Abstract: Process and system for broadcasting a high-definition television programme on a channel with capacity below the signal band. The process includes: at the transmission stage, a pseudo-selection of the image dividing the spatial information over n successive frames (n being an integer over 1) and a temporal filter turning down the energy level in the region around f0/n (f0 being the analysis frame frequency) after high-definition coding and before transmission; and at the receiving stage, an interpolation filter and a temporal filter for accentuation corresponding to how far the energy had been turned down before high-definition decoding. The degree of temporal attenuation is adaptable to local spatial activity.

Abstract: This invention relates to a device for transportation and weighing of goods e.g. for checkout desks in shops and stores. Scale tables as used until now occupies space and can be hampering for both operator and customers. Besides the movements which are required for the weighing may cause health problems for the operator. To eliminate these problems the device for conveying and weighing of goods according to the invention has a scale integrated with the conveyors (3,10,11), such that the weighing takes place while the goods is on the conveyor (3). When a weighing shall take place the conveyor (3) is stopped and the weight of the goods is registered whereupon the conveyor (3) is started. The scale device comprises a scale table (1) which signalling device (2) is mounted onto a stand (4) by a holder (8). The conveyor of the scale passes rolls (5,6) which are also mounted onto the scale table (1). The signal from the signalling device (2) which corresponds to the weight of the goods can be treated in different ways and for example in the cash register be combined with information from an index with prices for different kinds of goods. The driving arrangement of the conveyor is controlled by signals from a scanner (9).

IPC: F42B4/26
Filed: 1991-03-30
Abstract: The present invention relates to a flare having a combustible element made from paraffin and a sheath (12) made from paper which serves as wick. Problems have always existed with such flares owing to the fact that the paraffin liquefied by the flame forms copious drops and flows off, as well as that there is a relatively short burning time. The invention provides a remedy here by means of a fire-retarding helix (14) which is laid spirally around the sheathed combustible element so as to produce a spiral interspace (16).

Abstract: The system comprises a coding device (5) equipped with a channel coder (12) and with a modulator (13) and a decoding device (105) equipped with a channel decoder  (112) and a demodulator (113) operating on digital signals transmitted under coded modulation. On coding, a channel coder (12) operates a code concatenation in order to distribute a binary redundancy of a protection coding over several symbol-periods of the coded modulation. The channel coder comprises an internal coder which performs a convolutive coding combined with the coded modulation. The binary redundancy is distributed over the internal and external concatenated codings. A source coder (11) can operate a reduction in the input binary data throughput. In order, on detection, to ensure the rotational invariance of the code, it is possible, on coding, to append a differential coder (31). 
<??>On reception the decoding device (105) performs the corresponding inverse operations. The invention can be used to code/decode digital signals which are to be transmitted/have been transmitted. 
<??>Applications: television, radiowave beams, mobile-radios, storage on compact disc or on digital video recorder, communication between processors.
