Abstract: A mould oscillator for a continuous casting machine comprises at least two tensile elements (46, 48, 50) disposed so as to always remain in tension. The tensile elements (46, 48, 50) lie on respective radii extending from the radius of curvature of the casting radius R and are anchored to a fixed external frame (40, 42, 44). The oscillating drive (90) is in the form of a cam (104) which moves a follower (108) pivoted at one end. A transfer element (124) between the follower (108) and the mould (20) transmits the oscillation to the mould (20) and the oscillation stroke is varied by adjustment means (142) changing the distance of the cam (104) from the pivoted end of the follower (108).

Abstract: The driving apparatus for the spindle of an electro erosive machining apparatus comprises an electric motor adapted to be operated to rotate in two opposite directions and a reduction gear box assembly operatively coupled to the electric motor. The gear assembly is provided with a pinion and two gear wheels which are rotatable with reference to each other. Both gear wheels mesh with the pinion. One of the gear wheels is under the influence of a torsional biasing force. A first of the gear wheels is torsionally fixedly connected to the spindle of the electro erosive machining apparatus, while the second gear wheel is rotatable with reference to the spindle. Such a driving apparatus operates with low expenditure without backlash in both senses of rotation whereby an eventually occurring wear is automatically compensated.

Abstract: Computer-processed or computer-generated objects can be used to build holograms (10) whose images are close to or stradddle the hologram surface (10). No preliminary or first hologram is required. The hologram (10) is built up from a number of contiguous, small elemental pieces (12).    Unorthodox views from inside the object (30) are required for the creation of these elements (12). One method of gen-erating the views employs unique object manipulations. The computational transformations ensure that no singularities arise and that more or less conventional modeling and ren-dering routines can be used. With a second method, a multi-plicity of conventional object views are collected. Then all pixels (22) in these conventional viewplanes (20) are reas-signed to new and different locations in the new viewplanes (20) for the element views (22). These methods may be used to build rainbow holograms or full parallax holograms.    When properly executed they are visually indistinguishable from other types.

Abstract: A twin-wire former of a paper machine, for high speed paper machines whose web running speed is of an order of from about 1600 m/min to about 2500 m/min.  The former includes a carrying wire guided in a loop and a covering wire guided in a loop to define a twin-wire zone and an inlet or forming gap between the wires.  A pulp suspension layer or a pulp suspension jet is fed into the inlet or forming gap through a discharge duct of a headbox.  The former also includes, as a combination, a first forming-suction roll arranged proximate the forming gap in a loop of one of the wires and a second forming-suction roll arranged inside the loop of the wire opposite to the wire inside whose loop the first forming roll is arranged.  The forming-suction rolls have suction zones over which the twin-wire zone is curved on certain sectors.  In the suction  zones,  the  vacuum  levels  are  arranged  adjustable independently  from one another,  and possibly relative to one another, so as to minimize the unequalsidedness of the web.
