Title: Automatic braking apparatus for railway wagons
IPC: B61H11/02
Filed: 1929-11-23
Abstract: 340,723. Brakes. DUNSMORE, M. C., 12, Windsor Place, Stirling, and RITCHIE, D. W., Atlas Works, Temple, Glasgow. Nov. 23, 1929, No. 35910. [Class 103 (i).] Applied by backward pressure of tractor ; hand and foot actuation.-In an automatic braking system for railway wagons wherein the brakes are applied when the wagon tends to over-run the locomotive or preceding wagon by inward movement of a central buffer-drawbar, the braking effort is unable to exceed a pre-determined maximum and any tractive effort applied to the drawbar is not transmitted to the brake mechanism. The bufferdrawbar 1 is operatively connected to the brakeoctuating lever 5 through a main buffer compression spring 2 acting on a flanged sleeve 8 movably connected to the bar 1 by a cotter 15 and slot 16 and fixed to a rod 7 by a cotter 14. Compression springs 3, 4 operate between the sleeve 8 and a washer 9 secured to the rod 7 by a cotter 12 and slot 13, the washer 9 abutting a collar 10 slidably mounted on the rod 7 and engaged by the bifurcated end of the lever 5. The latter is secured to a transverse shaft 29 connected through levers 30 and links 31 to brake shoes 32 held by links 34 pivoted to the frame 19. A light compression spring 28 is interposed between the collar 10 and a boss 26 on a frame-member 27 and a similar spring 6 between the flange 17 on the sleeve 8 and a fixed bracket 21. In operation, tractive effort applied to the bar 1 compresses the spring 2 between the flange 17 and a plate 18 and the rod 7 together with the springs 3, 4 and washer 10 moves outwardly with the bar 1. The spring 28 causes the collar 10 to follow the washer 9 and increase the brake clearance. When the bar 1 is compressed, the rod 7 is moved inwardly through the medium of the plate 18, the spring 2 and sleeve 8 thus gradually compressing the springs 3, 4 to apply the brakes until a shoulder 50 on the sleeve 8 abuts a shoulder 51 on the boss 24 when further movement of the bar 1 compresses the main spring 2. A manually operable lever 35 is secured to one end of the lever 29 and is movable into any one of three positions, namely an " off " position 36 in which the brake mechanism is rendered inoperative by the bar 1, a running position 37 in which the brakes are free to function automatically, and an " on " position 38 in which the brakes are maintained in the applied position. The lever 35 may be manually operated by screw-actuating means to apply the brakes with great pressure.

Abstract: <PICT:0863802/IV (b)/1> A mixture of C5 and C6 hydrocarbons is isomerised by separating iso-pentane from a fresh feed and recycle feed containing n- and iso-pentanes, passing the bottoms from this step with hexanes to the isomerisation step, which is effected in the presence of a solid isomerisation catalyst, separating from the effluent a fraction containing hexanes and a recycle-fraction containing n- and iso-pentanes and recovering iso-pentane and hexanes as product.  Fresh feed containing C5 and C6 hydrocarbons is passed by line 12, together with recycle from line 108 to fractionator 14 operated at 0-200 p.s.i.g. and 80.320 DEG F. from which iso-pentane product is recovered by line 22. The bottoms are heated and isomerised in the presence of hydrogen in reactor 33, e.g. by the process described in Specifications 863,800 and 863,801.  The effluent is cooled and hydrogen separated and recycled and fed into fractionator 66 from which C4 and lighter products are obtained overhead.  This fractionator may be operated at 100-400 p.s.i.g. and 140-390 DEG F. The bottoms are further fractionated in tower 94 operated at 0-200 p.s.i.g. and 100-350 DEG F. to separate n-and iso-pentanes overhead for recycle by line 108 and hexane bottoms. Hexane product, together with hexanes separated from the feed if desired, may be fractionated to separate iso-hexanes from n-hexane, the former being recovered as product, the latter being combined with bottoms from fractionator 14 for isomerisation.
