Which of the following financial instruments is a specific example of a bill of exchange?

A company grants an 'Assignment of Book Debts' to Bank A to secure a working capital limit. Simultaneously, it creates a 'Floating Charge' on all current assets (including book debts) in favour of Bank B. Both charges are registered with the Registrar of Companies (ROC). If the company goes into liquidation, which bank has the priority over the receivables?

A manufacturing firm imports raw materials and secures a loan by providing a 'Trust Receipt' to the bank. The bank allows the firm to take possession of the goods (originally covered by a Bill of Lading held by the bank) to process and sell them. The firm subsequently sells the goods but uses the proceeds to pay off other suppliers instead of the bank. What is the legal status of the bank's charge on these goods, and what action can the bank take?
