EXTINGUISHING DEVICES

F23Q 25/00

Mechanical igniters (lighters containing fuel F23Q 2/00; matches C06F)

using friction or shock effects

on a part moved by the fuel-controlling member, e.g. by a tap on a gas cooker

Portable igniters

Lighters containing fuel, e.g. for cigarettes

Lighters with liquid fuel

with cerium-iron alloy and wick

with friction wheel

with ignition by spring action of the cover

with other friction member

with cerium-iron alloy without wick

with cerium-iron alloy and torch ignited by striking or pushing

Lighters with gaseous fuel, e.g. the gas being stored in liquid phase

167

with adjustable flame [3]

173

Valves therefor (valves in general F16K) [3]

Lighters with solid fuel

with cerium-iron alloy and friction wheel

with cerium-iron alloy and tinder

with ignition pills or strips with inflammable parts

combined with liquid-fuel lighters

Lighters characterised by electrical ignition of the fuel (lighters with electrically-produced sparks but without fuel F23Q 3/00)

Lighters characterised by catalytic ignition of fuel (catalytic igniters without fuel C06C)

Lighters characterised by being combined with other objects (combinations with smokers' equipment A24F)

Make-and-break ignition, i.e. with spark generated between electrodes by breaking contact therebetween (specially adapted for internal-combustion engines F02P 15/00)

Incandescent ignition; Igniters using electrically-produced heat, e.g. lighters for cigarettes (circuits therefor H01T 15/00); Electrically-heated glowing plugs

for igniting solid fuel

with fans for transfer of heat to fuel

structurally associated with fluid-fuel burners (lighters containing fuel F23Q 2/00)

for evaporating and igniting liquid fuel, e.g. in hurricane lanterns

for gaseous fuel, e.g. in welding appliances

actuated by gas-controlling device

Portable igniters

with built-in battery

with built-in generator

with built-in mains transformer

Details

Safety arrangements

Provision for re-ignition

Pilot flame igniters

without interlock with main fuel supply

for upright burners, e.g. gas-cooker burners

for inverted burners, e.g. gas lamps

with interlock with main fuel supply

to determine the sequence of supply of fuel to pilot and main burners

to permit the supply to the main burner in dependence upon existence of pilot flame

using electric means, e.g. by light-sensitive elements
