Abstract: 1363627 Coated steel BRITISH LEYLAND TRUCK & BUS DIVISION Ltd 20 Oct 1971 [3 Nov 1970] 52702/70 Heading B2E  An anti-corrosion treatment process comprises the steps of (a) galvanising a steel member to give the member a zinc coating, (b) treating the galvanised steel member with a phosphate solution to create a coating of zinc phosphate on the zinc coating, and (c) applying a powder coating to the zinc phosphate coating. The steel member may be galvanised either by hot-dip galvanising or electro-galvanising. The posphating step may be carried out in a phosphate plant which consists of a first water rinse, a second water rinse, a zinc phosphate treatment, a third water rinse, a chromate rinse and finally a drying oven. The powder coating may comprise an epoxy powder which is then stoved at 150-200‹C., or an acrylic or alkyd resin and may be applied electrostatically or by a fluidised bed process. The steel member may be fabricated steel sub-assemblies and rivets which are used to construct ex service vehicle bodies. The zinc coated member may be treated with a protective resin or lanolin compound to enable it to be transported and stored, the protective resin or lanolin compound being removed prior to the phosphating stage. After the protective coating is removed the member may be de-greased in a trichloroethylene vapour degreaser. A conventional bituminous underseal may be applied to those sub-assemblies which form part of the understructure of the vehicle body and those sub-assemblies which include box-sections can also be sprayed with an oil-resin mixture.

Abstract: 1285885 Measuring scattered light photoelectrically UNITED KINGDOM ATOMIC ENERGY AUTHORITY 10 Oct 1969 [7 Nov 1968] 52906/68 Heading G1A In a device for measuring light scattered from suspended particles in a fluid 25 and having a lightsource 13, e.g. a xenon flash lamp with a diffusing screen 14, and a photo-detector 12, e.g. a photo-multiplier, a switchable means 22 provides alternately a reference light path 32 and a path 26 for scattered light, the output of the detector during successive reference periods being maintained constant by a control means, Fig.2 (not shown) which adjusts the sensitivity of the detector 12 and/or the intensity of the source 13. The switchable means 22 is an apertured rotatable disc, and the light-source is arranged to pulse only when either the reference path 32 or measuring path 26 is unobscured by the disc. The detector output is fed to an analogue-to-digital converter (33), and during reference periods the ADC output is supplied to a ratemeter (43) and then to a comparator (44) where it is compared with a reference voltage, any resulting error signal being arranged to control the HT voltage to the photo-multiplier. The error signal may also be used to control the discharge voltage of the source 13. A circuit is described, Fig.3 (not shown) for stabilizing the mains supply voltage to the xenon discharge tube. The amount of light scattered from the fluid, which may be an atmospheric sample, and hence its visibility, is determined by summing the number of pulses generated by the ADC during a number of measuring periods to give the average visibility during those periods. Alternatively, a log ratemeter (42) may be provided to give an analogue output representative of the visibility, and this output may be arranged to switch on fog lamps at a certain level of visibility .
