摘要： A kneading apparatus for a thermoplastic resin, includes: a plasticizing cylinder which has a high pressure kneading zone and a pressure reduction zone; a screw in the plasticizing cylinder; a downstream side seal mechanism which shuts off communication between the high pressure kneading zone and the pressure reduction zone; and a pressure reduction zone pressure adjusting mechanism which is connected to the pressure reduction zone and which controls a pressure of the pressure reduction zone so that the pressure is not less than an atmospheric pressure and the pressure is not more than a maximum pressure of the high pressure kneading zone that is achieved when kneading a molten resin with a pressurized fluid, when the downstream side seal mechanism shuts off the communication between the high pressure kneading zone and the pressure reduction zone.

摘要： Extrusion of a mix containing a pharmaceutically active agent can be achieved using a plasticising excipient in an amount sufficient to act as plasticiser and also act as lubricant, thereby avoiding the need for inclusion of a lubricant. The invention provides multiparticulates with controlled release properties, substantially free of lubricant. The present invention is preferably directed to extruded multiparticulates containing an opioid such as oxycodone, an ammonium methacrylate copolymer such as Eudragit® RSPO, a plasticising excipient such as preferably stearyl alcohol and a water permeability modifier such as preferably Eudragit® RLPO. The obtained multiparticulates show a release rate profile which is pH-independent.

摘要： An extruder for welding plastic components, comprising a front part for plasticizing and ejecting additional plastic welding material, and a rear part, for feeding and breaking up a continuous filament made of the additional plastic material. The rear part comprises a feed channel that cooperates with a worm screw for the advancement of the filament. The feed channel is delimited by the thread of the worm screw on one side and by a sliding surface for the filament on the opposite side. The distance between the sliding surface and the crest of the thread decreases in the direction in which the filament is fed, in order to provide scoring of increasing depth on the filament. The thread comprises at least one discontinuity of the worm that has a sharp discontinuity end for cropping the filament at the scoring.

摘要： A method is disclosed for casting a concrete product, in which method the concrete product is cast in an essentially horizontal slipform casting process during which the top surface height and profile of the concrete product being cast is measured continually. Based on the measurement results, the relative proportion of the concrete mix flowing to the upper layer or lower layer of the concrete product is controlled by way of moving or tilting a feed trough (12) located below the concrete mix feed means (2).

摘要： We have determined that strength characteristics of elastic strand improve when the strand is heated. Thus, the present invention is directed to improving strength characteristics of an elastic strand by heating the strand. The strand may be heated by thermal conduction and/or convection, by irradiative methods using, for example, infrared or microwave radiation, or some combination of these. If the elastic strand is made at a location different from the location where the strand is used as a raw material, the strand may be heated at either location, or both locations. Furthermore, the strand may be heated in-line, i.e. as part of the process that makes the strand or the process that uses the strand as a raw material, or off-line, i.e. in a step separate from either of the aforementioned processes. Finally, in addition to heat treating the strand, the strand's exposure to water or water vapor may be regulated to reduce or eliminate strength degradation.

摘要： An apparatus for extracting screw elements from a screw shaft comprises a frame, a stationary clamp mounted on the frame and disposable between open and closed positions, a carriage mounted on the frame for motion toward and away from the stationary clamp, a movable clamp mounted on the carriage for motion therewith and disposable between open and closed positions, a first drive coupled to the stationary clamp for opening and closing the stationary clamp, a second drive coupled to the movable clamp for opening and closing the movable clamp, and a third drive coupled to the carriage for causing motion of the carriage toward and away from the stationary clamp, wherein clamping of a downstream screw element by the stationary clamp, clamping of an upstream screw element by the movable clamp and one or more strokes of the carriage away from the stationary clamp result in removal of the downstream screw element held in place by the stationary clamp from the screw shaft. The procedure is repeated until all the remaining screw elements are removed.
