摘要:
A pyrotechnic mixture in the form of granulates, encompassing a nitrogen-generating substance, an inorganic oxidizing medium and a binder constituted of silicone rubber. Also disclosed is a process for the production of this pyrotechnic mixture, as well as a gas generator for an airbag which contains the pyrotechnic mixture as a propellent charge. The pyrotechnic mixture is in the form of granulates for a propellent charge which generates a non-toxic gas, encompassing the nitrogen-generating substance, especially an alkali metal azide or earth alkali metal azide, an inorganic oxidizing medium consisting of alkali metal nitrate and/or alkaline earth metal nitrate and silicone rubber.
摘要:
A hydrodynamic propulsion device possessing an expansion chamber located downstream of a cross-sectional widening for the inflow of a medium which is to be expelled through a discharge nozzle. The propulsion device is constructed as a static propulsion mechanism without movable components, in that the gaseous operating medium is produced in the propulsion device through the reaction of a hydrofuel, such as NaK with water.
摘要:
Polychlorinated waste materials such as polychlorinated dibenzodioxines (PCDD), polychlorinated dibenzofuranes (PCDF) and polychlorinated biphenyls (PCB) are subjected to nonpolluting destruction by combusting said materials together with waste sulfuric acids, acid tars and similar sulfur- and carbon-containing waste products of various compositions and consistencies in a multi-stage combustion furnace.
摘要:
In the electron beam generator cooling is provided by the electrical conductors of the incandescent cathode and control electrode which are configured as heat bridges and connected to cooling plates in the interior of the high-voltage insulator which in turn are connected in a heat-conducting manner to a pot-shaped cooling body. The cooling body, configured as part of a capsule for accommodating circuitry for the control of the electron beam generator, is surrounded by a heat exchanger which is connected to a cooling circuit and is at ground potential, and is insulated from the cooling body by a wall of the high-voltage insulator.
摘要:
A propellant igniter for a cartridge including an ignition tube which extends into the propellant; and with a booster charge arranged at one end of the ignition tube having a pyrotechnic igniting composition therein, which leaves the presence of a central passageway. The igniting composition or charge is formed from a tubular, hardened or set layer constituted of a pyrotechnic lacquer or varnish. Preferably, the pyrotechnic layer is cast into the ignition tube while in a pourable state, and then hardened or cured within the tube. The pyrotechnic layer can also be applied onto a combustible conduit tube for gas fumes, hardened thereon and then inserted into the ignition tube.
摘要:
A propulsion mechanism for a subcaliber projectile, wherein the propulsion mechanism possesses a close-fitted zone in common with the projectile for subjecting a gas pressure-receiving surface to a load caused by the propellent gases; for the utilization in a recessed surface, of an incident flow of air subsequent to exiting from a weapon barrel; and a tensioning device for the assumption of tensile stresses, with the device being connected with a central carrier component adjoining the projectile body.
摘要:
An incendiary projectile possessing an incendiary composition arranged locally bonded about the internal casing surface of the projectile wall structure. The projectile has the inner casing surface of its wall structure covered with the incendiary composition in fixed adherence therewith, and the explosive in the inner space of the projectile extends into grid-structured interspaces or scorings for the mutual bounding of covered regions. In this connection, there is also disclosed a particularly advantageous method for the formation of a projectile which is designed in this manner, as well as an expediently employable arrangement for the implementation of the method.
摘要:
A method and apparatus for vacuum coating of materials having a three-dimensional surface structure is disclosed that provides cooling, to prevent heat destruction of those materials during vacuum coating. The web is moved back and forth across the coating area, between rolls. A cooling film is rolled onto each roll with the web. As the web is unrolled, the film is unrolled and recooled before being rolled up again with the web.

摘要:
Copolymers obtained by copolymerization of vinyl esters of aliphatic carboxylic acids and/or acrylic or methacrylic acid esters of aliphatic alcohols, with half-esters of ethylenically unsaturated dibasic carboxylic acids, followed by neutralization with bases, are used in hair setting compositions.
