Patent GB-334043-A (GB)
Abstract: 334,043. Sandison, A. G. S. Aug. 12, 1929. Dividing-engines.- In apparatus for marking graduations on a scale in which there may be inequalities in the subdivisions at different parts of the' scale, means for indexing the scale is connected to the movable scale of a chart-plotting device so that known points on the scale may be plotted to allow a calibration curve to be drawn, the positions of the scale divisions then being determined by moving the indexing means to bring the divisions of the movable scale in turn into registration with the curve. The instrument shown is for graduating circular scales, the instrument dial 3 being mounted on a turntable 1 graduated in degrees 4. A gear wheel 6 carried by the table engages a rack 7 carrying at its lower end a transversely arranged scale 13 extending over a chart surface 12. An index 5 is disposed adjacent the table 1 and marking means 15 are mounted over the dial 3. Assuming the instrument to have been tested against a standard at various points on the scale, the table 1 is moved so that the index 5 indicates in turn on the scale. 4 the readings obtained in the test and marks are made on the chart 12 at the points on the scale 13 representing the corresponding readings on the standard instrument, the marks thus obtained being joined by a smooth line 16. The table 1 is then moved to bring the division of the scale 13 in turn into registration with the line 16 and in each postion so obtained the dial 3 is marked by the means 15.

Title: Improvements in cooling apparatus
IPC: F28D11/02
Filed: 1946-11-11
Abstract: 631,963. Cooling granular, pulverulent, and like materials. FULLER CO. Nov. 11, 1946, No. 33498. Convention date, July 3, 1941. [Class 64(ii)] Pulverulent, granular or crushed material is cooled by directing it to an enclosed supply header from which it passes in a horizontal direction in an annular layer between and in contact, on one side, with a surrounding cooled surface and, on the other, with a rotating cylinder filled with a cooling medium and having a diameter substantially greater than the thickness of the annular layer of material, the chamber being maintained under a uniform reduced pressure to remove moisture. Cement as delivered from grinding mills (not shown) is cooled in the apparatus shown in which front and rear headers 11 communicate by means of a connecting casing 12 which is surrounded by a jacket 14 and contains a hollow shaft 21 extending into the headers, both the jacket and shaft communicating with a cooling medium, e.g. water, supply by means of pipes 16, 32 and with outlets 19, 34 respectively. Further the shaft 21 is rotated by a motor 36 and the cement is advanced through the annular space between the casing and shaft by means of screw flights 37 on the latter, the water vapours appearing during treatment being removed by vacuum ducts 52, 55. The diameter of the casing 12 is less than twice that of the hollow shaft 21. An annular guard 38 and double screw flights 39 in the front header keep the cement away from the grease-grooved openings 25 as it is delivered from a feed housing 48. A similar guard and reversed double flight arrangement exists in the rear header, a discharge port from which may communicate with a lower casing 13 in which rotates a shaft similar to the upper shaft 21 but turned end to end and rotated at greater speed. In this way the cement is returned to the lower half of the front header and thence to a discharge hopper 58 connected to a vacuum duct 57. A system is described in which batteries of such cooling units are used in series or some are bye-passed according to requirements.

[Also in Division F4] Iron ore pellets formed in drums 4a, 4b, are conveyed at 6a, 6b to a conveyer belt 8 which passes around a tripper carriage 16 so as to deposit the balls in an even layer across a roller conveyer 12. The latter feeds the layer on to a circular travelling grate 1. The carriage 16 is reciprocated by the action of a double acting hydraulic cylinder 18 on the main machine frame co-operating with a piston-rod 19 connected resiliently at its opposite end with the frame of the carriage 16. The cylinder 18 is energized by a pump 3, the output of which is varied by a lever 43 acting at 44 on a cam 45 carried by the carriage 16. The speed of the belt 8 may also be varied and it is tensioned by a counterweight 37. The belt 8 may discharge directly on to the grate 1 instead of via the conveyer 12.

Title: Improvements in the manufacture of shaped articles of cellulose derivatives
IPC: B29C33/66
Filed: 1935-12-05
Abstract: Articles made from solid compositions having a basis of cellulose acetate or of ethyl cellulose are moulded by contact with a surface of ethyl cellulose or of cellulose acetate respectively.  By the use of such surfaces no adherence between the composition and its mould occurs.  The method is particularly applicable to the production of moulded articles from heated cellulose acetate compositions by means of wooden &c. moulds coated with ethyl cellulose.  Another application is found in the sheathing of the aeroplane propellers with cellulose acetate sheet; in this case a layer of ethyl cellulose either as a coating or a separate sheet is interposed between the cellulose acetate sheet, which may have been softened with solvent, and the rubber bag by which the pressure within an enclosing autoclave is applied to the parts to be sheathed.
