Abstract: In an artificial nail preparation comprising at least one synthetic resin layer and a textile fabric cast into the synthetic resin layer, the thickness of the textile fabric is equal to the thickness of the synthetic resin layer. In order to produce the nail preparation the textile fabric is de-aerated by means of a liquid synthetic resin, wherein the textile fabric is immersed in the liquid synthetic resin and the immersed textile fabric is coated with a film material, thereby producing an intermediate product. Then the intermediate product is formed reproducibly, the liquid synthetic resin enclosed in the formed intermediate product is cured and the film material is separated from the cured synthetic resin, so that nail preparation blanks are obtained. A device for carrying out the method has a pultrusion machine which has two film web offtakes as well as a textile web offtake disposed between the film web offtakes.

Abstract: The cartridge ammunition (1) comprises a projectile (11) and a cartridge shell (10) receiving the same. The cartridges of the ammunition are magazined in a belt (31) and are pulled out of the belt by means of an unbelting device and transferred into the lock of the automatic firearm so that the individual projectiles (11) can be shot from the automatic firearm at a high shooting frequency. To minimize the forces abruptly exerted on the bottom flange of the cartridge shell (10) by means of the removal of the cartridge ammunition from the belt, at least one recess (33) is provided in the bottom flange (32) of the cartridge shell (10), thus increasing the bending elasticity of the bottom flange, e.g. by reducing the thickness of the bottom flange. The recesses (33) may e.g. be designed as a groove (33a) or as a series of blind bores (33b) that extend in parallel to the edge of the bottom flange.

Abstract: A process for the production of hydrogen, comprising the steps of: (i) providing a photosynthetic microorganism having electron transfer capability through a photosynthetic “light” reaction pathway and through a respiratory electron transfer chain involving an oxidative phosphorylation pathway, and which expresses a hydrogenase, wherein regulation of the oxidative phosphorylation pathway is disrupted with the result that electron flow along the respiratory electron transfer chain toward cytochrome oxidase (complex IV) is reduced; ii) culturing the microorganism under microoxic and illuminated conditions; and (iii) collecting evolved hydrogen.

Abstract: In order to improve a pull-rope type starting device (100) for an one internal combustion engine, having at least one rope drum (4) which is rotatably held in a housing (1), wherein said starting device, for generating the drive torque for the motor shaft by means of a starter handle, is rotatable by way of a starter rope or pull-rope, and by way of an elastic coupling element (6) connected to a ratchet-type engaging element, by means of which the drive torque can be transmitted to the motor shaft, such that the elastic coupling element (6) or a part thereof can simply, effectively and reliably be prevented from entering a design-related gap between the rope drum (4) and the engaging element (5), it is proposed that a bushing or sleeve (8) be provided in this gap.

Abstract: The invention pertains to a handheld implement, in particular a portable chainsaw (100), with a handle housing part (12) that contains at least one carrying handle (10), and with at least one motor housing part (16) that carries a drive unit (14) and is connected to the handle housing part (12) by means of an antivibration system that consists of at least one vibration-reducing element (18). The invention proposes an antivibration system of this type, in which the above-mentioned problems are solved due to the fact that an exchange of the vibration-reducing elements can be eliminated, wherein the antivibration system is still able to fulfill the individual requirements of the operator and the machine. This is achieved due to the fact that the at least one vibration-reducing element (18) is realized such that it can be adjusted with the aid of a tool or without requiring a tool.

Abstract: A starting device is provided for an internal combustion engine, in particular a pull-rope type starting device for a two-stroke or four-stroke motor. The starting device includes a pulley or rope drum which is rotatably held in a housing, and generates the drive torque for a motor shaft by means of a starter handle or pull handle. The starting device is rotatable by way of a load transfer means, in particular by way of a starter rope or pull-rope, and by way of an elastic coupling element, in particular by way of a spiral spring. A ratchet-type engaging element is provided, by means of which the drive torque can be transmitted to the motor shaft, such that not only is overloading of the elastic coupling element prevented in a safe and reliable manner, but also, even if the elastic coupling element should break, the starting still functions, and the internal combustion engine can still be started.
