Patent CA-2609977-C (CA)
Inventor: WUENNING JOACHIM A
IPC: C10J3/66
Filed: 2006-06-02
Granted: 2013-08-06
Abstract: The fixed-bed gasifier in accordance with the invention operates with a solid material batch that is perfused by air and/or steam in opposing direction. Compared with the resultant pyrolysis coke batch, the actual pyrolysis zone is thin enough so as to result in a material dwell time in the pyrolysis zone of only a few minutes, while the dwell time of the pyrolysis coke in the pyrolysis coke layer may last up to several hours. The pyrolysis occurs in an allothermic manner.  High-energy low-dust and low-tar gas is formed. The process control can be automated in a reliable manner. The exhaust of reaction gases and pyrolysis gases occurs through the heating chamber, whereby the last tar components are eliminated.

Title: A hearing aid and a method of processing input signals in a hearing aid
Inventor: KLINKBY KRISTIAN TJALFE
IPC: H04R25/00
Filed: 2005-10-11
Granted: 2012-05-08
Abstract: A hearing aid comprises two microphones, directional processing means (Dir1, Dir2) for combining the respective audio signals to form a spatial signal, a beamformer (35) for controlling the directional processing means to provide adaptation of the spatial signal, and means (LFB1, LFB2) for boosting low frequencies of the spatial signal. A feedback estimator generates a feedback compensation signal (7a, 7b), which is combined with the boosted spatial signal. By applying feedback compensation only after directional processing and low frequency boosting, the device avoids interference by the feedback estimator with the function of the beamformer. The invention also provides a method of processing signals in a hearing aid.
