Title: An improved process for preparing metals and alloys from metallic compounds
IPC: C22B4/08
Filed: 1932-06-20
Abstract: Metals and alloys are obtained by dissociation of metal compounds by passing the compounds in finely divided condition at atmospheric or super-atmospheric pressure through one or more electric arcs, the products being cooled or quenched immediately on emerging from the arc or arcs.  In some cases the arcs may be enlarged or deformed by magnetic means.  An additional gas may be present which is capable of reacting with the free non-metallic constituent of the compound, and such gas may also be passed through one or more arcs.  The separation of the metals from the products may be effected by passing the mixture through an electrostatic field.  In an example, aluminium chloride is treated for the production of aluminium, hydrogen being present to combine with the chlorine.

The power-absorbers 51, 44 are adjustable to simulate resistance to vehicle propulsion and vehicle steering respectively, when the mechanism 12 is driven from a source of power 11, which may be an electric motor, internal combustion engine or gas turbine with a control 11'. Flywheels 51', 48 simulate the inertia of the vehicle to propulsion and turning respectively. The effect of gravity on downhill operation can be simulated by arranging for the device 52 to deliver power and the device 11 to absorb power. A ratio control 12' may be set for the straight ahead driving condition to provide equal inputs to the gears 10a, 10b so that shaft 35 remains stationary and the absorber 44 does not function. The control 12' may be set for the pivot steer condition to provide equal and opposite inputs to the gears 10a, 10b so that shaft 31 remains stationary and only absorber 44 functions. The control 12' may be set for left or right steer to provide unequal inputs to the gears 10a, 10b and consequently rotation of both shafts 31, 35 at proportional speeds corresponding to the ratio set so that both absorbers 52, 44 rotate and must be suitably adjusted according to data recorded in field tests. The apparatus allows transmission mechanism to be tested without mounting it in a vehicle.
