Abstract: 1344869 Spherodizing ceramic material COORS PORCELAIN CO 18 June 1971 28648/71 Heading B5A [Also in Division C1] Small ceramic spheres are made by forming a bed of powdered, preferably non-hydroscopic material, e.g. wax or alumina, on a work surface; discharging drops of ceramic slip on to the surface of the bed to form spheres; reforming the bed surface, e.g. by inverting it, and discharging further drops of ceramic slip to form more spheres. The powder is deposited from a hopper 42 on to a moving conveyer belt 34 and levelled off by a bar 46. Dry ceramic material such as alumina is fed to a ball mill 14 then milled with water in a wet ball mill 18 and passed to a holding tank 20 together with an agent such as magnesium sulphate where it is agitated to maintain it in suspension. The slurry is discharged through a first set of nozzles 30 which are set at an angle across the surface of the bed to deposit drops in staggered array. A radiant heater 50 dries the drops and the moving bed then rides up a ramp 52 and drops over the end so that the ceramic spheres fall on to the bottom and the powder forms into a bed over them. A second set of nozzles 32 and radiant heater 58 deposit and dry a second layer of ceramic spheres, the material then discharging on to a separator 60, the powder being returned to the hopper and the ceramic spheres taken through a set of sizing screens 62 and fired in a kiln. The ramp 52 (Fig. 2, not shown) comprises an adjustably inclined blade set across the belt surface and followed by a doctoring bar. The set of nozzles may be formed by inserting hollow needles through the wall of a plastics tube, inlet and return conduits being provided thereto (Figs. 3 and 4, not shown). Specification 1,344,870 is referred to.

A poppet valve 15, e.g. containing sodium supported by the extension 18, controls communication between the piston interior and the combustion chamber 5 and opens as the piston 10 approaches B.D.C. to permit gas to flow from the piston interior to the combustion chamber. The valve 15 is opened by the pressure in the piston interior and/or by contact with the extension 18 or by contact of the end (21), provisional drawing, of the valve stem (16) with oil at the bottom of a bore (20) in the extension. The valve 15 may be opened hydraulically, pneumatically or by cams. In the two-stoke engine shown, petrol, lubricant and air mixture is drawn from a carburetter or respective carburetters through a rotary face valve 33 and one or more non-return valves into chambers respectively above and below the pump piston 12 for delivery to cavities 66 in the cylinder head 2 or an annular cavity (30), provisional drawing, in the cylinder head, and the piston interior and combustion chamber 5, respectively. Lubricant is fed through passages 63, 64 in the extension 18 to the rollers 52. Cylinders 1 may be provided at both ends of the shaft 19 and a number of shafts 19 may be geared to an overall output shaft. The locations of the cam followers and cam track may be reversed.

Date Jul. 9, 1992.The invention uses framestores for storing successive parts of three frames from the source of a video signal such as a camera, and a logical output selection unit arbitrates between the outputs for the frame to produce a reduced noise output to be fed to a T.V. monitor. If the noise of a pixel in the central frame is increased significantly compared to that in the first frame, the output of the third frame for that pixel is used to arbitrate between the two, for example, by selecting as the output that of the first frame if it is found that the output of the third frame is nearer to that of the first frame than to the second. Isolated noise specks are thereby reduced without the problems of motion smear.
