Abstract: The thrusters or the rams for pressing the metered amounts of product into the metering seats are equipped with force transducers which emit an electrical signal proportional to the thrust exerted during the pressing step. This signal is transmitted to the processor for controlling the operation of the packaging machine, which compares the signal with predefined reference values, in order to check whether or not the weight of the metered amounts lies within acceptable values. If it does not, the processor causes expulsion, from the unloading flow of the full capsules, of those capsules with metered amounts which have an unacceptable weight and which, if necessary, may be weighed using a precision device connected to the processor which may use this signal to confirm the operation of the transducers or correct it automatically.

Abstract: A zero turning radius power lawn mower for operation by a standing occupant includes first and second independently driven and controlled rear drive wheels mounted on separate drive axles. A riding platform for supporting the standing occupant or operator is located between the first and second rear drive wheels. The rear drive wheels are independently driveable in both the forward and reverse directions at variable speeds so as to allow for substantially zero radius turning of the mower about a central turning point.
