A respiratory protection composite facepiece is disclosed and includes a polymeric rigid facepiece body portion having a first surface and a second surface and a silicone sealing facepiece element chemically bonded at least one of the first surface or the second surface. The first and second surfaces can be opposing major surfaces. A second silicone element is chemically bonded to at least one of the first surface or the second surface. Methods of making the same are also disclosed.

Manufacturing methods are described for a goggle having an outrigger system where each outrigger includes a first segment coupled to a second segment at a fixed joint. Portions of the first segment may interlock or join with complementary portions of the second segment, such as through interlocking shapes, a solid friction lock, or via co-molding. The joining portions of the first and second segments may include complementary shapes that interlock together to secure the first and second segments together. The second segment may be molded onto or around at least a portion of the first segment, or vice versa, to secure the first and second segments together.

A biochip for the integration of all steps in a complex process from the insertion of a sample to the generation of a result, performed without operator intervention includes microfluidic and macrofluidic features that are acted on by instrument subsystems in a series of scripted processing steps. Methods for fabricating these complex biochips of high feature density by injection molding are also provided.

A material dispense tip includes an elongated hole in an elongated neck that extends from an input end of the neck to an output end of the neck. The hole at the output end of the neck has a first diameter. The output end of the neck is positioned against a die surface. A punch is inserted into the hole at the input end of the neck. An external force is applied to the neck to cause the output end of the neck to be deformed under compression by the die surface, to reduce the diameter of the hole at the output end of the neck from the first diameter to a second diameter that is less than the first diameter.

Embodiments of the present disclosure may include a method including assembling at least two building elements together. Embodiments may also include applying a stimulus to at least one of the at least two building elements, the stimulus being capable of changing a color of at least a portion of the one of the at least two building elements. In some embodiments, the at least two building elements may be assembled together prior to applying the stimulus.

An article of headgear that has a head-covering article, a lens moveably attached to the head-covering article, and a seal attached to the lens, the seal comprising a first polymeric material and a second polymeric material, the first polymeric material having a greater tensile modulus than the second material. In an exemplary embodiment, the lens is moveable from a first, lowered position to a second, raised position, and when in the first, lowered position, the seal sealingly engages the head-covering article. In some embodiments, the tensile modulus of the first polymeric material is at least about 5× greater or even about 10× greater than the tensile modulus of the second material.

The invention generally relates to methods for manufacturing components for use in a device for generating substantially planar micrografts. The methods of the invention provide for the manufacture of substantially uniform components for a cutter contained within the device, the cutter configured to cut a blister in order to produce a substantially planar graft.

A handle for a tool is provided that is formed of a core positioned within a sleeve of a temperature resistant material to form a handle with a space between the core and the sleeve. The core can be formed by machining a metal material while the sleeve and an optional skin positioned on the sleeve can be molded. The materials forming the sleeve and skin, and the space formed between the core and sleeve, create a handle that can be adapted to form a variety of different tools with different mechanisms located in the core that also has improved heat transfer characteristics for sterilization purposes.

Embodiments of golf club heads with apertures and methods to manufacture golf club heads are generally described herein. In some embodiments, a golf club head comprises a face portion, a back portion generally opposite the face portion, a heel portion extending between the face portion and the back portion, a toe portion opposite the heel portion and extending between the face portion and the back portion, and a crown portion extending between the face portion, the back portion, the heel portion, and the toe portion, the crown portion comprising a plurality of crown aperture. The crown portion comprises a first region and a second region, wherein the first region is nearer to the face portion than the second region, the first region and the second region are separated by a bell-shaped curve. The bell-shaped curve is located a distance D1 from the face portion and the second region comprises a recess portion. The plurality of crown apertures is defined within the recessed portion. In some embodiments, the golf club head comprises both metal and fiber-based composite portions. In other embodiments, the golf club head comprises a plurality of sole apertures. Other embodiments may be described and claimed.

A method protects a field joint of a pipeline, where chamfered edges of thermally-insulating parent coatings on conjoined pipe lengths are in mutual opposition about a longitudinally-extending gap. The method includes manufacturing an hourglass-shaped inner layer around the pipe lengths, which layer may be moulded. The inner layer extends longitudinally along the gap between the chamfered edges and at least partially overlies the chamfered edges. A thermally-insulating solid insert is assembled from two or more parts to lie in the gap surrounding the inner layer, and pressure is applied radially inwardly from the insert to the inner layer. An outer layer of molten material is manufactured around the insert to form a watertight barrier and to form one or more melted interfaces with the inner layer. Corresponding field joint arrangements are also disclosed.
