Patent GB-755043-A (GB)
Title: Process for the production of cyantetrazole, ditetrazole and tetrazole carbamide and the salts thereof
Filed: 1954-04-29
Abstract: Cyanotetrazole, tetrazole carboxylic amide and ditetrazole (or salts thereof) are obtained by reacting hydrogen cyanide and hydrazoic acid in aqueous solution in the presence of a copper salt and/or another oxidizing agent such as manganese dioxide, potassium permanganate, hydrogen peroxide, chromic acid or a ferric salt.  Sodium cyanide and azide may be used instead of the corresponding acids.  The reaction occurs between one mol. of azide and two mols. of cyanide but if no other oxidizing agent than a copper salt is present a further two mols. of cyanide are necessary to form cuprous cyanide.  The initial product (below 30 DEG  C.) is cyanotetrazole, but at higher temperatures (90-100 DEG  C.) this absorbs a mol. of water to give tetrazole carboxylic amide. Ditetrazole is obtained by using one mol. of azide to two mols. of cyanide and an excess of copper sulphate and gradually raising the temperature to 90-100 DEG  C.  The products are usually obtained as insoluble metal salts, e.g. copper or manganese, the free tetrazole derivative being obtained on acidification.  The amide gives sodium tetrazole carboxylate on treatment with caustic soda and tetrazole itself can be obtained from the amide or acid salt by treatment with acid.  Examples show the production of (1) cyanotetrazole (purified as copper or silver salt) from sodium cyanide, sodium azide, manganese dioxide, sulphuric acid, copper sulphate and formic acid in the cold; (2) ditetrazole (as manganese salt) from the same reagents at 90-95 DEG  C., using acetic instead of formic acid; (3) ditetrazole and tetrazole carboxylic amide (as manganese salts) from the reagents of (2) heated in the absence of acetic acid; (4) cyanotetrazole (sodium salt) from sodium cyanide, sodium azide and copper sulphate at 40-45 DEG  C.; (5) ditetrazole (as manganese salt) from sodium cyanide, sodium azide, manganese dioxide, sulphuric acid and formic acid.
Patent GB-959465-A (GB)
Title: Abrasive fabrics
Inventor: HERMANCE HAROLD WALTERS
IPC: A47L13/06
Filed: 1961-04-07
Abstract: <PICT:0959465/C3/1> An abrasive pile fabric having piles of thermo-plastic fibrous material, the outer ends of which fibres have been fused, comprises either (a) abrasive particles which have been bonded by heat to the outer ends of the fibres of the pile, or (b) self-abrasive caps which have been formed by fusing together the outer ends of tufts of the individual fibres.  The pile fabric comprises such thermoplastic fibrous material as cellulose acetate, ethylene glycol-terephthalic acid polyesters, polyacrylonitrile, copolymers of vinyl chloride and vinyl acetate, copolymers of acrylonitrile and a vinyl derivative, or copolymers of sebacic acid and hexamethylenediamine. Abrasive fabric (a) is produced by depositing abrasive particles on to the face of a pile fabric and heating the fabric so as to fuse the outer portions of the thermoplastic pile fibres, and finally cooling.  It is preferred that a segment of the outer portion of the pile fibres be heated to a temperature which is at least above the distortion point of the thermoplastic material but below its decomposition temperature so that the segment is distorted over 10 to 30% of the overall fibre length. The pile fabric which is used includes such materials as terry cloth, velours, velvets, chenilles, and all tufted and/or napped fabrics which have cut or uncut loops, fibres, or tufts of fibres extending in a direction and substantially normal to the plane of the warp of the fabric. Suitable abrasives include alumina, silica, garnet, diamind, pumice and silicon carbide, As shown in Fig. 1, a suitable apparatus by which such abrasive-containing fabrics may be obtained comprises drag rollers 2 through which pile fabric 1 is pulled by means of drive rollers 3.  Abrasive particles 4 are deposited on the pile fabric 1 by means of a dusting box or other device (not shown) and the fabric then passes under heating element 5 so positioned that the outer or upper portions of the fibres of the pile are heated causing them to fuse.  As the fabric 1 leaves the vicinity of element 5, the fused portions of the pile cool and solidify.  The abrasive-containing fabric 7 then passes through vacuum nozzle 8 which removes excess abrasive particles not bonded to the pile fibres; the upper portions 13 of tufts the fibres are obtained in the form of fused bulbous masses or caps 12 which contain abrasive, as shown in Fig. 3.  Self-abrasive fabrics (b) are obtained by omitting the abrasive and have fused caps 15 as shown in Fig. 4. These self-abrasive fabrics are of particular application in the manufacture of rotary scrubbing units suitable for cleaning step-by-step switches of the type commonly used in telephone exchanges (see Division A4).  U.S.A. Specification 2,843,869 is referred to.

Title: Improvements relating to the preparation of therapeutic substances from tubercle bacilli
IPC: A61K39/04
Filed: 1928-05-02
Abstract: 320,048. Saisho, I. May 2, 1928. Immunizing and like serums.-Preventive and remedial preparations are obtained from tubercle bacilli by removing the wax therefrom by treatment with strong hydrochloric or sulphuric acid for a short time. The remaining albuminous portion of the bacilli is suspended in a physiological salt solution containing 0.5 per cent phenol for use as an injection. According to an example the bacilli are collected on a filter paper, ground in hydrochloric acid of 20 to 37 per cent concentration for 5 to 10 minutes, separated from the acid in a centrifugal machine with or without previous dilution of the suspension with salt solution, and the precipitate washed with salt solution and finally made into a suspension for use. Hydrochloric acid may be replaced by sulphuric acid of 60 to 94 per cent concentration, in which case the required material collects on the surface of the acid instead of being precipitated. Freedom of the preparation from wax may be tested by staining with carbolic fuchsine, decolorizing with alcohol containing hydrochloric acid, and again staining with methylene blue. Waxy material may be separated from the acid solution by extraction with chloroform or Ether. A process for removing wax from tubercle bacilli by prolonged treatment with dilute acid is also referred to.
