The apparatus may include an injection section, a combustion section, and an evaporation section.

The current injection section CIS is electrically decoupled from the at least one other section OS1 when the current injection section CIS and the at least one other section OS1 are adjacent to each other.

The delivery section (46; 81; 104) may be coupled with the injection section (50; 82) at an inlet disposed between opposite ends (53, 53) of the injection section (50; 82).

A polarising material (1.9) is provided between the optical waveguide and the injection device at the injection section.

The tool 1 comprises a current injection section CIS and a current return section CRS.

The current injection section CIS is electrically decoupled from the current return section CRS.

The injection section may include a housing, injector elements, and injector plate.

A particle suspension furnace (10) having an upper injector section (11), an intermediate combustion section (12) and a lower separation section (13).

The passage body is composed of a water-gathering section (1), an accelerating section (2) and an injecting section (3) from above to below.

In the second condition, the first side faces the blowing section and the second side faces the injection section.

In the first condition, the first side faces the injection section and the second side faces the blowing section.

A fluid lumen (56) of the injection section (50; 82) may have a larger cross-sectional area than a fluid lumen (45) of the delivery section (46; 81; 104).

A transfer section (38) between the injection section and the blowing section is rotatable by 180° about a second axis transverse to the first direction between a first condition and a second condition.

A molding apparatus has an injection section for injecting material for forming parisons.

The lid (3) has an injection section (10) that opens into a gap formed between the curved sections of the electrode body (2).
