Abstract: 727,723. Typewriters ; manifolding appliances ; decollating mechanism. LAMSON PARAGON SUPPLY CO. Ltd. Nov. 27,1952 [Nov. 13, 1951], No. 26592/51. Class 16. [Also in Group XVI] Mechanism for feeding superposed webs of continuous stationery through decollating means is driven by a weight falling by gravity. Means are provided for raising the weight automatically at the completion of each descent. Three superposed records webs a with interleaved webs b are passed over separator plates 2-4 the webs a falling into trays a<SP>1</SP>-a<SP>3</SP> and webs b being wound on tubes 7, 8. The spindles 9, 10 of the tubes 7, 8 are driven by a chain 17 passing over sprocket wheels thereon and over a sprocket wheel 18 on the shaft 19. A chain 21 having a weight 30 attached passes over a sprocket wheel 20 on the shaft 19 and over a sprocket wheel 22 driven through a clutch from an electric motor 26. As the weight 30 falls it drives the shaft 19, and hence the tubes 7, 8, through a one way drive until the weight 30 contacts an abutment 33 on a rod 31 to cause the clutch to the motor 26 to be engaged and thus to drive the sprocket 22 to raise the weight 30 until it contacts an abutment 32 to disconnect the clutch drive. The weight can then fall again to drive the tubes 7, 8. In place of the tubes 7, 8 the drive may be used to feed the webs by pin wheels or a tractor unit engaging edge perforations therein.

Title: Process and apparatus for the continuous manufacture of polymer emulsions or dispersions
IPC: B01F27/96
Filed: 1962-06-12
Abstract: <PICT:1003290/C3/1> A vessel 1 for the continuous polymerization of an aqueous emulsion of monomer(s) introduced through inlet 2 is surrounded by two heating-jackets 9, 10 and is internally fitted with a rotatable frame stirrer having stirring-arms 6 parallel to the axis of the vessel, and a scraper disc 7 which can be moved up and down by rod 8 along the axis of the vessel.  The product leaves vessel 1 via outlet 4 and flows through cooler 15 into chamber 16, which is supplied with inert gas, e.g. nitrogen, through conduit 17. The product is discharged through throttlingvalve 19 which maintains the system under superatmospheric pressure to that the evaporation of monomer from the emulsion in vessel 1 is minimized.  The scraper disc detaches deposits of polymer from the surfaces of the stirrer.  The walls of vessel 1 are cleaned either by one or more arms of the stirrer or by the scraper disc. An example relates to the polymerization of an aqueous emulsion containing vinyl acetate, polyvinyl alcohol, tertiary butyl hydroperoxide, and formaldehyde sodium sulphoxylate, introduced into vessel 1 through inlet 2.  A further amount of formaldehyde sodium sulphoxylate is introduced through inlet 3.  The lower heating-jacket is maintained at 80 DEG C., and the upper jacket at 70 DEG  C.  The polymerization is carried out at a gauge-pressure of 1.6 atmospheres. Specification 701,258 is referred to.

Title: Improvements in or relating to formazane azo dyestuffs
Inventor: STEINEMANN WILLY
IPC: C09B62/01
Filed: 1960-08-02
Abstract: The invention comprises formazane azo dyes, and their metal complexes, which in the metal-free state may have the formula <FORM:0959992/C3/1> where R is the residue of a benzene diazo component and X is OH or COOH in an ortho position to the diazo group.  The dyes may be made by coupling 1 mol. of levulenic acid with 2 mols. of an appropriate diazo component with, if desired, subsequent metallization, in known manner, in substance or on the fibre. Coupling is preferably effected at pH 10-14 in aqueous, or aqueous media, at 0-5 DEG  C.  After treatment of dyeings is preferably conducted in the presence of polyalkylene polyamines. Indicated diazo components are 2-amino-1-carboxy- or -hydroxy-benzenes which may be substituted with e.g. carboxy, sulphonamide, which may be N-mono- or di-substituted, alkyl-or aryl-sulphonyl, alkyl, aryl, alkoxy, nitro, fluorine, chlorine and bromine groups.  The diazo components may contain azo groups and be metallizable or metallized and may also contain groups capable of dye formation, e.g. azo dyes, or contain exchangeable hydrogen atoms. Substituents capable of azo dye formation are amino groups or groups convertible thereto, or couplable carbon atoms.  If the diazo components contain exchangeable hydrogen atoms radicals containing a substituent which is easily splittable as an anion and/or C-C multiple linkage, capable of addition, may be introduced into the dye molecule to form a reactive dye.  Copper and nickel are preferred metals.  Dyes without water-solubilizing groups are used as disperse dyes for artificial fibres, e.g. acetylated cellulose and polyterephthalic acid glycol esters. Those with solubilizing groups dye textiles of all kinds, e.g. wool, silk, polyamides and leather are coloured with low molecular weight dyes, and cotton, viscose, cuprammonium rayon and leather are coloured with higher molecular weight dyes, and in both processes the dyes may be metallized in substance or on the fibre. Water-soluble metal complexes may form colour lakes by treatment with calcium, barium, strontium or lead salts.  Examples are provided of the preparation of the dyes, and their metal complexes, and the use of the latter in dyeing various fibres in blue, brown and green shades.

A screw cutting and parting off lathe comprises a bed 1, Fig. 1, carrying a headstock 2 which rotatably supports a work spindle 3 having a chuck 4 at each end, tables 5, 6 which support longitudinally reciprocable slides 7, 8 on which are mounted transversely reciprocable slides 9, 10 and tool carriers 11, 12 mounted on slides 9, 10. Spindle 3 is driven from a motor M, Fig. 2, through gearing 99, the motor being adapted to drive cam-shafts 23, 24, through gearing and dog clutches 22, 27, 31, so as to move slides 7-10. Cam-shaft 23, Fig. 3, is journalled in bed 1, as is cam-shaft 24, and a cam 36 on shaft 23 engages slide 7 to move the latter on rotation of shaft 23. A second cam 40 engages a roller 41 supported from a non- rotatable bracket 42 secured to the spring- urged shank 43 of an hydraulic control valve 44. Rotation of cam-shafts 23, 24 therefore produces longitudinal movement of slides 7, 8, through cams 36, and actuation of valves 44 through cams 40, which actuation controls the transverse movement of slides 9, 10. Valve 44 supplies fluid to a piston 50, Fig. 4, which pivots a lever 52-53, about a shaft 56, to move a rack 60 which rotates a pinion 61 which in turn moves a rack 62 to move slide 9. The incremental feed of slide 9 to produce a tapered thread on the work is provided by a cam 57, secured to a shaft 67 which also has a ratchet secured thereon so that as lever 52-53 pivots, pawls rotate the ratchet and therefore cam 57 to produce the feed. A micro-switch 81a is actuated by (retractable stops 75, Fig. 6, not shown) carried by a wheel 77 to effect electric automatic control of the machine cycle. To move slides 9, 10 without moving slides 7, 8, to part off the work cam-shafts 23, 24 are disengaged by means of a clutch 22 and a cam 82, Fig. 4, is rotated to actuate rack 60, by a gear 85. Gear 85 and its symmetrical gear 85<SP>1</SP> are driven from an electric motor 13<SP>1</SP>, Fig. 7, through a speed variator V, and reduction gear R. Cams 77b, Fig. 4, and 77c, Fig. 3, actuate switches 81b, 81c respectively to produce the required cycle. Slide 9, Fig. 4, is moved rightwardly as rack 60 moves upwardly, but in a modification when an internal bore is to be machined, such upward movement moves the slide leftwardly. A workpiece 97, Fig. 8, is located in the lathe by a stop 14, Fig. 1, carrier 11 has a thread cutting tool 90, a deburring tool 91 and a parting-off tool 92, and carrier 12 has a thread cutting tool 93, turning tool 94, chamfering tool 95 and a parting off tool 96. Clutch 22 is disengaged and carriers 11, 12 are moved in by cams 82 to part off the work and to chamfer by tool 95. Cams 82 are disengaged and clutch 22 is engaged and the work is turned and screw cut by tools 94, 90, 93 with slides 7, 8, 9, 10 being moved simultaneously.
