Title: Method of preparing a muscadine pomace extract
Inventor: IANIRO TEODORO T
IPC: A23L33/00
Filed: 2014-03-12
Abstract: Muscadine grape extracts are disclosed that have antioxidant properties. The extracts are a mixture of extracts from bronze and purple muscadine grapes that unexpectedly increase the solubility of ellagic acid in the mixture. Solvent extracts are obtained in some examples by water extracting the pomaces of the grapes from which the juice has substantially been removed. Further surprising increases in ellagic acid solubility can also be obtained by adding an additional source of anthocyanins to the extract, for example by including in the composition an extract of whole purple muscadine grapes from which substantial amounts of the juice have not been removed. Other additional sources of anthocyanins include blueberries, blackberries and raspberries; the additional source of anthocyanins can be obtained from a fruit processing waste stream to increase the efficiency of the production process.

IPC: B03D1/02
Filed: 2016-08-17
Abstract: An oleophilic separation apparatus and process for replacing bitumen froth flotation with a more efficient high quality bitumen production process that is ten times faster, operates at 30 degrees centigrade or lower and does not require caustic process aid. It features tumbling oleophilic balls or oleophilic rods in a driven rotating agglomerator cage with apertured cylindrical wall that hangs in closely spaced multipe wraps of endless oleophilic metal or plastic rope from internally heated rollers to produce high purity warm free flowing bitumen product from oil sand slurry or from tailings pond fluid fine tailings feed. The rods or balls transfer from the feed to their surfaces bitumen paste with a viscosity similar to conventional ketchup or tooth paste. This paste extrudes through the bottom of the apertured cage bottom to the oleophilic rope wraps for conveyance to internally heated rollers above the drum to produce a free flowing high quality bitumen product. The aqueous effluent tailings flow out of the drum past the wraps and may be stored for a few months in a working tailings pond to settle solids and to concentrate bitumen in the resulting fluid fine tailings for subsequent recovery at ambient temperature of more bitumen to achieve very high total bitumen recovery. The process features short processing time, low thermal energy requirements and minimal materials handling. It may lead to bitumen extraction right at the mine face to reduce: 1) the cost of producing bitumen, 2) the environmental impact of bitumen production and 3) the cost of purchasing carbon credits resulting from its low energy requirements.

Inventor: CRAVEN PETER GRAHAM
IPC: G10L19/008
Filed: 2015-03-26
Abstract: An encoding method and encoder is provided for transparent lossless audio watermarking by quantising an original PCM audio signal twice, each quantisation quantising to a quantisation grid. As a PCM signal is inherently already quantised, there are three quantisation grids to consider, the first being the quantisation grid of the original PCM signal, the second being that of the watermarked signal and the third being that of an intermediate signal. The technique reduces the amount of introduced quantisation error, spectrally shapes the error and fully decorrelates signal alterations from the original audio, thus making the error more similar to additive noise. A decoding method and decoder is also provided, as is a method of altering the watermark without fully decoding the encoded signal.
