Title: Roller bearing
Inventor: DAVIS RALPH NORMAN
IPC: F16L27/08
Filed: 1959-04-24
Abstract: 907,194. Bearings. BRISTOL SIDDELEY ENGINES Ltd. April 25, 1960 [April 24, 1959], No. 14128/59. Class 12 (1). [Also in Groups XXVIII and XXXIII] A bearing for a pair of relativelyrotatable coaxial gas-duct members 10, 11 for example, has a race attached to each of the members so that on assembly an annular channel 22 of square cross-section is formed. Each race has two bearing surfaces inclined at right-angles to one another so that rollers 25 may be assembled in staggered formation. The members 10, 11 carry annular brackets 12, 13 extending into overlapping axial flanges 14, 15 and carry radial flanges 16, 17 having circumferentially-spaced holes 30 therein. A flanged member 20 which forms the inner race is attached to the flange 17 by bolts 18, and a flanged member 21 which forms the outer race is attached to the flange 16 by studs 19. The member 20 is grooved to receive sealing rings 26, and spacers 27 may be provided between the rollers. Because the duct members convey hot gas the bearing is cooled by supplying coolant gas from an annular manifold 28 supported by the bracket 12. The coolant gas passes through the holes 30 in the flange 16 and enters the annulus 29 to be deflected by a plate 32 towards the inner race after which the coolant gas escapes through the annular gap between the flanges 14, 15 and enters the hot gas stream in the duct members. The pressure of the coolant gas forces the races together, the duct 11 is rotated by means of a driving-chain 35 attached by draw-bolts 36 &c. to the flange 17 which has a chain-channel 41 secured thereto. The chain is driven by a sprocket 43 on a shaft 44 which is in a housing 45 attached to a radial flange 46 extending from the fixed outer race. The rollers may be made of phenolic resin.
Patent GB-565566-A (GB)
Title: Improvements in or relating to the production of sulphonamide derivatives of nitro- and amino guanidines
Filed: 1942-10-08
Abstract: Sulphonamido derivatives of nitro- and amino-guanidines having the formula <FORM:0565566/IV/1> where X may be amino, or substituted amino, or a group which is readily convertible into an amino group such as a nitro, acylamino, halogen or azo, and G is a nitro or amino guanidine are prepared by reacting a p-X-benzenesulphonyl halide with a nitroguanidine and, if desired, reducing the product.  The reaction is carried out in a solvent such as acetone, isopropyl alcohol, tertiary butyl alcohol, or dioxane.  Preferably, a basic agent should be present to combine with the hydrogen halide evolved.  With acids the compounds form salts which are soluble in water.  The reduction process to convert the nitro group into amino is carried out using a metal such as zinc.  In examples: (1) nitro-guanidine is added to an aqueous-acetone solution of sodium hydroxide.  An acetone solution of acetylsulphanilyl chloride is added, the temperature being kept below 13 DEG  C.  The product is purified by dissolving in ammonium hydroxide and reprecipitating with hydrochloric acid.  (2) The acetylsulphanilylnitroguanidine prepared in example (1) is reduced to the corresponding amino compound by treatment with iron powder and acetic acid.  (3) The acetylsulphanilylaminoguanidine prepared in example (2) is refluxed with concentrated hydrochloric acid to give the free sulphanilylaminoguanidine.  (4) The acetylsulphanilylnitroguanidine prepared in example (1) is hydrolysed by refluxing with concentrated hydrochloric acid to form sulphanilylnitroguanidine.  In place of the acetyl derivatives referred to above, there may be used other acyl derivatives, such as propionyl, butyryl, benzoyl and nicotinyl.  If desired, p-nitrobenzenesulphonyl chloride may be used in example (1), and in this case the amino compound is formed at the same time as the reduction of the nitroguanidine part of the molecule.  The compounds of the present invention are bacteriostatic and are used as chemotherapeutic agents.  They may also be used as intermediates in the preparation of azo dyestuffs.
