Abstract: Converter device for converting a PDM signal to an analog signal (OUT11/12). This device includes a main circuit comprising a conversion circuit (CC1) to which are supplied a PDM signal and control signals (CL1, CL2) which are dependent on supply voltages VDD and VSS, and an integrator circuit (LPF1). In a regulating circuit (CC2, LPF2, COMP2, PWM2) a reference signal (PDMR) is converted and integrated in the same way as the PDM signal and measurement signals (V21, V22) are generated which are function of the deviations of VDD and VSS from their normal value respectively. With these signals the respective control signals are compensated in such a manner that the converted signal (011/12) provided by the conversion circuit (CC1) becomes independent from these deviations.

Abstract: The process comprises three stages, namely an oxygen bleach which is optionally combined with a hydrogen peroxide bleach (EOP stage), an ozone bleach (Z stage) and a peroxide bleach (P stage). According to the invention, the residual oxygen content of the exit air from the Z stage is completely reacted in the EOP stage, and the effluent of the Z stage is used for dilution between the EOP and Z stages and/or for ash removal from the pulp after bleaching. It is advantageous in this case to control the temperature, the NaOH supply and the O2/H2O2 ratio in the EOP stage, so that the oxygen consumption at a constant conversion is adjusted to the residual oxygen content of the exit air from the Z stage.

Date Dec. 8, 1994A weight-adjusted underwater toy is disclosed having a somewhat lower specific gravity than water, and having its center of gravity located below and somewhat behind the volumetric center of the toy. The toy has a streamlined shape, like a fish, a sea animal, a swimmer, or a submarine. The model will follow a long glide curve similar to an approximately upside down ballistic path when flung into the water, and will always rotate into a position with its back up and its abdomen down. When rising, the location of the center of gravity will provide an inclined forward/upward position for the model, and horizontal side wings (fins or other details) will prevent a purely vertical rising movement by providing a forwardly directed momentum during a buoyancy movement. The weight adjustment takes place either by forming the model from a material which is heavier than water and is divided in two parts along a horizontal center section with an excavation in the top part in front of the center of the section surface, in such a manner that when joining the parts together, a sealed air pocket is formed, or by forming the model from a material which is lighter than water and has a heavier weight imbedded below and somewhat behind its volumetric center.
