Abstract: A process for preparing storage-stable, aqueous polyorganosiloxane emulsions includes preparing an emulsifier-water mixture that includes at least one alkyl polyglycoside (B) and water (C) and optionally further emulsifiers (D), optionally thickeners (E) and optionally further additives (F). The process also includes preparing a preliminary emulsion by addition of at least one polyorganosiloxane (A) to the emulsifier-water mixture. The preliminary emulsion is prepared under the action of low shear forces using stirring devices with a maximum peripheral speeds of 4.5 m/s. The process yields polyorganosiloxane emulsions having a particle size D(50) of 1 ?m to 50 ?m, based on the D(50) value of the volume distribution measured in accordance with the principle of Fraunhofer diffraction (according to ISO 13320).

Abstract: Method of and apparatus for continuous non-destructive testing of bar-shaped specimens formed of iron-containing material of specific quality characteristics, where the bar-shaped specimens, such as pipes, move on a roll table (2) along an elongated path through two testing blocks (8, 9) spaced apart along the path. The testing blocks (8, 9) are mechanically decoupled from one another and are logically linked to an electronic testing installation (10). As a specimen moves through a first testing block (8) a signal is developed indicating the presence or absence of flaws and their location in the specimen. The location is referred to the length of the specimens. The testing blocks (8, 9) are located between a supply station (1) and a sorting station (3) with the roll table (2) extending between the two stations. Based on the signals generated, the specimens are sorted in the sorting station between an accepted tray (4) and a number of rejected trays (5, 6, 7) for reworkable or scrap specimens.
