Abstract: A control apparatus for controlling a machine, especially an injection molding machine, includes a bus board providing communication connections between different units, a wiring board, and a separate process module. The process module includes one or more process boards providing a base range of input/output (I/O) connections for the machines to be controlled. The process module can be directly connected to the bus board and the wiring board by means of a plug of second or third type, and thus produces a bridge, i.e. a connection, between the bus and wiring boards, thereby reducing wiring required between these boards At least one control module, which assumes the control tasks for the machine, can be plugged into the bus board by means of a plug contacts of first type.

Abstract: A penetrator, including a penetrator housing in which there is arranged an explosive charge and an ignition system for the triggering of the explosive charge. The penetrator housing consists of a composite of a steel outer housing and a heavy-metal inner component, whereby the heavy-metal inner component, at predetermined external dimensions of the penetrator, is provided for the reduction of the mass of the steel outer housing and thus leads to an increase in the volume of the explosive charge and correspondingly to an increase in the mass of the explosive charge.

Abstract: Insensitive explosive molding powders are provided that include an explosive component, a binder and a plasticizer. The insensitive molding powders include explosive crystals that are bound by a binder system. Moreover, the insensitive high explosive molding powder of the present invention has a bi-/tri-/tetramodal grain composition comprising coarse grain (280-360 ?m with an upper limit of 500-700 ?m) and fine grain (e.g., 35-45 ?m) explosive crystals that a bonded by a binder system comprising a plasticizer and a binder. The molding powder of the present invention is coated in waterless solvent process having a solvent content of less than 0.01 wt. % and is immediately ready for pellet pressing.

Abstract: A reactive armour module (14) including a sandwich structure (16) which is enclosed by a housing (18) and which is formed by at least one sandwich surface element (20) which is angled in a roof ridge shape and which has an HE-explosive layer portion (40) between a front plate (34) and an intermediate plate (36) and which has a damping layer (42) of elastic material between the intermediate plate (36) and a rear plate (38). Preferably at least two sandwich surface elements (20) which are angled in a roof ridge shape are arranged in mutually superposed relationship turned crosswire relative to each other.

Abstract: An insensitive, yet fully energetic high explosive molding powder using sonochemically aminated 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) as an energetic binder, i.e., adhesive, is provided. The sonochemically aminated TATB is used at a relatively low weight % level (less than 15% by weight) in comparison to conventional crystalline TATB.

Abstract: In a nanostructured reactive substance and a process for producing the same, intermixing of silicon and oxidizing agent on a nanometer size scale permits virtually direct contact between the fuel and the oxidizing agent, only separated by a barrier layer. After the barrier layer is broken open, fuel and oxidizing agent are spatially directly together and can react, liberating energy. The reactive substance has a high reaction rate in comparison with conventional reactive materials.

Abstract: In a card reader comprising a card stop 4 for a card 2 inserted into the card reader, the card stop 4 is rotatable out of the card path about an axis of rotation 6 extending transverse to the card path, and is rotatably coupled to an arm 9 which is deflectable about an axis of rotation 8 extending transverse to the card path and is pretensioned into a pivoting position engaging in the card path in the card inserting direction 3 behind the card stop 4. Insertion of a card deflects the arm against the action of a restoring force from the card path thereby also turning the card stop out of the card path. If a card of insufficient length is stuck in the card reader, it is pushed further by the inserted card and passes the deflected, i.e. effectless, card stop and is discharged from the card reader.

Abstract: Process for treatment of gases which are exhausted through a sinter bed in a sintering plant, wherein a distinction can be made between a cold zone of the sintering plant with relatively low gas temperatures and a hot zone of the sintering plant with substantially higher gas temperatures. The gases from the cold zone of the sintering plant and the gases from the hot zone of the sintering plant are exhausted and treated as separate partial flows.

Abstract: By virtue of at least 5% of octogen in relation to the hexogen explosive, insensitive behaviour is achieved in relation to high thermal loadings (Fast Cook Off).

Abstract: The preliminary cleaning stage for a dust extraction installation for blast furnace gas is comprised of a large-sized cyclone which comprises a vertical pressurized tank. A gas furnace gas line arriving from the blast furnace is connected to an axial delivery device situated at the upper end of the pressurized tank. The delivery device is configured such that it introduces the blast furnace gas into the pressurized tank in an axial direction. A swirl device with guide vanes is positioned below the axial delivery device and causes the blast furnace gas which is axially introduced into the pressurized tank to swirl about the axis of the pressurized tank.
