The invention relates to a compact reactor that consists of a number of plates that are arranged like stacks and spaced some distance apart, whereby a) The plates are separated by spacers and are sealed off from one another in a gas-tight manner, b) The plates are profiled in the shape of waves, so that flow channels are formed by the wave troughs that are separated from one another by the wave crests (fins), c) The flow channels run parallel to one another and parallel to one side of the plate, d) The flow channels at least partially contain at least one catalyst material that is introduced such that gaseous and/or liquid media can flow through the flow channels, and e) The compact reactor has means (headers) for feeding at least two gaseous and/or liquid media to the flow channels or removing them therefrom. The invention also relates to the use of a compact reactor. The gaseous and/or liquid medium that flows in the flow channels can flow through the fins between the individual flow channels of a plate.

The invention relates to a spreader structure (10) for introducing into a hollow organ, comprising spreader rods (12), which radiate from a first connection section (14) essentially in the longitudinal direction (36) of the spreader structure (10) up to a second connection section (16), are distributed around the periphery of the spreader structure (10) and can be placed against a wall of a hollow organ by means of radial expansion. The aim of the invention is to provide a spreader structure (10), which is versatile and cost-effective to produce. To achieve this, the spreader rods (10) have at least one zone (22) running in the longitudinal direction, which has a reduced flexural strength in comparison to neighbouring zones (20, 24). The invention also relates to the use of said spreader structure, to a spreader device and to a method for positioning a spreader structure.

摘要:
A semiconductor memory configuration in a semiconductor substrate includes bit lines, word lines, and memory cells each including one memory capacitor and one MOS selection transistor having two conducting regions and a gate electrode. Each memory capacitor is connected to one of the conducting regions of the transistor. The other of the conducting regions of the transistor is connected to one of the bit lines, and the gate electrode of the transistor is connected to one of the word lines. An insulating field oxide or buried insulating oxide with substantially vertical sidewalls is provided. A trench lies adjacent to the insulating field oxide or buried insulating oxide and adjacent to one of the conducting regions. The capacitors are each disposed in one trench for each memory cell. A first insulating layer covers the inner trench wall surface. A first electrode of the capacitor is disposed perpendicular to the substrate surface on the first insulating layer completely inside the trench. A second insulating layer is disposed on the first electrode. A second electrode is disposed vertically on the second insulating layer in the trench. A contact is connected between the first electrode of the capacitor and one of the conducting regions of the transistor laterally through an opening formed in the first insulating layer on the inner trench wall surface. Methods for producing the semiconductor memory configuration and a memory matrix having at least four of the memory cells, are also provided.

A magnet system for a nuclear spin tomograph having at least one field producing magnet coil S.sub.1 with radius r.sub.s1 arranged in a middle plane which produces a homogeneous magnetic field in an investigational volume directed along a z-axis perpendicular to the middle plane, is characterized in that at least one, preferentially at least two, ferromagnetic rings R.sub.i with radius r.sub.Ri are provided in the middle plane concentric to the magnetic coil S.sub.1. A system of this kind can be substantially more compact in construction than conventional systems with equal produced field strength. In addition substantially reduced currents are required through the coil or coils for field production.

A method of manufacturing orthosubstituted alkylphenols, employing a catalyst of increased activity, by reacting phenol or 2-alkylphenols with 2-alkyl-1-alkenes and/or 2-aryl-1-alkenes in the liquid phase, optionally in the presence of inert diluents and/or an excess of the alkene, wherein the reaction is carried out in the presence of modified aluminum-containing catalysts obtained by adding small amounts of polyhalophenols, each having at least 3 like or unlike halogen substituents from the group of the elements fluorine, chlorine, and bromine, serving as cocatalysts, to known aluminum trisphenolate catalysts, wherein the molar ratio between the cocatalysts and the aluminum compound is in the range 0.5:1-8:1.The invention also relates to the catalyst for manufacturing the ortho-alkylated phenols, which catalyst is comprised of the (2-alkyl)phenol undergoing alkylation, an organoaluminum compound, and a polyhalophenol as the (or a) cocatalyst.
摘要:
A paper web travels together with a support belt over two heatable drying cylinders and a guide roll between the cylinders, which together define a pocket. Vacuum prevails in the pocket upon operation. Above the pocket there is provided a sealing strip support with sealing strips fastened to it. The sealing strips are at the drying cylinders where they enter the pocket, and these strips counter the penetration of air into the pocket. The sealing strip support is moveable in various ways so that the distance between the sealing strips and the cylinder outer surfaces can be enlarged temporarily. The guide roll is hollow, is connectable with a vacuum source and has a perforated roll shell and is free of stationary inserted parts. A separate vacuum source communicates with extra perforations at axial end edge chambers of the guide roll for applying greater vacuum at the edge chambers than over the remainder of the roll.
