Abstract: ABSTRACT            A clock setting circuit is provided at a receiving modem for adjusting the phase of an timing signal defining the signal sampling instants.  The received signal is filtered in two filters to derive a first signal having a phase ?1 and a frequency f1 equal to fc - 1/2T, fc being the carrier frequency and 1/T being the transmission baud rate, and a second signal having a phase ?2 and a frequency f2 equal to fc + 1/2T.  The first and second derived signals are combined to derive an error signal indicative of the phase difference ?2 - ?1 which difference is used for adjusting the phase of a phase locked oscillator which provides the timing signal.

Abstract: Abstract:  Roofs like other portions of buildings expand and contract with temperature changes in various climates and seasons.  Regardless of outside temperature conditions there is almost no contraction and expansion in the roof described. Means and methods are devised for excluding all moisture from roof joints, thus the freezing and thawing conditions which usually exist are here absent.  Unlike other roofs there is no overall expansion and contraction to open cracks to receive dampness, or to require roof repair or replacement.  This is a permanent non expanding and non contracting roof structure.

Abstract: Title of the Invention:   MECHANICAL STORED ENERGY          POSITIONING ACTUATOR                  ABSTRACT OF THE INVENTION     A motor driven actuator, providing continuous positioning of an output shaft, and employing energy storage which allows the shaft to return to a predetermined position on failure of the input power source or other predetermined occurrence.  Drive motor torque requirements are minimized through sequential application of input torque to the energy storage and actuator load.  This arrangement insures that adequate energy storage for return of the output shaft is continuously available during normal actuator operation including alternate output shaft positioning.   When utilized to operate a fluid control valve, the valve actuator combination provides a fail-safe valve which under emer-gency or other prescribed conditions provides return of the valve to a shaft condition from any normal operating position throughout the limit of the valve travel.   The above functions are provided through the use of a simple highly reliable structure utilizing a reduced number of relatively simple components and a drive motor which can be sized for the output torque alone without additional torque requirements due to the presence of a stored energy device.

The process comprises reacting in A first stage cyanuric chloride and a selected primary alkylamine at elevated temperature to give a dichloro-monoalyl-amino-s-triazine and reacting in a second stage this dichloro-monoalkylamino-s-triazine with an excess of a primary alkylamine which may be introduced as a pure liquid, as gas or as a solution in water.  The process gives consistent yields in excess of 97% of monochloro-diamino-s-triazines.  Because of the anhydrous conditions in the new caustic-free process and the feasibility of recycling the excess of monoalkylamines employed, no serious effluent problems arise.
