Title: Friction shock absorbing mechanisms
IPC: B61G9/10
Filed: 1947-06-12
Abstract: 625,720. Vibration-dampers; draw-gear. MINER, Inc., W. H. June 12, 1947, No. 15525. Convention date, Feb. 24, 1941. [Classes 103 (v) and 108 (iii)] In a friction shock-absorber comprising a plurality of friction shoes surrounding a pressure-transmitting wedge-member, and having frictional' engagement in a shell, and wherein a spring opposes inward movement of the shoes relative to the shell, the angle of inclination of a wedge face and its co-operating shoe face to the longitudinal axis of the shell is different for each wedge face and its co-operating shoe face. In the arrangement shown, as applied to a railway coupling, the shockabsorber is disposed within a yoke 14, connected to a coupler shank 13. The yoke is supported by a detachable saddle-plate 16 fixed to the bottom flanges of longitudinal sidemembers 10, and comprises a combined friction shell and spring cage A of substantially hexagonal cross-section, a wedge B, friction shoes C, D, E, springs 28, 29 and a bolt G. The wedge faces of the shoes 122, 123, 124 co-operate with correspondingly-inclined face 22, 23, 24 of the wedge B and the outer friction surface 25 of each shoe engages two adjacent inwardly-converging friction surfaces 20, 20 of the shell A. The angle of inclination of the 11 co-operating faces 23, 123 is intermediate those of the faces 22, 122 and 24, 124. During a pulling action the yoke 14 pulls shell A towards a front follower 15, the follower being held against stop lugs 11, 11. During a buffing action the front follower, which bears against the front face of the wedge, forces the latter inwardly of the shell against the springs 28, 29, the shell being held against stop lugs 12, 12. Movement of the wedge and shoes during either of these actions is such that initially the wedge and shoes C and D move inwardly of the shell in unison and slightly ahead of shoe E, due to the smaller angle of inclination of the cooperating faces 24, 124 of the wedge and the shoe E. Further inward movement of the wedge causes " slip " between the wedge and shoes C and D, due to the relative non-wedging angle of the shoe and wedge faces 22, 122 and 23, 123 which, together with the effect due to the tapering of the friction surface of the shell advances these shoes ahead of shoe E, the shoe C advancing more rapidly than shoe D. A limited radial expansion of the shell during the above operation is effective, upon reduction of pressure on the wedge, to initiate release of the shoes.

The antibiotic myxin, and other 1-hydroxy-6- alkoxy-phenazine 5,10-dioxides in which the alkoxy group has 1 to 7 carbon atoms, are prepared by reacting a mono-alkali metal salt of 1,6-dihydroxyphenazine 5,10-dioxide iodinin with an alkylating agent in an aprotic polar organic solvent for the salt and recovering the 6- alkoxy compound. The preferred solvent is hexamethylphosphoric triamide, or dimethylformamide or dimethylsulphoxide may be used. The alkali metal salt (e.g. Na or K) may be prepared in situ in the aprotic solvent by reacting iodinin with an equimolar amount of alkali metal alkoxide therein. Alternatively it is prepared by treating iodinin with an excess of aqueous alkali metal hydroxide, filtering off the required salt and drying it. Alkylating agents may be dialkyl sulphates, alkyl iodides, or alkyl tosylates. The 6-alkoxy compound is recovered from the aprotic solvent by addition of ice-water or a non-solvent such as chloroform and is purified e.g. by chromatography on silica gel or alumina.  1-Hydroxy-6-(3-methylbutoxy)-phenazine 5,10- dioxide is prepared by alkylating the potassium salt of iodinin with 1-bromo-3-methylbutane in hexamethylphosphoric triamide. Reference has been directed by the Comptroller to Specification 1,177,697.

June 2, 1933, No. 15999. [Classes 110 (iii) and 122 (iv)] In turbo-generators, particularly of small size, a steam valve is arranged with a sliding stem having a non-tight fit, and the steam leaking along the stem is collected and led to the interior of the packing of a shaft bearing in order to prevent leakage of air into the turbine. Fig. 2 shows the application to an emergency stop-valve r which is normally held open against the action of a spring 1 by an arm 2 of a bell-crank lever. Leakage steam collects in a channel t<1> and is led by a pipe w to the turbine shaft packing. When, at excess speed, the bell-crank lever is tripped by the out-of-balance governor ring 5, it first knocks down the valve stem to cause the valve to become unstuck, and then permits the spring 1 to close the valve. The regulating valve a, Fig. 1, is arranged in a plane at right angles to that of the emergency valve, and is under the control of a governor n acting through a three-armed lever k. The arm j may have an adjustable head for pressing on the valve stem, or it may act positively in both directions. The stem of the regulator valve may be made a non-tight fit, the leakage steam being used in the shaft packing.
