Title: Improvements in the Manufacture of Compounds of Alumina.
Filed: 1902-11-22
Granted: 1903-09-24
Abstract: 25,683. Spence, H., and Spence & Sons, P. Nov. 22. Ammonia alum; aluminium sulphate.-Consists in producing a highly-basic aluminium sulphate, soluble in hot and cold water, along with ammoniaalum, from normal aluminium sulphate. Ammonia is passed into a hot solution of the normal sulphate in sufficient quantity to combine with part of the sulphuric acid, about one sixth, of the sulphate, and thus form ammonia-alum along with part of the unacted-upon sulphate, leaving the remaining sulphate as the basic compound, according to the equation- A larger proportion of basic sulphate is obtained with a proportionately smaller amount of ammonia by using a sulphate solution containing an excess of alumina. On cooling, the alum crystallizes out from the basic sulphate solution, which is then concentrated, preferably under reduced pressure, to a s.g. 1À45 at about 70‹ C., and the sulphate crystallizes out on cooling, the operation being assisted by agitation. If a magma forms before the crystals, it will be converted into crystals on stirring. It is usually advantageous to use less ammonia than is required for one-sixth of the sulphuric acid, say enough for one-seventh, so as to leave a little normal sulphate in solution, as the basic sulphate separates readily from solutions containing normal sulphate owing to its comparative insolubility in them. The same result is attained by having enough free acid in the original normal sulphate solution to leave the desired amount of neutral normal sulphate in the final liquors. The crystallized basic sulphate may be purified by re-crystallization, preferably from a solution which contains a proportion of normal sulphate, or the basic sulphate solution may be evaporated in the first place so as to set in a solid cake on cooling. The crystals may be dried and part of the water of crystallization driven off, obtaining a product with a still higher percentage of alumina. In the Provisional Specification, it is stated that soda or potash may be used instead of ammonia, but the resulting soda-alum is not readily separated, since its solubility is very near that of the basic aluminium sulphate.

Title: Improvements in and relating to Fluid Pressure Impact Tools.
Inventor: GREEN CARL RICHARD
Filed: 1902-12-04
Granted: 1903-02-12
Abstract: 26,807. Green, C. R., and Hayes, G. H. Dec. 4. Percussive hand tools.-Fig. 1 shows a section of the tool adapted for riveting, Fig. 2 shows a section of the valve-chamber with the valve in its forward position, and Fig. 3 shows a section of the valvechamber taken on a different plane to that of Figs. 1 and 2. Compressed air or other motive fluid is admitted to the valve-chamber by pressing the trigger 23 so as to open the throttle valve 22. Accidental starting of the tool is prevented by a grooved spring-actuated pin 25 which must be pressed aside before the trigger can be depressed. The space 9 is always in communication with the motive fluid through the channel 21, and the space 30 is always in communication with the exhaust through channels 15, space 16, and opening 17. During the forward movement of the piston 4, air enters the rear of the cylinder through the opening 31, and the exhaust is effected through channels 100, 10, and 33. The valve 7 is next moved forwards into the position shown in Fig. 2 by the air cushioned in front of the piston after it has passed the opening to the channel 100. This cushioned air passes along the channel 120, and is supplemented by live air which enters this channel by the opening 24 now behind the piston. Compressed air thus passes to the channels 12, 19, and acts on the rear face or piston of the valve. This face being larger than the front face, the valve moves forwards. During the rear movement of the piston 4, air enters the front of the cylinder through the small channel 18, and channels 19,12,120, and the exhaust is effected through the channels 110,11,34. The valve is driven back to its initial position by the air cushioned at the rear of the piston 4. The valve is so arranged that live air is always pressing on one of its heads so as to steady it. It is stated that air leaking past these heads does not interfere with the working of the tool. The walls of the cylinder contain five channels similar to the channel 100 and two similar to the channel 110, and the channels 15 are similarly multiplied.
