Brays Elta was a kind of acetylene lamp and torches
Translated text: eaks conjugés Bray "Elta"
Conjugated beaks Bray "Luta"
The beaks, often made in brass, or in recalcitrant matter as the stéatite to withstand the strong temperatures of combustion of the acetylene, have debits set up theoretical calculated in liters of gas an hour. They can be simple or conjugated (to double gone out), to simple release or to air call. The conjugated models project two flows of gas the one against the increasing other thus considerably the size of the flame. In the models to air call, the acetylene while escaping entraine of the air, which improves the combustion and reduced the encrassement of the burner. The models to simple flame of 14 or 21 liters are the more running.
