The foot support plate 11 is pivotally mounted so as to tilt slightly when a foot is placed thereon and to actuate a switch setting in operation the drive to the heel and toe abutment plates 15, 18. This drive is from an electric motor 29 by way a chain and sprocket drive and is arranged such that the two plates 15, 18 can make independently of each other, i. e. when one has contacted the foot on the plate 11, the other will continue to move until it too contacts the foot. The plates 15, 18 are mounted to operate switches on contact with a foot so that when both have been stopped by such contact the supply to the motor 29 will be cut-off. This also initiates the drive to the carriages 33, 34 which is also by electric motor and a chain and sprocket arrangement similar to that for the plates 15, 18. Removal of the foot from the plate 11 initiates return of the plates 15, 18 and carriages 33, 34 to their start positions at the edges of the plate 11. The movements of the plates 15, 18 as indicated by rotation of the motor 29 are transmitted to a flat slide 53 moving in parallel guides 51. The slide 53 is marked with scales 60 indicating childrens and mens and ladies shoe sizes and corresponding width fittings 63 adapted to be read off against a line 71 on a further slide 61 depending on the measured foot length. Movements of the carriages 33, 34 are transmitted by way of a gear 68 and an elongated gear 67 to a cable drive 66 to drive the slide 61 transverse to the guides 51. The slide 61 carries two arrow markings 62 to indicate which of the marked width fittings 63 is appropriate to the width of the foot being measured. The slides 53, 61 are transparent and a lamp 75 is provided together with a mirror (not shown) beneath the slides to project the correct shoe size and width fittings on to a translucent screen or other flat surface.

Title: Improvements in or relating to the refining of mineral oil and the preparation of lubricating oil
IPC: C10G21/04
Filed: 1933-07-13
Abstract: Mineral oils are separated into their paraffinic and naphthenic constituents by treating with a paraffinic and a general naphthenic solvent flowing in countercurrent, the two solvents being immiscible whereby the oil is separated into layers from which the respective constituents are recovered.  The paraffinic solvents used consist of petroleum ether or liquefied normally gaseous hydrocarbons such as ethane, propane or butane.  General naphthenic solvents used are nitrobenzene, nitrotoluene benzaldehyde, or pyridine; these solvents dissolve all the naphthenic constituents as distinct from limited solvents such as sulphur dioxide, furfural or aniline which dissolve only asphaltic and aromatic substances.  The latter solvents may be used in admixture with the general naphthenic solvents in the treatment of asphaltic base oils.  Preferably the two counter-flowing solvents used have boiling ranges which do not overlap.  A Californian crude oil, or lubricating oil distillate therefrom, is admitted to the centre of an extraction column through which propane and nitrobenzene flow in counter current.  Extraction is effected under pressure and at a temperature of about 4 DEG  C. at which the solvents are substantially immiscible.  If desired two extraction towers maintained at different temperatures may be employed.  The paraffinic extract is drawn off, and the solvent removed by evaporation under reduced pressure, leaving a paraffinic oil suitable for use as lubricating oil.  The naphthenic oil is obtained in a similar manner.  The oil may be dewaxed, and further treated with sulphuric acid and clay.  The deposition of wax during the extraction process may be prevented by adding a proportion of the oil obtained by the extraction process.  Other suitable combinations of solvents are: propane, together with one of the following: benzaldehyde, nitro toluene, pyridine, or nitrobenzene containing sulphur dioxide.

Title: Solubilization of lanolin
IPC: A61Q19/00
Filed: 1958-06-24
Abstract: A clear aqueous dispersion of solubilised lanoline is made by intimately mixing the lanoline with a higher fatty acid alkylolamide the acyl group having 8 to 18 carbon atoms, and the alkylol group or groups having up to 5 carbon atoms, and dissolving the mixture in water.  Preferably a surface active agent is added to the lanoline/alkylolamide mixture to assist solution in water.  The alkylolamide is made by condensing a higher fatty acid with preferably a lower dialkylolamine, e.g. diethanolamine.  The product contains about 60% of the amide and includes minor proportions of soaps, ester amides etc., which may be left in, and act as the surface active agent.  As separate surface active agents these may be used, ionic or non-ionic detergents, e.g. alkyl aryl sulphonates, sulphuric esters of polyhydric alcohols, fatty acid esters of alkylol sulphonic acids, fatty acid amides of amino alkyl sulphonic acids, the corresponding water-soluble soaps including salts of alkali metals, ammonia, or alkylolamines, and poloxyethylene ethers.  In examples, about equal parts of cocoanut diethanolamide and lanoline (or a higher proportion of the amide) are melted together at 180 DEG F. in a substabtially anhydrous state, to form a clear liquid, to which is then added sodium lauryl sulphate, and triethanolamine dodecyl benzene sulphonate, and the mixture stirred for 90 mins. with water.  The liquid produced is then filtered.  The cocoanut oil compound may be replaced by other homologues, e.g. lauroyl di-iso-pro-panolamide.  Other ingredients which may be present include sodium phosphate, hexachlorophene, and also formalin as preservative.  The clear liquid produced may be used as a base for making shampoos, washing compositions, and like preparations.
