Patent GB-833888-A (GB)
Title: Improvements in head-pieces for pressurised clothing
IPC: A62B18/04
Filed: 1957-09-05
Abstract: A head-piece for a pressurized suit, worn over a respirator or crash-helmet at low atmospheric pressure, is formed of flexible material and has a transparent visor.  The head-piece is erected, closed and sealed by a system of rubber tube incorporated in the material and connected to a compressed gas supply.  The erection of the neck and rear, the closing of the visor and the sealing take place in sequence by the operation of valves mounted in the rubber tubing and which open at predetermined pressures to admit gas into the tubes in each section in turn.  The engaging edges of the visor and head-piece overlap and are urged tightly together by the tensioning action of the pressurized tubing in each edge.

Abstract: 485,533. Printing-machines. HADDAN, R. (Duplex Printing Press Co.) Oct. 15, 1937, No. 28148. [Class 100 (ii)] A multi-unit rotary newspaper printing press is built up of a number of perfecting or multicolour units in which tubular printing-plates are used, each unit being capable of perfecting two webs simultaneously, perfecting one web in multi-colour, or printing two webs in multicolour. The units are built up so as to permit of ready accessibility to the parts, and each unit is formed of four impression cylinders 1, 1a, 2, 2a and four printing cylinders 3, 3a, 4, 4a, of which at least one pair is arranged below the impression cylinder. In Fig. 3, the other pair of plate cylinders 3, 3a are arranged with their axes in the same horizontal plane as the axes of the impression cylinders. In all cases the inking mechanisms are arranged below the plate cylinders. In Fig. 1, the unit is shown as used for perfecting two webs W, W<1> which after being printed are led over rollers 12, 12a to the folding units. Each web is led outside of the lower sets of inking mechanisms and inside the upper set. The web W may be led first over the rollers 1, 1a then over a guide roll 10 and around the two rollers 2, 2a to receive a perfected multi-colour impression. Other leads of the webs may be used ; e.g. a web W may be perfected by being led around the cylinders 1, 1a, Fig. 3, and then led around guide-rollers 10c, 10a to receive one or two further impressions from the upper couples.

The suspension flow may be on the upper side or under side of the screen and as shown in Fig. 2 the discharge outlets 15 of throughput compartments 14 may also open into a common space 13 the outlet C of which is controlled by valve 18. A screening deck which is curved in a plane normal to the line of flow may also be used, Fig. (not shown). Examples of the separation of sand in water and coal in water are given and as the relative pressure on the feed side of the deck increases so the particle size of the throughput increases.

Patent GB-736146-A (GB)
Title: Improvements in or relating to the manufacture of sulphuric acid
IPC: C01B17/90
Filed: 1951-12-04
Abstract: In a process for manufacturing sulphuric acid using nitric oxide by burning gases containing hydrogen sulphide and nitrogen-hydrogen compounds with air to gases containing sulphur dioxide and water vapour, the combustion is carried out with a limited excess of air, e.g. up to 100 per cent excess of the theoretical amount for complete combustion of all the combustible constituents of the gases at temperatures above 1150 DEG  C. with formation of nitric oxide and the combustion gases are cooled immediately after formation of the nitric oxide to a point where nitric oxide is not decomposed to any appreciable extent, say 320 DEG  C., and the cooled gases, without any or any substantial addition of nitric oxide or nitric acid, are afterwards treated in a lead chamber, tower, or other NO-system to form sulphuric acid.  The nitric oxide in the gases is sufficient to maintain the nitrosyl content of the circulating chamber or tower acid constant for some time.  The hydrogen sulphide gases may be any commercial gases, such as those from wet desulphurization of coke-oven gas, working up crude oils, or hydrogenation of coal or oil, which contain hydrogen cyanide and ammonia.  Cooling may be effected by passage through a waste heat boiler.  The air passed to the burner may be preheated.

Title: A process for the production of high-strength threads from regenerated cellulose
IPC: D01F2/08
Filed: 1957-09-13
Abstract: High-strength threads are made by spinning viscose in a precipitation bath containing sulphuric acid, sodium sulphate and zinc sulphate and then stretching or finally decomposing the threads in a hot bath, the acid concentration in the precipitation bath being not greater than, and not more than 2% below the percentage of alkali in the viscose, the total proportion of salts in the precipitation bath being from 10-23% by weight, based on the weight of the said bath and the ratio of the percentages of sodium sulphate and zinc sulphate in the said bath being from 0.9-2.5 Part of the zinc sulphate may be replaced by ferrous sulphate, the proportion of zinc sulphate being then not less than 3% of the weight of the precipitation bath, and the salt sum and salt quotient are then calculated on the sodium sulphate and the combined weights of zinc and ferrous sulphates.  Preferably, the temperature of the precipitation bath is from 30-80 DEG  C., and especially from 30-45 DEG  C.  The viscose and (or) the precipitation bath may contain known additives, e.g. primary amines, polyamines, quaternary ammonium bases, thiocarbamates, imidazoles, thiazoles, polyethylene glycols, and condensation products of ethylene oxide with fatty amines, fatty acids, fatty alcohols or phenols.

Title: Improvements relating to separating apparatus employing counter-current flow through vertical conduits
IPC: B01D11/04
Filed: 1949-11-11
Abstract: <PICT:0676023/III/1> <PICT:0676023/III/2> In fractionating columns and similar countercurrent liquid/vapour contacting apparatus comprising a plurality of vertical conduits arranged in parallel, fixed guiding devices are distributed through the length of the conduits in such a manner and so arranged to impart turbulence to the rising stream of vapour along the centre of each conduit but only to disturb to a minimum the falling stream of liquid along the wall of the conduit. Fractionating column 10, Fig 1, contains a closely-packed bundle of vertical conduits 11 (only two are shown) distributed over the whole cross-section of the column.  The vapours are supplied to the column through pipe 17 leading from a still (not shown).  The vapours are uniformly distributed by means of porous-filling 21 supported between perforated partitions 20, and then enter conduits 11.  Reflux-liquid is formed in the upper eds of conduits 11 which pass through cooling-chamber 22.  The reflux flows down the walls of the conduits.  The upper ends of the conduits terminate in choke-tubes 25 of narrow bore, which communicate with chamber 26.  The components of low volatility are withdrawn through pipe 19, while those of high volatility are withdrawn through pipe 27.  In order to ensure good interchange between the rising vapour and the reflux, each conduit is provided with fixed propellers 35, Fig. 2, arranged at intervals on a wire 36 in such a manner that adjacent propellors are displaced by 90 degrees. The tips of the propellors are twisted so that they run parallel with the axis of conduit 11 whereby the reflux will flow round these tips with a minimum of disturbance.

Class 46 [Also in Group II] A method of effecting the controlled addition ot solid materials to a liquid flowing through a pipe consists in directing the flow of liquid in the pipe against a variable orifice which communicates with an enclosed supply, above the orifice, of the powders in suspension in a liquid. As described the liquid flows through the horizontal limbs 18, 19 of a T- connection 17 in the pipe and the solid materials are placed in a closable container 1, valves 15 and 23 then being opened so as to allow liquid to flow from the T-connection 17 into the container where it expels the air and forms a column of admixed liquid and solid in the container. The valves 15 and 23 are then closed to permit the solid materials to settle after which the valve 15 is opened to any required degree, thereby exposing the lower face of the column to liquid flowing over the top of a partition 22 as it passes through the limbs 18, 19 of the T- connection, the entrainment of solid materials . in the flowing liquid being assisted by turbulence created by the partition 22.
