Title: Machines for assembling fasteners with washers
Inventor: NIELSEN MORITZ HERLUF
IPC: B23P19/08
Filed: 1955-11-23
Abstract: 808,317. Assembling nuts and washers. ILLINOIS TOOL WORKS. Nov. 23, 1955, No. 33635/55. Classes 83 (2) and 83 (4). [Also in Group XXX] Jointing by stamping; breaking.-In a machine for assembling washers 76, Fig. 23, on fasteners such as nuts 214 &c., the washers are fed and assembled with the nuts in strip form and are subsequently separated. Spring washers 76, Fig. 2, are fed in a multiple strip 52 which is initially split longitudinally at the transverse connections 80 to form separate strips 58. The separated strips 58 are fed to a swaging mechanism 68, Fig. 1, to which nuts 214, Fig. 20, are supplied from a shoot 66. Each strip 58 passes over a grooved roll 326 having projecting pins 328 engaging in the washer flanges 388 and having frusto-conical head portions 338 which engage skirts 216 on the nuts under the pressure of a co-operating roll 362 to swage the skirts outwards and lock the washers in position. The strip of assembled nuts and washers is finally twisted to break the longitudinal connecting portions 78 and separate the washers completely. The multiple strip 52, Fig. 1, is drawn from a reel 50 by a feed mechanism 54 comprising a disc 96 having two rows of radial fingers 106 engaging in the washer holes and forcing the strip through a tubular guide 117. The feed mechanism is driven through a spring- loaded friction clutch to prevent damage in the event of jamming. The strip is then split longitudinally by a pair of rolls 56 which have frusto-conical engagement faces 128, 146, Fig. 7, to bend the strip at the transverse portions 80. The separation is completed by the sideways pull exerted on the strip by rolls 150 on the ends of arms 152 attached to the frame and carrying mercury switches 158 which stop the machine in the event of the strip breaking or running out. The assembly operation is then carried out in the swaging machine 68, the nuts being fed from a pair of rotary hoppers 60 which supply nuts into a guide tube 62. The nuts are fed into a further guide 66 by means of a selecting mechanism 64 which comprises a wheel 206 having projecting pins 208 to engage in the nuts and force them under a grooved guide-plate 192a, Fig. 8. Nuts which are the wrong way up for the swaging operation are raised in the grooves 272a and engage a deflecting guide track 274a which ejects the nuts into a tube 282 and bin 284 while the remaining nuts pass directly through grooves 254a to the guide 66. In the event of a failure in the supply of nuts a feeler arm 296 operates a switch 286 to stop the machine. On leaving the swaging machine the assembled strip is fed through a guide 408 to a rotary twisting head 414, Fig. 15. The head contains an L-shaped plate 440 which permits entry of the leading end of the strip into the head but has a leg 442, Fig. 29, which engages the leading washer and twists it free of the strip. The finished assembled nuts and washers fall through a guide tube 72 into a bin 74.

Title: Pigment compositions
Inventor: ROBERTS JOHN FRANCIS LLOYD
IPC: C09B67/20
Filed: 1957-10-30
Abstract: A stable pigment dispersion is made by milling together, in the presence of an aqueous liquid, a coloured or fluorescent pigment and a synthetic linear polyester in the form of fine particles. The polyester particles are preferably those of polyethylene terephthalate having a particle size of 5-100 microns and made by the process of Specification 830,372.  The Specifications contain long lists of inorganic and organic pigments and fluorescent pigments and these may be used in admixture with a white pigment (e.g. titanium dioxide) or an extender, (e.g. barium sulphate). The aqueous liquid is preferably just water but may be an aqueous solution of alcohol, acetone or urea.  Dispersion is preferably effected by gravel milling the ingredients followed by sieving to remove the gravel.  The pigment dispersions are especially useful for the mass colouration of linear polyesters or polyamides but may also be used, in the form of an aqueous paste to coat paper, card or textiles.  In examples (1) and (18) an aqueous paste of polyethyleneterephthalate particles is gravel milled with copper phthalocyanine in the presence of water, and after sieving, the dispersion is dried, ground to a fine powder and mixed with polyethylene terephthalate chips which are afterwards melt spun into fibres or injection moulded; (2)-(15) An aqueous paste of polyethylene terephthalate particles is gravel milled in the presence of water with various pigments and the resulting aqueous dispersions mixed with polyethylene terephthalate or polyhexamethylene adipamide chips which are thereafter dried and melt spun; (16) and (17) Aqueous dispersions of polyethylene terephthalate particles and various pigments are mixed with casein size and the compositions brushed on to a card or sprayed or printed on to paper. Specifications 313,094, 436,957, 698,200, 705,928, 797,046, 799,352 and 799,607 also are referred to.

Title: Improvements relating to pulse width modulated inverters
Inventor: O'NEIL WALTER KENNETH
IPC: H02M7/515
Filed: 1962-09-04
Abstract: 1,048,045. Inverting. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 22, 1963 [Sept. 4, 1962], No. 33924/62. Heading H2F. The Specification relates to pulse width modulated inverters having at least one pair of controlled rectifiers, arranged to conduct load current alternately, and reversely connected diodes across the controlled rectifiers. According to the invention a pair of inductively coupled windings are connected, the one in series with the controlled rectifier and the other in series with the corresponding diode. In the Figure, which shows a pulse width modulated inverter with commutating capacitors forming resonant circuits with the inductors, the windings T1PA and T1SA, in series with controlled rectifier SCR1 and diode D11 respectively, are also inductively coupled to windings T1PB and T1SB which are in series with the controlled rectifier SCR2, which conducts alternately with SCR1, and its corresponding reverse diode respectively. The arrangement is such that reverse current flowing in a diode and its associated winding induces in the winding associated with the controlled rectifier a voltage which aids turn off of the controlled rectifier. The load 5 may be a D.C. load, and the effective direct current through it is controlled by varying the mark-space ratio of the inverter.

Abstract: 1424828 Treating aqueous effluent ETUDES ET PROCEDES D'ASSAINISSEMENT PURATOR 17 July 1973 [17 July 1972 29 Nov 1972] 34089/73 Heading C1C Aqueous effluent is treated with either (a) aluminium amalgam, preferably in the form of A1 plates or fragments having a surface layer of amalgam, or (b) alumina hydrate and/or (c) microbubbles of hydrogen, both obtained by reaction of (a) with a separate supply of water. The surface of the Al is amalgamized either before the treatment, by contacting it with mercury or mercuric salts, or during the treatment by immersing the lower parts of vertical Al plates in narrow channels containing mercury at the bottom of the treatment vessel whereby the mercury diffuses upwards to the areas of the plates in contact with the water. Treatment of aqueous effluent with (a) or (c) results in a surface foam containing impurities and, in the case of (a), alumina hydrate, and this foam is removed by scrapers. Treatment with (c) is effected by reacting the amalgamized aluminium with water in a preliminary tank, and mixing the thus-produced gasified water with the aqueous effluent in the main treatment tank or at the inlet thereto. Treatment with (b) alone is effected by adding the alumina hydrate in the form of a dried powder or aqueous sludge, optionally after "ageing", and results in the formation of a sediment from which the treated water is removed. The aqueous effluent may be previously or concurrently treated with unspecified acids or bases, flotation additives (e.g. polyacrylamide), surface active agents (e.g. sulphonated fatty acids), aluminium sulphate, calcium hydroxide, or ferric chloride; and afterwards with active charcoal. Specified aqueous effluents are those from tallow factories, meat preserving factories, paint spraying booths, abattoirs and machine tools. Specified impurities are hydrocarbons, phosphates, dyestuffs and copper (as Cu<SP>2+</SP>). Apparatus is described and illustrated.
