摘要： The present invention relates to a method of preparing crystalline, zeolitic aluminosilicates with SiO.sub.2 /Al.sub.2 O.sub.3 ratios of 20 or more. The method provides a rapid, two-stage crystallization process which avoids the formation of secondary crystalline phases. The first stage is conducted at a temperature between 240.degree. C. and 325.degree. C. for between about 1 and 20 minutes. The second stage is conducted at a temperature between about 120.degree. C. and 225.degree. C. for about 1 to 100 hours.

摘要： A sheet-separating device for separating individual sheets from a stack, for example in the printing machine includes pneumatically operated suction heads engageable with the uppermost sheet of the stack, a four-link transmission device effecting a vertical movement of the suction heads relative to the stack and having a swinging arm connected to the suction heads, and an oscillating device including a pivotable connecting rod connected to the suction heads, and a vertical slide connected to the connecting rod so that a limited oscillating horizontal movement is imparted to the suction heads in addition to the vertical movement.

摘要： A flame retardant polymer composition consists of a) 20–60 percent by weight of a thermoplastic and/or cross-linked or cross-linkable elastomer and b) as a flame retardant agent 40–80 percent by weight either of an aluminum hydroxide with the material values specific surface according to BET 3–5 mg2/g mean grain size d50 1.0–1.5 μm residual moisture 0.1–0.4% oil absorption 19–23% water absorption 0.4–0.6 ml/g or of an aluminum hydroxide with the material values specific surface according to BET 5–8 m2/g mean grain size d50 0.8–1.3 μm residual moisture 0.1–0.6% oil absorption 21–25% water absorption 0.6–0.8 ml/g. A process of producing the flame retardant agent is characterised in that a filter-moist aluminum hydroxide obtained by precipitation and filtration with a mean grain size of 0.8 to 1.5 μm is subjected to mill drying in a turbulent hot air stream in such a way that, while the grain distribution is largely retained, the BET surface is increased by at least 20%.
