Patent DE-3379045-D1 (DE)
Title: Process for the continual preparation of alkoxysilanes
Inventor: FISCHER PETER
IPC: B01J19/18
Filed: 1983-09-07
Granted: 1989-03-02
Abstract: A method for the continuous preparation of an alkoxysilane with hydrogen chloride contents of less than 20 ppm. In the method, the esterification is performed continuously in a reactor, and the raw esterification product is delivered to the top of a column. In this column, the reactant alcohol is vaporized and condensed at the top. The raw product drips from the top of the column to the bottom where it is collected as pure product. The method is suitable for the preparation of both tetraalkoxysilanes and of substituted alkoxysilanes. Partially condensed alkoxysilanes having a defined silicon dioxide content can also be made by this method.

Abstract: A tractor (10) includes a hitch (26) for pulling a ground-working implement. A hydraulic cylinder (34) is extensible and retractable to lower and raise the implement. A control syytem (50) senses operating parameters, including wheel slip, engine speed, draft force and implement or rockshaft position. Error signals are derived from the sensed wheel slip, engine speed and draft force and correspond set point signals. The error signals are combined into a composite or combined error signal. The larger of (a) the combined error signal and (b) a separately determined position error signal. is selected and converted to a pulsewidth modulated valve control signal which is applied to a control valve (42) which then actuates the cylinder to move the implement to reduce the magnitude of the selected error signal. Certain set point signals are derived from the corresponding parameter signals themselves.

Abstract: The device includes two polarising layers, two transparent confinement plates provided with electrodes, and a chiral liquid crystal confined between the plates in a "bookshelf" geometry. The phase of the liquid crystal is non-tilted and when a voltage is applied across the electrodes, tilting of the molecules of the liquid crystal results. This changes the polarising properties and the transmission of a light ray passing through the device. The non-tilted phase may be the smectic A phase or any non-tilted smectic phase adjacent to a tilted smectic phase. The induced tilt corresponds to either a lower- or a higher-temp. phase.
