Abstract: An apparatus (10) for analyzing lubricant oils and functional fluids includes an optical emission spectrometer (OES) (26) having a substantially continuously valued wavelength versus intensity output (140). The OES (26) analyzes light captured from a spark emission stand (58) through which the fluid sample is flowed. An expert system (160-172) operates according to a set of Rules, and generates diagnostic text (174) for an operator based on the information about the fluid sample provided by the OES (26) and other measurement devices. The apparatus (10) is reduce in size, weight and cost.

Abstract: A laminate optical article including a first outer layer; a second outer layer; and an inner layer positioned between said first and second outer layers, the inner layer providing a desirable optical property to the laminate optical article.

Abstract: The gauge and cess panels (3, 4) of a level crossing creep apart lengthwise of the track (1, 2) and need closing up again from time to time. A device (5, 24) for this consists of a member (8, 26) that engages under or over a rail (1) and has a portion (10, 27) extending transversely to the rail carrying a cam (6) or screw (28) for engaging the end of a panel (3, 4). When the cam or screw is turned, the reaction from the panel (3, 4) jams the member (8, 26) on the rail (1), and further turning forces the panel lengthwise of the track. Another device for gauge panels is a two armed toggle (29) with a cam (31) at its pivot (30), the arms (29) being in a shallow V with their free ends (32) braced against the insides of the rails (1).

Abstract: A painted plastics article in the form of a vehicle wing comprises a polypropylene substrate with a polyamide or polyester coating formed by dual injection or blow moulding. The coating makes the wing suitable for subsequent painting which may be carried out on a normal vehicle paint line used to paint a metal body-in-white. To promote adhesion between the polypropylene substrate and the coating, the substrate includes an admixture of a compatibiliser such as a maleic anhydride grafted polypropylene.

Abstract: A process vessel has side walls of concrete which are lined with a gas and moisture-impermeable material to prevent:a) the egress of gas from the interior of the vessel; andb) ingress of moisture through the concrete into the interior of the vessel.

Abstract: An absorbent article comprising, a liquid pervious top sheet, a backing sheet of fluid pervious material, an absorbent pad intermediate the top and backing sheets, and a coating of breathable adhesive substantially covering a front surface of the backing sheet facing the pad to define a liquid repellent barrier for liquids received in the pad. The backing sheet also has a pair of opposed end sections extending past end edges of the top sheet and having a coating of adhesive on the front surface, and a pair of release sheets covering the adhesive on the end sections. The article is useful as a surgical dressing, as a disposable diaper, sanitary napkin or the like products, particularly for absorbing aqueous body fluids.
