Abstract: A hand-held colorimetric device (101) suitable for use by blind or colour-blind individuals to determine the colour of a surface-under-test (SUT), for example of a fabric, has an aperture (110) which, in use, is covered by the SUT (113) whose colour is to be determined. Six LEDs (115A, 115B, 116B, 117A and 117B) arranged in pairs (115A/115B, 116A/116 B, 117a/117B) emitting red/orange, green, and blue light illuminate the SUT and diffuse reflections therefrom containing red/orange, green, and blue spectrum sample values are used to determine the luminous reflectivity and chromaticity values for the colour of the SUT. The measured values are compared with colorimetric values of reference surfaces to determine the colour of the SUT. The colorimetric device may output the name of the colour aurally.

Abstract: A grinder vehicle for removing traffic markings from an underlying roadway surface is provided. The grinder vehicle includes a drive unit having a frame assembly supported by a plurality of wheels and a drive unit engine that drives at least one of the plurality of wheels. A drive shaft is connected to the drive unit engine. A grinder head assembly is connected to the frame assembly of the drive unit and is driven by the drive shaft of the drive unit engine. The grinder head assembly includes a plurality of grinder heads for removing the traffic markings from the underlying roadway surface.

Abstract: The application discloses Sz. pombe yeast cells which have been modified so that a F-Protein Coupled Receptor (GPCR)-regulated signalling pathway is derepressed during the mitotic phase of cell growth. Isolated nucleic acid molecules encoding constructs used to make the yeast cells, uses of the cells and nucleic acid molecules to study GPCR pathways and to isolate compounds which effect in such pathways are also disclosed.

Abstract: Inks are formulated for forming anode and cathode catalyst layers and applied to anode and cathode sides of a membrane for a direct methanol fuel cell. The inks comprise a Pt catalyst for the cathode and a Pt—Ru catalyst for the anode, purified water in an amount 4 to 20 times that of the catalyst by weight, and a perfluorosulfonic acid ionomer in an amount effective to provide an ionomer content in the anode and cathode surfaces of 20% to 80% by volume. The inks are prepared in a two-step process while cooling and agitating the solutions. The final solution is placed in a cooler and continuously agitated while spraying the solution over the anode or cathode surface of the membrane as determined by the catalyst content.
