Comm. NT: 37. Abhinīhāra—“conveying”: not in this sense in PED.
Catudhātuvavatthānabhāvanāvaṇṇanā
‘Conveying’ is acting as cause for the successive arising at adjacent locations (desantaruppatti) of the conglomeration of elements (bhūta-saṅghāta)
Elsewhere Vism-mhṭ (p. 359) says of the air element:
Catudhātuvavatthānabhāvanāvaṇṇanā
“‘It blows’ (§87): it is stirred; the meaning is that the conglomeration of elements is made to move (go) by its action as cause for successive arising at adjacent locations (points),
and
Catudhātuvavatthānabhāvanāvaṇṇanā
Propelling (samabbhāhana) is the act of causing the successive arising at adjacent locations of material groups (rūpa-kalāpa)
