Title: Improvements in the manufacture and production of n-dihydro-1.2.2.1-anthraquinoneazine fast to chlorine
IPC: C09B5/48
Filed: 1928-07-11
Abstract: 320,397. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.): July 11, 1928. Anthraquinonehydroazines. - N-dihydro-1 : 2 : 2<1> : 1<1>-anthraquinoneazines fast to chlorine are obtained by treating an impure N-dihydro-1 : 2 : 2<1> : 1<1>-anthranquinoneazine, or a methyl derivative or sulphonic 'acid thereof, with manganese dioxide or other higher oxides of manganese in sulphuric acid. The sulphuric acid used may contain up to 33 per cent of water, or weak oleum may be employed. By this treatment the impurities causing the lack of fastness to chlorine are destroyed, while the N-dihydro-1 : 2 : 2<1>: 1<1>- anthraquinoneazine is practically unaffected. The process is particularly suitable for the treatment of the mixture of dyestuffs obtained by alkali fusion of 2-aminoanthraquinone, as described, for example, in Specification 3239/01, and for this purpose it is unnecessary to separate the dyestuff B referred to in Specification 22762/01. The purity of the product can be further improved by choosing energetic conditions for the production of the crude dyestuff mixture, such as lengthening the time of fusion, or by passing air over during the fusion. The process is also suitable for the further working up of the products obtained by the process of Specification 296,106. The products, which are obtained first in the form of azines, may be reduced to the hydroazines in the known manner, for example by dissolving in sulphuric acid and treating with phenols. In example, (1) commercially pure indanthrone, or the dyestuffs obtainable according to Specification 3239/01 and 296,106, while increasing the duration of the alkali fusion, are treated with sulphuric acid of various strengths and artificial manganese dioxide or pyrolusite, (2) 3 : 3<1>-dimethyl - N - dihydro-1 : 2 : 2<1> : 1<1>-anthraquinoneazine is similarly treated, and (3) Indanthrene blue R.S. is sulphonated with a mixture of boric and sulphuric acids, the sulphonation mixture is treated with a suspension of pyrolusite in sulphuric acids, and the product obtained reduced to the hydroazine by treating with a reducing agent, such as crude carbolic acid, in sulphuric acid. Specification 23875/09 and 184,193 also are referred to.

Title: Improvements in treating the surface of paper, cardboard and the like
IPC: D21H19/52
Filed: 1936-07-24
Abstract: 480,679. Surface treatment of paper or cardboard. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.) July 24, 1936, No. 20540. [Class 96] The surface of paper or cardboard is treated by acting with an aqueous solution of a water soluble cellulose ether or an alkaline solution of a water insoluble cellulose ether on the paper strip while it is on the sieve of the paper machine, the said cellulose ether solution containing fillers and if desired a starch preparation such as potato meal, maize starch, or hydrolyzed starch. When cylinder machines are employed the cylinder preferably has a greater diameter than that of the usual cardboard machines. Suitable water soluble cellulose ethers are the ether formed from alkali cellulose and chlorethane sulphonic acid, cellulose glycol ethers containing a free OH group in the glycol radicle, and ethers of alkali cellulose with chloracetic acid or its esters. A suitable water insoluble ether is cellulose methyl ether. Suitable fillers are satin white, titanium white which consists of titanium oxide and barium sulphate, blanc fixe, kaolin, and talc or any filler with a particle size less than À4Á. When an alkaline cellulose ether solution is employed it may be subsequently acidified by treating with acid solutions, e.g. aqueous aluminium sulphate on the paper-making machine or in a brushing machine, or by treatment with steam laden with acid vapours in the dry part of the machine or while hanging. Waxes such as Japan wax or Montan wax may be added to the cellulose ether solutions to increase the lustre of the paper surface. Specifications 423,471 and 458,815 are referred to.

Abstract: 1,261,577. Selective printers. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP. 22 April, 1969 [22 April, 1968], No. 20606/69. Heading G4H. [Also in Division B6] A high speed printer comprises a plurality of type wheels 1 spaced uniformly along and disposed tangentially to the print line, said wheels rotating synchronously and each carrying four circumferential bands of type, being axially displaceable to bring a selected band into register with the print line, a hammer 3 behind the paper opposite each type wheel, means for moving the paper sideways to print all character positions of a line and means for advancing the paper after the printing of a line. The direction of the sideways movement is reversed in successive line printing operations. There may be eight type wheels each carrying four bands of 32 characters. They are driven from a common shaft 7 and can be individually raised to one of four levels by a pair of solenoids 67, 69 which are energized or not and act through a lever mechanism. The shaft 7 carries a pulse generator 8, 9 the pulses being used to indicate the angular position of the typeheads. The paper is mounted on sprocket bands 17L and 17R and these are displaceable left or right for example by a rotary thread 12 giving eight spacing positions. At each side there is a detector providing a signal indicating that the paper has reached the end of its travel in that direction and the direction of travel is then reversed. Data corresponding to a line of characters to be printed is entered into a circulating store via a buffer store. The stored line of characters is read out in an order corresponding to the direction of movement of the paper carriage.

In a multi-stage carburetter with a manually operated primary throttle valve 3, Fig. 1, and a secondary throttle valve 4 operated by a suction responsive device 12 through a resilient link 26, means controlled by the primary throttle 3 hold the secondary throttle 4 closed until the primary throttle is opened to a predetermined position. In Fig. 1 the secondary throttle 4 is operated by a diaphragm 12 actuated by suction from the carburetter Venturis 5, 6. A lever 22 loosely mounted on the primary spindle 8 is urged by a spring 24 against a stop 23 on a lever 16, fast on the secondary spindle 17, to hold the secondary throttle closed. When the primary throttle opens to a predetermined limit, a projection 35 on its operating lever moves lever 22 away from the stop 23, permitting the suction actuated diaphragm 12 to open the secondary throttle. In a modification, Fig. 3 the diaphragm is disconnected from the suction connection 15 by a valve 30 until the primary throttle valve is nearly opened, when a projection 28 on its operating lever 7 lifts valve 30 to transmit suction to the diaphragm to open the secondary throttle. A second projection 22a on lever 7 positively closes the secondary throttle 4 with the primary throttle 3.
