Title: Improvements in or relating to dynamo electric generators for electric welding and for the production of low frequency alternating currents
IPC: H02K23/02
Filed: 1922-09-30
Abstract: 194,634. MacFarlane Engineering Co., Ltd., MacFarlane, J. C., and MacFarlane, W. A. Sept. 30, 1922. Exciting. - A shunt or lightly compounded dynamo for electric are welding or for producing alternating-currents cf low frequency is connected in series with the primary F of a transformer the secondary winding G of which is arranged to react on the field circuit so that a rise of current in the main circuit tends to reduce the main flux. The secondary reaction is adjusted in a welding set so that it cannot completely overcome the main field with strong changes of primary current, but for the production of alternating current the secondary reaction is adjusted to reverse the dynamo field. The secondary winding G of the transformer mav be, connected in series with the shunt winding B, or it may be connected to a separate field winding. In order that the voltage of the dynamo may pick up quickly after a short-circuit, the dynamo may be provided with a few turns of a series winding, or the brushes may be rocked back from the neutral position.

Abstract: 992,090. Counting-apparatus. SODECO SOC. DES COMPTEURS DE GENEVE. July 3, 1963 [Aug. 24, 1962], No. 26414/63. Heading G4D. Resetting mechanism comprises heart-striking levers 2 pivoted on a shaft 8 carrying the numberwheel driving pinions 9, the shaft 8 being movable in a slot 15. Depression of a resetting pin 35 rocks the levers 2 against the action of spring 17 until the ends engage heart cams 31, Fig. 2. Continued movement of pin 35 depresses shaft 8 to disengage pinions 9 from the counter wheels, the levers 2 now driving the counter wheels to home position. Release of pin 35 permits spring 17 to re-engage pinions 9 with the counter wheels before the levers 2 disengage from the heart cams.

Title: Purification of phosophoric acid by means of organic solvents
IPC: B01D11/04
Filed: 1974-06-14
Abstract: 1463742 Phosphoric acid purification HOECHST AG 14 June 1974 [4 July 1973] 26472/74 Heading C1A Impure aqueous phosphoric acid is purified by mixing with an organic solvent in which it is soluble and which is immiscible or partially miscible with water, in a ratio by volume in the range 1 : 0À3 to 1 : 30; the solvent has a boiling point higher than that of water if no water/ solvent azeotrope is formed or if an azeotrope is formed higher than that of the resulting water/  solvent azeotrope and the phosphoric acid/ solvent mixture is heated to a temperature between the boiling point of water or of the azeotrope and that of the solvent to distil off the water present in the phosphoric acid/solvent solution followed by separation of the solid residue and the resulting anhydrous phosphoric acid/organic solvent mixture and recovery of the purified phosphoric acid in the form of the free acid or its salts. Preferably crude phosphoric acid from conduit 1 is admixed with scrubbed raffinate (recycled through conduit 17) and sulphuric acid (from conduit 2) is mixed with circulated solvent in a reactor A. A sodium compound, for example sulphate, hydroxide, phosphate or carbonate, is added through conduit 3 and a 20 wt. per cent solution of Na 2 S and active carbon are added from conduits 4 and 5 to effect precipitation of heavy metals and adsorb organic impurities. Pure water or azeotrope distils over at 10 and is cooled in condenser D or if an azeotrope separated into its components in a separator E. In the latter case the solvent is recycled through conduit 12 into the reactor A whereas the aqueous phase by way of conduits 13, 14 and 15 is used partially for scrubbing the organic solvent/phosphoric acid solution in B and partially for the reextraction of phosphoric acid in C by a multistage counter-flow scrubbing operation. The solvent by way of conduit 16, is recycled to the reactor A. Scrubbed raffinate, flowing through conduit 17 is recycled to A and extracted anew with solvent. Useful solvents include organic substances which are immiscible or partially miscible with water e.g. butanol, amyl alcohol, ethylhexanol, dibutylether, methylisobutyl ketone, butyl acetate or tributyl phosphate.

Abstract: 479,151. Receiving - devices for bottles. BRIERLEY, A. W., DUNKERLEY, N., and HUNTER, J. Sept. 30, 1936, No. 26546. [Class 18] A receptacle into which bottles can be delivered has an opening 1a in one side through which the bottle is inserted and its top is so restricted by chamfered bars lb and a rod 9 that, while the contents of the bottle is accessible, the bottle cannot be withdrawn through the top. The receptacle is hinged at 2 to brackets 3 and the contents of the bottle can be poured out by tilting the receptacle to the position 1d as shown, the receptacle is secured behind an aperture in a house door 4, and the opening 1a can be closed by a door 5 with a lock 6 sliding in vertical grooves in the sides of the receptacle. A further groove 1a<1> and a removable cover 8 is provided in case there should be a beading above the door 5. A spring catch 11 holds the receptacle in its upright position. An aperture 1c allows the fingers to be inserted to facilitate withdrawal or insertion of a bottle. To retain a small bottle, a yoke 13 is swung up and held horizontally by spring 14 or an apertured plate is slid into horizontal grooves in the of the receptacle. To house more than one bottle two receptacles are pivoted on a platform slidable along the pivot rod 2 so that either receptacle can be brought opposite the aperture in the door, but when a receptable is not opposite the aperture, a dovetail bar on its underside engages in a similar groove'on the bracket to prevent it from being tilted.

Abstract: 504,889. Making welded tubes. NEUNKIRCHER EISEINWERK AKT.-GES. Sept. 13, 1938, No. 26691. Convention date, Nov. 13, 1937. [Classes 83 (ii) and 83 (iv)] Welding; angular heating.- In making longitudinally jointed tubes from band iron by electric welding, the contact surfaces of the band are freed from scale while hot, prior to welding, by a cutting or scraping apparatus. A metal strip 1 is fed by rolls 6, 7, first through sectioning rolls 9-15, then under a gas burner 17, then under a screw-adjusted scraper 24 of alloy steel or metal carbide, which removes scale from the upper surfaces in the vicinity of the joint, then through guide rolls 27 and electric welding rolls 28, 29, 31, and then through finishing tools 34, 34<1>. The burner and scraper may be applied to the strip before conversion into tubular form. The scraper may be in the form of a knife or may be formed with teeth, which may be at different heights. In another form, Fig. 3, the tool 35 may have also a projection 36 for cleaning the abutting edges of the tube. In a further form, Fig. 8, adjustable spring-pressed tools 47 may be arranged to engage opposite edges of die strip, a pair of scrapers being also arranged underneath to clean the surfaces which are to form the upper contact surfaces. The edges and upper surfaces may also be cleaned by two pairs of milling cutters 62, 64, Fig. 9, immediately after the strip has passed the final rolls 51, 52 of a rolling mill so that no supplementary heating is required. Instead of milling cutters a bar 67, Fig. 13, with fixed scrapers 62b may be provided. Spring-pressed milling cutters (66, Fig. 12, arranged on inclined axis or similarly arranged V-shaped stationary cutters may also be used. Emery wheels may be used.
