IPC: B23B31/12
Abstract: 113,574. Halstead, J. F. Aug. 29, 1917. Chucks.-In chucks disengageable while in motion, the jaws are supported in a body normally rotating with the shank, relative motion between the body and shank being produced by means comprising clutch mechanism in order to operate the jaws to release the tool. The screwed end 11 of the shank 10 engages a body-part 15 secured to a tapered casing 17 in which slide spring-separated jaws 19 engaged by a disk 14 with a stem 13 sliding in the shank-end. Slidably secured to the shank by rollers 30 is a pinion 27 gearing through connected pinions 26, 24 with a loose pinion 22 carrying clutch dogs 23 engageable with clutch dogs 21 on the part 15. The spindles 25 of the pinions 26, 24 are carried by a housing 31 and an outer sleeve 33. The housing 31 and part 15 are normally separated by a spring-pressed plunger 34, the action of which is limited by a stop 39, engaging recesses in the plunger and the sleeve 33 and itself locked in position by a stud with an eccentric head 42. To clamp the tool, the casing 17 is held by hand and the part 15 screws back on the shank so that the tapered casing 17 presses the jaws 19 on the tool. To disengage, the sleeve 33 is pressed down to engage the clutch 21, 23 and at the same time held to keep the gearspindles 25 stationary. The gearing is proportioned to accelerate the body-part 15, which screws towards the end of the shank and releases the jaws. To dismantle the chuck, the casing 17 is first removed and the stud 41 is turned to withdraw the stop 39 from the sleeve 33 so that the sleeve may be moved to allow removal of the stud 41, stop 39, and plunger 34 and, afterwards, of the part 15.

[Class 40 (i)] [Also in Group XIX] An electric transmission dynamometer in which the torque of a shaft is measured by mounting a pair of alternators along the shaft, the outputs being of the same frequency and in phase when the shaft is rotating with no torque, is characterized by means for measuring directly by a phase meter, the phase angle between the output voltages of the alternators, whereby to indicate the torque transmitted independently of relative variation in the output voltage of the alternators at different speeds. As shown, a single phase alternator A is connected through an inductance LA to the stationary coil of a power-factor meter, while the two phases of a multi-phase alternator B are connected to the moving coils through inductances LB. At no torque, one of the instrument coils aligns itself with the stationary coil : the angle of instrument deflection is proportional to the angle of twist of the shaft.

Title: The recovery of cadmium catalyst from residues obtained in the manufacture of aromatic dicarboxylic acids
IPC: C07C51/41
Filed: 1957-04-10
Abstract: In a process for the manufacture of a salt of an aromatic dicarboxylic acid, particularly terephthalic acid, wherein a monovalent metal salt of another carboxylic acid is heated in the presence of a cadmium catalyst and the reaction-product is extracted with water, the water-insoluble residue is treated with nitric acid whereby the cadmium is dissolved out from the organic impurities. The cadmium is then recovered from the acidic extract and may be reused in the process.  Suitable catalysts are metallic cadmium, and cadmium oxide, iodide, chloride, fluoride, sulphate, phosphate, carbonate, acetate, benzoate, phthalate, isophthalate, terephthalate and stearate.  In the case of terephthalic acid the starting material may be an alkali or thallium salt of a benzene carboxylic acid having from 1 to 6 carboxyl groups.  In an example, potassium benzoate was mixed with about 2.4% of cadmium chloride in a pebble mill; and the mixture was then heated at 440 DEG  C. for 1 hour in a stainless-steel vessel in an atmosphere of carbon dioxide at a pressure of 150 p.s.i. Benzene vapour was bled-off during the reaction.  The product was boiled with water, and the resulting solution was filtered.  The filtrate was acidified with hydrochloric acid to precipitate terephthalic acid.  The insoluble residue remaining in the filter was collected and dried.  It contained substantially all the cadmium present in the initial mixture predominantly in the form of cadmium carbonate.  This residue was treated with excess of 20% aqueous nitric acid at about 100 DEG  C. The mixture was filtered, and aqueous sodium carbonate was added to the filtrate.  The cadmium carbonate, obtained by further filtration, corresponded to 98.7% of the cadmium present in the initial mixture. Specifications 744,721, 747,204, 762,448, 762,644, 777,497, 777,609 and 819,281 are referred to.

I1, I3, I5, &c. have no individual feed and discharge pipes, a common header being formed by a hole in each of the frames at opposite diagonals for feed and discharge, with a passage therefrom to cells I1, I3, I5, &c. only. The pure lye cells have individual pipes as before.

Title: Electrodeposition of polymers in porous electrodes
IPC: H01M4/86
Filed: 1961-04-04
Abstract: <PICT:0939823/III/1> A porous fuel cell electrode, e.g. carbon impregnated with a catalyst for use as anode or cathode, is coated internally with a thin film of a high molecular polymer by electrodeposition from an aqueous dispersion of the polymer.  The larger pores in the carbon i.e. exceeding 8 X 103A are thereby coated, and flooding of the electrode with electrolyte is prevented. The polymer used is preferably a fluorine-containing compound, e.g. P.T.F.E. or P.V.F., or copolymers of tetra-fluoro-ethylene and hexa-fluoro-propylene, which are dispersed with a wetting agent forming particles of size about 1 X 103A, and are deposited on the internal surface of a hollow carbon electrode, electro-phoretically. Other film-forming polymers may be dispersed with the F-containing polymer, e.g. polyisobutylene or butyl rubber.  For example, a porous hollow carbon electrode of the kind described in Specification 900,451 is impregnated with a catalyst, e.g. metals, oxides, or sulphides of Ag, Au, Pt, Mn, W, Pd, Rh, Ir, Co, Ni or V, or compounds e.g. Co molybdate, and is then mounted at 47 within a wire screen 46, submerged in the aqueous dispersion 48 of the polymer.  The hollow carbon electrode is connected through a pipe 45 to an exhaust pump which draws the dispersion inside the electrode, on which the polymer is then deposited by applying 3 to 30 V at a current of 0,1 to 1 amp. for up to 1 minute.  The coated electrode is then purged with gas, and dried at 200 DEG F., and finally heated at 600 DEG  to 750 DEG F. in nitrogen, until incipient decomposition of the polymer commences to effect sintering.  Tables are given of electrode performance with and without the coating.  Specifications 797,001, 900,451 and 918,172 are referred to.
