Abstract: An acoustic warning device for a vehicle is disclosed. The acoustic warning device includes an air suction device having a suction tube, and a filter housing having a filter and a sound generating device which is arranged therein. The sound generating device is arranged between suction tube and filter with respect to a flow direction of the air. The sound generating device firstly emits the acoustic signal into a spatial volume of the filter housing. An additional chamber volume serves as a band-pass filter for the sound waves emitted from the sound generating device. The acoustic warning device may further include a sound source arranged outside the filter housing to generate sound signals with higher frequencies than emitted from the filter housing. By the combination of these two sound generating devices, an efficient emission of low-frequency and also of high-frequency sound signals is therefore possible.

Abstract: A process and apparatus for converting starting materials containing hydrocarbon into a hydrogen-rich product gas is disclosed. A raw synthesis gas containing hydrogen (H2) and carbon monoxide (CO) is generated from the hydrocarbon-containing starting materials in a first process step of which at least a part undergoes a catalytically supported water-gas shift reaction to increase the percentage of hydrogen. The water-gas shift reaction is carried out at temperatures between 50 and 200° C., preferably between 60 and 150° C., and at temperatures between 1 and 10 bar, preferably between 1 and 5 bar, in a reactor in which a suitable catalyst is present.

Abstract: At least one hydrogen-containing product stream (4) can be obtained from feedstocks (1) that contain organic oxygen compounds with more than one carbon atom. In the process, an intermediate product is obtained from the feedstock (1) in a first process step in a first reactor (P). The intermediate product is then reacted by steam reforming in a steam-reforming reactor (steam reformer) (D), which is heated from the outside, to obtain a synthesis gas (3) that contains hydrogen and carbon monoxide.

Abstract: The invention relates to a process and an apparatus for producing a profiled sheet, in which the sheet is provided with a corrugation which runs obliquely with respect to the edges of the sheet and has a substantially constant angle of inclination. At least one edge region of the sheet is deformed by means of a ram-like deformation tool (6) which is alternately brought into contact with the edge region and removed from the edge region.

Abstract: A fragmentation plate composed of juxtaposed contacting metal bodies or fragmentation elements which is to be disposed in front of an explosive charge in an explosive grenade or other projectile, for example a sub-projectile. The metal bodies or fragmentation elements, for example, metal balls, are held, at least on the side of the plate facing the explosive, by a tray or shell, for example of sheet metal. The tray or shell may be perforated, i.e. provided with holes, for the metal bodies. Moreover, an encasing substance may be disposed between the tray and the bodies and over the outer surfaces of the metal bodies. Additionally, the fragmentation plate may have an outer covering shell or tray.

Abstract: The electrical apparatus combination includes a plurality of electrical components which are for instance an outlet apparatus socket, an inlet apparatus plug, an apparatus switch and a filter which in order to allow an electrical interconnection are arranged on a printed circuit board onto the reverse side of which conductors are placed onto which contact members such as contact prongs located in each electrical component and plugged onto the circuit board are soldered. A releasably mounted protective cover protects the bottom side of the printed circuit board which comprises the conductors and confers additional stability to the apparatus combination. The printed circuit board replaces the otherwise necessary electrical wiring between a plurality of electrical components having various functions.

Abstract: A casing for a projectile that includes a combustible propellant container is improved by the addition of a flexible spring steel bearing plate that includes a number of holes for the purpose of facilitating combustion of the propellant container and a number of radial slits to increase the plate's flexibility.

Abstract: A fin-stabilized subcaliber projectile having a drive cage comprising a plurality of segments and surrounding the body of the projectile in its central region. A tail disc is fastened to the cage and jointly covers the segments and tears in the region of the joints upon the release of the cage. Both the tail disc and a plurality of reinforcing segments corresponding to the drive-cage segments, and a connecting piece produces the connection to a burnable cartridge case disposed at the tail end of the drive cage one behind the other, these elements being connected to the drive cage by means of non-burnable fastening means.

Abstract: A cartridge shell has a cup-shaped metallic case stub whose rim is internally recessed to form an annular shoulder against which an inner skirt of a polymeric sealing ring, forming an extension of that rim, comes to rest while being flush with the inner cup surface. The rim portion of reduced thickness may be adhesively bonded to the skirt internally overlying same; that portion may form an annular web with an enlarged edge bead received with a snap fit in a complementary annular groove of the sealing ring separating the inner skirt from an outer skirt concentric therewith.
