Title: Laser image exposure of lithographic printing element
Inventor: CHATTERJEE DILIP K
IPC: B41C1/10
Filed: 1998-04-02
Abstract: An imaging process involves (a) preparing a lithographic printing element having a printing face of a zirconium oxide ceramic which is alloyed with one or more of MgO, CaO, Y2O3, Sc2O3 and rare earth oxides as secondary oxide and which has 5.6-6.2 g/cm<3> density; and (b) producing an image on the printing face by image-selective exposure to laser radiation at 0.1-50 W average power, 6000-100000 W peak power, up to 50 kHz pulse rate and 50-500  mu s average pulse width. The laser radiation melts the zirconium oxide in the exposed regions and converts the printing face from a hydrophilic state to an oleophilic state or vice-versa, thus forming a lithographic printing face with image and non-image regions.  Also claimed is a lithographic printing process including the above imaging process.

Patent DE-19845764-A1 (DE)
Inventor: BLUMENSTOCK WERNER
IPC: G06F11/14
Filed: 1998-10-05
Abstract: The invention relates to a programmable controller for use especially in a larger automation installation and to a method for operating a programmable controller (S1..Sn). The programmable controllers (S1..Sn) are linked to a central computer (R) of the automation system via a network (2). All of the user data (3), user programmes (4), configuration data (5) and the operating systems (6) of the programmable controllers (S1..Sn) are stored on the central computer. Only working copies of these data are stored in the programmable controller (S1..Sn). In particular, in the event that the components of the programmable controller (S1..Sn) fail, the user data (3), user programmes (4), configuration data (5) and/or the operating system (6) are loaded from the central computer (R) via the network (2). This enables the operating system to be updated very simply and centrally. The current versions of the user programmes are also centrally available and are therefore easy to archive. Finally, the necessary data can also be loaded automatically at any time in the event of a malfunction.

Title: Vanishing door or window hinge uses hinge link in two parts fixed one end to door or window and at far end foldably joined to form hinge joint.
Inventor: FISCHER CHRISTIAN
IPC: E05D11/06
Filed: 1999-01-18
Abstract: One end of the two parts (7.1,7.2) of the hinge link (7) is fixed to door or casement and otherwise foldably joined together at their far end to form a joint (13). Each hinge link part (7.1,7.2) is fitted with a holder (14,15) to set up a magnetic force which moves the two parts relatively when the hinge folds open when loaded by less than the introduced torsion limit. The holders (14,15) form permanent magnets which so lie flush in the opposing hinge part walls within the joint range that the hinge links have unlike poles facing when folded shut. The magnets are in cylinder form sharing a common supporting axis and the first hinge link part (7.1) fixed on one side to the door case frame is pivotally joined by shaft to the second link part (7.2) acting as door or window casement holder. A distance piece on the swivel shaft between the two hinge link parts serves as pressure bearing. A second holding magnet (20) in the first link part (7.1) and a third magnet (18) in the hinge recess (16) of the frame sets up maximum holding force so hinge link and case frame make contact in the 110 deg  opening setting of door or window casement (4).
