Title: Process for the production of chemical fertilizer
IPC: C05B11/08
Filed: 1929-07-30
Abstract: 332,750. Holz, A., and Berdell, T. van D. July 30, 1929. Manures. - A fertilizer containing dicalcium phosphate is produced by treating crude phosphate or materials containing tricalcium phosphate with sulphuric acid, separating calcium sulphate from the solution of phosphoric acid so formed, and converting the former by means of ammonium carbonate, or ammonia and carbon dioxide, preferably with a slight increase of temperature and pressure, thereby producing calcium carbonate and ammonium sulphate. Potassium carbonate may replace ammonium carbonate, or a mixture of both may be used. A portion, for instance, a third of the calcium carbonate, with calcium hydroxide, is added to the phosphoric acid to form dicalcium phosphate. Carbon dioxide evolved may be employed in the conversion of the calcium sulphate. The solution of ammonium or potassium sulphate is added to the separated dicalcium phosphate, and the whole evaporated to dryness.

Title: Improvements relating to machine tools especially metal sawing machines
Inventor: ROBERTSON ROBERT PEACOCK
IPC: B23D47/10
Filed: 1952-09-26
Abstract: 768,121. Sawing. CLIFTON & BAIRD, Ltd. July 26, 1954 [Sept. 26, 1952], No. 24167/52. Class 145 A machine tool, such as a saw, has.a vice 8 which is closed to grip the work piece 10, is then fed up to a fixed stop to position the work piece beneath a saw 5 on a reciprocable head 3 and, after the cutting operation, is opened to release the workpiece and is then withdrawn against a stop adjusted 'to a position that determines the lengths into which the workpiece is cut. The vice is operated by a pair of concentric pistons 12, 15 reciprocable within a cylinder 11, the rod of the primary piston 12 being rigidly secured to the vice at 14 and the rod of the secondary piston 15 sliding in a bore in the primary piston rod and having a rack 16 engaging a pinion 17 loosely mounted on a cross-shaft 18 on the vice. From the ends of the shaft, gears 18A rotate screws 20 engaging in nuts 21 in the vice jaws 9. The jaws are initially pre-set according to the thickness of the workpiece by means of a handwheel 22, after disengaging a dog clutch 19 by axial movement of the shaft 18, and then oil from a pump is admitted through a pipe A to move the piston 15 and rotate the shaft 18 until the jaws grip the workpiece. As the pinion 17 can then no longer rotate, the vice is moved bodily up to the fixed stop, when the consequent rise in pressure behind the piston 15 operates a valve that delivers oil for lowering the saw head. At the end of the downward stroke, a tappet 6 strikes a lever 3C to change over the valve for the upward stroke, at the end of which a tappet 7 restores the valve to neutral position. Oil from a second pump then flows through a pipe B to force the pistons 12 and 15 apart, thus opening the jaws 9; when the rack 16 engages the end of the rod of piston 12, a valve is actuated to allow oil from the second pump to flow through a pipe C to return the piston 12 and vice 8 to initial position. Pipe B is connected to the annular space between the two pistons by a pipe 15B secured to the cylinder head 11A and by a bore 15D and ports 23 in the rod of piston 15, the piston 12 being cut away at 12A to ensure that, even when the pistons are in contact, the ports 23 will be open. A weight 4 counterbalances the saw head and driving motor 3B.
