Abstract: A method for identifying and/or differentiating between asbestos materials and aramid materials comprises the steps of rubbing an area of a surface of a material (44) to be identified, with an acrylic reference material (28), measuring the polarity of the generated electrostatic charge and comparing the polarity with polarities of charge generated from surfaces of known asbestos and aramid materials.

Abstract: To enable a spectrometer (10) to be used for taking analysis readings from plastics articles (24) of varying shapes and degree of preparation, the spectrometer (10) is enclosed within a housing which has an interface device (14) attached to the sensing window (58). The interface device (14) is sensitive to the positioning of a sample (24) in position to carry out sample preparation tasks as the sample is brought into the analysis position opposite the sensing window (58). The interface device (14) comprises a front wall (16) with a sample aperture (18) against which the sample (24) can be placed so that a surface of the sample (24) is exposed through the aperture (18), means (48) for cleaning a sample surface (24) placed against the front wall (16), means (52) for extracting debris resulting from the sample cleaning, and means (30, 32) for guiding the front wall (16) towards the sensing window (58) to enable the spectrometer (10) to take a reading from the sample surface (24).

Abstract: A headrest is made from a blow-molded plastic body which has a re-entrant formation over part of its surface, the fixings for securing the body to the headrest support being located inside the re-entrant formation, and the walls of the formation cooperating with the support to define the limits between which the headrest can tilt about a horizontal axis.

Abstract: A tray or drawer for mounting beneath a seat in a motor vehicle is mounted on rails so that it can slide out forwards and then tilt to allow access to the interior space of the tray.
