摘要： A process is described for rock consolidation, e.g. in tunnel construction and mining, by injection of aqueous preparations of melamine resin condensates and/or urea formaldehyde condensates together with an acid curing agent. The process is characterized by the use of aqueous solutions of hydrogen sulfate salts, especially solutions of alkali and/or ammonium bisulfates, as curing agents. The curing agent solutions can contain additional auxiliary agents and active substances such as corrosion inhibitors, structurizers and adhesion agents. Preferred resin solutions for consolidation with these aqueous curing agents contain added zeolite NaA and/or hydrosodalite for increasing their serviceability, and especially for prolonging their storage life.

摘要： The present invention relates to a piston (10, 110, 210) for an internal combustion engine, having a piston base body (11, 111, 211) and a piston ring element (12, 112, 212), whereby the piston base body (11, 111, 211) has at least an inner region (14) of a piston crown (13) as well as a piston skirt (16), which is provided with pin bosses (18) having pin bores (17), whereby the piston ring element (12, 112, 212) has at least an outer region (21) of a piston crown (13) having a circumferential top land (22), and a circumferential ring belt (23) provided with ring grooves (24). According to the invention, it is provided that piston base body (11, 111, 211) and piston ring element (12, 112, 212) are joined together by way of corresponding, conical joining surfaces (32, 33, 27, 28; 135, 136; 232, 233, 227, 228) configured on them. The present invention furthermore relates to a method for the production of such a piston.

摘要： A multi-part piston for an internal combustion engine has an upper piston part and a lower piston part. The upper piston part and the lower piston part each have an inner and an outer support element, which elements delimit an outer circumferential cooling channel and an inner cooling chamber, whose cooling chamber bottom has an opening. The opening is closed off with a separate closure element, which has at least one cooling oil opening.
