A deliverable weapon, such as a missile, an artillery round, an aerial bomb, or a mortar round, having an explosive warhead, utilizes concentric annular sleeves that upon detonation provide placement of smaller fragments of an inner annular sleeve interstitially with respect to larger fragments of an outer annular sleeve in an expanding fragmentation curtain that contains expanding gases to increase the pressure of the explosion and the kinetic energy transferred to the fragments. In embodiments, the sleeves are comprised of ordered layers of spherical metal fragments encased in binder material and an outer casing.

A functional polymeric cutting edge structure and methods for the manufacturing cutting edge structures using polymeric materials are provided. A razor blade for use in a razor cartridge or a blade box for assembly in a razor cartridge frame may be formed using the present invention.

Provided is a method of manufacturing a light emitting device, comprising: preparing a base body having a concave portion; disposing a light emitting element at the bottom of the concave portion; disposing a first resin containing first phosphor particles having an average particle size of 10 m or more and 30 m or less and a first filler having an average particle size of 5 m or more and 20 m or less to cover the light emitting element; centrifugally precipitating the first phosphor particles and the first filler toward the base body; temporarily curing the first resin; disposing a second resin containing second phosphor particles and a second filler having an average particle size of 5 nm or more and 100 nm or less on the first resin temporarily cured; centrifugally precipitating the second phosphor particles and the second filler toward the first resin; and curing the first and second resins.

Devices, systems, and methods appropriate for use in medical training that include materials that better mimic natural human tissue are disclosed. In one aspect, multi-layer tissue simulations are provided. In another aspect, male genitalia models are provided. In another aspect, abdominal surgical wall inserts are provided.

The present embodiments generally describe a monolithic, e.g., integral, box unit and methods of manufacturing monolithic box units. The monolithic box unit has a ring portion and a body portion, both of which are molded and set simultaneously. The method proceeds with filling a female oriented cavity with a Polymer mixture, allowing both the ring portion and body portion to fill and cure at the same time. Once ejected from the cavity, the entire unit can be trimmed and then add hardware and cover to complete the box.

A method of filling a microcavity with layers of a polymer material includes the following steps: (A) estimating a current vertical position of a bottom of the microcavity (current bottom position); (B) lowering the capillary tube into the microcavity towards the current bottom position; (C) dispensing a polymer composition from a tube outlet of the capillary tube under a dispensing applied pressure until the polymer composition substantially fills the microcavity; (D) curing a work piece including the microcavity and the polymer composition in the microcavity to obtain a current layer of the polymer material; and (E) repeatedly executing steps (A), (B), (C), and (D), until the layers of the polymer material have substantially filled the microcavity.

A method for producing a first mold element for a metal machining tool, wherein the first mold element is configured as a holding-down mechanism, for producing the first mold element, a main body made of plastics material is provided, wherein a surface of the main body is subdivided into a plurality of regions, on at least one region of the surface of the main body, at least one casting mold is arranged, wherein the at least one casting mold and the at least one region of the surface enclose at least one cavity, which forms a negative mold for a layer of plastics material to be applied, wherein plastics material is filled into the at least one cavity and cured, wherein the plastics material in the at least one region is connected to the surface of the main body and applied to it, forming the layer.

A wind deflector for a vehicle roof having a displaceable cover element. The wind deflector can have an unfoldable deflector element made of a flat flexible material and whose lower edge portion can be fastened to a vehicle-mounted base via a lower edge strip and whose upper edge portion is fastened to a pivotable deploying bow via an upper edge strip. The lower edge strip and the vehicle-mounted base and/or the upper edge strip and the deploying bow can form a respective fastening system. The fastening system may have a fixing rib on one side and an arrangement of tabs attached to the fixing rib on the other side, the arrangement of tabs being formed by locking tabs and support tabs alternating along the fixing rib, the locking tabs and the support tabs being in contact with the fixing rib on sides facing away from each other.
