Title: Improvements in the manufacture and production of coloured masses or solutions of the same
IPC: C08K5/00
Filed: 1927-02-24
Abstract: 293,067. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 24, 1927. Lakes; azo, azine, triphenylmethane, oxazine, thiazine, and rhodamine dyes.-Coloured masses containing cellulose esters or ethers, or artificial or natural resins, including condensation products of urea and formaldehyde, and solutions thereof in organic solvents, such as lacquers or varnishes, are obtained by incorporating with the said masses or solutions, the salts formed by dyes containing sulphonic or carboxylic groups with organic derivatives of ammonia in which the ammonia-nitrogen atom is not bound to such a carbon atom as is itself directly connected with two other atoms of nitrogen. Suitable bases are alkylamines and their derivatives such as ethylamine, dimethylamine and di- and tri-ethanolamine; arylalkyl- and arylamines, such as dimethylaniline, xylidine, and pseudocumidine; hydroaromatic amines, such as cyclo- and dicyclohexylamine; heterocyclic bases, such as pyridine, piperidine, and quinoline : and bases of dyestuffs, such as those of the triphenylmethane, azine, thioazine and oxazine classes. The salts may be added to the finished masses or solutions, or incorporated at any stage in their manufacture ; the dye salts may also be produced within the masses or solutions by dissolving therein the dye sulphonic or carboxylic acids and the bases, in succession or simultaneously. In examples, (1) the salts obtained from dicyclohexylamine, Auramine base, or Victoria blue base and the disazo dye from dianisidine and 1 : 8-aminonaphthol-2 : 4-disulphonic acid are used to colour an ordinary nitrocellulose lacquer in various shades of blue; (2) the piperidine salt of the azo dye from 4-chloraniline-3-sulphonic acid and diphenylamine is used to colour an alcoholmanila copal lacquer greenish-yellow; the cyclohexylamine salt of the dyestuff from aminoazobenzene and 2-naphthol-6:8-disulphonic acid gives a scarlet lacquer, (3) the disazo dye from benzidine and 1 : 8-aminonaphthol-2 : 4-disulphonic acid is dissolved in a nitrocellulose lacquer and dicyclohexylamine is added ; a bright blue lacquer with a reddish tinge is obtained, (4) a brilliant red lacquer is obtained by dissolving the benzylaniline salt of the dye from p-aminoazobenzene and 2-naphthol-3 : 6 : 8-trisulphonic acid in a nitrocellulose lacquer, and (5) a violet dye, easily soluble in organic solvents, in particular in alcohols and in nitrocellulose, or resin lacquers, is obtained by precipitating Rhodamine B with the sodium salt of the azo dye from ethylp-phenylenediamine and chromotropic acid; the product from Rhodamine. B and the azo dye from aniline and the product obtained by treating H- acid with p-toluene sulphochloride gives bluish-red shades, and that from Sairanine and the azo dye from 2 : 5-aminonaphthalene sulphonic acid and p-cresol colours nitrocellulose lacquers in yellowish-red shades.

Patent GB-668904-A (GB)
Title: Glass feeder
IPC: C03B7/16
Filed: 1950-03-06
Abstract: 668,904. Glass. CORNING GLASS WORKS. March 6, 1950 [March 11, 1949], No. 5623/50. Class 56. Moulds are charged with glass by issuing a stream of molten glass from a supply body, increasing the rate of issuance of glass from the body to form a mould charge in the stream, severing the stream from the supply body immediately before the formation of the mould charge therein, and again severing the stream from the supply body immediately after the formation of the mould charge therein. The invention is particularly for use when charges are required at long intervals or irregularly, which normally would be impracticable because of the chilling of glass near the extrusion opening. It is described as applied to the usual foreheath 11 having a bottom extrusion opening 22 controlled by an axially movable vertical needle 12. The needle is arranged so that a stream of glass issues continuously from the opening 22, the chilling of the glass near the opening 22 being thus avoided. When the needle is raised to initiate the formation of a charge, the shears sever the stream from the supply, and when the needle has substantially completed its charge-extruding movement, they are again operated to sever the charge from the supply. The arrangement is substantially as described in Specification 227,078, [Class 56], the cam 25, which, with the needle-actuating cam 20, is on a shaft 26, being modified to effect two operations of the shears for each reciprocation of the needle. The shaft 26 is driven, through worm gearing, from a shaft 27 coupled by chain gearing 28 to a countershaft 30. A motor 33 drives the shaft 30 through a clutch 31 whenever the clutch control cam 32 is freed for rotation. The cam 32 is normally held against rotation by a spring-urged bell crank 34, 34a, a magnet 37 being momentarily energized to free the arm 34a from the cam. The bell crank is then held away from the cam by a spring-urged lever 41 which engages the arm 34 until the shaft 30 has made sufficient revolutions to produce one revolution of the shaft 26. The magnet 45 is then energized, by an arm on the shaft 26 closing contacts 46, and the bell crank is released to engage the cam 32.

Filed: 1974-02-08
Abstract: 1468091 Recovering fatty substances from aqueous effluents APOTHEKERNES LABORATORIUM FOR SPECIALPRAEPARATER AS 8 Feb 1974 [9 Feb 1973] 05893/74 Heading C5C [Also in Divisions C1 and C3] Fatty and/or proteinaceous substances are recovered from aqueous effluents by adding an acid hydrolysing metal salt to complex with the substance, reducing the pH to 5 or below if it is above 5, and precipitating the complex in the presence of added alkaline earth metal ions by raising the pH to 6 or more. The acid hydrolysing salt can be ferric sulphate, ferric chloride or aluminium sulphate. The pH can be reduced by adding mineral acid such as sulphuric acid. A calcium salt can be added in aqueous solution together with the acid hydrolysing salt to provide the alkaline earth metal ions and the pH can be raised by alkali metal hydroxide; alternatively CaO or Ca(OH) 2  can be added to both provide the alkaline earth metal ions and to raise the pH. The precipitated complex can be separated from the purified effluent by flotation achieved by the release of air dissolved in the water under pressure, sedimentation or centrifugation. The examples describe the treatment of effluents from a margarine factory, a tallow melting plant and a slaughterhouse. The precipitated complexes are resistant to autoxidation and can be included in animal fodder mixtures.

Title: A system of protection for liquid-insulated electrical apparatus
IPC: H02H5/06
Filed: 1937-02-27
Abstract: 482,634. Protective cut-out arrangements; fiuid-actuation of switches. BUCHHOLZ, M. Feb. 27, 1937, No. 5972. [Class 38 (v)] Liquid-insulated electrical apparatus incorporates protective means within a casing of the apparatus including a detector mechanically operated by gases or vapours. or air and also separate detector means responsive to changes in temperature, each of said protective means being adapted to operate signalling or switch devices. In Fig. 8, the chamber 22 is housed on the top of, and normally separated by a flap 24 from, the apparatus chamber, the flap being pivoted at 23 and carrying a switch tube 7. A thermal capsule 12, heated by a coil 26 in dependence on the load current in the apparatus, is adapted to raise the flap and as the flap is also raised by production of gas on fault in the apparatus, the response of the switch will be more rapid the greater is the load. Figs. 5, 6, 9 show forms in which the device is housed in the pipe between the apparatus and its expansion vessel, a float 5 being pivoted at 6 to respond to drop of liquid-level caused by gas-accumulation in the housing, and a float 2 being pivoted at 3 to respond to violent agitation in the liquid produced by gas-formation. In Fig. 6, the capsule 12 acts to depress the float 2 so that operation of the latter to close contact 14 is more rapid the greater the temperature of the liquid and, therefore, of the apparatus. In order to show which cause has produced operation, the capsule also operates a visual indicator comprising a fixed slotted disc 17 provided at the back with a movable disc 18 with horizontal coloured lines. In Fig. 5, the capsule 12 acts on a member 16 which is pivoted at 3 and after a given angular rotation engages the float and moves it against contact 14. In Fig. 9, one end of a bimetal spiral 8 is attached to the float and the other end carries a mercury switch 15. In another form, Fig. 7 (not shown), a capsule engages a slide valve in the pipe itself and so offers a larger passage to the liquid as the temperature increases, and at a given maximum temperature, the valve closes a relay circuit. The Specification refers also to the use of a battery of capsules, to acoustic signals, and to Specifications 273,701 and 293,705, [both in Class 38 (v)].
