IPC: G01G1/24
Filed: 1963-05-07
Abstract: 970, 026. Weighing apparatus calibration. TOLEDO SCALE CORPORATION. May 7, 1963, No. 17901/63. Heading G1W. A fan type weighing machine, Fig. 1, has a calibrating means including a spring 95 (Fig. 7) operatively connected to its indicator system which is selectively adjustable so to adjust the sensitivity of the scale that there is a linear relationship between the weight of a load and the distance moved by the indicator. Upward movement of the end of a beam 32 (Figs. 4, 7) where it engages a counterbalance spring 33 (Fig. 4), due to a load on weigh pan 28, is transmitted to the lower end of a strut 70 through a flexible strip (Fig. 8, not shown). The upper end of the strut is connected to a crank member 65 fixed to a shaft 57 which carries indicator pointers 30 (Fig. 1). A calibrator spring 93 is hooked to the crank member and to an end of a calibrator arm 97 carried in slots in a calibrator tube 56. The arm 97 is adjustable up and down in the slots in which it is frictionally held, by means of a screw 103 against the action of a spring 111, to vary the force applied by the spring 95 to the crank and thus to balance out the non-linear error caused by the action of the crank. The force of the spring 95 is also adjustable by means of a U-shaped clip 114 (detailed in Fig. 2, not shown) which changes the number of active turns in the spring. A further means of adjustment is by varying the line of action of the spring 95 by sliding the arm 97 in the slots in the longitudinal direction of the arm. The complete indicator section of the machine can be removed from fixingpoints 42 and remounted in fixing points 45 so that the chart is disposed at an angle of 90 degrees to the position shown in Fig. 1. The sensitivity is adjustable at zero, one quarter, one half, three quarters and full load capacity positions of the scale.

Patent GB-869472-A (GB)
Title: Improvements in or relating to active carbon
IPC: C01B32/336
Filed: 1958-06-05
Abstract: Carbonaceous materials are activated by treating them in a fluidised bed at 800 DEG C. to 1000 DEG C., in which the steam content of the fluidising gas never exceeds 0.65 Kg steam/Nm3 gas. Preferably a natural or reducing atmosphere is maintained throughout the fluidised layer.  The steam is mixed with a carrier gas, for fluidising the layer, which may be any suitable gas, for example nitrogen, carbon dioxide, carbon monoxide, or hydrogen. The temperature may be controlled by not insulating the bed, or by spraying water into the bed, whilst maintaining the steam content at below 0.65 Kg/Nm3, or by having tubes containing water in the treatment zone, thereby generating steam which may be employed elsewhere.  The activation may be effected in an insulated combustion chamber.  Especially suitable carbonaceous materials are hard coals which have been preoxidised with air, for example in a rotary drum or fluidised layer at 200-300 DEG C.  The hard coal preferably contained 18-38% volatile materials.

Title: Manufacture of liquid hydrocarbons from gaseous and solid carbonaceous materials
IPC: C07C9/14
Filed: 1939-06-21
Abstract: 530,291. Coking processes. OCON, E. A. June 21, 1939, No. 18063. [Class 55 (i)] Unsaturated gaseous hydrocarbons are polymerized in the presence of a solid carbonaceous material such as coal while undergoing distillation, the coal being pre-heated to above 425‹C. and the hydrocarbons at from 540‹ to 730‹C. being passed through the preheated coal to remove volatiles therefrom' and form coke, the volatile distillates and polymerization products being recovered. A high yield of anti-knock fuels is obtained, and the carbonized residue is gasified with steam leaving a highly absorbent ash. An intermittent or continuous process may be employed and in the latter case the solid fuel is pulverized and agglomerated with a substance such as silica gel which, on drying, forms porous refractory masses which may be activated by contact with acidic gases. In Fig. 1, one or more gas generating chambers A, B are used, each containing a grate 3 supporting a coal bed 4. Hot combustion gases are supplied through conduits 9 to heat the coal quickly to above 425‹C., the waste gases passing to a conduit 11. In the second stage, hydrocarbon gases heated to between 540‹ and 730‹C., are passed through the coal from an inlet 12, these gases consisting mainly of ethane, propane or butane, and being converted into olefines. A pressure of between 200 and 500 lb. per sq. inch may be employed. The various products are withdrawn through pipe 26 to a fractionating and recovery plant. After a short purging of residual volatiles by steam from pipe 13, this coke bed is blown with air from pipe 14, and the hot combustion products passed through pipe 10, manifold 15, and inlet 9 to the base of generator B to pre-heat the coal therein. Water gas is then obtained by passing the steam from inlet 13. A final stage may be the passage of hot hydrocarbon vapours through the ash and coke remaining from the water gas process. Generator B is then worked in the same manner as generator A. In Fig. 2, which shows an apparatus for a continuous process, dry powdered coal is fed from a hopper 29 into a furnace 31 having a rotating helical scraper 32 for mixing the coal with the adsorbent gels, and for exposing them to hot combustion gases from an inlet 33, external heating means being, if necessary, provided. The heated material, pulverized in a grinder 36, is fed together with a gaseous activating medium into a reaction tube 38 into which is passed hydrocarbon gases heated in a coil 41 in a furnace 42. The solids are separated in a separator 43 by baffles 44 and the distillates passed to a fractionator 47 through a filter 45. Superheated steam may be injected through pipe 51 to drive residual volatiles from the coked particles.
