Abstract:
Packaged sticks of stiff slurry blasting composition are produced by apparatus and method which (1) form a slurry of pumpable consistency by blending together a solution of inorganic oxidizer salts, such as ammonium nitrate, sodium nitrate and/or others with solid fuels and/or sensitizers, (2) pump the slurry, by means of an air-diaphram pump, through a hollow mandrel or tube, (3) package the extruded slurry as it emerges from the mandrel by encompassing the composition in a packaging material of tubular shape, which is either surrounding or sealed around the extruded slurry, (4) performing a tying and cutting operation between successive lengths to form sticks as they are filled, and (5) conveying the filled sticks to packaging or delivery, all in a continuous process.
Abstract:
The present invention relates to a manufactured graphene/metal or metalloid core-shell composite and manufacturing method thereof. The method comprising: using a modified graphene oxide as a base, then performing concentration and steam drying followed by organic solvent replacement to obtain a modified graphene oxide organic solvent; using a liquid-phase self-assembly method to coat the modified graphene oxide onto a surface of the metal or metalloid to form a graphene/metal or metalloid coated particle solution, then filtering and drying to obtain the graphene metal/metalloid core-shell composite. The method improves upon a conventional organic and inorganic material coating technique, and reduces an impact of a water-based solvent and high temperature on a highly reactive metal and metalloid, thereby expanding the feasibility of the coating technique and addressing a barrier of applicability of graphene and reactive metal or metalloid in the field of energetic materials.
Abstract:
A photostructurable ceramic is processed using photostructuring process steps for embedding devices within a photostructurable ceramic volume, the devices may include one or more of chemical, mechanical, electronic, electromagnetic, optical, and acoustic devices, all made in part by creating device material within the ceramic or by disposing a device material through surface ports of the ceramic volume, with the devices being interconnected using internal connections and surface interfaces.
