Abstract: 703,157. Builders' hoists ;catch gear; end stop gear. BUCKLE, H. Feb. 13, 1951 [Feb. 15, 1950], No. 3908/50. Classes 78 (3) and 78 (5) A winch driven builders' hoist has a ratchet catch device normally held out of operation by the tension in the hoisting rope, and clutch operating means, located in the path of the platform, which serves automatically to disconnect the winch drum from its driving unit at the extreme positions of the platform. A platform 21 has pairs of flanged wheels 22, 23 respectively engaging the front and rear faces of a pair of guide members 18 on a mast 19, the flanges of the wheels being disposed respectively on the outer and inner edges of the guide members to provide lateral stability. The platform is raised by a winch 14 and a cable 28 which passes over pulleys 34, 33 and is anchored at 30 to a pawl 26 pivoted to the platform at 27. Normally this pawl is held away from a ratchet bar 25 by the tension in the cable, but, in the event of the cable breaking or running slack, springs 31 effect engagement of the ratchet and pawl so checking the fall of the platform. The winch is manually controlled by a hand brake (not shown) and a lever 37 which, when in the neutral position shown in Fig. 5, disconnects the drive to the winch, but which, when moved to pivot levers 38, 41 clockwise or anti-clockwise, effects raising or lowering movement of the winch. Should the lever 37 be still in one of its extreme positions when the platform reaches one of its end positions, the lever 37 is automatically returned to its neutral position by one of cables 39, 42 which are actuated by levers 40, 43 pivoted in the path of the platform. The hoist is mounted on retractable wheels 50 and, for transit, the guide mast may be pivoted downwardly about an axis 11 ; to facilitate this, a brace arm 44 is detached from a clamp 46 and is allowed to ride out on its wheel 48 so steadying the mast as it is lowered by cable and drum (not shown). Specification 703, 156, [Group XX'IV], is referred to.

Patent GB-580102-A (GB)
Title: Improvements in or relating to the fractional distillation of hydrocarbons
IPC: C07C7/06
Filed: 1944-03-07
Abstract: Hydrocarbon mixtures containing xylene isomerides with styrene, or with saturated hydrocarbons having boiling points substantially within 10 DEG C. of that of styrene, or with both styrene and such hydrocarbons, are separated by adding ethylene-glycol-monomethyl-ether as an azeotrope former, and subjecting the mixture to fractional distillation.  The azeotrope-former may be washed out of the individual fractions with water, and substantially pure xylenes, styrene, and saturated hydrocarbons obtained.  The distillation may be carried out at barometric pressure or, advantageously, at reduced pressures.  In an example, commercial 2 DEG  xylole was mixed with an equal weight of ethylene-glycolmonomethyl-ether and fractionally distilled in a 30-plate column at barometric pressure.  The first distillates, boiling below 118 DEG C., contained between 40 and 50 per cent. of hydrocarbons which were recovered by washing out the ether with water and, after drying, had specific gravity 0.76 to 0.80.  The fractions distilling between 118.5 DEG  and 119 DEG C. contained the azeotropes formed from the xylenes.  In another example, crude light solvent naphtha was washed with caustic soda solution, dilute sulphuric acid, and water, and was then fractionated batchwise in a 40-plate column, the pressure being reduced in stages so that the distillation was carried out without the charge being heated above 80 DEG C.  The 72 DEG -75 DEG /73.5 m.m. fraction was found to contain over 50 per cent. styrene; it was admixed with two-and-a-half pints of ethylene-glycol-monomethyl-ether and fractionally distilled in the same column at 73 m.m.  The styrene/ether azeotrope was collected between 59.4 DEG  and 60.4 DEG ; it contained 3.6 per cent. of styrene which was recovered by water washing.  Examples are also given in which the azeotrope-former was added in only sufficient quantity to bring over one constituent or constituent group. Specification 536,172 is referred to.
