@ An air classifier system for classifying bed particles includes a drop tube (9) leading from a reaction chamber (2) and communicating with a discharge tube (12) in which is located a gas ejector (16). The classifier (18) in which air is used as an aerodynamic sieve to entrain particles of an acceptable size for return through the conduit (14) to the bed (4). Oversize particles descend through the classifier (18) for discharge into a receptacle (28).

This invention relates to a catalyst for usin the direct conversion of synythesis gas to olefinic hydrocarbons in good yield. tt also relates to a process for producing the catalyst. The catalyst comprises a highly porous amorphous silica support on which is deposited one or more monolayers of silica. The catalyst is then impregnated with a transition metal. The monolayer of silica is formed by the hydrolysis of a compound such as ethyl orthosilicate while it adsorbed onto the support.

Solid fuel combustion equipment in the form of a grate assembly comprises longitudinally extending support elements 6 on which are mounted laterally orientated grate bars (10). The support elements (6) are pivotable about their horizontal axes and are provided with sealing means (14) at their adjacent margins to effect a seal to prevent in use passage of air when the elements (6) are horizontally aligned. De-ashing of the grate assembly in use is achieved by tipping the support elements (6), whereupon ash falls to a receiving are (11) whence it is removed.

he present invention relates to varnishes for use in the preparation of glasscloth laminates, methods of their production and laminates made therefrom. The varnish is made by dissolving 100 parts of a TFP resin having a number average molecular weight of about 1000 and an oxygen content of about 8% in 60 to 65 parts of butan-2-one or isopropanol. 8 to 12 parts of hexamine are dissolved in a minimum quantity of a solvent comprising water and IMS in a ratio of about 3 : 5. The two solutions are thoroughly mixed and filtered to produce the varnish. The varnish is used to prepare glasscloth laminates for use as printed circuit boards.
摘要:
A feed device (1) for solid fuel domestic appliances comprises a hopper (2) with downwardly inclined sides (3) defining a discharge slot (4) beneath which is located a flat plate (6) in spaced relation thereto. The plate (6) is mounted on a central pivot (7) and is movable thereabout by a suitable low power low speed drive (5). A spreader device comprising two series of inclined spaced apart metal strips (8) is located below the plate (6). Fuel held within the hopper (2) flows out onto the plate (6) and assumes a natural angle of repose when the plate (6) is horizontal. Upon small angular movement of the plate (6), fuel is caused to flow off the plate (6) which in use is disposed evenly over a fire bed by the spreader device.
