Patent GB-795670-A (GB)
Title: Improvements in or relating to contacting gases or vapours and liquids
IPC: B01J19/10
Filed: 1955-02-03
Abstract: In processes of the kind in which a vapour or gas is contacted with a liquid wherein the liquid descends through a vessel and the gas or vapour ascends in counter-current flow, sonic or ultrasonic vibrations are imparted to the vapour or gas prior to its entry into the vessel or at the inlet end of the vessel whereby the vapour or gas is vibrated during its contact with the liquid.  The process may be applied to fractional distillation and gas-liquid reactions or liquid catalysed gaseous reactions; absorbing gases in liquids, humidifying gases, and purifying gases by washing with liquids; or drying gases with desiccant liquids.  Referring to Fig. 1 which illustrates a distillation apparatus, the column K is a fractionating column wherein ascending vapours are contacted with descending liquid.  The vapours are produced in the still or reboiler A and pass through the sound-producing <PICT:0795670/III/1> means C which is a conventional siren comprising a stator G and a rotor C each having slots I and H respectively.  The rotor is driven by the shaft E by external means.  The passage of the vapour is interrupted by the siren thereby imparting sonic vibrations.  Vapours leave the siren by the tangential pipe J. Part of the vapour may be recycled by pipe L to the still thereby reinforcing the amplitude of the vibrations, the lengths of the recycle preferably being such that the recycled vapour is in phase with the vibrating means.  Refluxed liquid returns to the still by pipe M.  The column K is of a type to give a large area of interfacial surface with minimum damping of vibrations such as a wetted wall type, of spray chamber pattern.  Refluxed liquid from the condenser O is preferably returned to the column as fine drops, e.g. by passing through a spray.  The vibrating means may alternatively be a siren arranged for axial vapour flow and may be located at the base of the column, in the vapour space of the still or in a branch of the line to the column and operated by compressed gas or steam.  It may also be a whistle operated by compressed gas or steam, or a magneto-strictive device or piezoelectric transducer.

Title: Improvements in or relating to velocity modulated electron tubes
IPC: H01J23/027
Filed: 1961-01-27
Abstract: 909,558. Velocity modulated tubes. CSF. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Jan. 27, 1961 [Feb. 25, 1960], No. 3219/61. Class 39 (1). In a velocity modulated tube, e.g. a klystron or travelling wave tube, the collector comprises a plurality of metal elements 9, Fig. 1, bounding a frustoconical space, whose axis is inclined to the beam axis, means in the collector space for decelerating the electron beam and a magnetic field in the collector space which has decreasing intensities from the smaller to the larger cross-section of the collector so that the electrons move in a helix of increasing radius and impinge on the metal elements 9. The electrostatic field causes reflected and secondary emitted electrons to return off the axis so that they are less likely to re-enter the resonator system. In one form, Fig. 1, there are four separate annular magnetic coils around an array of annular collector flat slanted rings 9 forming the envelope of a cone and closed at the large end by an inclined flat plate 12. The plate 12 is at cathode potential and collector rings are at graded potentials between this potential and the potential of the block 2 housing the four resonators which is at a high positive potential. The magnetic coils have decreasing numbers of turns in the direction of the beam so that the magnetic field decreases in intensity in this direction. If the coils are identical and of successively decreasing currents, the internal surfaces of the collector rings 9 may have paddles or fins, to improve collection, and inclined to the radial, Fig. 4 (not shown). In a modification, the centre of the collector rings may be disposed along a curve. In another modification, Fig. 5 (not shown), perforated discs are used for the collector elements. Paddles or fins may also be used in this embodiment inclined to the lateral surfaces. In another modification, Fig. 6 (not shown), the resonator body has a projection to incline the E.S. field. The collector rings have liquid cooling by making the rings of Fig. 1 and similar embodiments hollow, or over them if the members are flat perforated discs as in Fig. 5.

Title: Recovery of cooking liquor from spent semi-chemical pulping liquors
IPC: D21C11/00
Filed: 1953-02-05
Abstract: Sodium sulphite is recovered from spent semi-chemical pulp liquor by oxidizing said liquor under the vapour pressure of the reaction mixture and in the liquid phase in a reaction zone, reacting calcium bisulphite (added as such or formed in situ by introducing sulphur dioxide and an alkaline-reacting calcium compound such as the carbonate, oxide or hydroxide or the sulphite which is a by-product of the process) with the sodium-containing liquor formed in said reaction zone, separating the precipitated calcium sulphate, treating the filtrate with an alkaline-reacting calcium compound to form sodium sulphite and calcium sulphite and recovering the former.  In a modification the sodium sulphate is separated after the formation of sodium sulphite.  The oxidation is preferably performed by pumping the liquor into a tower reactor at 200-2000 lb./sq. in. and heated initially to 100-330 DEG C., preferably 235-250 DEG C. and passing a gas containing free oxygen, e.g. air, thereinto at a rate sufficient to ensure complete oxidation of the liquor.  The oxidized liquor is then passed through a flash chamber where gases are vented and some concentration takes place.  When calcium bisulphite is produced in situ, the mixture should be maintained at above room temperature, preferably at 12-25 DEG C, or more, and suitable pHs are less than 5, preferably 3-4.5.  In the second stage wherein an alkaline calcium compound is added, a suitable temperature is 70 DEG C. and a pH of 7-12 is generally obtained.

Title: Guest-host liquid crystal display device system and its application
IPC: G04G9/00
Filed: 1978-01-27
Abstract: An electronic clock with a guest-host liquid-crystal display is described. The specified drive electronics subject the guest-host liquid-crystal display to frequencies in excess of 32 Hz, preferably about 1 Hz. As a result, the power consumption of the guest-host liquid-crystal display is reduced to such an extent that there is no need for the previously used complex twisted nematic cell. Apart from the price advantage, the elimination of the previously necessary polarisers allows the proposed guest-host liquid-crystal cell to have a greater viewing angle for the display. <IMAGE>
