Abstract: A non-oxidative hair colouring composition, comprises yogurt or yogurt-derived material. The invention also provides a method of improving the colouring effects of non-oxidative hair colouring compositions, comprising application to the hair (during or after dyeing) of yogurt or a yogurt-derived material. The invention also covers use of yogurt or yogurt-derived material in a hair care composition for the purpose of improving the colouring effects of a non-oxidative hair dye. The invention can be put into effect by incorporating yogurt or yogurt-derived material into a hair care composition for use during non-oxidative dying of hair (i.e. a non-oxidative hair colouring composition) where it acts to improve dye deposition onto hair, or into a composition for use on hair after dyeing by a non-oxidative method, e.g. a shampoo or conditioner composition, to help maintain the colour of dyed hair.

Abstract: An Axminster carpet loom is described which has improved cutting means for severing pile lengths of yarn from the pile yarns. In the past these have been severed by a pair of knives which operate rather like a pair of scissors but they require skill and time to set up. The present improved means include a serrated edge blade and one or more knives mounted on weft-wise reciprocatable carriages, the cutting edges being reciprocated over the serrations in the blade which locate the pile yarns during the cutting operation. Such knives can be relatively quickly and easily removed and replaced by fresh or reground knives when they need sharpening and so the loom can quickly be started again.
