A high frequency pulse generator, a distributed parameter coupling line, a sequential pulse variable voltage ignition system using a standard HMI lamp or a specialized ultra high frequency HMI lamp to provide a high Color Rendering Index, to reduce or eliminate audit lamp and igniter resonance and provide for a wide range of color correction from 7000&#xb0; Kelvin to 3000&#xb0; Kelvin from a standard HMI lamp.

High frequency programmable pulse generator lighting apparatus, systems and methods

A mixing device, especially for a fermenter, capable of dispersing gas in a broth therein, in which a number of propeller mixers are provided on a vertically extending shaft. The lower propeller mixer is a gas dispersing mixer having a hollow hub and open channels on the blades extending from this hub and tapering outwardly. At least one intermediate propeller mixer has some blades shorter than others and of reverse flow direction, some blades having baffle bars on trail edges thereof. The upper propeller mixer has the longer blades without channels and flow modifying elements.

Complex mixing device for dispersion of gases in liquid

Complex mixing system with stages consisting of propeller mixers of high diameter ratio, where the blades are provided with flow modifying elements, whereby the energy proportions spent on dispersion of the amount of gas injected into the reactor, homogenization of the multi-phase mixtures, suspension of solid particles, etc. and the properties corresponding to the rheological properties of the gas-liquid mixtures and to the special requirements of the processes can be ensured even in extreme cases. Open channels (5) opposite to the direction of rotation are on the blades (4) of the dispersing stage (2a) of the propeller mixers (2) fixed to a common shaft, where the channels (5) are interconnected with gas inlet (7). The angle of incidence of a certain part of the blades (4) of mixing stages (2b, 2d) used for homogenization and suspension is of opposite direction and the length is shorter and/or the angle of incidence is smaller than those of the other blades. Baffle bars (8) are on the trailing end of the blades on a certain part (2c) of the propeller mixers used similarly for homogenization and suspension, and/or auxiliary blades (12) at an angle of max. 20.degree. to the blade wings are arranged above or below the trailing end of the blades (FIG. 1 and 6).

A linear overpressured thin layer chromatographic apparatus comprises a base plate 3 supporting a sorbent layer 1 over which a membrane 4 is filled. The membrane 4 is externally pressurized by a fluid medium 10. A transparent cover plate 5 is fitted over the membrane 4, and there are sealed inlets 6, 7 passing through the cover plate 5 for the introduction of the mobile phase and the samples.
