摘要： On décrit un procédé d'impression par gravure selon lequel une image est imprimée sur une feuille de papier, le procédé se caractérisant en ce que le papier utilisé comprend une couche de surface contenant un pigment pour couchage de papier, les surfaces du pigment ayant été modifiées par un agent de traitement comprenant une partie hydrophobe afin de leur conférer des caractéristiques hydrophobes ou à hydrophobie accrue. On décrit également une composition de couchage de papier servant à préparer un papier couché devant être utilisé dans un procédé d'impression par gravure.

摘要： A method and apparatus are disclosed for obtaining a measurement indicative of the aspect ratio of non-spherical particles in suspension. Conductivity of the suspension is measured for two different orientations of the particles between points (5,6) and the difference between the conductivities measured is used as an indication of the particle aspect ratio. The particle orientation will be aligned in one measurement and in the other may be aligned and transverse to the first orientation direction or random. Alternatively there may be a single aligned orientation but transversely directed conductivity measurements.

摘要： Apparatus for grinding particulate solid material in a substantially dry state, the apparatus comprising, means for introducing particulate solid material into a grinding chamber (4), a perforated base (8) of the grinding chamber (4) through which gas is introduced to provide an upward flow of gas passing through the particulate solid material and an impeller (42) rotating in the grinding chamber (4) to agitate the particulate solid material. The perforated base (8) has a central imperforate area (10) which causes the gas to pass preferentially through the region near the walls of the grinding chamber (4). In addition, a horizontal baffle plate (17) having a central opening (18) is positioned in the grinding chamber (4) at a height above the perforated base (8) which is not greater than one half of the transverse width of the grinding chamber (4). The horizontal baffle plate (17) is provided to prevent the bed of particulate solid material from extending upwards to an undesirable degree near the walls of the grinding chamber (4). The grinding apparatus may be used with advantage in surface treating an inorganic material.

摘要： Material is comminuted in a substantially dry state in a chamber (4) as a result of agitation by a rotor. During the process, gas is admitted to the chamber (4) through a foraminous base (8) to flow upwardly in a uniform manner across the cross-section of the chamber. Pulses of gas are directed periodically at the material through inlets (15) to prevent agglomeration of the material. The pressure of the gas admitted through the inlets (15) is higher than that admitted through the foraminous base (8). Surface active agents may be added to the material, also to prevent agglomeration, as well as, or instead of the use of pulsed gas.
