A combine-harvester is provided, in place of the conventional straw-walkers, with a separating apparatus comprising an openwork endless conveyer 30 having an upper run which travels rearwardly at a speed considerably below the peripheral speed of the threshing drum 20 and receives the mat of straw discharged by the later slowing down its progress so that grain may separate out owing to its greater inertia, the conveyer being followed by means 34 for increasing the linear speed of the mat to thin it out, thereby permitting grain to pass through it. The process is repeated by a second endless conveyer 44 followed by an accelerating means 46, the mat being finally slowed down again by an endless conveyer 54. The accelerating means 34, 46 comprise tined drums rotating above openwork grids 40, 50. The peripheral speed of the concave is 3500- 7000 ft./min. and that of the conveyer 30 is 150-200 ft., the peripheral speeds of the drums 34, 44 being approximately 5 times the latter figure.

Title: Article having a radially varying composition
IPC: C03B37/027
Filed: 1973-03-30
Abstract: 1416387 Light focusing fibre waveguides CORNING GLASS WORKS 30 March 1973 [30 March 1972] 15431/73 Heading C1M [Also in Divisions G2-G3] A method of forming an article having a radially varying composition such as light focusing fibre waveguides comprises applying a plurality of layers of glass to a cylindrical member, each successive layer having an incrementally different composition as compared with the composition of the preceding layer, heating the structure so formed to the drawing temperature and drawing the heated structure to reduce the cross-sectional area thereof to form an article having a radially varying composition. Each layer may be formed from fused silica doped with a different quantity or kind of material. Suitable dopants are TiO 2 , Ta 2 O 5 , tin oxide, Nb 2 O 5 , ZrO 2 , Al 2 O 3 , La 2 O 3  and GeO 2 . The maximum amount of dopant is preferably below 25% by weight of the composition at that point. The layers may be applied by brushing, spraying or dipping a mixture of glass materials suspended in an organic resin vehicle, e.g. a mixture of titanium resinate solution containing 4À2% by weight Ti and silicon resinate solution containing 7% by weight Si; by chemical vapour deposition ; by radio frequency sputtering or by applying a glass frit and sintering the frit. The cylindrical member may be of glass having a coefficient of expansion compatible with the layers to be applied or graphite. In one embodiment, Fig. 2, a gas-vapour mixture is hydrolysed within flame 16 to form a glass soot 20 which is directed on to a rotated glass cylinder. The gasvapour mixture is changed for each successive layer 10. The soot may be sintered as deposited or it may thereafter be sintered. The cylindrical member may be ground out by means of a diamond reamer, laser milling, etching with hydrofluoric acid, or by core drilling. The resulting hollow body is then drawn to form a film of sold cross-section. If the cylindrical member is not removed from the structure the resulting structure may nevertheless be drawn, except no longitudinal hole will be collapsed. Alternatively the layers of incrementally different composition are applied to the internal surface of a hollow surface, e.g. by the flame hydrolysis technique. Each layer may be about 0À0175 inch in thickness and composite structures having up to 60 such layers may be produced. The plurality of layers of glass soot may be sintered in an induction furnace having an oxygen atmosphere at 1500 C. prior to drawing. The drawing may also be carried out in an induction furnace containing oxygen, at a temperature of 2000 C. Specific compositions of the glass layers disclosed are (a) a glass consisting of 99À993% by weight SiO 2  and 0À007% by weight TiO 2  and (b) a glass consisting of 97% by weight SiO 2  and 3% by weight TiO 2 .

Title: Improvements in and relating to mechanical printing processes
IPC: B41F9/04
Filed: 1929-05-22
Abstract: 334,183. Beaune, S. May 22, 1929. Inking-apparatus. - In multi-colour printing from a single engraved plate or cylinder, the inks are applied to the printing-surface by a number of inking-rollers having relief surfaces corresponding to the areas of the different colours to be applied, and the surplus colours are removed by a wiping-roller from which the colours are continuously removed. The inking-rollers are provided with an elastic and easily cut coating, e.g. of wax, whitening, gelatine, and glycerine, and are of a circumference equal to the length of the design to be printed. In preparing the rollers for inking, they are placed in the machine and an inked impression from the printing-surface is applied to each roller. The surface of each roller is then cut away to leave in relief only that portion corresponding to the colour which the roller is required to apply. Each inking-roller is supplied with colour from a fountain Q, Fig. 3, by a steel roller P having a milled surface, a steel blade S removing all colour except. that in the recesses of the roller. The wiping-roller is provided with a coating of a composition similar to that of the inking-rollers and is rinsed with alcohol, after which it is rotated in a bath of a saturated solution of alum. After drying it is maintained at a temperature of about 3‹ C. for at least 24 hours and is then rubbed with chamois leather. It is mounted in the machine and driven so that, during the wiping operation, its surface moves at the same speed as the printing-surface but in the opposite direction. To clean the roller after the wiping operation, its surface may pass in succession under a reciprocating brush B, Fig. 6, supplied with a solvent such as carbon tetrachloride, a rubber blade Z, and a steel blade Y which conveys the removed colour into a container N. The roller may be surmounted by a bell-shaped casing provided with a suction device. An alternative method of cleaning the roller consists in causing it to rotate in a bath O, Fig. 7, of solvent in which are mounted reciprocating brushes U rotated in a direction opposite to that of the wiping-roller D. A rubber blade Z removes. the solvent and colour.
