Patent GB-388465-A (GB)
Title: Improvements in and relating to metal vapour electric discharge valves
IPC: H02M1/06
Filed: 1931-10-01
Abstract: 388,465. Protective cut-out systems. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Oct. 1, 1931, No. 27378. Convention date, Feb. 2. [Class 38 (v).] To extinguish the arc in a metal vapour discharge valve used as a protection in transmission lines, a condenser is connected, through a spark gap, in parallel across the valve, and the spark gap has an ignition transformer with additional magnetization opposed to that of the primary winding. In a circuit for extinguishing a valve on a high voltage surge occurring in continuous current supply mains, the additional magnetization is such that with full normal load passing through the primary the transformer is working at the lower elbow B, Fig. 1, of the magnetization curve. Fig. 2 shows one circuit, wherein the transformer 4 ignites the spark gap 6a, 6b which thereupon connects the condenser 5 across the valve 3. The additional magnetization is supplied by a winding 46 whi h may be fed from the line, as shown, or from a separate source. The condenser 5 is charged through the resistance 16. The choke coil 11 prevents an excess current from flowing in the winding 4b and blows the arc 6 against an electrode 6c which short-circuits the ignition winding 4c so that its reactance does not reduce the peak value of the discharge current of the condenser. In a modification, Fig. 3, two spark gaps 6 and 12 are used, the ignition of the latter allowing the condenser to discharge over the former without the use of a third electrode.. The coil 11 is used to extinguish the arc in the horn spark gap 12 ; its action is assisted by an auxiliary electrode 14 connected to one horn through a condenser 15. The spark gap 6 may be caused to act first by connecting the winding 4c to the positive main. In a further modification the winding 4c acts also as the additional magnetizing winding and the winding 4b is dispensed with. The magnetizing winding 4b may be fed from a separate source which may also control a blocking grid in the valve 3.

Title: Aqueous dispersions of modified alkyd resins
IPC: C08G63/91
Filed: 1959-08-11
Abstract: Aqueous dispersions of oil-modified alkyd resins are made by neutralizing an oil-modified alkyd resin whose polycarboxylic acid component includes isophthalic acid with an aqueous solution of a substance having an alkaline reaction, e.g. ammonia, morpholine, trimethylamine or triethanolamine.  In addition to isophthalic acid, the polycarboxylic acid component may include orthophthalic, terephthalic, maleic or fumaric acid.  The polyhydric alcohol component of the resin may be derived from glycerine, pentaerythritol or ethylene glycol (or mixtures thereof) and the oil component may be derived from the fatty acids of soya, fish linseed, coconut or tall oil, with or without benzoic acid.  The water dispersibility may be improved by the addition of (a) a polar solvent such as butanol, cyclohexanol or ethylene glycol monobutyl ether or (b) a solubilizer such as sorbitan monolaurate, polyoxyethylene sorbitan monolaurate or an oil-modified maleic acid neutralized with ammonia.  The dispersions are useful in the manufacture of air-drying or stoving varnishes and paints, if desired with the addition of a pigment (e.g. titanium dioxide) or a siccative (e.g. a mixture of Pb, Mn and Co naphthenates).  They may also be used as non-drying plasticizers in aqueous phenol and urea resins.  Specifications 733,230 and 785,180 are referred to.

Title: Improvements in semiconductor switch
IPC: H01L29/744

Abstract: 1,057,823. Semi-conductor devices. - GENE. RAL ELECTRIC CO. July 15, 1963 [July 17, 1962], No. 27878/63. Heading H1K. In a gate-controlled PNPN device one transistor section has a high current gain relative to the other, the sum of the gains is just below unity and in at least one transistor section the gain increases with current. The gain of one transistor section may be made low by making the emitter width small relative to the base zone width or by arranging for the appropriate emitter-base junction to be shortcircuited. Fig. 6 shows an arrangement in which the upper base P-type region and the lower base N-type region 22 each have thin and thick portions and each emitter-base junction is shorted by electrodes 19 and portion 25 of contact 24. If electrode 24 is made positive relative to electrode 20 and an increasing positive bias is applied to gate electrode 17, the left portion of emitter 20 begins to emit electrons heavily, which then tend to travel towards portion 25; eventually the bottom emitter 23 begins to emit and the overall gain approaches unity so that switching occurs. A negative bias to electrode 17 drives electrons in P layer 21 towards the low current gain region, and also, because the lower emitter 23 is biased by currents traversing a lesser path length, the bias on 23 drops and the power transistor gain is reduced; thus turn off occurs. In a further embodiment (Fig. 7, not shown) the low emitter comprises a plurality of discrete P portions (34) which are all short circuited by contact (37). The devices may be made standard diffusion techniques, utilizing silicon with aluminium, antimony, gallium and phosphorus as impurities.

Abstract: 815,393. Amplitude-modulating apparatus. WESTERN ELECTRIC CO. Inc. Sept. 14, 1956 [Sept. 19, 1955], No. 28141/56. Class 40 (5). [Also in Group XXXIX] In an amplitude modulator using a transistor oscillator as the carrier source, the D.C. emitter/ collector voltage is obtained by rectifying the output of the microphone which is providing the modulating signal. The transistor 14 is connected as a Hartley oscillator and is energized by the microphone 11 over a full-wave rectifier 13. A capacitor 22 acts as a by-pass at carrier frequency only, hence the output of the rectifier 13 varies in amplitude with the modulating signal and the amplitude of the carrier varies accordingly. In a modification, Fig. 2 (not shown) the voltage applied to the transistor is fully smoothed and modulation is effected by a conventional balanced modulator fed by both the carrier and the modulating signal.

Title: Improvements in the production of citric acid
IPC: C12P7/48
Filed: 1948-10-29
Abstract: The production of citric acid by submerged oxidative fermentation of fermentable carbohydrate containing media with a citric acid producing strain of A. niger is improved by incorporating ammonium carbonate and morpholine in the media. Nutrient mineral substances may be present such as potassium dihydrogen phosphate and magnesium sulphate.  In examples: (I) and (II) refined sugar is fermented in a medium containing ammonium carbonate, morpholine, potassium dihydrogen phosphate, magnesium sulphate and well-water decationized by passage through a cation-exchange resin, acidified with hydrochloric acid using a 3 to 6 day old growth of A. niger from agar slants.  Warm humidified sterile air is passed through the warm medium during fermentation and citric acid is precipitated as calcium citrate; (III) and (IV) decationized raw sugar and corn syrup respectively, decationized by passage through a cation-exchange resin, are employed as starting materials in a process similar to (I), (V) refined fermentable sugar is fermented on a pilot plant scale using a column fermenter and A. niger grown on Sabourand's agar base medium for 21 days.  In tables I, II and III are shown the effects on citric acid production of varying concentrations of morpholine in media otherwise similar to that employed in example (I), whilst the fermentation of refined sugar by A. niger strains "A" and "B", the latter being obtained by ultra-violet irradiation of "A" spore suspensions are compared in similar media.  Table V compares the fermentation of refined sugar in media similar to that employed in example (I) with A. niger with varying proportions of ammonium carbonate and morpholine and with ammonium carbonate absent.  As starting materials may be employed refined sugar or low ash containing sugar materials such as raw sugar, corn syrup or high test molasses, the latter after decationization to reduce the iron content to below 1 p.p.m.  If this is present the effect may be offset by the presence of zinc ions.  Sterile, humidified air is the preferred aerating medium though other oxygen containing gases may be used. Foaming in fermenters may be controlled by the addition of anti-foaming agents such as octadecyl alcohol in mineral oil. Additional sugar may be added during the course of the fermentation, p  mycelial mats may be grown in similar media to the basal media and added to the latter after maceration or preformed submerged cells may be developed and used to eliminate or shorten the incubation period in the fermenters.  The characteristic cellular structure of the mould is described in detail.  Specification 653,808 is referred to.
