Patent GB-314532-A (GB)
Abstract: 314,532. Boehringer, A., (trading as Boehringer Sohn, C. H.). June 29, 1928, [Convention date]. Lobeline, lobelanine, and lobelanidine.-The alkaloids of lobelia have been found to have the following structural formulae, viz. :- Lobeline and lobelanine can therefore be produced by oxidation of lobelanidine and the opposite reactions may be effected by hydrogenation of lobeline and lobelanine. The oxidation of lobelanidine may be effected with the usual oxidizing agents such as permanganate in sulphuric acid or chromic.acid in glacial acetic acid, the oxidation being controlled so as to give the desired product; when lobeline is the product desired, any lobelanine produced may be converted into lobelanidine by catalytic hydrogenation, this product then oxidized to obtain lobeline. In examples, (1) lobelanidine is dissolved in dilute sulphuric acid and treated cold with potassium permanganate, the reaction mixture being finally made alkaline, filtered, and extracted with ether; the ethereal extract is concentrated to obtain first unchanged lobelanidine, then lobeline, and on complete evaporation an oily residue which is dissolved in acetone and treated with concentrated nitric acid, yielding lobelanine nitrate from which by hydrogenation lobelanidine is obtained as above mentioned: (2) the lobeline obtained as above described, which is optically inactive, may be resolved into its optically active components by means of suitable optically active acids or their salts, for instance lobeline hydrochloride may be treated with sodium tartrate yielding the tartrate of l-lobeline as a light oil which soon sets, while the d-lobeline is recovered from the mother-liquor. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an example in which the oxidation is effected with pyrolusite (freshly precipitated) and the extraction with chloroform; the solution is evaporated to dryness and the residue dissolved in ether. This subjectmatter does not appear in the Specification as accepted.

Abstract: 507,664. Bleaching cellulose fibres. HUGHES, C. L. (Buffalo Electro-Chemical Co., Inc.) Nov. 16, 1937, No. 31489. [Class 15 (ii)] Bleaching of cellulosic fibres, natural or artificial, including paper pulp, is effected by saturating them with a solution containing, per litre, at least 20 cc. of hydrogen peroxide, 30 per cent by volume, or equivalent amounts of per-compounds normally generating hydrogen peroxide in solution, and an alkali content equivalent to at least 5 grams of caustic soda; the solution being maintained at room temperature, i.e. up to 125 F., and the goods being permitted to bleach without any substantial evaporation of the solution.

Title: Lubricating apparatus
IPC: F16N3/12
Filed: 1923-12-17
Abstract: 230,903. Zerk, O. U. Dec. 17, 1923. Single-acting suction-valveless piston pumps; delivery spouts; suction reservoirs.-Leak-prood contact between the nozzle 12 of a lubricant gun and a lubricating nipple 17 is obtained by forming the nozzle with a concave end surface 15 adapted to embrace the circular edge 16 of the nipple, a flared guiding surface 14 being provided. Alternatively, the concave surface may be formed on the nipple. The gun comprises a barrel 1 on which is threaded a head 6, in the tapered end of which is telescopically mounted a tube 11 carrying the nozzle 12, in which a check valve 23 is fitted. A perforated partition 30 secured in the head 6 forms an abutment for a plunger 35 sliding in the tube 11. A spring 37 is arranged between the head 36 of the plunger and a washer 28 held against a shoulder on the tube 11, outward movement of the tube being limited by a washer 39 secured thereon. The barrel 1 contains a piston 40. In operation, the face 15 of the nozzle is placed in contact with the rim 16 of the nipple and pressure is exerted on the barrel 1 towards the nipple. The head 6 telescopes over the tube 11. causing the plunger 35 to move into the tube 11, closing the inlet port 26 and ejecting a charge of lubricant from the tube into the nipple. The pressure on the barrel towards the nipple maintains the leakproof connection, even though the nozzle is presented angularly to the nipple. When the pressure is released, the spring 37 moves the tube 11 outwards, the vacuum produced therein causing a fresh charge to be drawn into the tube when the port 26 is uncovered, the piston 40 being also moved forward by atmospheric pressure acting through a hole 51 in a cap 2. The nozzle may be mounted on the end of a flexible tube leading from a gun. Reference has been directed by the Comptroller to Specifications 218,639 and 218,640.

Title: Improvements in metallurgy
IPC: C22B3/08
Filed: 1947-12-01
Abstract: In a process for recovering iron from ferrous sulphide-bearing material involving treatment of the ferrous sulphide material with aqueous sulphuric acid to produce ferrous sulphate solution, the ferrous sulphate solution is either heated to above, say, 90 DEG  C. or cooled to below say, 25 DEG  C. to form solid ferrous sulphate which is separated from the mother liquor, and the mother liquor, with added sulphuric acid and, if necessary, water, is used for the treatment of further sulphide-bearing material.  Ore containing iron sulphide is smelted and the resultant matte is treated countercurrent with acid at, say, 50-70 DEG  C. to produce (1) hydrogen sulphide, (2) a solid residue of sulphides of cobalt, copper, gold, nickel, platinum, silver, zinc, (3) a neutral saturated solution of iron sulphate.  The solid ferrous sulphate is separated by decantation or filtration.  The zinc may also be recovered as sulphate by crystallization from an intermediate stage.  Specifications 566,375, 656,141 and 656,143 are referred to.

Abstract: 937,729. Finishing yarns. SDRUZENI PODNIKU TEXTILNIHO STROJIRENSTVI. Sept. 5, 1961 [Sept. 7, 1960], No. 31832/61. Class 120 (3). In the operation of a bulking device, yarn 13 passes through an opening 4 into an expansion chamber 5 where it meets a pressure screen created by guiding thereto a pressure creating fluid medium, e.g. air, through openings 8 from a distribution chamber 6. In consequence of a reduction in the rate of travel of the yarn, the moment it passes through the screen, and the expansion of the fluid, the yarn is loosened and, as a result of tangential flow of fluid from openings 8 into chamber 5, the yarn is also partly untwisted. The yarn, in this condition, is bulked under the direct effect of symmetrical fluid currents discharging from openings 8 with resultant turbulence of fluid in chamber 5. The distance between the place at which openings 8 meet chamber 5 and a discharge opening 11 is at least twice the diameter of the chamber so that there is no interference with the screen. Bulked yarn emerging from the device may impinge on an inclined baffle 12 in order to render the bulking loops uniform in size.
