Patent GB-419787-A (GB)
Title: Sulphur condenser
IPC: C01B17/02
Filed: 1934-02-24
Abstract: <PICT:0419787/III/1> Sulphur is condensed from gases containing sulphur vapour, such as are produced by the reduction of sulphur dioxide by carbon, by rapid cooling to 114 to 150 DEG  C. and by bubbling the sulphur-bearing gases through molten sulphur maintained at its lower fluid temperature range.  Such conditions are produced by surrounding the condensing chamber with a liquid having a boiling point lying between the desired limits, e.g. chlorbenzene or water under a pressure of from 10 to 30 pounds per square inch.  Prior to condensation, the gases are washed with molten sulphur at a temperature of 250 to 450 DEG  C. to remove tar vapours and other impurities.  As shown, gases carrying sulphur vapour enter an insulated steel chamber 26 by a pipe 23, the chamber being filled with packing material 22 down which molten sulphur passes. Alternatively, the entering gases make contact with molten sulphur 25 maintained at 350 to 450 DEG  C. so that the gases carry up sulphur vapours which condense on the packing and return to the reservoir. Conditions are so arranged that as far as possible the amount of sulphur vapour leaving by pipe 24 is the same as that entering the sulphur washer, but part of the sulphur is removed and replaced from time to time as contamination increases.  From the washer the gases pass to the condenser consisting of a steel shell 9 having a sloping base.  Projecting from the top and base are hollow partitions 15, 16 serving to divide the shell into compartments, the partitions 15 being provided with rings 15<1> so that the gases are forced to pass through the molten sulphur entrapped thereby.  Flanges 18 are provided on the partitions 15 to catch any large globules of sulphur. Tubes 17 are provided to connect neighbouring compartments. Surrounding the casing 9 is a second casing 14, the space between the two containing the heat dissipating liquid and communicating with the hollow partitions. A pipe 19 is provided for the entrance of the liquid and a pipe 20 for the egress of the vapours.  Molten sulphur leaves by a pipe 13 and the gases by a pipe 12.  Specification 419,788 is referred to.

Title: Improvements in or relating to the production of chlorinated trimethyl acetonitriles
Filed: 1946-03-01
Abstract: Chlorinated derivatives of trimethyl-acetonitrile of the general formula <FORM:0608806/IV(b)/1> where X is an integer from 1 to 3 and Y and Z are integers from 0 to 3, are prepared by reacting trimethyl-acetonitrile and chlorine at a temperature of at least 70 DEG  C., but preferably between 70 DEG  and 165 DEG  C., if desired in the presence of actinic radiation.  By using sufficient chlorine, all the hydrogen atoms of trimethylacetonitrile may be replaced with chlorine.  In examples: (1) chlorine and trimethyl-acetonitrile are reacted in equimolecular proportions in the presence of actinic light, and the products fractionated to yield monochloro-trimethylacetonitrile and minor quantities of di- and trichloro-acetonitrile; (2) similarly, 2 mols. of chlorine and 1 mol. of trimethyl-acetonitrile are reacted to yield two isomeric dichlorotrimethyl-acetonitriles and minor quantities of monochloro-trimethyl-acetonitrile and higher boiling material, mainly trichloro-trimethylacetonitrile; (3) similarly, using greater quantities of chlorine, tetrachloro and pentachlorotrimethyl acetonitrile isomers are obtained. Bis-(cyano-methylpropyl) sulphide is prepared by treating monochloro-trimethyl-acetonitrile with alcoholic sodium sulphide.  Sodium hydroxy-trimethyl-acetate is prepared by treating monochloro-trimethyl-acetonitrile with aqueous caustic soda. Polychloro-trimethyl-acetonitriles may be treated similarly while acid hydrolysis yields polychloro-trimethyl acetic acids. Specification 583,607 is referred to.

Filed: 1952-03-18
Abstract: 706,885. Discharge apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 18, 1952 [March 21, 1951], No. 6962/52. Class 39(1) A step in the manufacture of a glass envelope 2, Fig. 1, consists in providing a portion 11 of accurately dimensioned internal diameter, so that when for example the envelope is part of an electric discharge tube, the said portion may be engaged directly by a non-resilient centring member 1 of the electrode assembly. Initially, the envelope is slightly too large, as in Fig. 2. A gauge 5, having a number of segments adjustable radially, is inserted, and expanded by pushing upwards a central rod 8 with conical end 9; rings 6 and 7 constrain the expansion to the correct diameter. The envelope is then evacuated, and the portion 11 heated, the air pressure forcing the glass inwards around the gauge, so that the correct internal diameter is obtained. To remove the gauge, the rod 8 is lowered, and the gauge segments contracted, either mechanically or by inherent resilience in the lower parts 4.
