Abstract: Pairs of level sensing devices (I₁, I₂) are used in a method that aligns plane surfaces (13,15) to one another. One of the pairs of level sensing devices is located on each of the plane surfaces, respectively. The level sensing devices (I₁ I₂) of each pair are aligned and positioned parallel to two orthogonal axes of the plane. The output signals from corresponding ones of the pairs are differentially compared, and one of the platforms adjusted in pitch and roll to minimize the values produced by the differential comparison. The platforms are then tilted equal amounts and adjusted in azimuth.

Abstract: A wet fabric (18) is felt calendered by passing it in a suc­cession and alternately over a plurality of rollers be­longing to a first order and to a second order. An annular felt band (9) recirculating at the same speed of the fabric is maintained in contact with the fabric during the passage of the fabric over the external surface of the heated man­tle of the rollers belonging to one of said two orders (3,5,7) and the felt further embraces an additional heated drying rol­ler (8) before recirculating again on the series of rollers of said order. Alternately, e.g. between a roller embraced by the felt and the next one, the fabric travels on a roller belonging to the other order of rollers, which may also be optionally heated, without being sandwiched thereon by the recirculating felt. The temperature of each roller is sepa­rately adjustable in order to optimize the treatment con­ditions of the fabric, notably temperature and humidity, though being restrained to maintain a dictated speed of the fabric. The finishing characteristics which are obtained and the energy efficiency of the drying process are im­proved in respect to the prior art. A felt calender with these characteristics is also disclosed.

Abstract: A drive circuit for a stepping motor used for seeking the reading/writing head of a floppy disk or the like. The stepping motor is smoothly driven by inserting an inner step pulse between the input step pulses when excitation signals are supplied to the stepping motor on the basis of the step pulses from the host computer. Since the interval between the step pulses output from the host computer is different each time, the interval between the step pulses is measured and the timing for generating an inner step pulse is deter­mined on the basis of the measured value.

Abstract: The invention relates to a system for driving the knife arrangements of an open-shed double-lift jacquard machine, which is built completely above the machine and which consists of a central driving axle (1) driving, at the two outer ends, a set of complementary cam discs (3) which interact respectively with two guide levers (4) located diametrically opposite one another. These execute relative to one another a to-and-fro pivoting movement between their arms (6) in phase opposition about a transverse axis of symmetry. By means of each pair of guide levers (4), two knife suspension bars (12) are so connected to those arms (6) via driving rods (11) that they move up and down relative to one another in phase opposition in vertical parallel surfaces. A number of knives (25) are suspended in the insertion or weft direction on two respective knife suspension bars (12) which move in phase and which are located on the opposite sides of the machine in the warp direction. Auxiliary means are provided for adjusting the stroke and inclination of the knife suspension bars (12).

Abstract: The security pattern printed on a security paper is composed of a basic pattern on one side, having parallel lines (10, 20, 30) running in a specific direction with a multiplicity of interruptions, through which regions in the form of letters are cut out, and of a multiplicity of linear portions (1, 11, 21) which fill said regions. A plurality of groups (R to Z) of adjacent letters form a word in each case. Inside each group, all linear portions are parallel to one another, but from word to word the directions of the respective linear portions differ so that there is a multiplicity of words with differently sloping linear portions. Adjacent successive lines of the basic pattern and adjacent successive linear portions have alternately different colours, three different colours preferably being represented. In an attempt to reproduce a security paper with such a multi-coloured security pattern by means of a colour copier, the linear portions crossing the scanning direction at a greater angle, primarily approximately at a right angle, are reproduced more widely and diffusely than the linear portions and lines running approximately in the scanning direction so that, as a result of the widening of these lines, the corresponding words become clearly visible which are not noticeable in the security pattern of the genuine security paper when viewed briefly.
