- 1868 'The Engineer' described a 30 HP steam engine, one of two supplied to the Madrid chocolate factory of Messrs Lopez (Chocolates Matías López?). See illustrations. An interesting feature was the method of governing. The governor modulated the position of a double-lobed variable profile cam, which controlled the stroke of a double beat steam inlet valve upstream of the steam chest.[1]
- 1871 Made crushing machinery. 'CAMROUX'S machine (by Gardiner & Mackintosh) operates by the continuous rotation of two angle-grooved circular discs of chilled cast iron, placed upon two shafts slightly inclined. There is a heavy fly-wheel. The machine will crush to any size, ores, quartz, granite, emery, &c.' [2]
