Abstract: The present invention relates to a method for producing a powdered porous product from at least one starting powdery and/or viscous product, characterised in that it comprises the continuous following steps without exposing the product to open air: a) preparing the starting product in order to make it viscous; b) in a thermo-mechanical machine (10) for continuously realising transport and/or mixing functions of viscous products or dry-material rich products, lowering the viscosity of the viscous product without changing its dry-material content, by intimate mixing with a gas injected into the processing machine (10) and simultaneously initiating the porosity in the viscous product; c) continuously with the processing machine (10), statically or dynamically intensifying the intimate mixture of the viscous product with a gas in order to obtain an aerated and porous mass; and d), dividing said mass in order to obtain aerated and porous particles.

Abstract: In the disclosed method, in order to control an extruder including two intermeshing screws for driving a material to be extruded, the following steps are performed while a material to be extruded is being processed by the extruder: constantly measuring the viscosity of the material in the flow of the material in the extruder, and adjusting the extruder in accordance with the viscosity measurement. In order to adjust the extruder in an effective and efficient manner, the rate at which the extruder is filled with material along the intermeshing screws is modified by adjusting, downstream from the screws, a flow cross-section for the material in accordance with the viscosity measurement.

Abstract: The invention relates to a method for the continuous production of a powdered product from a product in the liquid state in the form of a solution-, suspension- or emulsion-type mixture in an aqueous medium. According to the invention, during the first step (E1) of the method, the product in the liquid state is transformed into a product in the viscous state. The invention is characterised in that it includes at least one overrun step (E2, E4) and at least one product-drying step (E3, E6) comprising at least a first step (E3) involving thermomechanical treatment with at last one thermomechanical treatment machine into which the viscous state product and a determined amount of powered product from the same family as the liquid state product are injected simultaneously. The treatment machine is configured to mix the viscous state product and the powdered product such as to produce solidified particles of the product upon contact with the ambient air.

Abstract: A two layer material, and method for its manufacture, are disclosed, including an inner and an outer layer, the inner layer formed from an aliphatic urethane elastomeric composition as the layer exposed to view and to the environment and an aromatic urethane elastomer as the inner or backing layer. The layered material may be used to form a skin layer in an automotive air bag door. The layer material may be double cast from microspheres. The inner layer may be formulated to have good heat stability and flexibility, yet not include additives such as UV stabilizer as it may be positioned behind the outer protective layer.

Abstract: Method for sizing the cells of a centrifugal liquid-liquid chromatography “column” (CPC column) consisting of stacked discs on which the cells connected in cascade (in series) by small channels are engraved. Rotation of the stack creates a high centrifugal acceleration field which makes it possible to keep a liquid phase referred to as stationary phase motionless, whereas a mobile phase circulates along the CPC column. The cells are three-dimensional, with two dimensions (L, l) of the cells oriented in a plane substantially normal to the axis of rotation (?) of the disc and a third dimension (e) oriented in a direction substantially parallel to the axis of rotation, and selected so as to be at least equal to one of the other two dimensions (L, l), thus providing higher efficiency. When the scale of the devices has to be changed, the size of the cells is modified ensuring that, in any case, this third dimension (e) is favored so as to be as great as possible.
