Abstract: A construction composition comprises a) a cementitious binder comprising one or more calcium silicate mineral phases and one or more calcium aluminate mineral phases; b) optionally, an extraneous aluminate source; c) a sulfate source; d) an ettringite formation controller comprising (i) glyoxylic acid, a glyoxylic acid salt and/or a glyoxylic acid derivative; and (ii) at least one of a borate source and a carbonate source, wherein the carbonate source is selected from inorganic carbonates having an aqueous solubility of 0.1 g·L?1 or more, organic carbonates, and mixtures thereof; and e) a polyol in an amount of 0.2 to 2.5 wt.-%, relative to the amount of cementitious binder a). The composition contains 0.05 to 0.2 mol of total available aluminate, calculated as Al(OH)4?, from the calcium aluminate mineral phases plus the optional extraneous aluminate source, per 100 g of cementitious binder a); and the molar ratio of total available aluminate to sulfate is 0.4 to 2.0.

Abstract: A proposal is made for a cementitious system which comprises accelerator particles coated with crosslinked shellac, for the use as an additive component which comprises the accelerator particles coated with crosslinked shellac, and for a cement slurry which comprises the cementitious system and water.

Abstract: Suggested is a novel coated particle of active ingredients with controlled release properties at pH-values from 10 to 14, wherein the active ingredient is selected from one or more construction chemical additives for the control of inorganic binders, characterized in that the coating comprises shellac, a process for its manufacture and the use thereof as an additive for mortars, dry mortars, cement slurries and/or concretes.

Abstract: The invention relates to a pulverulent building material composition, preferably a factory dry mortar and in particular a tile adhesive, joint grout, knifing filler, sealing slurry, repair mortar, equalization mortar, basecoat adhesive, adhesive for composite thermal insulation systems (CTISs), mineral plaster or render, fine knifing filler or screed system, containing an ester of A) at least one compound selected from the group consisting of neopentyl glycol, 2-methyl-2-(hydroxymethyl)-1,3-propanediol and pentaerythritol with B) a carboxylic acid component.

Abstract: The invention relates to a powdery building material composition, preferably a factory-made dry mortar, and in particular tile adhesives, joint fillers, knifing fillers, sealing slurries, repair mortars, leveling mortars, reinforcing adhesives, adhesives for thermal insulation composite systems (TICSs) mineral plaster or render, fine knifing composition, and screed systems, containing an ester of A) 2-ethylhexanoic acid and B) an alcohol having a boiling point of at least 160° C. The invention further relates to the production of said products and to the use of the esters according to the invention in powdery building material compositions to reduce dusting.

Abstract: A sealing arrangement for sealing rolling bearings. The sealing arrangement has a carrier ring for carrying an elastic part which has a radial sealing lip, and therefore a second ring which is movable relative to the carrier ring. The second ring has a cylindrical part provided as a radial seat for the radial sealing lip. A first installation aid is integrally formed on the radial sealing lip and prevents the radial sealing lip from becoming fixed on a second ring, such as, for example, a spinning ring, by ensuring that the radial sealing lip expands at the right time.

Abstract: A chassis for a commercial vehicle, in particular a lorry, having a front module which has, on each side of the vehicle, a longitudinal member part and having an axle module which is fastened to the outside of the longitudinal member parts on each side of the vehicle in each case in a first coupling zone of the longitudinal member parts. The axle module has, on each side of the vehicle, an individual wheel suspension. Each of two lower A-frame arms are mounted with its second limb in a second coupling zone of the respective longitudinal member part. Both the first coupling zones and the second coupling zones are designed for at least two coupling configurations. The coupling can figuration differ from one another with regard to the vertical ground clearance of the longitudinal member parts.

Abstract: A wheel bearing unit having a bearing including an outer race attachable to a wheel carrier and a rotating inner race attachable to a wheel hub. The outer race includes a first plurality of mounting openings for mounting a brake caliper assembly, and second plurality of mounting openings for mounting the outer race on the wheel carrier. The first and second pluralities of mounting openings are symmetrically arranged enabling the wheel bearing unit to be used on the left and right sides of the vehicle with the caliper assemblies in the same relative positions on both sides. The first mounting openings lie at a substantially larger radial distance from the axis of rotation of the bearing than the second mounting openings, whereby the second openings overlie a region of higher strength in the wheel carrier, and the first openings are clear of the region of higher strength.

Abstract: In a support structure for a commercial motor vehicle including two longitudinal frame members between which a drive unit including an internal combustion engine and a transmission is arranged and wherein the support structure has an independent wheel suspension for each of the vehicles front wheels, each with an upper A-arm and a lower A-arm mounted to the support structure for supporting the front wheels, a support unit is provided which, in front and behind a space for receiving the drive unit extends around the longitudinal frame members and is fastened to the longitudinal frame members and on which at least the lower A-arms are mounted.
