[Class 143] [See also Group VI] A machine for weighing or checking the weight of cigarettes delivered from a continuous rod cigarette-making machine comprises means for automatically selecting cigarettes at intervals, one at a time, from a stream of cigarettes and transferring them to a weighing or weight checking device having means for repeatedly discharging a single cigarette at each operation, whereby there is always a predetermined number of cigarettes present on the weighing device. In operation a framework 1 carrying the mechanism is lowered by a lever 3 so that a roll 11 engages a collector belt 53 carrying the stream of cigarettes. The roll, operating through gearing, drives a shaft 6 carrying a scoop 17 which is shaped to accommodate a single cigarette. At each rotation, the scoop picks up a cigarette from the belt and drops it into shoot 32 whence it rolls into one of the flutes of a rotary member 33 suspended from a weighbeam 26. A stationary cam 22 actuates a finger 18 so as to retain the cigarette in the scoop until it reaches the shoot 33. A shield 30, also supported by the weighbeam, closes a predetermined number (nine in the present instance) of the flutes so that ten cigarettes always load the weighbeam. The fluted member 33 is rotated one step by a cam and pawl mechanism before each cigarette is supplied by the scoop 17, the rotation causing a cigarette to be discharged over the edge 30<a> of the shield on to the belt 53 and bringing an empty flute into position to receive the new cigarette. The scoop 17 selects one cigarette in every fifty or other predetermined number according to the relative speeds of the scoop and collector belt. The weighing scale is steadied during the stepping of the fluted member 33 by a cam-controlled lever 50 which is brought to bear resiliently on the scale pendulum 31. The weighbeam carries a pointer 27 co-operating with a graduated scale 28.

Title: Process for the catalytic conversion of sulphur containing hydrocarbon mixtures into products of lower boiling point and sulphur content
Inventor: ANHORN VICTOR JOHN
IPC: C10G47/30
Filed: 1954-08-04
Abstract: In processes for the desulphurization and conversion to gasoline of hydrocarbon mixtures containing sulphur and difficultly vaporizable constituents e.g. residual oils shale oils, reduced crudes by processing the oils in admixture with hydrogen in the presence of catalysts maintained in the fluidized state, the process is continued without regeneration of catalyst until tests show that, after a period of constant deposition of carbon on the catalyst, the rate of deposition is beginning to rise rapidly.  Reaction conditions comprising temperatures of from 750-950 DEG C., pressures of 750-2000 lbs. p.s.i., hydrogen-oil ratios of 10.000 SCF hydrogen per barrel oil, gas velocities of 0.01-0.5 ft./sec. and catalyst/oil ratios of 1 : 2-1 : 16 are specified. Catalysts employed are oxides and sulphides of Mo, W, Va, Cr, Co, Fe, Ni, Sn, particularly mixtures of the oxides or sulphides of the iron group with those of Group VI e.g. nickel molybdate, tungstate or chromate.  The catalysts are mounted on porous carrier of the silica-alumina type.  Examples are given of test runs in which at specified intervals specimens of catalyst are withdrawn and analysed for carbon content.  From these data curves are drawn which show (a) a first period in which carbon deposition on catalyst is rapid (b) a second period during which deposition is substantially uniform (c) a third period in which the deposition becomes rapid; and from such curves for a specific stock the time at which the run should be terminated is calculated.
