Title: Improvements in or relating to electric power transformers
IPC: H01F29/02
Filed: 1934-06-02
Abstract: 433,904. Transformers; automatic regulation; electromagnetic switches. ELECTRICAL IMPROVEMENTS, Ltd., Carliol House, Newcastle-on-Tyne, and PATTINSON, R. R., 18, Otterburn Avenue, Gosforth, both in Northumberland. June 2, 1934, No. 16477. [Classes 38 (ii) and 38 (iv)] [See also Group XXXVII] Small distribution transformers are provided with a manually operated off-load tap changing switch to meet seasonal changes in load conditions and with automatically controlled on-load tap changing gear of relatively few steps to meet daily fluctuations over a narrower range. The latter may be made responsive to terminal voltage or to load current or both. In the arrangement shown the off-load switch C operates on a part A of the primary in series with a part A1 having two steps of regulation controlled by pairs of mercury switches E, E<1>, F, F<1> each of which in its intermediate position of operation is arranged to connect a pair of resistances E2, E3 or F2, F3 across adjacent taps and in its extreme position to short circuit a resistance to provide a direct connection to the corresponding tap. The switches E, E operate to transfer from A2 to A3 under the control of a voltage responsive relay G connected across a condenser G2 connected in series with a choke G1 and current-limiting resistance G3 across the terminals of the secondary B. At normal voltage values the core of the choke is saturated and a part of its winding is short-circuited by a mercury switch G4 arranged to be operated simultaneously with the switches E, E1. With the core saturated the inductance of the choke is such as to render the circuit resonant at the supply frequency, and sufficient current flows to cause the relay to hold its armature. With decrease in voltage the saturation is altered and the resulting departure from resonance causes a large drop in current which ensures release of the relay armature and operation of the switches E, E1, and G4. The latter is arranged to introduce additional turns into the choke winding thus ensuring that the choke does not become saturated and its circuit resonant until the voltage reaches a higher value than normal thus preventing hunting. The second tap changing step is effected by operation of the switches F, F1 under control of a current responsive relay H, and in order to ensure that this does not operate before the relay G its terminals may be short-circuited by a mercury switch H1, the short circuit being removed by operation of the switch H1 simultaneously with the switches E, E1, and G4.

Patent GB-791602-A (GB)
Title: Fluid-impervious graphitic articles and method of making the same
IPC: C04B41/50
Filed: 1955-06-08
Abstract: An article of porous graphite is rendered impervious to liquids and gases by impregnating with a CO disproportionating catalyst and passing CO through the pores of the graphite at a temperature suitable for its disproportionation, thereby depositing carbon in the pores.  Catalysts specified are the oxides of iron, nickel, cobalt, chromium, molybdenum and vanadium. A saturated aqueous solution of a heat decomposable salt may be employed, and impregnation effected under reduced or atmospheric pressure, the article dried by heating to 100 DEG  C. and the salt decomposed to oxide by heating to approximately 600 DEG  C.  In the case of large pieces of graphite, the heating may be conducted in an inert atmosphere. Disproportionation may be effected with iron oxide at a temperature of 400-650 DEG  C., preferably 575 DEG  C., cobalt oxide at a temperature of 550-700 DEG  C., preferably 650 DEG  C., and nickel oxide at a temperature of 400-575 DEG  C., preferably 475 DEG  C. With an article having a porosity of 0.085 D'Arcy, about 10 per cent of carbon is required to render the article impervious.  In the example a porous graphite disc was impregnated with Fe(NO3)3, after drying at 100 DEG  C. the disc was heated for 2-3 minutes at 600 DEG C. CO was then passe through for 200 hours at 575 DEG  C.  The permeability thereby dropped from 0.085 to 0.0003 D'Arcy.

[Classes 2 (iii) and 15 (ii)] [Also in Croup III] p-Aminobenzyl acylamines of the general formula where R represents an aliphatic or alicyclic group containing more than 5 C-atoms, and R<1>, R<11> represent alkyl, cycloalkyl, or aralkyl radicles Which may be the same or different, and one of R<1> and R<11> may be hydrogen, are prepared by reacting non-aromatic carboxylic acid amides of the formula R.CO.NH2 with p-amino-benzyl aminoaryl compounds. As acid amides, the amides of stearic and oleic acids, palm kernel fatty acid, napthenic acid, resin acid, hydrogenated fish oil fatty acid and seed oil fatty acid, arc specified. The products are converted into quaternary ammonium compounds, which can be used as wetting, dispersing or emulsifying agents, by treatment with unsubstituted alkylating agents, or with alkylating agents substituted by halogen and /or hydroxyl groups, e.g. dimethyl sulphate, diethyl sulphate, butyl bromide, allyl bromide, glycolchlorhydrin glycerine-alpha-chlorhydrin, and ptoluene sulpho - isobutylcarbinol ester. The aminobenzyl aminoaryl compounds used as starting materials are obtained by treating primary amines, e.g. p-toluidine, sulphanilic acid, metanilic acid and naphthylamine sulphonic acids, with formaldehyde, or a substance producing formaldehyde, and with secondary or tertiary aromatic amines having a free p-position, such as dimethylanifine, diethylaniline, ethyl- or methyl-benzylaniline, ethyl-otoluidine, and cyclohexylaniline. In an example, stearic acid amide is condensed with p-dimethylaminobenzyl sulphanilic acid in ammoniacal solution, and the product is converted into a quaternary ammonium compound by heating with diethyl sulphate. The final product is suitable for use as a softening agent, for cotton and precipitated cellulose.
