Abstract: ABSTRACT For forming ? bi. ci, in a pulse width multiplier, two input vol-tages bi are summed at the input of an inverter and are added, after each passes through a separate switch and proportional stage, at the input of a smoothing stage, to the inverter output signal.  The switches are actuated by switching pulses which are width-modulated in accordance with the factors ci.  The calculated sum is present at the output of the smoothing stage. Great accuracy in field-oriented control of rotating-field machines is possible when vector analyzers and vector rotators designed in this manner are used.

Abstract: ABSTRACT OF THE DISCLOSURE           A paper machine screening apparatus generally includes a centrifugal pump member mounted for rotation about the axis of a tubular screen plate.  A delivery passageway extends concentrically about the pump impeller for receiving pumped stock flow and includes an annular axially extending passage formed between a ribbed hub surface of the pump and the screen.  Flow through the screen is passed from the screening apparatus to headboxes. Downstream of the annular passage is an end cavity for receiving particles unable to pass through the screen holes which are wahsed into the end cavity by the axial flow through the annular passage.  The ribbings on the hub surface serve to agitate the stock flow to raise pressure forces tending to force flow out through the screen holes.

Abstract: ABSTRACT OF THE DISCLOSURE         An autozero loop for eliminating offsets in the analog to digital converter section of a voice frequency coder-decoder (CODEC) utilizing an array of capacitors and a linear resistor string.  The autozero loop functions with a relatively small time constant to null offsets quickly during the power-up phase of CODEC operation and with a higher time constant after the power up phase.  A dual bandwidth sub-circuit in the loop is connected to a voltage generator and controlled by signals from a logic circuit to operate at different bandwidths and thus provide different off-set cancelling feedback signals during the power-up and normal operating phases.

Abstract: ABSTRACT    A remote and control system wherein a plurality of remote sensing units are connected to a central control and monitoring console by only four interconnecting wires.  A clock signal is converted to a plurality of parallel address signals at the local monitoring console and also at the remote sensing units located up the building.   A sync signal is employed to synchronize all of the serial to parallel converters in the system, and each remote unit is provided with a specific code and is identified by selectively routing one or more signals through an invertor located at each unit so that the signals trigger a logic device in the particular time slot assigned to each remote unit.  The input circuitry of each remote sensing unit compares two fixed microvolt reference signals derived from the least significant bil of the address signals with the return signal from the sensing device to sense for opens, grounds, normal conditions, and alarms.  The system is adapted to operate with conventional computing means and programmable read only memories, as well as a mutiplexer unit, for providing control signals to operate controlling devices upon the occurrence of predetermined signals from the sensing device.
