Patent NL-7207258-A (NL)
Title: Yarn fault detector - eliminating discrepancies from self-established norms
IPC: B65H63/06
Filed: 1972-05-29
Abstract: A metering head with a built-in electro-magnetic shear for the detection of faults in textile yarns and their removal, senses the yarn and generates a signal which is processed in wo ways. One circuit treats the signal as a continuous series of items of information whilst the other uses it to represent the average diametric or mass value of the yarn over a length of several metres. Only when the value of a variation in the yarn at a partic. point exceeds the av. value of the length of the yarn of which it is a part, by a preadjusted tolerance, is the shear operated.

Title: Building heating and cooling system - has heating and cooling circuits coupled to heat energy storage reservoirs defining elongate water flow path
IPC: F24D11/00
Filed: 1976-09-10
Abstract: The system includes a heating circuit and a cooling circuit. The circuits are coupled to heat energy storage reservoirs.

Title: Burglar protection system - has fibre=optic conductors in walls, ceilings and floors with light source and detectors to detect penetration, and CCTV camera
IPC: G08B13/12
Filed: 1981-10-09
Abstract: The system detects any attempts to penetrate into the spaces concerned. It uses glass fibre light conductors which are fitted to specific walls, floors and ceilings in a predetermined pattern. One end of the glass fibre light conductors is coupled with a light emitting source and the other end coupled to a light sensitive detector. Penetration of the enclosed area, with consequent breaking of the fibre-optic link, actuates an alarm. The glass fibre light conductors (21) are divided into sections and embedded in the wall panels. The sections of the different panels are coupled to form a single conductor. A closed-circuit TV camera is also provided, its video output being fed down the optical fibre by modulation of the light beam. Two fibres, following differing paths, carry the video signals.
Patent NL-8201624-A (NL)
Title: Triac dimmer circuit for street lighting - saves power and avoids long dark stretches if lamp fails using remote control wire
IPC: H05B41/392
Filed: 1982-04-19
Abstract: The dimmer circuit has a triac in series with the street light's discharge lamp. The triac's gate is controlled from a control circuit that has a control wire for remote control. The output of the control circuit (2) is connected via a feedback circuit (5) to a comparator where it is compared with a signal carried by the control wire. The comparator's output is connected to the control circuit. Each street light has its own triac and control circuit. The advantage lies in saving energy late at night whilst at the same time avoiding the need to switch off, e.g. alternate street lamps and creating dark unlit stretches of road if a light should fail. Dimming all lights saves the same power but avoids long dark stretches if a light fails.

Patent NL-8400629-A (NL)
IPC: G11B20/18
Filed: 1984-02-29
Abstract: A decoding device for code words which are protected against the occurrence of several symbol errors per code word by means of a Reed-Solomon code is provided with a word buffer which comprises a space for the storage of an erasure indication per symbol received. For correction of the code word, first the syndrome symbols are formed by multiplication by the parity check matrix. The sum of twice the number of error symbols and once the number of erasure symbols may not be larger than the number of syndrome symbols. First the syndrome symbols are modified so that the syndrome symbols which could possibly relate to error symbols (non-erasure symbols) are no longer influenced by the erasure symbols. The key equation and error locator equation for the non-influenced syndrome symbols can then be separately solved, so that the locations of error symbols can be found. The latter syndrome symbols are then modified, when necessary, for calculated error locations, while the error values or erasure values are determined from a set of mutually independent syndrome symbols whose numer equals the sum of error symbols and erasure symbols. There is provided an arithmetic unit for the Galois-field which, for the sake of simplicity, performs the calculations on the exponents of the symbols which are written as powers of the basic symbol of the Galois-field.

Title: Night sight with illuminated target cross-wires - controls brightness of LED according to intensity of target image
IPC: H01J29/98
Filed: 1985-11-05
Abstract: A d.c. supply from a battery (1) is fed via an inverter (2) and transformer (3) to a voltage multiplier (4). The multiplier (4) which has a few nano-Amps at a voltage of several kV, is a cascaded circuit of diodes and capacitors.

Patent NL-9200279-A (NL)
IPC: H04M3/00
Filed: 1992-02-14
Abstract: Known methods of detecting routing loops in telecommunication networks are cumbersome and time-consuming. In addition, the probability that an existing routing loop is even actually detected is too low. In a method of detecting a routing loop according to the invention, paths whose lengths are stored are assembled. As soon as the length of a (partly assembled) path exceeds a predetermined value which is greater than, or equal to, the largest existing path length in the telecommunication network, this indicates the existence of a routing loop. <IMAGE>
