Ronson Consumer Products Corporation was formerly based in Somerset, New Jersey.It is a producer of lighters and lighter accessories.. Zippo Manufacturing Company currently owns the related brands in the United States, Canada, and Mexico, and continues to produce Ronson lighters and Ronsonol fuel.
Several types of valve connections for propane, butane, and LPG containers exist for transport and storage, sometimes with overlapping usage and applications, and there are major differences in usage between different countries. Even within a single country more than one type can be in use for a specific application.
In the 1950s, there was a switch in the fuel of choice from naphtha to butane, [citation needed] as butane allows for a controllable flame and has less odour. [6] This also led to the use of piezoelectric spark, which replaced the need for a flint wheel in some lighters and was used in many Ronson lighters.
Butane (/ ˈ b juː t eɪ n /) is an alkane with the formula C 4 H 10. Butane exists as two isomers, n -butane with connectivity CH 3 CH 2 CH 2 CH 3 and iso-butane with the formula (CH 3 ) 3 CH . Both isomers are highly flammable, colorless, easily liquefied gases that quickly vaporize at room temperature and pressure.
Such diagrams are available in the speciality literature. [1] [2] [3] The same information can be depicted in a normal orthogonal diagram, showing only two substances, implicitly using the feature that the sum of all three components is 100 percent. The diagrams below only concerns one fuel; the diagrams can be generalized to mixtures of fuels.
Butane, like propane, is a saturated hydrocarbon. Butane and propane do not react with each other and are regularly mixed. Butane boils at 0.6 °C. Propane is more volatile, with a boiling point of -42 °C. Vaporization is rapid at temperatures above the boiling points. The calorific (heat) values of the two are almost equal.
LPG is composed mainly of propane and butane, while natural gas is composed of the lighter methane and ethane. LPG, vaporised and at atmospheric pressure, has a higher calorific value (46 MJ/m 3 equivalent to 12.8 kWh/m 3 ) than natural gas (methane) (38 MJ/m 3 equivalent to 10.6 kWh/m 3 ), which means that LPG cannot simply be substituted for ...
The Ronson was developed by the British Petroleum Warfare Department in 1940. [1] Having insufficient range it was passed over for British use but taken up by the Canadians for development. The "Ronson" was considered sufficient for use in the production of the "Wasp MkIIC" flamethrower variant of the Universal Carrier.
