Abstract: An avionic system for producing the most economical engine thrust and airspeed settings in readily usable form during a jet aircraft flight is disclosed. The pilot inserts: the elevation of the destination airport; the zero fuel weight of the aircraft; the reserve fuel needed for the flight; the outside air temperature at the departure airport; and, a flight index number. The flight index number represents a chosen relationship between fuel costs and trip time-related costs. The system also receives data from various aircraft subsystems and sensors and uses the information it receives, and stored information, to produce signals representing the most economical engine thrust setting and airspeed for the phases of a flight. The thrust setting and airspeed signals drive bugs on thrust and airspeed indicators and/or used to control autothrottle/autopilot systems. The throttles and pitch attitude of the aircraft are controlled so that the indicator readings "track" the bug positions to cause the aircraft to follow the most economical flight path based on the chosen flight index number. Engine thrust limits are prevented from being exceeded by comparing calculated thrust values with stored engine thrust limit settings; and, using the maximum values to control the position of the thrust indicator bugs and the digital display. Still further, the system develops an aircraft idiosyncrasy factor (K) that is used to modify calculated thrust values in order to compensate for the drag and thrust peculiarities of the aircraft, zero fuel weight errors, etc.

Abstract: A converter is part of a modulator for phase modulation of data symbols and it converts the data symbols received during each time interval into sequences of phase values. Based on symbol correlation, the particular sequence of phase values is computed from an arbitrary rational modulation index, from a particular phase condition to which is assigned a first group of previously received symbols and which defines a phase condition number, and from a pulse response which extends over the present symbol and a second group of previous symbols. There exists a finite number of phase value sequences which are stored in digital form in a memory arrangement and which can be accessed by an address for each. Every arbitrary sequence of data symbols results in continuous phase changes. A calculation unit calculates a phase condition number during each time interval. The memory arrangement contains an access unit for creating the address which is determined by the particular data symbol, by said second group of previous symbols, and by the last phase condition number that was received from the calculation unit. <IMAGE>

Abstract: The subject channel interface circuit functions to provide a high speed interface between a processor and a data link, which link carries data messages having virtual addresses. The message handler is programmable and serves to translate the header portion of the data message from a virtual address into a hardware memory address, which is used to activate a specific location in the processor memory. The data portion of the data message is then directly inputted to this memory location (i.e., DMA) and the appropriate file pointers are reset. When a complete file is received and stored in memory, the message handler generates a processor interrupt. Thus, the subject message handler performs all the data receiving tasks, including file storage and linking, without requiring the involvement of the associated processor. All known prior art message handler circuits require extensive processor involvement in the data storage operation and thereby significantly reduce the effective data transfer capabilities of the link.

Abstract: In a procedure for washing cellulose in a drum a continuous web is conducted through a plurality of mutually separated washing zones and in the procedure the pure washing liquid is introduced at the washing step which is last in the direction of travel of the web. This liquid displaces suspension fluid contained in the web and the latter is urged with the aid of a drained fluid pipe system to a washing step located upstream in the web's direction of travel and the displaced suspension fluid repeats the displacement washing process performed by the pure washing liquid in the last washing step. This procedure is repeated until each washing step has received a flow of washing liquid. To utilize the concentration raising capacity of the washing procedure and apparatus, before discharging the pulp, part of the drained fluid pipe system is emptied and the drained fluid therefrom obtained is returned to an earlier washing step.
