Abstract: 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.

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.

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.

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.

Abstract: In order to manufacture compound composite bodies having at least two lay with a support material made completely or substantially from a polymer and with a porous layer firmly connected thereto, a substantially microwave-permeable polymer is utilized for the support material and a polymer having microwave absorbing properties is utilized for the porous layer. The polymer for the porous layer, treated with foaming agent, is heated with microwave energy up to the decomposition temperature of the foaming agent. The resulting polymer foam is sufficiently heated using microwave energy that the support material, at its bordering layer adjacent the foamed polymer, is sufficiently melted substantially due to heat conduction out of the foamed layer that, subsequent to cooling, a firm composite between the support material and the foamed polymer is effected.

Abstract: In order to enlarge the surface of particles which absorb liquids at least o a limited extent, the particles are exposed to a liquid or to a humid atmosphere containing this liquid at least until said liquid has penetrated into the area of the particles close to their surface, and the liquid-containing particles are then irradiated with micro-waves until the penetrated liquid evaporates. The surface of the particles is torn down to the depth of penetration of the liquid and thus enlarged, or the particles break up, creating small broken pieces with an irregular and enlarged surface.

Abstract: 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.

Abstract: An apparatus and a method for the identification and encrypting/decrypting of messages permits converting an input message provided as characters, in character-by-character fashion and depending on preceding characters, to form an output message. An address branching network is employed for encrypting/decrypting. The address branching network includes selectable branches that are carriers of encrypting/decrypting characteristics. The selection of such branches is done in a step-by-step selection run through the branching network to convert any specific input message of optional length character-by-character into a specific selection path through the branching network. The output message is formed on the basis of the encrypting/decrypting characteristics from the branches selected on said selection path.

Abstract: A method for periodically refreshing dynamic MOS memories is provided in which the memory is divided into a number of separate memory sections, each containing a plurality of refresh locations, and the locations in one section are refreshed each time another of the sections is accessed for reading or writing. The refreshment of the refresh locations in each section is accomplished sequentially, and an index is maintained of which refresh locations have been refreshed during a refreshment period. At the conclusion of each such period, the remainder of the refresh locations in each section are refreshed. It is therefore unnecessary to restrict normal access to the memory for reading and writing during set periods which are set aside for the sole purpose of refreshing the memory contents, since refreshment occurs simultaneously with normal accessing. The mean access time is thereby decreased.
