Abstract: Abstract An application program includes an action processor which receives messages containing user syntactic actions.   These actions are translated into semantic commands.  The semantic commands are sent to a command processor for execution.    The preferred embodiment of the computing system additionally includes an agent engine.  The agent engine may be used to perform many functional.  It may be used to receive semantic commands from an application, and to record the sematic commands for later playback.  It may be used to send semantic commands from a task language file to  an application program for execution by the command processor.          It may be used to intercept semantic commands sent from action processor to the command processor. After the command is intercepted, the agent engine may be used to allow the semantic command to be executed, to prevent the semantic command from being executed.

Abstract: ABSTRACT OF THE DISCLOSURE         A  method of producing an elliptic core type polarization-maintaining optical fiber comprises the steps of providing a glass rod comprising a cladding glass layer around the periphery of a core glass layer, the cladding glass layer having a softening point higher than the softening point of the core glass layer, removing two side surface portions of the glass rod by machining along the axial direction of the glass rod to form a machined rod. noncircular in cross section,   outside  depositing fine silica glass particles on the periphery of the machined rod, followed by sintering to provide a support glass layer having a softening point higher than the softening point of the cladding glass layer, and drawing the thus obtained glass rod body as an optical fiber preform. Since the portion for constituting the core of the optical fiber is formed by machining, the core is permitted to have a high ellipticity.  An optical fiber with the desired size and birefringence index is obtained by regulating the conditions of production.

Abstract: The present invention relates to a method and apparatus for pumping high consistency pulp, which invention is especially suitable for pumping high consistency fiber suspensions in the pulp and paper industry. One of the problems in the prior art techniques has been the difficulty of bringing high consistency pulp to the impeller of the pump or like, because high consistency pulp tends to form strong fiber network, which stops the pulp flow. A method has been developed as a solution to the problem, in which liquid is discharged from pulp during the pumping process and the liquid is fed back to the pulp to be pumped upstream of the pumping. This method is enabled by an apparatus, in which at least part of the surfaces of the pump (1) are arranged with filter surfaces (6, 7, 8, 9, 10), through which the liquid separated from pulp is returned either directly in front of the suction opening (11) of the pump (1) or to some other suitable place in the mass tower.
