Title: Protective coatings of polyethylene
IPC: B05D7/14
Filed: 1965-09-27
Abstract: Infusible protective coatings on metal components are produced by forming a fluidized bed of a mixture of uncross-linked polyethylene and an organic peroxide, immersing the metal component in the bed to form a sintered coating on the metal component under conditions such that no significant cross-linking occurs, removing the component from the fluidized bed and subjecting it to heat to cause cross-linking of the polyethylene. The peroxide, which may be incorporated by milling or by the use of a solvent, may be benzoyl peroxide, cumene hydroperoxide, p-menthane hydroperoxide, pinane hydroperoxide, dicumyl peroxide or a ,a 1-bis - t. - butylperoxy - di - isopropylbenzene. In examples iron strips are coated with (1) high-pressure and (2) low-pressure polyethylene in which cross-linking is effected with dicumyl peroxide.ALSO:A method of producing infusible protective coatings of cross-linked polyethylene on metal components comprises the steps of forming a fluidised bed of a mixture of uncross-linked polyethylene and an organic peroxide, immersing the metal component in the bed to form a sintered coating on the metal component under conditions such that no significant cross-linking occurs, removing the component from the fluidised bed and subjecting it to heat to cause cross-linking of the polyethylene. Specified peroxides are benzoyl and dicumyl peroxides; cumene, p-menthane and pinane hydroperoxides; and a ,a \sv-bis-t-butylperoxy diisopropylbenzene.  The metal component may be pretreated, e.g. by sand blasting, and at 150 to 250 DEG C. immersed in the fluidised bed for a few seconds.  Heat treatment of the resulting coating may be effected at 140 to 250 DEG C for a few minutes.  In examples (1) high pressure and (2) low pressure polyethylenes are applied to sand blasted iron strips using dicumyl peroxide as the organic peroxide.

Abstract: 1475474 Mixing fluent materials CONTINENTAL OIL CO 9 Oct 1975 41479/75 Heading B1C [Also in Division Fl] Apparatus for making and transporting a slurry (e.g. of coal in water) comprises a sump 14, Fig. 1 to which particulate solids and carrier liquid are supplied, the level in the sump being maintained constant by a sensor 29 and controller 31 which control the liquid supply rate. Thus a diminution of supply of solids is made up by an increase in carrier liquid, and vice versa, so that the rate of formation of slurry, albeit of varying concentration, is constant. In the embodiment of Fig. 2 the controller 26 is replaced by a controller and comparator 74 which receives signals from flowmeters 72, 59 respectively representative of the slurry flow rate and the carrier liquid supply rate and deduces the concentration of solids in the slurry, which is compared with a pre-set desired value. An increase, for example, in solids concentration will cause the controller 74 to increase the pumping rate of pump 68; this will cause the level in the sump 52 to fall, whereupon the controller 60 will increase the carrier liquid flow to reduce the solids concentration. The controller 74 also controls the flow of solids from the hopper 42 to the crusher 44.
