摘要： A screen apparatus has a frame having a pair of spaced-apart longitudinal beams whose ends are bridged by a pair of spaced-apart transverse beams. A central longitudinal member or wall equidistant between the longitudinal beams has ends secured to the transverse beams. Transverse struts extend between the longitudinal beams and through the central wall and support a screen. The frame is mounted for limited displacement relative to a fixed support and a drive motor is fixed to the central member and carries an eccentric for limitedly displacing the frame and the screen in a vibratory or oscillatory manner.

摘要： The present invention relates to powder-layer three-dimensional printers (2) having a discrete supply hopper (340) and a recoater (20). The discrete supply hopper (340) is configured to transfer a build powder to the recoater (20) in a manner that enhances the uniformity of build powder layers that are dispensed from the recoater (20). In some embodiments, at least one of the discrete supply hopper and the powder hopper of the recoater is adapted to selectively contact the other, seal against the other, and/or have one partially inserted inside the other so as to diminish or prevent powder pluming during the transfer of build powder from the discrete supply hopper to the recoater.

摘要： A device, which serves to separate particles of a bulk material, which is deliverable at an input location and is removable processed in different or at least approximately unitary particle sizes at an output location, includes at least one separating element, which has a metal separating plate with through-openings provided therein, which separating element can be provided with ultrasonic energy and for this purpose is connected to an ultrasonic transducer and which is held by a holding device. The holding device is a mounting shaft, which is held at one end or at both ends fixedly or movably, in particular rotatably and/or axially displaceable, and which at one end or at both ends is connected to an ultrasonic transducer, by means of which ultrasonic energy is couplable via the mounting shaft into the separating element, which is designed to be dimensionally stable.

摘要： A machine and a method for treating cakes from additive manufacturing processes, wherein the cake contains residual powders and sintered pieces is disclosed. The machine includes a cylindrical vibrating body which is placed in a position above a vibratory finishing or tumbling or vibro-blasting machine and is separated from the vibratory finishing or tumbling or vibro-blasting machine by a remotely operable door and the cylindrical vibrating body obtains its vibration from the machine below. The machine includes means for destructuring the cake in order to obtain the separation of the non-sintered powder from the sintered pieces present in the cake and means for recovering the powder resulting from the destructuring of the cake.
