IPC: H04J1/06
Filed: 1963-10-07
Abstract: 1,103,108. Frequency generators; multiplex systems. GENERAL ELECTRIC CO. Ltd. 26 Nov., 1964 [7 Oct., 1963; 26 Feb., 1964], Nos. 39392/63 and 8002/64. Headings H3T and H4R. An oscillation generator (e.g. a frequency divider) comprises a number of pulse delay or memory stages in a ring with one or more stage controlled by two others whereby a pulse pattern is produced at one stage from which the desired oscillation is derived. Fig. 1 shows an arrangement for producing 4 kc/s. spaced telephone channel carrier signals from a 120 kc/s. input at 1. Input oscillations are converted to pulses at 2 and applied as shift pulses to a four stage transistorized shift register 3. The outputs from the third and fourth stages 6, 7 are applied to circuit 8 which sets the first stage to its " 1 " state upon the occurrence of the next input pulse when the outputs from the stages 6 and 7 are different. Each stage is thus switched through a pattern which is repeated after every fifteen pulses. The frequency of pattern repetition (8 kc/s.) and its harmonics are selected by filters 9 from the output of stage 7 and part of the output of stage 7 is applied to a gate 11 together with the output of a bistable circuit 10 to provide the odd harmonics for the intermediate channel carrier filters 12. The bistable circuit 10 may be supplied alternatively with pulses at twice the input pulse frequency and narrow pulse generators may be inserted in the common input lines to filters 9 and 12 to increase the harmonic output or to provide odd harmonics for selection by additional filters 9. An alternative circuit (Fig. 2, not shown) provides 48 kc/s. input signal and uses a five stage shift register. The 48 kc/s. fundamental signal is selected and mixed with a two stage pulse sequence generator to provide a wave from which the desired harmonics are selected. Alternative shift register dividers producing different pulse sequences are referred to. In a further alternative arrangement (Fig. 3, not shown) a four section delay line replaces the shift of Fig. 1, anticoincidence of pulses in two adjacent sections controlling the flow of input pulses to the line.

The novel compounds of the last general formula above wherein A1 and A2 each represents a direct bond or an alkylene radical containing up to 4 carbon atoms, R represents a phenyl or an alkyl group, R1, R2 and R3 each represents a hydrogen atom or a lower alkyl group, R4 represents a hydrogen atom an Hal represents a halogen atom, are prepared for example by treating a compound of formula R-NH-C(R1)(R2)-A2-C­N, in which A2, R, R1 and R2 have the previouslygiven meanings, with a halogen-aliphatic carboxylic acid halide of the formula Hal0-CO-A1-C(R3)(R4)-Hal, in which A1, R3, R4 and Hal have the previously-given meanings, and Hal0 stands for halogeno, preferably in the presence of a base.  By reacting a primary amine of the formula R-NA2, in which R has the previously given meaning with a carbonyl compound of the formula R1(R2)C = O, in which R1 and R2 have the previously given meanings in the presence of hydrogen cyanide or of a metal cyanide, particularly an alkali metal cyanide, a nitrile compound of the formula R-NA-C(R1)(R2)-C­N is formed which may also be prepared by reacting an amine of the formula R-NH2 or an amine, in which the nitrogen is substituted, inaddition to the group R1, by a protective group which prevents di-substitution of a primary amine and is easily removable (for example a benzal group or a carbo-benzoxy group), with a halogeno-aliphatic nitrile of the formula Hal0-C(R1)(R2)-A2-C­N or with an unsaturated aliphatic nitrile, in which the double bond is sufficiently activated by the nitrile group to react with the amine (unsaturated aliphatic nitriles of that type are represented, for example, by acrylonitrile), in the presence of a base, and, if necessary, separating the desired secondary amine compound from any simultaneously formed tertiary amine or removing any easily removable protective group (for example, by mild hydrogenolysis). This latter method yields intermediate nitriles of the formula R-NH-C(R1)(R2)-A2-C­N, in which the group A2 represents an alkylene radical containing up to 4 carbon atoms. 2-Methyl-, 2,2-dimethyl- and 2,5-dimethyl-1-phenyl-4-(N-phenylthiocarbamyl)-piperazines are prepared by reacting the methyl 1-phenyl-piperzines with phenylisocyanate.
