Title: Method and apparatus for adaptively controlling the feed speed of a machine tool
IPC: B23Q15/013
Filed: 1975-05-01
Abstract: 1512663 Machine tool control M POSSATI [Trading as FINIKE ITALIANA MARPOSS SAS DI MARIO POSSATI & C] 1 May 1975 [9 May 1974] 18272/75 Heading G2-3 The feed speed of a machine tool, e.g. a grinder, is controlled in dependence on the deflections suffered during machining by the workpiece and tool. Rings 3 are rotated by a spindle and ground by wheel 6 movable by a stepping motor. The ring is measured by electronic gauge 11, with movable arms 12, 13, connected to detector 14 giving an  analogue output proportional to the difference between the actual ring diameter and the desired diameter at the end of machining. When this output is zero, counter 23 is set to zero, the motor withdraws the wheel 6, the gauge 11 is withdrawn on a carriage (not shown), the machined ring is withdrawn and replaced by a fresh ring. Counter 23 controls the wheel 6 position and, when the wheel moves towards the ring 3, contact 16 is closed on terminal 35, and counter 23 output is converted in unit 31 to analogue which indicates the approx. movement to be made by the wheel to remove all the desired stock from the ring. As the counter is set to zero when reaching the final ring diameter and slide 7 is brought back for a fixed length, the wheel wear is compensated. Before the wheel contacts the ring, the difference between unit 33 output and the initial ring diameter measured by gauge 11 indicates the distance between them and this is fed to program unit 18 which controls slide 7 (and hence wheel) speed. When detector 14 output indicates machining has finished, comparator 46 excites winding 45 and closes switch 43. The output of differential amplifier 39 represents the deflections of the knenatic chain comprising ring 3 and grinding wheel 6. Thus when overstrain is detected, slide 7 feedrate is slowed down. Unit 55 is a dressing unit of known construction.

Title: Purification of phosphoric acid
IPC: C01B25/234
Filed: 1963-05-09
Abstract: Phosphoric acid is extracted from an aqueous solution thereof, especially wet-process phosphoric acid, by contacting the solution with a mixture of a minor proportion of a water-soluble amine, preferably from 5 to 20% by weight, and a major proportion of an aliphatic alcohol having from 4 to 12 carbon atoms per molecule. After contact, the alcohol-amine phase may be separated with the major portion of the phosphoric acid solubilized therein, and the purified phosphoric acid may be recovered therefrom. The alcohols used may have straight or branched hydrocarbon chains, and they may be primary, secondary or tertiary alcohols.  Specified alcohols are n-butanol, secondary butyl alcohol, amyl alcohol, n-hexanol, 1,1-dimethyl hexanol, nonanol, decanol, and dodecanol.  The amines used must be of sufficiently high molecular weight to be essentially water-insoluble, and may be primary, secondary or tertiary amines, preferably secondary or tertiary amines having 10 to 36 carbon atoms per molecule, or primary amines having at least 14 carbon atoms per molecule. Specified amines are octadecylamine, methyl dioctylamine, dinonylamine, dilaurylbutyl amine, trilaurylamine and trinonylamine. Contact may be effected batchwise or by a continuous countercurrent extraction method. If phosphoric acid is the required end-product, the organic mixture may be treated by back extraction with water.  If phosphates are the desired end-product, the organic mixture may be heated directly with the required base, e.g. ammonia, caustic soda, caustic potash, lime, or with a salt whose anion is more easily removed from the solution than is the phosphate, e.g. carbonate or bicarbonate. The base may be added with or without water.  In the latter case, the salt separates as crystals and may be filtered off; in the former case, an aqueous solution or slurry of the salt settles out, and may be separated by decantation, and concentration by crystallization.  The precipitation of any metallic impurities in the aqueous phosphoric acid solution may be prevented by the addition of a sequestering agent.  Agents specified are polycarboxylic, hydroxy-carboxylic and amino-carboxylic acids, polyamines and polyphosphates. The sequestering agent may be added in amount between 0.1% and 5% by weight of the aqueous acid.
