A heating apparatus for heating an object having a cylindrical outer peripheral surface includes: a support member for supporting the object to be heated; a covering member movable in the vertical directions relative to the support member and having inner wall surfaces with an open lower end, the inner wall surfaces defining an accommodation space for accommodating the object to be heated; the covering member closing the accommodation space when the covering member is disposed on the support member; the covering member allowing loading or unloading of the object to be heated when the covering member is separated from the support member; and a plurality of ring-shaped light sources each provided to surround the cylindrical outer peripheral surface of the object to be heated and arranged in the vertical direction in the accommodation space and radiating light for heating the object to be heated.

Embodiments of the present disclosure describe a magnetic substrate including a cured magnetic ink and a cured polymer resin, wherein the cured magnetic ink includes a plurality of functionalized magnetic iron oxide nanoparticles and wherein the magnetic substrate is a freestanding magnetic substrate.

A method for welding at least two parts including a thermoplastic material and having respective surfaces to be welded, including: inserting an insert between the surfaces to be welded of the two parts; generating heat via the insert; wherein the insert moves in relation to the parts to be welded in a welding direction. Also, an installation adapted for implementation of this method.

Extracorporeal circuit devices can be used for on-pump open-heart surgery to support surgical procedures such as coronary artery bypass grafting. In some cases, a centrifugal pump is used as part of an extracorporeal circuit. Centrifugal pump heads are described herein that induce flow on two sides of an impeller plate, and that can be conveniently mechanically assembled.

A system for retaining a magnet in a cochlear implant, comprising a retainer embedded within an encapsulant of the cochlear implant, and a magnet case engaged with the retainer. A retainer for retaining a magnet within a cochlear implant comprising a number of first fasteners that couple with a number of corresponding second fasteners of a magnet case hermetically sealing the magnet, and a number of supports embedded within an encapsulant of the cochlear implant.

An interlocking toy building block includes a first block body and a first magnet positioned therein a first distance from a first outer surface thereof to provide a first predetermined magnetic polarity to the first outer surface. When the first outer surface is brought into close proximity with a second outer surface of a second block body having a second magnet positioned a second distance therein and exhibiting a second predetermined magnetic polarity opposing the first predetermined magnetic polarity, the first outer surface is configured to mate with the second outer surface in an interlocking position. A potential magnetic force F.sub.m between the pair of magnets is determined by the formulation: F.sub.m=F.sub.o e.sup.−rd where F.sub.o is the initial force (i.e., no separation distance between magnets), and e.sup.−rd is the exponential function of the rate of decay “r” of the magnets and the distance “d” between the magnets.

A mold apparatus for forming a molded part includes a mold body, a mold cavity formed in said mold body, a plurality of valve gates associated with said mold body, and a controller in communication with said plurality of valve gates. The controller is programmed to time opening of each valve gate based on a selected flow rate required to eliminate weld lines in the product.

An improved RPG shield netting that comprises a net structure supporting a spaced arrangement of one-piece nodes manufactured using an insert injection molding process such that each node is formed as a one-piece three-dimensional solid shape with uniform surfaces that envelopes a portion of one or more cord elements.

A method of fabricating a blade. The blade comprises subassemblies made of thermoplastic composite materials, each subassembly comprising an internal arrangement and at least one external arrangement, each internal arrangement comprising a stack of intermediate layers comprising reinforcing fibers impregnated with a semicrystalline thermoplastic matrix, each external arrangement comprising at least one surface layer comprising reinforcing fibers impregnated with an alloy of a semicrystalline thermoplastic polymer and of an amorphous thermoplastic polymer. An assembly film comprising an amorphous thermoplastic material and a ferromagnetic member is interposed between two surface layers of two distinct subassemblies that are to be assembled together by a method of local heating by induction.

An ejector element with a trigger for a belt buckle sensor includes a plate-shaped ejector body and a trigger blade of a magnetic and/or metallic material for producing a change in a magnetic field of a Hall sensor or an inductive sensor. The ejector element is distinguished by the fact that the trigger blade is connected in one piece to the ejector body, wherein the one-piece connection between the trigger blade and the ejector body is produced by an injection-molding process.
