Abstract: Described is an arrangement for supporting a circuit board (28) having functional components (30) on a carrier (16) of a projectile (10). The carrier (16) has a metal plate (18). The circuit board (28) comprises a carbon fibre-reinforced plastic material. Provided between the circuit board (28) and the metal carrier plate (18) is an elastic damping layer (26). The circuit board (28) and the damping layer (26)—like the metal carrier plate (18)—are spaced with their peripheral edges from the inside wall of the housing of the projectile (10).

Abstract: An inverter-fed three-phase electrical motor (1) for a household appliance is grounded through a protective conductor (8), with the motor being particularly provided for the direct drive of washing machines. The motor includes a pick-up for high-frequency currents originating from an actuation of the inverter (7) and conducts the currents to one pole of a D.C. voltage supply (13) for the inverter (7) through an ohmic or capacitive shunt path (18-19), with the shunt path leading from a stator (3) of the motor which is installed electrically insulated into the household appliance and is not connected to the protective conductor (8).

Abstract: Provided is to an ultrasound sensor for a fumes extractor hood, wherein the sensor monitors the vapor rising from the cooking to the extractor hood. Automatic compensation in respect of temperature and ageing drift of the sensor is effected. For that purpose checking of the resonance frequency is implemented cyclically during on-going operation of the sensor, in which case a shift in the resonance frequency is recognized, and the new resonance frequency is established by a statistical calculation method and used for further operation of the sensor.

Abstract: A propellent charge powder for barrel-type weapons having a plasticizer on the basis of nitramine and nitrocellulose, nitramine and energetic and non-energetic plastic binders, or nitrocellulose or an explosive, and wherein the plasticizer is a mixture of at least two chemically different dinitro diaza compounds. The plasticizer facilitates the production and use of the propellent charge powder possessing a low temperature coefficient.

Abstract: The detector circuit (11) of a radiation-sensitive sensor (10) with capacitive high pass coupling (14) between a pre-amplifier (13) and a signal amplifier (15) is blocked for a prolonged period of time (T2) even after termination of an overexcitation effect, because of the high filter time constant of the series capacitor (25), because the capacitor (25) only slowly experiences charge reversal and therefore the signal amplifier (15) following it initially still remains overdriven until the capacitor (25) has reversed charge again to a dc voltage level in the actuation range (39) of the signal amplifier (15). That dead time period (T2) is however curtailed to a short fraction (T1) if upon termination of overexcitation at the input side the capacitor (25) at the output side, that is to say upstream of the signal amplifier (15), is forcibly returned to the—virtual—ground potential at the amplifier input, for potential reduction purposes, by way of a low-resistance switching section (31).

Abstract: A blast shell is launched as a defense against an attacking tail fin-stabilized projectile, such as in particular a KE penetrator, from an object which is to be protected. Gas fumes and a reaction pressure blast wave from a fired blast warhead of the shell act principally on the tail region of the attacking projectile and thereby deflect the latter from a trajectory in the attack direction so that the object under attack is either missed or at least is not hit in a head-on direction, thereby reducing the effectiveness of the attacking projectile.

Abstract: A guided missile (12), in particular a projectile which can be fired through a propellent charge gas pressure, having rudder blades (18) which cross each other and which can be pivoted open to steer the missile (12). Each rudder blade (18) is mounted in a guide slot (22) which is closed at the front end by an end portion (26). Each end portion (26) has a spoiler end face (28). Each end portion (26) projects radially beyond the lateral longitudinal ribs (24). At its distal end portion (32) the associated rudder blade (18) is provided with laterally mutually opposite, narrow guide ribs (36) which project out of the rudder blade profile (34).

Abstract: Items of relative target location information (19) which are obtained on board a platform serving as a sensor carrier (13) for target or position reconnaissance are combined, with association with the navigation satellite system time (34), with items of absolute mission location information (25) which are obtained on board the sensor carrier (13) from the satellite navigation orbit data (22), in order to obtain absolute target position data in which however, due to the system, there is still contained the absolute residual error of the order of magnitude of some ten meters, from the satellite-aided mission location determination.

Abstract: To maintain control accuracy for the pivotable rudder blades (14), which lie in a combustion chamber, of a guided projectile (12) which can be fired by means of propellent charge, there is provide a mounting arrangement in which the trunnions (20) of the rudder blade holders (16) of the diametrally mutually opposite rudder blades (14) are torsionally stiffly rigidly connected through an associated coupling element (32) which is limitedly resilient in the radial direction of the guided projectile (12).

Abstract: Described is a testing system which has a target point light source (12), a tracking light source (18) and therebetween a projection wall (24). Associated with the target point light source (12) is a two-axis deflection device (28) which is connected together with a target point computer (14). Associated with the tracking light source (18) is a two-axis scanner device (30) which is connected together with a tracking computer (20). Provided between the tracking light source (18) and the two-axis scanner device (30) is a beam splitter (32) with which a sensor device (42) is associated.

Abstract: A pseudo-noise-modulated spread spectrum is irradiated undirectedly--or, encoded by different modulation, into mutually displaced spatial sectors--and the energy (20) received after reflection at a potential target (13) is cross-correlated, using the pseudo-noise code which is predetermined at the transmission end, in order to provide a spherical monitoring effect which is continuous but which cannot be located in respect of its origin, to provide a warning in particular for marine craft, land vehicles and aircraft against an attacking guided missile as the target (13) to be repelled, and in order to be able to transfer to a target tracker (12) distance and speed information obtained from the correlation product, with the alarm signal, if the alarm sensor (11) is not itself also used as the tracking sensor.

Abstract: A lighting arrangement for a space or compartment (2) which can be closed off, with a fire-proofing ceiling (3), in particular for receiving freight in passenger aircraft, comprising lighting units (6) arranged in the fire-proofing ceiling (3), which for the purposes of static load relief of the fire-proofing ceiling (3) and at the same time for a better lighting effect for the space or compartment (2), has the following features: a plurality of through openings (19) are arranged in distributed fashion in the fire-proofing ceiling (3), fire-resistant light coupling-out elements (16) are arranged in the through openings (19) in such a way that their light cones (9) intersect in the space or compartment (2) and the light coupling-out elements (16) are connected by way of optical waveguides (14) to at least one common light source (15).

Abstract: A target acquisition apparatus (10) having a laser beam source (12), wherein associated with the laser beam source (12) is an opto-mechanical tracking device (14) having a receiver (38) for reception of the laser beam which is reflected by a target (28). For evaluation of the signals of the receiver (38) there is provided an electronic evaluation device (18) which is connected together with the opto-mechanical tracking device (14). The receiver (38) has a photovoltaic four-quadrant detector (36) by which two orthogonal spatial direction co-ordinates (X, Y) are established. In order to compensate for dissimilar performance on the part of the quadrant detectors (E1, E2, E3, E4) of the four-quadrant detector (36) as is not to be ruled out for example due to temperature-induced or ageing-induced drift, the electronic evaluation device (18) is provided with switches (S1, S2, S3, S4) for signal inversion purposes.

Abstract: There is provided a control device for a gas burner used for gas cookers, in which the gas burner is connected to a flame monitoring device. The flame monitoring device has a timing device (11) which regulates a closing mechanism of a gas valve (7) or a gas control unit (2) in accordance with a predetermined switch-on time and/or a predetermined switch-off time. In that arrangement the control device (11) can act directly on the gas valve (7). It can however also act on an electromechanical relay (20) or an electro-hydraulic relay (21) which are each connected to a respective bimetal control device of the flame monitoring device.

Abstract: A sensor arrangement for target-seeking ammunition which includes an insert for forming a hollow charge, and in front of which there is positioned a transducer for electromagnetic radiation energy. The sensor arrangement of the above-constructional type has the transducer located in the longitudinal axis of symmetry of the ammunition and of the insert. The insert forming the combat charge may itself serve as a focusing reflector for the operating characteristics of the sensor arrangement. Inasmuch as there is available for the aperture practically the entire caliber of the ammunition; in effect, the front surface of the insert facing into the effective direction, there can be obtained an extremely favorable operating characteristic for the sensor arrangement.

Abstract: In an infantry grenade (5) the fragmentation effect is enhanced in that a cup portion (7) of a ductile steel--which serves to receive an explosive charge (9)--has at its periphery in a substantially cylindrical longitudinal portion (25) a pre-notched fragmentation arrangement (28, 29) and in a rounded longitudinal portion (26) ball-type fragmentation portions (32). The entire fragmentation arrangement is enclosed by a plastic shell (17).

Abstract: A friction element has a base element on which a coating is applied by thermal spraying of a copper alloy. The copper alloy contains 27 to 35 wt % zinc, 4 to 6 wt % aluminum, 2 to 4 wt % nickel, 0.5 to 2 wt % titanium, and copper as the remainder, with random contaminants. The copper alloy is applied onto a base element by thermal spraying, and requires only a finish treatment by stamping to achieve good tribological properties and wear resistance that are comparable to molybdenum coatings. Alternative copper-zinc alloys can have, in particular, manganese, iron, and lead constituents.

Abstract: The invention relates to the use of a brass alloy with a high degree of cold workability for sanitary pipes, comprising 60.5-63.2% Cu, 2%-3.7% Pb, the balance Zn, plus normal impurities, wherein the effective copper equivalent is 63%-64.5% Cu. The use of cheap scrap in production of the alloy is possible by virtue of admitting lead and impurities. A very good degree of cold workability is afforded by virtue of the copper equivalent which is comparable to that of MS 63. The use of cheap return scrap causes the production costs for the alloy to be significantly below those of MS 63.
