 1993-07-20
Abstract: ABSTRACT     The focus of an electrostatically focused CRT may be improved by placing a split resilient ring around the neck of the CRT having radiating posts which receive ring magnets magnetised across their diameter.  The ring may be translated along the neck of the CRT in the vicinity of the cathode and the magnets oriented to bunch the electron beam from the cathode and move it onto the axis of the focusing electrode.   Bunching improves the electron density distribution within the spot.  The magnet mounted on the ring may be turned to counteract the perturbations due to the excessive field penetration of the yoke in the low beam velocity region.  A d.c. bias is added to the yoke current to compensate the resultant offset picture.  After positioning of the ring, it may be glued in place.
