Title: A printing press
IPC: B41F33/08
Filed: 1960-02-23
Abstract: 910,230. Printing-machines. HARRISINTERTYPE CORPORATION. Feb. 23, 1960 [March 2, 1959], No. 6305/60. Class 100 (2). Cylinder trips.-In a throw-on and throw-off mechanism for sheet-fed rotary offset printing- machines wherein the gaps of the cylinders are in registry with each other during a part of each rotation and one of the cylinders is movable between operative and inoperative positions, the retracting movement is initiated while the gaps are in registry at the printing line and the advance movement of the cylinder is initiated at a point in the rotation of the cylinders in advance of the point at which the throw-off movement is initiated and is completed after said point and before the trailing edges of the gap pass the printing line. The blanket cylinder 11 is thrown off the plate cylinder 10 by rotating an outer, eccentric 15 clockwise by moving upwardly along its length a shift bar 31, whereby through a bell-crank 32 and links 36, 37 a bracket 20 connected to the eccentric is shifted, the eccentric being adjustable by a turnbuckle connection 68 and the link 37. An inner eccentric 14 carries a bracket 18 connected to the bracket 20 by toggle links 22, 23, whereby the eccentric 14 rotates with the eccentric 15. The cylinder 11 is thrown off the impression cylinder 12 by rotating the eccentric 14 clockwise with respect to the eccentric 15, by moving a shift bar 30 downwardly along its length so as to move a toggle link 28 to the left. The pressure of the blanket cylinder against the impression cylinder is adjustable by rotating manually a shaft 136, which through an expansible drive 130, 126 and an arm 121 adjusts the relative position of the eccentrics. The bar 31 is moved upwards by a pin 47 engaging a notch in its left side, and downwards by a pin 48 engaging a notch 61 in its right side, while the bar 30 is similarly controlled by pins 72, 74. The pins are actuated by cams 46, 77 on the plate and impression cylinder shafts. The bar 31 is moved about its pivoted lower end into the path of either the pin 47 or the pin 48 by a rod 62 under manual control or under automatic control when a malfunction of the press is occurring. The bracket 20 is connected by a yieldable device 90 to the bar 30, so that when the eccentric 15 is moved to throw-off position, the bar 30 is moved into the path of the pin 72. The cylinders are provided with gaps 13. The arrangement is such that the cylinder 11 is first thrown off the cylinder 10 and then off the cylinder 12, and is also thrown on to first the cylinder 10 and then the cylinder 12. The cams are so constructed and mounted that the working strokes of the throw-on pins 48, 74 are initiated before the gaps have met and completed after the middle of the gaps have passed each other, while the working strokes of the throw-off pins 47, 72 are initiated after the gaps have met but before the middle of the gaps have passed each other and completed after the gaps have passed.

Title: Improvements in the manufacture and production of new vat dyestuffs
IPC: C09B3/36
Filed: 1927-03-07
Abstract: 273,247. I. G. Farbenindustrie Akt.- Ges. June 22, 1926, [Convention date]. Samples furnished. Benzanthrone dyes.-Hydroxy-derivatives of dibenzanthrone, isodibenzanthrone or their substitution products are converted into alkylethers in which the alkyl group consists of a short carbon chain to which is attached, through the medium of an oxygen atom, a further hydrocarbon radicle. The alkylation is preferably effected by means of arylsulphonic esters of alkyl ethers of di-or polyvalent alcohols. The products, which dye cotton in fast shades from the vat, are unusually soluble in organic solvents and are suitable for colouring lacquers. According to examples (1) the oxidation product of dibenzanthrone (Specification 14498/12) is heated in trichlorbenzene with sodium carbonate and the toluenesuphonic ester of glycol-monomethylether or-monoethylether; (2) the oxidation product of dibenzanthrone is similarly treated with glycol-mono-n-butylether toluenesulphonate; the product is soluble in benzene and other lowboiling solvents and coatings of cellulose nitrate lacquers coloured green therewith possess exceptional fastness. If the glycolbutylethertoluenesulphonate contains some glycolditoluenesulphona.te the product contains a blue dyestuff identical with that from ethylenebromide ; the blue dyestuff remains behind on boiling with monochlorbenzene or butylacetate. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the production of vat dyes from ketones of the perylene series by alkylating with agents capable of introducing a short chain alkyl radicle linked to a further hydrocarbon radicle through a sulphur atom, and mentions the arylsulphonic esters of alkyl-, aryl- and aralkylethers of thioalcohols. as well as of di-or poly-valent alcohols, as alkylating agents. This subject-matter does not appear in the Specification as accepted. Toluene-p-sulphonic esters of glycol monoalkyl ethers are obtained by treating the ethers with p-toluenesulphochloride, in the presence of sodium hydroxide. Specification 193,431 also is referred to.

Title: Mixing apparatus comprising a revolving conveying screw and a liquid supply device
IPC: B28C7/12
Filed: 1953-03-06
Abstract: 728,323. Mixing appliances. NAUTA, J. E. March 6, 1953 [March 8, 1952], No. 6346/53. Class 86. In a mixing machine of the kind described in Specification 599,900, liquid from a supply main enters the mixing vessel through an aperture in the lower end of the side wall, the aperture having a closure device for preventing the material in the vessel from penetrating into the aperture during periods when no liquid is being supplied to the apertures. In Fig. 1, liquid is pumped from a tank 25 into a supply main 26 which communicates periodically with each of three apertures 47 spaced 120 degrees from one another around the vessel 1. The supply of liquid to the apertures 47 is controlled by a three-way cock 35 which is rotated by a chain drive 41 in synchronism with the rotation of the crank arm 7 so that liquid passes through an aperture when the worm 2 is in positions adjacent to and diametrically opposite that aperture. Each aperture 47 is formed as a horizontal slit in a member 50, Fig. 3, which carries a cylinder 48 containing a piston 49. The piston 49 is provided with a pin 53 having at its free end a sheet-like member 54 which exactly fits the slit 47. On the other side, a spring 56 urges the piston towards the vessel 1 so that the member 54 enters and obturates the slit 47. When Irquid supplied under pressure from the main 26 enters the cylinder 48, via ducts 34, 60, it moves the piston 49 against the spring 56 so that the obturating member 54 is withdrawn from the slit 47 allowing liquid to pass into the vessel 1. When the supply of. liquid is shut off, the spring 56 again moves the obturating member 54 into the slot 47. Any liquid which leaks past the piston 49 is returned to the tank 25 by a conduit 62. If necessary, more than three slits 47 may be provided and round instead of slit-like inlet openings may be used. A separate cock for each slit 47 may be used instead of the common cock 35, in which case it is possible to supply a different quantity of liquid to a slit opening according to whether the crank arm 7 is directed towards the slit, or in the opposite direction thereto. When a small amount of liquid is to be supplied, it may be introduced into the vessel with air or carbonic acid gas so that its supply is spread out over a longer period.
