Patent GB-872259-A (GB)
Title: Improvements relating to gas chromatography
IPC: G01N30/88
Filed: 1959-10-07
Abstract: <PICT:0872259/III/1> A gas chromatographic analyser comprises two contiguous compartments, one of which carries a valve for controlling the flow of carrier and sample gases, and the other of which contains a motor operating said valve to take a sample and direct it with the carrier gas through a column which is supported in heat conducting relationship on a wall of good thermal conductivity of the first-mentioned compartment.  In the illustrated embodi <PICT:0872259/III/2> ment (Fig. 1), the column is in the form of a coil 14 wound on a mandrel 13 supported by a plate 12 which divides the apparatus into an upper and a lower portion.  On the mandrel is supported a block 16 comprising the sensing and reference chambers 56, 57 (Fig. 3) of a thermal detector provided with thermistors 58, 59, and the various gas connections are made by co-operation of valve 15 which has milled slots 37, 38, 39 in its base.  Carrier gas, e.g. helium, enters the base of the apparatus through line 41 and passes to the block 16 through flow regulator 20, flow restrictor 17 and preheater 43; sample gas enters the apparatus through line 48 and is passed through preheater 49 to the block 16.  In the position shown in Fig. 3, sample gas is not being passed to the column but through a sample tube 47 to discharge 53.  Meanwhile the carrier gas is passed through the column and the sensing and reference cells, (the latter being reached through valve 61 to reduce the pressure to atmospheric) and thence to outlet 55.  On rotation of the valve the carrier gas is directed through sample tube 47 before being passed to the column thereby carrying the sample into the column, while sample gas passes directly to the outlet 53.  The carrier gas in this case also flows through the reference cell 59 of the analyser.  The preheater coils 43, 49 and the column 14 are maintained at the desired temperature by means of a 350 watt fast heater 22 in the wall of the mandrel controlled by a bimetallic thermostat in the bottom of the mandrel, and six heaters 24 controlled by a mercury thermostat in a slot in the side of the mandrel.  A base heater may also be provided and a suitable circuit diagram for these heaters is shown.  The valve 15 is operated by a motor 18 which is controlled by a switch operated in turn by a programmer as described and claimed in Specification 872,260 which also controls the electrical apparatus leading to a final result on a recorder. The apparatus may be programmed to provide bar graphs of the constituents of repetitive samples or a continuous recording of the sample gas in conventional form.  The apparatus is enclosed in a housing, and the upper compartment in an explosion-proof cover.

Title: Process for the recovery of chlorine
IPC: C01B7/01
Filed: 1972-07-21
Abstract: 1407034 Chlorine; ferric oxide LAPORTE INDUSTRIES Ltd 20 July 1973 [21 July 1972] 34363/72 Heading C1A A process for the recovery of chlorine from ferrous chloride comprises contacting ferrous chloride vapour with a quantity of oxygen in excess of that required stoichiometrically for the conversion of the ferrous chloride to ferric oxide and passing the resulting mixture through an essentially empty reactor (i.e. containing no solid packing) at a temperature controlled at a sufficiently high level to prevent condensation of the ferrous chloride during at least the first two seconds of residence of the mixture in the reactor and at a velocity sufficient to entrain the particles of ferric oxide produced and separating the chlorine produced from the particles of ferric oxide. The essentially empty reactor is one containing no solid packing. The ferrous chloride vapour may contain inert gases (such as carbon oxides) and a minor quantity of ferric chloride. Preferably the reaction temperature is at least 30‹ and not more than 200‹ C. above the dew-point and is not allowed to rise above 1300‹ C. Up to 2À5 moles and preferably 0À8 to 2À0 moles of oxygen per mole of ferrous chloride is present. The ferrous chloride vapour may be effluent from a titaniferous ore chlorination and the chlorine product may be used in the chlorination of further ore. In the examples gases from fluidized bed chlorinator 10 in furnace 11 emerge through pipe 12 and contact oxygen fed in at 13. Ferric oxide of particle size 5 microns is entrained and is collected in cyclone 17.
Patent GB-605353-A (GB)
Title: Improvements in or relating to tuning devices for superheterodyne receivers
IPC: H03J3/28
Filed: 1945-12-20
Abstract: 605,353. Inductances. PHILIPS LAMPS, Ltd. Dec. 20, 1945, No. 34501. Convention date, Dec. 5, 1940. [Class 38 (ii)] The desired frequency difference between the tuning of local oscillator and the preliminary circuits of a superheterodyne receiver is maintained throughout the range by making the oscillator coil and its core longer than the other coils and cores; the oscillator core is adjustable as to its initial position and still extends into its coil when the others are entirely withdrawn. As shown, coils 1 and 2 having cores 4 and 5 serve to tune two high-frequency circuits of a superheterodyne receiver while coil 3 with core 6 tunes the oscillator. The frequency difference between the oscillator circuit and the other circuits is mainly determined by the nature of the cores and the larger diameter of the oscillator coil 3. Tracking is further improved by making core 6 longer than the other cores, and arranging for core 6 to enter coil 3 before the other cores enter their coils. Core 6 is adjustably mounted on the common operating bar 7.

Title: Improvements in and relating to the activation of carbon by means of gases
IPC: C01B32/336
Filed: 1927-12-21
Abstract: 283,573. Soc. de Recherches et d'Exploitations PÚtrolifÞres. Jan. 14, 1927, [Convention date]. Carbon. - In activating carbon by means of gases at high temperatures the carbon is impregnated or mixed prior to or during activation with an agent having ignifuge or fireproofing properties and being fusible or adapted to give rise to fusible compounds at the activating temperature in an amount not exceeding 5 per cent by weight. The carbonaceous material treated may be in the raw state, or wholly or partly carbonized or activated and may also be naturally or artificially agglomerated. The agent may be added in solution form by atomizing it into or mascerating it with the carbon, or in a dry powdered condition. The impregnating agent may be phosphoric acid, alkali phosphates, boric acid, borate, carbonate, bisulphate, or silicate of soda and caustic soda. To produce a moulded activated carbon, the carbon, active or inactive, is, ground, mixed with a binder such as sugar, bisulphite cellulose liquor, coal tar, wood tar, oxidized tars, dextrin, algine. gum arabic, iron gels, alumina or calcium sulphate, and a small amount of the fireproofing agents mentioned above, alone. or together, is added to the paste obtained and the material moulded, dried, calcined, and activated. In another method, carbon impregnated or agglomerated with organic substances, coked, and ground, is reagglomerated, the impregnating agents being added at either or both agglomerating &c. treatments, and the material after finally drying and calcining is activated, and may also be coated according to the process of Specification 261.692, giving a carbon or high density and strength. The ash content of the carbons may be reduced by washing before or after activation. Specifications 216,761, 279.104. and 291,725 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the addition to the carbon to be activated of agents, having little or no fireproofing properties, which are infusible or volatile at the activation temperature. To obtain a light, black and soft decolourizing carbon, wood charcoal is impregnated with traces of ferric chloride, zinc chloride, or hydrochloric acid, or is washed with water to remove ash before activation. The ash content of the activated carbon may be reduced by volatilization at high temperatures. In some cases the ash content of the primary material may be increased. This subjectmatter does not appear in the Specification as accepted.

Abstract: A bleaching composition comprising a quick-dissolving agglomerated sodium perborate is prepared by (a) forming a particulate mixture of a finely divided sodium perborate tetrahydrate having an average by weight particle diameter of 30-300 microns and a finely divided hydratable inorganic salt having an average by weight particle diameter of 20-400 microns selected from sodium pyrophosphate, sodium carbonate, trisodium orthophosphate and disodium orthophosphate, the corresponding potassium salts, sodium tripolyphosphate and mixtures thereof, (b) allowing the particles to fall freely in a broad, thin, curtain like-stream (c) spraying on to the particles in the curtain, as an agglomerating agent, a sodium silicate solution in a finely divided form having an average by volume droplet diameter of 20-150 microns, and being of the same magnitude or smaller than the particles of hydratable inorganic salt and/or perborate, the ratio of SiO2 : Na2O in the silicate being from 2.6 : 1 to 3.8 : 1 and the percentage of water in the solution being 55-70% by weight, (d) contacting the particles with each other in a tumbling bed so that the perborate particles and hydratable inorganic salt particles are agglomerated, the hydratable inorganic salt dehydrating the silicate solution sufficiently for solid silicate bonds to be formed between the particles, the agglomerated particles of perborate, hydratable salt and silicate having an average by weight particle diameter of 200-700 microns and having a bulk density in the range 0.4-0.7 grams per cubic centimetre, the particles in the curtain falling with a vertical velocity less than that achieved in a free fall of 10 feet starting with zero initial vertical velocity and the thickness of the tumbling bed being less than 20 inches.  The terms "average by weight particle diameter" and "average by volume droplet diameter" refer to the diameter of a spherical particle or droplet having the same weight or volume as the average weight or volume of the particles or droplets.  The curtain may be formed in a rotating drum having multiple baffles or by letting the particles fall free from a simple hopper or from the end of a conveyer belt.  When a rotating, baffled drum is used the tumbling bed is formed by having sufficient particulate material present in excess of that required to form the falling curtain to maintain in the lower part of the drum a bed of the desired thickness.  When the falling curtain is formed by other means the tumbling bed may be formed in a rotating substantially horizontal drum into which the curtain is directed.  The perborate is preferably present in the finished agglomerate in an amount of 40-90% by weight and the inorganic salt in an amount of 5-40% by weight on an anhydrous basis.  5-40% by weight of the silicate solution is preferably sprayed on to the curtain so that the final aglomerate contains 1.5-18% by weight of the silicate.  The perborate-hydratable salt mixture or the silicate solution may contain other inorganic salts or dyes.
