Abstract: CALL COVERAGE ARRANGEMENT Abstract A call coverage arrangement in a telephone system. Any station served by the system may be assigned to a call coverage group as a principal station.  A coverage group includes the identities of a plurality of call covering stations for the principal station and an indication of the order of preference of the covering stations.  Call coverage criteria are stored for principal stations specifying circumstances under which calls intended for the principal stations are redirected to coverage.  A covered call is redirected sequentially to each of the covering stations in a coverage group in the order of preference until the call is answered or abandoned.  The coverage criteria includes options based on both the state of a principal's station (active, busy, idle, etc.) and the class of an incoming call (internal, external, priority). Principal stations are equipped with a "send all calls" button.  The button may be operated while a call is arriving to redirect the call without waiting for automatic coverage to take effect.  To give a caller control over the disposition of a call scheduled for coverage, the caller is alerted at the time a coverage criterion is satisfied that the call is scheduled for coverage.  Thereafter, a short time interval is provided during which the caller may abandon, activate the automatic generation and storage of a callback message or wait for the call to be redirected to coverage.

Title: Method of producing an extrudate having controlled  shape and size

IPC: B29C48/92

Granted: 1984-07-17
Abstract: METHOD OF PRODUCING AN EXTRUDATE HAVING CONTROLLED SHAPE AND SIZE     ABSTRACT OF THE DISCLOSURE     A method of producing an extrudate is disclosed in which on-line adjustments are made to size and shape devia-tions by varying the temperature conditions in the extruder and by varying the relative speeds along the extrusion line.          The temperature conditions can be adjusted by varying the temperature of the stock while maintaining a fixed relation-ship of the die temperature to the stock temperature to pro-duce deviations in the thickness of the extrudate with respect to the width of the extrudate, and by varying the temperature of the die with respect to the temperature in the stock to produce variations in different thicknesses of the extrudate.  The relative speeds along the extrusion line can be varied by changing the speed of the screw in a cold-feed extruder, by changing the feed rate for a hot-feed extruder, or by changing the speed of the take-away device which regu-lates the speed by which the extrudate is taken away from the extruder.

Abstract: "Method for treating blast furnace gas and apparatus for carrying out that method"     ABSTRACT OF THE DISCLOSURE     Blast furnace gas containing dust particles has the coarsest particles removed and the result wet scrubbed before being fed to a treatment apparatus for separating the remaining coarse dust, which has a low lead and zinc concentration.  The gas dust is fed to a separator in the form of a thickener where coarse particles are removed through an outlet whilst the remaining gas dust is fed to a settling basin.  This concentrates the dust particles before they are fed via pipe to a second separator having two hydrocyclones.  Here the coarse particles are removed via pipe.  The coarse particles from the outlet and pipe are suitable for feeding to a blast furnace as they are low in lead and zinc.  The presence of the settling basin gives a more distinct separation if the dust particles by the hydrocyclones and the hydrocyclones can operate more efficiently.

Abstract: CONSTANT-CURRENT DUTY-CYCLE DRIVER    FOR ELECTROMAGNETIC FLOWMETER                    Inventor:  Roy F. Schmoock, a citizen of the United States of America and resident of Yardley, Pa.                      ABSTRACT            A driver for the excitation coil in the electromagnet of an electromagnetic flowmeter, wherein the fluid to be metered is conducted through a flow tube to intersect the transverse magnetic flux field created by the electromagnet.  The driver includes an a-c line rectifier whose output is coupled to the coil by a pair of switching transistors, the control electrodes of which are connected to the output of a comparator having first and second input terminals.  Applied to the first terminal of the comparator is an alternating square wave voltage, each cycle of which has a positive and a negative gating pulse whereby the transistors are alternately actuated, the arrangement being such that the rectified output is applied by the transistors to the coil with a polarity which is alternately reversed.  The comparator includes a positive feedback loop connected between its output and the first terminal to produce a pulsatory output whereby during each negative and positive gating interval, the coil is excited by a train of pulses.  The duty cycle of these pulses is varied as a function of a reference voltage derived from the current flowing through the coil and applied to the second input terminal, thereby regulating current flow through the coil to maintain a substantially constant current level.

Abstract: ABSTRACT OF THE DISCLOSURE          An operation control method for a nuclear reactor performing a load follow-up operation in accordance with a load variation program, wherein a core reactivity which changes with time in a first cycle of operation is predicted based on the load variation program and data for analyzing dynamic characteristics of the reactor, and a change in a liquid poison concentration in the first cycle of operation is obtained based on the predicted reactivity, and reactor power is controlled in the first cycle of operation by adjusting the liquid poison concentration in accordance with the obtained change.  When the liquid poison concentra-tion is adjusted and control rods are manipulated, a reactivity introduced by these operations in the first cycle of operation is obtained, and an adjustment to be made to the liquid poison concentration in the second cycle of operation which is the next cycle of operation following the first cycle of operation is obtained from the reactivity introduced in the first cycle of operation.  When the change in reactivity in the second cycle of operation becomes equal to that in the first cycle of operation, and reactor power is controlled in the second cycle of operation by performing the obtained adjustment of the liquid poison concentration.
