Abstract: A device for removing hair from hairbrushes having a housing with an inlet opening and a suction outlet connectable to a suction device. A Deflector device is arranged between the inlet opening and suction outlet in such a way that it blocks direct passage from the inlet opening to the suction outlet, and which forms a friction surface. Hair makes contact with the friction surface when sucked into the device. By pulling the brush away from the device, hair may then be pulled out of the brush.

Abstract: In a load-shifting device, a switch arm (7) is mounted on a driven shaft (3) and is turnable relative to the driven shaft (3) and urged in the direction of a switch contact (9) by a spring (8) which is wound around the driven shaft (3). The spring (8) is developed as an electric conductor. On one leg (13) it has a connecting piece (20) while its other leg (11) directly contacts the switch contact (9).

Abstract: A process for the purification of pressurized gases, such as those emanating from the partial gasification resp. combustion of fuel, which gases contain Ni(CO).sub.4, which comprises contacting said Ni(O).sub.4 containing gas with a solvent at a temperature of from -60 to 0.degree. C., thereby forming a solution containing the gases and dissolved Ni(CO).sub.4, and thereafter heating said solution at a temperature of from 70 to 250.degree. C. for at least 0.25 hour at a pressure higher than the vapor pressure of said solvent, thereby precipitating and thereafter recovering nickel compound and releasing a purified solvent.
