Abstract: A flow rate monitor for indicating the amount of material being displaced in a displacement system having an electric motor as a prime mover, comprises a power demand monitor for being operably connected to the electric motor; a programmable controller operably connected to the power demand monitor, the controller being adapted to convert the data from the power demand monitor to flow rate data using at least one linear equation relating the power demand of the electric motor to the flow rate of the material, the programmable controller being adapted to parallel shift the at least one linear equation to compensate for any changes to the no-load power demand; and an indicator for indicating the flow rate of the material.

Abstract: A device for controlling load on a first motor whose load is affected by a second motor, comprises a controller having a first input for being connected to a horsepower transducer connected to the first motor being monitored and an output for being connected to the second motor; and a program configured to receive the first input and generate the output responsive to the input.

Abstract: Apparatus and method apparatus for detecting marginal gradation changes of a controlled product on a conveyor. The apparatus comprises a transducer (4) for converting swinging motion to a number of pulses; a member (24) operably secured to the transducer, the member for being in contact with the controlled product to cause the member to swing back and forth, thereby causing the transducer to generate the number of pulses; and a programmable device (28) operably connected to the transducer, the device being adapted to count the number of pulses generated by the transducer over several blocks of time periods, compare the number in each block of time to a group of reference numbers for the product, sum the number of occurrences that the number is above or below the group of reference numbers and provide an indication when the sum exceeds a target value.

Abstract: A system for sensing the surface level of flowable material within a container, comprises a drop weight secured to a cable through a pulley for being disposed above the material and brought into contact with the surface level of the material. The cable is wound and anchored to a spool driven by a reversible motor. A transducer operably secured to the pulley provides an output responsive to the strain on the cable exerted by drop weight. A signal processor connected to the transducer generates an output signal responsive to the drop weight being supported by the material. A pulse generator for generating a plurality of pulses the number of which is proportional to the amount of rotation of the spool.

Abstract: An apparatus for precipitating particles, debris and the like from a gaseous stream, comprises an enclosed vessel partly filled with a liquid to a level and having a bottom wall; a passageway operably associated with the vessel for admitting the gaseous stream laden with particles into the vessel; an outlet operably associated with the vessel disposed above the liquid level for exhausting the gaseous stream; an atomizer disposed below the liquid level and operably associated with an end portion of the passageway for breaking up the gaseous stream into a multitude of bubbles. The atomizer includes a top wall and a depending side wall and a plurality of openings disposed in one of the walls adapted to break up the gaseous stream into the multitude of bubbles, thereby to promote substantial surface area contact between the particles and the liquid and cause precipitation of the particles from the gaseous stream onto the bottom wall of the vessel.
