摘要:
A process for extracting a wide range of lipophilic compounds from urea-containing solutions is described. The process utilises a near-critical fluid as the extraction solvent. The process is particularly applicable to the extraction of polyunsaturated fatty acids from the filtrate obtained upon urea fractionation, as employed in the processing of fish and other oils. In contrast to known processes, the lipophilic compounds may be extracted without the use of non-food grade solvents, and are suitable for pharmaceutical and cosmetic use.

Conventional obstacles to entry and survival of small graphic-arts service providers are softened—particularly for those businesses that operate as computerized “ASP” enterprises involving wide-area networks—by encouraging small operators to coexist effectively in use of a pivotal network-based service. One key mechanism promoting this capability is a system of optionally mutual links between the pivotal service and the ASPs. The service also counteracts a tendency in the industry to favor wastefully redundant vertical integration. On the other hand, the system also implements the prerogatives of an enterprise (such as a printing-broker ASP) that has an established customer, to closely channel the attention of that customer—but subject, importantly, to being overruled by the customer. Ideally the system is carefully tuned to enable such customer action without unduly pressing the option upon the customer.

Automatic testing determines whether a proofing-file generator and receiver are in a common intranet. If so then the proofing file is automatically sent by a route that is substantially wholly within the intranet, and ideally peer-to-peer. If the generator and receiver are not in a common intranet, then preferably the file is sent by a conventional route through the Internet, preferably via a master server of the proofing service. The test preferably includes dynamically establishing IP addresses for the generator and receiver, and comparing the established IP addresses; however, consultation of a pretabulated listing is also possible.
摘要:
A method of providing a copy of at least a portion of a document (2) comprising providing the document (2) with at least one document identifying indicia identifying at least a portion of the document, comprising the following steps, providing an indicia reader (8) to read the indicia on the document, reading the indicia with the indicia reader (8) and generating indicia data representative of the indicia, identifying the document (2), and/or portion thereof, from the indicia data generated by reading the indicia; and obtaining an electronic copy of the document and/or portions thereof identified by the indicia data.
摘要:
A passivated semiconductor structure and associated method are disclosed. The structure includes a silicon carbide substrate or layer; an oxidation layer on the silicon carbide substrate for lowering the interface density between the silicon carbide substrate and the thermal oxidation layer; a first sputtered non-stoichiometric silicon nitride layer on the thermal oxidation layer for reducing parasitic capacitance and minimizing device trapping; a second sputtered non-stoichiometric silicon nitride layer on the first layer for positioning subsequent passivation layers further from the substrate without encapsulating the structure; a sputtered stoichiometric silicon nitride layer on the second sputtered layer for encapsulating the structure and for enhancing the hydrogen barrier properties of the passivation layers; and a chemical vapor deposited environmental barrier layer of stoichiometric silicon nitride for step coverage and crack prevention on the encapsulant layer.
摘要:
A method of associating a first electronic document with a second electronic document comprising having a first physical paper identifier (130) having pen-readable coding (12) which codes for an identifier for the first electronic document, and reading the coding of the first electronic document with a pen (20) to acquire information enabling the identity of the first electronic document to be established, and communicating that identity to a computer processor (107), and using the processor (107) to associate the identified first electronic document with the second electronic document.
摘要:
A digital pen system comprising a pen 8 adapted to mark a medium 2 and a sensor 12 arranged to determine the position on the medium 2 of a mark made by the pen 8, the system being arranged to identify a plurality of different areas 500 on the medium 2 and being further arranged to authenticate a user in dependence upon authentication data input by the user, the authentication data having a value dependent upon the order in which a group of the plurality of different areas 500 of the medium 2 are marked by the pen 8.
摘要:
A foldable stamp sheet that includes a backing sheet, at least one label on the sheet, the label having an adhesive backing that allows it to adhere to the backing sheet in a non-permanent manner, each label having a scored section along a midline of the label, at least one stamp formed on each label, at least one pull tab on the sheet, the pull tabs being positioned in an area where the sheet is to be folded when the pull tab is removed from the sheet.

摘要:
A data structure which defines an electronic document comprises first and second substantially separate portions of data. The first portion of data defining the content of the document and the second portion comprising data relating to a pattern of position identification markings (106) such that when the electronic document is printed a pattern reading device, such as a pen (300), is able to determine its position relative to the position identification markings.
