Title: Method for conditioning fine-grained material for agglomeration, and an apparatus therefor
IPC: C22B1/14
Filed: 1952-07-02
Abstract: 708,408. Conditioning fine-grained material. REYMERSHOLMS GAMLA INDUSTRI AKTIEBOLAG. July 2, 1952 [July 4, 1951], No. 16622/52. Class 59 A method of conditioning fine-grained material, e.g. pyrites cinders for agglomerating comprises rotating relatively to one another two separate moist and coherent bodies of the fine-grained material each having an abrasion surface whilst pressing the bodies against each other with the abrasion surfaces in contact so as to establish an abrading action between said surfaces, and successively removing from between the bodies the loose material formed between said surfaces. Apparatus for carrying out the method comprises fixed and rotary hollow end plates 5 forming a cylindrical chamber 4 to which the raw material and a liquid are supplied under pressure until the chamber is full and the material tightly packed when the rotary end plate is rotated to cause shearing to take place along the medial line of the material in the chamber so that two abrasion surfaces are formed. The ground material is urged out through an adjustable'slit 8 between the flanges 13 of the end plates. The raw material is supplied to the chamber from a hopper 1 by means of a screw conveyer 3, or a plunger compresser, to which a liquid is supplied at 7. Radial fins 6 on the end plates prevent the material from rotating within the cavities of the end plates.

Abstract: 1,094,790. Printing apparatus; cleaning blanket cylinders. AGFA-GEVAERT A.G. April 15, 1966 [April 15, 1965], No. 16661/66. Heading B6C. A cylinder in a rotary offset printing machine has tensioned therearound a sheet for cleaning the blanket cylinder the operable arrangement of the machine being such that the cleaning sheet may be brought into contact with the blanket cylinder after the printing operation. In the rotary offset machine shown a swing- ingly mounted blanket cylinder 11 coacts with a combined forme and cleaning cylinder 4. The latter mounts a single sheet comprising a printing portion 7a and a cleaning portion 7b. The operation of the machine is controlled by a lever 31 settable into positions " D," " V," " N " and " R." In the position shown, " V " -pre-inking-the inking and dampening mechanism is tripped " in " by the lever, linkage and cam mechanism which controls the machine. The blanket cylinder 11 is brought into contact with the printing portion 7a of the sheet but not the cleaning portion. The sheet feed mechanism is inoperative. The pre-inking of the blanket is thereby effected. When not required the machine is shut down and the lever 31 is moved into the " night-setting " portion " N " in which both inking and dampening mechanism and the blanket cylinder are tripped " off " the cylinder 4 and the paper feed becomes inoperable. For printing the lever is moved to " D." In this position the blanket is inked by the printing portion 7a then a sheet is fed from the pile 43 between the cylinders 4 and 11 the cleaning portion 7b acting as a pressure backing for the sheet being printed. When the setting lever 31 is moved to the cleaning position " R " the cam 14 rotating with the cylinder 4 causes the blanket to move from the cylinder 4 during passage of the printing portion 7a between the bight and to contact the cylinder 4 during passage of the cleaning portion 7b. The sheet feed is switched out. To assist cleaning, a hand wheel is located at the end of the cylinder 4 by which the machine drive to the cylinder may be interrupted. By rotating the hand wheel it is possible to bring successive parts of the cleaning portion 7b into contact with the blanket cylinder. In a modified apparatus an impression cylinder 64 (Fig. 3, not shown), which may be fitted with a hand wheel in a similar manner to that described above in connection with cylinder 4, contacts the blanket cylinder and carries a cleaning sheet which serves during the printing operation as an underlay. Fig. 4 (not shown) shows a hollow forme cylinder 52 having two rotatable rollers upon which the ends of the combined printing and cleaning sheet are wound. By suitable manipulation of the rollers the cylinder may mount either an entire printing or cleaning surface. In a modification of the cylindrical construction of Fig. 4, the two rollers are eliminated being replaced by a single windable hollow cylinder concentrically housed in the forme cylinder.

Filed: 1940-12-02
Abstract: 548,760. Pre-treating oils to be cracked. STANDARD OIL DEVELOPMENT CO. Dec. 2, 1940, No. 17139. Convention date, Dec. 2, 1939. [Classes 32 and 91] In the catalytic cracking of hydrocarbons oils containing aromatics, the deposition of carbon on the catalyst is reduced and the yield of cracked hydrocarbons increased by pre-treating the starting material with selective solvents to remove the condensed ring aromatics while leaving a substantial amount of the uncondensed ring aromatics in the material. To determine the extent of the pre-treatment necessary in any particular case, the specific dispersions of successive fractions of extract are observed and the extraction discontinued when all constituents with specific dispersions above 200 have been removed, e.g. when the last removed extract has a specific dispersion of 190 or, at the lowest, 150. Fig. 1 shows an apparatus for carrying out the process. Oil from the pipe 10 is mixed with a selective solvent such as methyl cellosolve in the chamber 11 and passed to a settling tank 14. From here the raffinate is passed to a solvent distilling chamber 16 to vaporize any solvent contained therein while the oil freed from solvent is passed to the cracking unit through the pipe 21. The extract is passed through a series of reflex separators 23, 27, 30 where additional oil may be removed by decreasing the temperature, or adding water from the pipe 24. The additional oil passes back to the pipe 10 through the pipe 25, while the water and solvent is passed to a solvent till 35 where the solvent is distilled off and passed to a condenser 19. The condensed ring aromatics remain in the still 35.

[Class 112] Stitches and stitched seams.-A flexible imitation cross-stitch seam is formed by two threads, 20, 21, Fig. 4, laid in zig-zags-so as to interlink on the surface at 22 and to penetrate the fabric at the outer vertices 23, 24, 'the threads being interlinked at the back, preferably, as shown at 27, close to one edge of the seam. The seam is preferably produced in a zig-zag sewing-machine by folding the fabric or fabrics so that alternate stitches are made through the fabric or fabrics and adjacent to the folded edge 19 thereof, as shown in Fig. 5; the threads are preferably somewhat slack, so that the fold can be opened out flat or the fabrics opened to lie edge to edge, but the seam may be similarly used with tight thread to secure a piping cord in a fold. The seam is designed particularly for attaching the insole of a slipper to a binding strip which is fixed to the main sole; it may also be used for producing an ornamental. beading on a piece of fabric, as shown in Fig. 9. Work-guides; presser-feet.-For producing the seam in a zig-zag sewing-machine, an upstanding guide 35, Fig. 5, adjustably fixed to the.workplate, may be used, with a presser-foot 33 having a notch to co-operate with the guide 35 and a needle slot 34. Flattening stitched seams.-When the seam is used for connecting the edges of two fabrics, it is flattened after making, the slackness of the threads allowing this. This operation may be performed by means of a roll press having milled rollers 31, 32, Fig. 7, which may be incorporated in a sewing-machine.
