Abstract: PCT No. PCT/SE97/00807 Sec. 371 Date Nov. 19, 1998 Sec. 102(e) Date Nov. 19, 1998 PCT Filed May 16, 1997 PCT Pub. No. WO97/44219 PCT Pub. Date Nov. 27, 1997A method and apparatus for extracting oil from water, particularly spillage water from gasoline stations and water that emanates from vehicle-washing plants. The method and apparatus utilize filters to which contaminated water from the vehicle-washing plant and other contaminated water is passed. The water is cleansed in one or more mutually sequential filters arranged in the flow direction of the water. The water is cleansed by first causing the water to flow through a collection filter in which oil and coarse particles are collected in a first cleansing stage. The water from the collection filter is passed through a fine filter adapted to lower the oil content of the water to a level below about 50 to 70 mg/l in a second cleansing stage. The water from the fine filter then flows through a membrane filter that is adapted to filter-off at least 75% of the oil remaining in the water during a third cleansing stage. At least a substantial part of at least the water cleansed in the membrane filter is recycled back to the vehicle-washing plant while any residual part of that water is discharged to a municipal sewage network.

Abstract: The present invention relates to a fuel system as well as a method for controlling the same. More specifically, it relates to a fuel system of motor vehicles adapted to be powered by alcohol-containing fuels, and specifically by alcohol-containing fuels and by petrol, so-called Flexible Fuel Vehicles (FFV). These vehicles can be powered by fuels with varying alcohol content, and also by pure petrol. The fuel system according to the invention comprises a main tank (1) for fuel, a cold-start tank (2) with fuel which is sufficiently inflammable to be used in connection with cold starts, as well as fuel line system connecting these tanks to each other and to injection means of the engine of the vehicle, where at least one pump (8, 13) is adapted to transfer fuel through the fuel line system. Specifically, the invention relates to a system which is controlled so that fuel is transferred from the main tank (1) to the cold-start tank (2) when the alcohol content of the fuel is below a predetermined threshold value.

Abstract: The invention relates to secure distribution of a private key from a distributing unit to a receiving unit, and is based on providing each of the distributing unit and the receiving unit with a protecting circuit holding an original private key unique for the protecting circuit. The protecting circuit of the receiving unit is associated with a certificate holding information on the type of the protecting circuit. The protecting circuit of the distributing unit requests this certificate to verify the authenticity by using a public key, of a certificate authority, stored in the protecting circuit. Next, the protecting circuit determines, based on the type information of the certificate, whether the protecting circuit of the receiving unit represents a type of circuit that is acceptable for protecting the private key to be distributed. If the protecting circuit is found to be acceptable, the private key is encrypted and transmitted thereto. The received key is decrypted and stored in the protecting circuit of the receiving unit. In this manner, the private key is protected during transfer and may be distributed to and securely protected in one or more receiving units.

Abstract: Improving the accuracy of measurements by sensors, to determine the signals of fluorescent emissions, comprises fitting a fluorescence standard strip to each sensor as a charge of reference material. Each fitted strip is measured with a high-precision process fluorimeter. The individual deviation of the fluorescent signal from the nominal charge value is determined for each sensor. Improving the measurement accuracy of fluorescent sensors, comprises determining an internal correction value (alpha) from each individual deviation from the nominal value, to be transferred to a data carrier which has the sensor or an appropriate database. An analysis calibration takes a random sample from the sensor charge at a sensor, to be measured by calibrators with known analyte concentrations, to establish the relationship of the fluorescent signal from the analyte concentration for each assay. The correction value is scanned for each sensor, or taken from the database, to establish the relationship between the analyte concentration of the assay and the fluorescent standard strip. The ratio (beta) for the separate analyte concentrations in the assay at each sensor gives a calibration curve to be taken in as information at the sensor or into the database. To measure a sample of unknown properties, the measured fluorescent signals from the assay and the fluorescent standard strip are related to each other and multiplied by the correction value to determine the ratio. The ratio value and the calibration curve for the sensor determine the analyte concentration in the sample.

Abstract: In a method for manufacturing and forming meat and sausage products, a semi-finished meat or sausage product is brought into a foil bag or between foils and sealed under vacuum to form a filled package. The filled package is then aligned between two movable, adjustable plates, and a uniform distribution of the package contents is achieved by applying a slight pressure on the package by moving the plates against one another. A vacuum is generated in plate cavities provided in the plates upon reaching a certain plate distance or a pressure within the filled package. In this way, the foil of the package undergoes stretching within the plate cavities and a cavity wall of the plate cavities, and the semi-finished meat or sausage product assumes a surface shape of the plates.
