Patent GB-486980-A (GB)
Title: Improvements in and apparatus for the separation of gas mixtures into their components
IPC: B01D5/00
Filed: 1937-02-08
Abstract: <PICT:0486980/III/1> In separating gaseous mixtures by partial liquefaction followed by washing of the uncondensed gases with a solvent, the constituents obtained on regeneration of the solvent are returned to the liquefaction stage.  The liquefied faction may be partly re-evaporated and the vapour passed on with the uncondensed gases. The washing with solvent may be effected firstly in co-current and then in countercurrent.  The Figure shows the application of the process to the separation of a mixture of methane, ethylene, ethane, propylene, and butylene.  This is compressed at b to 20 atmospheres and cooled in d to 27 DEG  C.  About 6 per cent of the condensate is evaporated again in e.  The gases are mixed with washing oil from the pipe h and passed through a cooler i into a tower k to which washing oil is supplied by pipe l.  The solvent is withdrawn and treated in a regenerated o and the evolved gas is returned by pipe c to the system either before or after the compressor.  The condensate withdrawn at g consists almost entirely of the propylene and butylene and the other constituents of the mixture issuing at n are practically free from these substances.

Abstract: 181,676. Western Electric Co., Ltd., (Assignees of Casper, W. L.). June 11, 1921, [Convention date]. Transformers.-In order to reduce the capacity effect between the primary and secondary coils of a high-frequency transformer employed in association with an amplifying-tube in a telephonic repeater-circuit adjacent layers of the primary and secondary coils are so arranged as to have an effective ground potential. The outside layer of the split secondary 6, 7 is connected through a terminal 12 to the grid 19 of the tube 20, whilst the inside layer, that adjacent to the split primary 4, 5, is connected through a terminal 15 to the grounded cathode 21 of the tube. The resultant inter-coil capacities are shown diagrammatically at A and B, Fig. 2. Owing tn its symmetrical position, the conductor 16, joining the two portions 4, 5 of the primary, is maintained at an effective ground potential, so that the points 10 and 15 are equipotential and the capacity B has no existence in fact. As the impedance of the primary coil 4 is very small relatively to that of the secondary coil 6 the capacity effect A is practically the same as if it existed between the points 13 and 9, the latter being at effective ground potential. Further, owing to the ground connection at 22, the capacity A is in effect shunted around the coil 7. The single effective capacity A is therefore practically negligible, and the circuit is capable of high-quality speech transmission.

Abstract: 469,967. Loud - handling machines; winches. YALE & TOWNE MANUFACTURING CO. Feb. 17, 1936, No. 4756. Convention date, June 22, 1935. [Classes 78 (iii) and 78 (v)] Lifting and pulling mechanism, for controlling the operation of a work or lifting shaft, is provided with a load-holding ratchet wheel loose on the shaft but clamped frictionally thereto by the axial movement of a reversibly-operable ratchet driving-wheel mounted on a threaded portion of the shaft, the ratchet driving wheel being operated by a handle carrying a reversible pawl. In the illustrated form the handle 50, by 'withdrawing and reversing the pawl 52 through the medium of the sliding bolt 57, can be made to drive the ratchet wheel 35 in either direction. When the wheel 35 is moved clockwise to hoist the load, the screw 34 causes it to move axially and jam the retaining ratchet wheel 32 together with the friction disc 33 against the member 30 fixed on the shaft 29, thus driving the pinion 27 which gears with the pinion 42 on the shaft of the load chain wheel 42a. When the handle is released, the load is sustained by a pawl 45 engaging the ratchet wheel 32. To permit gravity lowering, or paying out under the strain of the load, the pawl 52 is reversed and the handle 50 rotated sufficiently to ease the pressure between the members 30 and 33. Rapid adjustment of the unloaded chain is obtained by rotating the ratchet wheel 35 by means of the hand wheel 36. The appliance is anchored or supported by a swivelling hook 11 and may be used by attaching a load hook 15, Fig. 3 to the chain, or the hook 15 might be attached to a strap supported under the lug 20 and on the side lugs 21 to form a loop in the chain, a third load hook in this case being carried by a sprocket running in the loop of the chain.
