摘要： A cover (1) for temporarily covering a trench, e.g. in a thoroughfare such as a road or footpath, by extending over, and resting on the ground on opposite sides respectively of the trench, the cover (1) being releasably engageable with other adjacent covers (1a and 1b) by means of male members (5 and 5b) mating with respective corresponding female members (6a and 6) in such a manner that when the covers (1, 1a and 1b) are engaged in a ground resting position to form an assembly (7) of covers, one cover (1b) of the assembly can be disengaged from the adjacent cover (1) only by moving the cover (1b) out of the general plane of the assembly.

摘要： Joints and leaks in pipelines or mains are sealed by injecting into the joint or leak a sealant by means of an expandible tubular pig which is moved endwise through the pipeline or main. The sealant is in the form of an anaerobically curable monomer which cures in the relatively air free conditions in the joint or leak. The pig forms within the pipeline or main an air-free space which communicates with the joint or leak and which is isolated from the fluid in the main. Nevertheless the pig is hollow to permit the flow of fluid therethrough while the joint or leak is sealed. The sealant is injected into the joint or leak by way of the space so that the sealant cures in situ in the joint or leak.
摘要翻译：管道或管路中的接头和泄漏通过注入接头或通过可伸缩的管状猪泄漏密封剂进行密封，该管状猪通过管道或主管端部移动。密封剂是以可厌氧固化的单体的形式，其在接头或泄漏的相对空气条件下固化。猪在管道内形成，或者主要形成与接头或泄漏连通的空气空间，并与主体的流体隔离。然而，当密封接头或泄漏时，猪是中空的，以允许流体流过其中。密封剂通过空间注入接头或泄漏，使密封剂在接头处原位固化或渗漏。

摘要： Soluble thiosulphates present in aqueous redox systems comprising at least one salt of an anthraquinone di-sulphonic acid and at least one water soluble compound of metal having at least two stable oxidation states, for example a vanadate, are converted to sulphates by introducing oleum or sulphuric acid into the lower half of a vessel containing said thiosulphate containing redox solution, wherein the sulphuric acid has a concentration of from 10-98% w/w H.sub.2 SO.sub.4 and the amount of said sulphuric acid is such that the gram molecular weight ratio of sulphuric acid to thiosulphate is from 1:2 to 1:3, and thereafter separating the sulphate formed for example by using a solubility lowering technique. The process is carried out at ambient temperature and at a temperature of from 70.degree. C. up to the boiling temperature of the acidic mixture.

摘要： A method and kit is provided for temporarily blocking the bore of a pipe through which a fluid flows, the kit including an expansible flexible bag seal which is inserted through a hole provided in the wall of the pipe injecting into the bag seal. A quantity of a material adapted to expand in situ in the bag seal and inflate the bag seal to seal against the inside of the pipe is injected into the bag seal. The pipe may be a gas main and the material may be an expandable synthetic resin foam. The bag seal is removed by injecting thereinto a substance capable of dissolving the foam so that the bag seal can be at least partially deflated.
