Aluminium, obtaining. - The charge of an electric furnace for obtaining pure aluminium comprises a layer 14 of a relatively dense aluminium alloy constituting the anode, an intermediate layer 20 of fused fluorides, and an upper layer 21 of aluminium constituting the cathode. Refined aluminium is withdraw from time to time by a notch 26, provided with a refractory plug 26 and impoverished anode alloy is withdrawn by a tapping plug 29. Fresh alloy may be supplied through a carbon funnel let down into the anode layer. The furnace comprises a carbon base 13 having a bowllike cavity and enclosed together with a bottom heat-insulating layer 12 of bauxite in a steel shell 11. The shell 11 is provided with a water-cooled ring 19 surmounted by and insulated from a water cooled ring 18. An insulating refractory lining 17 is frozen on the shell walls by the cooled rings and an insulating refractory top, crust 22 which may be of both ingredients is formed above the cathode. The anode is connected to the positive supply conductor by a bus-bar 15 and distributor plates 16 and the cathode is connected to the negative supply conductor by graphite plates 23 and rods 24. The anode alloy may consist of aluminium and copper in the proportion of 60 to 40 and silicon up to 10 per cent. Iron though not advantageous may be present up to 10 per cent. The electrolyte preferably consists of aluminium fluoride 33 per cent, sodium fluoride 30 per cent, barium fluoride 35 per cent and alumina 2 per cent. The barium fluoride may be replaced wholly or in part by strontium fluoride. If alumina accumulates in the bath it may freeze on to the lining so as to choke the cell rendering it necessary to break away a portion of the lining and form a new one. To prevent this, a portion of the bath may be removed from time to time and replaced by material free from alumina. A pressure of 7 volts and current density between 900 and 1400, preferably 1200, amps per sq. foot of anode are employed, the working temperature being about 950 C. Aluminium containing not more than 0.15 per cent or even 0.1 per cent of impurities may be obtained, the impurities being iron silicon and copper. Such aluminium is said to be characterised by a high degree of softness, ductibilty, malleability and strength and by high resistance to attack by dilute hydrochloric and other acids. Its melting point is 659.5 + 0.3 C. Its specific resistance at 20 C. is 2.7 michroms per cur. cube. Its appearance is silvery and it retains its lustre for a long period. It is specially suitable for making collapsable tubes.

Title: Improvements in machines for weighing and filling powdered material into bags
IPC: B65B1/32
Filed: 1927-12-05
Abstract: 293,636. Andreas, A. Dec. 5, 1927. Filling powdered material into bags. - A machine for weighing and filling powdered material into automatically-closing valve bags is characterized by the weighing and the filling being accomplished by working operations which are independent of each other. The material within a supply hopper 1 is loosened by a continuously-rotating stirrer 2 and when the sliding feed gate 3 is drawn out, by hand, the material runs into a weighing receptacle 12 mounted on a beam 13. When the requisite weight has entered, one end of the beam knocks up a catch 9 and a spring 10 draws the feed gate into the closed position. The feed gate is pressed against its seating by weighted levers 6 carrying bell-crank levers 7 provided with rollers bearing against the feed gate. The weighing receptacle is retained in its lower position by a weighted catch 31. To discharge the receptacle, a power-driven friction disc 17 is thrown by hand-operation into gear with a worm 14 which -expels the weighed material through an orifice 15 whence it falls down a vertical filling pipe 16 termiating in a horizontal portion 18, Fig. 2, provided with an air vent 20. The horizontal portion 18 forms a support for the valve bag 19. Owing to the momentum acquired in falling down the filling pipe 16 the bag is filled without the necessity for shaking it. A modified filling pipe, Fig. 5, is provided with a chamber 31 to receive the displaced air. In a further modification the material is delivered to the bag through a short pipe containing a fan wheel to impart the desired velocity to the material. Two independent weighing-machines may be arranged to discharge into a common filling tube. In a modification, Fig. 7, the weighing receptacle 22 is arranged to be tipped by hand so as to discharge its contents into a fixed container 24 provided with a constantly-rotating worm 14 which expels the modification, Fig. 10, the material from a hopper material into the filling tube 16. In a further modification, Fig. 10, the material from a hopper 33 is deflected by a flap 35 into one or other of two shoots 34 and thence to a corresponding weighing receptacle 32. The weighing receptacles discharge into chambers containing worms 36 and the worms deliver to breeches shoots 42 controlled by flaps 37. Four filling pipes 38 - - 41 are provided and the flaps are operated so that the filling pipes receive the weighed charges in rotation. By slowing down the worms 36 and reducing the diameter of the filling pipes 38 - - 41 the bags are filled considerably slower thus avoiding formation of dust and allowing the material to settle without mechanical assistance.
