The filing of such affidavit shall operate as an application to set aside the bankruptcy notice, and thereupon the Registrar shall fix a day for hearing such application, and not less than three days before the day so fixed shall give notice thereof both to the debtor and the creditor at the addresses given by them under rule 40. If the application cannot be heard until after the expiration of the time specified in the bankruptcy notice as the day on which the act of bankruptcy will be complete, the Court shall extend the time, and no act of bankruptcy shall be deemed to have been committed under the notice until the application has been heard and determined.
