Trifluoroamine oxide is produced by reacting nitrosyl fluoride and elemental fluorine. Preferably the reaction takes place at normal pressure under the influence of ultra-violet radiation of wavelength 2000-4000Š, the temperature being maintained at 25-50‹ C. for 2 to 6 hours; the pressure in the reaction tube is then reduced and trifluoroamine oxide separated from excess nitrosyl fluoride by fractional condensation at low temperature. The nitrosyl fluoride-fluorine reaction mixture may be made by reacting nitric oxide and fluorine at room temperature. In examples, reaction takes place in a nickel cylinder with ultra-violet transparent barium fluoride windows at each end. Trifluoroamine oxide is claimed and its uses referred to in Specification 1,038,840.

Abstract: 673,298. Dry rectifiers. BRITISH THOMSON-HOUSTON CO., Ltd. July 10, 1950 [July 22, 1949], No. 17212/50. Class 37. A dry rectifier comprises a sintered mixture 2 of sulphides including a sulphide of a metal of Group II of the Periodic Table, a molybdenum electrode 1 on which a barrier layer of sulphide is electro-formed and a terminal 4 of a metal which reacts with sulphur to only a limited extent, e.g. platinum, chromium, nickel, aluminium, tungsten, with or without a thorium coating and nickel-chromium alloys. In the manufacture, a mixture of from 5 to 50 per cent molybdenum disulphide, 2 to 10 per cent free sulphur and the remainder one or more Group II sulphides, e.g. calcium or cadmium or a mixture of calcium and mercury sulphides, is pressed about the terminal elements and sintered at between 500‹ and 800‹ C. Subsequently, to form the molybdenum disulphide layer at the cathode, a direct current is passed through the device with the molybdenum lead as cathode, the current density being from 5 to 200 amperes per square inch and the temperature from 260‹ to 360‹ C. The current is preferably reversed for a short time to build up a sulphide bond between the other terminal and the sintered mass. Instead of a wire electrode 1, a plate or cap may be used.

IPC: H04L27/233
Filed: 1969-04-02
Abstract: 1281169 Digital transmission systems MARCONI CO Ltd 19 Nov 1969 [2 April 1969] 17293/69 Heading H4P In a differential 4-phase phase shift transmission system the data may be sent either in a first form in which the possible shifts are 0, 90, 180 and 270 degrees or in a second form in which the shifts are 45, 135, 225 and 315 degrees. The modulator and demodulator are designed to deal with signals of the first form, an additional shift of 45 degrees being impressed on the transmitted carrier and on the receiver reference carrier when switched to deal with signals of the second form. Transmitter, Fig. 1.-Binary data at 10 is converted to dibit form on leads X, Y by coder 3. The signals on X, Y control the phase of a carrier signal, derived from clock pulse generator 1, by deleting pulses fed to the dividers 5, 6. The resulting signal is in the first form and is transmitted via 12-14. If switch 11 is closed dibit-rate pulses are added to the output of generator 1 so causing an additional 45 degree shift in the output of divider 6, resulting in transmission in the second form. Receiver, Fig. 2.-The signals received at 17 pass to a differential phase detector 22 which outputs dibits to decoder 31 to provide the binary signals at 32. Pulse generator 24 feeds divider 27 whose output is of carrier frequency and is synchronized with the received carrier by unit 23 so that its phase is the same as that of the dibit prior to that currently being received. This reference carrier passes to detector 22 as two carriers 90 degrees apart. Generator 24 also feeds divider 25 whose dibit frequency output is synchronized on the received dibits by unit 29. If switch 30 is closed the output of divider 27 is shifted by 45 degrees so that signals of the second form will be correctly demodulated.
