Title: Manufacture of highly chlorinated hydro-aromatic products containing nitrogen
IPC: C07C23/10
Filed: 1923-02-20
Abstract: Highly chlorinated hydroaromatic products containing nitrogen are prepared by chlorinating hydrochlorides of aromatic amines with gaseous chlorine in an indifferent liquid, moisture being excluded. Thus aniline hydrochloride, chlorinated first in cold and then in hot chlorobenzene, yields an octochlor-chlorketimido-hexahydrobenzene, and in benzene, if chlorination is stopped when dissolution has occurred, chiefly a hexachlor-chlorketimidohexahydrobenzene: a - and b -naphthylamines yield pentachlor-chlorketimido-tetrahydronaphthalenes; with b -naphthylamine the reaction is complete in cold benzene suspension but with a -naphthylamine a hot chlorbenzene suspension is necessary: a - and b -aminoanthraquinones similarly yield pentachlor-a - or b -chlorketimidotetrahydroanthraquinone when chlorinated in benzene and chlorbenzene respectively.  Examples are given of the preparation of the above specified ketimides, the suspensions of the amine hydrochlorides being first prepared by passing gaseous hydrochloric acid into benzene or chlorbenzene solutions of the parent amines.

Title: Improvements in radio communication systems
IPC: H04B1/38
Filed: 1944-03-17
Abstract: 575,462. Wireless receiving systems. STANDARD TELEPHONES & CABLES, Ltd., and SEATH, E. G. March 17, 1944, No. 5049. [Class 40 (v)] A combination of a wireless transmitter for telegraphy and a receiver for signals of different type, such as speech, characterised in that one aerial is used for both and switching means provided whereby the act of keying the transmitter automatically transfers the aerial from the receiver to the transmitter and vice versa. It is provided that the radio-frequency voltage on the aerial shall be zero before it is connected to the receiver, and conversely, that on changing over to transmit no radio-frequency energy shall appear at the aerial terminal of the transmitter until the aerial is connected to it. In the Figure, when the key 5 is open, the aerial 1 is connected to the receiver 2 by way of contacts 8, 10 of relay 7, which is unenergized ; at the same time, the grids of the R.F. oscillator V1 and amplifier V2 of the transmitter 3 are over-biassed from the battery 4. On closing the key 5, the grid of valve V1 is grounded and oscillation commences ; also the grid of valve V2 is biassed suitably for amplification, since current flows in the circuit comprising the key 5, battery 4, resistances R1, R2 and relay 6, which causes a voltage drop to occur in the resistance R1. Current in the relay 6 causes contacts 11 to close and the aerial relay 7 to be energized, whereby connection 8, 9 is made and the aerial transferred to the transmitter. Relay 7 may be of the kind described in Specification 562,342, [Group XXXVII]. On opening the key 5, bias is applied to valves V1, V2 before the relays 6, 7 transfer the aerial to the receiver. It is arranged that the output circuit of the transmitter 3 shall be out of resonance until the aerial 1 is connected to it, and an additional contact 12 on relay 6 may be used to shut down the receiver when transmitting.

Abstract: 675,470. Discharge apparatus. RADIO PATENTS CORPORATION. Feb. 26, 1948 [April 14, 1942], No. 5885/48. Class 39 (i). In a method of ageing a discharge tube having a space-charge grid, control grid, screen grid, cathode and anode, the space charge grid, screen grid and anode are connected together and an alternating voltage is applied between them and the cathode, which simultaneously is independently heated. It is stated that this method removes alkaline earth from the control grid. In one form, a tube which according to Specification 675,469, is provided with cathode 14, Fig. 2, space-charge grid 1, control grid 2, a further grid 3, a screen grid 4 and suppressor grid 6, is first heater flashed, and then connected as shown before the application of the alternating voltage, which is considered to be too great if the series-connected lamp shown glows brighter, or a series-connected D.C. meter gives a lower reading. The current from the grid 1 to the cathode 14 and grid 2 on one half-cycle should be less than that in the reverse direction on the other half-cycle. Cleaning-up of residual gas during the process can be completed if necessary by subsequent means. In a further form, the tube is provided with a driver section comprising cathode 14, Fig. 3, grid 15 and anode 16. Ageing comprises operating the tube for 2 minutes with a specified heater voltage with both switches S, S1 open. Switch S1 is then closed for 5 minutes, the heater voltage being reduced. The alternating voltage is then applied, switch S only being closed, and after 4 minutes the alternating voltage is reduced for a further 10 minutes. In a modification, the grid 3 also may be connected to the grid 1. The emission tests for the driver and output sections should be made separately and circuits for this purpose are shown.
