Abstract: A method of gasifying carbonaceous material is described. The method comprises a first step of pyrolyzing and partially gasifying the carbonaceous material to produce volatiles and char. The volatiles and the char are then separated and, subsequently, the char is gasified and the volatiles are reformed. The raw product gas is then finally cleaned with char or char-supported catalysts or other catalysts.

Abstract: A method of determining a characteristic of a power transformer is provided. The power transformer has an input current, an input voltage, an output current and an output voltage. The method comprises measuring the input current and a voltage difference between the input voltage and the output voltage of the power transformer while the power transformer is in use within a power distribution network. Information that is indicative of at least one property of a test locus plot from the measured input current and voltage difference of the power transformer is derived and compared to information that is indicative of at least one property of a reference locus plot associated with a reference power transformer. From the comparison, it is determined whether a characteristic of the power transformer differs from that of the reference power transformer.

Abstract: The present disclosure provides an apparatus for sorting a particulate material. The apparatus comprises a receiving portion for receiving the particulate material having a particle size within a predetermined range of sizes. The apparatus also comprises a distributor for receiving the particulate material at an upper end thereof and having a sloped distribution surface along which, in use, the particulate material passes substantially by gravity. A surface area of the sloped distribution surface increases towards a lower end of the distributor to facilitate a monolayer feed stream of the particles exiting and falling from a lower end of the distributor distributed as a curtain-like stream of particles. The apparatus further comprises a magnetic element for generating a magnetic force that is directed such that the particles of the falling feed stream that exit the lower end of the distributor have pathways that depend on magnetic properties of the particles.

Abstract: A pyrolysis plant 20 comprises a grinding pyrolyser 22, being a machine or apparatus in which both particle size reduction and pyrolysis occur simultaneously. Plant 20 also comprises a bin (hopper) 30 for holding wet particulate biomass feedstock. Chute 32 leads from the bin 30 to a biomass dryer 34 which reduces moisture content of the feedstock as low as possible, e.g., to below about 10. Dried feedstock is conveyed from dryer 34 via line 36 to a dried biomass feedstock hopper 38. Dried feedstock is fed from hopper 38 into a chute 40 which leads to an inlet trunnion 42 of grinding pyrolyser 22. A discharge trunnion 44 of grinding pyrolyser 22 leads to a char holder 60 for collecting char particles and a condensation train 62 for condensing vapour generated by the pyrolysis to produce oil.

Abstract: A method of determining a location (x,z) of a subsurface boundary (38) of a body (30), comprising providing a wave source (34) and a receiver (36) on a surface (32) of body (30); measuring a travel time of a wave from source (34) reflected to receiver (36) via the boundary (38); and determining horizontal slowness of the wave at the receiver (36) and/or the source (34), as well as the curvature of the wave at the receiver or the source. The location (x,z) is determined on the basis of the measured travel time and the determined horizontal slowness(es) and/or curvature of the wave. The wave may be a seismic wave for geophysical surveying purposes, or an ultrasound wave for medical diagnostic purposes.

Abstract: This invention concerns the testing of surveillance camera installations. In particular, the invention involves an automatic testing system for surveillance camera installations, and a method for testing. The invention involves receiving test or “probe” images from at least one camera in the installations. Storing a reference image from at least the one camera. Comparison of the probe image with a reference image from the same camera, and production of an output when maintenance is required for that camera. The comparison involves the steps of: Extracting salient features from both the probe and reference images. Calculating matching factors between the salient features extracted from both images. And, computing a decision about whether maintenance is required from the matching factors.
