Abstract: A device (18) for producing index inserts has a processing station (21) by means of which processing procedures are undertaken on the index insert at each location which has the tab or later becomes a tab. Since this location in each case has a different separation from the upper or lower edge of the index insert from index insert to index insert within one set, the transport device (28) for the index insert is configured such that the index insert to be processed is stopped in the correct position and is subsequently transported further after the processing procedure. For this purpose, the transport device (28) manages without stop means, with the result that damage to the edges of the index insert is excluded. <IMAGE>

The measurement wiring (20) comprises pulse-width modulators (21,22,23), which form pulse-width modulated digital data (D L1 , D L2 , D L3 ) and negations (                D       L1         ¯           ,                D       L2         ¯           ,                D       L3         ¯           ) of said digital data out of each momentary value of the phase voltage of the three-phase network, a pulse width-height multiplier (26), and a control logic (24), by whose means the controls (Q 1A ,Q 1B ,Q 2A ,Q 2B , Q 3A ,Q 3B ) are chosen from said pulse-width modulated digital data (D L1 , D L2 , D L3 ) and from their negations (                D       L1         ¯           ,                D       L2         ¯           ,                D       L3         ¯           ) for the pulse width-height multiplier (26).

Abstract: An integrated optical, polarization-manipulating device, comprises a first waveguiding section (A) with a first guide (21), a second waveguiding section (E) with a second and a third optically decoupled and physically separated guide (28, 29) and an intermediary waveguiding section (C) for an adiabatic coupling between the first and the second sections (A, B). The intermediary section (C) comprises a polarization-sensitive asymmetric Y-branching device, provided with two mutually diverging intermediary guides (25, 27) coupled to the guides (28, 29) of the second section. At least one of the two intermediary guides (25) has a channel structure fragmented in the longitudinal direction. Coupling sections (B, D) for adiabatic couplings between guides of successive sections are provided, on the respective coupling sides, with the fragmented waveguide of a corresponding fragmented structure. 
Advantages: the device can be provided on non-birefringent materials; relatively simple to manufacture; and, in the case of the ridge-type guide structure, only one etching step required.

Abstract: An integrated circuit comprises a time-discrete oscillator (11) which generates numerical and time-discrete phase values of an oscillator signal. The circuit also comprises a time-continuous oscillator (120) which generates a time-continuous oscillation signal. The circuit comprises a phasemeter (132) which is coupled to the time-continuous oscillator in order to sample phase values of the time-continuous signal. The difference between the generated phase values and the sampled phase values is measured in a comparator circuit (140). This difference is utilized in a phase-locked loop in order to readjust the frequency of the time-continuous oscillator, so that the time-continuous oscillation is latched to the time-discrete oscillation. The phase comparison can thus be executed in a substantially time-discrete manner. As a result, the operational reproducibility of the circuit is very high. Because phase comparison is not restricted to a single, fixed phase point during the oscillation period, the phase locking exhibits hardly any jitter.

Abstract: The subject of the invention is a differential sample and hold circuit including a voltage/current convertor (1) having two differential inputs (E1a, E1b) and two outputs (S1a, S1b). According to the invention, each of these outputs is linked by way of an input multiplexer module (2a) to two interposed follower/holder modules (5a, 6a), in such a way that at any instant one of the follower/holder modules (5a, 6a) operates in follower mode whilst the other (6a, 5a) operates in holder mode. These two modules (5a, 6a) are linked to the output (S4a) of the sample and hold circuit by way of an output multiplexer module (7a). This structure makes it possible to double the sampling frequency without increasing the intrinsic speed of this circuit. Each follower/holder module (5a, 6a) includes an input load (10a, 11a) linked in parallel with a capacitor (C18a, C19a), an output emitter/follower transistor (T20a, T21a) and an interrupt cell (5-6a). Thus, the high-frequency performance of the circuit is improved. Application to digital signal processing. <IMAGE>

Abstract: A method for enabling a caller to obtain access to one or more services via a telephone network by speaking a password is described. The method begins by establishing at least one predetermined threshold value for a speaker verification signal. For each spoken character of the password, the method generates a set of parameters using a voice verification feature transformation. After entry and recognition of the password, the sets of parameters are used to generate a speaker verification signal for the password. Upon the occurrence of a predetermined call condition, the predetermined threshold value is adjusted to increase the level of security in the verification algorithm. If the signal verification signal for the password has a predetermined relationship with respect to the adjusted threshold value, the caller's identity is accepted. If not, the caller may be asked to answer certain personal questions before his or her identity is accepted.

Abstract: L'invention se raporte à un procédé pour enlever et récupérer les excédents de peinture vaporisée dans une cabine de peinture au pistolet avec lavage à l'eau. Ce procédé utilise une dispersion, soumise à agitation et mise en circulation, d'un composant à base de solvant organique dans l'eau qui recueille les excédents de peinture vaporisée. On laisse la dispersion contenant les excédents de peinture vaporisée subir l'opération de séparation des phases, pour former une phase organique et une phase aqueuse. La phase organique est ensuite traitée par exemple par distillation pour séparer les particules solides de peinture d'une partie de solvant organique qui contient le composant à base de solvant organique d'origine et les solvants organiques associés à la peinture. Cette partie de solvant organique peut être recyclée et réutilisée dans la dispersion en circulation et les particules solides de peinture peuvent être récupérées pour être utilisées ultérieurement, par exemple comme charge pour adhésifs ou pour être mises au rebut.
