Abstract: REMOTE AGENT OPERATION FOR AUTOMATIC CALL DISTRIBUTORS          Abstract This invention relates to an automatic call distributor (ACD) arrangement for economically providing ACD service from remote ACD agents. A remote ACD agent position is located near a local switching system which connects to an ACD host switch via a telecommunication network comprising a common channel signalling facility.  The remote ACD agent position and an ACD process at the host switch communicate with each other by sending data messages via the common channel signalling facility and the local switching system.  A front-end process at the host switch acts as a data message interface between the remote ACD agent position and the ACD process by performing protocol conversion between the common channel signalling facility message format and the ACD process message format. The front-end process also establishes a voice connection between the host switch and the remote ACD agent position.  The ACD process connects incoming customer calls to the remote ACD agent position for servicing of the call by the remote ACD agent. Advantageously, this arrangement permits the complex ACD software to treat remote and local agent positions alike and uses an economic communication arrangement for connecting the remote agent position to the host switch.

IPC: F16K11/00
Filed: 1990-02-07
Abstract: Abstract A bypass/diverter valve for controlling the flow of fluid from a source to a fluid treatment device such as a water softener.  The valve includes a valve housing defining a circular chamber having a cylindrical wall into which three spaced ports open into.  Two of the ports form inlet/outlet ports communicating with connecting conduits.  The third port forms an intermediate port that communicates with the input to the water softener.  The valve housing also defines a second intermediate port communicating with the output of the water softener and which communicates with the valve chamber though a passage arrangement.  A plug-like valving member is rotatable within the chamber and includes a recess which together with the chamber wall defines a passage for selectively communicating one of said inlet/outlet ports with said first intermediate port while concurrently communicating said other inlet/outlet port with the second intermediate port or alternately for communicating said first inlet/outlet port with said second intermediate port while concur-rently communicating the second inlet/outlet port with said first intermediate port.  The valving member is also positionable to block flow out of either of said inlet/outlet ports.  The plug member includes a recess for communicating fluid from the passage to one of the inlet/outlet ports when the valving member is rotated to a predetermined position.  A movement control disc delimits the extremes of movement in the valving member and is positionable in two different positions to change the extremes of movement.

Title: Non-dispersive infrared gas analyzer system
Inventor: TURY EDWARD L
IPC: G01N21/35
Filed: 1990-06-08
Abstract: ABSTRACT OF THE DISCLOSURE         A non-dispersive infrared gas analyzer especially adapted for measuring the concentrations of HC, CO and CO2 in a vehicle exhaust includes a sample chamber for holding a sample gas, a radiation emitter for directing a beam through the chamber and a detector for indicating the amount of radiation absorbed.  A plurality of filters each of which transmit radiation at an absorption band of a gas component to be detected are alternatingly positioned in the radiation path to produce a time-multiplexed signal having concentration information for all gases.  A calibration assembly is provided which includes a plurality of calibration cells selectively positionable in the radiation path in order to provide an internal calibration standard for two-point calibration of each gas channel.  The cells contain one or more of the gas components to be measured at concentrations and pressures predetermined to compensate for the difference in optical path length between the calibration cells and the sample chamber.  A technique is provided for characterizing the calibration cells in situ after a conventional calibration using bottled calibration gas is performed.  The time-multiplexed detector output is corrected for gain and offset errors "on-the-fly" without requiring demultiplexing through the use of an analog multiplier circuit.  The correction factors are themselves determined without demultiplexing the detector output signal.  The unit includes improved packaging in which the sample chamber is an easily cleaned, simple tubular member having opened opposite ends that are closed in use by transparent surfaces of source and receiver modules.  The entire functional assembly of the receiver module is attached to an access cover which is readily removable for replacement of failed calibration cells.

IPC: H02J7/04
Filed: 1990-07-04
Abstract: A battery charger for a portable wireless telephone set comprising a rapidly charging circuit for rapidly charging the battery by a first charging current of a high level at a start of the charging operation, a tricklingly charging circuit for tricklingly charging the battery by a second charging current of a considerably low level, and a charge controller for making the tricklingly charging circuit take over the rapidly charging circuit after a charge detecting circuit detects that the battery is rapidly charged to its normal voltage. In order to avoid that the battery is insufficiently charged by the tricklingly charging circuit when the telephone set is left in a power-on condition, the battery charger further comprises another charging circuit for supplying a third charging current which is lower than the first charging current but higher than the second charging current.  When the telephone set is in the power-on condition, the charge controller operates not the tricklingly charging circuit but the other charging circuit after the battery is rapidly charged to its normal voltage, so that the battery can be charged to the normal voltage even if the telephone set is left in the power-on condition.
