  • Patent number: 11248184
    Abstract: Processes and systems are provided for converting a carbonaceous feedstock into a reaction gas and a syngas, involving a step of pyrolysing and methanating the feedstock in a pyrolysis chamber to produce the reaction gas and a step of gasifying unconverted feedstock in the presence of a reactant to produce a syngas.
    Type: Grant

  • Patent number: 10294433
    Abstract: A process for extracting a condensable vapor from a supplied gas, comprising the steps of: i) condensing the condensable vapor by cooling the supplied gas at a condensing surface, such that the supplied gas is divided into at least one condensed fraction and a product gas; while ii) removing the at least one condensed fraction from the condensing surface by mechanical scraping means.

  • Publication number: 20130257302
    Abstract: A light-emitting diode (LED) bulb for use with a leading-edge dimmer includes a shell and an LED contained within the shell. A base is attached to the bulb for connecting the LED bulb to an electrical socket. A driver circuit is configured to provide current to the LED. The driver circuit has an input filter circuit that includes a first inductor. In response to the input filter receiving a switched AC voltage from a leading-edge dimmer set to dim at 50%, the first inductor is configured to saturate. In response to an undimmed AC voltage from the leading-edge dimmer, the first inductor is configured to not saturate. The input filter also includes a bridge rectifier connected to the first inductor.
