Abstract: ABSTRACT OF THE DISCLOSURE        A process and apparatus for forming a semi-solid thixotropic alloy slurry and preferably a rheocasting therefrom.  Molten metal in a mold is cooled under controlled conditions while it is mixed under the influence of a moving magnetic field.  A non-zero, magnetic field is provided across the full cross section of the mold and over the entire solidification zone.  This results in magnetomotive stirring force of sufficient magnitude to provide mixing of the molten metal to form the slurry.  Preferably, a two pole induction motor stator is used to generate the magnetic field.

Abstract: ABSTRACT OF THE DISCLOSURE The grid frame surfaces of the plate block are bridged in electro-lytically conductive manner. As a result of the forming process, these surfaces exhibit sufficient traces of active mass. A brush-like instrument is used, whose bristles are capillaries which communicate through an electro-lyte container. In a closed multi-cell battery, each plate block is contacted at its grid frame through the filler  opening by the capillaries of an instrument supported above the filler opening. The battery voltage is measured at the terminals. This would otherwise be measurable only after filling with electrolyte.

Abstract: Abstract The present invention relates to a method of selectively treating an article to smooth an edge of the article in an electrolytic bath wherein surfaces of the article, upon being exposed to a wetting treating fluid, are acted upon by the fluid.  The method is comprised of contacting the edge surface of the article to the surface of the wetting treating fluid such that the surface tension of the fluid causes a meniscus to form along surfaces adjacent to the edge surface.  The method further includes vertically positioning the edge surface with respect to the surface of the treating fluid to maintain the edge surface substantially at the surface of the bath and to expose the side faces of the article to substantially none of the treating fluid other than that contained in the meniscus, thereby limiting the action of the treating fluid on the side surfaces.  Finally, the method involves removing the edge surface of the article from contact with the bath of the treating fluid after a time period sufficient to conclude the smoothing treatment by the fluid on the exposed edge surface of the article.

Abstract: TITLE OF THE INVENTION                   BOLT MECHANISMS     ABSTRACT OF THE DISCLOSURE     A bolt mechanism for the door of a safe has bolts which are thrown by a crank arm turned by a spindle connected to an external handle, the crank arm carrying a pin which runs in a drive slot in a bar connected to the bolt strap.  A plate is carried by the bolt of a lock so that when the safe bolts are thrown and the lock operated the plate carries the crank pin clear of the drive slot, the crank arm being slidable transversely on the spindle for this purpose.  This operation isolates the connecting bar from the spindle to prevent the application of force to the boltwork through the spindle in the sense tending to withdraw  he boltwork.

Abstract: EQUIPMENT TO CORRECT ABERRATIONS OF A CATHODE-RAY BEAM      ABSTRACT     Aberrations of an electron beam are corrected as the beam is scanned across the screen of a cathode-ray tube by deriving correction signals from stored digital values by means of the calculus of finite differences.  The digital values, which are the initial differences of polynomial correction functions, are held in store 10 and summed in adder 20, the results being converted by digital-to-analogue converter 50 to analogue signals and supplied to the cathode-ray tube.  Provision is made for the reduction of error in the calculations by shifting higher order differences relative to lower order differences before addition.  The circuitry may be implemented on a single chip.  Preferably the invent-tion is applied to the correction of misconvergence in a shadow mask tube.

The base fabric is primarily comprised of three groups of yarns knit together to form a sheer fabric that creates the visual effect of being woven.  The full weight is formed by incorporating one or more additional groups of yarns into the base fabric.  One group is added to produce a self-lining on the rear side of the material while another group can include a "laid-in" top effect yarn.  This top effect yarn can be fed with varying tension control so that a relatively wide variety of effects can be created.

Abstract: A B S T R A C T   The invention relates to a method of forming a pipe socket having a sealing ring (8) at the inner surface of the pipe socket wall. The sealing ring has a fastening portion (16) and a sealing portion (20) connected therewith. The sealing portion (20) isdisplacable in the axial direction of the pipe socket to be able to take different positions therein in order to adapt to different tolerances.   It is a problem that the sealing portion (20) because of its displacability is not adapted to constitute such a surface around which the pipe wall can be formed. In order to obviate this drawback the pipe wall is formed so that the sealing portion (20) is positioned outside the pipe socket during the forming operation, whereupon the sealing portion is folded into the pipe socket after the forming operation.
