The annular groove, on the coupling sleeve of pipes or fittings of polymers, is in this case provided with injecting and venting openings and, before injecting the sealing material, a split core mould, determining the inner contour of the sealing ring, is inserted into the coupling sleeve. It is regarded as the characterising feature of the invention that, before insertion into the coupling sleeve...

A method of controlling the recovery of landfill gas from a sanitary landfill and apparatus for performing the method. Landfill gas, which mainly consists of methane and carbon dioxide, is formed by anaerobic decomposition of the organic content of the refuse. This process develops a very small amount of heat. If more gas is drawn from the sanitary landfill than is formed by the anaerobic decompos...

Benzofuro[3,2-c]quinoline compounds of the general formula: wherein R<1> represents a hydrogen atom, a hydroxy group or an unsubstituted or substituted straight- or branched-chain alkoxy group having 1 to 10 carbon atoms wherein the substituent is selected from a hydroxy group, a carboxy group, a carbamoyl group and an alkoxycarbonyl group having 2 to 7 carbon atoms; R<2> represents a hydro...

The spring force is produced by at least two spring components (15,16), the first of which produces a spring force less than that produced by the second. A stop device (11-14) connects to at least one of the spring components so. Only the first spring is activated during an initial part of the cut-off movement. During the terminal part of the movement, only the second spring is activated.

Producing steam-cured aerated concrete where the slurry contains or has added to it a dispersing agent formed from one or more 10-20C C10-C20 alkyl carboxylic acid and one or more ethanolamines. The carboxylic acid may be mono unsatd. e.g. oleic. They may also be refined or unrefined tall oil acids or naphtenic acid from petroleum refining. The amine, which is pref. triethanolamine, is pref in 1.5...

Producing reinforced steam-cured aerated concrete involves the use of of a blend of two silicate components of differing degrees of crystallinity, where the material of lower crystallinity amounts to 50 - 80% of the silicate, and is particularly fly ash and where the slurry contains or has added to it a dispersing agent formed from one or more 10-20C alkyl carboxylic acid ethanolamine(s). The carb...

As a mould, a flexible, hose-shaped casing (3) is used, and the cable (1) is centred inside it by circular tensioners (5). The concrete or other hardenable material is then inserted into the casing, and allowed to harden when the casing with the cable inside is laid out in its required position. The concrete is pressed into the casing from one or both ends, and the normal procedure is for dry conc...
