Title: Coating the bore of very long aluminium tubes - varnish pumped down bore followed by plunger which removes excess varnish
Inventor: PHILIPPE ROGER
IPC: B05D7/22
Filed: 1974-06-26
Abstract: Process for varnishing the bore of a very long Al or Al-alloy tube with a small dia. by passing varnish through the tube. The novelty is that, after injecting the varnish by a pump into the bore of the tube, the thickness of the coating is controlled and the excess varnish removed by the forced circulation in the bore of a plunger fitted with flexible or semi-rigid elements which are in contact with the varnish; the light solvents are then removed by passing compressed air downt he tube which is subsequently placed in an oven and hto-air pulled through the tube by suction to remove the rest of the solvents for recovery or disposal. The plunger is pref. a threaded rod on which flexible rings, e.g. of plastic are mounted; alternatively, a felt plunger can be used. Coating tubes 5-30 mm borer and several hundred metres long, e.g. for hot water radiators or compressed-air pipes, where the coating prevents corrosion. A uniform coating is obtd. over the entire bore without added cost w.r.t. known methods.

Title: Composite membrane and insulating panel for cryogenic tank - comprising a sheet metal membrane fixed to a glass fibre reinforced rigid foam core
IPC: F17C3/02
Filed: 1975-03-03
Abstract: In a system, tool assembly and method of construction permitting rapid and economic prodn. of cryogenic vessels for methane marine carriers and land storage reservoirs for cryogenic fluids, very long pre-fabricated panels are used consisting of a metallic cryogenic membrane and a rigid insulating wall which also acts as a secondary impermeable barrier, the assembly of which does not necessitate either conventional mechanical units or scaffolding. Advantageously, the rigid insulating wall consists of a plastic foam pre-stressed by glass fibres incorporated therein. The pre-fabricated panels do not require the mechanical fixing elements used in conventional membrane cryogenic vessels, while the adhesive used is spread out as parallel ribbons. The cost of the vessel is thus minimised and assembly is rapid and reliable, partic. since the secondary barrier has triple sealing, over and above that of the metallic cryogenic membrane. More specifically, the composite panels comprise a thin sheet metal cryogenic strip, fabricated from "Invar" (RTM) or alpha-type titanium, fixed to a support layer of rigid foam e.g. polyurethane or polyvinyl chloride, with open cell structure and reinforced by glass fibres enclosed between upper and lower layers of glass fibre fabric coated with polyurethane.
