Patent GB-862018-A (GB)
Title: Water-dispersible carbon black and production thereof
Inventor: DONNET JEAN-BAPTISTE ALEXIS
IPC: C09C1/56
Filed: 1958-01-16
Abstract: A water dispersible carbon black is produced by contacting carbon black with an aqueous oxidizing solution of nitric acid, hydrogen peroxide, potassium permanganate, potassium chromate, potassium bichromate, sodium chlorate or persulphuric acid, of sufficient strength to provide a volatile content (as defined) of the carbon in the final product of at least 10% wt., and at a temperature of 20 DEG C. to the boiling point of the solution, the oxidized carbon black being subsequently separated and adherent oxidizing agent removed therefrom.  The volatile content of the carbon black may vary from 10 to preferably 50% wt.  Aqueous, say 19-40% wt., nitric acid, as the preferred oxidizing solution may contact carbon black in amounts 40-400 gms. of black/litre of nitric acid solution, for a period of 2-24 hours at a temperature above 50 DEG  C. especially at the b. pt. of the solution.  The oxidized black is freed from foreign ions particularly those present through use of oxidizing solutions yielding polyvalent cations, e.g. potassium chromate, bichromate, and permanganate, by washing with water or aqueous solutions of ammonia. The oxidized black has an average particle size of 10  to a few microns and possesses surface hydrophilic groups, e.g. CO2H and OH, which afford the black ready dispersion in water.  The hydrophilic groups may be estimated by their property of liberating acetic acid from aqueous solutions of calcium acetate.  Modifications of the properties of the oxidized black may be effected by substitution of the hydrophilic groups with other groups, e.g. CO2Me, OMe and COCl by chemical reaction.  Use of the oxidized blades in rubber latex compositions, paints, lacquers and varnishes, printing inks; as aqueous pasty masses in place of colloidal graphite as a lubricant; as an ion-exchange agent; and as a pigment for paper, cements, mortars, &c. is referred to. Specifications 668,724 and 769,018 are referred to.

Abstract: 525,265. Cellulose esters. STANDARD TELEPHONES & CABLES, Ltd.. NEW, A. A., BECKWITH, D. R., and WILTSHIRE, W. A. Jan. 18, 1939, No. 1757. [Class 2 (ii)] Cellulosic material is passed in continuous manner in the form of a sheet or thread through a bath or baths containing esterifying agents capable of forming cellulose acetates, propionates, or butyrates, and the esterification is effected in uniform manner in the presence of perchloric acid and under such conditions that the fibrous form of the cellulose is retained. The degree of esterification may be adjusted by variation of the speed of travel of the material through the bath or the temperature of the bath or the concentration of the catalyst. The catalyst may be added to the bath containing the acid anhydride or it may be contained in a pretreatment bath. The anhydride bath may contain solvents or non-solvents for the cellulose ester e.g. acetic acid or toluene. The cellulosic sheet may be passed in succession through a bath containing the acid or acids, the ester or mixed ester of which is to be formed, through a bath containing perchloric acid, and then through another bath containing the appropriate anhydride. The sheet may then pass through the air and between calendering rollers into a washing tank, and then through a drying chamber. The sheet may be subjected to drying before the esterification treatment. Esterification may proceed up to the tri-acyl stage. The treated materials are suitable for electric insulation purposes. Examples describe the treatment of paper including wood-pulp-manilla paper of various thicknesses. As shown, paper is drawn from roll 4 and passed between steamheated drying rolls 5. It then passes through tanks A, B, C, in which it is guided by rolls 1, 3, and through chamber D and heated passage D<SP>1</SP>. It passes through washing tanks E, F, G, and on to take up roller 6. The paper strip is sprayed with water from the pipes 10. Tank A may contain glacial acetic acid, tank B a solution of perchloric acid in acetic acid, and tank C a mixture of acetic anhydride and toluene. Specification 494,253 is referred to.

Title: Improved apparatus for arranging and feeding crowns and like articles
IPC: B67B3/064
Filed: 1925-01-20
Abstract: 245,602. Carpmael, W. P., (Crown, Cork, & Seal Co. of Baltimore City). Jan. 20, 1925. Crown corks,' applying.-Relates to apparatus for arranging and feeding articles such as the crowns of crown corks,' in which a disarranged mass of articles is received by a receptacle and arranged in a single upright row in an annular raceway therein, indiscriminately faced, the raceway having an exit opening to which the articles are successively presented to be divided into two sets according to the way they face, the direction of facing of one set being then reversed. According to the invention, one set of articles is delivered to a reversing raceway having a discharge opening located at 180 degrees from the point of delivery and the reversing is accomplished by carrying the delivered articles to that discharge opening. As shown, crown corks ' are fed by a spout 12 on to a dial 17 rotated within a receptacle 14, the number of crowns passing into the receptacle being controlled by a tubular member 92 adjustably supported on screws 94 carried by arms 95 secured to the receptacle 14. The crowns slide down the conical upper surface 32 of the dial 17 into a raceway 16 between the vertical edge of the dial and the wall of the receptacle 14, and during this movement clusters of crowns are broken up by clearers 47 secured to the receptacle 14 and irregularly spaced buttons 97 on the dial 17. In the raceway 16 the crowns form a single row standing on edge but some face outwards and some inwards. Spring-pressed plungers 41 mounted on the dial move them around the raceway 16 to a slot 33 in the bottom thereof, down which they are guided by a curved member 46 integral with one of the clearers 47. Beneath the slot the edges of the crowns, according to the way the crowns face, engage behind or in front of ribs 38, Fig. 9, which project inwardly into the passage of a selecting device 34, those facing outwards being thus directed into a vertical shoot 35 whilst the others pass down a shoot 36 and are guided by a curved block into and along a reversing raceway 56, similar to the raceway 16. A dial 51 secured to the shaft 18 of the dial 17 moves the crowns around the raceway 56 through an arc of 180‹ causing them to face the same way as those in the shoot 35 when they slip down a shoot 57 terminating beside the shoot 35 in a magazine 68. In this magazine an horizontal plunger 78, immediately above the bottom plate 69 thereof, is reciprocated by a crank driven rod 85 connected to it by a friction slip connection, the plunger pushing the crowns to a shoot 74 through which they pass singly to an assembling machine. In the event of a jam of crowns, the friction slip connection renders the plunger 78 inoperative.
