Title: An improved process for the destructive hydrogenation of carbonaceous materials
Filed: 1930-09-22
Abstract: Heavy hydrocarbon material, such as heavy oils to which coal or asphalt may be added, is destructively hydrogenated in a primary reaction zone, vapour from which is partially condensed, e.g. at above 400-600 DEG  F., under rectifying conditions and the same pressure, part of or all the condensate being returned to the primary reaction zone and the uncondensed vapour being subjected to destructive hydrogenation in a secondary reaction zone.  The fraction condensed from the primary reaction chamber may lie between 550 DEG and 600 DEG  F. and from the remaining vapour a fraction boiling above 400 DEG  F. may be condensed.  The temperature of the second reaction chamber is maintained above that of the primary reaction zone, the upper limit of the temperature in the first being 900 DEG F. and the lower limit in the second being 850 DEG  F. Pressure in the primary zone is above 100 atmospheres and in the secondary between 20 and 100 atmospheres.  Catalytic material is provided in the secondary treatment, e.g. mixtures of molybdenum and zinc oxides, tungstic acid and magnesia, chromic and molybdenum oxides with or without zinc and magnesium oxides. Heavy oil, which may contain coal, is fed by a pipe 11 through a cooling coil 13 in a fractionating column 9 and a pipe 14 to a heating coil 1 whence it passes to an insulated pressure reaction vessel 3, the temperature of which <PICT:0359661/III/1> is maintained by electric heaters or by withdrawing part of the charge through a pipe 4 and circulating it through the coil 1. Hydrogen is supplied by a line 7 through the coil 1 or directly to the vessel 3 by a pipe 6.  Gas and vapours pass by a pipe 8 to the fractionating column 9.  Instead of passing the oil through the coil 13 it may be byepassed and led by pipes 11<1>, 14<1> into the fractionating column 9 below a plate 15 which allows the passage of vapour but prevents return of the reflux.  Preferably the oil passes first through the coil 13 before entering the column 9. Condensate and oil from the lower part of the column 9 may be fed directly to the reaction chamber 3 or by a pipe 18 to the pump 5. Condensate on the plate 15 passes to a cooler 16 and a separator 17 and thence to storage, the gas being collected. Vapours from the column 13 pass by a pipe 20 and a pressure release valve 21 to a second vapour phase treatment with hydrogen in an electrically heated vessel 22 containing catalytic material 22a.  Alternatively, the vessel 22 is heated by hydrogen forced through a coil in a furnace 24 and a pipe 25 into the pipe 20. The resultant gases and vapours pass through a condenser 27 and a separator 28 from which the gases pass through a purifier 30 where sulphur and hydrocarbons are removed. From the purifier, the gas passes by a pump 29<1>, a pipe 31 and a pump 32 to pipe 31<1> or pipe 7.  The pressure in the primary reaction chamber is above 20 atmospheres, preferably above 100 or 200, and in the secondary reaction chamber between 20 and 100 atmospheres.

Title: Improvements in methods of forging railway axles
IPC: B21K1/06
Filed: 1953-10-19
Abstract: 772,724. Forging railway vehicle axles. HOOD, B. E., and HOOD, T. A. Oct. 18, 1954 [Oct. 19, 1953], No. 28783/53. Class 83 (2). A method of forging railway vehicle axles consists of a sequence of forging operations whereby a hot billet is successively reduced and shaped on a hydraulic press or presses in successive sets of dies of which the final set is of closed form to impart the desired finish-forged shape to the axle, the billet being initially of greater diameter and less length than the axle but approximating in weight thereto. A hot billet 6, Fig. 1 (not shown), is first subjected to two squeezing operations in open-ended dies whereby its diameter is reduced. In a second operation the workpiece is subjected to a plurality of squeezes whilst being rotated in the die, whereby the body part 7, Fig. 2, is reduced in diameter. In a third operation, the body 7 and the seats 8 for receiving the wheels are formed in one operation in closed dies. In a fourth operation, Fig. 3, the ends 9 are reduced in diameter in three or four squeezes in open-ended dies. In a fifth operation, Fig. 4, the journals 10 are forged in closed dies. In a sixth and final operation the workpiece is forged to its final desired form, Fig. 5 (not shown), in two squeezes. For rotating the axle between squeezes, it is raised by one or more ejectors, each consisting of a small hydraulic ram, whilst a manipulator clamps on to the axle and rotates it as necessary. When a single hydraulic press is used the dies are mounted in a movable die housing whereby they are brought successively under the vertical centre line of the press for the forging operation. Alternatively a plurality of hydraulic presses each having a pair of dies, may be used. The final forged axle is machined to its required form where necessary. This machining may consist of cylindrical grinding only.
