Artificial Stone Now Made by New Methods
New processes render soft sandstone or limestone into hard impermeable material to a depth of about half an inch. The treated stone can be polished and cut for use in tanks and pavements. One method uses cement mortar with water glass and calcium chloride to create a hard silicate fill. A second method saturates with ammonium sulfate and water-glass, then wipes excess solution.
Engine Longs to Serve: Walking-Beam Iron Works Through Time
An English firm recalls its walking-beam engine built in 1854 with a four by eight inch cylinder and fourteen rpm under thirty psi. By 1898 it was compounded increasing pressure to 120 psi. In 1910 it became a triple expansion engine running at 300 psi and 430 degrees superheat. It once ran away fast enough to burst rope pulleys without serious damage.
