Abstract: Abstract A multiplex bus system (Fig. 1) comprises a master control unit (MCU) (12) connected to at least one receiver-transmit unit (RTU) (16, Fig. 3) by a data bus (14).  The MCU transmits to the RTU a message (Fig. 5) comprising a synchronization pulse (SYNC') of known duration (2 2/3 T).  The message also includes successive, time-spaced level transitions, which are separated from each other by time duration T.  The transitions mark respective  boundaries of data bits within each message.          The RTU includes a clock pulse source (81, R, C), which utilizes the synchronization pulse of each message to determine the number, P, of second clock pulse source pulses per duration T.  The number, P, is used in conjunction with the level transition signals in the message to mark in the RTU the positions of additional transitions, which additional transitions are positioned within data bit positions of the message to indicate values of respective data bits.

Abstract: ABSTRACT OF THE DISCLOSURE       This invention provides a method for conversion of congruently melting polycrystalline fibers to single crystal fibers.  The method is particularly useful for production of fibers ranging from about 30 µm to about 1,000 pm in diameter, which are capable of infrared (IR) transmission and of functioning in nonlinear optical applications. The polycrystalline fiber is converted to a single crystal fiber by creating a melt zone near one end of said polycrystalline fiber and then causing said melt zone to travel a length of said polycrystalline fiber fit least once, so that the fiber continuously melts and recrystallizes into a single crystal along the length to that such length becomes one continuous crystal.     In another embodiment of the invention, the method described above is utilized to improve the surface characteristics of a single crystal.     In yet another embodiment of the invention, the method disclosed above is utilized to produce a fiber comprised of a polycrystalline core surrounded by a single crystal sleeve or large grained crystal sleeve which evidences single crystal behavior.  This method is particularly useful for production of fibers ranging from about 30 µm to 1,000 µm in diamter, which are capable of infrared (IR) transmission.  If the sleeve is a sufficiently large proportion of the fiber produced, this method is particularly useful for production of fibers which may be capable of functioning in nonlinear optical applications.

Abstract: Abstract Pattern-recognizing self-tuning controller A pattern-recognizing, self-tuning controller is provided for controlling a process wherein measured characteristics  including  at  least  one  peak of an error signal, derived from the differences occurring over time between the values of a process controlled variable  and  a  desired  set-point  level  for  that variable,  are  used  for  identifying  the  behavior pattern of the  error  signal  so  that  an  operating parameter of the controller can be changed as re-quired to minimize process recovery time whenever the process is subsequently disturbed or an abrupt change is made to the set-point level at some later time.          The preferred embodiment of the device is in the form of a proportional-integral-derivative (PID) control-ler in which the PID coefficients are calculated in accordance  with  prescribed  relationships  that  are based on damping, overshoot and time period charac-teristics of the error signal.  Provisions are also made for including a user-specified noise threshold in order to reduce substantially the possibility of detecting a noise peak as a true peak of the error signal.  A pre-adapt mode is also included, in which the controller automatically determines the initial values of the PID coefficients, the noise threshold, and the approximate time scale of the process, before on-line adaptive control of the process is given to the controller.

The composi-tion used in the method incorporates an aqueous solution which comprises in-situ nitrogen-generating components together with a sufficient amount of a buffered pH adjuster to produce a buffered pH value for the aqueous solution to abate the time of the reaction rate of the nitrogen-generating components to a level permitting introduction of the components into the iso-lated length prior to completion of any significant portion of the reaction required to effect temperature melting of the paraffin deposits.  In a preferred form, a crystalline modifier may be incorporated into the hydrocarbon solution.
