Patent GB-845699-A (GB)
Title: Heat exchanger
IPC: F28F9/02
Filed: 1958-10-08
Abstract: An evaporator comprises a shell 1 enclosing a central conduit 7 and pipes 8, liquid to be vaporized being passed down the central tube from an inlet 11 into a chamber 6 and up the pipes 8, in which latter heat is absorbed countercurrently from a heating medium which enters the evaporator at inlet 16 and leaves at outlet 17, baffles 18 causing the medium to zig-zag through the space around the pipes.  A tube 19 is arranged concentrically around, and with slight clearance from the central conduit 7, the tube covering part or, as shown, all of the conduit, the tube p  preventing any appreciable heat exchange between liquid in the central conduit and the surrounding medium. The space between the conduit 7 and the tube 19 is sealed at one end, there being a slight clearance from a floating head 4 at the other end.  The vapour formed and unvaporized liquid are collected in and discharged from a chamber 12.

Patent GB-617931-A (GB)
Title: Improvements in the production of cellulose esters
IPC: C08B3/10
Filed: 1946-11-06
Abstract: Cellulose derivatives containing radicles of higher fatty acids, i.e. saturated or olefinic fatty acids containing at least six carbon atoms, are made by treating cellulose or an esterifiable derivative thereof with an esterifying derivative of the acid in the presence of zinc chloride, hydrogen chloride and a solvent for the cellulose derivative produced, and precipitating the product after neutralizing the hydrogen chloride, an essential feature of the process being that neutralization is effected with a suitable zinc compound, e.g. zinc carbonate or a zinc salt of a fatty acid, or with a reagent which introduces no cation into the solution, e.g. an olefine (other than ethylene) or an olefine oxide.  Products of improved colour and clarity are obtained. Examples are given in which cellulose acetate-stearate is made by treating acetone-soluble cellulose acetate with stearic anhydride in ethylene dichloride containing zinc chloride and hydrogen chloride, and neutralization is then effected by addition of powdered zinc acetate or a solution of ethylene oxide in ethylene dichloride or by treating the solution with gaseous ethylene oxide or propylene; the ester is then precipitated by adding boiling water to the solution, and may be washed with a hydrocarbon or an ether, as described in Specification 605,912.  Other specified neutralizing agents are the butylenes and amylenes, but reference is made also, by way of comparison, to neutralization with sodium, ammonium or magnesium acetate or sodium or ammonium carbonate. Other specified products are cellulose laurate, palmitate, stearate, oleate, acetate-palmitate and propionate-stearate. Specification 562,691 also is referred to.
Patent GB-394679-A (GB)
Title: Improvements in or relating to the manufacture of cyclic ethers
Filed: 1931-11-30
Abstract: Cyclic ethers are produced by condensing aldehydes or their polymers or ketones with glycols or other polyhydric alcohols in presence of hydrogen sulphates, hydrogen phosphates, pyrosulphates or pyrophosphates, especially of the alkali metals.  The operation may be continuous, as described in Specification 394,678, the temperature being preferably maintained so that the ether distils off as it is produced; or a batch process may be employed.  The reaction mixture may be fractionally distilled, if desired after first adding sodium bisulphite to fix unchanged aldehyde and/or sodium carbonate to neutralize any acid present, and sodium chloride to separate water. The partially purified products, which contain dioxane, especially when free from aldehydes and acidity, may be used as solvents or swelling-agents for cellulose acetate and other cellulose derivatives.  A number of methylene and ethylidine diethers are mentioned as products.  In an example, glycol and paraformaldehyde are condensed by means of sodium bisulphate at 140 DEG  C., the process being continuous.  The distillate is treated with sodium bisulphite to remove aldehyde, sodium chloride to separate water, and anhydrous sodium carbonate to remove acidity; it is then dried with calcium chloride and re-distilled.
