Title: An improved disc roller classifying grate for coal
IPC: B07B1/15
Filed: 1936-01-18
Abstract: 448,838. Sifting - apparatus. KRUPP GRUSONWERK AKT. - GES., F., Buckau, Magdeburg, Germany. Jan. 18, 1936, No. 1705. Convention date, March 18, 1935. [Class 117] In screens of the kind comprising a series of rollers provided with spaced discs 4, Figs. 1 and 2, of three - arc formation, the spacing betweer the edges of the discs and also the space enclosed between corresponding discs on succes. sive rollers increase in size in the conveying direction sc as to permit cubical and flat shaped materials such as coal and shale of corresponding sizes to be graded together. This effect may be obtained by decreasing the size, and the thickness of the discs on successive rollers. The speed of rotation of the rollers decreases in the forward direction. In the construction described, three screens 1, 2, 3 are arranged in stepped series. In the first two screens, the discs are spaced by members 5 which may be annular or of the same shape as the discs ; in the last screen, the spacing members 6 are of the same shape as the discs. The tail-end rollers of the last screen may comprise alternate discs 4<1> of smaller size than the other discs on the same roller. Stationary clearing fingers may be provided to work between the discs.

Class 17(2) A sole and upper of thermoplastic sheet material are joined by thermal welding, and simultaneously the out-turned flange of the upper and the border of the sole are jointly thermally indented to provide a line of weakness for tearing off the unwanted margins. The welding is effected electrically using a top plate thermal electrode and a bottom annular thermal electrode with an upwardly protruding edge which forms the indentation. Preferably the plastic is unlined, but it may have a lining of relatively open mesh or fine tissue, or of soluble fabric, e.g. silk or rayon, which may be dissolved, and if necessary washed off, along the line of weld.

Title: Improvements relating to the compounding of rubber or the like
IPC: B29B7/54
Filed: 1948-01-21
Abstract: 632,051. Mixing appliances. REDFERN'S RUBBER WORKS, Ltd., and BROWN, F. E. Jan. 21, 1948, No. 1868. [Classes 59 and 86] A machine for compounding rubber &c. with powdered materials comprises a compounding roller 2 mounted in a casing 4 which extends around most of the surface of the roller leaving a compounding space 5. Rubber &c. is fed into the machine in small pellets or cubes together with the powdered materials along the whole length of the roller by means of a hopper 1. An adjustable feed roller 3 in conjunction with the roller 2 forms the nip of the machine and is driven independently of the roller 2. The roller 2 is of a sufficiently large size to enable the materials to be compounded in passing once through the space 5; they are then stripped from the roller 2 by a scraper 8 and pass to a delivery surface 26. A scraper 7 is spring mounted to prevent materials adhering to the roller 3. A modification is described in which a resiliently mounted boosting roller is inserted into the casing 4, being intermittently accelerated to facilitate the compounding. The casing may be eccentric to the roller 2 to provide a thickening of the space 5 in the direction of rotation of the roller 2. The delivery surface 26 of the machine may form the feed roller of another similar machine or a sheeting mill, or may be a conveyer belt in connection with a two roll sheeting mill or an extrusion machine. Specifications 536,421 and 610,560, [Group V], are referred to.

[Class 90] [Also in Group IV] Iodine and other substances are obtained by digesting seaweed with a weak aqueous acid solution, e.g. dilute sulphuric acid, separating the acid extract and treating it, preferably hot, with insoluble copper compounds, e.g. cuprous chloride or cuprous oxide to form copper iodide compounds which are separated by filtration or sedimentation. Iodine is then recovered by known methods. Further acid is added to the liquor remaining and is used for further extraction. When the content of potash and other salts and organic bodies such as mannitol in the liquor becomes too great for useful extraction, such salts &c. may be recovered by any suitable method or the acid content may be neutralized, e.g. with lime and the mass evaporated for use as a fertilizer. The seaweed may be digested in the natural state, or it may be fermented or wetted before it is digested. The Specification as open to inspection under Sect. 91 includes also the subject-matter of Specification 508,671, [Group IV]. This subjectmatter does not appear in the Specification as accepted.

Title: A character generation system
Inventor: WATSON CHRISTOPHER ALAN
IPC: G06K15/10
Filed: 1970-01-16
Abstract: 1,262,841. Electric selective signalling. STANDARD TELEPHONES & CABLES Ltd. 16 Jan., 1970, No. 2199/70. Heading G4H. [Also in Division B6] A printer which forms a magnetic or electrostatic character image as a mosaic of dots from a matrix of possible dot positions, makes the character font bolder by repeating the last dot in each horizontal line of dots forming a character. In Fig. 3, switch SW1 is set to 1-3, 5-6 to make the font bolder. Character signals representing one line of the ten lines of a dot matrix arrive in 7-bit parallel form at inputs 1A 7A and enter the first seven stages of 8-stage register C1 to C8. Six NAND gates 1D to 6D are connected to the Q output of their corresponding register stage and to the Q output of succeeding stages so that, if the last dot of a line occurs in the first six register stages the corresponding NAND gate operates. NAND gate 16 operates upon any of the register stages being set by a dot signal and via memory element 11 inhibits AND gate 10 to stop clock pulses arriving at 12 from reaching the register. Differentiation circuit R1, C1 differentiates the pulse created by NAND gate 16 to pulse line 34 so setting the memory element of 1E to 6E corresponding to the set NAND gate 1D to 6D. The signal from the set memory element is passed to the NAND gate 27 to 32 of the next register stage which is set upon the arrival on line 35 of a pulse obtained by differentiating at R3, C3 the back edge of a pulse from monostable 25 set by the differentiated pulse of NAND gate 16. The setting of the next register stage thereby repeats the last dot of the line. If register stage C7 is set, stage 8 is set to repeat the last dot by the connection from the Q output of stage C7 to NAND gate 33. The differentiated pulse from R3, C3 resets memory element 11 to remove the inhibit from AND gate 10 so allowing the clock pulses to shift out the contents of the register either serially at terminals 14, 15 as shown or in parallel form.
