Abstract: 510,487. Forming protective coatings on metals. HIGH DUTY ALLOYS, Ltd., and ALLEN, F. A. Sept. 13, 1938, No. 26684. Addition to 482,689. [Class 82 (ii)] In a modification of the process for coating articles of magnesium rich alloys forming the subject of the parent Specification, an acidifying agent is added to the aqueous solution of alkali dichromate and nickel sulphate, chromium sulphate, or nickel ammonium sulphate, to produce or maintain a pH value between 2 and 6.4, and preferably between 3.4 and 4.4, the process being thereby facilitated and the protective coating improved. Preferably the acidifying agents employed ionize in solution only slightly, examples being organic acids and salts thereof. An example is given of a bath containing chromium sulphate, potassium dichromate, acetic acid, and sodium acetate. The articles may be cleaned in a bath of chromic and nitric acids, and may be then given a sulphuric acid dip, before being treated in the coating bath.

Title: Process for the manufacture of dioxy-nitro-arylaminoanthraquinones and the products obtained thereby
IPC: H01P9/00
Filed: 1955-09-19
Abstract: Mixtures comprising 1,5- and 1,8-dihydroxy-a -nitro-a -arylamino-anthraquinonones are obtained by reacting a mixture, consisting substantially of dinitroanthraquinones and containing at least 40 per cent of 1.5-dihydroxy-4,8-dinitroanthraquinone and 1,8-dihydroxy-4,5-dinitroanthraquinone, taken together, with an aromatic amine of the benzene series free from water-solubilizing groups at 100-150 DEG  C. in absence of more than 5 per cent water calculated on the reaction mixture, and substantially in the absence of an organic solvent.  The mixture used as starting material may be obtained by dinitrating anthraquinone, exchanging the nitro groups for alkoxy or phenoxy, again dinitrating, and then hydrolysing the alkoxy or phenoxy groups; after each nitration by-products which are obtained in addition to the isomers containing nitro groups in different rings may be removed by fractional precipitation by adding water to the sulphuric acid solution of the mixture.  The amines employed may contain halogen or alkyl, alkoxy, or oxyalkyl substituents up to 4 carbon atoms. The products may be used as pigments, or for dyeing or printing cellulose esters, nylon, polyurethanes, polyvinyl compounds, and polyesters.  In examples, mixtures as described above are heated with: (1) aniline; (2) m-aminobenzyl alcohol; (3) p-aminophenylethyl alcohol; (4) a crude mixture of xylidines; (5) m-toluidine; (6) p-anisidine.  A further example describes the acid-pasting of a product derived from aniline and its use to dye cellulose acetate blue shades.

IPC: H04M11/02
Filed: 1937-10-05
Abstract: 503,498. Exchange and direct-call  systems. SHIPTON, E. Oct. 6, 1937, No. 26988. [Class 40 (iv)] Operation of a key at a.telephone substation causes incoming calls to operate a relay which controls visible or audible signals or both at various parts of the building and extends the telephone line to a circuit over which a reply signal is given either automatically (e.g. by a gramophone or buzzer). or by an attendant. In an arrangement for a direct-call intercommunication system, Fig. 1 (not shown), the key removes a short-circuit from the relay which is thus enabled to pull up in response to the calling signal. In the exchange sub-station shown, the key energizes a relay R which connects the upper winding of relay T to the telephone line. On the arrival, of a call, T locks over its lower winding, connects the line to circuit 22, 23 and lights characteristic lamps 25a, 25b at the substation and elsewhere. The relay is unlocked at 20 by an attendant, or by the release of R by the subscriber, or otherwise from the indicating lamps. In a modification the relay may complete a conference circuit and transmit a code signal over a separate ringing circuit.

Patent GB-1017151-A (GB)
Title: Improvements in or relating to the electrolysis of solutions
IPC: C25B15/04
Filed: 1962-07-17
Abstract: In an electrolytic cell, e.g. a cell for electrolysing alkali metal chloride solutions using one or more graphite anodes and a mercury cathode, the optimum electrode gap with regard to cell voltage is obtained by applying a constant voltage between the electrodes and advancing the anode towards the cathode until the increase in current intensity ceases to be a straight-line function of the amount by which the electrode gap is reduced and rises sharply.  This occurs before short circuiting.  The anode may be withdrawn subsequently by a specific distance empirically determined so as to obtain the optimum electrode gap with regard to the faradic output of the cell. The anode may be advanced by an apparatus as claimed in Specification 851,415.
