摘要:
The invention concerns a method and apparatus to produce a noble-gas plasma for excitation in optical emission spectrometry. The apparatus includes an hf generator feeding an oscillation circuit consisting of at least one inductor and one capacitor. The capcitor includes at least two capacitor plates which are so shaped and mutually arranged that they enclose a cavity in which the plasma may form.

A system for the automatic stacking, storage and withdrawal of packaged merchandise in large warehouses, the handling of the merchandise being controlled by a computer, so that the merchandise is withdrawn from shelves and loaded into passing transport containers. The shelves are subdivided into blocks for several product types. The merchandise pieces making up a single order are then ejected simultaneously at each block once the transport container has arrived at the preceding block, are collected and then simultaneously loaded into the transport container when the latter arrives at the proper block. After loading, the transport container is allowed to continue and the speed of the transport container is determined by the withdrawal, collection and loading times in such a way that the release of the merchandise of the entire warehouse occurs in a minimal time.

A microwave-heatable pressure reactor is provided for continuous or discontinuous treatment of liquid. The liquid is conveyed by means of a high-pressure pump in a pipeline which extends into a microwave-heatable zone of the pressure container into which it finally lets out through the free opening with a volume of pipe sufficient for the treatment of a desired quantity of liquid.

A device for heating substances under the development of high pressures in a microwave field is disclosed. Those parts of the device lying in the microwave field comprise material transparent to microwaves. The device comprises a pressure-resistant cylindrically shaped outer container and a cylindrically shaped inner container disposed inside the outer container. Both the inner and outer container is provided with a cover or a cap for closure thereof. An interspace is provided between an inner jacket surface of the outer container and an outer jacket surface of the inner container, which space is connected with a space outside the device via connecting channels. The interspace preferably contains a cooling media which is transported to and from the interspace and outer space via the connecting channels.

An apparatus for the simultaneous detection of several ranges of wavelengths of polychromatic light radiation, using one detector for each detected range of wavelengths, includes an interference filter which filters the range of wavelengths to be detected out of the polychromatic light beam, and optical elements for guiding the polychromatic light beam to be detected. The optical elements include a first system of mirrors in the path of the incident polychromatic light beam for collimating it in a hollow-cylindrical manner, one mirror of the first system of mirrors being located at the center of the collimated light beam. The optical elements further include a second system of mirrors in the hollow-cylindrically collimated light beam that deflects this light essentially perpendicularly to the conceptual surface of the hollow cylinder and radially to the longitudinal axis of thereof. Photo-detectors associated with the particular deflection mirrors are mounted opposite the second system of mirrors to receive the deflected light. A common interference filter is mounted in the path of the beam between the deflecting mirrors and the photo-detectors, the deflecting mirrors and the associated photo-detectors being pivotable about the interference filter.

An atomic spectrometer in combination with an atomizer apparatus for atomizing a test sample into an atomic state for analysis in the atomic spectrometer. The atomizer apparatus includes a heater for heating a sample to free individual atoms of the sample for atomic spectroscopy, a tube member containing a packing of an adsorbent, a reagent adsorbed on the adsorbent which reacts with a metal constituent in a sample to form a metal complex which adsorbs to the adsorbent at a first temperature and is volatile at a second higher temperature for desorption from the adsorbent, and a heater for heating the tube member.
