Title: Improvements in sintered hard compositions
IPC: C22C32/00
Filed: 1955-04-25
Abstract: A sintered hard composition consists of 15-20 per cent by weight of chromium and the remainder titanium suboxides having a Ti/O atomic ratio of 0.68-1.35.  The suboxide preferably approximates TiO in composition and may be made by mixing titanium and titanium dioxide powders in the appropriate proportions, briquetting and reacting at 1100-1400 DEG C. in a hydrogen atmosphere. The suboxide is then milled and mixed with chromium powder and the composition pressed and sintered (see Group XXII).  Up to 1 per cent iron and some carbon may be present in the composition as impurities.  The composition may be used for cutting tools, extrusion and drawing dies, aircraft components and furnace parts.

Title: Improvements in processes of manufacturing cement, mortars and concretes
IPC: C04B28/08
Filed: 1934-04-23
Abstract: In making cement mortar or concrete, caustic soda or caustic potash is added to pulverized slag to the extent of 5 to 8 per cent or 7 to 11 per cent respectively calculated on the gauging water.  It may be added in solution in the water or as equimolecular proportions of mutually reacting bodies such as sodium carbonate and calcium hydroxide.  These bodies, of which ten-sevenths of the theoretical amount are used, so as to compensate for the incompleteness of the reaction, may be added dry to the slag or to the gauging water from which the resulting carbonate may be filtered.  There may be added gypsum as a retarder and sodium silicate and calcium fluoride.  In examples, (1) a mortar is made by mixing 750 gr. of sand and 250 gr. of ground slag with 103 c.c. of a 6 per cent solution of caustic soda; (2) a concrete is made by mixing as aggregate 1200 litres of air-cooled slag with a mortar consisting of 400 kg. of finely ground slag, 15 kg. of hydrated lime, 21 kg. of anhydrous sodium carbonate and 162 litres of water.

Abstract: 494,405. Cleaning grain. MENEUX, C., BOURDIN, S. G., and CHAUSSE, L. April 25, 1938, No. 12283. [Class 58] Wild garlic or similar impurities are separated from cereal grain by feeding the mixture of hulled and partly ground grain and garlic on to distributing rolls 2, 3, spaced slightly apart and rotating in the same direction over a trough 4 so that the material passes in the form of a sheet between one or more pairs of rollers 7, 8, rotating in opposite directions preferably at slightly different angular speeds. The roller 8 is provided with grooves 9 and flutes 10, as shown in Fig. 2, by which the garlic seeds are picked out from the meal, these seeds being removed from the grooves and flutes by a slowly rotating brush 12 having piassaba or goose feather bristles. The other roller also may be provided with grooves and flutes. The meal, freed from garlic, passes to grinding cylinders 23, 24 and then to bolting devices. The garlic seeds with some bran and meal fall from the brush 12, which engages a stationary brush 13, and are conveyed to a hopper 18 leading to a separating device by which the garlic seeds are finally removed, the bran and the meal passing by the routes 21, 22 to the flour on its path to the bolting devices.

The free-piston type dispenser of Specification 901,850 has piston-operated latches 22, 26 at each end of the cylinder to prevent reversal of the control valves until the piston 11 has made a full stroke in either direction. At the upper end of the cylinder, the latch comprises a member 22 which is guided by a pair of shoulders 29 and is connected to a spring- loaded plunger 23 extending through a seal into the cylinder. The valves 12, 13 interconnected by the central liquid supply tube 16 are arranged to open when the operating handle 17 has reached a position about midway through its arc of movement of 90 degrees and in this position the member 22 drops into a recess 21 extending angularly for about 45 degrees round the boss 20 of the operating handle, thus preventing the handle from being returned to its original position until the piston 11 engages the plunger 23 and releases the latch. A similar plunger 28 and a latch member 26 engaging a recess 27 in the valve 13 are provided at the lower end of the apparatus. A guard may be provided over the upper latch 22.  According to the Provisional Specification, the latch may be a leaf-spring bearing on the plunger.

Abstract: 136,758. Coles, W. J., and Allen & Co., E. May 19, 1919. Stationary batch-mixers with rotary stirrers.-In a machine for agitating cement slurry, crushed ore, or other more or less finely divided material in suspension in a liquid, one or more jets of gas are employed in combination with a mechanically-actuated stirrer. The distributing system for the gas is carried by, and rotates with, the stirrer and is not readily detachable from the stirrer. The tank a is of metal, brickwork, &c., and the stirrers consist of a rectangular framework f of channeiled members mounted on, and rotated by, vertical spindles b. The device for supplying compressed air or gas consists of tubes l open at their lower ends and supplied with gas from a main supply pipe m. The tubes l are clipped to the frame f in order that they may be easily removed for inspection or renewal. It is stated that the gas issuing from the lower ends of the tubes b agitates the material settled at the bottom of the tank, thus reducing the resistance offered by such material to the rotation of the stirrers.

Abstract: 247,440. Western Electric Co., Ltd., (Western Electric Co., Inc.). May 18, 1925. Vacuum tubes.-A valve having an equipotential cathode, which is rendered active by heat radiated from a heating element, is provided with a source of potential for polarizing the cathode with respect to the heating element, so that the cathode screens the other electrodes from an electron stream emitted from the heating element. The arrangement shown in the Figure comprises a valve 2 in which the cathode 5 is heated by an element 6, current being supplied to the element 6 bv a transformer 12 connected to alternating-current mains. The cathode is connected with the mid point of the secondary winding 14 of the transformer, a polarizing battery 15 being included in the circuit. The negative pole of the battery is connected to the cathode. so that the cathode is negative with respect to the heater 6. Electrons emitted from the heater are repelled by the cathode and are prevented from escaping to the grid and anode. In another arrangement, the cathode is connected to the positive pole of the battery 15. With this arrangement, electrons emitted from the heater are attracted to the cathode and do not reach the grid or anode.
