Abstract: 633,738. Apparatus for use in connection with the science of sound. WRIGHT, P. June 18, 1947, No. 16047. [Class 146 (ii)]  Apparatus for use in experiments connected with the science of sound comprises a source of vibrations and a sonometer mounted on a common base, through which the vibrations are conducted to the sonometer. A rod 17, Figs. 1 and 4, is clamped centrally to a support 7 by wing-nuts 15 and has a thin aluminium disc 18 which is located in one end of a Kundt's dust tube 12 supported on blocks 6, 8 by means of sheet metal brackets 10 adjustably secured to the blocks by wing nuts 11 and screws passing through vertical and horizontal slots 8b, 10a in the blocks and the brackets respectively. A sonometer wire 21 is stretched between a spring- balance 20 secured to an extension of the block 6 and to a screwed rod 22 passing through an extension of the block 8, whereby the tension of the wire can be adjusted by a wing nut 23. The wire rests on transverse metal strips 24a, 25a secured respectively on fixed and slidable blocks 24, 25, whereby the effective length of the wire is adjustable. The rod 17 may be set in vibration by stroking with a cloth moistened with methylated spirit or by electromagnetic, electrostatic or magnetostriction methods, or a diaphragm supported on the base 5 and having a similar disc 18 may be used instead of the rod and set in vibration by being included in an electronic circuit, or by a piezo oscillator or a Kripp's tube. A paper rider is placed on the wire 21 and the block 25 moved until the rider is thrown off, when the wire is in resonance with the rod. Hence the frequency of the vibrations of the rod is determinable and thence the velocity of sound in the rod. The frequency now being known, the dust tube 12 is utilised in Kundt's experiment to find the wave-length and thereby the velocity of sound in the gas in the tube.

Title: Liquid phase butane isomerization process
IPC: C07C5/27
Filed: 1959-05-12
Abstract: In the liquid phase isomerisation of n-butane at 50-250 DEG F. in the presence of aluminium halide and hydrogen halide, the hydrogen halide is recovered and recycled being mixed with fresh butane feed and subjected to intense scrubbing and fractionation <PICT:0877817/IV (b)/1> in a combined scrubbing-stripping unit to reduce the amount of hydrogen recycled to the isomerisation zone to less than 0.1% by volume based on butane entering the reaction zone.  Butane enters by line 11 and is divided into three streams, one passing by line 11a to the top of tower 14, another after heating passes to the middle of the tower and the third, about 1-5% of the feed, passes to tank 18 by lines 16 and 17 where aluminium chloride is picked up.  The stream in line 17 becomes saturated with aluminium chloride and this is then diluted by butane in line 16 to prevent deposition of the chloride in pipes.  This stream is then joined by butane containing hydrogen chloride from tower 14 and together are passed through reactor 25 which contains aluminium chloride absorbed on bauxite.  Suitable conditions are 100-250 DEG F., 250-500 p.s.i.g. 0.2-2 vol./vol./hr. with 1-10% mol of added hydrogen chloride.  The product is stripped of hydrogen chloride and other gases in stripper 28.  Butane is condensed out from the overhead and returned as reflux.  The gases together with make-up hydrogen chloride are recycled to dissolve in butane feed in line 11 and pass to tower 14.  In the bottom of the tower a reboiler expels dissolved hydrogen, while in the upper part the expelled gasses are contacted with cold butane, about 4% of the feed, to dissolve expelled hydrogen chloride.  Gases leave by line 40.
