Title: Process for producing sugars and acids-rich juice and phytochemical-rich juice
Inventor: MANTIUS HAROLD L
IPC: A23L2/08
Filed: 2002-06-26
Abstract: A method is described for processing fruit or vegetables, e.g., cranberries, into two different juices (180 and 220). One of the two juices has a relatively high level of phytochemicals (170) and a relatively low level of sugars and acids. The other of the two juices has a relatively low level of phytochemicals and a relatively high level of sugars and acids (160). The method of the invention entails providing three juice streams. The first juice stream is passed through an ultrafiltration apparatus or some other apparatus that is capable of preferentially separating the relatively lower molecular weight compounds, e.g., sugars and acids, from the relatively higher molecular weight compounds, e.g., phytochemicals. This process creates two juice fractions: a juice fraction that is relatively enriched in sugars and acids and a juice fraction that is relatively enriched in phytochemicals.

Patent CA-2494738-A1 (CA)
Inventor: DUFFETT-SMITH PETER JAMES
IPC: G01S5/10
Filed: 2003-08-18
Abstract: The invention provides a method of estimating the time offsets between signa ls transmitted by plural transmitters of a communications network and received by a receiver attached to a terminal. In the method a section of a representati on of the signals from the plural transmitters received by the receiver at the terminal (a "terminal section") is created as are a first section of a representation of the signal transmitted by a first of said transmitters and a second section of a representation of the signal transmitted by a second of said transmitters. Each of the first and second sections overlaps in time wi th the terminal section. Using the first section, the second section and a set of signal parameters, including initial estimates of the time offsets between t he first section and the terminal section and between the second section and th e terminal section, a model of a section of a representation of the composite signal received by the receiver from the first and second transmitters is created. Thereafter, the model is compared with the terminal section and the set of signal parameters including the time offset estimates is refined to minimise the difference between the model and the terminal section. The time offsets in the refined parameter set used to minimise the difference between said model and the terminal section, are adopted as the estimated time offse ts between the first section and the terminal section and between the second section and the terminal section.

Inventor: GEBHARD RONALD
IPC: C07C251/24
Filed: 2003-11-03
Abstract: L'invention concerne un procédé permettant la préparation d'une base de Schiff énantiomériquement enrichie. Ce procédé consiste à faire entrer en contact une amine avec un composé carbonyle, l'amine et/ou le composé carbonyle étant un composé chiral, afin de former un mélange des énantiomères de la base de Schiff correspondante. Si l'amine constitue le composé chiral, le composé carbonyle est un aldéhyde aromatique, et si le composé carbonyle constitue le composé chiral, l'amine est une amine aromatique. Si l'amine et le composé carbonyle sont tous deux des composé chiraux, ils peuvent conjointement répondre aux deux significations décrites à la fois pour la situation amine chirale et la situation composé carbonyle chiral. L'étape suivante consiste à soumettre le mélange d'énantiomères de la base de Schiff à une chromatographie préparatrice sur une phase stationnaire, de manière à produire une séparation des énantiomères de la base de Schiff. A cette fin on utilisera de préférence une chromatographie chirale sur lit mobile simulé.
