Patent CA-2324053-A1 (CA)
Title: Gasifier
Inventor: NEUFELD JAKE
IPC: C10J3/16
Filed: 2000-10-20
Abstract: A method and portable apparatus is described for the conversion of cellulose and other blomass waste materials through a pyrolysis and partial combustion sequence in a downdraft gasifier to produce a gas which can be immediately utilized to fuel an internal combustion engine in a generator set (genset). More specifically, the heat from the combustion of part of the cellulosic or other waste input is used to pyrolyze the remainder of the input to produce a mixture of permanent fuel gases. Particulates are removed (water scrubbers, filters) from the gas mixture which can then be used directly as a major part of the fuel to operate the internal combustion engine in the genset. All movement into, through, and out of the gasifier and purification train is controlled by the vacuum associated with the intake of the internal combustion engine, thereby ensuring a steady production of electricity.

Inventor: MOISEYEV NIMROD
IPC: G02F1/01
Filed: 1999-04-19
Abstract: An optical coupler, for coupling two optical waveguides (50, 60), and an optical switch based on the optical coupler. The indices of refraction of parallel sections of the two waveguides (50, 60) are reversibly perturbed periodically in space by imposing a mechanism (58, 68, 59, 69) to couple low order modes in the two waveguides via a high order mode common to the two waveguides. The waveguides are thus coupled with a beat length that may be five or more orders of magnitude shorter than it would be without the periodic perturbations.

Title: Operation of an upflow filter and non-buoyant filter bed in serles with a downflow filter and filter bed
Inventor: KIM ANNABELLE
IPC: B01D24/18
Filed: 1991-08-23
Abstract: A method of washing an upflow filter (12) between service runs employs a filter bed (26) having a non-buoyant particulate filter layer (56) through which influent to be filtered is directed in an upward direction, and through which liquid employed in the washing operation is directed in an upflow direction. A two-stage washing operation includes the steps of first directing a combination of air and liquid in an upflow direction through the filter layer (56) with the velocity of the liquid being less than the minimum fluidization velocity of the filter layer (56), for disrupting only some floc retained in the filter layer during a previous service run, and thereafter directing only liquid in an upflow direction through the filter layer at a velocity less than the minimum fluidization velocity of the filter layer for removing disrupted floc from the filter layer while leaving some floc attached to said particulate media of the filter layer. The process most preferably is carried out with a filter bed (26) including a coarse, particulate media flocculation layer (52) for distributing the flow of influent and promoting flocculation.
