Abstract: A method for producing hydrocarbons from polymer waste includes: A) heating pre-crushed polymer waste in the presence of a mixture of liquid hydrocarbons to a temperature sufficient to convert at least one target polymer from the polymer waste to solution, but a lower transition temperature to solution for the remaining components of the polymer waste, to produce a polymer-containing mixture including a solution of at least one target polymer in the liquid hydrocarbon mixture, and B) catalytic cracking of the polymer-containing mixture in the presence of an ultrafine catalyst at a temperature from at least 360° ° C. to produce a mixture of liquid and gaseous hydrocarbons.

Abstract: A method of generating a help file used commonly in different models of image forming apparatuses includes reading a setting value indicating a function provided by one of the image forming apparatuses, setting a field value of a parameter corresponding to the read setting value, and configuring a help message based on the set field value of the parameter. A system to generate a help message includes a configuration module to determine identification information regarding each of a plurality of functions of an object included in one of software versions and characteristic data regarding the software version, and a universal help file including function descriptions for all of the software versions provided in a computer, receiving the identification information and the characteristic data, and generating the help message regarding the object using the function descriptions according to the identification information and the characteristic data.

Abstract: A method and apparatus are provided for adaptively generating a tooltip to be displayed in association with an object, such as a push button or a check box, according to the state of the object. The method comprises determining a current state of the object; and generating a tooltip to be displayed in association with the object according to the current state of the object. Since a tooltip is adaptively generated for an object included in a GUI and is automatically displayed in association with the object. Thus, it is possible to conveniently control a device with reference to the tooltip without the need to additionally refer to instructions regarding the GUI.
