Abstract: The invention relates to a device and a method for disabling electronic devices in order to reliably prevent third parties from gaining unauthorized knowledge of data in the event of loss of the storage medium. The device comprises a gas generator, with a pyrotechnic propelling charge, disposed in the area of the storage medium. At least one fuel or at least one oxidator of the propelling charge releases, when the latter is triggered, well conducting metals, especially precious or semi-precious metals which are deposited on the electronic parts of the electronic device. According to the inventive method, the igniter can be triggered manually, by sensors or remote-controlled. The invention further relates to an electronic data processing system and a telephone comprising such a device.

Abstract: The invention relates to a self-defence module comprising a housing containing a chamber that holds a free-flowing active medium and comprising a compressed gas source for spontaneously dispensing the active medium from the chamber. In order to be able to miniaturise the self-defence module, the compressed gas source is configured from a pyrotechnic gas generator and an ignition unit that interacts with the generator. According to the application, the ignition unit can be triggered manually or by a sensor. The invention also relates to the use of a self-defence module of this type for the protection of persons, buildings, means of transport or valuables.

Abstract: A method for the protection or defence of moving objects or persons, characterized in that in the case of endangerment, at least one sleeve-type element is inflated from a collapsed space-saving state by means of a gas which is introduced into said sleeve or by means of a gas generated medium to form a barrier. In this way, efficient and flexible protection of systems, buildings or the like can be protected with non-lethal means. As a result, the inventive method or device suitable for carrying out said method can be used in a multiplicity of ways such as to prevent access or influence groups of persons at large public events.

Abstract: The invention concerns a composition for the production of shaped bodies, consisting of polymer lignin, shellac and natural fibers and also a method for the production of shaped bodies from such a composition via production of a shaped body through extrusion.

Abstract: For producing a granulated intermediate product which consists of a fine-particle thermoplastic or thermoelastic polymer and substantially inert fillers for further processing into plastic shaped bodies through thermoplastic processing methods it is proposed to mix the polymer in the form of powder or particles with the fillers and compact the powder mixture without plastification of the polymer exclusively under mechanical pressure into pourable agglomerates with larger grain size. Such an agglomerate can be processed into shaped bodies in the same manner as a conventional plastic granulated material, wherein thermal damage to the fillers and the molecular structure of the polymer is reliably prevented during production of the intermediate product and extremely high fill fractions can be achieved.

Abstract: A propellant device of consisting of a compact charge and a firing system for pipe weapons or ballistic drives is proposed. At least one electromagnetic radiation absorbing medium, e.g. carbon black, is dispersed in the compact charge and can be activated by means of a firing system emitting electromagnetic radiation. The compact charge is thereby disintergrated in fragments through triggering of the firing system and the fragments are accelerated into the gas volume produced during burning of the compact charge. The inventive propellant device avoids the use of chemical firing as well as mechanical firing means. Moreover, fragmentation of the compact charge permits maintenance of the produced maximum pressure over a longer period of time to impart a higher muzzle velocity to an object to be accelerated, e.g. a projectile, a rocket or the like.

Abstract: A plastic material made from a polymer blend, is characterized in that said material contains at least one lignin-based natural polymer, in particular based on alkali lignin produced during the extraction of cellulose, and at least one other synthetic and/or natural polymer which increases the impact resistance, proteins excluded. The inventive plastic material has excellent characteristics. It is biodegradable due to the natural polymer content and has, to a considerable extent, an ecologically neutral CO2 balance. The polymer blend can be used advantageously in place of wood or wood materials.

Abstract: A method for producing a substantially rod-shaped composite body (6) consists of a core (4) enveloped by at least one polymer, according to which the plasticized polymer (5) is extruded onto the core (4). At least one natural polymer is used and a sliding agent on the basis of native oils and/or waxes is added before or during extrusion. The method is used for the production of writing, drawing, cosmetic pencils.

C. and in a proportion of up to 10% is either mixed with further AN and melted, homogenized and subsequently transferred into the solid state, or mixed with further AN is incorporated into the AN lattice at between 80.degree. and 170.degree. C. in a solid-state reaction.

Abstract: A method for investigating a volume change of a sample under tension, with a sample being scanned by a first light beam and the light beam reflected from the sample being detected and further processed. The sample is then illuminated with at least one additional light beam of finite width, with the light beam being converted into a first voltage behind the sample, and a transverse pattern of different reflectivity is scanned by the first light beam longitudinally, and with the change in frequency, produced by stretching, in the reflected light intensity-modulated in this fashion being converted into a corresponding second voltage and the voltages are compared with one another, possibly after calibration.

Abstract: A method is disclosed for measuring the rate and/or extent of movement of oscillatory element positioned on an oscillating system by passing a reference beam towards a reference detector over a reference edge. The reference edge is fixed relative to the element. The measurement beam is directed towards the measurement detector over a measurement edge of a surface adapted to move together with the element relative to the reference edge. The movement of the measurement edge cuts the measurement beam as it moves into the path of the measurement beam. The rate and/or extent of movement of the element relative to the reference edge is determined by comparing the illumination received by each of the detectors. Apparatus is also disclosed for measuring the rate and/or extent of movement of an oscillatory element positioned on an oscillating system including a measurement edge adapted to move together with the element. A reference edge is maintained stationary relative to the measurement edge.

Abstract: A parallel pencil of light, for example, a laser beam, is expanded by means of a cylindrical lens. The lens is fully cylindrical and has an optically thinner medium of cylindrical shape in its interior. The lens is arranged relative to the pencil of light so that total reflection occurs at the interface with the optically thinner medium.
