Abstract: ABSTRACT OF THE DISCLOSURE      A display surface for presenting information in tactile form by means of a grid-shaped array of tactile elements is disclosed It can be selectively caused to project into the space above the display  surface  by  using lifting  elements.  According to the invention, there are a number of line slides (8) corresponding to the number of lines of tactile dots, and a number of column slides (3) corresponding to the number of columns of tactile dots. On the line slides a part (9) is allocated to each lifting element (7) in such a way that the lifting element is fixed in the plane of the line, although it is movable in the plane of the column. Similarly on the column slides a part (4) is associated with each lifting element to shift the latter in the plane of the column. In a first step,  the position of the tactile elements in each grid line is controlled  by  shifting  the  line  slide  carrying  the  lifting elements in a direction parallel to the grid line so that all the lifting elements in this line are positioned in such a way that they are engaged by the column slide, which is movably located in the interspaces between the grid columns, while this slide is in its middle position.  In a second step,  each lifting element is positioned in one of two possible positions (7a, 7b) on the line slide, by moving the associated column slide. Finally, in a third step,  the line slide is moved.  Depending on their position,  the lifting elements are either moved into the space below the tactile elements, thereby raising them (7c), or they move into the spaces alongside the tactile elements without raising them (7b).

The uranous solution and  the  hydrofluoric  acid solution are introduced into the tank from  the  upper  part thereof and the produced uranium tetrafluoride crystals  are withdrawn from the lower part of the tank  together  with  a part of the reaction  mother liquor.   The  amount  of  the hydrofluoric acid solution added to the uranous solution  is adjusted so that the fluorine concentration in the  reaction mother liquor in the tank is maintained at 2 to 4 g/l.

Abstract: The present invention relates to a procatalyst composition for the polymerization of alpha-olefines, which has been prepared in steps, in which is arranged a carrier agent based on at least one inorganic oxide, having few or no hydroxyl groups on its surface, and the carier agent is reacted with the magnesium compound and one or more transition metal compounds of the groups IVB and VB of the periodic table. It has been observed that such a catalyst is most-advantageous when a) this carrier agent is impregnated with a mixture of the Mg compound and one or more compounds of a transition metal of the groups IVb or Vb of the periodic table, which dissolves the Mg compound, and b) by chlorinating with a compound that does not contain titanium so that 1) the carrier is first treated with a mixture in the form of a solution of the Mg compound and the transition metal compound and the product thus obtained is chlorinated, or 2) the carrier is first chlorinated and subsequently treated with the above mixture in the form of a solution, or 3) the Mg compound and the transition metal compound are impregnated into the carrier without any separate dissolving and the product thus obtained is chlorinated.

Abstract: A method of providing ventilation for a processing space (1) with an access opening (3) from the surroundings, the space being separated from the surroundings by blowing treated supply air (A) into it to form an air curtain (5) at the opening in order to prevent the entrance of surrounding air. To enable an efficient separation of the space even with a great temperature difference between the supply air and the surrounding air, the supply air is blown to form a free circulation flow (A') in the space. The direction of the circulation flow at the opening is opposite to the direction of convection flows (B) of surrounding air created by the temperature difference, and the flow rate at the opening is greater than that of the convection flows. In an equipment for realizing the method, devices (6, 7) for introducing supply air are mounted to create a free circulation flow (A') in the processing space (1), forming an air curtain at the opening. <IMAGE>
