Title: Improvements in or relating to the manufacture of 2.4-dinitro-6-cyclohexyl-phenol
Filed: 1944-09-05
Abstract: 6-Cyclohexylphenol-4-sulphonic acid is prepared by sulphonating phenol with strong sulphuric acid to form phenol-4-sulphonic acid, and then heating this compound with cyclohexene or cyclohexanol, preferably in the presence of sulphuric acid or other condensing agent such as phosphorus pentoxide, phosphoric acid, a mixture of boric and oxalic acids, or an activated fuller's earth.  The 6-cyclohexylphenol-4-sulphonic acid so obtained may easily be converted into 2 : 4-dinitro-6-cyclohexylphenol by the action of nitric acid.  In a preferred form of carrying out the invention, phenol is sulphonated with strong sulphuric acid.  To the solution thus obtained cyclohexene is then added, and finally without isolation of the intermediate products, nitric acid is added and from the product the final 2 : 4-dinitro-6-cyclohexylphenol isolated.  The process may also be used to form 6-cyclohexylphenol by subjecting to steam distillation the condensation product of phenol-4-sulphonic acid and cyclohexene. Detailed examples are given.

Title: Regenerative-repeating system in pulse-code-modulation distribution-transmission communication systems
IPC: H04L25/24
Filed: 1963-05-02
Abstract: 986,716. Multiplex pulse code signalling. HITACHI SEISAKUSHO KABUSHIK KAISHA. May 2, 1963 [May 4, 1962], No. 17392/63. Heading H4L. A regenerative repeating system for pulsecode-modulated signals comprises a regenerative repeater adapted to receive pulse-codemodulated signals transmitted through at least one transmission line for each information channel and to distribute and transmit the signals through a different number of output transmission lines. In Fig. 2, pulses are received on three transmission lines and pass to respective regenerating circuits 2 when the pulses are regenerated with the aid of common timing pulses from a timing generation circuit 10 synchronized by the received pulses. The regenerated pulses pass to delay circuits 3, which stagger the pulses by one third of a pulse length, and to AND circuits 6. The timing pulses from generator 10 are multiplied by three in a multiplier circuit 4 and pass to a ring counter 5 which opens the gates 6 in turn; thus the combined output from gates 6 is a single pulse train which passes to a two-stage shift register 8. The output of multiplier circuit 4 also passes to a twostage ring counter which operates AND gates 6a on alternate pulses and allows the contents of register 8 to pass through pulse stretcher circuits 9 to the two output transmission lines.
