Patent GB-2365284-A (GB)
Title: Data compression system which selects compressed output from one of two different compression schemes
Inventor: PELLY JASON CHARLES
IPC: H03M7/30
Filed: 2000-07-25
Abstract: The system has two compression encoders one of which is an ALDC (adaptive lossless data compression) encoder <B>950</B> where data words are buffered in a memory at the transmitter and receiver and series of data words which repeat series which have already been transmitted are replaced with a reference to the respective data word string stored in memory. The other encoder <B>970</B> may apply these adaptive string matching techniques to only parts of data words or to data words which have a similar numerical value. The output of each encoder is fed into a respective buffer <B>960/980</B>. Once the amount of data in either buffer exceeds a threshold capacity the ALDC encoder is allowed to complete encoding any series of matching data words it is currently operating on and then an output circuit <B>990</B> determines which buffers' contents will be output from the system. This is generally selected on the basis of the best compression ratio. The selected contents of the compressed buffer are then output along with an indication of the compression scheme used. Decompression systems (see figure 17) receive the compressed data stream and decompress it using the compression scheme indicated in the control information transmitted with the compressed data block.

Title: Pectin based fruit filling
Inventor: FLEMING ANDREW EDWARD
IPC: A23L29/231
Filed: 2000-09-15
Abstract: A pectin-based non-gelled aqueous composition comprises at least 70% of one or more sugars, pectin having a degree of esterification (DE) of 15% or below and water having a calcium ion concentration of no more than 35mg/l. The aqueous composition can be used to form a gelled heat stable fruit filling which comprises 0.3% or more of the low DE pectin, one or more sugars, water and a fruit concentrate, wherein the filling has a water activity (a<SB>w</SB>) of 0.6 or less. The gelled fruit filling is made by heating the above aqueous composition to increase the RSS (refractomeric sugar solids) value of the composition to 75% or more, optionally adding a humectant, cooling the composition, adding a fruit concentrate and mixing the resulting composition to control the consistency of the gel. The fruit concentrate is added after the composition is heated to avoid degradation of the concentrate and help ensure a low water activity allowing a longer shelf life for the product. The fruit filling is extrudable over a large temperature range and can be incorporated into a wide range of baked or fried products for example fruit nuggets.
