Abstract: Apparatus for continuously shaping a compressible or cellular polymer material, such as polyurethane foam, by cutting portions of the material from a surface of one or more slabs of material (180) includes two compression rollers (146, 146a), two moving patterned platforms (132, 132a) interposed between the compression rollers, and one or more cutting blades (76) for transversely cutting the slab or slabs just as the cellular material emerges from between the compression rollers. At least one of the moving patterned platforms, preferably an endless belt, defines a recess or pattern of recesses.

Abstract: The present invention relates to silver-containing and optionally promoter-containing supported catalysts and catalyst intermediates, processes for their preparation and their use for preparing alkylene oxides by oxidation of alkenes with oxygen. The catalysts are prepared by treatment of a support with a lactic acid containing silver ions, nitrate ions and optionally promoter metal ions, drying, predecomposition in a virtually oxygen-free atmosphere and subsequent activation by heating in an oxygen-containing atmosphere while precisely controlling the temperature conditions and the feeding-in of oxygen.

Suitable promoters are alkaline earth metal compounds and/or alkali metal compounds. High activities and high selectivities are achieved when using the catalysts of the invention for preparing alkylene oxides.
