Title: Electrolytic apparatus including bipolar electrodes defining an enclosed volume and held in a nonconductive frame
IPC: C25B3/23
Filed: 1968-06-27
Abstract: An olefin, such as propylene, ethylene or butene, is converted to its oxide in an electrolytic cell comprising a bipolar electrode (see Division C7). In oxidizing propylene to propylene oxide in an electrolytic cell divided by a diaphragm into anode and cathode zones, the cell is filled with aqueous KCl solution and the propylene together with an inert gas, mainly propane, are introduced into an anode zone. Propylene chlorohydrin is formed and passes through the diaphragm to the cathode zone where it is dehydrohalogenated into propylene oxide. It leaves the cell partly in solution in the electrolyte and partly in gaseous form together with H 2 formed at the cathode. Some 1,2-dichloropropane is also formed.

Title: Method and apparatus for producing metallic arsenic
IPC: C22B30/04
Filed: 1968-11-09
Abstract: Crystalline arsenic is continuously produced by suspending arsenic trioxide in a stream of ammonia gas, heating the mixture to a temperature in the range 500-1000 C. to catalytically decompose the ammonia into nitrogen and hydrogen which latter reduces the oxide to arsenic and then condensing arsenic from the gas phase, e.g. at a temperature in the range 200 C-470 C. Preferably a 10-20% stoichiometric excess of ammonia is used. The arsenic oxide may be fed by metering means to a stream of pressurized ammonia, passed through quartz glass tubes or silica brick lined passages of a reactor heated by electrical resistances, the reacted gas being passed to a condenser in which glass, quartz or aluminium vertical rods or tubes provide the condenser surfaces, and then to a gas washer to remove residual arsenic from the gas phase.

Abstract: An electronic arrangement for generating, from a reference value proportional to the rate of movement, for example, from an a.c. voltage generated by a means of a tachometer generator, two a.c. voltages which can be shifted in phase with respect to each other by a constant frequency-independent amount. An arrangement is provided in which a variable input a.c. voltage is changed to a triangular voltage of constant amplitude and proportional in frequency to the a.c. voltage. There is a first square-wave voltage derived from the triangular voltage and the triangular voltage is inverted. The inverted and uninverted triangular voltage are each applied to one input of two comparators and a manually variable d.c. voltage is applied to the second input of each comparator. The d.c. voltage is manually variable between the maximum and minimum amplitudes of the triangular voltage. The outputs of the two comparators are connected to a bistable multivibrator which generates a second square-wave voltage shiftable in phase by the angle psi with respect to the first square-wave voltage by varying the d.c. voltage.
