A hand blender powered by an electric motor, for mixing or comminuting foodstuffs in a container, includes a working shaft having an output end, a processing tool attached to the output end of the working shaft, a shaft housing which carries the working shaft, and a bell-shaped casing enclosing the processing tool. The bell-shaped casing has a lower chamber, a lower end bounded by an aperture, and a plurality of lateral openings for the discharge of foodstuffs. A cover plate within the bell-shaped casing forms a fluid-tight seal between the lower chamber and an inner chamber of the shaft housing. The hand blender also includes an air supply structure through which outside air is supplied to the lower chamber of the bell-shaped casing when the bell-shaped casing is immersed in the foodstuffs. The air supply structure includes a flow channel with an inlet side which communicates with the outside air and an outlet side which communicates with the lower chamber of the bell-shaped casing.

A hair styling device includes a hair roller that defines a conical inner chamber open at its larger end and has a jacket containing a heat storing material, a cooperating heating spindle for heating the hair roller, the heating spindle having a conical outer surface matching the inner surface of the inner chamber of the hair roller, and biasing means for causing the hair roller to rise off the heating spindle. Hair roller holding means comprises a body of ferromagnetic material carried by the hair roller adjacent the smaller end of the conical chamber and a magnet, the body of ferromagentic material being movable into the holding range of the magnet when the hair roller is placed on the heating spindle to hold the conical surfaces of the chamber of the hair roller and the heating spindle in mating engagement. The Curie temperature of the ferromagnetic material corresponds to the set temperature of the hair roller, so that when the hair roller is heated to its set temperature, the holding force of the magnet is reduced and the biasing means lifts the hair roller off the heating spindle.

A hair curler for rolling up the hair having a cylindrical rod body containing a catalytic heating device. The rod body is permanently affixed on a handle which is designed as a fuel tank. A thermostatically controlled valve device, between the fuel tank and the rod body, regulates the fuel supply from the fuel tank to the catalytic heating device. An opening allows air to enter the chamber which contains the catalyst. An ignition device is situated at the free end of the cylindrical rod body. The ignition device is activated by means of an operating key which closes an electrical circuit, to heat an incandescent filament, and thus to initiate catalytic combustion at the catalyst. A chamber is situated between the battery and the combustion chamber. This chamber is flushed through by ambient air and inhibits heat flow. The electrical conductors of the ignition device are conducted through this chamber.
