Abstract: An inner drive for a magnetic drive pump includes a magnet supported on a yoke. The inner drive is driven about an axis to pump a corrosive process fluid. The magnet and yoke are fully encapsulated during the molding process to completely surround the magnet and yoke in a protective plastic shell. A sleeve is arranged radially outwardly of the magnet to provide further protection. Backing rings are arranged on either side of the magnet. A bonding material joins the plastic shell to the backing rings and sleeve to prevent a space from forming beneath the plastic shell that would become filled with the process fluid once it has permeated the plastic shell. A protective coating is arranged on at least a portion of the magnet to further insulate the magnet from the process fluid.

Abstract: A spool assembly comprising a housing structure, a spool rotatably retained in an interior region of the housing structure, and a sealed sheath encasing the housing structure to define a barrier for the encased housing structure and the rotatably retained spool. The spool assembly further comprises a locking arm disposed outside of the sealed sheath and configured to operably engage the spool through the sealed sheath and through the housing structure in a manner that does not penetrate the sealed sheath, where the locking arm prevents the spool from rotating relative to the housing mechanism when operably engaged with the spool. The locking arm may disengage from the spool in a hands-free manner when the spool assembly is loaded into a bay of an additive manufacturing system.

Abstract: A system for producing a tangible object. The system has a space which can be filled with a fluid. A reference platform at least partially defines at least one side of the space. The system further has a phase-transformer which can form a layer of the object by selectively transforming the fluid into a solid in a predetermined area of the space. An actuator can separate the layer from the reference platform by moving the layer relative to the reference platform or vice versa. The system has a controller connected with an actuator control output to the actuator and/or with a transformer control output to the phase transformer. The controller can control the production of the object based on a determined value of the force exerted on the reference platform or the solid or of a parameter related to the force.

Abstract: A process for the production of an aircraft panel made of double-curved composite material, with the panel being obtained from a three-dimensional preform that includes fibers that are distributed in a defined arrangement, includes manufacturing a flat fiber preform (22), and deforming the flat preform (22) in such a way as to produce the three-dimensional preform, with the fibers following suitable trajectories at the flat preform in such a way as to obtain the defined arrangement of the fibers after deformation.

Abstract: A method including the steps of forming an inner ring of a wheel hub, by joining a spindle and an insert ring fitted onto the spindle, on a side of a first end of the spindle; axially blocking the insert ring on the spindle by plastically deforming the first end of the spindle that forms an upset collar therewith, which axially protrudes from the insert ring; frontally obtaining on the collar, on the side opposite to the insert ring, a frontal toothing by means of a single creator tool, towards the collar, with a toothing complementary to that to be obtained, by axially impressing onto the collar, in sequence, one or more teeth of the complementary toothing by eccentrically pushing the creator tool against the collar while the creator tool is held substantially coaxial to the wheel hub, thus acting peripherally in sequence on the whole creator tool.

Abstract: An agitating feeder is provided in a compression molding machine that includes at least one die having a die bore, an upper punch and a lower punch retained respectively above and below the die so as to be vertically slidable, and a compression mechanism for compressing and molding a powdery material filled in the die bore by the upper punch and the lower punch. The agitating feeder includes an agitating rotor for rotating to agitate the powdery material, a housing accommodating the agitating rotor, and a gas flow device for flowing gas in the housing.

Abstract: Provided is a method for manufacturing a gear wheel, the method including: preparing an insertion unit formed of a steel material having a hollow pipe shape; injection-molding an outer side unit including teeth on an outer circumference; and molding a connection unit having a wheel shape by injecting resin into at least three points between the insertion unit and the outer side unit so as to connect the insertion unit and the outer side unit after arranging the insertion unit on the inner center of the outer side unit. According to the method, removing of an unnecessarily injected portion may be omitted since the resin is injected between the insertion unit and the outer side unit while injection-molding the connection unit. Also, productivity is increased by decreasing a number of defective products generated due to cracks.
