Title: An improved method of and apparatus for rolling profiles having re-entrant angles
IPC: B21B41/06
Filed: 1951-11-29
Abstract: 701,185. Rolling profiled bars. OESTERREICHISCH-ALPINE MONTANGES. Nov. 29, 1951 [Nov. 30, 1950], No. 28041/51. Class 83 (4) In a method of rolling profile bars having reentrant angles, such as angle bars, U-, I- and T-bars, the metal being rolled is guided from one roll pass to the next, in reversmg channels and twisted through 180 degrees while being so guided. As applied to the rolling of small section angle iron, metal enters a two-high roll stand 3 from a roughing mill through a channel 1 and intake funnel 2, and on emerging is stripped from the roll by a chisel 4 which initiates twisting, and enters a reversing channel 5. An inclined surface 7 of the channel assists twisting, which continues as the metal moves on, so that on reaching the intake funnel 8 of the second roll stand 9 the bar has been twisted through 180 degrees. Reversing channels 13 &c. guide the bar to succeeding roll stands 10 &c., whose intake funnels 16 ... 18 have a section corresponding to that of the preceding roll pass so that the bar is accurately guided into the rolls, preliminary funnels 19 ... 21 damping oscillations in the entering bar. Cover plates 28, 29 allow the bar to emerge from the reversing channel in the form of a loop or introduction of the bar into each succeeding roll pass. From the last stand 12 the profile passes to a cooling bed through a channel 22. Figs. 5 ... 9 (not shown) indicate the shapes of the roll passes rolling proceeding according to the known fold-up system.

Title: Improvements in or relating to concrete mixers fitted with weighing devices
IPC: B28C7/04
Filed: 1930-09-23
Abstract: 354,598. Weighing-apparatus fitted to concrete mixers. SMITH CO., T. L., 1125, 32nd Street, Milwaukee, Wisconsin, U.S.A. Sept. 23, 1930, No. 28471. Convention date, April 7. [Class 143.] A concrete-mixing machine of the type embodying a pivoted charging skip provided with means for raising the same, comprises weighing scales for the skip, a support arranged to receive the weight of the skip and its contents preliminary to weighing thereof, means to remove the weight of the skip and its contents from the support to the scales, and means operable by the skip-raising means to actuate the support to render the same operative to carry the skip and its contents after a weighing operation is completed. As shown, the frame 1 carries brackets 3 in which the pivotal end 4 of the charging skip 6 is journalled so that the skip may be elevated by cables 7 to discharge into the mixing drum 2 in usual manner. The skip whilst being loaded with the aggregates is supported by its pivots 4 and by a cradle 16 suspended by links 15 from bell-crank levers 14. After the addition of each aggregate the skip may be lowered on to a weighing machine platform 20, by turning a hand-lever 32 connected to the cradle 16 by linkage 28, 24. The platform is provided with journal blocks 21 and brackets 22 to support the skip accurately on the platform and to tilt the pivots of the skip from their bearings prior to the weighing operation. The hoisting cable 7 passes over a pulley 27 carried by a lever 25 which is rocked by the movement of the hand-lever 32 so as to slacken the cable. The hand-lever is retained at the end of its movement, by a catch 35. After the weighing operation, the skip is elevated by the cable and a projection 39 on the skip displaces a trip 37 connected to the catch 35 thereby releasing the handle 32 which then returns to its initial position together with the cradle 16 under the influence of a counterweight 40. The frame carrying the skip is provided with hooks 13 so that the frame and skip may readily be attached to, or detached from, the brackets 3 of the mixer frame.

Abstract: 834,343. Oil gases. ESSO RESEARCH & ENGINEERING CO. Sept. 10, 1957 [Oct. 10, 1956], No. 28510/57. Class 55 (2). In a process for producing gases having a calorific value of 450-550 B.Th.U. and containing carbon monoxide and hydrogen from a hydrocarbon oil, there is maintained in a reaction zone 1 a bed of particulate solids including gasifiable material, e.g. coke, at a temperature of 1500-1800 F. and fluidized by steam flowing upwardly therethrough to produce gases which are withdrawn at a velocity above 25 ft./sec with entrained solids through line 4, an hydrocarbon oil being injected through line 2 into the withdrawn gases and solids and the mixture passed to a cyclone separator 6 where the entrained solids are separated, the gaseous products being passed through a wash-box 13 and a washer 15. Solids from the separator 6 are in part returned to zone 1 by line 7 and in part pass by line 8 to a transfer line burner 27 where they are heated by partial combustion to a temperature of 1500-1800 F. before being returned to zone 1 by line 30 to maintain the reaction temperature therein. A heavy tar slurry containing solids is obtained in a separator 18 from the wash-box 13 and is in part returned to the reaction zone 1 by line 23 and in part burned in a burner 31 auxiliary to the transfer line burner 27. A lighter tar is obtained in a separator 25 from the washer 15 and this may be recycled as hydrocarbon oil feed or supplied to the auxiliary burner 31. The particulate solids in the reaction zone 1 may comprise sand, metal, ceramic particles or spent catalyst particles such as nickel, cobalt and molybdenum, e.g. nickel supported on a diatomaceous earth, or a mixture of barium and magnesium oxides. Other catalyst such as lime, partially hydrated lime, dolomite, hydroxides, carbonates and bicarbonates of potassium and sodium, either in powder form or in solution, may be added to the reaction zone either together with the hydrocarbon oil feed or separately. The length of the line 4 is such that the residence time of the injected oil in contact with the gases and entrained solids is less than 0.7 and preferably less than 0.4 second.
