Abstract: A method and apparatus are provided for increasing the efficiency of treatment of a paper pulp slurry with chlorine gas, such as in the bleaching or delignification of deciduous wood chemical pulps, coniferous wood chemical pulps, and non-wood fibrous chemical pulps. Chlorine gas is intimately mixed with the pulp in a fluidizing mixer (14), the pulp preferably having a consistency of about 7-12%, and then is passed to a retention vessel (20). The discharge of pulp from the mixer to the retention vessel, and from the retention vessel to other treatment structures, is throttled by valves (30, 31) so as to increase the pressure in both the mixer and the retention vessel to above atmospheric, and preferably in the range of about 15-150 psig (1 to 10 bar above atmospheric pressure). The chlorine gas is added to the mixer through one more discs (53) of porous materials having pore sizes in the range of about 5-175 microns, such as porous ceramic or sintered metal discs. The increased pressure during the chlorine treatment, and the introduction of the chlorine gas in the form of minute bubbles, improve the solubility of the chlorine in the pulp slurry and thereby increase the efficiency of treatment. (Figure 1).

Abstract: 1. System for generating an artificial surge or swell in an ocean engineering experimental basin or dock, of the type having a beater constituted by a cylindrical float parallel to the rear wall of the basin, characterized in that the section of said float, i.e. the generatrix of said cylinder, has a substantially vertical rear side, i.e. substantially parallel to said rear wall, and a nose-shaped front side, and said float is associated with mechanical means imparting to it a horizontal alternating movement, the mean distance between the rear wall of the float and the rear wall of the basin being chosen in such a way that a resonance phenomen is created between the swell train produced by the oscillations of the water column between said walls and that created by the movement of the float, the superimposing of these two trains giving rise to a very high transfer function in a chosen swell period interval.

Abstract: This amplifier is used as line driver and allows a simple circuit configuration with additional reduction in power dissipation. This is due to the fact that the video output amplifier with emitter-coupled output is fed with a voltage which is positive with respect to earth and with a voltage which is negative with respect to earth and the operating point of the video output amplifier is set with the aid of a resistor between emitter and the negative supply voltage so that the voltage at the emitter with respect to earth becomes zero when the video signal is missing and, at the same time, such a current flows through the video output amplifier that a linear operating characteristic is ensured when it is driven with the video signal. In addition, the positive and negative feed voltage of the video output amplifier are generated by means of a single switched-mode regulator, the second supply voltage, which has the opposite polarity with respect to earth compared with the first output voltage of the switched-mode regulator, being obtained by inserting a voltage- stabilising circuit into the connection between the energy recovery diode and earth. <IMAGE>

Abstract: To improve the accuracy of self-calibrating A/D and D/A convertors in accordance with the principle of charge redistribution, a network subdivided into a weighted main and sub-converter network (MN, LN) and a calibrating and correction network (CN) is proposed which are designed to be capacitive. With binary weighting in each case, the capacitances of the three network areas (MN, LN, CN) are independent of one another with respect to values. The sub-converter network (LN) and the calibrating and correction network (CN) are coupled by means of coupling capacitances (CBK, CCK), the value of which is determined by the stray capacitants to be equalised and the desired calibration accuracy, to the common node (Kp) of the main converter network (MN).

Abstract: A data carrier has stored thereon a secret code and a user's biometric data. In using the data carrier, a data carrier terminal is first authenticated for access to data stored in the data carrier by reading a secret code from the data carrier in a manner known only to an authorized terminal, and then displaying the read secret on the data carrier terminal. If the user determines that the displayed secret code is correct, the user then presents a biometric feature which is read and compared to the biometric data stored on the data carrier. If the read biometric data matches the stored biometric data, then the user is authorized for further use of the data carrier on the data carrier terminal.
