Abstract: Installation for washing soil 
<??>An installation for washing soil is to be provided in which soil is made into a slurry with water and harmful substances are separated from the soil via the water. The aim of the invention is to reduce the water consumption while at the same time improving the preparation of the soil. 
<??>This object is achieved in that a first screen area (7) and a first base section (10) allocated to this first screen area (7) have arranged upstream of them a second screen area (13) and, arranged upstream of the latter, a further water-feed area (16) having a further water feed (17). The second feed line (17) is fed with the water coming out of the first screen area (7).

Abstract: Apparatus for transmitting data spread across at least a portion of the bandwidth of a cable television channel comprises a carrier signal oscillator, a frequency divider, a pseudorandom sequence generator and two exclusive OR gates. A first exclusive OR gate serves to spread a data signal across the pseudorandom noise sequence generator having a much higher chip rate than the bit rate of the data signal. The second exclusive OR gate modulates the spread spectrum data signal to a carrier frequency for transmission over the cable television channel. The apparatus may be applied for return path transmission in the 0-30 megahertz band which is high susceptible to interference noise and provides approximately a 20 dB signal to interference ratio advantage over known data coding and transmission schemes. A microprocessor normally present in a cable television terminal may format data for transmission, control the spread spectrum modulation process and control gain control circuitry for introducing an appropriate power level into the cable plant.

Abstract: To process picture data, especially for still picture transmission, picture data are in each case transformation-coded by sub-picture areas in a plurality of passes and the coefficients obtained are selected for transmission according to their significance. In each pass, finer quantisation and selection of a larger number of coefficients are carried out. The picture data obtained from each pass of the processing are used to process subsequent pictures if the content of the subsequent pictures has changed only slightly compared with the previously processed picture. The DC coefficients already undergo definitive fine quantisation in the first pass and are not further improved in the subsequent passes. <IMAGE>

Abstract: A method of extracting particulate matter from waste material produced by peeling vegetable products, especially for extracting starch from waste material produced in peeling root vegetables. The waste material including the particulate material is by means of a liquid supplied to a moving filter belt (10) from which liquid containing particulate matter is sucked away. Liquid containing a high percentage of particulate matter and sucked away from the filter belt is recirculated to the filter belt at a location thereof which in the direction of movement of the belt is positioned after the point of the belt where the waste material from the peeling machine is supplied. Thereby, the waste material forms at the filter belt a filter cake for filtering the recirculated liquid containing particulate matter. The invention also relates to a device for extracting particulate matter from waste material produced in peeling vegetable products.

Abstract: A system and method of optimising transmission of a program to multiple users over a distribution system, with particular application to video-on-demand for a CATV network (36). The system includes, at a head end of the CATV network (36) a scheduling and routing computer (30) for dividing the video program stored in long term fast storage (16) or short term fast storage (18) into a plurality of program segments, and a subscriber distribution node (24) for transmitting the program segments in a redundant sequence in accordance with a scheduling algorithm. At a receiver (40) of the CATV network (36) there is provided a buffer memory (42) for storing the transmitted video program segments for subsequent playback whereby, in use, the scheduling algorithm can ensure that a user's receiver (40) will receive all of the program segments in a manner that will enable continuous playback in real time of the program. Under the control of controller (52) the receiver (40) distinguishes received program segments by a segment identifier so that redundant segments captured in capture memory (46) are then stored in buffer memory (42) from which the segments can be retrieved and decompressed in data decompressor (50) for immediate or subsequent viewing.
