Title: Coordinated control for power plant forced and induced draft fans during startup and fan speed changes
IPC: F23N5/18
Filed: 1979-03-23
Abstract: In a power plant, a solid state sequence is provided for starting an FD or ID fan, or for changing the fan speed in response to the position of the fan inlet vanes. The sequential process is self-calibrated since process events control the stepping operation of the sequencer. At the operating fan speed, boiler air flow and pressure are controlled by fan inlet vane position in accordance with plant load demand. When the fan speed is changed, a multiplier circuit causes the fan inlet vanes to reposition so as to minimize air flow changes as the fan speed changes. When one of multiple FD fans or multiple ID fans has its speed changed at a time a fan balancer control, which normally equalizes air flow, is biased to permit different fan flows through the different speed FD or ID fans.

Title: Web monitoring apparatus.
IPC: G01N21/89
Filed: 1981-08-10
Abstract: In order to detect defects such as holes and inclusions in the manufacture of a longitudinally-moving web (10), for example paper, three cameras (22a, b and c) each containing a line array (24) of photo-diodes, are imaged transversely across respective portions of the web. Each array is repetitively scanned to sample the photo-diodes in turn. The photo-diode video signals are digitised and sequentially stored in a random address memory (52) that is addressed in synchronisation with the sampling of the photo-diodes. Arithmetic circuitry (56. 58) subtracts the fresh digital value from a given diode with the value for that diode from the previous scan and signals a defect if the difference exceeds set limits. Logic circuitry (60) controlled by the sign of the difference signals whether the defect is a hole or inclusion. The fresh value is then entered in the memory to serve as a reference for that diode on the next scan. There is also described circuitry responsive to hole signals from the camera viewing the middle portion of the web to indicate when there is no web or an irregular web, and counting and indicating circuitry for the holes and inclusions.
