Abstract: A method and apparatus is provided for controlling the effect of centrifugal force on pulp stock while being ground in the grinding space of a defibrating apparatus defined between a pair of grinding discs which rotate relative to one another in a fluid environment under superatmospheric pressure and corresponding elevated temperature. The grinding space includes a central portion, a first outwardly extending grinding space and a second outer grinding zone extending at an inclined angle from the first grinding zone. Pulp stock to be ground is introduced into the central portion and accelerated through the first and second grinding zones by centrifugal force generated by the rotating discs. The inclined grinding zone serves to split the centrifugal force into a vector perpendicular to the direction of flow of the pulp material and a vector aligned with the axial flow to reduce the accelerating force on the pulp grist in the direction of outward flow. By reducing the outward acceleration, the dwell time of the grist in the second grinding space is increased, resulting in optimum utilization of the entire grinding space for optimum refining efficiency.

Abstract: Method and apparatus for the operation of a direct current (d.c.) motor requiring no start-up resistor and accompanying switches. Regenerative braking is obtained and the torque interference in the operation is carried over to the electrical input after being dampened, due to the "soft" speed/torque characteristic. The d.c. motor is directly controlled by a technique which stimulates either the characteristics of a shunt-wound motor or a series-wound motor. A command signal is provided by an adjustable signal source which is adjusted in accordance with the armature current desired. A d.c. voltage source is controlled to provide an armature current in accordance with the command signal. When the armature voltage reaches its nominal value, a controlled d.c. current source is regulated in accordance with an error signal which is the difference between the command signal and the armature current, to regulate the excitation. The armature current/armature voltage control is thereby switched to an armature current/excitation control under which control the d.c. motor follows the "soft" speed/torque characteristic curve. To achieve braking, the command signal is reversed. This condition is detected by the differential unit to initiate braking. By maintaining the given nominal load current in accordance with the command signal setting of the signal source, motor speed decreases until the excitation reaches its nominal value. This condition is detected, causing the armature current/excitation control to be switched back to the armature current/armature voltage control. With decreasing speed, armature voltage is reduced in value until the d.c. motor stops.

Abstract: A time division switching system having distributed control processors is disclosed. The switching system includes time-slot interchange units having associated subscriber sets and a time-shared space division network for interconnecting the time-slot interchange units. Each of the time-slot interchange units and the time-shared space division network are controlled by separate control processors. In response to called subscriber set identifying information from a calling subscriber set, the control processor associated with the time-shared space division network completes the communication path through the time-shared space division network to connect the time-slot interchange units associated with the calling and called subscriber sets. The control processors in the time-slot interchange units then determine if communication path continuity is present between them before the subscriber sets are connected to the communication path through the time-slot interchange units. Additionally, arrangements are included for detecting loss of continuity in the communication path.

Abstract: A thermal imager comprises a scanner (13), detector (14) with mount (14A) cooled substantially below ambient temperature, and which via a reflector (16) on the locus (15) along which an image of the detector (14) is effectively scanned provides a characteristic radiation feature to the detector (14) in superimposition with the scanned radiation from the scanner (13). The scanner (13) operates with less than 50% efficiency so that in the detector output signal the scene-derived waveform has a duration T1<50%T, where T is the period of the detector output signal. The characteristic radiation feature gives rise to a sync signal at the detector output and is located prior to and closely adjacent the scene-derived waveform at a time interval T2 prior to the end thereof. This sync signal is detected by a recognition circuit (20) and activates a monostable forming part of a clock circuit (22) for a duration T3 such that T2<T3<50%T. The clock circuit (22) controls the timing of signal processing circuitry (24) and a video output device (25) connected to the output of the detector (14).
