IPC: H03L7/12
Filed: 1951-10-15
Abstract: 706,940. Automatic tuning control systems. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 4, 1952 [Oct. 15, 1951], No. 24025/51. Class 38 (4) Frequency responsive apparatus for pulsemodulated oscillations, such as are employed in superheterodyne radar receivers, comprises a frequency discriminator providing differential outputs dependent on frequency deviation, which outputs are fed through separate rectifying and integrating circuits to opposite sides of a differential amplifier to produce an output AFC voltage for controlling the oscillation frequency. Pulsemodulated input oscillations from the IF amplifier V1 are applied to a Foster-Seeley discriminator C1, L1, C2, L2 with diode rectifiers D1, D2 arranged with opposite polarity so as to provide positive pulses at A across the load R1 and negative pulses at B across the load R2 the pulse amplitudes being unequal if the IF deviates from the tuning of the discriminator. The pulses are amplified and reversed in polarity in the valves V2, V3 and are fed through rectifiers D3, D4 of opposed polarity to integrating condensers C6, C7 which are shunted by resistors R6, R8 to provide time constants much greater than the pulse intervals. The integrated voltages at C and D are applied to the grids of a pair of cathode followers V4, V5, the cathodes of which are joined by equal resistors R11, R12 so as to provide zero voltage at their junction E when the IF has its correct value, and positive or negative AFC voltage according to the sign and degree of frequency deviation. This voltage is applied through an amplifier V6 to control the frequency of the local oscillator. For initial locking of the AFC system, a transitron oscillator V7 may sweep the local oscillator through a range of frequencies, and may be disabled, as soon as the discriminator operates, by a negative bias supplied from the cathode of the valve V5.

Title: Treatment of latex
IPC: C08C1/02
Filed: 1929-08-07
Abstract: 333,391. Naugatuck Chemical Co., (Assignees of Hazell, E.). Oct. 5, 1928, [Convention date]. Latex, treating.-A hypochlorite, or other compound of the general formula M-halogen-0, where M is hydrogen; an alkali or alkaline earth metal or an organic radical such as ethyl, amyl, or tertiary butyl, is added to latex. The treatment usually produces a permanent tackiness in the rubber laid down, but when applied to a strongly ammoniacal latex a glazed non-tacky condition is produced. The hypochlorite or equivalent may also cause creaming, increased stability, prevent putrefaction, act as a deodorant and produce a rapidly depositing latex. In an example, to 100 cc of latex of 38 per cent solids preserved with 0.3 per cent of formaldehyde and stabilized with 1.5 per cent of a compound known under the registered trade mark Nekal, are added, with stirring, 10-20 cc of a solution of sodium hypochlorite prepared from 200 gms of chlorinated lime, available chlorine about 24 per cent, 140 gms anhydrous sodium carbonate and 1200 cc water. After standing a few hours the latex becomes thick and if spread on fabric and air dried at about 80‹ C. a tacky layer is formed. By adding the hypochlorite. without stirring, or with moderate stirring, modified effects are produced. The action of the hypochlorite may be checked by adding sodium thiosulphate in amount sufficient to react completely with the unchanged hypochlorite. Other examples are given.

Title: Improved process for the chlorinating roasting of burnt ore
IPC: C22B1/08
Filed: 1926-10-01
Abstract: 262,392. Stephan, H. Dec. 4, 1925, [Convention date]. Chloridizing.-In the chlorinating roasting of burnt ore containing ferric oxide or the like, for the purpose of obtaining the valuable secondary metals contained therein, such as copper, zinc, silver, the known process is caused to take place in the presence of water in the nascent state. For the chloridizing, the chlorides of sodium, magnesium or calcium may be used. So that nascent water may be present during the roasting, hydroxides which split off their water of hydration at high temperatures, e.g. ferric hydroxide, may be added to the mixture. Alternatively, salts which split off water at high temperatures, such as crystallized sodium sulphate, magnesium sulphate or sodium bisulphate, may be used. Acids may be used which react with or decompose chlorides or substances contained in the burnt ore to form water or compounds from which water is formed by decomposition or reaction during the process. Hydrochloric acid may be used with restriction of air, so that hydrogen sulphide formed will react with sulphur dioxide to form water. Sulphuric acid may be substituted, which forms sodium bisulphate in the mixture from the common salt present.

Abstract: 395,889. Photographic films. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Sept. 1, 1932, No. 24417. Convention date, Sept. 22, 1931. [Class 98 (ii).] A photographic film is furnished on its rear side with a thin, anti-halation, colloidal layer coloured with non-actinic colouring matter, which layer is rendered detachable in the dry or the wet state by pretreatment of the support or by choice of the solvent by which the layer is applied. A layer produced by means of an alkaline casein solution containing formaldehyde and a colouring matter, is excluded. Suitable colloids comprise albumins, cellulose derivatives or natural or artificial resins. The treatment of the support, e.g. nitrocellulose or cellulose acetate, may consist in decreasing the gelatine content of the solution of gelatine in glacial acetic acid employed prior to the application of the colloid layer ; or the solution may contain a solvent, such as alcohol, which exerts only a feeble swelling action. Alternatively, the layer is applied to the support without pretreatment, the solvent for the layer being such as to exert at most a feeble swelling action on the support. Examples are given of (1) a suspension of soot in aqueous gelatine solution applied to an untreated nitrocellulose or cellulose acetate support, (2) a similar suspension applied to a nitrocellulose film treated with a gelatine-acetic acid-alcohol solution, (3) a celluloid-graphite mixture dissolved in an ether-alcohol mixture applied to an untreated acetylcellulose film, and (4) a cellulose ether-soot mixture dissolved in benzene and applied to an untreated acetylcellulose film.

A transformer has terminals fixed on the bobbin or bobbins, and the terminals project freely through apertures in a cover, which is fitted over the assembly, so as to be accessible from the exterior. In a bell transformer, two bobbins carrying the primary and secondary windings 14, 15, Fig. 1, are carried respectively by limbs of a core comprising a stack of U- shaped laminations, the open ends of the laminations being placed at opposite ends of the stack alternately. Each bobbin has, at each end, an integral projection on which a terminal 22 is secured. The ends of the windings are soldered to tags mechanically attached to these terminals. A tapping on the secondary winding 15 is connected to a similar terminal 33 on an insulating plate 31 mounted on the bobbin between its ends. A polypropylene insulator plate 39, which separates the primary and secondary coils 14 and 15, has end flanges 40 engaging a groove 38, Fig. 2, formed by rebates in adjacent edges of cheek plates 18. This assembly is enclosed by a plastic casing comprising a base plate 46, Fig. 7, and an interfitting cover 45 through which pass air flow passages between fins 66, extending from the cover top to projections 67 which locate the core ends. The ends of the core are clamped between projections 67 and abutments 50 on the baseplate. Detachable cover plates 55, Fig. 5, cover the terminals which project through holes 61, Fig. 7, in the casing side-wall 56, Fig. 5, and are flanked by side plates 62 and blocks 59 to which the cover 55 is secured. The casing also has a sloping lead wall 57 adjacent to each set of holes. The use of alternately placed U-shaped laminations for the core reduces the cross-sectional area of the yokes so that they become saturated under shortcircuit conditions and prevent damage to the windings.
