Abstract: The object comprises a glass-metal film (1) with a metal matrix (2) which has solidified in an at least partly glass-like form and which may comprise hard particles (3, 3a) in the form of primary precipitates from the molten mass. The glass-metal film (1) is provided on at least one side (4) with a top layer (5) comprising a hard material which is harder than the glass-metal film (1). The top layer (5) may be formed by a base layer (7) with embedded hard material particles (8), e.g. of diamond or cubic boron nitride, or by a homogeneous hard material, e.g. diamond-like carbon. The result is a surface quality which can be separately influenced by the composition of the alloy of the glass-metal film (1). The object may be formed either as a parting tool or as a structural part with special wear and/or sliding properties.

Abstract: A rotor for a series-shed loom is furnished, with relay system jets (3). These relay system jets (3) are located inside the rotor, and are supplied with compressed air by an air distribution system (10) via delivery stations. The delivery stations are distributed in the axial direction in order to produce a travelling field (22) relative to the loom rotor. At the same time, the delivery stations (6) are adjustably mounted in the direction of rotation (41) and are connected to an adjustment device (27, 33). The adjustment device permits the angle of rotation (8) between the delivery apertures (7) of various stations (6) to be adjusted at the broad side of the rotor (1). This also enables the maximum possible weft insertion angle .alpha. with the greatest possible weft insertion velocity to be used even with a reduced loom width (36).

Abstract: A stationary fluid mixer in a flow conduit (7) has at least two baffle plates (10) secured to the wall of the conduit. The baffle plates are wider on the inside of the flow conduit than along the conduit wall, and they form an angle W of 10.degree. to 45.degree. relative to the main flow direction Z. The baffle plates can be given different orientations, and the projection FZ of the baffle plates in the main flow direction through the conduit is between 5.degree. to 30.degree. of the conduit cross-section F. This provides efficient mixing of the fluid in a simple manner.

Abstract: In a selvage laying equipment a catcher nozzle (44) with a catcher channel (45) lying in axial prolongation of the nozzle and a threader nozzle (41) with a catcher channel (42) lying in axial prolongation of the nozzle are arranged in a carrier (54) with the axes of their air jets crossing one another, which enables a narrow construction of the device for threading the end (21a) of the weft yarn into the eye or hook of the selvage laying needle (11) and hence short ends (21a) to the weft yarn and narrow selvages, respectively. Bits of dirt such as fluff are reliably carried away from the gap (55) in the carrier (54) as well as from the catcher channels (42, 45) and the formation of an air dam is prevented.

Abstract: The weaving machine has at least two sectional warp beams (20a, 20b) and at least one whip roll (23) rotatably mounted to the machine. Each sectional warp beam is equipped with an individually drivable warp let-off motion (30, 31, 32). Feeler members (13a, 13b) are mounted symmetrically on a rocker-like bar (10) to measure the warp yarn tension and control devices individually control the speed of rotation of the sectional warp beams. The rotational axis (11) of the bar (10) is parallel to the warp plane and is situated between the sectional warp beams. A sensor (14a) determines the deviation of the bar alignment from a reference position, so that it is possible to effect warp let-off control.

Abstract: The method according to the invention enables thin metal parts (10), in particular metal foil, to be produced from a reactive metal by means of hot forming. The reactive metal is embedded in a capsule (11), which consists of a second, plastically deformable metal, and release agents consisting of powder particles. The parting agents between the capsule wall and the reactive metal are applied in at least two layers (12, 13), preferably as an aqueous dispersion. The powder particles (e.g. boron nitride) of a first layer (13) which is applied to the reactive metal form an essentially more compact packing than the powder particles (e.g. calcium fluoride) of a second layer (12). The release agent of the second layer is plastically deformable or fluid in a highly viscous manner during the hot forming process. The novel method is less expensive than known methods in which the parting agent is applied by a thermal spraying process.

Abstract: A centrally symmetrical fuel cell battery is made of stacked modules each of which has an electrochemical active plate made of one oxide ion conducting solid electrolyte and two electrodes, a gas impervious wall between an air chamber and a fuel chamber, an air conduit from at least one peripheral intake location to a center of the module where the air comes in contact with the electrochemically active plates, and a central supply point for a gaseous fuel. Unlike prior art fuel cell batteries of this type which require seal rings, the fuel cell battery of this application requires no seal rings. The electrochemically active plates are continuous, and supply conduits for the fuel are provided for directing the fuel to each module from at least one intake on the periphery of the module to a central supply point of the module.

Abstract: The mechanism for the acceleration of a projectile of a projectile loom has a torsion-bar launching mechanism (1) with a striker lever (3) which, at its end remote from the torsion bar (2), carries a striker piece (34) which, during launching, acts directly on an impact face (43) of the projectile (4). The projectile (4) for the loom has a casing formed of a hollow body and may be partially closed at the rear, as viewed in the direction of flight. The striker piece (34) can pivot on the striker lever (3) and has at least one striker face (33) which is aligned by an alignment member (5) so that at the instant just prior to triggering of the weft insertion the position of the striker face conforms to that of the impact face (43) of the projectile (4); that is, for example, the two are parallel. The transmitted impact energy is uniformly distributed over the impact face of the projectile (4), which advantageously reduces wear of the striker face ( 33) and impact face (43).
