Patent GB-487367-A (GB)
Title: Preparation of vitamin concentrate
IPC: A61K31/59
Filed: 1937-09-17
Abstract: In the extraction of vitamins from marine animal oils such as cod liver oil, a high vacuum distillate of the oil is saponified to at least 33,3 per cent, and the unsaponified fraction is separated and treated by high vacuum short path distillation.  The vitamin-containing fraction may be separated from the saponification mixture by means of an added solvent which may be a mixture of fatty glycerides, or may be separated mechanically, the vitamins being then in solution in the unsaponified portion of the oil.  The saponification may be effected by caustic potash or soda, ammonia, or lime, and an alcohol such as methyl or ethyl alcohol may be added to assist the saponification.  After the saponification, hot water and a solvent are added.  The solvent may be a fish oil from which the vitamin fraction has been separated, or the fish oil itself.  If desired, when the initial oil is vacuum-distilled the fraction which contains the high-boiling (ester) forms of vitamins A and D and comes over at 190-200 DEG  C. (compared with quinizarin green at 220 DEG C.) may be separated as fit for immediate therapeutic use, while the fractions coming over at 150-190 DEG  C. and 200-260 DEG  C. may be treated according to this invention; the vitamins recovered from these fractions will be in the low-boiling (alcohol) form.  A detailed example is given of the treatment of a cod liver oil fraction.  Other fish oils such as halibut liver, tuna and salmon oils may be used.  Specification 479,802, [Group III], is referred to.

Patent GB-655912-A (GB)
Title: Manufacture of condensation products primarily intended for use in the treatment of textile materials
IPC: D06M15/423
Filed: 1948-09-30
Abstract: The condensate obtained by reacting an organic acid amide with glyoxal to substitute part of the reactive hydrogen atoms followed by further reaction with formaldehyde to substitute the remainder as described in Specification 655,193, [Group XL (c)], is modified by further condensation in an acid medium with not more than molar proportions of a monohydric fatty alcohol having more than 10 carbon atoms, preferably 15-20 carbon atoms; the reaction is preferably carried out in the presence of an emulsifier, e.g. a sulphonate of the fatty alcohol used in the condensation or an ethylene oxide-alcohol condensate; alternatively a solvent for fatty alcohols but inert to methylol groups may be present, e.g. N-methyl pyrrolidene, dimethyl or methylol formamide.  Immersion in aqueous solutions of the modified condensate gives fabrics water repellency characteristics and resistance to washing with soap and sodium carbonate.  In the example, 1.5 kg. urea is dissolved in 5.8 kg. glyoxal; the mixture is acidified with HCl and boiled; the precipitate obtained is reacted with alkaline 30 per cent formaldehyde and boiled until all formaldehyde is combined; 0.05 kg. sulphonated n-octadecyl alcohol is added to the product which is then neutralized with caustic soda lye; a further 0.54 kg. of n-octadecyl alcohol are added while refluxing and finally 0.75 per cent of the condensation product of ethylene oxide and the alcohol and some paraffin.  The mixture is emulsified and cools to a homogeneous paste which, diluted with water and mixed with ammonium nitrate, is used as the textile bath.ALSO:Textiles are treated with the condensate obtained by reacting an organic acid amide with glyoxal and formaldehyde as described in Specification 655,913, [Group XL (c)], but modified by further condensation in an acid medium with not more than molar proportions of a monohydric fatty alcohol having more than 10 carbon atoms, preferably 15-20 carbon atoms; the reaction is preferably carried out in the presence of an emulsifier, e.g. a sulphonate of the fatty alcohol used in the condensation or an ethylene oxide alcohol condensate; alternatively a solvent for fatty alcohols but inert to methylol groups may be present, e.g. N-methyl pyrrolidine, dimethyl or methylol formamide.  Immersion in aqueous solutions of the modified condensate gives fabrics which are not only resistant to shrinking but have water-repellent characteristics, these properties being resistant to washing with soap and sodium carbonate.

Abstract: 435,956. Tea-rolling machines. BEVER, A., and NEWTON, CHAMBERS, & CO., Ltd., Thorncliffe Ironworks & Collieries, near Sheffield. Sept. 6, 1934, No. 25670. [Class 129] In a tea-rolling machine having a horizontal table over which is arranged a canister for the tea leaf, means are provided for varying the pressure on the canister cap. The mechanism for applying or relieving the pressure is controlled by the machine itself during the rolling operation. In the form illustrated, as the crank 1 is rotated to give the table rotary movement, the cam shaft 14 is also rotated at a much less speed. As the cam projections 23 and depressions 25 bear on the rollers 27, the levers 30 and rod 31 are moved to alter the drive of the pressure screws in order to apply or release the pressure applied to the leaf during rolling. The shaft 29 also carries an arm 33 with a weight or spring to keep the rollers 27 in contact with the cam faces. The end plate 8 carries an electrical contact device 34 to ring a bell after each machine cycle.

Abstract: 644,857. Protective cut-out systems. KESL, K. Aug. 29, 1946, No. 26013. Convention date, April 18, 1944. [Class 38(v)] When the electric supply system in a large building is over-loaded the less important circuits B are disconnected before the main switch A<SP>1</SP> is tripped. Circuits A, B on floors I, II are supplied through contacts Ka, Kb of relays Sch 1, Sch 2. When a relay holding electromagnet M is de-energized by a thermal overload element T<SP>2</SP> in the circuit B thereby opening contacts K<SP>1</SP>, the more important circuit A is restored after a pause by a dash-pot ZL reclosing contacts Ka leaving the circuit B open at contacts Kb. However, if the magnet M is de-energized by thermal or electromagnetic overload devices T<SP>1</SP>, E³ in the common circuit A, B opening contacts K<SP>1</SP>, K<SP>2</SP>, a snap-member z, previously acting as a stop, moves to latch the lever carrying contacts Ka, Kb and contacts Ka remain open. The contacts Ka may be short-circuited if momentary interruption is undesirable. On overload in the main, all magnets M are de-energized by the opening, by a thermal element Th of a transformer-rectifier circuit TR,E. If the overload persists, the element Th continues its movement and trips the switch A<SP>1</SP>. The circuit on Floor III is normally supplied through contacts K<SP>3</SP> of an electromagnetic switch, but when its coil M is de-energized by thermal elements Tp or Th, the current is limited by a shunt automatic switch A<SP>2</SP> having a lower current rating. A time-switch Z may deenergize all windings M for peak loading hours every day.

Title: Improvements relating to processes for decomposing lignin
IPC: C08H5/02
Filed: 1954-09-10
Abstract: Distillable phenolic products are formed by the decomposition of lignin by a continuous treatment with hydrogen at above 350 DEG  C. and at a pressure of at least 30 atmospheres in the presence of a catalyst consisting of an iron salt containing sulphur in the anion. A thin paste or sludge of lignin, the catalyst and a high boiling liquid such as xylenol is continuously passed with hydrogen through a reaction chamber at reaction temperature and pressure, the reaction mixture being cooled immediately after leaving the chamber.  The hydrogen is separated and recycled and the liquid products are distilled to give an oil containing phenols.  The catalyst may be a sulphate, sulphite or sulphide of iron such as ferrous sulphate.  The catalyst after recovery is partly in oxide form and partly in sulphide form and this mixture may exert a catalytic effect.  The process may be effected using lignin from the Scholler wood saccharification process or from the waste liquors from the sulphate cellulose process, any sulphuric acid contained in the lignin being neutralized with lime.  In examples (1) Scholler lignin mixed with quicklime, 2.5 per cent of ferrous sulphate calculated on the lignin, and xylenol in the form of a thin paste, is heated under 700 atmospheres pressure and 380 DEG  C. with hydrogen, the liquid products distilled after removal of calcium sulphate and catalyst by filtration to give an oil containing phenols and the hydrogen recycled; (2) and (3) illustrate the same process using (2) a larger proportion of catalyst and (3) a lower pressure.  Specification 756,283 is referred to.
