Abstract: 948,925. Copy-holders. E. W. G. BAGLIN. June 23, 1961 [May 13, 1960], No. 17029/60. Heading B6W. A typist's copy-holder comprises a baseplate 10 mounted on rubber feet 13 and having a clip 11 at its top edge to secure the sheet to be copied thereto; locating posts 12 are provided on the base-plate for use with perforated sheets. A line-indicator 24 is mounted on a plate 20 part of which is slidably located in a housing 14 mounted at one edge of the base board and part of which projects through a slot 19 in the side of the housing 14. The lineindicator is secured to a block 22 which is slidable vertically by means of a handle 23 in a pair of vertical guides 21 secured to the projecting part of the plate 20 so that the lineindicator can be raised to allow insertion of the sheet to be copied beneath it. A block 25 is mounted on the part of the plate 20 within the housing 14. An actuating plate 26 is slidably mounted in the housing 14 between spaced upper and lower pairs of rollers 37, 27 and is biased upwards and to the left, as seen in Fig. 3, by springs 34. A recess 30 on the upper side of the plate 26 is engaged by a pawl 31 pivoted to a lever 16 of which one end is pivoted to the housing at 33 and the other end projects through a vertical slot 15 in the housing and carries a button 17. Downward pressure on the button 17 causes the pawl 31 to urge the actuating plate 26 downwards and to the right until it abuts against a stop 29 which is adjustable by means of a screw 28. In the course of this movement the underside of the plate frictionally engages the top of the block 25 and advances it together with the parts 20, 24 a short distance to the right corresponding to the width of a line of the matter to be copied. When pressure on the button 17 is relaxed the springs 34 return the plate 26 to the position shown while the block 25 remains in the position to which it has been moved. Further pressure on the button advances the block another step. The base-plate 10 may have a hinged extension 10a in which ease the lineindicator 24 is hinged at 40.

Title: Process of recovering sulphur from gases containing sulphur dioxide
IPC: C01B17/04
Filed: 1935-06-14
Abstract: <PICT:0439467/III/1> In the recovery of sulphur from gases containing sulphur dioxide by reduction with carbon or carbonaceous material followed by treatment with a catalyst, the gases leaving the reduction stage are first ionized and the impurities are then precipitated in a separate electrical field constituted by two non-ionizing electrodes, one of which is constructed as a catalyst surface. The impurities, such as coal or coke dust, arising from the reduction process are thus prevented from reaching the catalyst. In the arrangement shown, the impure gases are ionized by the discharge from electrode 1 mounted in an earthed casing 2, and the impurities are subsequently removed by a non-ionizing field between the earthed casing 4, acting as a collecting electrode, and an electrode 3 of the same polarity as the discharge electrode 1.  The electrode 3 is constructed as a catalyst surface through which the cleaned gases pass.
