Полезная модель относится к прострелочно-взрывной аппаратуре, конкретно - к облицовке кумулятивного заряда. Задачи создания полезной модели: увеличение глубины пробития кумулятивных зарядов и расширение арсенала средств определенного назначения, т.е. кумулятивных зарядов. Достигнутый технический результат: увеличение глубины пробития кумулятивного заряда на 30%…40%. Решение указанных задач достигнуто в облицовке кумулятивного заряда, содержащей свинец и высокоплотный порошок, тем, что облицовка выполнена многослойной и содержит внутренний низкоплотный слой и внешний высокоплотный слой, при этом высокоплотный слой сосредоточен на внешней стороне облицовки, а в качестве высокоплотного порошка использован вольфрам в количестве от 80 до 90 мас.%. Вольфрам может быть применен в виде частиц размерами от 5 до 50 мкм.

Such propellant compositions include a cellulose-based organic fuel, a non-azide, nitrogen-containing primary organic oxidizer and a secondary nitrate, perchlorate, chlorate of peroxide oxidizer. Preferably, such compositions are in the form of extruded shaped hollow cylindrical grains having dimensions that makes it loadable in a muzzleloader firearm or small calibre firearm cartridge case. Ignition grains are also provided for use alone or in a mixture with the propellant compositions. When used in a small calibre firearm or muzzleloader, the temperature of combustion is at a level that ensures substantially complete combustion of the fuel during firing so that the products of combustion are mostly gaseous.

Method for applying soft solder to a mounting surface of a component

Номер: US20120297616A1
Автор: Dominic Schroeder, Matthias Schroeder
Принадлежит: JENOPTIK LASER GMBH

The invention relates to a method for applying soft solder to a mounting surface of a component, wherein a connecting means comprising a carrier layer and a soft solder layer formed by physical vapor deposition on the carrier layer is brought into mechanical contact between the soft solder layer and the mounting surface, such that a first bond strength between the soft solder layer and the mounting surface is greater than a second bond strength between the soft solder layer and the carrier layer. The connecting means is subsequently removed from the component so that the carrier layer releases from the soft solder layer in the area of the mounting surface and thus soft solder remains only at the mounting surface.

Systems and processes for forming molds such as nickel molds

Номер: US20130048502A1
Автор: Christina Yuan Ling Tan, Isabel Rodriguez, Jarrett Dumond, Kambiz Ansari, Yee Chong Loke
Принадлежит: Agency for Science Technology and Research Singapore

For forming a nickel mold, a metal and a corresponding etchant are selected such that the etchant selectively etches the metal over nickel. The metal is sputtered onto a surface of a template having nano-structures to form a sacrificial layer covering the nano-structures. Nickel is electroplated onto the sacrificial layer to form a nickel mold, but leaving a portion of the sacrificial layer exposed. The sacrificial layer is contacted with the etchant through the exposed portion of the sacrificial layer to etch away the sacrificial layer until the nickel mold is separated from the template. Subsequently, the nickel mold may be replicated or scaled-up to produce a replicate mold by electroplating, where the replicate mold has nano-structures that match the nano-structures on the template. The metal may be copper.
