Title: Purification of glycerine
IPC: C11D19/00
Filed: 1960-09-02
Abstract: Glycerol, containing contaminants having boiling-points close to that of glycerol, is purified by treating the impure glycerol with hydrogen peroxide at an elevated temperature in the presence of a catalytic amount of an oxygen-containing oxidation catalyst selected from lead peroxide, vanadates, molybdates, tungstates, ruthenium compounds and chromium compounds, and thereafter separating glycerol from the solution.  The impure glycerol may be in solution in water or organic compounds.  Preferably the process is carried out at a temperature of 65-90 DEG C. with from 0,1 to 10% by weight of hydrogen peroxide and 0,001-1,0% by weight of catalyst based on the glycerol.  The glycerol may be separated from the aqueous solution after the oxidation treatment by fractional distillation.  Suitable catalysts are, for example, ammonium molybdate, ruthenium oxide, ammonium meta-vanadate, sodium tungstate and potassium chromate.
Patent GB-727610-A (GB)
Title: Improved process for the preparation of crystalline trypsin
IPC: C12N9/76
Filed: 1952-12-01
Abstract: Crystalline trypsin is obtained by treating enzyme-containing tissues with organic solvents and then reducing the concentration of the latter to 4 per cent or less by volume of the mixture, e.g. by addition of water and preferably also distillation of the organic solvent under reduced pressure; the liquid phase is then separated from the tissues and the trypsin crystallized by standard methods. The process is particularly applicable to pancreas gland residues from which insulin has been extracted. Preferably in the initial treatment 6-14 (e.g. 9-11) parts by weight of extraction solvent are used per part of tissue solids, and the operating temperature is below 30 DEG  C., e.g. 11-20 DEG  C. When the extract is diluted with water this is preferably added in amounts of 6-20 (e.g. 10) parts by weight of tissue solids.  This addition may be step-wise, or alternatively the tissues may be washed with water to produce a solvent concentration of 15-25 per cent by volume, the wash water discarded and the extract diluted with water to the desired degree. The extraction of the enzymes is facilitated by acidifying the organic solvent with a mineral acid, e.g. phosphoric, hydrochloric or sulphuric.  In all the methods the final concentration of organic solvent is preferably 1 per cent or less.  Crystalline trypsin may be obtained from the extract by fractional precipitation with an inorganic salt such as ammonium sulphate.  The process may be combined with that of Specification 727,611 wherein extraction of the enzymes is facilitated by mechanical distortion of the tissues. Examples are given of the treatment of insulin-free beef and pork pancreas. The fat particles are preferably skimmed off after the extract has been diluted, and the remaining solids removed by centrifugation. The trypsin may be extracted in the form of trypsinogen (or chymotrypsinogen).

[Also in Groups II and XXXVI] Closely spaced electrodes on a semi-conductor body are produced by vapour depositing electrode substance in an evacuated vessel on to the body through one or more apertures in a stencil, then moving the stencil in the vessel relative to the body and again depositing through the aperture(s) on an adjacent body region(s). Fig. 1 shows an enclosure in which semi-conductor body 1 is 'held by springs against stencil 4 with aperture 6. The stencil 4 is associated with adjustable stop members 7, 7a which slidably secure it to frame- 2. A weight 10 and lever mechanism acting through rod 8 urges the stencil 18 to one end position where one type of electrode material is evaporated from a dish or capsule 18 on to the semi-conductor through aperture 6. A second weight and lever mechanism 11 is then released by fusing a retaining wire link 14, which urges stencil 4 to its opposite end position where a second evaporation from source 18a can be performed to provide a second electrode adjacent the first. The semi-conductor may be heated during or after the evaporating process to diffuse or alloy the electrode material, heating being effected by passing current through the body via frame 2 or by enclosing the body in a furnace such as that shown in Fig. 2 where current is passed through tantalum or molybdenum metal sheets 23 and 24 which surround the stencil and frame 2 carrying semi-conductor 1. Even heating is provided by having apertures in sheets 23 and 24 to control current flow. A plurality of electrodes on one or more semiconductor bodies may be applied simultaneously and spring and/or magnetic means may be used to effect movement of the stencil. The material of the frame or other apparatus in contact with the semi-conductor may consist of tantalum, molybdenum or nickel. The arrangement is particularly suitable for providing mass transistors having rectifying and ohmic electrodes spaced say 10-20 Á apart. Specifications 874,713, 892,063 and 907,164 are referred to.
