In a method for applying a surface structure to a solid body, a structured surface is placed directly or indirectly onto the surface of the solid body and the structure of this structured surface is reproduced in the surface of the solid body, in that an explosive structured layer is arranged on the surface of the solid body and the structure of the explosive structured layer is explosively disseminated into the surface of the solid body. According to the invention, the surface of the solid body is provided with a surface pre-structure before the actual dissemination, at least in regions, wherein the structure of the explosive structured layer is disseminated on at least one partial region of the surface pre-structure so that the surface structure produced results from overlapping of the surface pre-structure with the explosively disseminated structure.

The invention relates to a fixing means which is used to temporarily fix human or animal body parts. The fixing means comprises at least one flexible carrier layer which is coated with a hardenable material, wherein the body part which is to be fixed can be surrounded either fully or partially by the fixing means and the hardenable material can then be hardened, wherein the carrier layer is stiffened. In order to provide for individual fixing of the body part while guaranteeing a partial adjustment of the desired rigidity of the fixing means, the fixing means is provided with at least two carrier layers, with at least one outer layer made of a flexible polymer film and at least one inner layer made of a flexible film in addition to at least one substantially liquid or viscous layer which is arranged between the outer and inner layer and which is made of at least one hardenable adhesive. It is thus possible to obtain the desired degree of rigidity when the adhesive has hardened by exerting manual pressure on the fixing agent which enables the hardenable adhesive to be displaced.

The aim of the invention is to provide an alternative to the intensive treatment of a product, especially plasma treatment, in specific areas only. Towards this end, the invention provides a device for producing microwaves for treating workpieces, comprising at least one microwave antenna with an extended conductor for producing alternating electromagnetic fields, a housing that substantially extends over the length of the conductor, and an extended microwave decoupling area which follows the conductor and which is located in the housing. The housing is formed by at least one resonant cavity, which has a long shape and follows the course of the microwave antenna. The resonant cavity has at least one tapering, closed, first crown area and the decoupling area essentially extends in the focussing area of the resonant cavity. An at least non-divergent housing area adjoins the resonant cavity.

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.

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 CO balance. The polymer blend can be used advantageously in place of wood or wood materials.

A method for producing a substantially rod-shaped composite body ( ) consists of a core ( ) enveloped by at least one polymer, according to which the plasticized polymer ( ) is extruded onto the core ( ). 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.

A method for the production of molded bodies comprising foam particles is proposed in which the foam particles are shaped and welded together using microwave energy. The foam particles are accommodated in a foil-like bag and the bag is manually shaped or shaped through the use of a shaped mold with simultaneous change of the shape of the foam particles, and evacuated into a dense package. Microwave energy is subsequently used to melt together at least the surfaces of the foam particles. The method in accordance with the invention is particularly well suited as an economical manufacturing technique for packaging, in particular specialized packaging for models, small production runs, prototypes and the like.

The present invention relates to a method for surface structuring of workpieces, in particular molds for plastics processing, erosion electrodes or the like, in which a structured surface is applied to an unstructured workpiece surface in order to map the structure into the workpiece surface. In order to provide a method which can be carried out more quickly, and which involves no environmentally hazardous process steps, it is proposed that a structure layer which has the structured surface is arranged between an explosive layer and the workpiece surface, and the structure is forced into the workpiece surface by detonating the explosive layer or a surface-structured explosive layer is arranged on a workpiece surface, and the structure is embossed onto the workpiece by detonating the explosive layer. The invention furthermore relates to a workpiece produced using this method, such a an injection-molding mold, a blowing mold, a compression mold, a foaming mold and a pressure-casting mold, erosion electrode or the like, in which the structure is forced into the workpiece surface by means of an explosive layer.

It is the object of the invention to realize a low-cost, low-effort cryptoanalytically secure encrypting/decrypting method for high data rates and large code key spaces. The solution provides for a message encrypting/decrypting system whereby the keys are contained in a memory in the form of a branching network with cross-linked nodes and branches. For encrypted/decrypted data transmission by process participants, it is possible to realize the cryptological functions 'authorization', 'identification', 'authentication', 'electronic signature', 'one time key', among others. The solution is especially usable in the application fields 'electronic access and data securing', 'telecommunication services', and 'electronic bank and payment services', for example, for the cash money substitution.
