Abstract: Nouvelles matières de revêtement ionomères acryliques à utiliser pour les reconstitutions effectuées à l'aide de composites selon la technique du sandwich. Il s'agit de systèmes constitués de deux pâtes de faible viscosité, qui peuvent être polymérisés soit par un procédé chimique, soit par la lumière. Les revêtements contiennent une matière vitreuse à base de fluorosilicates alumineux, qui contribue à minimiser la décalcification de la dentine et les caries secondaires. Ces revêtements adhèrent à la dentine et aux composites et sont radiopaques, ce qui permet le détection des défauts par radiographie aux rayons X.

Abstract: The circuit arrangement for the radio-frequency operation of a discharge lamp (L) connected to a low-voltage DC source has a self-oscillating push-pull converter with two power transistors (T1, T2) and a drive transformer (Tr2), a series resonant circuit in parallel with the output circuit, having a resonant inductor (L1) and a resonant capacitor (C3), as well as a power transformer (Tr1) for the transmission of the radio-frequency oscillation of the push-pull converter into the series resonant circuit. The primary winding (n1) of the drive transformer (Tr2) for the push-pull converter is connected in series with the secondary winding (n3) of the power transformer (Tr1) in the series resonant circuit. The output current thus flows via the primary winding (n1) of the drive transformer (Tr2), resulting in continuous matching of the transistor control to the load conditions. In addition, a device to vary the time constants of the control circuits of the push-pull converter is provided, by means of which the lamp power is stabilised in the event of variations in the operating voltage. The device preferably consists of a transistor (T3) whose emitter-collector junction is connected in parallel with the real total resistance of the control circuits. <IMAGE>

Abstract: An increase in the frequency and hence the output with which a pulsating steam jet pump can be operated is achieved in that the time taken for collapse of the steam bubble at the end of the working phase is shortened. For this purpose the pump tube is provided in the area suitable for this with a lining (6) of a material with high thermal conductivity and retention capability. The heat dissipation of the steam bubble is thereby accelerated, this heat resulting on the other hand in preheating of the liquid again flowing into the pump tube. In order to reduce heat losses to the surroundings on the other hand, this area of the pump tube is provided with an insulation (7). <IMAGE>

The frequency limitation parameters are used at the receive side to control a block filter function at the output of the decoder that outputs a decoded video signal, controlling this for postprocessing of the decoded video signal for the purpose of reducing the blocking artifacts.
