  • Publication number: 20180038727
    Abstract: A method and apparatus for determining the location of a substantially horizontal fluid interface within a vessel are provided. The apparatus has a generally linear source array comprising a plurality of sources of penetrating radiation and a generally linear detector array comprising a plurality of radiation detectors capable of detecting radiation emitted by the sources. The source and detector arrays are located so that radiation emitted from each source can follow a linear path from the source, through the vessel and material to the detectors. Comparing the amount of radiation received by at least two of the detectors from a source provides an indication of the relative density of the material through which radiation has passed. The linear axes of the source and detector array are oriented with respect to the horizontal interface such that the linear axes intersect the plane of the interface at an angle between 10 and 80 degrees.

  • Patent number: 9765673
    Abstract: A system and method of monitoring regeneration of a particulate matter filter for a stationary diesel engine is disclosed. The system monitors exhaust temperature and operating time of an engine to calculate accumulated operating time below a critical temperature. Upon reaching a maximum allowed accumulated operation time, the system initiates a warning signal to inform the operator to increase exhaust temperatures for passive regeneration of the filter. During regeneration, the system periodically measures filter pressure differential and the exhaust temperature to calculate a difference in pressure differentials measured at two different times and determine whether the difference is below a critical value to inform the operator that regeneration is complete.

  • Patent number: 9720173
    Abstract: A method of manufacturing a security feature for identifying objects or documents of value. The method may include the steps of encoding information in a pattern; and ink jet printing a chiral nematic liquid crystal material from a reservoir using a print head on to a substrate in the pattern. Thus, the method forms a patterned array of chiral nematic liquid crystal material deposits. The print head, or the reservoir, or both, may be heated to a temperature above the clearing point of the chiral nematic liquid crystal material. The chiral axes of the chiral nematic liquid crystal material deposits may be aligned substantially perpendicular to the substrate such that a predetermined portion of the electromagnetic spectrum is selectively reflected over other regions of the electromagnetic spectrum by the chiral nematic liquid crystal material deposits.

  • Patent number: 9658202
    Abstract: A method of identifying a product comprises forming a tagged product by adding to said product a tracer material comprising at least one tracer compound which is acceptable for use as an additive in food and subsequently analyzing a sample of said product to determine the presence of said tracer compound thereby to determine whether said sample is a sample of the tagged product. The method is especially useful for the identification of vegetable oil products from sustainably managed sources. The use of permitted food additives as tracers enables the product to be identified in the supply chain while also allowing it to be used safely in foodstuffs if required.
