Abstract: The quantity of a flow of bulk material passing over a measuring wheel is continuously measured by measuring the load r.p.m. of the wheel or of a motor driving the wheel and the power output torque of the motor. The resulting r.p.m. and torque values are used for calculating the quantity. Interfering influences are substantially eliminated by using a correction value in the calculation. The correction value is based on the inertia moment of all rotating components of the system and on variations in the load r.p.m. Load r.p.m. and power output torque measuring devices provide data to a microprocessor for the calculations for achieving a high measuring precision even when the r.p.m. varies.

Abstract: The invention is directed to an overcurrent-protective switch for household appliances such as a vacuum cleaner. The snap switch has a housing in which a contact mounting unit is mounted at one end of the housing and contains one of two current terminals of the switch. The other current terminal is mounted at the other end of the housing and is configured to define a contact-engaging surface. A resilient interrupting contact member is fixedly connected to the one current terminal and has a metal center strip by means of which it is held in one of two end positions. In the first end position, the contact member is held in contact engagement with the contact-engaging surface of the other current contact terminal and, in the second end position, it is disengaged from the contact-engaging surface. When the center resistance strip is cool, the contact member is in its first position and the current circuit between the two current terminals is closed. On the other hand, when excessive current passes through the center strip, the latter heats and expands causing the contact member to snap over into the second position to interrupt the current circuit between the two current terminals. A reset plunger returns the contact member to its first position.
