Abstract: Solns. of ε-caprolactam(I) in benzene, toluene, or xylene were purified by washing with 15:1-1:3 I-H2O solns. until an aquil. between both solns. occurs.  Thus, I-H2O mixt. produced by a Beckman rearrangement of cyclohexanone oxime in oleum was neutralized with NH3 and extd. with C6H6.  The soln. of I in C6H6(contg.I 25.2, C6H6 72.6, and water 2.2 %) was pumped at 2000 ml/h to a 20-tray extn. column and 60 ml/h water was pumped to the top of the column.  The purified I soln. obtained at the top of the column was distd. to give I having  color no. 5, permanganate no. 40,000, UV no. 95, m.p. 69.10, and volatile base content 0.3 mg equiv./kg.

Filed: 1987-02-24
Granted: 1990-06-29
Abstract: The automatic power control circuit for a signal power amplifier maintains the output power to one of a number of output power levels. The output power level is controlled by an externally- generally level control signal which is used by a square wave signal generating circuitry for controlling the duty cycle of the generated squeare wave. The square wave is integrated by a filter network to produce a reference voltage level. The output voltage level of the RF amplifier is compared with the reference voltage level. The difference between the two signals is used to control a drive circuit for generating the proper control voltage for controlling the RF amplifier so that the desired output power level is maintained.
