Abstract: A leak-detecting probe (10) according to the float principle, which is to be positioned in the intermediate space (12) between the outside of a container (14) accommodating the fluid to be monitored and the inside of a collecting container or a collecting trough (18) surrounding the container (14) and has a probe tube (28), which can be put into the intermediate space and is perpendicular in the positioned end position and in the inside of which at least one magnetically operable switch element is arranged which is part of an electronic monitoring circuit, and at least one float (32) which is guided on or next to the probe tube in a displaceable manner, contains a switching magnet, floats on the emerging leakage fluid in the event of a container leak and, when a predetermined level of the leakage fluid in the intermediate space (12) is reached, changes the switching state of the switch element and thereby triggers a warning signal in the monitoring circuit. The probe tube (28) is mounted so as to be seated on the base of the intermediate space (12) and is relatively short compared with the height of the intermediate space (12) measured in the perpendicular direction but is long enough for the guidance of the float (32) into a floating position triggering the electrical switch element. A cable (24) containing the electrical connection leads for the switch element or switch elements is led out of the top end of the probe tube (28) in a sealed-off and strain-relieved manner, its length being such that it can be led out of an opening (20) at the top side of the intermediate space (12).

Abstract: A high-speed document verification system includes a document which is printed with a pattern having a predetermined arrangement of different reflectivity due to varying densities, line resolutions, or fluorescence. The arrangement represents information about the document. The document is fed into a high-speed document scanner sensitive to the varying ink densities or line resolutions. A graphic image of the document is produced by the scanner and this image or a graphic file of the image is checked to see if the proper pattern exists. A comparison unit, such as an optical character recognition system may be used to compare the scanned document's image with known density arrangements of valid documents to determine what information, if any, is represented by the arrangement. The graphic image may be sent to an operator's work station to be visually checked rather than being compared by the comparison unit or the image may be sent to the operator after it has been rejected by the comparison unit.

Abstract: 2.1 Magadiite is a rare natural mineral, an aluminium-free hydrated sodium silicate having a sheet structure of the composition Na2O.14SiO2.9H2O. The processes developed for the preparation of magadiite have long crystallisation times and hence low space-time yields. 2.2 It is intended to provide an industrial process for economical, environment-friendly production of magadiite. The process is characterised in that the following molar ratios are present in the reaction mixture:     Na2O/SiO2 = 0.04 - 2   H2O/SiO2 = 2 - 100 and the hydrothermal crystallisation is carried out in two stages, the first stage comprising the temperature range from 423 K to 598 K for 1 to 20 minutes and the second stage comprising the temperature range from 323 K to 423 K for 1 - 100 hours. 2.3 The sheet silicates prepared by the process according to the invention are preferably used as ion exchange material, as catalysts or catalyst components, as adsorbents, as carrier material for catalytically or pharmacologically active substances and as fillers and/or pigments.

Abstract: A local oscillator (10) is maintained within a small frequency window around any one of a number of reference frequencies so that it can lock onto the frequency of an incoming color burst (CHRM). The oscillator (10) is a current-controlled oscillator. Its control input is switched (32) to a capacitor (20) charged to a state which will, when connected to the oscillator control input, result in the correct oscillator frequency (Fo). The connection to this capacitor (20) is made when the charge on either one of two control capacitors (22,24) exceeds a threshold value. The threshold values are exceeded when the local oscillator frequency (Fo) is respectively greater than or less than the reference frequency (Fr) by a predetermined frequency difference.

Abstract: In a multisite radio frequency simulcasting transmission system involving microwave-multiplex distribution paths to several transmitting sites, each path including manually settable amplitude and time delay devices for equalization of the modulation in signal overlap areas among the various transmitter sites, an automatic simulcast alignment device is included in each distribution path whereby transmissions between a control point and each site transmitter are periodically tested and each path is compensated for amplitude and time delay variations to thus maintain equalized amplitude and time of arrival of the modulation in the transmitter site overlap areas. Thus, the instantaneous distribution of the FM modulation sidebands is maintained to be ideally identical in the signal overlap areas.

Abstract: This invention forces a multi-spectral line laser to operate on a single spectral line by modifying the gain of the medium instead of the standard approach of modifying the loss of the cavity. The spectral line selected by the system of the present invention is always the same identical spectral line. There are no ambiguities in knowing which line has been selected as there are with other methods. The invention involves a system for using more than one type of gain media within the laser cavity. Each medium gives rise to a distinct set of spectral line frequencies at which it has gain. Only occasional coincidences will occur at which spectral lines from two or more media fall within a linewidth of each other. Where these coincidences do not occur, the gain for a spectral line is only proportional to the amount of the individual medium present and will be below threshold. Where the coincidences do occur, the total gain is proportional to the total amount of gain for all of the involved media and the line will lase. Spectral lines that are within one operating linewidth of one another may be achieved by the use of two different types of gain media within the laser cavity. The most promising embodiment of the present invention is to use the same type of gain media but with different isotopes, which would, in many but not all cases, allow a physical mixing of the media within the resonant cavity. Each medium or isotope gives rise to a different and distinct set of spectral line frequencies at which the system has gain. Only occasional coincidences will occur at which spectral lines from two or more media fall within a linewidth of each other. Where these coincidences do not occur, the gain for a spectral line is only proportional to the amount of the individual medium present and will be below threshold. Where the coincidences do occur, the total gain is proportional to the total amount of all the involved media and the line will lase.
