Title: Improved process for rolling thin or middle sheets from sheet bars
IPC: B21B1/38
Filed: 1922-11-09
Abstract: 205,362. Boscarelli, G. Nov. 9, 1922. Rolling.-In a method of producing thin metal sheets the necessity for intermediate heating is avoided by rolling consecutively three or more sheet bars and then piling the sheets and re-rolling, feeding being effected by means of a mechanical lifting device. The sheets 1, 2, 3 are passed by one operator successively through a pair of rolls the sheets being received and returned' over the rolls by a second operator and the rolling operation repeated until the desired thickness is attained whereupon the sheets are piled and re-rolled as at H. The three leaf sheet is then doubled, reheated', and reduced to the final form. In a modification, Fig. 2, four sheet bars are manipulated by two operators, the bars being arranged and returned in groups of two and rolled singly as shown until the final rolling. In a further modification, six sheet bars are manipulated is a similar manner. The mechanical device for lifting the sheets comprises lifting bars 3 having pins sliding in bearings 2 in a table 1, the bars being drawn against the bearings by springs 5. The lifting bars are connected bv hinged members 9, Fig. 10, to a cross piece 12 having rollers 13 which engage a guide block 15. In operation the sheets 19 are fed onto a guard 6 and table 1 is then raised and the sheets lifted by the bars 3. Near the upper position of the table the rollers 13 are disengaged from spring-presed toe-members 18 which move forward so that on the descending movement the rollers 13 pass down the outer guide faces 16. The lifting bars are thus separated so as to pass outside the edges of the sheets which have been passed through the rolls during the movement of the table. A groove 17 is provided for the return of the lifting bars to their normal position at the bottom of the stroke.

Abstract: The invention provides a process for the production of quinacridone quinones in which compounds of the formula <FORM:1009792/C4-C5/1> are heated to form a quinacridone hydroquinone compound of formula <FORM:1009792/C4-C5/2> which is then oxidized to the required quinacridone quinones having formula <FORM:1009792/C4-C5/3> The compounds of formula II in which Ar11 and Ar12 are divalent benzene or naphthalene radicals are novel and are claimed per se.  In the above formula Ar1 and Ar2 are aryl radicals or the corresponding arylene radicals after ring closure and may also be substituted.  X is an alkoxy, cycloalkoxy, aralkoxy or aryloxy group which may be substituted, but preferably X is a low alkoxy group.  Ar1 and Ar2 may be benzene, naphthalene, pyrene, or anthraquinone ring systems.  The ring closure of compounds of formula I to give compounds of formula II is done in an inert organic solvent whilst excluding oxidizing agents at temperatures of 180-350 DEG  C. Mixtures of the solvents may be used including aromatic hydrocarbons, halogenated aromatic hydrocarbons, and derivatives of aromatic carboxylic acids.  Solvents having a reducing action may also be used, alkylene glycol ethers are also refered to.  The oxidation of compounds of Formula II to those of Formula III is carried out in acid, neutral or alkaline media or in organic solvents, oxidizing agents include atmospheric oxygen, nitric acid, manganese oxide, ferric salts, chromates or bichromates and tetravalent lead compound. In organic solvents the halogens iodine or bromine and sodium nitrite are useful.  The compound of Formula II is obtained in fine dispersion when dissolved in sulphuric acid, and then precipitated with water.  Oxidation is preferably carried out in aqueous alkaline media with atmospheric oxygen as oxidizing agent.ALSO:Intermediate compounds 2,5-bis-arylamino-1,4-hydroquinone-3,6-dicarboxylic acid diesters of formula <FORM:1009792/C2/1> in which Ar1 and Ar2 are aryl radicals, X is an alkoxy, cycloalkoxy, aralkoxy or aryloxy group may be produced by reduction of the corres ponding 1,4-benzoquinone compounds with sodium hyposulphate, the 2,5-bis-arylamino-1,4-benzoquinone -3,6 -dicarboxylic acid esters being produced by heating the corresponding 2,5 - bis - halogen - 1,4 - benzoquinone - 3,6 -dicarboxylic acid diesters with amines Ar1NH2 and Ar2NH2, for example in a low alcohol, e.g. ethanol or methanol in presence of an agent buffering acid.  The compounds of Formula I are condensed by heating to give quinacridone hydroquinones of formula <FORM:1009792/C2/2> by heating in an inert organic solvent at 180-350 DEG  C. in the absence of oxidizing agents. These compounds are oxidized to quinacridone quinones (see C4P).
