Abstract: Digital filter for filtering non-uniformly quantised pulse code modulated signals formed by a sequence of code groups x(i), each comprising a polarity bit, a segment number and a mantissa number. This digital filter arrangement comprises a generator which cyclically generates a series of sequentially occurring auxiliary numbers each comprising a polarity bit and an address code; a first storage medium 1 for storing the code groups x(i) and controlled by an address computation circuit 13 to which the auxiliary numbers are applied; a second addressable storage medium 2 to which a segment number s(i-h) a mantissa number m(i-l), supplied by the first storage medium 1, as well as a polarity bit supplied by an exclusive OR-gate 3 are applied as the address code. This polarity bit is derived by gate 3 from the polarity bit p(i-l) of the code groups x(i) and the auxiliary numbers polarity bit. This second storage medium 2 contains positive numbers zp and negative numbers zn which represent the expanded values of all possible code groups x(i). A positive number zp is read from the storage medium 2 if the polarity bit is positive and a negative number is the polarity bit is negative. The numbers read from the storage medium 2 are applied to an accumulator 4 which is coupled to an address code output of the generator 7.

Abstract: A method and apparatus for applying newsprint ink and dampening fluid to a lithographic printing plate (112), the apparatus comprising an ink metering roller (12) in rolling pressure indented relation with a transfer roller (10) having an oleophillic surface and a dampening fluid transfer roller (210) having a hydrophillic surface each of the transfer rollers being driven by a reversible variable speed motor (69, 269). The transfer rollers (10, 210) are in pressure indented relationship with a form roller (90) which transfers a thin film of ink and dampening fluid to the printing plate (112). An excess of ink is supplied to the nip between the metering roller (12) and the transfer roller (10) to produce the thin film of ink which may be further conditioned by an ink storage roller (82) prior to entry of the film of ink into the ink transfer nip (106) between the transfer roller (10) and the form roller (90). By controlling the relative speeds between the form roller (90) and the transfer roller (10), slippage occurs which meters a thin film of ink onto the form roller (90) for transfer and application to the printing plate (112).

Abstract: A fluid flow monitor for use in a steam flow line and comprising a chamber (1) in which condensate can collect and a single baffle (5,50) between an inlet (2) and an outlet (3) of this chamber. The baffle is disposed such that a steam flow induced pressure drop at the chamber outlet results in rise in condensate level on the outlet side of the baffle and corresponding fall on the inlet side. The monitor further comprises means for detecting change in condensate level constituted by a single electrode (8) extending into the interior of the chamber, this electrode being electrically insulated from an electrically conductive area (9) exposed to the collected condensate and positioned such that in use change in condensate level to a predetermined extent breaks an electrically conductive path from the electrode via the condensate to the conductive area. The need for sight glasses which are easily dirtied and require skill in use is avoided and the monitor described is of simple construction.

Abstract: A casting mold with a feeder, particularly for producing cast iron, includes an exothermically heated feeder mass. The casting material in the cylindrical or slightly conical feeder volume of the feeder mass is kept in a liquid state until termination of the drawing in of casting material by suction into the casting cavity. The feeder volume has dimensions corresponding to the quantity of casting material drawn into the mold cavity to compensate for casting shrinkage, plus a miximum security allowance of 30 percent of the quantity of casting material drawn in. To obtain a feeder mass which is less costly than conventional feeder masses, from the point of view of simpler and more propitious temperature measurements, the feeder mass has an outside shape of a flattened sphere, a flattened ellipsoid or a flattened pear. The smallest diameter is on the side away from the casting being produced. The flattening is provided adjacent to the casting.

Abstract: A multi-cylinder drying section and method in a paper machine wherein the paper web to be dried is guided into contact with the surfaces of heated drying cylinders wherein the drying fabric is cooled as it travels from one drying cylinder to the next. According to one embodiment, preferably used in the first group or groups of drying cylinders, a single-fabric draw is used wherein the web is supported on the drying fabric as it runs from the cylinders of one line to the cylinders of the other line so that the web is in direct contact with the surfaces of the drying cylinders in one line while the drying fabric is in direct contact with the surfaces of the cylinders in the other line. The drying fabric is cooled as it runs between the cylinders on which the web is in direct contact with the heated surfaces by causing the drying fabric to come into direct contact with a cooling roll or cylinder surface whose contact area is relatively large. In another embodiment wherein the web is conducted through the drying section in a twin-wire draw, i.e., wherein the web travels between the cylinders of the respective lines in an open draw, the drying fabrics come into direct contact with guide rolls which act as cooling members to cool the respective fabrics. The invention provides lower production costs and reduced energy consumption as well as improved machine reliability, a significantly reduced length of the drying section and increased service life of the drying fabrics.

Abstract: The invention relates to a method and an arrangement for finding discontinuities in materials by means of a sensor which is sensitive to the discontinuities in question. According to the invention, the material 1, for example in the form of a web, is scanned by at least two sensors G1, G2 which are made to move, during scanning, over the material web in at least two circular paths RB1, RB2 or the like in a plane essentially parallel to the plane of the material or part thereof, and the centres of rotation P1, P2 of the at least two sensors are arranged so that their centre distance C is smaller than the sum of the radii of rotation or the like of the same sensors, that is to say R1 + R2 > C. In this manner, the sensors will scan the material surface in question so that the surface-scanning patterns formed by the sensors and their movements are adequately fine-meshed and orientated in order that any discontinuities can be found, for example detected and indicated, on the whole irrespective of the orientation and position of the discontinuities on/in the material. <IMAGE>
