Patent NL-8200560-A (NL)
IPC: H04W88/18
Filed: 1982-02-15
Abstract: A description is given of a system for communication between a transmitting station (30) and a receiving station (33) by way of a message which consists of a direct succession of a number of identical code words. Each message uses only a comparatively small part of the capacity of the message channel. Each code word has at least a predetermined minimum Hamming distance with respect to any other code word, including the cyclic transpositions of the latter code word. Therefore, for the detection and reproduction of a code word it is not necessary to realize word synchronization and a given category of errors can still be detected and/or corrected. The code words may concern, for example, a transmitter or program identification in a broadcasting system or a paging code for a receiving station in a system comprising selectively addressable receiving stations as in a paging system.

The current is directed at the top ovetr aover a surface curving upwards, while the nozzle is movable over the layer. The nozzle is moved to and fro in a plane at a predetermined distance above and parallel to the topmost layer. The current is cut in as the nozzle leaves the starting position, and out again on the return before reacing this position.
Patent NL-9000004-A (NL)
IPC: C02F1/48
Filed: 1990-01-02
Abstract: A method is described according to which particles present in a fluid are separated from flakes adhered thereto. According to prior art separation takes place with the help of an ultrasonic field applied to the fluid. It appeared that a better separation is achieved, if the flakes are subjected to a substantial velocity gradient. This velocity gradient subjects the particles to shearing forces causing an effective separation of the elements. Tests have shown that a pump generates such velocity gradients, that a most effective separation is achieved. <IMAGE>

Title: Locking system with tumbler and key - has magnets in key and tumbler placed to provide fluxes at right angles in key and tumbler when operated
IPC: E05B47/00
Filed: 1991-04-08
Abstract: Locking system for sue with individual keys on a group or centrallised basis is based on a spring loaded tumbler (4) and magnet (5, 6) rotating in an encased (1) cylinder barrel (2) so as to drop into slots (3) in response to key action (7) when its magnets (8, 9) cooperate with those in the tumbler. The magnet flux of the magnet(s) in the key flows at right angles to that between the magnets in the tumbler. When the tumbler is in the down or locked condition, with the key inserted, the centre line between the magnet fluxes in the tumbler lies between the outer ends of the magnets incorporated in the key. If the tumbler has two or magnets viewed in the movement direction of the tumbler the magnets placed in a nonmagnetic part of the tumbler, the key should also have magnets to cooperate with these.

Patent NL-9200436-A (NL)
IPC: H04B10/07
Filed: 1992-03-09
Abstract: Method for determining fault locations in a local optical network. In the case of a fibre failure arising, a measuring signal is fed to the network, the reaction of the network to said measuring signal being analysed and converted into a location indication of said fibre failure. The output signal of the optical light source, in addition to the normal signal, is also modulated by the measuring signal. The measuring signal is preferably an OFDR signal, a signal having a frequency which varies according to a defined pattern. The signal reflected at the location of the fibre failure is converted into an electrical reflection signal. Said reflection signal is compared with the original measuring signal and, by means of frequency analysis of the two signals, the location of the fibre failure is calculated. <IMAGE>

Title: Method for reducing the number of column voltage levels in multi-line selection multiplex activation of dot matrix liquid crystal display devices
IPC: G09G3/36
Filed: 1993-01-27
Abstract: In a liquid crystal display device with a matrix structure, a plurality of lines are simultaneously selected during the periodic scanning of the line electrodes. The number of voltage levels of the column voltage signals to be provided is selected in the 2 < n1 < n1 + 1 range, where n1 represents the number of lines which are to be simultaneously selected. The resulting 'ON'/'OFF' selection ratio, with an appropriate selection of the amplitudes of the line selection voltages and the column voltages, differs only slightly from the optimum Alt & Pleshko selection ratio which is derived in the case where n1 + 1 column voltage levels are used. To obtain a higher 'address duty', the line selection voltage signals can be split up into a number of distinct voltage signals which are distributed over the scanning period and added to the lines concerned; the associated column voltage signals are split up in a corresponding manner.
Patent NL-9302026-A (NL)
Title: Hull structure for ships and other vessels
IPC: B63B1/04
Filed: 1993-11-23
Abstract: When sailing, heavy ships all have to deal with continuously pushing the barricading mass of water sideways according to the speed, etc., which sometimes causes water to touch the banks, which constitutes a considerable force which is wasted to no effect. The object of the invention is to provide a ship which sails more over the water than through it, by halving the draught, together with a bow surface which runs smoothly upwards, protected by side walls which also project below the base, and, at sailing speed, presses water and counter-pressure below the base, so that there is less counter-pressure and therefore less force is required. This provides considerable differences and advantages. In the case of relatively light vessels, no widening is required, and with this principle these vessels at speed move entirely over the water; it will be possible to form a layer of air which maintains an upwards pressure due to the side walls remaining in the water, even downstream of these walls, which prevents the known phenomenon of falling backwards and can be trimmed by elevation. According to this invention, speedboats and extra-quick ships can sail at full speed.
