Abstract: An improved system for and method of precisely controlling the temperature at a predetermined location at a preselected temperature selected from a range of temperatures is described. The preferred system for carrying out the preferred method includes a mixing valve for separating a fluid stream into first and second component streams and adjustable in response to a first control signal so as to control the amount of separation of first and second component streams. The preferred system also includes a heater for heating the first component stream in response to a second control signal, a first evaporator for cooling the second component stream and a conduit for combining the heated and cooled component streams so as to provide a mixed stream to the predetermined location. The first and second control signals are provided as a function of the preselected temperature, the temperature of the heated first component stream, the temperature of the mixed stream and the temperature at said predetermined location. The system is also preferably provided with a second evaporator for recooling the mixed stream as it is recirculated if the temperature at the predetermined location does not drop below some predetermined level. The second evaporator provides partial recooling of the mixed stream when the temperature difference between the preselected temperature and the temperature at the predetermined location is below some preselected value and maximum recooling when   above the preselected value so long as the temperature at the predetermined location does not drop below the predetermined level.

Abstract: The invention relates to a process as well as to a device for influencing the coloured appearance of a coloured surface made up of at least three separate coloured inks in one printing operation, based upon densitometric measurements, where the influence on the coloration takes effect in dependence on a summation vector, which is determined by density value differences of the separate coloured inks in a colour space. In this way, it is possible to carry out the control and adjustment of the printing process, based upon the densitometric measurements, in dependence on the variations in the brightness and colour saturation, whereby a reduction in the print spoil level is obtained as a result of a better-targeted control.

Abstract: An apparatus for optically observing a wavefront from an object on real-time basis to determine an optical characteristic of an object and observe two-dimensional images at locations throughout the depth of the three-dimensional object using a four-wave mixing technique. Light from a pulsed laser (1) is split into two reference beams I and II which, after travelling over a substantially equal length optical path interfere with one another in a nonlinear optical element (12). The light from the laser (1) is also split into an object beam III which interferes with an object and then, light modified as a result of its interference is collected and directed to the non-linear optical element (12) again after travelling over a substantially equal length optical path to the reference beam I, II. The object beam III interferes with the reference beam I, II to produce a phase conjugate which is returned along the path of the object beam. A beam splitter (9) directs the phase conjugate beam onto an image observation device (10).

Abstract: A data compression method and apparatus particularly suitable for use in electrical power line fault data recorders. The system performs both gain compression and frequency compression. For gain compression, a predetermined number of samples are analyzed to determine a gain setting common to each sample in the set of samples. A reduced data string consisting of a gain code and data words having fewer bits than the input words are transmitted as a compressed data string. For frequency compression, a sample set representing the input signal is decimated until there remain only a sufficient number of data samples to satisfy the Nyquist criterion for the highest frequency component of interest. The frequency compressed output data string comprises a frequency code representing the highest frequency of interest followed by the set of decimated data samples.

Abstract: The invention relates to a dipole curtain antenna for radiating short-waves, in which the dipoles are arranged in columns and rows. Dipole curtain antennas are known. They consist of horizontally polarised dipoles which are arranged in a vertical plane, to be precise in columns and rows. They are used for producing short-wave radio links with the aid of the ionosphere. The requirement exists to supply different destination areas in successive periods of time with one antenna, or to reach the same destination area when the ionosphere is at different heights. This necessitates a change to the vertical polar diagram and, since the number of dipoles determines the type of directivity of the polar diagram, it is intended to create a dipole curtain antenna (e.g. a 4/6) with a high number of dipoles in which it is intended that different operating modes should be possible, e.g. 2/2, 2/4 or 4/4, without the polar diagram having been distorted. It is also intended to be possible to change the polarity of some dipoles. According to the invention, the dipole curtain is constructed of individual dipole modules, each dipole module consisting of two horizontal and/or two vertical dipoles and the vertical interval in each case between adjacent dipoles being less than  lambda /2 inside the module and greater than  lambda /2 outside the module, and the horizontal interval from dipole centre to dipole centre (centre interval) in each case between adjacent dipoles being equal to lambda /2 inside the module and greater than  lambda /2 outside the module, the vertical interval between adjacent dipoles preferably being approximately 0.4 lambda  inside the module and approximately 0.6 lambda  outside the module, and the centre interval between adjacent dipoles outside the module being 1.2 lambda .
