Abstract: A laminar article (14) is held in a planar configuration by urging it, for example by means of a vacuum (applied via 16) against a plurality of small-area abutments (18) which define a planar surface. The smallness of the area of the abutments (18) reduces the probability of there being any intervening dirt particles to perturb the planarity of the article (14) and there is a tendency for any such particles to be squeezed out. Preferably the article (14) is given a slight lateral movement after bringing it into contact with the abutments (18) to dislodge remaining intervening dirt particles. The invention is particularly applicable to holding semiconductor wafers during pattern exposure but may be used to hold workpieces during polishing, grinding or machining. <IMAGE>

Abstract: A method of personalizing identification cards having erasable and/or overwritable and non-overwritable data. The neutral identification cards, before being written on, are first fed from an input stack to a unit in which the overwritable storage medium, e.g. a magnetic stripe, is written on with the erasable or overwritable data. After the writing process has been checked, the card is removed from the process if its writing is defective, and possibly reinserted in the input stack. If the writing is in order, however, the card is fed to another unit in which it is provided with the non-erasable or non-overwritable data. Data records are made available by a card-issuing agency in order to personalize the identification cards. One data record is kept on hand in a buffer memory for the writing of each identification card. The buffer memory is only loaded with a new data record after the correct writing on the magnetic stripe has been signalled, while the part of the old data record necessary for writing on the non-overwritable data is transferred to a second memory. A data record is thus only assigned permanently to an identification card when the technically delicate processing steps have been successfully carried out. In this way the reject rate can be kept low at a high throughput. The produced cards are also stacked automatically in the same order as the delivered data records.

Abstract: A method of continuous drying of a paper or other porous web by passing the web (3) by means of a drying felt or wire (4) between two moving, air-impermeable surface elements (1, 8) having good heat conducting properties, which elements enclose the web along its whole width. The surface element (1) contacting the web is heated and the surface element (8) contacting the wire is cooled for evaporating water present in the web and condensing the evaporated water into the felt or wire. The temperature of the liquid used for cooling the surface element to be cooled is maintained above 100 DEG  C. and the pressure at least at such a level as to prevent the liquid from boiling. Thus, the drying of the web can be carried out at an elevated temperature and under an elevated pressure in a continuous process at production conditions for improving the web characteristics. Preferably the cooling liquid is maintained at different temperatures and/or under different pressures at separate steps of the cooling process. Thus, it is possible to adjust the drying conditions affecting the web characteristics. The device for carrying out the method is provided with a cooling space (11) divided into at least two separate cooling liquid compartments positioned one after the other in the direction of movement of the surface elements (1, 8), said compartments containing cooling liquids having different temperatures and/or pressures, the temperature of at least one cooling liquid being above 100 DEG  C.

Abstract: An improved shiftable change speed transmission is provided. The improved transmission is preferably provided with at least one countershaft having countershaft gears thereon disposed in meshing engagement with main shaft gears encircling the transmission main shaft. Gears are selectively axially movable relative to the associated shaft by conventional means for effecting shifting of the transmission. The axially movable gears cooperate with clutch rings which surround and are supported on and for rotation with the associated shaft by splines, preferably the clutch rings also are axially movable relative to the associated shaft and are resiliently urged in a direction toward the respective gear with which same cooperates, whereby shifting of the axially movable gear toward its respective clutch ring causes resilient axial movement of the latter until synchronization is achieved to permit the clutch ring to move axially in response to said resilient urging and engage the main shaft gear. The improvement comprises providing spline teeth on the clutch ring or the associated shaft which are of a substantially constantly varying thickness and are arranged such that, when the clutch rings are in the non-axially displaced position, the circumferential spacing betwen cooperating clutch ring and shaft spline teeth is smaller at the axial end of the clutch ring closest to the gear with which it is associated than at the other end of the clutch ring.
