Abstract: A system for measuring particulate discharge from a vehicular internal combustion engine has a dilution tunnel into which exhaust gases are introduced and mixed with and diluted by clean air. A part of the diluted gases is introduced through a sampling probe into a sampled gas line in which a filter is provided to collect particulates contained in the sampled gases. A differential pressure transducer is provided to detect the pressure drop across the filter and convert the detected pressure drop into an electric signal which is fed into an operator which is operative to compute the quantity of particulate content of the engine exhaust gases on the basis of the time differential of the electric signal from the differential pressure transducer.

Abstract: In an electrostatic reproduction machine there is provided one or more rollers capable of rotating in union with a copy sheet being advanced, in the course of travel of the copy sheet. Sensing switches are provided for sensing nonuniformity in rotation of the rollers which may occur in abnormal copy sheet transportation states and, more particularly, in a jam state. The outputs from the sensing switches are utilized for identifying the abnormal machine states.

Abstract: In a selective calling circuit including a band-pass filter which may be constituted by an active filter, and a power source for energizing the filter, a control signal is generated which has a predetermined duration in accordance with the output of the band-pass filter at a point of time whereat the output of the band-pass filter reaches a predetermined level. In response to the control signal, there is established a state in which the center frequency of the band-pass filter can be changed, and the output of the power source is changed from a first level to a second level for a period of time substantially corresponding to the predetermined duration of the control signal. At the aforementioned first level, the band-pass filter may be energized, while at the second level, it may be deenergized.
