A one-page column of British patent abstracts from the journal Engineering, 23 March 1900. It describes J. T. Ward and J. B. Curtis's bobbin with alternating wood and metal sections, meant to stop yarn being cut off instead of unwound. It also covers H. E. Ackroyd's machine that mercerises cotton or ramie threads while they are being doubled, using troughs of liquor, squeezing rollers and drag rollers.
