The telephone communication system has at least one telephone line (801-805) adapted for carrying incoming telephone calls, and a plurality of station sets (231-235), including an attendant station set (231) for forwarding incoming telephone calls, and a plurality of adjunct station sets (232-235) each adapted for receiving incoming telephone calls. The attendant station set is coupled to the plurality of adjunct station sets. The information processing system includes a caller identification signal receiver (252), a timed switching device (254), and a call forwarding device (250). The timed switching device (254) is coupled between the incoming telephone line (801-805) and the call forwarding device (250). The call forwarding device is coupled between the timed switching device (254) and the plurality of station sets (231-235). The caller identification signal receiver (252) is coupled to the incoming telephone line (801-805) and the call forwarding device (250). When no incoming call is being received, the timed switching device (254) is in a first, open state, such that a circuit between the telephone line and the call forwarding device is interrupted. Upon receipt of an incoming call on the telephone line, the timed switching device and the caller identification signal receiver are activated. The timed switching device enters a second, closed state after a finite amount of time has elapsed such as, for example, several seconds, thereby allowing sufficient time for the caller identification signal to arrive on the incoming telephone line. The caller identification signal receiver responds to the receipt of incoming caller identification information by immediately activiating the timed switching device, placing the timed switching device into the second state. In response thereto, the call forwarding device connects the incoming telephone call to a selected one of the plurality of said station sets.

Abstract: A system and method for controlling access to shared resources in a distributed computer system. Access to shared resources is controlled by a local authorization token manager. Only computer processes holding authorization tokens for the requested operation may perform that operation. Each requested operation checks for the proper token. If the token is not held by the process, it is requested. The local token manager resolves token conflicts before granting tokens. A token manager of a distributed file system export protocol also is able to request authorization tokens from the local token manager. The export protocol token manager controls authorization tokens for that particular distributed file system protocol. Multiple different export protocols may request tokens from the local token manager. The shared resources may therefore be shared by multiple different export protocols without conflict. Local processes and processes requesting shared resource operations through an export protocol that does not itself manage tokens are granted tokens through the operation token request mechanism. This mechanism enables local processes to use shared resources without the performance penalty of having to request through a local distributed client process.

Abstract: An attenuating, phase-shift, semiconductor fabrication mask having recessed attenuating and phase-shifting regions that is not susceptible to phase defects in the printing regions of the mask. This desirable result is accomplished by not altering the surface of the fully transmissive regions of the mask and by recessing the attenuating regions of the mask relative to the fully transmissive regions. A method of forming the recessed attenuated phase-shift mask is also included. The process begins by forming recesses in the regions of the mask substrate where phase-shifting is desired and back filling these recessed regions with a selected thickness of attenuating material so that the attenuation effect of the deposited material together with the depth of the recess co-act to shift the light approximately 180° (Π radians) from the light transmitted through the adjacent transmissive regions of the mask to create by destructive interference a sharp delineation at the edges of the projected mask image.

Abstract: A rotary actuator has a ferromagnetic armature with at least one arcuate-shaped wall extending circumferentially at the perimeter of the armature. The stator has a pair of axially and circumferentially aligned axial walls, separated by an axial air gap, disposed radially outward of, and in relatively circumferentially advanced relationship to, each such arcuate-shaped wall. Current flow in an electromagnetic coil associated with the stator causes magnetic flux to pass from one axial wall of each pair, across an air gap, to the respective arcuate-shaped armature wall, through that wall, and across a radial air gap to the other axial wall of each pair. Each arcuate-shaped wall has a ferromagnetic characteristic that causes it to be positioned to increasingly circumferentially overlap the respective pair of axial walls as the magnetic flux increases. The actuator may include a rotary flow control valve, such as an EGR valve for an automotive engine.

Abstract: A digital filter (20, 30) separates an M-bit (12) chrominance component (C12) from an N-bit (8) digital composite video signal (CV) supplied thereto, M (12) being greater than N (8) due to arithmetic operations (24,44,46,50) required for the separation. The separated M bit chrominance component is reduced to N-bits and subtracted from the composite video signal to provide a separated luminance component. For bit reduction, the separated chrominance component (C12) is subjected to symmetrical rounding (100A or 100B and 104)and limiting (104). Advantageously, symmetrical rounding of the chrominance component provides reduces a tendency for the luminance component to exhibit contouring when displayed.

Abstract: In the evaporation of process wastewater comprising a mixture of different types of wastewater, problems arise due to the formation of reaction products, so-called incrustations, which are difficult to separate. These incrustations clog up the evaporator, thus necessitating frequent stoppages for chemical and mechanical cleaning of the evaporator. The invention concerns an improved method for concentrating process wastewater by evaporation. In this method, one acid process flow and one alkaline process flow are evaporated alternately in one and the same evaporator. With this method, precipitates that are difficult to separate are dissolved in the evaporator during the respective evaporations. As a result, stoppages motivated by the need to clean the evaporator may be avoided to the utmost possible extent, while less and cheaper processing equipment is required.
