Abstract: 499,197. Transformers. BAGNALL, R. I., and FOSTER ENGINEERING CO., Ltd. June 15, 1937, No. 16597. [Class 38 (ii)] In an on-load transformer tap changing arrangement the tap changing switch is arranged in the form of a commutator, the tappings being connected to the segments 2, Fig. 1, mounted on a support 1, current being collected by means of a brush 11 which is made wide enough to bridge the insulation between adjacent contacts and has a non- uniform specific resistance such that the resistance of the brush to the flow of load current is less than its resistance to the flow of circulating current which occurs when the brush bridges a pair of elements.

Title: Improvements in or relating to the manufacture of dyestuffs of the anthraquinone series
IPC: C09B5/28
Filed: 1934-06-04
Abstract: Anthraquinonecarbazole dyes are prepared by fusing pentanthrimide (tetra - a  - anthraquinonyl-1.4.5.8-tetraminoanthraquinone) with aluminium chloride at about 175--200 DEG  C. in the presence of a cheap, water-soluble, fusible inert salt such as sodium chloride and preferably in the presence of an alkali metal carbonate and then oxidizing the product for example by means of chromic acid.  In an example, a  - pentanthrimide is fused at 180--190 DEG  C. for a short time with sodium-aluminium chloride and in presence of a little soda ash; the mixture is oxidized by means of sodium dichromate and concentrated sulphuric acid to give a yellow-olive dye.  The a -pentanthrimide is prepared by chlorinating 1.5-dinitro-4.8-dichloranthraquinone to give the 1.4.5.8-tetrachloro derivative and condensing this with 4 molar proportions of a -aminoanthraquinone.  German Specification 262,788 is referred to. The Specification as open to inspection under Sect. 91 relates to carrying out the above treatment at a temperature below 270 DEG  C. and preferably in presence of a suitable carbonate.  This subject-matter does not appear in the Specification as accepted.

Abstract: 699,709. Grinding curved slots. HJELMBLAD, K. W. J. July 18, 1951 [Aug. 17, 1950], No. 17089/51. Class 60. A method of finishing a previously-formed spiral groove 3 in a cam plate for adjusting the jaws of a chuck and the like comprises grinding the concave and convex walls 4, 5 of the groove with the conical working-surfaces 9 of grinding tools 8. During the grinding operations, both the workpiece 1 and the tool 8 are rotated and either the workpiece or the tool is traversed ; the tool may also be reciprocated continuously between the top and the bottom of the slot during operations on the walls, or be arranged to make constant contact over the full depth thereof. In finishing the concave wall 4, the arrangement must be such that, for all points in the length of the wall, the radius of curvature of the line of intersection 12, Fig. 2, of an imagined extension of the surface 9 and a plane 7 passing through the bottom 6 of the slot is less than that of the line of intersection of the plane 7 and the wall 4. The axis 11 of the tool 8 should preferably intersect the plane 7 between the groove and the axis of curvature 15 of the wall 4. An analogous arrangement applies during grinding of the convex wall 5, Fig. 3, with the radius of curvature of the wall being less than that of the projection of the conical surface 9 and the axis 11 intersecting the top-surface of the workpiece at a point 17 outside the range between the groove and the axis of curvature 18 of the wall. The wall 5 may also be ground by a tool similar to that of Fig. 1. The bottom 6 of the groove may be ground by two separate tools, each designed for use adjacent one of the walls, or by a single tool, Fig. 6, incorporating the essential features of the separate tools. The radii of curvature of the lines of intersection of imagined extensions of the conical surfaces 20, 21, bounding the working surface 19 of the tool, and the plane 7 are related to the radii of curvature of the walls 4, 5 in the same way as are the surfaces 9 of the tools for grinding the walls 4, 5 respectively. Slots of other than constant width and having a sloping bottom may be finished.
