In order to obtain extremely short valve switching times, at least a part of the magnetic circuit of the electromagnet 19 is laminated in that it comprises a plurality of thin sheet metal layers, which extend in the direction of magnetic flux therein, are contiguous one another and are electrically insulated with respect to one another. Lamination is preferably restricted to the magnet pot 23 whic...

An electronic control method for vehicles, wherein, when exercising control to start a vehicle from rest, the vehicle engine and clutch are controlled in a very low speed control mode, if the amount by which an accelerator pedal is depressed is less than a set value. If, however, the amount of accelerator pedal depression is greater than the set value, the engine and clutch are controlled in an or...

Installation allowing the adjustment of compensating filters without exposure to permanent irradiation. According to one possible embodiment, a radiological image is taken (source, brightness or luminance amplifier) and memorized in an image memory prior to being projected by the video projector onto the patient by through-crossing the filter, this filter having brightness absorption and X-ray abs...

Clearance adjusting means for rotating cutters, the cutter drums of which, firmly seated on a pair of supporting shafts having helical driving gears, possess longitudinal openings for receiving cutter bars, in which openings the latter can be clamped with the aid of fastening elements acting on clamping wedges and capable of being subjected to pressure, are to be improved such that the disadvantag...

A charged particle emission source structure comprising a needle-like electrode for emission of charged particles, a reservoir for a liquid metal for wetting the surface of the needle-like electrode, heat-generating support members for heating the liquid metal and holding the reservoir or the needle-like electrode, and an extraction electrode for applying an electric field as between it and the ne...

Dicaffeoylquinic acid can be separated and obtained as the free acid or salt of the latter from crude vegetable extracts with the aid of gel permeation chromatography on crosslinked modified polysaccharides, in particular on dextrans. If appropriate, the monocaffeoylquinic acids can simultaneously be isolated. To obtain the free acid(s), it is necessary to adjust the aqueous extract to a pH of aro...
