Abstract: A method for detection of a bubble in a liquid which is placed in a measuring chamber and is in contact with a sensor for measuring the partial pressure of a particular gas in a liquid is provided. The method includes performing a first measurement of the partial pressure of the particular gas in the liquid at a first pressure in the measuring chamber. Next, the pressure in the measuring chamber is changed to a second pressure. A second measurement of the partial pressure of the gas in the liquid at the second pressure in the measuring chamber is performed. An expected result of the second measurement based on the first measurement and assuming that no bubbles are present in the measuring chamber during any of the measurements is provided. The actual result of the second measurement is compared with the expected result and a conclusion is drawn on the presence of a gas bubble in the liquid based on the comparison. An apparatus for measuring the content of a particular gas in a liquid is also provided.

Abstract: A locking device (10) is serving for, with a lock (18), locking an already closed door (4) which is mounted with hinges (6) on a frame (5) in a gable (3) of a container (1). The door is held in the closed position by a turnable locking bar (7) which, at least at one end, has a projection for, by turning the bar, engaging it with a holder on the frame. The locking device (10) furthermore comprises a lock hole (25) running through the locking bar (7), the lock hole (25) assumes, in the closed position, a direction mainly parallel to the door plane; a house (11) with a channel (12) attached to the door, the channel (12) encloses the locking bar (7), and a bolt guide (22) which is in alignment with the lock hole (25) in the closed position; and a sliding bolt (23) for sliding through the bolt guide (22) and the lock hole (25) and locking the locking device (10) with a lock (37) which engage with tumblers (27) in the lock (18). A combination lock can advantageously be used as lock.
