Abstract: THE ABSTRACT OF THE DISCLOSURE           The present invention relates to a method and apparatus for controlling the operation of a multiple hearth furnace system for efficiently incinerating combustible materials, such as sludge in which the air of combustion is essentially all introduced at the bottom of the furnace to incinerate solid materials.  This control involves the following essential steps: scanning the temperature of two or more combustion hearths to determine which is the hottest hearth; controlling the temperature of the thus-determined hottest hearth at a predetermined temperature set point value; controlling the oxygen content of the system exhaust gas at least as high as the predetermined set point value; and maintaining the system exhaust temperature at least as high as the predetermined set point value.         The above controls are effected for modulating one or more operations consisting of controlling the combustion air flow to the bottom of the furnace, controlling the firing rate of the burner on the burner hearth or hearths above and/or below the thus-determined hottest temperature hearth and controlling the flow of afterburner air to the exhaust system in the case of operating the furnace system in the pyrolysis mode.  The present invention contemplates two modes of operation of the furnace system, i.e., the pyrolysis or excess air mode of combusting the combustible materials.  By this procedure and apparatus, it is possible to control the temperature profile of the furnace so as to operate under optimum conditions and to control the throughput or the feed rate of the combustible material, such as sludge, to the furnace on a more predictable and constant basis, since the hottest hearth is always known and its temperature maintained at a predetermined temperature value.

Abstract: METHOD OF CHLORINE DIOXIDE BLEACHING              ABSTRACT      Cellulosic pulp is bleached with chlorine dioxide in order to obtain maximum brightness per unit of chlorine dioxide bleach utilized. Sufficient caustic, such as sodium hydroxide, is added to the pulp and chlorine dioxide to maintain the pH of the pulp near or above the neutral level, e.g. pH 5.5 - 10.  The pulp is retained at that pH for a suitable retention time, and then acid, such as hydrochloric acid or chlorine gas, is mixed with the pulp to reduce the pH to a desired terminal pH, e.g. pH 2 - 4.5.  The pulp is then passed to a conventional retention tower where the chlorine dioxide reacts with the pulp at about 120° - 180°F for about 0.25 - 5 hours.

Abstract: ABSTRACT: Amplifier arrangement comprising a protection circuit.     A protection circuit for a power amplifier in which feedback is applied from the output (8) to the in-verting input (2) of the amplifier by a negative feedback network comprising a first resistor (R2), a second resistor (R1) and a capacitor (C2), comprises a voltage-current con-verter (12) whose input is connected to the output of the amplifier which is loaded by a load (RL) and whose output is connected to the junction point of the second resistor (R1) and the capacitor (C2). When the protection circuit is activated if the output transistors of the amplifier are loaded excessively for example due to short-circuiting of the load, the input voltage of the voltage-current con-verter (12), for low frequencies, is converted into a cur-rent which is re-converted into a voltage in the capacitor (C2), which voltage is added to the normal negative-feed-back voltage provided by the voltage divider comprising the first resistor (R2) and the second resistor (R1). This provides a strong negative feedback and hence a satis-factory protection. For higher frequencies the capacitor (C2) constitutes a short circuit, so that the negative feedback changes to the normal feedback, thus ensuring that the amplifier remains stable under all conditions. The am-plifier is then protected by the thermal cut-out which is normally present.       - Figure 4.
