Title: Improvements in flax pulling machines
IPC: A01D45/06
Filed: 1923-01-23
Abstract: 192,385. Pusch, E. Jan. 23, 1923. Flax-pulling machines. - A flax-pulling machine is provided with a number of pairs of cooperating belts between which the upper parts of the flaxplants are gripped, the lower p a r t s being simultaneously engaged by a rotating roller on the machine. The belts 12 are mounted in a frame L and have grasping devices mounted on chains 14 which pass round sprocket-wheels driven from a countershaft 11 itself driven from the main supporting wheel E of the machine. The grasping devices comprise a number of elements each consisting of a U-shaped sheet metal frame 46, Fig. 10, recessed to receive a resilient rubber facing 47 and flitting over a U-shaped metallic back-piece 49. The backpieces 49 bear against track members 27 thus pressing the opposing rubber facings towards one another and gripping the flax. The plants are directed to the gripping members by dividers 60. A bar or roller 13, mounted on the lower part of the machine, engages the flax stems as the plants are gripped by the belts and assists in pulling them from the ground. The roller 13 is preferably rotated to effect a lifting action on the plants by chain-and-sprocket connections with the shaft 11. A reel carrying rakes 29 is supported from a frame N carried by the frame L. The rakes are carried on heads pivoted in the arms 36 of the rotating reel and provided with cranks 39 that are connected by bars 38. Rollers 64 on one of the members of the frame engage the bars 38 and maintain the rakes in operative position as they sweep through the flax. The frames L, N are vertically adjustable on the struts H, J of the main frame being suspended by cables 56, 57 which may be wound up by operating a drum 53. Inclined guides 30 are arranged below the gripping devices, and, as the plants fall on being released, these guides direct them to a conveyer M which carries them to a binder.

Title: Improvements in or relating to production of denser graphite
Inventor: GREENHALGH GEOFFREY HARVEY
IPC: C04B35/532
Filed: 1952-01-25
Abstract: Artificial graphite is prepared by heating calcined carbonaceous material substantially free from sulphur, nitrogen and oxygen to a graphitizing temperature.  Suitable carbonaceous material may be obtained by coking a petroleum fraction, other than a high-boiling fraction or a residue, or as by-products in the thermal reforming of petroleum distillates giving rise to a polymerized residue, which may be processed to coke.  In the example the residue from the thermal reforming of a gasoline fraction is coked, and the resulting coke is calcined at 1000 DEG  C. to reduce the volatile content below 1 per cent, ground, and mixed with a coal tar pitch binder.  The resulting plastic mass is moulded, or extruded to electrode shape, and the resulting shapes are baked in a ring furnace up to 1200 DEG  C., and graphitized at 2200-2700 DEG  C.
