Title: The assessment of colour in diamonds and other gems
IPC: G01N21/87
Filed: 1979-10-09
Abstract: A method of assessing the colour of a diamond or other gem is provided which comprises aligning the table of the gem normal to the axis of light projected from a source, and making the axis of the light co-linear with an axis of symmetry of the gem which is normal to the table, projecting the light of a given single wavelength at the gem and determining the proportion of incident light transmitted by the gem, repeating this determination for different wavelengths of light over the visible wavelength range so as to obtain a transmission spectrum and calculating the chromaticity co-ordinates therefrom. Using the method it is possible to obtain a wholly objective assessment of the colour of the gem.

Patent GB-2036333-A (GB)
Title: Fluid flow meter
IPC: G01F1/28
Filed: 1979-11-15
Abstract: A flow meter, suitable for measurement of speed of water flowing in a stream, comprises a support member 13 rotatable against a biasing force by the force of flowing water acting on vanes 14, 15 carried by the support member. A first vane 14 is secured directly to the support member and a second vane 15 is mounted pivotally,on the member such that it can turn freely through a predetermined arc and only when this is exceeded does the vane bear on the support member. Preferably the second vane is more sensitive to the force of water flow than the first vane. The use of two vanes increases the sensitivity at low flow rates and extends the maximum flow rate that can be measured. The vane 15 may have a curved extension to increase its sensitivity. <IMAGE>
