An apparatus having an adjustable ambient air-oxygen blender that adjustably mixes ambient air with an oxygen supply, especially where a size, diameter or flow rate of an orifice is mechanically adjustable so as to control a quantitative mixing function of the blender.

A method of making a component of an electrical machine is provided. An additive manufacturing process is used to manufacture a part, including applying beams of energy to a successive plurality of ferromagnetic material particles and fusing them together to form a ring or segment of a ring with an axis, a solid portion, and laminas that extend from the solid portion in a radial or axial direction.

The present disclosure provides three-dimensional (3D) printing methods, apparatuses, systems and/or software to form one or more 3D objects, some of which may be complex. In some embodiments, the one or more 3D objects comprise an overhang portion, such as a ledge or ceiling of a cavity. The methodologies may be used to form overhang portions with diminished deformation, defects and/or auxiliary support structures.

The present disclosure generally relates to methods for additive manufacturing (AM) for fabricating multi-walled structures. A multi-walled structure includes a first wall having a first surface and a second wall having a second surface facing the first surface to define a passage having a width between the first surface and the second surface in a first direction. The multi-walled structure also includes an enlarged powder removal feature connecting the first wall and the second wall. The enlarged powder removal feature has an inner dimension greater than the width in the first direction and at least one open end in a direction transverse to the first width.

The invention relates to a method for producing a calibrated combination (I) of parts. The combination (I) of parts comprises at least one first part (2) with a first contact surface (3) and a second part (4) with a second contact surface (5), wherein the parts (2, 4) contact each other via the contact surfaces (3, 5) in the combination (I) of parts; and the parts (2, 4) are designed to be free of an undercut at least with respect to an axial direction (6) and can be moved relative to each other along the axial direction (6) and thereby along the contact surfaces (3, 5) in the calibrated combination (I) of parts. The method has at least the following steps: a) providing the parts (2, 4) in the form of green bodies (7, 8), b) sintering the parts (2, 4) and at least forming bonded connections between the parts (2, 4); c) arranging the combination (I) of parts in a calibrating tool (IO); d) moving the parts (2, 4) relative to each other; e) arranging the parts (2, 4) in order to form the combination (I) of parts; and f) calibrating the combination (I) of parts.

The invention relates to a method for producing a sintered component comprising the steps: providing a metallic powder; filling the powder into a powder press; pressing the powder to form a green compact; removing the green compact from the powder press; sintering the green compact into a sintered component with pores; optional redensification of the sintered component; hardening of the sintered component, wherein the pores of the sintered component, prior to hardening at least in that region of the surface of the sintered component which is subjected to a hardening, are at least partially filled with a filling agent.

A method and device for manufacturing a bevelled stone, particularly for a timepiece are disclosed. A precursor is produced from a mixture of at least one material in powder form with a binder. The method includes pressing the precursor so as to form a green body, using a top die and a bottom die comprising a protruding rib, sintering the green body so as to form a body of the future stone in at least one material, the body including a peripheral face and a bottom face provided with a groove, and machining the body including a substep of planning the peripheral face up to the groove, such that an inner wall of the groove forms at least a flared part of the peripheral face of the stone.

An implant for the stabilization of bones or vertebrae is provided, the implant being a solid body including a longitudinal axis that defines a longitudinal direction and including a flexible section that has a surface and has a length in the longitudinal direction, the flexible section including at least one cavity located near the surface and having a width in the longitudinal direction that is smaller than the length of the flexible section, the at least one cavity being connected to the surface through at least one slit, and a width of the slit in the longitudinal direction being smaller than the width of the cavity.

The instant invention includes a multiple-Venturi nozzle and a system, method of manufacture and method of using same. The instant multiple-Venturi nozzle has a generally cylindrical body with a generally flat bottom surface and a generally flat distal outer surface and a generally arcuate vertical surface parallel to the bottom and outer surfaces. The instant multiple-Venturi nozzle further includes a plurality of chokes generally perpendicular to the bottom and outer surfaces, each of said chokes extending through the body and having a choke inlet and a choke outlet. The instant multiple-Venturi nozzle further includes a manifold extending from the outer surface partially into the body and a plurality of manifold channels connecting the manifold to each choke, each of said manifold channels being generally perpendicular to a corresponding choke, having a manifold outlet and a distal manifold inlet and being offset in a helical distribution from other manifold outlets corresponding to the same choke.
