Abstract: A system for natural language (NL) analyzis is provided which comprises apparatus and method. It has the capability to analyze NL expressions and to resolve ambiguities and present them to the user for verification of correct interpretation. 
     The invention is based on a language independent model of the contents of a data base. The model contains records of information defining entity types and rela­tions between such entity types. The model is created (customizing the system) by the user, and is stored as a conceptual schema. 
     The entities of the schema are linked or connected to natural language terms in a vocabulary. 
     The entities represent objects in the data base, and there is a link or connection between the entities and those objects of the data base. 
     The actual analysis of NL expressions is performed by a Natural Language Engine (NLE) in cooperation with an Analysis Grammar and the schema. The analysis results in an intermediate, language independent logic form repre­sentation of the input, which is paraphrased back to NL for verification, and if the input is a query, there is a translation into a query language such as SQL.

Abstract: A method for converting the thermal energy of a working medium into mechanical energy in a steam plant with a volume expansion engine in which is used the thermal energy of the working medium which changes, during the working cycle, its state of aggregation. The method provides for isobaric heating of the working medium up to a given temperature, feeding it to the engine, adiabatic expansion of the working medium and its condensation after the discharge from the engine with subsequent adiabatic compression. The heating and the adiabatic compression of the working medium before its feeding to the engine is effected up to the parameters corresponding to its area of critical state, whereas the adiabatic expansion of the working medium in the engine is effected from its area of critical state. The working medium used can be liquids whose difference of enthalpies between the points of critical and atmospheric pressures during the adiabatic expansion equals or exceeds the heat of vaporization.

IPC: G06F3/041
Filed: 1990-03-23
Abstract: A tablet transmits first radio signals intermittently to excite a tuning circuit built in an input indicator, and second radio signals generated from the tuning circuit are received by the tablet while the tablet does not transmit the first radio signals. A coordinate input device detects coordinate values of a position indicated by the input indicator. The coordinate input device and a display device are stacked. A timing of generating an indication data latch pulse in the display device is brought into agreement with a period of receiving the first radio signals from the tablet in the coordinate input device so that noise caused by the display data latch pulse of the display device may not generate while the second radio signals are being received by the tablet. Therefore, no noise infiltrates into the second radio signals received by the tablet, and it does not take place that the accuracy of detection of position is deteriorated by the interference. Further, no erroneous operation is induced.

Abstract: The disposal material is compacted to a fraction of its original volume while retaining its mixing structure and bond structure, is temporarily stored in this form, if necessary, and transported, and subjected to pyrolysis in this compacted form. All the pyrolysis products are immediately afterwards subjected to a high-temperature treatment under elevated pressure. The compacted disposal material can have been compacted into containers and is subjected to a low-temperature pyrolysis under pressure. In the environmentally sound processing of consumer goods, such as automobile wrecks or the like, large-volume portioning of the scrap material is carried out by division and/or compression before the intermittent introduction into the pyrolysis chamber. The solid, liquid and/or gaseous process products arising in the pyrolysis and containing pollutants are passed through one or more molten baths or smelted in an appropriate high-temperature furnace. The pyrolysis chamber can consist of a heatable pipe or rectangular duct or of a continuous furnace which takes a plurality of suitable containers with compacted disposal material.
