Title: Improvements in or relating to the protection of iron and steel against fretting corrosion
IPC: C23F11/10
Filed: 1955-02-16
Abstract: A method of protecting iron and steel surfaces against fretting corrosion comprises applying to the surface a penetrated monolayer film formed by sensitized adsorption. A penetrated monolayer is a monomolecular layer of a weakly polar amphipathic substance, which has adsorbed a more strongly polar amphipathic substance. Sensitized adsorption is the adsorption of such a strongly polar substance (the sensitizer) by a metal surface to facilitate the subsequent adsorption by the surface of the weakly polar substance. An amphipathic substance is one whose molecules contain a polar portion and a non-polar portion. The iron or steel surface may have formed thereon by heat treatment or by chemical treatment a porous film, e.g. an iron oxide or phosphate, of which extends the range of sensitizers which may be used. Examples of sensitizers are alkyl or aryl sulphates, sulphonates, phosphates, phosphonates, amine or substituted amine, or salts of fatty acids, and the second substance is a sterol, e.g. cholesterol or alkyl or aryl alcohols or amines. The two compounds may be applied to the surface simultaneously as an oil-water emulsion, e.g. equal volumes of sodium dodecyl sulphate in water and cholesterol in British Pharmacopeia paraffin. An alternative emulsion, applied to a phosphated mild steel surface, was 0.36 gm. cetavlon in 100 mils water and 0.39 gm. cholesterol in 100 mils British Pharmacopeia paraffin. The emulsion may be heated to 60 DEG C. during application to the surface.

Title: Aromatic p, p'-diorthophosphoric acid monoesters
IPC: C07F9/12
Filed: 1961-07-07
Abstract: The invention comprises compounds of the general formula <FORM:0991018/C2/1> wherein R is a straight chain saturated hydrocarbon radical having a chain of 4 to 10 carbon atoms and A is a hydrogen atom or a salt-forming cation with the proviso that not all the symbols A need be alike. They may be obtained by hydrolysing, generally with water, an acid tetrahalide of the general formula <FORM:0991018/C2/2> and, when a salt is to be produced, treating the resulting acid ester with an organic or inorganic base. The cation A may suitably be an alkali metal ion or an organic base ion, e.g. of ethanolamine, triethanolamine or colamine or other physiologically acceptable base. The alkali metal salts may be obtained by dissolving the corresponding free acid ester in ethanol and mixing with a solution of sodium or potassium ethanolate, the mono-, di-, tri- or tetra-alkali metal salt being obtained depending on the amount of alkali metal present. In order to obtain the tetra-alkali metal salt, a tertiary base, e.g. pyridine should be present. Examples are given for the production of p,p1-diphenyl - 1,4 - n - butane - diorthophosphoric acid monoester and p,p1-dihydroxy-1,6-diphenyl - n - hexane, diorthophosphoric acid and its tetrasodium, tetraethanolamine, tetracolamine and tetra-triethanolamine salts. The products of Formula I may be purified via their alkaline earth metal, lead, or copper salts. The compounds of Formula II may be obtained by reacting a compound of the formula <FORM:0991018/C2/3> with a phosphorus oxyhalide, e.g. oxychloride r oxybromide, if desired in the presence of tertiary organic base, e.g. pyridine or quinoline. The products of Formula I are useful for treating prostate diseases and may be used in admixture with an inert pharmaceutically acceptable carrier.

Title: Multiple effect evaporation process
IPC: D06L3/08
Filed: 1964-06-24
Abstract: Volatile solvent is separated from a solution of a non-volatile salt by contacting the solution with a hot immiscible fluid in a series of evaporation zones 5, 23..48 each of which is maintained at a pressure below that in the preceding zone the solvent vapours formed in each evaporation zone (except the last) are conducted through a line 14, 24 .. into an associated condensation zone 15, 25 .. where they are contacted with cool heat-exchange liquid which has been used as heating-medium in the succeeding evaporation zone. In zones 15, 25.. the vapours condense and give up heat to the heat exchange liquid and, after separation from condensate in a phase settler 19, 37.., the heat exchange liquid is then returned (after vaporization if necessary) to the evaporation zone from which it was withdrawn. If the heat transfer fluid is introduced into an evaporation zone as a vapour, it condenses to a liquid which separates as a separate layer from the feed solution residue. An example is given of a seven-stage process for the production of salt-free water from sea water using diphenylethane (or decafluorobiphenyl) as heat transfer liquid. The absolute pressure in the first evaporation zone is 8 atmospheres, while the last zone is at about atmospheric pressure. The process may also be employed to separate organic solvents such as acetone, ether, hexanol or benzene from solutions using a molten metal, or metal halide, as heat exchange liquid. The solution to be treated is introduced into the apparatus shown through line 1 and flows, via line 68, through heat exchangers 66 and 54 where it is preheated by the heat-transfer liquid, withdrawn from settler 60, and by the concentrated solution withdrawn from settler 49, respectively. Alternatively, the feed solution is preheated by passing it through coil 75 in the condenser 59 of the last stage. The preheated solution flows through line 74 to the first evaporator 5 where the solution is contacted with heat exchange liquid which is continuously circulated through heater 12, evaporator 5, settler 7 and back to heater 12. Purified solvent is withdrawn from the system via lines 27, 38..61 on the condensate on settlers and residual concentrated solution is discharged via a line 57 on heat-exchanger 54.

Title: Apparatus for continuous and simultaneous measurement of concentration in the atmosphere of the shortlived solid decay products of radon
IPC: G01T1/178
Filed: 1968-04-10
Abstract: The concentrations of the short lived decay products of radon in the atmosphere are measured by depositing them on an intermittently moving filter strip, subsequently detecting separately the [alpha] and # particles emitted from the deposit, applying the [alpha] pulses to a two channel pulse height analyser to separate the components due to RaA and RaC1 and subtracting the RaC1 component from the # pulses to provide a measure of the RaB component. Sampling and detection apparatus. A filter strip 1, Fig. 3 extends between spools 2, 3, and passes through a sampling tube 6. At the start of a sampling interval, the inner tube 13 is lowered by an armature 11 to clamp the strip at the bottom of the tube 6 and the pump 8 is actuated to draw air through the filter strip. A punch 12 makes a perforation a distance D along the strip from the centre of the tube 6. At the end of the sampling period a cam switch 14 closes energise the solenoid 10 to raise the tube 13 and punch 12 and change over from the pump 8 to the pump 9. When the punch 12 closes the switch 20 an electromagnetic clutch 5 operates to move the strip until the perforation is detected by a photo-resistor 17. The deposited sample is then between a semi-conductor junction [alpha]-particle detector and a #-sensitive geiger tube 22 having an [alpha] opaque window (4mg/cm2 mica). Geiger tube 22 is surrounded by a compensating geiger tube 23, the outputs of the two tubes being connected to an anticoincidence circuit to eliminate background. Electrical circuit. The output of the [alpha] detector 21, Fig. 4, is fed through amplifiers 24, 25 to a pulse height analyzer 26, 27 and pulses due to RaA and RaC1 are each shaped (28, 29), integrated (30, 31) and applied to a recorder 34 which records them sequentially. The output of the # detector 22 is shaped at 40 and integrated at 41 and applied at T to recorder 34. The # output depends on both RaC and RaB. The RaC1 signal from integrator 31 is multiplied by 1À0004 at 43 to become representative or RaC and then subtracted from the # signal by connecting the signals to opposite ends of potentiometer 47 and the difference applied to recorder 34 at B as a signal representative of RaB. An extra channel may be provided whereby the total [alpha] count may be recorded.
