Abstract: 364,483. Bag fastenings. NAHAS, M., 29, Boulevard de Magenta, Paris. May 8, 1931, No. 13649. Convention date, Jan. 17. [Class 44.] In a fastening of the kind described in Specification 364,482 the sliding rings 10, 11 are retained in locking position by one or more internal springs 14, co-operating with internal projections in the rings, the ends 12 being of curved form so that the projections 18 in ring 10 may pass thereunder, raising the springs, in either direction, sufficient resistance being offered to retain the ring against accidental displacement. The ends 13 have flat ends and straight portions 17, and snap behind the projections 15 in ring 11 to retain it positively against release movement. Release is effected by moving ring 10 into contact with ring 11, in which position the projections 18 raise the ends 13 clear of the projections 15 and the two rings can then be moved simultaneously to the central releasing position. The projections 18 may be integral with ring 10 or may be on a separate key member 22, Fig. 6, inserted in an aperture 19 in ring 10 and retained by projections 21 engaging in notches 26. The spring ends and the corresponding projections 15, 18 may be of different depths, so that the arrangement is non-symmetrical, and the releasing device may be made inoperative by removing piece 22 and re-inserting it the other way round. Alternatively, it.may be removed and replaced by a member 30, Fig. 7, without projections, which may also serve to prevent movement of ring 10.

Patent GB-467048-A (GB)
Title: Improvements in the treatment of hydrocarbons of low boiling point
IPC: C10G21/10
Filed: 1936-05-14
Abstract: In a process for obtaining fractions rich in aromatic and unsaturated hydrocarbons from benzine and similar light oils, the oil is extracted with sulphur dioxide at a temperature below --18 DEG  C. The lower the boiling range of the benzine, and the higher the content of aromatic hydrocarbons, the lower is the extraction temperature used.  Example: a cracked benzine of boiling range 90 to 140 DEG  C. is treated at --30 DEG  C. with liquid sulphur dioxide in counter-current.  The extract phase after separation and removal of sulphur dioxide contained 61 per cent of aromatic and unsaturated compounds.  With an extraction temperature of --50 DEG  C., the extract contained 80 per cent of these constituents.  The benzine may be first separated into lighter and heavier fractions, the heavy fraction extracted and the extract combined with the light fraction to form a motor fuel.  Extraction may first be effected at --70 to --10 DEG  C., and the extract layer then cooled to --45 to --55 DEG C. to form the desired extract layer.
