Dosier- und Mischgeraet fuer die Mischungsbestandteile von Zahnfuellungen

摘要

A mixer for dental fillings having a reciprocating, oscillating or vibrating container such as is described in Specification 975174 has a roller (24) with metering pockets (24a) secured to a shaft on which are fixed also a knob (25) and a wheel (51) with notch (50) into which can enter the end of the core (52) of a solenoid (53). The solenoid is connected in parallel to the motor which oscillates the mixing container, and both are controlled by a common time switch. The knob (25) can therefore be rotated to discharge materials into the mixer only when the motor is operating.
