Title: Improvements in and relating to abrading tool structures
Inventor: HARRIS WILLIAM HASTE
IPC: B24D7/00
Filed: 1966-01-19
Abstract: 1,139,522. Abrasive tools. DEXCO CORP. 19 Jan., 1966, No. 2412/66. Heading B3D. An abrading tool structure is formed by heating a substantially oxide free base member in non-oxidizing conditions, and flame spraying grits of abrasive material and matrix material on to the heated base member. The surface 30 of a substantially rigid substrate 22, e.g. of steel or the like, is preferably shot blasted. The surface is heated to approximately 200‹ F. by a torch or in an oven in a non-oxidizing atmosphere. Fused particles of a bonding metal, e.g. Nickel-Chromium-Boron alloy, may then be applied, by flame spraying or a metallizing gun, to the hot surface to form a layer 0À001-0À005 inch thick. The layer may be re-heated to fusion temperature to densify it. Abrasive grits and a relatively small quantity of matrix are applied by flame spraying. For relatively coarse grits an oxyacetylene flame can be used; for relatively fine grits, e.g. 300 mesh, hydrogen can be used. The grits may be aluminium oxide, silicon carbide, tungsten carbide, titanium carbide or garnet. The matrix may be particles of a Nickel-Chromium- Boron alloy, which may contain iron and silicon; when the grit is tungsten carbide the alloy preferably contains molybdenum and cobalt. With relatively coarse grits, e.g. 90 mesh, the mixture of grits and matrix particles should contain a maximum of 40% matrix particles by volume; with relatively fine grits, e.g. 320 mesh, the mixture should contain a maximum of 5-10% matrix particles by volume. The maximum size of the matrix particles should not be greater than the size of the grits. With grits coarser than 90 mesh two guns may be used, one spraying grits and the other spraying matrix, the sprays merging before reaching the surface. Grits of 90-320 mesh may be given a very thin coating of matrix and mixed with matrix particles of the same size. Alternatively, matrix-coated grits may be sprayed on the surface, a layer, e.g. 0À001 inch thick, of matrix flame sprayed over the grit layer, and the surface heated to white (for 90 mesh) to cherry red (for 140 mesh) or to dull red (for 320 mesh) for a very brief period. The surface is then wire brushed to clean it. In the resultant product the grits are assembled in the form of a large number of columns 32 anchored in a generally upright position relatively to the substrate, the columns having upper portions which are spaced from each other so that the columns form a large number of individual cutters, the spaces 34 between the cutters being generally open and devoid of matrix material. The abrasive tool may be a honing stick, Fig. 5; a honing gear, Fig. 10; a honing wheel with abrasive on the periphery, Fig. 11, or a honing wheel with abrasive on one or both side faces, Fig. 12.

Title: Improvements relating to automatic control systems for water turbines
Inventor: ETTINGER GEORGE MICHAEL
IPC: F03B15/06
Filed: 1956-01-27
Abstract: 839,980. Automatic speed control systems. ENGLISH ELECTRIC CO. Ltd. Jan. 25, 1957 [Jan. 27, 1956], No. 2736/56. Class 38 (4). In a system for controlling the opening of a water gate G of a water turbine WT in accordance with a variable quantity, e.g. speed power output, or water head, the opening of the gate is limited to a predetermined desirable maximum by the change of polarity when an electrical signal dependent on the position of the gate exceeds a similar signal indicative of the desired maximum gate opening. The gate G is controlled in accordance with the speed of the turbine by a tachometer generator S controlling through equipment EG a servomotor SM, and limiting is achieved by a wiper, on a potentiometer RV1 across a source B1, which is moved in correspondence with movement of the gate. The gate position indicating potential is applied to a comparison circuit C with a preset limit potential from a potentiometer RV2, and the output from terminal OT applies a signal to oppose gate opening to the control equipment EG, when it (the potential at OT) is negative. Positive signals during normal operation are earthed through a rectifier MR, and the permissible degree of overtravel is determined by resistor RV3. Resistor RV3 may be replaced by a relay with contacts for applying a limiting potential to the control equip - ment, or the gate positioning and maximum indicating signals may be applied to separate windings of a polarized relay.
