When arranged in a predetermined, face-to-face relationship and secured by one or more connecting rods, the functional surface of each rib unit defines a surface of a furniture piece, such as a chair or bench seat, while each leg or supporting member is offset from the neighboring leg or support member according to a pattern which, when combined with the legs or supporting members of the other rib units, provides support for the entire furniture piece and its occupant.

Abstract: The invention is based on the concept of providing a digital data transmission of the fuze-timing data into a fuze-timable ammunition unit, for example with an HDB-3 (High-Density Bipolar) transmission code and voltage modulation. As is known from asynchronous data transmission, a start byte and a stop byte are respectively positioned in front of and behind the HDB-3 code, and are therefore components of thee fuze-timing data. The fuze-timing time is transmitted numerically as a data byte between the start and stop bytes. Accordingly, the ammunition unit (3) includes fuze-timing electronics (4), which comprise a (voltage) demodulator (30), a (current) modulator (31) and a microprocessor (32) having an RC-oscillator cycle counter (32.1), an RC oscillator (33), a fuze-timing counter (34) and an actuator end stage (36). A firing sensor (35) serves as the fuze-timing-time triggering element at the start of the flight phase.

Abstract: A disk-shaped propellant module (6) for a propellant charge (2), which can be composed of several modules of this type. To ensure a uniform and symmetrical ignition of the propellant charge (2) for a cartridge with increased charge density (>1.2 g/cm3), the propellant module (6) is provided with at least three axially extending ignition channels (9), uniformly distributed over a partial circle, and at least three radial ignition channels (10) that extend from the inside or interior of the propellant module (6) to its outer edge surface (11). The center of the circle for the axial ignition channels (9) is positioned on the central axis (100) for the propellant module (6) and each of the radial ignition channels (10) intersects with at least one of the axial ignition channels (9).

Abstract: A high-power microwave antenna in which, in order to radiate a pulse (8), the antennas (4) of the high power microwave are actuated by a pulse-generating source (3) and are embodied normally as wire antennas, horn antennas or the like. In particular for HPM active systems (1) to be conveyed, the antenna aperture of the antenna (4) is limited by the geometric edge dimensions of a carrier system (2) for the HPM active system (1), which further leads to a reduction in the efficiency of the antenna (4). According to the present invention, the antenna (4) is integrated into an airbag (5) that is inflated for operational use and thereby simulate the antenna (4). The antenna airbag (5) is inflated near a target (100) onto which at least one pulse (8) must be radiated.

Abstract: A method and a device for measuring wear on the internal surfaces (12) of barrels (1), in particular weapon barrels. For a very precise determination of the wear on the internal surfaces (12) of barrels (1), a non-contacting scanning of the internal surface (12) of the respective barrel (1) to be checked is carried out with a light-spot triangulation sensor (6), to determine the respective distance between the internal surface (12) and the barrel axis (7) for selected sensor positions. The contour of the internal surface (12) of the respective barrel (1) is then determined from the detected distance changes. It has proven advantageous if the measured distance values are displayed on a monitor (23) in the form of a C-image, wherein different distance ranges are characterized with different colors, so that faulty surface areas can immediately be recognized optically.

Abstract: A needle (1) for loop-forming machines has a needle body (2) with two even flat sides (6, 7), which are joined to one another on the top and back sides of the needle by narrow sides (5, 8). A narrow slit opens out at one of the narrow sides and extends parallel or at an acute angle to the flat sides (6, 7) into the needle body. A substantially rectangular fastening portion (21) of the transfer spring (14) is retained in this slit (16) by positive and/or nonpositive and/or material engagement.

Abstract: A workpiece can be clamped between the jaws of a vise in a defined position easily when it is supported by positioning pins. They are located in a plurality of bores in the jaw and can be projected out of the jaw in operation. The pins comprise a pin body and a stop member. Both elements provide a shape which allows an economical production and easy connection with each other. In normal operation the pins can be projected out of the jaw by fluid pressure and be pushed back manually. A bent pin can be pushed or pulled to the front out of the jaw easily by destroying the stop member in a predetermined way or separating it from the pin body.

Abstract: A cartridge having a propellant-charge casing (2) and an electrothermal ignition device (4), in which the propellant-charge casing (2) is connected to a metal casing base (3) and a contact piece (5) that is connected to a contact disk (9) is provided for the connection to a gun-side high-voltage electrode (22. To assure an automatic operation of corresponding weapons systems, during use of such cartridges, the contact piece (5) is formed such that it does not protrude past the outside surface (27) of the floor piece (7) on the outside, and on the inside, the contact piece forms the contact disk (9), which is supported over a large surface area against the propellant-charge casing (2) by a relatively thin-walled insulator (15) that is formed as a casing base.

Abstract: A latch needle (1) has a latch spring (19), which assumes the width of the latch slit (5) in the vicinity of the latch seating (18). However, the latch spring (19) is embodied to be narrower on both sides of this section (25). By means of this, premature wear of the latch or spring in the area of the latch seating device (18) is counteracted on the one hand as is, on the other, the obstruction of the latch slit (5) by dust or dirt. The narrower sections (26, 27) of the latch spring (19) define a passage together with the inner face (8, 9) of the slit walls (6, 7), through which foreign bodies, such as fiber remnants, dust or the like can be conveyed from the upper needle side (11) in the direction toward the needle back (12). In contrast to conventional latch needles, needles (1) of this type of construction show reduced wear, a reduced susceptibility to becoming soiled, and therefore increased dependability.

Abstract: An oil scraper piston ring includes an inner circumferential surface; an outer circumferential surface adapted to contact and slide along an inner wall of an engine cylinder; a radial wall thickness defined by a radial distance between the inner and outer circumferential surfaces; and a plurality of circumferentially distributed recesses each extending radially from the inner circumferential surface toward the outer circumferential surface to reduce the radial wall thickness. Each recess has a first recess region open at the inner circumferential surface and extending radially toward the outer circumferential surface and a second recess region merging into the first recess region. The two recess regions have different shapes, and the area of the second recess region is larger than the area of the first recess region.

Abstract: A filter rod making machine wherein successive increments of a stream constituting a converted tow of filamentary filter material for tobacco smoke are contacted by a compressing tool which is vibrated at a frequency and/or amplitude sufficient to prevent over-heating of the tool and/or of filaments of filter material, such as acetate fibers. Conversion of the tow into the stream and the wrapping of the compressed stream into a running web of filter paper are carried out in a conventional manner.

Abstract: A system for the needle treatment of a conveyable fiber bat is provided with at least one conveying device having a plurality of needles that can be inserted into and withdrawn from a fiber bat. At least one rotating cylinder is provided to make possible a high needle-treatment speed and a uniform structure of the needle-felted fiber bat. The outside of this rotating cylinder forms a conveying surface for the fiber bat. The needles can pass through the conveying device from the inside toward the outside. The needles penetrate the fiber bat perpendicular to the conveying direction and then withdraw. The outside of the rotating cylinder, the fiber bat, and the needles have a similar speed in the conveying direction during the needle-treatment.

Abstract: A projectile body having a groove-shaped recess (2), in which a guide band (3) is disposed. To permit use of a relatively wide guide band (3), while preventing the band from being destroyed as the projectile body (1) passes through the gun barrel, and preventing significant copper-plating of the barrel, the guide band (3) is assembled from two partial guide bands (5, 6), with the relatively narrow, first partial band (5), which faces the base (7) of the projectile, comprising copper or a copper alloy and providing a seal against the propellant gases acting on the projectile rear under high pressure. The second, considerably wider partial guide band (6) essentially comprises plastic, and includes at least one hollow space (11), which lends it adequate deformation reserves with respect to the high surface pressure acting on this partial guide band (6) when the projectile body (1) passes through the barrel.

Abstract: A full-caliber projectile having a cylindrical guide region (5) and an ogival projectile tip (7). To improve the stabilization of the projectile (1) inside a gun barrel (2) in a simple manner, and therefore improve the intermediate ballistics and hit accuracy over those of comparable projectiles, a guide ring (8), which is segmented in the circumferential direction, and whose outer diameter is smaller than the inner diameter of a gun barrel (2) of the same caliber, is secured to the projectile tip (7) such that the radially spaced guide-ring segments (9) detach from the projectile (1) in the gun barrel (2) when a predetermined firing acceleration occurs in the gun barrel, and the segments (9) are pushed toward the projectile (1), axially relative to the cylindrical guide region (5), by dynamic pressure until they rest against the inside wall (18) of the gun barrel (2) and against the projectile (1).
