A sintered electrical resistor with a negative temperature coefficient comprises nickel oxide having a lithium oxide content of from 0.1 to 10 mol. per cent and a copper oxide content (calculated as CuO) of from 1 to 30 mol. per cent. The oxides of nickel, lithium and copper (or substances which change to the oxides when heated) are mixed together and moulded whilst adding a binding agent. The mixture is then sintered in an oxidizing atmosphere, preferably air, at a temperature preferably between 1, 100‹ and 1, 300‹ C. A method of making a more conventional resistor is described whereby nickel oxide with lithium carbonate added in such an amount that the mixture contains 1.5 mol. per cent of Li 2 O is ground in a ball mill with alcohol (previously saturated with lithium carbonate) for 16 hours. The product is filtered and dried and then a binding agent consisting of a solution of 2 gms. of methyl acrylate with 1 ml. of dibutyl-phthalate in 100 mls. of methyl acetate is added at the rate of 5 gms. per 100 gms. of powder. Rods of 5 x 5 x 15 mms. are moulded from this mass and sintered in air at 1, 240‹ C. for one hour. Table 1 in the Specification gives examples of the impurities such as Si, Te, Co, Cr, Mn, Mg, Pb, Bi, Al, Sn, Ca, Cu, Ag, Na, Zn, As and Cd, which may be present in six different samples of nickel oxide from different sources.

Title: Improvements in or relating to cathode ray television receivers
IPC: H04N3/34
Filed: 1935-01-30
Abstract: 428,926. Television receivers. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ, 12, Place des Etats-Unis, Montrouge, Seine, France. Jan. 30, 1935, No. 3091. Convention date, Jan. 31, 1934. Drawings to Specification. [Class 40 (iii)] In a cathode-ray receiver, a high-frequency oscillation of small amplitude is superimposed on the image-frequency scanning oscillation, so that the cathode ray performs rapid vertical oscillations along each line. The apparent thickness of the line is thereby maintained constant ; and striations, produced by variations in the size of the spot due to modulation, are avoided. The high-frequency oscillation may be the radio-frequency carrier used for transmission, or the local oscillations of a super-heterodyne receiver.
Patent GB-776599-A (GB)
Title: Process for the uniform distribution of liquid substances in mixtures thereof with solids
IPC: B01F3/12
Filed: 1953-02-04
Abstract: Finely divided solids, containing free water, are mixed with liquids immiscible with water by passing the substances to be mixed between co-axial plates, one of which rotates, the other being stationary, the substances being subjected to intense turbulence as they are passed to and through a narrow slit, formed between the peripheries of the discs, by a centrifuging wheel which is aranged between the discs and preferably rotates in a direction opposite to that the plate.  The water film is removed from the solid particles by the friction of the turbulence, and is replaced by the added liquid.  The water is thus separated and is removed from the mixture by centrifuging, screening, drying or distillation.  The invention is of wide application, e.g. the liquid component may be a hydrocarbon such as light or heavy oils, water immiscible alcohols or solvents; or solids in the melted state such as pitches, resins; or molten or dissolved crystalline substances, and the treatment may take place at normal or high temperatures.  Regulating reagents and/or emulsifiers may be added to the mixture and the process may be aided by vibrations, e.g. high frequency acoustic vibrations.  The mixing of coking coals with fuel oils, pitches, tars or asphalts, is particularly referred to, the final coke being suitable as electrode material. The process may be used to combine the coke, finely ground with a binding agent preparatory to a final firing.  Another application is the mixing of a binder with coal dust preparatory to briquetting.  Coke slack may be mixed with a binder and added to coking coal preparatory to coking; and fine-grained ores may be mixed with a binder and added to coking coal and agglomerated preparatory to sintering.  Dyes or colouring substances are mixed with binding agents in the preparation of varnishes.

Abstract: 438,923. Cooling air. BRITISH CELANESE, Ltd., 22, Hanover Square, London. Feb. 1, 1935, No. 3295. Convention date, Feb. 8, 1934. [Class 29] Cool air or other medium that has been used for extracting solvent in the course of the dry method of producing artificial filaments is utilized to cool fresh air by indirect heat exchange therewith, the fresh air being, if desired, used for conditioning the spinning room. The cool air from the solvent-recovery apparatus 11 is led through a tower 13 against a descending stream of water or other liquid and is discharged by a fan 16 to waste, and the water cooled thereby flows into a second tower 22 where it serves to cool fresh air supplied by a fan 29 and delivered through a conduit 33 to the spinning room &c. The water may be recirculated by a pump 26 to the upper tower. A supplemental cooler 34 for the water may be located in a valved byepass pipe 39 between the two towers, and be cooled by brine or other refrigerant. The towers may be fitted with baffles 14, 23, or with bubble plates, and a series of upper towers may be used. Instead of a direct-contact system for the fresh air, an indirect closed pipe system may be used, particularly when liquids other than water are employed between the two towers.

Doffing - arrangements; spindle apparatus. - In doffing - apparatus for spinning, twisting, slubbing, roving and like machines of the kind in which the cap-holder is moved horizontally and also supports the full and empty during their transference, the full and empty bobbins are simultaneously raised from the spinning-spindles 9 and spindles 23 on a rotary bar 17 to holders 26, 25 mounted with the cap-holder on a rack 14, which is moved so as to position the full and empty bobbins in turn over the spindles 23, 9 respectively upon which they are deposited by moving the holders 25, 26 horizontally. The bar 17 is moved horizontally and turned so that the yarn, which is also engaged by fingers on the holders 25, is wrapped around the tubes and is nipped in notches between the tubes and the driving-dogs on the wharls by the empty bobbins, as shown in Fig. 6. The full bobbins are prevented from rotating by means of pins so that the yarn is broken upon restarting. Spring catches 29 may be provided to retain the full bobbins on the spindles 23. The bar 17 is turned so that the spindles 23 project vertically downwards during spinning and is locked in this position by a spring-catch. The caps are gapped at 16 to engage the holders and may be secured to the spindles by means of a metal strip 40, Fig. 11, which engages a flat on the spindle. The gap 16 prevents the creation of air pressure in the cap and thereby tends to prevent fluffing of the yarn.
