Abstract: 1499779 Scrubbing gases METALLGESELLSCHAFT AG 5 May 1975 [5 Feb 1975] 18832/75 Heading C5E In a process for the purification of crude gas produced in a gas producer 1 by the pressure gasification of solid fuel with steam and oxygen, the gas, which leaves the producer at a temperature of 400-700 C. and contains dust and hydrocarbons, is sprayed in a cyclone scrubber 6 with 0À5-6 litres water per scm. of gas, the temperature of the water being 160-300 C. whereby dust and hydrocarbons are removed, and the gas is cooled and saturated with water; the gas 14 leaving the scrubber is then passed to a second scrubbing stage where it is further scrubbed with water at 160-300 C., at a rate of 0À1-0À3 litres per scm. of gas. In the embodiment shown, the second scrubbing stage is performed in a radial flow scrubber 16, but this may be replaced by a Venturi type scrubber. The scrubbing stages are performed under the same pressure (4-150 bar) as the gasification reaction. As shown, the dust and tar containing water from the cyclone scrubber 6 is passed to a tar separator 11, from which dust containing heavy tar is recycled to the gas producer and dust free water which may also contain some hydrocarbons is passed via line 10 to the pressure heater 9 which feeds hot water to the cyclone scrubber 6. Water 17 from the heater 9 is passed to the radial flow scrubber 16, which is of the type described in 29917/73. In a further embodiment (Fig. 3, not shown) a conventional desulphurizer is incorporated into the purifying system, between the first cyclone scrubber and the second scrubbing stage.

Title: Improvements in the production of engine-divided scales
Inventor: TINDALE JOHN
Filed: 1950-07-28
Abstract: 703,161. Dividing-engines. ELLIOTT BROS. (LONDON), Ltd. July 27, 1951 [July 28, 1950], No. 18941/50. Class 97(3) [Also in Group XL(b)] To produce a finely subdivided scale on a table, two members are provided, one connected with the table bearing a series of marks spaced by an integral number of subdivisions and the other located adjacent the first and bearing a series of marks of spacing equal to that of the subdivisions in the scale, means being provided for displacing the table and the first member so that each registration of a mark on this member with one of those on the second is detected photo-electrically to produce a corresponding mark on the scale. The invention is described with reference to dividing a circular scale 6 on a rotating table into minutes of arc. Mounted on the same table is an opaque scale 5 the periphery of which is divided into 180-2 degree intervals by transparent marks. This table is rotated at a constant speed by a geared motor 38. Near the edge of scale 5 is mounted a graticule 17 the marks of which are spaced in minutes of arc and which is supported on leaf springs 30, and provided with a ball-ended screw riding on scale 5 to maintain accurately the distance of the graticule from the scale. Light from a source 34 is directed on the graticule through a condensing lens 36 and then passes through the transparent marks on the scale 5 to a photo-electric cell 35. Thus as a transparent mark 9 aligns with each of the transparent marks on the graticule in turn a series of pulses are sent out. Each pulse clutches a constantly rotating motor 14 to drive the film feed and shutter mechanism of a cinematograph projector 12 so that the film is advanced one step and an image of a line on it projected on to the photographic surface of the scale 6. A counter 39 stops the mechanism when 21, 600 marks have been made. The size of the marks projected is determined by a diaphragm in the projector so that the film markings may be larger than the printed marks. The invention is stated to be suitable for printing evenly spaced markings in the binary notation. Numbers are represented in sequential spaces on the film in the projector and are printed as radial lines consisting of a number of elemental areas each area being of one of two different characters.
