Publication number: 20090299087Abstract: The process for manufacturing unsaturated mononitriles, such as acrylonitrile and methacrylonitrile, has been modified to add a partially condensed quench effluent stripper column to remove high boiling organic compounds from the reactor effluent prior to introduction into the extractive distillation recovery column. The high boiling organic compounds are preferably removed after the ammonia in the reactor effluent has been neutralized and the neutralization products have been removed. The targeted high boiling organic compounds are associated with fouling in the recovery section of the plant.Type: ApplicationFiled: May 28, 2008Publication date: December 3, 2009Applicant: Solutia, Inc.Inventors: Valerie S.

Patent number: 4741501Abstract: Collective stick inputs are provided (18) to a high pass filter (24) when collective stick reversals in excess of a threshold collective authority rate (15%/sec) and in excess of a threshold frequency (3 stick reversals per second) are sensed. The output of the high pass filter (24) is scaled (26) and subtracted (14) from the collective inputs so as to effectively cancel the threshold stick reversals. Otherwise, if no stick reversals in excess of the threshold collective authority rate are sensed for a threshold time interval (5 seconds), the collective stick inputs are not provided to the high pass filter.Type: GrantFiled: June 26, 1987Date of Patent: May 3, 1988Assignee: United Technologies CorporationInventors: Douglas H.

Patent number: 4580223Abstract: An aircraft automatic flight control system (AFCS) includes a pair of fast, limited authority inner loop actuators responsive to signals indicative of aircraft attitude or other flight parameters such as airspeed, the inner loop being recentered by an outer loop actuator responsive to attitude or other aircraft parameter-indicating signals (54,55). Commands applied to the outer loop are applied in a lagged fashion in opposite direction so as to drive the inner loop actuators back toward the center of their authority. The rate of response of the outer loop is adaptive in response to magnitude of inner loop input (101, FIG. 2). A pitch bias command is provided to the inner loop as a function of airspeed multiplied inversely with collective pitch, and as a function of the rate of change of collective stick position, so as to provide a positive static pitch trim gradient and decouple collective pitch from the longitudinal cyclic pitch channel.Type: GrantFiled: November 7, 1983Date of Patent: April 1, 1986Assignee: United Technologies CorporationInventors: Stuart C. Wright, Richard D. Murphy, Don L. Adams

Patent number: 4570480Abstract: Method and apparatus are provided for determining the formation pressure. The magnitude of formation pressure may be derived as a function of changes in bottomhole pressure following swabbing the borehole to draw formation fluids into the borehole, monitoring the borehole for influx of formation fluids, determining the reduced pressure due to swabbing, repeating the swabbing and monitoring steps until an influx of formation fluids is detected thereby determining the pressure of the formation.Type: GrantFiled: March 30, 1984Date of Patent: February 18, 1986Assignee: NL Industries, Inc.Inventors: John E. Fontenot, Richard D. Murphy

Patent number: 4566101Abstract: An oscillatory-failure monitor (101) compares a parameter of a plurality of signals (A, B) within a tolerance (TOL) to determine agreement or disparity among the signals. Each discrete miscompare occurrence (i.e., singular disparity following full agreement) is counted by incrementing (27; 54) a counter (OSCCT; CNTR). The counter is decremented (32; 62) whenever the signals compare for a predetermined time interval (29; 47). An oscillatory-failure is declared when the counter increments to a threshold (28, 21; 57, 58, 60). Both digital (FIG. 1) and dedicated hardware (FIG. 4) embodiments are disclosed.Type: GrantFiled: February 28, 1983Date of Patent: January 21, 1986Assignee: United Technologies CorporationInventors: Joseph P.

Patent number: 4564908Abstract: A torque limiting altitude hold system for a helicopter engages torque limiting (56, 203) when excessive torque is anticipated (138, 202) as determined by the summation of present torque and torque rate times a reference value (126, 194) exceeds maximum torque with torque limiting engaged, altitude commands are faded out (42, 189) and torque commands are faded in (44, 190) and the collective command integrator is switched from altitude to torque (48, 54; 181, 185), torque limiting is ended in response to negative altitude commands or anticipated desired altitude signal (96, 150, 152; 205, 206); the anticipated desired altitude is determined by subtracting from the altitude error a time function of the altitude rate (84, 90; 193), torque limiting is not allowed to reengage for two seconds after disengaging (144, 204) nor within three seconds after reaching desired altitude during an automatic descent (146, 207), the system provides smooth transitions from altitude control to torque control, without oscillationType: GrantFiled: February 28, 1983Date of Patent: January 14, 1986Assignee: United Technologies CorporationInventors: Douglas H. Clelford, Joseph P. Skonieczny, Richard D. Murphy

Patent number: 4563743Abstract: A maneuver force gradient system causes a helicopter, that otherwise tends to pitch up in a banked turn, to pitch nose-down. A command signal (25) is provided as a function of the roll angle to operate the longitudinal trim actuator (27) which automatically moves the cyclic control (50) resiliently (28) forward to push the nose down. The pilot must consequently pull back on the cyclic control (50) to achieve a desired pitch attitude, thereby establishing a longitudinal positive maneuver-force gradient. The system is operable only when the pilot initiates a roll (33, 38, 50, 51) and the roll angle equals or exceeds 30.degree. (30, 33, 36, 37). Both analog (FIG. 1) and digital (FIG. 2) embodiments are disclosed, and the invention may be practiced in association with an AFCS (101) having the longitudinal trim actuator (27) and resilient linkage (28).Type: GrantFiled: February 22, 1983Date of Patent: January 7, 1986Assignee: United Technologies CorporationInventors: Richard D. Murphy, Douglas H. Clelford

Patent number: 4519626Abstract: An adjustable mounting assembly has a slot through the control arm of a steerable wheel suspension system in which a threaded stud of a ball joint extends. Nuts threadably engage the stud and clamp the control arm in place to fix the spindle in an adjusted position. The nuts are longitudinally adjusted along the stud to preload the ball joint to a desired amount.Type: GrantFiled: April 26, 1983Date of Patent: May 28, 1985Assignee: Ford Motor CompanyInventors: Richard D. Murphy, Marvin N. Sokulsky

Patent number: 4500967Abstract: An automatic flight control system, for an aircraft having a roll attitude retention outer loop actuator (29), a roll stability inner loop actuator (25) and a control stick (26) for positioning control surfaces of the aircraft to control its roll attitude, includes means (54, 55) to provide a roll error signal (56) indicative of the deviation in roll attitude from a desired roll attitude. The roll attitude retention outer loop actuator (29) is controlled by a proportional (61) and integral (62) function of the roll error when force is not applied to the stick, but only as a proportional function when force is applied to the stick (48, 49, 51, 62). The roll stability inner loop actuator is controlled by a washed out (72) proportional (64) function of the roll error signal to provide short-term roll retention at roll attitudes established by the control stick during turns against trim. Sensing force on the stick (51, 95, FIG.Type: GrantFiled: November 27, 1981Date of Patent: February 19, 1985Assignee: United Technologies CorporationInventors: Richard D. Murphy, Ricardo L.
