    Abstract: A method and apparatus for securely joining a sleeve (10) to an end portion of a pipe (20). The method comprises positioning at least a portion of a sleeve (10) over an end portion of a pipe (20) to form an annular space (21) between the outer surface of the pipe (20) and the inner surface of the sleeve (10), inserting grout into the annular space (21) and allowing the grout to cure to secure the sleeve (10) to the end portion of the pipe (20).

    Abstract: A method and apparatus for determining the effective composition of a mixture of gases including a plurality of hydrocarbon gases, the method comprising selecting one or more effective hydrocarbons to represent the plurality of hydrocarbon gases in the gas mixture, the number of effective hydrocarbons being less than the number of hydrocarbon gases in the gas mixture whose composition is to be determined; measuring a number of characteristics of the gas mixture whose effective composition is to be determined, the number of characteristics to be measured being one less than the total number of components to be determined and determining the effective composition of the mixture of gases from the measurements of the characteristics of the gas mixture, a predetermined parameter dependent upon the characteristic measured and knowing that the sum of the components of the gas mixture equals 100 %.

    Abstract: A method is provided for securing a branch assembly (1) to a "live" pipeline (6). An upper part (2) of the assembly incorporating the branch (13) is positioned on the pipeline over a containment ring (16) located on the pipeline and within which there is an annular seal (17) surrounding an area (6a) from which the branch is to extend. A lower part (3) of the assembly is positioned on the pipeline beneath the upper part and the two parts are secured together so that the seal is compressed and an annular space (19) is left between the two parts and the external surface of the pipeline. Grout is injected into the annular space (19) and cures to bond the two parts forming the branch assembly in position on the pipeline. The use of grout avoids having to use welding techniques on a "live" pipeline. A coupon can be cut out of the pipeline, via the access through the branch.

    Abstract: The method detects the presence of poly-chlorinated biphenyls on a surface, by the use of UV fluorescence spectroscopy in the back-emitting mode. The apparatus comprises a source of UV radiation. Exposure means are provided for conveying UV radiation from the source to the surface. Collecting means collect radiation back-emitted from the surface. A filter filters the collected radiation, and a spectrometer analyses the filtered collected radiation. The filter allows radiation having a wavelength within the range of from 320 nm to 360 nm to pass to the spectrometer.

    Abstract: The method detects the presence of an effective corrosion inhibitor in a central heating system liquid. A clean steel electrode and a non-steel electrode are immersed in the system liquid. The galvanic current flowing between the electrodes is measured after a delay, and the measured current is compared with a reference. A portable apparatus for carrying out the method comprises a sample container (10) and a measurement instrument (12) which includes a steel electrode (14), a non-steel electrode (16), circuitry (19) for detecting galvanic current flowing between the electrodes when immersed in a test liquid in the container, and generating a measurement signal indicative of the measured galvanic current. The method and apparatus provide a quick effective method of checking correct inhibitor function.
