    摘要： Method of preventing deposits of dissolved inorganic salts on heated surfaces, such as tubular heat exchangers, is carried out by adding a deposit-preventing agent to the water before contact with the heated surfaces. Compounds complexing with cations are combined with anionic substances which are capable of salt formation with complex bound cations to form additive compositions which are added to the water in the zone near the walls of vessels or tubular heat exchangers subject to deposit incrustation. Such compositions are formed from cation-complexing compounds comprising a mixture of sulfurous acid esters of di- and/or polysaccharides and carboxymethyl cellulose as cation-complexing compounds, which mixture is combined with anionic substances comprising sulfonated fat by alcohols and/or fatty acids in the weight ratio having a range of from about 80 parts by weight cation-complexing compound to about 20 parts by weight anionic substance to (2) about 95 parts by weight cation-complexing compound to about 5 parts by weight anionic substance, the preferred weight ratio being 85:15 to 90:10 of cation-complexing compound; anionic substance, respectively. These compositions are added to the water in amounts ranging from 10 to 60 milligrams per liter, preferably 20 to 30 milligrams per liter.

    摘要： A mechanical joint for an insulated line is disclosed which includes a joint fitting having a cylindrical passageway therethrough for receiving at least two pipes which are to be mechanically joined but electrically insulated from one another. At one end, the fitting is connected directly by a suitable mechanical means to one of the pipes which extends into the passageway. At the other end of the fitting, an annular groove is formed about the inside periphery of the fitting so that a deformable ring gasket, formed of an electrical insulating material, can be positioned in the groove between a second pipe and the fitting. A gasket follower ring is positioned next to the ring gasket in the annular groove and a means is provided for pressing the gasket follower against the ring gasket so as to deform the gasket to grip the pipe positioned within the passageway. At least one insert receiving cast groove is also formed in the fitting proximate the end of the fitting and has a relatively large opening into the passageway therethrough and has a relatively small opening to the outside periphery of the fitting. A lock insert formed of an electrical insulating material is positioned in each groove and a cup-pointed set screw is threaded therethrough from the outside of the fitting until the set screw engages the pipe to a predetermined depth, thereby locking the pipe in position with respect to the fitting.
