Title: Improvements in or relating to the protection of aluminium and its alloys against corrosion
IPC: C23F11/10
Filed: 1955-02-16
Abstract: A method of preventing or minimizing corrosion or corrosion and rubbing on aluminium or aluminium alloy surfaces comprises applying to the surface, either simultaneously or separately, substances that together form a penetrated monolayer 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 surfaces, which may be anodized, are treated with the sensitizer, examples of which are aryl or alkyl sulphates, sulphonates, phosphates, or phosphonates or salts of fatty acids, and the second compound is an alkyl or aryl alcohol, or cholesterol. The compounds may be applied to the surface simultaneously as an oil-water emulsion, e.g. sodium dodecyl sulphate in water and cholesterol in B.P. paraffin, or separately by successive treatments e.g. with a solution of lanoline in white spirit of B.P. paraffin and sodium alkyl sulphonate in water. The surface may be stoved at 120 DEG F. between the lanoline and sulphonate treatments. Various combinations of pairs of the above compounds are described with various degrees of heating between 74 DEG F. and 80 DEG C. A specific sensitizer mentioned is sodium lauryl sulphate in water.

Title: Electronic braking system
IPC: B60T8/66
Filed: 1972-06-17
Abstract: The invention relates to an electronic anti-skid system which avoids the untimely operating of the system which occurs especially further to the aleatory variations of the wheel speed. A given percentage of the output voltage of a wheel speed sensor is memorized in a capacitor by means of a diode, as soon as the wheel decelerates. The exhaust signal which is given at the output of an anti-skid logic circuitry is transmitted to a transistor only when the wheel speed has decreased of an amount equal to the complementary percentage of the given percentage. The resetting of the devices is effected by another diode which deletes the memorized voltage of the capacitor.
