Abstract: Device for operating a redundant multiprocessor system for the control of an electronic signal mechanism. A coordination processor (ER) assigns to each operation control area processor (BR1, BR2) an operating address ("07", "08"), transmits this by means of a module address ("87", "88") to the processors and provides the processors with the data required for process control. The operation control processors (BR1, BR2) communicate with one another and with the coordination processor using the operating addresses allocated to them. If the coordination processor (ER) detects the failure of an operation control processor (BR1), and if an operational standby processor (BRR) is available, then the coordination processor assigns the operating address ("07") of the failed processor (BR1) to this processor (BRR) by addressing it via its module address ("89"), provides it with the relevant data for process control and includes it as the new operation control processor in the processor network. The remaining operation control processors (BR2) communicate with the previous standby processor (BRR) using the operating address ("07") allocated to the previous operation control processor (BR1) and now to the previous standby processor (BRR) without being informed that anything has changed in the hardware of the processor network as a result of the failure of a processor (BR1) and the activation of a standby processor (BRR). <IMAGE>

Abstract: The invention relates to a method a device for feeding a mud-like catalyst mixture into a polymerization reactor. The catalyst mixture is fed from a container (12) into a batching space (23,24) of a feeder (10) connected thereto, from which channel the catalyst mixture is further fed by batches into the polymerization reactor by means of the pressure of a medium fed into said feeder (10). In accordance with the invention, after each catalyst batch fed into the polymerization reactor, the medium is essentially totally removed from the batching space (23,24) of the feeder (10) by leading the medium via an outlet channel (19b) into a space between two valves (26, 28) of on/off type before filling the batching space (23,24) with a new catalyst batch. The invention also relates to a device for realizing the method. <IMAGE>

Abstract: A method and apparatus provide for the continuous digestion of comminuted cellulosic fibrous material (e.g. wood chips) to produce paper pulp, with increased sulfidity. When black liquor is withdrawn from the continuous digester (32), instead of merely passing it to a pair of flash tanks (25, 26) and then to recovery, the concentrated liquor from a first flash tank is fed to a vessel (15) in which the comminuted material is slurried with a liquid. Since the black liquor remains in intimate contact with the chips for a significant period of time, the lignin in the chips is partly sulfonized. Ultimately the black liquor is replaced with white liquor or the like, and the separated out black liquor is circulated to recovery or disposal. A high pressure feeder (16) and a solids/liquid separator (36) are utilized.

Abstract: Caustic dezincing galvanized steel scrap. A dezincing plant includes a plurality of tanks (14, 16, 18) interconnected in series with steel scrap sequentially being moved through each of the tanks. The tanks (14, 16, 18) contain a caustic leaching solution including an oxidant with the leaching solution being circulated through each of the tanks (14, 16, 18) in a direction opposite to the movement of the scrap. Fresh scrap initially is exposed to a partially depleted leaching solution with the oxidant concentration of the leaching solution increasing as the scrap moves through the series of tanks (14, 16, 18). Leaching solution depleted of its oxidant is transferred to an electrolytic cell (22) where zinc is removed and plated as metallic zinc powder onto a cathode. The leaching solution is recycled by removing zinc. The chemistry of the leaching solution is controlled so that sufficient free caustic is present to prevent passivating zinc coating on the scrap. Oxidant is added to the recycled solution and the caustic concentration is adjusted, if necessary, to have a total caustic concentration of at least 5 M and the recycled solution is returned to the last tank (18). Compressed scrap bales are dezinced and ready for use as a melting furnace charge material. <IMAGE>

Abstract: The present invention relates to a method of controlling a fluid-flow regulating device, in which a pressure or pressure difference in a flow duct is maintained at a selected, substantially constant value, and in which the regulating device is driven via an operating unit through the influence of the actual fluid itself. The pressure or pressure difference is caused to act on a lever device in a manner to hold the lever in a position of equilibrium between its two terminal positions of rotation when the selected value of the pressure or pressure difference is reached. The operating unit is emptied essentially completely of fluid by the ejector effect provided by the removed fluid flow, when so required for control purposes, and the flow of fluid into an out of the operating unit respectively is controlled in response to the position of the lever device. The invention also relates to an arrangement for controlling a regulating device.

Granted: 1994-01-11
Abstract: ABSTRACT OF THE DISCLOSURE:     A method is disclosed of manufacturing a Z-directional compressibility gradient in a web of paper.  The method comprises the steps of coating the peripheral surface of a roll with a film of plasticizer.  An offset roll disposed adjacent to the roll is rotated such that the roll and the offset roll define therebetween a transfer nip so that a film of the plasticizer is transferred to the  offset roll.  The web is moved past the offset roll such that the web contacts the offset roll downstream relative to the transfer nip so that the film of the plasticizer is offset onto the web.  The web is then passed with the offset coating of plasticizer through a calendering nip such that between the offset coating of the web and the subsequent calendering of the web with the offset coating, the plasticizer is permitted to uniformly and controllably penetrate into the web such that the Z-directional compressibility of the web is controlled prior to the web extending through the calendering nip.

The first switch of the cascade comprises an L-type attenuator with series branch including a resistor and a shunt branch including a Zener diode. A bias network coupled to the attenuator and to the second switch of the cascade connection controls the diode bias for operation at a specific forward conduction when the second switch is open and for operation at a specific reverse bias condition when the second switch is closed for causing the attenuator to provide the plural functions of ( 1 ) enhancing the switch off-state attenuation, (2) providing over-voltage and overcurrent protection for input transients of either polarity and (3) providing a predetermined output DC level when the second switch is on for establishing the DC bias of a subsequent circuit, such as an amplifier, the DC bias so supplied being in a tracking relationship with DC power supplied to the subsequent circuit.

Granted: 2000-05-16
Abstract: The microfiltration of a turbid liquid, especially the microfiltration of a fermentation liquid to recover beer from a suspension containing excess yeast is controlled by measuring a flow velocity (v) and a pressure drop (.DELTA.p) and calculating from the flow velocity (v) and the pressure drop (.DELTA.p) by an apparatus-characteristic function F (v, .DELTA.p) containing the flow velocity (v) and pressure drop (.DELTA.p) as variables a value of concentration of the turbidity-producing solids in the retentate stream. The value of the concentration as thus determined forms an actual value which is compared with a setpoint value of the concentration to determine a difference which is used to control the rate at which the concentrate stream is withdrawn from the retentate stream.
