Abstract: The system according to the invention provides for the insertion, in an ultrafiltration plant, of probes suitable for detecting the istantaneous value of a plurality of variables, such as, e.g., temperature, turbidity, permeate quantity, flow speed, pressure, chlorine concentration, pH. 
     Said probes are connected to a microprocessor which analyzes and elaborates the istantaneous data by comparing them with corresponding threshold values which are pre-established for a given process phase, said threshold values being divided into three different levels, namely:
     - normal operation;   - alarm in operation: operative risk;   - system shutdown.   
     According to the invention the microprocessor, which is on its turn connected to an electronic computer, is programmed in such a way as to analyze all the possible combination of values which may be operatively intersected, and to allow the plant to be held into operation even if some values would fall within the limit of operative risk, provided that the other correlated parameters would compensate this kind of "breaking".

Abstract: The invention relates to a method and a device (14) for determining a fundamental current space vector (is1) of a measured stator current space vector (is) of a converter-supplied induction machine (2). According to the invention, a harmonic-model current actual vector <IMAGE> is determined as a function of a control voltage vector (u<*>s1) and of a measured stator voltage space vector (us), which harmonic-model current actual vector is automatically adjusted in accordance with a harmonic current actual vector (iosw) as a function of a proportionality factor (k) which is calculated from the harmonic-model current actual vector <IMAGE> and from a fundamental current space vector (is1). A fundamental current space vector (is1) of a measured stator current space vector (is) can thus be detected quickly, with a high frequency bandwidth, in converters having a low switching frequency. <IMAGE>

Abstract: Spent nuclear reactor coolant system decontamination solutions are process to remove the radioactive burden and to separate metallic impurities using ion exchange resins within an electrochemical cell. The application of electric current to the electrochemical cell causes hydrogen ions to replace captured cations held on the ion exchange resin, thereby regenerating the resin for subsequent processing. The displaced cations migrate into the cathode compartment. The radioactive burden and metallic impurities are removed from the cathode compartment of the electrochemical cell. In a particularly preferred process, the cations are plated onto the cathode and diposed of as solids.

Abstract: A high concentration of diatomic molecules is caged in a host crystal by a crystal growth process, in which all other internal degrees of freedom of the diatomic molecule, except the vibrational, are frozen. Such a system provides an efficient mid-infrared, solid-state laser that can be pumped by a laser diode. Other uses include magnetic (Faraday) rotators, electro-optic switches, and Q-switches. The crystal growth process employs Czochralski-type or Bridgman-type processes under high pressure to introduce the diatomic molecule into the host lattice at a temperature slightly above the melting point of the host crystal, followed by slow cooling.

Abstract: The invention relates to an artificial hip cup which consists of a metallic outer shell (1) with anchoring pins (11, 12, 13) and of a metallic inner shell (2). With reference to an axis (17) of assembly, the inner shell (2) bears at the pole in the axial direction on a shoulder (14) and bears radially with a centring pin (4) in a bore (16). The inner shell (2) has at its outer edge a play (5) with respect to the outer shell (1) and bears elastically on the latter via a damping ring (3) secured thereon, engaging radially in a groove (7) in the outer shell (1). By virtue of the fact that the wall thickness (18) of the outer shell (1) is less than a fifth of the wall thickness (19) of the inner shell (2), the outer shell (1) can follow slight displacements of the bone tissue. In addition, the elastic outer shell (1) compensates for stresses with respect to the bone tissue upon transmission of force peaks. The damping effect is strengthened by the elastic damping ring (3) and by a shoulder (14) designed elastically in the direction of the axis of assembly (17).
