Title: Process controller
IPC: F02M19/01
Filed: 1980-09-22
Abstract: A three-state four-mode process controller is used for testing carburetors. In a first state the process operates at a predetermined rapid speed in a first desired direction. Desired value, feedback, and reset state signals are used to cause the process controller to change to its second state of operation when the error difference between said desired value and said feedback signal changes polarity. A correction is produced, in said second state, which causes the device to operate at a predetermined rapid speed in the opposite direction. The error difference, the rate of change of said error difference, and the reset state signal are used to cause the controller to enter the third state when the sum of said error difference and said rate of change of said error difference changes polarity. A correction signal is then produced from said desired value and said feedback signals which attempts to become saturated as soon as a new desired value is supplied or a process change occurs by utilizing the rate of change and error difference. <IMAGE>

Title: Improvements in or relating to discharge lamp circuits
Inventor: OGDEN KENNETH WHITTIER
IPC: H05B41/18
Filed: 1982-04-27
Abstract: Photoprinting discharge lamps, in particular the known Graph X-lamp, are required to allow low minimum exposure times so that they are required to reach operating power quickly. It is proposed to achieve this by holding the lamp current at a value above the preferred running current until a preset lamp voltage is reached. For this purpose the circuit may include a choke ballast (13, 14) and diode means (15, 16) to cause the current in the ballast to be unidirectional in starting and thereby to cause the ballast to saturate and have a low impedance. Switch means (17, 18) is connected to means (19, 20) responsive to the lamp voltage, to short circuit the diode means when the running voltage is approached. This allows the ballast to desaturate so that its impedance increases to the value for the preferred running current. A conventional ignitor (22) starts the lamp. <IMAGE>
