A dispensing device for dispensing powder foods or liquids has a scoop for containing the powder or liquid, and levelling means for levelling off the scoop contents, wherein the levelling means co-operates with a counter such that operation of the levelling means is adapted to advance the counter, the counter being characterised in that the counter may be reset to zero in a single step process.

A roundness measuring machine is described which measures the position of the surface of an object as the object is rotated on a turntable. The machine determines the circle which is the best fit to the measured points and converts the measurements to distances from the best fit circle. An improved algorithm for determining the best fit circle is used in place of the limacon fit. Calculated differences between the measured surface position and the best fit circle are corrected for the effect of ...

A measuring tape for measuring the distance between a first point and a second point. The tape has a flexible elongated blade with a tab fixed to free end of the blade for temporarily and removably hooking the free end of the blade to the first point. The tab extends in at least two directions transverse to a lengthwise edge of the blade at the free end of the blade. The blade has two sets of numbers imprinted thereon which correspond to units of measure. The first set of numbers is imprinted al...

A method and an equipment for determining components, particularly pH, pO.sub.2 and pCO.sub.2 in blood. In order to facilitate the determination of blood gases, one sensor is used for measurement of more than one component. The components are measured at the same measuring point, using an electrode based on antimony. The electrode potential is measured both with and without a known voltage applied over the electrode.
