Abstract: The method forms a continuous and even layer of material, this being delivered in a regular stream by a distribution mechanism so as to form the layer on a travelling strip. Before delivery to the distribution mechanism the material is formed into an intermediate stream and deposited in strips at  right angles to the travel direction and joined together. The drive can be controlled by a computer accepting input values in the form of  signals for layer thickness or material distribution.

Abstract: In a process and apparatus for producing hollow bodies from plastic material which are at least partially filled with foam, firstly a preform is expanded in a blow molding mold by an increased internal pressure to form a hollow body which is then at least partially filled with foam plastic beads. The compressed beads are introduced into the expanded hollow body while still within the mold, under a pressure which is higher than the pressure obtaining in the hollow body. The beads in the hollow body experience a relief of pressure which results in the increase in volume of the beads and which provides for at least very substantial filling with a foam of at least a delimited part of the volume in the hollow body.

Abstract: The diameter of the bobbin (10) is normally calculated (20) from the speed and diameter of the friction drive drum (13) but during pattern breaking the drum speed is altered momentarily so that slip occurs. To obtain the actual momentary bobbin diameter, the speed value prior to pattern breaking is used to calculate the expected increase in diameter during this period, which is then added on.

Abstract: The invention relates to a screening and/or synthesis device for carrying out at least one basic operation such as adding, releasing, converting, transferring, detecting, on samples that are contained in reaction vessels of a substance support, especially a titer plate, with at least one receiving device that receives the substance support. The invention further relates to a corresponding method. The inventive device is provided with a receiving device that contains a leveling out device that at least partially levels out the substance support before and/or while the basic operation is carried out by subjecting the plate to a pressure and/or attractive force towards a planar area of support. Any bending and/or unevenness that is due to the manufacture of the large-surface titer plate that is preferably used for a simultaneous testing in screening and synthesis systems and that has a multitude of reaction vessels is compensated or removed across the entire base area or at least in partial areas of the titer plate. The inventive device and method improves the functionality, effectiveness and reliability of highly integrated screening and/or synthesis systems since titer plates that are bent due to the manufacture of the plate can be used without problems.

Abstract: The auxiliary jet (8), for the insertion of a weft through the shed of a jet loom, is a hollow needle (11) with a bulge (13) at the point (12). The bulge (13) is aligned towards the reed, when the auxiliary jet (8) is installed in the loom.  The bulge (13) lies at the wall of the hollow needle (11) in a stepless configuration. The bulge (13) has a wall (27) which is aligned with the wall (26) with the outflow opening(s) (25). The interior of the hollow needle (11) is expanded at the bulge (13), and preferably narrows at right angles to it. At least the wall (26) with the outflow openings (25) has an increased thickness. The outflow opening(s) (25) is (are) structured as jets. The point (12) of the hollow needle (11) has a straight upper edge (28), extending to the bulge (13) zone, and is aligned at an angle of 70-110degrees to the longitudinal axis (32) of the hollow needle (11). The highest point (30) of the upper edge (28) is at the bulge (13). When the auxiliary jet (8) is installed in the loom, the upper edge (28) of the point (12) lies along the longitudinal line of the warps, or is at a tangent to a circle round the sley axis. When in position, the upper edge (28) of the auxiliary jet point (12) is close to the lower section of the U-shaped weft insertion channel at the reed. When the auxiliary jet (8) is installed, the bulge (13) is at a gap of not more than 3 mm from the lower section of the U-shaped weft insertion channel.

Abstract: The invention relates to a protecting device for a synchronous motor, for detecting an asynchronous state, caused by a mains disturbance, in which a susceptance (1 DIVIDED X) is determined from the stator current (I) and stator voltage (U), which susceptance activates a trip if a protection characteristic (s;s';t), defined by an adjustable response value ((1 DIVIDED X)e), is exceeded. If the synchronous motor is connected to an approximately constant mains voltage, then the detection of the reactive component (IB) of the stator current (I) or the reactive component (PB) of the power (P) is sufficient. With suitable adjustment of the protecting device with respect to asynchronism and lose of synchronisation as a consequence of mains disturbances, it is also possible to detect faulty under-excitation or loss of excitation of the synchronous motor. <IMAGE>
