Abstract: ABSTRACT      A signal timing circuit for use in retiming circuits in  digital  signal  regenerators  in long distance telecommunications systems is disclosed.  A phase control circuit controls the timing of clock signals relative to digital signals at a re-timing gate by means of a negative feedback loop and a phase shifter.   The feedback loop maintains the desired relative timing in dependence upon a reference voltage and a voltage obtained from the phase difference of the input digital signals and the output digital signal of the re-timing gate.

Abstract: ABSTRACT OF THE DISCLOSURE         A solution polymerization process for the preparation of high molecular weight polymers of alpha-olefins selected from the group consisting of homopolymers of ethylene and copolymers of ethylene and C4 - C12 alpha-olefins is disclosed.  The process comprises feeding monomer(s), coordination catalyst and inert hydrocarbon solvent to a reactor, polymerizing the monomers at a temperature of up to 320°C and a pressure of less than 25 MPa, and deactivating the catalyst in the solution so obtained.  The catalyst is deactivated by sequentially admixing therewith a minor amount of a nitrogenous base, especially an aqueous solution of such a base, followed by a solution of a salt of an alkaline earth metal or zinc and an aliphatic monocarboxylic acid dissolved in hydrocarbon solvent.  The ratio of water : nitrogenous base should not be greater than 5.  The hydrocarbon solvent and other volatile matter are then separated from the resultant solution and a composition comprising said high molecular weight polymer is recovered.  The amount of nitrogenous base plus any water is not more than 2.5 moles per mole of halogen plus alkyl radicals in the coordination catalyst.
