Title: An improved manufacture of cyclo-alkadienes
Filed: 1948-04-29
Abstract: In the recovery of cyclo-alkadienes from cracked petroleum naphthas, depolymerization is effected by heating a topped aromatic fraction in liquid phase, and the monomer formed is rapidly stripped by injection of hot vapours.  Fractionation of the cracked naphtha, from which condensed water and uncondensed gases have been removed, may be effected with steam to remove C4 up to 90 per cent C8 hydrocarbons, using a bottom temperature below 300 DEG  F. to avoid depolymerization.  The withdrawn bottoms is generally at about 250-275 DEG  F., and is heated to 330-350 DEG  F. and passed by line 22 to the first zone 24 of heater 23 where it accumulates until it attains the height of overflow 25 leading to the second stage 26 where heating to 350-380 DEG  F. is effected by circulation through reboilers 27, 28. Vapours containing monomers rise through line 31 and are bubbled through the liquid in the first stage from a perforated distributer 35 stripping monomers formed in the said stage. Heating is effected for 4-8 hours, the vapours being taken off by line 32, cooled rapidly, and fractionated, bottoms being recycled to the first zone 24.  Steam or other inert gas may alternatively be used for stripping the monomer vapours or a multi-stage, counter-current stripping process may be employed. <PICT:0636308/III/1>ALSO:<PICT:0636308/IV (b)/1> In the recovery of cyclo-alkadienes from cracked petroleum naphthas as described in the parent Specification, depolymerization is effected by heating the topped aromatic fraction in liquid phase, and the monomer formed is rapidly stripped by injection of hot vapours.

Title: Planetary rolling mills
IPC: B21B13/20
Filed: 1971-04-28
Abstract: 1342634 Rolling mills T SENDZIMIR 28 April 1971 11828/71 Heading B3M A planetary strip rolling mill includes working rolls carried in cages and supported by backing rolls, the cages and backing rolls being so geared together that each working roll contacts the same angular portion of its backing roll during its working stroke. By suitably profiling the angular portion, the working roll deviates from a true circular path and reduces the torque demand of its drive during the last, part of its working stroke. Each backing roll 1, Fig. 3, has a non-circular periphery which causes each working roll 2 to move in a path having a straight end section C-D. The diameters of the work and backing rolls and the number of work rolls are so chosen that each work roll contacts the same portion of the backing roll in each cycle. The rotation of the work and backing rolls is synchronized by gears 35 and 36 (Fig. 2) connected to the backing rolls and to the cages. The torque demand of the mill drive can additionally be controlled by regulating the driving speeds of the backing rolls and cages (Fig. 5). A driving motor 19 is coupled to a planetary gear set whose planet carrier 25 is drivingly connected to the mill stand through a pinion stand 20 and flexible pinions 9, 9<SP>1</SP>. The annulus 26 of the set is given a cyclical oscillating movement under the control of a cam (Fig. 6, not shown) which rotates in synchronism with the cages. If only two work rolls are provided for each backing roll, it is possible to stop movement of the cages and operate the mill as a four-high stand. The two sets of work rolls can then be given different surface finishes, so that by rotating each cage through 180 degrees a different rolling schedule may be used. The ratios of the backing roll to working roll diameters may be e.g. 1 : 1, 2 : 1, or 4 : 1, and the corresponding ratios of driving speeds of the backing rolls to cages 4 : 1, 3 : 1, and 2À5 : 1. Arrangements are described in which 2, 3, 4 or 6 working rolls are provided for each backing roll.
