Title: Agglomeration and treatment of iron oxide fines
IPC: C22B1/24
Filed: 1971-04-20
Abstract: Method of obtaining hard agglomerates from fine iron oxide fines consists of (a) passing fines through agglomerating rollers (smooth or tarred), (b) charging agglomerate with particle size >8 mm into fluidised bed furnace and, (c) treating at >800 degrees to 900 degrees C in light or heavy oxidising atmosphere using either liquid or gaseous combustible, or hot air. The hot spent gas from the fluidised bed may be used for preheating the incoming air, and precipitated fines may be passed back to the agglomerating rollers. By the use of low O2 partial pressure in the furnace Fe2O3 may be converted to Fe3O4. Method produces agglomerate suitable for dry transportation and for further pyrometallurgical treatment.

Title: Negative ion generator for air conditioning - has multiplier for ions generated by alpha particles source
Inventor: BRIFFAUD BERNARD
IPC: H01T23/00
Filed: 1974-12-27
Abstract: Negative ion generator intended to provide a high yield, low ozone content, flow of air for general air conditioning purposes. The primary source of the ions is a high energy alpha particle source (6), possibly polonium 210. Amplification of ions generated is by multiplication due to acceleration through a high potential gradient, created by electrodes (8, 9) downstream of the source. Further electrodes may provide acceleration of the ions so generated towards the output end of the cylinder housing the generator. Ozone created in the process is removed by causing compression of the gas through a Venturi type throat (14). Filtered air is driven through the system by a fan (3).

Title: Surface colouration of particulate thermoplastic - using binder comprising soft and hard resins dissolved in colouring system
IPC: B01F33/40
Filed: 1975-07-11
Abstract: A particulate thermoplastic is coloured by treating it with a suspension or soln. of a colourant in an inert solvent in which a binder is dissolved. During or after the treatment the solvent evaporates and the thermoplastic particles become coated with the binder in which the colourant is dispersed. The binder is a combination of a soft and wetting resin and a hard resin, both resins being thermally stable and soluble in the solvent. The resin combination in the binder allows a wider variety of thermoplastics to be coloured and he concn. of the colourant to be increased so that masterbatches can be prepd. The binder coating also improves the mechanical strength and thermal stability of the thermoplastic material as well as other props. e.g. impermeability to fluids, thermosealing characteristics, etc.
