Abstract: 477,386. Paper; barrels, pails, containers, cans, &c. MUSHER, S. March 26, 1936, Nos. 9035 and 9036. Convention dates, March 29, 1935 and March 17, 1936. Drawings to Specification. [Class 96] [Also in Group XVII] Edible products such as bread, lard, margarine, butter, cheese, cream, fish, and fruit are protected against oxidative changes such as rancidity, loss of flavour and discolouration, by the use of packaging materials such as paper, cardboard, wood or metal, with which is incorporated the flour of seeds or grains, in particular oat flour and soya bean flour, or the product obtained by extracting such seeds or grains with molten wax. In the case of paper, cardboard, &c., the flour may be mixed with the pulp from which the paper is made, or it may be dusted on the wet surface of the paper during manufacture, or the paper may be dipped into a suspension of the flour in water, glycerine, &c. More usually, however, the oat flour &c. is applied as a coating in wax, size, or lacquer, this method being applicable also to wood, metal and other surfaces. Where wax or lacquer coatings are normally employed, these may contain the extracted substance or the flour may be included in such normal coating ; alternatively, the normally-coated paper may be furnished with a second coating containing the flour, or the latter may be distributed on the initial coating, and rolled in as by calendering. There may be treated in this manner the caps such as used for ice-cream, butter, &c., the cardboard boxes used for cereal products, the wooden pails for butter, fish, &c., the barrels for holding lard, oil, &c. (in this case the flour is applied and worked into the silicate coating), the cans employed for foodstuffs, the flour being carried by a lacquer coating, and the glass containers having a wax or lacquer coating. The Specification as open to inspection under Sect. 91 refers to the use of " anti-oxidants " generally, and mentions phenols such as hydroquinone and pyrogallol, and substances such as gum guaiac, and lecithin, and includes legumes, grasses, leaves and twigs. This subject-matter does not appear in the Specification as accepted.
Patent GB-492392-A (GB)
Title: Improvements in the manufacture and production of concentrated nitric acid and ammonium sulphate
IPC: C01C1/24
Filed: 1937-03-30
Abstract: Concentrated nitric acid and ammonium sulphate are obtained by subjecting the dilute sulphuric acid, obtained in the concentration of aqueous nitric acid by means of concentrated sulphuric acid, while it is still hot to a partial or complete neutralization with ammonia, and supplying the vapours thus formed to the concentration or denitration apparatus instead of corresponding amounts of fresh steam.  The ammonia may be introduced directly into the lower part of the concentration or denitration apparatus, or alternatively, the hot effluent dilute sulphuric acid may be treated with ammonia outside the column, the vapours formed being supplied to the column.  It may be necessary to neutralize only a part of the sulphuric acid with ammonia, the remainder of the acid being branched off before the neutralization for other uses.  Or the whole of the sulphuric acid may be neutralized in stages, the vapours necessary for the nitric acid being produced in the first stage and the vapours produced in the second stage being otherwise used, e.g. for the preliminary concentration of dilute nitric acid or for the evaporation of the ammonium sulphate solution.  When only a proportion of the ammonia necessary to neutralize the sulphuric acid is supplied directly to the lower part of the concentration apparatus, the solution of ammonium bisulphate or polysulphate in sulphuric acid may be completely neutralized to ammonium sulphate outside the tower. Alternatively, the acid solution may be freed from bisulphate and polysulphate by cooling and filtration, the resulting salts only being completely neutralized and the dilute sulphuric acid being used for other purposes.

Each coupling 40 is stamped from thin sheet phosphor bronze and the limbs are formed with cylindrical grooves 46, 47 having the same radius of curvature as that of the stylus arms.
Patent GB-754384-A (GB)
Title: Improvements in or relating to methods of testing in metallurgical processes
IPC: G21H5/02
Filed: 1954-03-29
Abstract: A method of determining the quantitative changes in concentration of elements in metal baths of known analyses is characterised in that radioactive isotopes of the element to be determined are added to the melt and their intensities of radiation are measured during the course of the treatment. Preferably sufficient isotope is added to give, with beta radiation, an amount of radiation per ton of pig iron of about 1 mC. or with gamma radiation below 1 mC.  For determination of p  phosphorus the 32P isotope may be used, preferably red phosphorus which has been partly converted to radioactive phosphorus by irradiation.  The isotope may be melted with iron to form iron phosphide.  The iron phosphide is then melted with Thomas pig iron and carbon to give a regulus with a melting point below the temperature of the pig iron to which it is to be added before or in the mixer.  Different elements can be determined simultaneously by using isotopes which are characterised and distinguishable by different peak energies.

Filed: 1924-04-11
Abstract: 237,952. Dowling, J. J. April 11, 1924. Light, control of signalling and other apparatus by.-Thermionic indicating means responsive to light variations comprises an interrupted beam of light falling on a photo-electric cell operatively associated with a thermionic amplifier so arranged that the indicating means is rendered operative, if the cell is not effected by the regularly interrupted light beam, by a relay under the control of the valve system and of a battery independent of the valve system. Fig. 1 shows a light beam source 1, rotating disc 4 with apertures 3, lenses 2, 6 influencing a selenium cell 7 connected to an audio-frequency amplifier to affect a moving coil relay 12 having a biasing current from battery 17 and a regulating resistance 18. The light rays may be brought to a focus by the lens 6 in front of a screen or diaphragm 11 arranged in front of the cell 7. Fig. 4 shows a modified amplifier in which the cell 7 is arranged in series with an equal resistance 47 and the potential is applied to the grid of the valve through a condenser 45. In a further modification a clockwork or other mechanically driven switch is employed to disconnect the batteries except for a brief period at intervals so as to economise battery power. In this modification the moving coil relay influences a second relay so arranged that the signal or indication given by the apparatus is unaffected by the current interruption. The apparatus may be employed to detect haze or fog and a colour screen or cells sensitive to special regions of the spectrum may be used. It is also applicable to detecting smoke or turbidity in liquids or for recording the passage of objects. A recording galvanometer may be used instead of, or in addition to, the relay 12.
