Title: Manufacture of vermin-destroying compositions, and their application
Filed: 1945-05-31
Abstract: Textiles, feathers, wool, hair, pelts, skins cereals, seeds, wood, paper, leather, &c. including articles thereof such as fabrics, yarn, clothes, and linen are proofed against insects by treatment with a composition containing an ether of the formula R-(O-CHCl-CCl3)n, wherein R means an aliphatic, cyclo-aliphatic, ariliphatic, or hetero-cyclic radical which may be unsaturated or substituted.  The ether may be admixed with, say, bentonite, bole, chalk, keselguhr, talc, powdered cork or sawdust with or without a dispersing agent to form a wettable powder for a liquid spray, or may be dissolved in an inert high boiling organic liquid such as mineral or vegetable oil, e.g. kerosene, or it may be formed into a suspension or emulsion or concentrate ready to form an emulsion.  Thus the ether may be dissolved in say a mineral or vegetable oil, tetrachlorethane, methyl hexaline, tetrahydronaphthalene, or ethylene dichloride to which an emulsifying agent is added; or it may be dissolved in the emulsifying agent itself.  Emulsifying agents specified are soaps, Turkey red oils, quaternary ammonium salts, sulphonated fatty alcohols and saponified colophony.  Other substances such as phthalonitrile, thiourea or thiourea derivatives, thianthrene, sulphur, copper compounds, nicotine, rotenone, and pyrethrum extract may be present, as well as stickers, e.g. casein, fatty acid salts, rosin and glue, and spreaders and dust-binding agents. The ether may also be dissolved in a liquid which normally boils below room temperature. Inert organic carrier liquids may also be present.

Patent GB-804967-A (GB)
Title: Improvements in or relating to heat exchange processes in hydroforming
IPC: C10G35/06
Filed: 1957-04-30
Abstract: In a hydroforming process in which hot vaprous products containing fouling material are passed through a heat exchange zone to heat naphtha feed and fouling material is deposited on heat exchange surfaces, a hydrocarbon solvent liquid is introduced for an interval into the stream of hydroformate products ahead of the fouled heat exchange zone to cool the zone so that the solvent contacts the fouled surface as a liquid, thereby softening and loosening the fouling material which is blown away by the continued passage <FORM:0804967/IV (b)/1> of vaporous products.  In a preferred embodiment, hot vaporous hydroformate from line 24 is split into two streams 26 and 28 which pass respectively through heat exchangers 34 and 102, and 32 and 105.  Naphtha feed passes through exchangers 105 and 34, and hydrogen-containing recycle gas through exchangers 102 and 32. The cooler exchangers 102 and 105 become fouled by finely-divided catalytic material carried over by the hydroformate. Sufficient wash liquid at 85-450 DEG  F. is introduced by lines 120 and 122 to cool the heat exchangers so that the interiors of the exchangers are contacted with the solvent in liquid form, the introduction of solvent being carried on for 30 minutes to 2 hours every 3 to 12 days as necessary.  The solvent used may be naphtha feed or unstabilized hydroformate product, but preferably is polymer bottoms obtained by fractionation of the hydroformate having for example a boiling range of 184-707 DEG  F.  The heat exchangers may be vertical cylinders containing bundles of tubes through which the hydroformate vapours pass and can be arranged in connected pairs the vapours passing down through one and upwards through the following one.  In an example, hot vapours entered line 24 at 883 DEG  F., leaving exchangers 32 and 105 at 575 DEG  and 434 DEG  F. and exchangers 34 and 102 at 516 DEG  and 445 DEG  F. respectively, and the pressure drop across each exchanger 102 and 105 was 4 p.s.i.; naphtha feed was heated from 320 DEG  to 647 DEG  F. and recycle gas from 245 DEG  to 730 DEG  F. in the heat exchangers.  After 32 days, the temperature of vaporous products leaving exchanger 102 had dropped to 397 DEG  F. and leaving 105 had risen to 489 DEG  F., and the pressure drop had risen to 8.9 p.s.i.  About 45 barrels of naphtha feed of boiling range 200-360 DEG  F. at 100 DEG  F. were pumped into each of lines 120 and 122 over about 2 hours after which the temperatures of vapours leaving exchangers 102 and 105 were 453 DEG  and 477 DEG  F. respectively and the pressure drop was reduced to 5 p.s.i.  The use of 45 barrels of unstabilized hydroformate at 100 DEG  F. injected through each of lines 120 and 122 over 2 hours was also effective, as was 45 lbs. of hydroformer polymer at 420 DEG F.

Title: Improvements in means for regulating the flow of fluid into an enclosure
IPC: G05D7/01
Filed: 1948-02-13
Abstract: 684,589. Fluid-pressure servomotor-control systems. GARRETT CORPORATION. Feb. 13, 1948 [April 23, 1945], No. 13783/51. Divided out of 684,554. Class 135. Means for regulating the flow of fluid into an enclosure such as an aircraft cabin, comprises a duct 11 arranged between the enclosure 10 and a source of fluid pressure, such as the supercharger 5, a spill valve 16 located in the duct and biased to the closed position, e.g. by a spring 54, a valve balancing member, such as the diaphragm 18, to chamber 23 on the outer side of the valve balancing member having a restricted connection 68 with the atmosphere, and differential pressure responsive means such as the diaphragm 25 adapted to control the admission of air into the chamber 23 from a region of higher pressure to open the valve 16. The duct 11 itself provides the source of higher pressure and this pressure is conveyed through passages 66, 67 to the chamber 23 under the control of a valve plunger 63 which regulates a port 65 and is pivoted to a lever 74 the ends of which are pivoted to a stem 71 attached to the diaphragm 25 and to a stud 80 adjustably connected by a sleeve 81 to an extension 79 of the spill valve stem 17. The valve plunger 23 thus moves under the influence of the pressure difference acting on the diaphragm 25 and is re-set by the movement of the diaphragm 18. When the valve 16 is closed, the duct pressure acting on its inner face is substantially balanced by the duct pressure on the adjacent face of the diaphragm 18 whilst atmospheric pressure acting on the outside of the valve is balanced by the atmospheric pressure prevailing in the chamber 23 due to the port 65 being closed. The differential pressure on the diaphragm 25 is created by the air flow through a venturi 9 connected with a cooler 8 between the duct 11 and the enclosure and in effect forming part of the duct. The pressure difference between the inlet and throat of the venturi is a measure of the mass rate of air flow to the enclosure 10 and the spill valve thus operates to prevent a predetermined rate being exceeded. The inlet and throat of the venturi are connected by pipes 32, 31 to chambers 27, 26. The assembly also comprises a casing section 19 with an extension 70, a casing cover 61, and a casing section 22.

Title: Process for preparing precipitated products
IPC: C01F11/18
Filed: 1958-05-05
Abstract: Pigmentary calcium carbonate is precipitated by contacting calcium ions and carbonate ions in an aqueous solution having a pH of at least 8.5 and the resulting precipitate is subjected to the shearing action of a stator and rotor of which the minimum peripheral relative speed is 1160 feet per minute.  The precipitation is preferably effective at 25 DEG  to 60 DEG  C. and the calcium ions may be furnished by milk of lime or calcium <PICT:0860959/III/1> chloride and the carbonate ions by carbon dioxide or sodium carbonate. Crystals produced in this temperature range are elongated in shape and calcitic in structure.  If precipitation is effected at - 10 DEG to 25 DEG  C., the calcium carbonate crystals are cubic in shape; at above 60 DEG  C. the crystals are needle-like in shape and are aragonite in structure.  A suitable apparatus is shown in Fig. 2 where a reactor formed by cylindrical side-walls 16 and a hemispherical base 14 is provided with a rotor and stator arrangement generally indicated by 24.  A stationary annular disc 32 has an outer and inner peripheral ring of teeth 34 and 36, embracing the upward extending teeth 40 of a rotor member 38 which is joined to the central shaft 44 by pumping blades or vanes 42.  A solution bearing calcium ions is fed through a conduit 50 and the solution of carbonate ions is fed through conduit 56 which ends in a gas sparger 60.  Product calcium carbonate is withdrawn at 68.  Examples refer to the production of calcium carbonate by feeding milk of lime and carbon dioxide gas and to preparation by feeding calcium chloride solution with a solution containing sodium carbonate and sodium bicarbonate.  A comparative example illustrates that the reaction between calcium chloride and a sodium carbonate/bicarbonate mixture will result in a calcium carbonate gel if vigorous agitation is not applied.

Patent GB-771583-A (GB)
Title: Oxidation of propanol and butanol
IPC: C07C51/27
Filed: 1955-05-18
Abstract: Propionic and butyric acids are obtained by oxidizing propanol and butanol respectively with aqueous nitric acid.  The concentration of the nitric acid present in the mixture may be from 35 to 85 per cent by weight and is preferably between 60 and 70 per cent, e.g. 65-70 per cent, calculated with respect to all the water present in the mixture.  About 3 to 10 parts by weight of nitric acid (calculated as 100 per cent nitric acid) should preferably be used for each part by weight of alcohol.  The oxidation is preferably carried out at between 10 DEG  and 45 DEG  C., e.g. between 10 DEG  and 30 DEG  C. and an oxidation catalyst such as ammonium vanadate may be present. It may be carried out as a batch process, e.g. by slowly introducing the desired amount of alcohol into the aqueous nitric acid and stirring vigorously. Preferably however, the oxidation is carried out continuously, e.g. by forming a mixture of the aqueous acid and the alcohol and passing it through a vessel in which the oxidation is effected. There may also be added to the mixture at the start of the oxidation an amount of 1 to 20 per cent by weight based on the total weight of the mixture, of a mixture previously obtained by the same reaction.  It is not necessary that the reaction should have been completed in this added mixture.  The reaction products can be separated by distilling off the azeotropic mixture of the aliphatic acid and water from which the acid can be recovered by solvent extraction, e.g. with a mixture of benzene and ethyl acetate.  A small amount of a lower aliphatic acid containing fewer carbon atoms than are present in the alcohol charged is also formed in the reaction.  Examples are given for the production of propionic acid together with a small amount of acetic acid from propanol and of butyric acid together with a small amount of propionic acid from butanol.
