I think I remember seeing the phrase "allow to cool" quite often... Also, it looks like there are other infinitives that can follow immediately after 'allow'. For example: "to allow to proceed at full speed".
The construct <to allow + infinitive with 'to'> looks unusual to me because the English dictionaries/grammar books I have only mention the following constructs:
(1) to allow something (2) to allow somebody to do smth (3) to allow + ing-form
If could could help me to "hitch" the suspect allow to cool/proceed, etc. to the well-established (1),(2), (3)?
