Title: Removal of sulfur contaminants from hydrocarbon stream
IPC: C07C7/171
Filed: 1958-06-23
Abstract: Hydrocarbon streams containing C4-C6 normal alkenes and isoalkenes and contaminated with sulphur are purified by contacting with 60-70 weight per cent sulphuric acid at 50-120 DEG F. and 15-125 p.s.i.g. to dissolve isoalkenes and convert sulphur contaminants to higher boiling compounds and distilling the normal alkene containing product free of isoalkene to separate it from the higher boiling sulphur contaminants.  The process is particularly useful to obtain n-butylenes free of isobutylene and sulphur contaminants for conversion to secondary butyl alcohol by subsequently dissolving in sulphuric acid and hydrolysing. Suitable starting materials are C4 olefine refinery streams obtained by thermal, catalytic or steam cracking of hydrocarbon oils and containing 40-60% butane, 7-20% isobutylene and 20-42% n-butylenes with small amounts of C3 and C5 hydrocarbons and contaminated with sulphur and sulphur compounds. Such a stream may be first washed with 12-17 DEG  B<\>ae aqueous caustic soda for a preliminary sulphur removal.  The amount of acid used may be such that the volume ratio of hydrocarbon to acid is from 5 to 20:1.  The n-butylene obtained may be dissolved in 70-80 weight per cent sulphuric acid using 1-10 volumes of hydrocarbon per volume of acid at 80-135 DEG F. and 15-125 p.s.i.g. The extract formed is contacted with water and/or steam at 0-100 p.s.i.g. and 200-300 DEG F. to obtain secondary butyl alcohol.

Abstract: 757,717. Stuffing-box substitutes. BRITISH THOMSON-HOUSTON CO., Ltd. July 21, 1954 [July 21, 1953], No. 20220/53. Class 122(5) A sealing gland for a rotating shaft 1 comprises a gland housing 14 and an annular sealing member arranged with its end faces respectively in rubbing sealing contact with a member 2 secured to the shaft and a non-rotatable member 12 and carried by the cage 6 of a thrust bearing interposed between the shafts and the gland housing so that the sealing member rotates at less than the shaft speed. The shaft 1 extends through a casing (not shown) and is packed by two seals housed in the housing 14 and spaced by a chamber supplied through an inlet 19 with oil at a pressure exceeding that in the casing. The seal remote from the casing comprises a pair of carbon rings 7 carried on opposite sides of the cage 6 of a ball thrust bearing and resiliently urged into contact with both a steel collar 2 attached to the shaft and a non-rotating metal ring 12 by a helical spring 13 located between the ring 12 and the gland housing 14 and arranged so that the torque due to friction at the sealing faces tends to increase its external diameter and cause it to grip both the ring and the housing to thereby prevent the ring, which is sealed to the housing by a rubber ring 15, from rotating. The bearing races 4 and 8 are respectively secured to the collar 2 and a carrier ring 9 urged into contact with the thrust balls 5 by a number of springs 10 and prevented from rotating by a locating screw 11 engaging an axial slot in the ring 9. The cage and carbon rings rotate due to friction at a speed, preferably half the shaft speed, dependent on the strength of the springs 10. Leakage oil is drained away at 21. The second seal comprises a carbon ring 16 pressed into contact with the shaft by a garter spring 18.

Title: Improvements in slab tongs
IPC: B66C1/42
Filed: 1964-05-22
Abstract: 1,057,778. Hydraulically opened slab tongs. SOC. FIVES LILLE-CAIL. May 22, 1964 [June 12, 1963], No. 21256/64. Heading B8H A pair of slab-tongs 10, 12, which are opened by an hydraulic ram 22, have a hydropneumatic accumulator communicating with the chamber above the piston in the ram 22 which serves to absorb sudden shocks in the hydraulic system which occur when the tongs are in use. A safety valve prevents sufficient hydraulic pressure being developed to open the tongs when a load is being lifted. A pump and electric motor for the hydraulic fluid are accommodated within a frame 20 or on a grab of a crane from which the tongs are suspended. To open the grab fluid is supplied to the ram 22 through a three-position switch which may be operated by solenoids or manually. When the tongs are open the three-position valve is returned to its central position in which the chamber above the piston and the accumulator are isolated from the rest of the system. The tongs are thus held open, and shocks are absorbed by the accumulator which may be filled with compressed nitrogen. The accumulator may comprise an annular body within the piston chamber and form a seal between the piston-rod and the ram body.
