Abstract: Abstract of the Disclosure The instrument disclosed herein is designed for measuring flow rates and densities of moving fluid streams, including liquids, gases, slurries, and fluids which contain solid materials.  In one embodiment of this instrument, a conduit section, which has a 90 degree bend therein, is placed in a transfer line which carries the fluid stream to its use point.  Defined within the conduit section is a chamber, which is located at the bend in the conduit.  Installed within the chamber is a force measuring transducer and a piston, which is is contact with the diaphragm assembly of the transducer.  In operation, a part of the moving fluid is diverted into the chamber, to equalize fluid pressure across the diaphragm assembly of the transducer and the piston.  This removes the effect of fluid pressure on the flow rate and density measurement, and allows the moving fluid to displace the piston by the force exerted by the fluid.  The transducer registers the force and transmits it to a computer, which converts it to a flow rate as a function of the force.  A separate transducer measures the velocity of the stream and this measurement is converted to a density value.

Abstract: ABSTRACT OF THE DISCLOSURE   The present invention is a multiprocessor machine control having at least one processor for performing input and output operations and communicating with a master processor over a communication channel. Common synchronizing signals are conveyed to both the input/output processor and the master processor independent of the Communication channel. This provides the input/output processor with immediate access to timing and synchronizing information for prompt response to general control information from the master processor. The master processor downloads instructions or provides general instructions to the input/output processor. These downloaded instructions are given priority and timely executed without further communi-cation with the master processor. At completion of the operation the master processor is informed that the particular operation has been performed.

Abstract: ABSTRACT OF THE DISCLOSURE         A slitter cuts flattened pieces of fibrous plant material into longitudinal strips.  The slitter comprises a pair of opposed rotary members each having a plurality of annular cutting teeth.  Each cutting tooth comprises an outer annular cutting edge, a radial rear race, and a non-radial front face.  The cutting teeth of the two rotary members overlap radially to engage opposite sides of a plant piece and completely cut through the plant piece and slit same into strips.  The teeth define cells in which the strips are rotated while being fed.  front faces of the cell are arranged opposite each other and spaced apart at the point of maximum overlap to define a cell width corresponding to the thickness of the plant piece to grip the sides of the respective strip and positively advance and discharge same.  In a modified embodiment, the teeth include replaceable cutting inserts which are removably attached to base members and extend radially there beyond.  This arrangement increases the amount of cutter overlap without reducing the size of the cells.  The inserts are attached to the base members by solder and are removed therefrom by melting the solder.
