Abstract: N-blocked amino acids and N-blocked peptides are obtained in the form of their esters from their aqueous solutions or slurries with the aid of a novel extraction process, wherein the N-blocked amino acid or the N-blocked peptide is converted to a water-insoluble ester by treating the solution with a diazo compound containing the ester group to be introduced, in the presence of a water-immiscible solvent, resulting in a solution of the ester in the organic solvent.   Diazo compounds particularly suitable for this process correspond to the formula (I) <IMAGE>  wherein     R<1> denotes a hydrogen atom or an organic group and   R<2> denotes an organic group, or R<1> and R<2> together with the carbon atom to which they are bonded form a cyclic organic group.

Abstract: A power supply circuit for supplying current to a MOS depletion load transistor logic circuit for use in programmers for washing machines or controllers for tumble driers. The power supply circuit comprises a depletion MOS transistor having its drain-source path connected between first and second power supply rails. The conductivity of the depletion transistor is controlled by a long tail pair amplifier which compares a reference voltage derived from a source with a voltage derived from the second supply rail using a voltage divider. The voltage divider is constructed to compensate for the effects of process variations on parameters such as threshold voltage and thereby hold the voltage divider ratio substantially constant. The voltage divider comprises two enhancement MOS transistors connected in series between the second supply rail and ground and a current source in the form of a depletion MOS transistor and an enhancement transistor connected in series between the first and second supply rails. The gates of all the transistors are connected to a junction of the current source transistor and the drain of the transistor connected thereto. The voltage across the drain-source of this latter transistor varies with threshold voltage and is added to the voltage on the second rail. Further the voltage at the gates of the enhancement transistors of the voltage divider is used to vary their conductivity.

Abstract: An electronic tone ringer responds to ringing signals on a telephone line while being unresponsive to dialing pulses or other signals on the line. Powered directly from the telephone line the ringer uses current sources to provide a high impedance to the ringer circuitry and an insensitivity to line voltage variations so that reliable operation of the ringer is maintained on long loops and with multiple ringers terminated on the line. A multitone signal for activating an electroacoustic transducer (300) is provided by frequency modulating a single oscillator (500) within the tone ringer. Frequency stability of the oscillator is insured by the use of interrelated constant current sources that provide an insensitivity to supply voltage variations over a wide range. Two of the current sources determine the duty cycle by controlling the charge and discharge current of a capacitor in the circuit. A third current source determines the voltage swing on the capacitor. By varying the current output from the third current source, the generator circuit provides a variable frequency signal.
