Title: Grinding tools
IPC: B24D5/16
Filed: 1963-06-13
Abstract: 968,816. Abrasive tools. GENERAL MOTORS CORPORATION. June 13, 1963 [July 9, 1962], No. 23592/63. Heading B3D. A grinding tool comprises a cylindrical ceramic head 1 sintered or fused around an end portion of an elongated ceramic shank 2 of smaller diameter than the head, the ceramic of both the head and the shank comprising at least 85% by weight aluminium oxide. The head preferably has a coarse-grained porous structure and the shank a fine-grained non-porous structure and a high modulus of elasticity. The head and shank may be united by means of a layer of a glass. A row batch consisting of about 99.8% by weight aluminium oxide (tabular corundum) and about 0.2% magnesium oxide was ball-milled, the final grain size of the alumina being less less than about 10 microns and 90% being less than 5 microns. About 3% by weight of paraffin wax binder was uniformly mixed into the batch by adding a wax-water emulsion and drying. The batch was isostatically moulded in rubber moulds to form small rods. The rods were fired to about 3000 F. on a 24-hour firing schedule to burn out the wax binder and sinter the ceramic to a dense, extremely hard state having a modulus of elasticity of about 50 x 10<SP>6</SP>. To form the head, 34 grams of 100-mesh aluminium oxide were mixed with 6 grams of 325-mesh powdered borosilicate glass (65% by weight SiO 2 , 23% B 2 0 3 , 5% Al 2 O 3 , 7% Na 2 O) and 4 grams of naphthalene dissolved in 10 c.c. chlorethane. After the chlorethane had evaporated 2.4 grams carboxymethyl cellulose binder dissolved in water were added. After evaporation of the water, a portion of the batch was poured into a cylindrical steel die opening in which the end of a ceramic rod, made as previously described, was concentrically positioned. Pressure of about 10,000 p.s.i. was applied by an annular punch fitted round the end portion of the ceramic rod. The assembly was removed from the die and fired to 1650 F. to burn out the naphthalene and carboxymethyl binder to cause the head to attain a hard, tough, porous condition. Lower pressure, e.g. 5000 p.s.i., may be used and the end portion of the shank may be given a thin layer of glass before forming the head therearound.

Abstract: 1,043,244. Cathode-ray tube circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 13, 1963 [June 20, 1962], No. 23683/62. Heading H4T. In an arrangement -for controlling the dynamic convergence of the beams of a threegun colour image reproducing cathode-ray tube utilizing a convergence magnet arrangement 3 (Fig. 1) comprising separate electromagnets 4, 5, 6 (Fig. 2, not shown) and, internally of the tube, associated polepieces 10, 11, 12 respectively, the energizing currents for the magnet windings are derived from summing amplifiers 25, 27 having as inputs parabolic waveforms produced by integrating at 23, 24, line and frame frequency sawtooth waveforms from the scan circuits 21, 22 respectively. The relative amplitudes of the line and frame frequency components supplied to the amplifiers 25, 27 depend on physical parameter of the tube and its deflecting coil system are determined by the position of the tapping points on potential dividers 26, 28 which may be pre-set. Adjustment of the circuit is then effected by a single manual control 20 operating on ganged linear potentiometers 15, 19. Alternatively, the two inputs to each summing amplifier may be controlled by respective ganged linear potentiometers and, instead of using summing amplifiers, separate suitably proportioned windings on the convergence magnet may be supplied with the line and frame frequency parabolic waveforms.

Abstract: 1304399 Packaging ACI OPERATIONS PTY Ltd 15 May 1970 [15 May 1969] 23770/70 Heading B8C Separating strips 11 for insertion between bottles in a carton are severed at the inserting station from continuous lengths 14 and are then pushed down between the bottles by pincers 18, 19. A conveyer passes loaded cartons below a number of inserting stations at each of which strips are inserted at right angles to the strips of the preceding or succeeding stations. The conveyer may stop when a carton is below an inserting station' or the conveyer may move continuously, in which case the inserting mechanism moves with the conveyer during insertion. At an inserting station, each continuous length 14 is fed by rollers 15 until a microswitch 17 is contacted to stop the rollers and operate the severing device 25. Fixed guides 16 maintain the strips vertical, and retractable guides may be provided to support the lower edge of the strip until the latter is gripped by the pincers 18, 19. All the pincers at one station are linked, Fig. 5 (not shown), so that they operate in synchronization to push the strips down between bottles located on centres 10.
