    Abstract: In an automatic sewing machine for sewing bands onto fabric parts, a metering device (3) which meters the band is electronically coupled to the sewing machine via a position sensor (6) in the form of a pulse generator, a signal processing circuit (8) and a motor, for example a stepping motor (SM). The amount of band per unit time delivered by the metering device depends on the speed. On the other hand, the stitch length of the sewing machine is, however, not independent of the speed but becomes greater with increasing speed. The resulting, undesired tensions between the fabric part on the one hand and the band on the other hand are avoided by a correction means (10) between the pulse generator (6) and the sewing machine (2) and the driver circuit (12) of the stepping motor (SM) of the metering device (3). The correction device ensures that control signals reaching the driver circuit (12) result in corrected, excessive metering of the band at higher sewing machine speeds. This correction is possible not only in the case of bands but generally for elements which, depending on the speed of the machine drive, are transported relative to the pressure foot.

    Abstract: During ceramic casting for the production of a molten bath it is often observed that the fire-resistant material becomes eroded and/or solid oxide phases are deposited. Both phenomena interfere with the smooth outflow of the molten bath. The present invention is intended, therefore, to provide an outflow which is stable in shape even when a molten bath is passed through, especially in multiple-sequence casting. To this end, the invention provides for ceramic casting with an envelope (10, 14) which is at least partly external and an internal insert (11, 14, 53) at a distance from the envelope (10, 14), the insert ( b 11, 14, 53) and envelope being connected together.

    Abstract: The invention relates to a charge retaining mechanism for retaining a charge inside a chamber of a barrel of a gun, comprising retaining members consisting of a central retaining member and two sets of end retaining members, extending from an elongate coil spring, into the chamber. The coil spring is located in an elongate groove formation cut into the inner surface of the barrel and extending partially around the inner circumference of the barrel. The charge retaining members are movable between a charge passing position and a charge retaining position and are biased in the direction of the charge retaining position by means of the coil spring.

    Abstract: A compact and re-usable ingate device for transferring molten metal to a mold during casting employs a substantially unitary structure resembling a trapezoidal block of refractory material. Within the block are a generally cylindrical rotation chamber, an inlet channel which receives the molten metal and injects it tangentially into the rotation chamber, so that the metal swirls rapidly to separate nonmetallic inclusions, and an outlet channel which conveys the cleaned metal to the mold. The rotation chamber may have a bottom that is positioned below the opening to the outlet channel and walls which slope outward slightly from the bottom to at least the opening, so that inclusions and metal that has solidified at the bottom can be removed from the rotation chamber. Alternately the outlet channel may open into the bottom at an eccentric position, so that all of the molten metal will be drained.

    Abstract: This invention relates to a breech assembly of a gun adapted to fire caseless charges, ignited and enhanced with electrothermal chemical (ETC) charges. The gun utilises charges as propellant and a plasma generator cartridge (PGC) for generating plasma when an electrical current is applied thereto. The breech assembly comprises a breech ring, a tilting block assembly, with a spindle installed and a sliding block for supporting or locking the tilting block assembly in a sealed position. The tilting block assembly is movable between a PGC firing orientation and a PGC loading/removal orientation. The breech assembly further includes a crank means, which includes a guide means for rotating the tilting block assembly from the PGC firing orientation to the PGC loading/removal orientation.
