Title: Improvements in and relating to Automatic Control of the Cutting Tool position in Multiple Spindle Automatic Lathes
IPC: B23Q15/16
Filed: 1968-02-26
Abstract: 1,198,912. Automatic multi-spindle lathes. WERKZEUGMASCHINENFABRIK GILDEMEISTER & COMP. A.G. 26 Feb., 1968 [2 March, 1967], No. 9244/68. Heading B3T. In a method of controlling the position of a cutting tool in an automatic multispindle lathe in which work-holding spindles 12 are carried in an indexing spindle drum 11, a workpiece machined at a work station II is measured at the next station I in the direction of indexing of the spindle drum and the measured reading compared with a predetermined value by control unit 25, the variation being stored in storage units and which is retrieved to effect control of the cutting rool position in relation to each spindle as it passes through the work station II. In this manner tool wear and the inaccuracies in each spindle is determined separately. In operation measuring means 23 measures the work diameter at the work station I and transmits the measurement to the control unit 25, e.g. a pneumatic device operable by differential pressure, and an error signal is subsequently passed to the storage unit 1 by way of a rotary distributer 26 and which is recalled after a complete indexing cycle of the spindle drum by a further distributer 27. The distributers and the spindle drum are indexable in unison and the measurements of each workpiece in its spindle as it is indexed through the station I is passed from the control unit 25 to the respective storage unit 1 to 6. After the first indexing cycle the error values are recalled in respect of each spindle and the cutting tool position adjusted accordingly by the pneumatic and mechanical actuation of the tool slide. The normal feed and return movements of the tool slide 13 is effected by a rack and sector mechanism 21, 20 driven from the main drive of the machine and the position of the cutting tool adjusted in relation to the slide by a pneumatic control unit 14 which is actuated at each index of the spindle drum in response to the signals received from the respective storage units. The control unit 14 may act directly on the cutting tool as in Fig. 4 (not shown) to effect the compensating adjustment required, or by way of an auxiliary slide, Fig. 5 (not shown), or alternatively by actuation of the rack to cause movement thereof relative to the tool slide as in Fig. 7 (not shown).

Title: Improvements in or relating to cameras for taking multiple photographs
IPC: G03B19/02
Filed: 1935-03-25
Abstract: 454,234. Cameras for taking multiple photographs. ALLDRIDGE, R. S., Ethelridge, College Hill Road, Harrow Weald, Middlesex. March 25, 1935, No. 9276. [Class 98 (i)] The camera comprises a box divided into compartments and the lens is carried by a revolving plate which stops in front of each compartment in succession, means being provided automatically to operate the shutter during each stop. The shutter preferably comprises an apertured disc which is rotated by a spring and held from rotation during the movement of the lens plate. In the form shown, the camera body is divided into 4 sections by internal partitions which extend to the surface of the dark slide. The lens 4 is carried by a plate 2 mounted on a pillar 46, bearing a Maltese-cross 47, the latter being operated by a pin on a disc 45 carried by a spring driven shaft 23. The shutter 34 is carried by a spring driven shaft 37 and is normally held from rotating by a stop on the shutter engaging with a pivoted detent on the pillar 46. When the pin on the disc 45 leaves the slot of the Maltese-cross, a fixed stop engages the detent to release the shutter. The springs for driving the shutter and lens plate are wound by a common knob 41 and the time of exposure may be varied by altering the aperture in the shutter plate or the tension of the driving spring. The plate 2 carries pins 6 engaging a stop which normally holds it against rotation. When it is desired to make fewer exposures than are effected by one complete revolution of the lens plate, a serrated wheel mounted alongside the disc 2 and advanced one step by engagement with each of the pins 6, is adjusted so that a stop on this wheel comes into action after the desired number of exposures.

These latter are defined by refractory material 44 applied in plastic condition and by bricks 49, the material 44 also providing a covering for the header 38, limited expansion being allowed for by packing asbestos between the refractory parts and metal parts of the structure. Modifications are described in. which the two headers are not placed vertically one above the other and a variety of arrangements of the tubes 41 and 42 are disclosed, in one of which, Fig. 24 (not shown), some of the tubes 9 are connected directly to the lower header and the upper header is also supplied directly by some of the downcomers 41 and in another, Fig. 19 (not shown), the downcomer tubes 41 pass through the upper header 11. Under suitable conditions the Bailey blocks and' refractory protection may be dispensed with.

Title: Improvements in or relating to removal of nitric acid from aqueous solutions
Inventor: JAMRACK WILLIAM DOUGLAS
IPC: C01B21/46
Filed: 1955-04-01
Abstract: Effluent aqueous raffinate resulting from the organic solvent extraction of aqueous nitric acid solutions of neutron-irradiated uranium is extracted with an organic solvent in which nitric acid is soluble and the organic solvent solution of nitric acid produced is treated with water to dissolve the nitric acid. Solvents may be dibutyl phosphate, diethylene glycol dibutyl ether, or tributyl phosphate, and the latter may be diluted with a non-polar organic diluent, e.g. kerosene.  The raffinate may be 3N in nitric acid and contains uranium, plutonium, and uranium fission products having b and g  activity, e.g. cesium 137, whose isolation necessitates evaporation, which is difficult in the presence of nitric acid.  An effluent raffinate containing nitric acid, ruthenium, zirconium, and plutonium is subjected to countercurrent extraction, preferably in a 12-stage airlift extractor with the organic solvent, the flow rate of solvent to raffinate being approximately 16: 1.  The organic solvent solution may be subjected to one or more stripping stages, and is then washed with water in countercurrent, the flow rate of water being 1/4 that of the solution.  The washed solvent is returned to reservoirs for reuse.  The extracted raffinate was 0.13 N nitric acid and could be readily evaporated.

Title: Novel amino-propane derivatives and a process for the manufacture thereof
Filed: 1961-03-17
Abstract: The invention comprises 1-(p-biphenyl)-2-aminopropane (I) and acid addition salts thereof, a process for their preparation by catalytically hydrogenating 1-(p-biphenylyl)-2-oxopropane or its oxime in the presence of ammonia, followed by conversion to an acid addition salt if desired, and pharmaceutical preparations containing (I) or an acid addition salt thereof and a carrier. The hydrogenation may be effected in alcoholic solution in the presence of Raney nickel and under pressure.  1-p-Biphenylyl)-2-oxopropane is prepared by treating 4-phenylbenzyl chloride with an alkali metal cyanide to form 4-phenylbenzyl cyanide, reacting the latter with a lower alkyl (e.g. ethyl) acetate in the presence of sodium ethoxide to form sodium 4-phenyl-a -acetylbenzyl cyanide, and acidifying to form 4-phenyl-a -acetylbenzyl cyanide, followed by hydrolysis of the nitrile group and decarboxylation.  1-p-Biphenylyl)-2-hydroxyiminopropane is prepared by (a) condensing biphenyl-4-aldehyde with nitroethane to form 1-(p-biphenylyl)-2-nitropropene-(1), followed by catalytic hydrogenation, or (b) condensing 1-(p-biphenylyl)-2-oxopropane with hydroxylamine hydrochloride in the presence of sodium acetate. Compound (I) and its salts with inorganic and organic acids are useful as anorexic agents in the treatment of obesity, and may be administered enterally or parenterally in the form of pharmaceutical preparations (e.g. tablets, dragees, suppositories, capsules, solutions, emulsions and suspensions) containing the active ingredient and a carrier, with or without other (unspecified) therapeutically useful substances.
