摘要： A method and apparatus for determining the concentration of a target chemical species in a sample. A first spectrum is generated representing the absorbance of the sample across a range of wavelengths. The sample is then exposed to conditions which modify the concentration of the target chemical species in the sample, for example by irradiating the sample with UV or visible light which degrades the target chemical species, or generating an active species flux through the sample by exposing the sample to a corona discharge. The absorbance of the sample is then remeasured across the same range of wavelengths and differences between the two spectra are analysed to quantify the concentration of the target chemical species in the unmodified sample.

摘要： A split collar (1) for sealing a branch connection (8) which is connected to a pipe (2). The branch connection may be in the form of a ferrule from which a lead pipe extends. The lead pipe is flattened so as to be at least partially blocked, and the flattened portion (17) of the branch connection is then severed to define a stub projecting from the ferrule. A split collar is then clamped onto the pipe so that the stub and ferrule are enclosed within a cavity (3) defined by the collar and sealed by engagement between the collar and the pipe. The split collar forms a permanent fixture which reliably prevents any leakage from the branch connection stub, the ferrule, or cracks or holes in the pipe adjacent the branch connection which might appear at a later date.
摘要翻译：用于密封连接到管道（2）上的分支连接件（8）的开口套环（1）。分支连接可以是导管延伸的套圈的形式。导管被平坦化以至少部分地阻塞，然后分支连接件的平坦部分（17）被切断以限定从套圈突出的短截线。然后将开口套环夹紧到管上，使得短管和套圈封闭在由套环限定的空腔（3）内，并通过套环和管道之间的接合进行密封。开口环形成永久性固定装置，其可靠地防止在分支连接短柱，套圈或与稍后可能出现的分支连接件相邻的管道中的裂缝或孔中的任何泄漏。

摘要： An apparatus for producing a high solids content aqueous dispersion from a low solids content aqueous dispersion, for example waste water containing dilute emulsion paint. At least two membranes are arranged in series, a first membrane being of hollow fibre structure with a bore diameter greater than 1 mm and a pore size of less than 3,000 Kilodaltons molecular weight cut off, and a second tubular membrane being of bore diameter less than 50 mm and pore size of less than 3,000 Kilodaltons molecular weight cut off. The low solids content dispersion is passed across a face of the first membrane at a cross flow velocity of from 0.5 to 5.0 metres per second, a differential pressure being applied to force liquid through the membrane. The resultant retentate has an intermediate solids content and is passed across a face of the tubular membrane at a cross flow velocity of from 0.5 to 5.0 metres per second. A differential pressure is applied across the tubular membrane to force liquid therethrough. The resultant retentate is of high solids content, for example greater than 40 % solids content given a starting dispersion of from up to 5 % solids content.

摘要： An optical measurement instrument for monitoring characteristics of a liquid such as water. An optical beam is generated and directed into the thread (7) of liquid such that the beam is guided along the length of the thread by total internal reflection. Components of the beam that are affected by variations in characteristics of the liquid defined by the thread are detected. These components may be derived from the thread by causing the thread to impinge against a window (8) behind which the detector (9) is located or by detecting back-scattered components of the beam. Relatively long interaction lengths between the beam and the liquid can be achieved.

摘要： A porous membrane is produced by gelation in a non-solvent medium of an aromatic ether ketone polymer dissolved in a strong acid which is substantially non-sulphonating to the polymer. The polyether ketone solution includes a polymer additive which is not substantially degraded by the strong acid and which is soluble both in the strong acid, the non-solvent and mixtures thereof. The gelation medium may, for example, be aqueous and the polymer additive may be polyvinylpyrrolidone. Membranes produced by the method of the invention have good overall performance and flux at any given molecular weight cut-off.
