Title: Improvements relating to steam generators
IPC: F22B1/14
Filed: 1930-06-16
Abstract: 359,400. Indirectly heated steam boilers. BAUMANN, K., Northwoodhouse, Barnfield, Urmston, Lancashire. June 16, 1930, No. 18425. [Class 123 (ii).] Steam boilers comprise furnace-heated watertubes discharging into one or more drums, a number of evaporators in one or more of which steam is directly introduced into the water space, and the rest, which may include the boiler drum or drums, are of surface-heating type and a number of superheaters between each successive pair of which in the steam circuit are disposed the desuperheating elements of the evaporators. Water-tubes 1, 1a, 1b lining the walls of a combustion chamber 20 discharge into a steam drum 2 from which steam passes to a superheater 7 at the rear of a chamber 21. The steam then passes successively through the heating element 8 of an evaporator 4 and a superheater 9 whence it is discharged into the water in a direct contact evaporator 5. Steam generated in this evaporator passes through a superheater 11, the heating element 12 of an evaporator 6 and a superheater 13 to the outlet 22. Steam generated in the indirect contact evaporators 4, 6 unites with steam from the drum 2 on its wav to the first superheater. The steam flow in all the superheaters except the last is counter to that of the furnace gases. Modified boiler constructions similar to embodiments shown in Specifications 340,295, 342,361, and 343,594 are described.

Title: Improvements in or relating to the alkylation of benzene
IPC: C07C2/68
Filed: 1942-12-30
Abstract: <PICT:0564059/IV/1> Benzene is alkylated by passing a feed containing benzene and olefins into a reaction zone containing a catalyst of the Friedel Crafts' type, fresh catalyst being introduced, and reaction products, unreacted constituents, and catalyst overflowing into a settling zone wherein unreacted vaporized constituents are separated, scrubbed with polyalkyl derivatives of benzene and the olefins to remove benzene, and the solution of benzene in said polyalkyl derivatives separated and recycled to the reaction zone. The feed may be benzene and an ethylenic gas containing ethane which react in the presence of aluminium chloride at about 160 DEG  F. to yield ethyl benzene.  A feed containing benzene and olefins together if desired with hydrogen chloride, is led by line 2 to reaction tower 1 containing aluminium chloride.  Reaction products and catalyst flow by conduit 5 to settler 6 whence catalyst can be recycled by lines 8, 9, gases leave by line 7, and liquid products pass through receiver 11 to still 13 where unreacted aromatics are separated and may be recycled by line 19, while alkylated products pass to still 16 where the desired product, e.g. monoethyl benzene, is removed by line 17, and heavier constituents, e.g. polyethyl benzenes, leave by line 18 for recycling or discharge.  The gases leaving by line 7 contain benzene vapours which are washed out in packed tower 25 by polyethyl benzenes introduced by line 21, the solution then being recycled by lines 23, 19 to reactor 1.  The content of absorbed benzene should not exceed about 10 per cent.

Title: Improved method of making the return bends of steam superheater elements and like pipe structures
IPC: B21C37/28
Filed: 1930-06-17
Abstract: 355,414. Making steam generators and pipe bends. SUPERHEATER CO., Ltd., Bush House, Aldwych, London, and WHITTLE, R. W., of Superheater Co., Trafford Park, near Manchester. June 17, 1930, No. 18514. [Classes 83 (ii) and 83 (iv).] Pipe-end closing; forging dies; welding.-In uniting the ends of two or more parallel pipes to form return bends for steam superheaters and the like, particularly smoke tube superheaters, the pipes with their end portions heated are first placed in a die and the adjacent walls are slit longitudinally and the slit portions turned outwardly and welded together by a punch, whereupon the united end portion is reheated and subjected in a second die to the action of a second punch so as to stave up or thicken the wall of the union and to consolidate the weld. The pipes are held between the upper and lower halves of a die having semicylindrical recesses separated by a partition 5 and a wide recess extending from the end of the partition to the opposite end of the die. The slitting and welding is effected by a punch having a slightly tapered waist 11 and tapered legs 12, as described in Specification 6304/15, [Class 83 (ii), Metal articles &c.]. This punch may also have a shoulder 10 to stave up or thicken slightly the wall of the waist portion of the forging, and to obtain a forging in which the recesses 14, which are formed by the drag of the punch on the metal, are only slight. After reheating the united end portion, the forging is placed in a die which may be of the same form and dimensions as in the previous case and the weld is consolidated and the wall of the waist portion staved up or thickened by a second punch having a forging shoulder 10a a lesser distance from the crotch 16 of the die than in the first case, and the waist portion 11a of smaller cross section than that of the first punch. In modifications the cross section of the punch may be the same as in the first case, the recess in the die being of larger dimensions, or the punch may be of smaller cross section and the die recess of larger dimensions. A return bend may then be formed after reheating by bring- ing the end portion 13 to circular shape, closing the end, cutting off the pip and flattening the bend as described in Specification 120,042, [Class 83 (ii), Metal articles &c.]. For certain structures the end may be left open after swaging down to cylindrical form. Three parallel pipes with axes at the angles of a triangle may be similarly formed with a threepronged punch and an appropriately profiled die or dies.

Title: Improvements in or relating to organosilicon compounds
Inventor: SHAW ROBERT ALFRED
IPC: C07F7/08
Filed: 1962-05-17
Abstract: Organo-silicon compounds are converted into other organo-silicon compounds, generally of higher molecular weight, by subjecting their vapour to an electric discharge in a discharge cell in which the total gas pressure can be controlled and is maintained up to 20 cm. Hg greater than the vapour pressure of the starting material. Specified starting materials are alkyl and aryl silanes and siloxanes.  The vapour of the organo-silicon starting material is introduced into a suitable electrical-discharge apparatus from which air has been removed, which is immersed in an electrolyte bath, and is subjected to a "silent" or corona electrical discharge of between 10 and 40 kv. for a discharge path 0.5 cm. long.  Liquid products are drained from the apparatus and solid products are washed out with a solvent.  The lower-boiling liquid products may be separated into components by fractionation followed, if necessary, by gas-liquid chromatography.  The examples describe the variation of percent conversion to liquid products of (1)-(7) hexamethyldisiloxane and (8)-(9) tetramethylsilane with the variation of pressure, temperature, time and discharge voltage.  Typical compounds identified in the products from Examples 1-7 are (CH3)3SiOSI(CH3)2C2H5; (CH3)3SiOSi(CH3)2-O-Si(CH3)2 -Si(CH3)3;(CH3)3SiO-Si(CH3)2 -O-Si(CH3)2 -O-Si(CH3)2Si(CH3)3; and from Ex-, ample 8 and 9 are (CH3)3SiC2H5; (CH3)3Si-Si (CH3)3 and (CH3)3Si-CH2 -CH2-CH2Si(CH3)3.  The high-boiling components are separated into 4 boiling ranges by molecular distillation.

Patent GB-192391-A (GB)
Abstract: 192,391. Bonnat, M. Jan. 25, 1922, [Convention date]. Driving machines.-The breakage of wire &c. in wire-drawing machines &c. is indicated through the action of loose members, such as brass balls e, Fig. 1, situated in passages d in a member c rotated by the wire and normally projected by centrifugal force outwards from an electrically-conductive axle a, b. When the wire breaks, one or more of the balls fall by gravity inwards on to the conductive axle whereby an electric circuit is closed, and a warning signal is actuated, or the machine is stopped, or both. In the example shown in Figs. 1 and 3, a creel warping spindle is made in two parts a, b secured together by a sleeve c of insulating material provided with channels for the balls e closed by plugs or by a jacket b. The unwinding of the thread from the spool or cop on the part a rotates the spindle, but when this stops rotating one or more balls fall into position to close circuit through the parts a, b. The conductive axle may be vertical and be formed with inclined passages for the balls. A modification is described wherein a fixed spindle is used whereon a cop or spool is rotated. The actuation of the signal or stoppage of the machine may be effected by the rupture of an electric circuit, by means of a relay.
