Patent GB-278712-A (GB)
Title: Improvements in or relating to the separation of mixtures of gases and gases with vapors
IPC: B01D53/14
Filed: 1927-10-04
Abstract: 278,712. Blau, H. Oct. 5, 1926, [Convention date]. Grant of Patent opposed. Distilling plant and processes; column stills. -In a process for separating a mixture of gases of different solubilities in a liquid the compressed mixture is subjected to the action of the liquid so that the gas of higher solubility and part of the gas of lower solubility is absorbed, while by a subsequent rectification the constituent of lower solubility is entirely expelled from the liquid. The compressed and cooled mixture is introduced by a pipe 1 to the bottom of an absorbing column A down which the absorbing liquid flows, whereby, in the case for example of a mixture of carbon dioxide and nitrogen, an effluent of pure nitrogen is obtained at the top of the column and a liquid saturated with the more soluble carbon dioxide and containing a certain amount of nitrogen passes out at the bottom. The liquid passes on into a second column B wherein it is heated so that it arrives at the bottom of this deprived entirely of nitrogen but still containing carbon dioxide. The liquid then passes through a pipe 3 to a heat exchanger W and thence through a pipe 4 to an expeller C wherein it is gradually heated to boiling point, the expelled gas being drawn on at 5. The heated liquid is drawn off from the base of the expeller by a pump E, through the exchanger W and a cooler D, and returned to the absorber A. Where more than two constituents are to be separated a series of expellers is employed these having conveniently the construction of the apparatus A, B, i.e. a cooled section superposed on a heated section, the temperatures being selected so as to effect the desired fractionation. In separating mixtures of hydrocarbon gases a suitable liquid may be the hydrocarbons of boiling point in the neighbourhood of 100‹ C. contained in the gases. When the separated gases are not required to be used or stored they may be employed as motive fluid in an expansion engine. If the gases to be separated are readily liquefiable the pressure employed may conveniently be that or a little above that at which they are liquefied at atmospheric temperature.

Title: Voltage indicator tube
IPC: H01J31/14
Filed: 1951-11-02
Abstract: 742,466. Cathode-ray tubes. STANDARD TELEPHONES & CABLES, Ltd. Nov. 9, 1951 [Nov. 11, 1950], No. 26285/51. Class 39 (1). A voltage indicator tube has a tubular cathode 1, Fig. 2, grid 2, a pair of arcuate deflecting electrodes 4, 5 at the same radial distance from the cathode placed symmetrically on either side of a plane of symmetry of a bowl-shaped fluorescent anode 3, the said plane of symmetry passing through the axis of the cathode. The deflecting electrodes may also each be in two parts of L-section, Fig. 4, or may be formed as grids, Figs. 7-9 (not shown), the resulting fluorescent patterns being indicated. The input voltages to the deflecting electrodes may be pre-amplified by an amplifier section inside the tube envelope. The device may be used in amplitude or frequency modulated receivers. In the latter case the deflecting electrodes are connected to points on the discriminator and carry equal voltages only when the receiver is tuned to the carrier frequency, which gives a symmetrical pattern. It is stated that if the grid 2 is connected to the grid circuit of the limiting stage, or to the noise suppressor or discriminator, the luminosity of the fluorescent pattern will vary depending upon whether or not the input signal has a carrier. The form of the pattern may also change if the deflecting electrode connections include resistors. For amplitude modulated receivers both deflector electrodes are connected together so that the fluorescent pattern will always be symmetrical. The central luminous trace will, however, expand as the deflector potential becomes more positive. Specification 703,660 is referred to.

Title: Improvements in telegraph signal transmitting apparatus having signal storage
IPC: H04L25/04
Filed: 1931-09-25
Abstract: 389,854. Type-printing telegraphy. CREED & CO., Ltd., Telegraph House, Croydon.-(Teletype Corporation ; 1400, Wrightwood Avenue, Chicago, U.S.A.) Sept. 25, 1931, No. 26752. [Class 40 (iii).] A telegraphic transmitter suitable for fire-alarm and like purposes comprises means for setting up or storing signals in a form in which they can easily be read off before transmission. Each numeral or other character is represented in 5-unit code by an axial row of contacts 15 on a sector 14, and each of the sectors 14 can be set by hand so as to bring a selected row of contacts 15 into engagement with the appropriate set of brushes 16. The sectors 14 are set by rotation about their axes 13, and to this end they are geared to corresponding setting-wheels 1 which are marked with characters corresponding to the rows of contacts 15. The message set up on the sectors 14 can therefore be read off the wheels 1 against the straight edge 2. Each sector 14 is associated with a set of five brushes 16, and each set of brushes is connected to a radial set of distributer contacts 21, so that successive radii of the distributer correspond to successive wheels 1. The five distributer brushes 27 are connected to distributer contacts 55, so that as the arm 67 rotates signals are sent to line 68 in correspondence with that row of contacts 15 which is connected to brushes 27 at the moment. The combination segments 55 are followed by a blank segment 61, a stop segment 62 which is connected to battery B, and a start segment 63 which is disconnected. The friction-driven distributer shaft 69 is held, in the stop position, by the armature 78 ; but when contacts 99 are closed by hand, magnet 79 is energized and distributer shaft 69 revolves. Once in every revolution its tooth 82 moves ratchet 83 through one step, thus moving the second distributer shaft 34 and changing the connections of distributer 26 from one set of brushes 16 to the next. The action continues throughout one revolution of the slow distributer shaft 34, the start magnet 79 being held on by cam-actuated contacts 93 until the revolution has been completed. The motor 75 may carry a stroboscopic or other speed-indicator 75<1>. The effective segments of the distributer 26 are preceded by blank segments, so that start and stop signals only are sent to line for, the first few revolutions, to ensure synchronism. The outgoing lead 68 may pass through the contacts of a keyboard transmitter before going to the line, and in that event the keys are locked by a locking- magnet 115, while the shown transmitter is sending.

Patent GB-890696-A (GB)
Title: Moulded synthetic detergent compositions
IPC: C11D1/14
Filed: 1958-11-24
Abstract: A moulded synthetic detergent composition consists of a moulded mass of one or more potassium n-alkyl sulphonates in which the alkyl groups contain 8-20 carbon atoms, the average carbon content being 12-16 carbon atoms; it is preferred that the alkyl groups should contain 14-16 carbon atoms.  The bars are obtained directly by preparing ammonium n-alkyl sulphonate and displacing the ammonium base completely with potassium (see Group IV(b)), then heating the sulphonate until the water content is 20-25% by weight, after which the thick slurry at 100 DEG C. is dropped on to a chilled roll where it solidifies, is then chipped off, and finally air-dried to a water content of 1-10%.  Potassium sulphate is generally present in the bars, which may also contain perfume and dye.ALSO:Potassium n-alkyl sulphonates in which the alkyl group contains 8-20 carbon atoms, the average content being 12-16 carbon atoms, and which are used in the manufacture of moulded synthetic detergents (see Group III), are obtained by completely displacing the ammonium base by potassium (e.g. by means of potassium hydroxide) in the product obtained by the free radical addition of ammonium bisulphite to the appropriate 1-olefins (suitably derived from the cracking of paraffin wax) in aqueous alcohol.  Unreacted hydrocarbons are removed by extraction with a light hydrocarbon, e.g. pentane, or by dilution with water followed by phase separation, before the ammonium base is displaced. After the formation of the potassium salt, alcohol is distilled off from the sulphonate layer, and the mixture heated until the water content reaches 20%-25% by weight; at this point the thick slurry at 100 DEG C. is dropped on to a chilled roll where it solidifies, is chipped off, and finally air-dried to a water-content of 1%-10% by weight.
