Title: Continuous process for the dehydration of organic liquids other than ethyl alcohol
IPC: B01D3/36
Filed: 1924-01-22
Abstract: 215,716. Soc. Ricard, Allenet, et Cie. May 9, 1923, [Convention date]. Alcoholic liquids, distilling; glycerine, concentrating. - Organic liquids are dehydrated by distilling in presence of a liquid which yields a vaporous mixture containing water vapour at a lower temperature than the boiling points of the constituents, forming, on condensation, a distillate which separates into two layers, the layer containing the greater proportion of the added liquid being returned to the distilling- apparatus. Suitable liquids are benzene, toluene, xylene, solvent naphtha, esters, hydrocarbons, and chlorinated derivatives such as trichlorethylene, and nitro compounds, such as nitrobenzene, nitrocyclohexane, and nitromethane. In dehydrating glycerine, toluene is placed on the plates of a column A heated by steam coils S', S<2>, S<3> to obtain a maximum temperature of 120‹ C., and glycerine is supplied by a pipe a. Vapours containing toluene and water pass at about 83.7‹ C. to a condenser C. The condensate separates into two layers in a vessel D. The lower layer of water is discharged through a pipe f and the upper layer of toluene is returned to the column by a pipe n. Dehydrated glycerine is withdrawn from the base of the column A through a cooler H. In dehydrating propyl alcohol by distilling in presence of trichlorethylene, both the upper and lower layers in the separating vessel D contain substantial proportions of propyl alcohol. The lower layer containing mainly trichlorethylene is returned to the column A, and the upper layer is passed in succession through two small distilling columns the first of which yields vapours mainly of trichlorethylene which are passed into the pipe b, and the second yields, as vapours, propyl alcohol which is passed to the column A, and, as residual liquid, water which is discharged from the base of the column. Specifications 159,880, 206,747, 213,985 and 214,581 are referred to.

The housing 4 in the form of a circularly sectioned hollow cup is fixed in the wall of waveguide 1 and a centrally bored and tapped circular nut 6 retains in said housing a nylon bush 5 with a hole 5a therein. The adjustment screw 3 is threaded through nut 6 and bush 5 cutting a thread in the latter and extends through hole 2 in the housing into the waveguide 1. A cover cap 7 may be screwed on to the housing. In a modification (not shown) the screw is threaded through the hole 2 in the base of the cup and not through the nut 6, and the bush 5 is slightly smaller than its recess so that the nut 6 does not quite make contact with it.

Title: Improvements in or relating to sub-aqueous pressure wave sonar systems
Inventor: GLASGOW JOHN ARTHUR

Filed: 1965-01-19
Abstract: 1,125,152. Sonar systems; magnetostrictive transducers. MARCONI CO. Ltd. 3 Dec., 1965 [19 Jan., 1965], No. 2375/65. Headings H4D and H4J. In a sonar system a sub-aqueous region is scanned rapidly in the azimuthal plane by periodically transmitting an extended pulse of pressure waves substantially isotropically and sweeping the direction of maxium received signal strength of a directional receiving transducer array over at least a fraction of the azimuthal plane during the transmission of the pulse. In the embodiment illustrated in Fig. 1 (provisional), a 50kc/s acoustic pulse is transmitted by a cylindrical magneto-strictive transducer 3 for every 8À1 revolutions of a magneto-strictive receiving array 15 about a vertical axis 5, the pulse duration (150ms) being approximately equal to the period of rotation of the array 15. Timebase generators 9 and 11, synchronized with the rotation of the array 15, provide deflection waveforms for a cathode ray tube 14 the beam of which is intensity-modulated by target echo signals received by the array 15, and produce a raster which comprises ten inter-leaved spirals of eight turns each, the start of each spiral corresponding to the initiation of a transmitted acoustic pulse. The use of such a "tenstart" raster enables a target range resolution (in the resulting P.P1 display) equivalent to that given by a raster comprising a single 80-turn spiral to be obtained at one-tenth the receiving array rotation rate that would be required for the single-spiral raster. Target range gating may be provided by gating an echo signal amplifier 16. Transducer construction:-The transmitting transducer (Fig. 2, provisional, not shown) comprises a toroidally-wound stack of annular magneto-strictive laminae (31). The receiving array (Fig. 3, provisional, not shown) comprises a 2 feet row of cores, each core comprising a stack of #-shaped laminae. A winding (153) is wound over the "legs" of the # and the array is polarised by a permanent magnet.
