Abstract: An automatic monitoring system for the constant current source in a balance having electromagnetic load compensation includes circuitry which generates a first current varying in dependence on the constant current and furnishes a digital signal indicative of the value of that current. A microcomputer is provided to compare the digital value to a reference value. If the comparison indicates that the constant current is outside of a given range of values, the microcomputer energizes the display to indicate the presence of an error.

Abstract: A band carrying a series of labels separated by gaps is transported step by step past a location at which individual labels are removed and automatically applied to boxes, etc. Along the path of the band, at a scanning station, a backing plate is provided on the empty side of the band, while the side with the labels is scanned by a device which consists of a feeler roller eccentrically mounted on an angle lever. As the roller drops into the gap between labels, the lever pivots, carrying along with it a bar whose opposite end normally interrupts the flow of air in an air cell. The rotation frees the air cell causing generation of a signal designed to stop the transport of the band. To allow for the relatively long response time of the cell, the bar is rotatably mounted on the lever and continues its motion due to inertia after the lever itself has stopped and even after it has reversed direction as the roller moves onto the next label.

Abstract: A method and an apparatus for (a) monitoring fluid flow by transmitting acoustic signals in opposite directions through a fluid with components in the direction of flow; (b) receiving the transmitted signals; (c) providing a first signal representing acoustic velocity; (d) time-integrating the first signal to produce a ramp signal, the rate of change of which represents acoustic velocity in the fluid; (e) transmitting a first acoustic signal in one direction through a fluid; (f) transmitting a second acoustic signal in the opposite direction through the fluid; and (g) initiating integration of the first signal. The ramp signal is compared with a second signal representing fluid flow velocity to generate first and second arrival signals according to the direction of the transmitted acoustic signal; expected arrival times for the transmitted acoustic signals are compared with the actual arrival times of the transmitted acoustic signals, and the results of the comparisons are stored.
