FitzRoy carefully documented his claims on how the storm glass would predict the weather: [3] [failed verification] A catalogue of storm glasses c. 1863. If the liquid in the glass is clear, the weather will be bright and clear. If the liquid is cloudy, the weather will be cloudy as well, perhaps with precipitation.
The standard United States National Weather Service rain gauge, developed at the start of the 20th century, consists of an 8 in (200 mm) funnel emptying into a graduated cylinder, 2.525 in (64.1 mm) in diameter, which fits inside a larger container that is 8 in (200 mm) in diameter and 20 in (510 mm) tall. If the rainwater overflows the ...
The gauge glass on a boiler needs to be inspected periodically and replaced if it is seen to have worn thin in the vicinity of the gland nuts, but a failure in service can still occur. Drivers are expected to carry two or three glass tubes, pre-cut to the required length, together with hemp or rubber seals, to replace the tubes on the road. [1]
Water-repellent glass (WRG) is a transparent coating film fabricated onto glass, enabling the glass to exhibit hydrophobicity and durability. [1] WRGs are often manufactured out of materials including derivatives from per- and polyfluoroalkyl substances (PFAS), tetraethylorthosilicate (TEOS), polydimethylsilicone (PDMS), and fluorocarbons .
The piston-cylinder apparatus is a solid media device, used in Geosciences and Material Sciences, for generating simultaneously high pressure (up to 6 GPa) and temperature (up to 1700 °C). Modifications of the normal set-up can push these limits to even higher pressures and temperatures.
The Hornet engine can be viewed as a 1928-design Morris Minor engine with two more cylinders. A re-design of both engines by Morris engines branch led to a less costly product for the Morris range, a side-valve replacement for the two-seater Morris Minor at first called the Morris Minor S.V. and announced at Christmas-time 1930.
