Abstract: ABSTRACT OF THE DISCLOSURE Calcium hypochlorite particles and larger sodium chloride crystals are separated by passing an aqueous slurry containing such particles and crystals into a first classification zone  comprising a two-stage substan-tially vertical elutriator-classifier.  A first slurry in which the solid phase is predominantly calcium hypochlorite particles is removed from the upper stage of the first classification zone.  A second slurry in which the solid phase is predominantly sodium chloride crystals is removed from the lower stage of the first classification zone and forwarded to a second classification zone comprising a two-stage substantially vertical elutriator-classifier.  A slurry in which the solid phase is predominantly calcium hypochlorite particles is removed from the upper stage of the second classification zone and, in one embodiment,  combined with overflow from the upper stage of the first classification zone.  A slurry in which the solid phase is predominantly sodium chloride crystals is removed from the lower stage of the second classification zone.  Elutriation fluid comprising a saturated solution of calcium hypochlorite and sodium chloride is introduced into the lower stages of each of the first and second classification zones.

Abstract: ABSTRACT OF THE DISCLOSURE           There is described a manually operable puzzle game intended to provide an orderly arrangement of a plurality of pegs.  The game comprises a base, a playing surface being provided above the base, the playing surface comprising a plurality of rows and a plurality of columns which are trans-verse with respect to the rows.  Each row and each column provides a plurality of positions so that one position corresponds to one specific row and one specific column.          There is a plurality of movable pegs which are each intended to occupy one of the positions.  Each peg carries identifica-tion means such as a figure, a letter, or a specific colour, intended to provide an orderly arrangement of the pegs by properly aligning them on the rows and columns of the playing surface.  A frame is mounted above the base to define the outer boundaries of the playing surface.  A pusher member is provided to abut a peg at one end of a row and to enable to push the peg against the remaining pegs in the same row until all the pegs of that row have been displaced to the next position and the peg at the other end of the row enters underneath the frame.  A displacing member enables to move the pegs of a column by one position without disturbing the relative arrangement of the pegs in that column.  The pegs occupying the positions in the column bordering the frame are insertable underneath the frame.  With this game, it is possible to arrange the pegs in a large degree of confusion which means that difficulties arise when trying to re-arrange them in a proper order.

Abstract: - Abstract -The device for sectional monitoring by technical measu-ring instruments the control of humidifying agents within the inking system of an offset printing machine comprises a measuring drum (3) adjusted to a printing paste feeding roller (1) and comprising a partly oleophile, partly hydro-phile surface. In order to precisely establish the partial variations of the humidifying agent contents of the prin-ting paste across the full width of the machine, at least the oleophile surface areas are designed as screens (4) which guarantees both in longitudinal and in circumferen-tial direction of the measuring drum (3) A uniform zonal coverage of an optional zonal coverage degree. During the printing process, the oleophile screen (4) takes up prin-ting paste, whereas the hydrophile surface areas (5) re-main free from printing paste. An opto-electronical measu-ring device (6) is used to continuously measure the zonal coverage and/or its variation on the oleophile screen (4), the measuring results being either shown on a subsequent indicating device (9) or directly used for an immediate approach to zonal positioning elements of a humidifying system. For the purpose of increasing the measuring sen-sitivity, the oleophile screen (4) can either present, in circumferential direction of the measuring drum (3), a uniformely graded surface coverage with at least two different surface coverage degress or be preferently de-signed as a continuously proceeding screen wedge (10), providing for a continuous decrease from 100% to 0% of the surface coverage (see figure 1).

Abstract: ABSTRACT OF THE DISCLOSURE            A  control  system is provided  for  allowing  complex shapes  to  be machined on a workpiece at high  speed. The control system is computer controlled and receives workpiece  profile  data which are  converted  into  a succession  of tool position signals during machining. Not  all the   digital signals are calculated  at  one time, a   number  of  future  digital  signals   are calculated during a succession of time intervals.   In each   time  interval,   a  tool  position  signal  is outputted   which   is   of   a   constant   amplitude corresponding  to  the required    tool  position  and which  is fed  to  a signal  processor  where  it  is converted  into a   continuous signal which so changes progressively that at successive time intervals, equal to  the time intervals of the tool  position  signals, the amplitude of the continuous   signal is related to the  successive  values of the tool position  signals. This  continuous  signal  is fed  to  a    closed-loop control system which controls the movement of the tool holder in accordance with the continuous signal.   The tool  holder is of a type having a bandwidth sufficient  to  allow  the required movements  at  the required speed.  The control system has   proportional and differential feedback.

Abstract: DEFLECTION MEMBER     ABSTRACT       Foraminous members useful in making paper webs. The foraminous member of this invention has a macroscopically monoplanar, patterned, continuous network surface which serves to define within the member a plurality of discrete, isolated, deflection conduits. A foraminous woven element, such as a screen, is thoroughly coated with liquid photosensitive resin to a controlled depth above the upper surface of the woven element. A mask or a negative having opaque and transparent regions which define the pattern is brought into contact with the surface of the liquid photosensitive resin and the resin is exposed to light of an activating wavelength through the mask. The resin exposed to the activating light is hardened (cured). Uncured resin is removed from the composite leaving behind the woven element with the solid network formed by the cured resin.

Abstract: Apparatus and process for supervising and controlling the operations of loading and unloading of fuel of a nuclear reactor comprising an information processor 30 formed from several units. A treatment unit 31 receives control signals giving notably the position, the speed, the load of machines 7 and 16 operating the loadings and unloadings of groups in the core 2, the reactor pool 3, and the spent fuel pit 14. A programmable unit 34 furnishes command signals, previously recorded, representing the loading sequence. The command and control signals are treated in a central calculating unit 35 which, while considering the information furnished by the permanent memory unit 32 and by the temporary memory unit 33 gives on one hand the coordinates of all sites for the groups, and on the other hand the coordinates of the places of the movable elements as well as the identification marks and positions of each group, compares the different signals received, and according to their coincidence, authorizes or arrests the directed movement. The temporary memory unit 33 saves the last position acquired while erasing the previously occupied positions, while the control box 37 records all of the movements executed.

Abstract: Abstract of the Invention A pattern recognition system has both coarse and fine levels of analysis in which a coarse array representation of a workpiece pattern is formed and used to identify the workpiece pattern as either a reference character or as a member of an ambiguous set of reference characters which are represented by identical coarse array representations.  At least portions of a fine array representation of a workpiece pattern which has been classified as a member ofa set of reference characters are compared to corresponding portions of fine array representations of reference characters in the set identified by the classification.  The pattern recognition system has a learning system through which reference characters may be introduced into the recognition system and through which a representation of a workpiece pattern which was not identified may be incorporated into an existing set of reference characters of the recognition system.
