摘要： A lock system which prevents the mixing of different kinds of oil at a gasoline tank comprises: locks for different kinds of oils provided on each of couplings constituting oil filler ports of underground tanks of the gasoline stand and each of tank base valves of a tank truck, and keys separately provided for unlocking the locks for the different kinds of oil, wherein only the lock on the couplings of the oil filler ports which accepts a selected key which unlocks the corresponding tank base valve of the tank truck can be unlocked. When one of the tank base valves is opened and an oil filler hose is connected to the oil filler port of one of the underground tanks, only the oil filler port of the underground tank containing the same kind of oil as that in the corresponding tank of the tank truck can be opened, thereby ensuring that the same kind of oil is reliably poured into the underground tank from the tank truck. The keys are stored in a key-storing device which holds the keys separately for the different kinds of oil, and is constructed such that only one key for one kind of oil can be removed at a time. It is thereby possible to provide a lock system preventing the mixing of different kinds of oil at a gasoline stand, which can reliably prevent the mixing of different kinds of oil with simple devices and members.
摘要翻译：防止在汽油罐中混合不同种类的油的锁定系统包括：在构成汽油架的地下罐的加油口的每个联接器上设置的各种油的锁和罐车的每个罐底阀，以及单独设置的用于解锁用于不同种类的油的锁的键，其中仅可以解锁用于接收选择的钥匙的加油口的联接器上的锁定，该钥匙解锁罐车的相应的罐底阀。当其中一个罐底阀打开并且一个地下油箱的加油口连接有加油软管时，只有地下油箱的加油口含有与相应油罐相同种类的油罐车可以打开，从而确保同一种油从油罐车可靠地倒入地下油箱。钥匙存储在密钥存储装置中，该密钥存储装置分别保存用于不同种类的油的密钥，并且被构造成使得一次只能去除一种油的一个密钥。从而可以提供一种防止汽油架上的不同种类的油混合的锁定系统，能够以简单的装置和构件可靠地防止不同种类的油的混合。

摘要： An overfill preventing device in an underground liquid storage tank is characterized in that a window for extending outwardly or accommodating a float is provided on a peripheral wall of a cylindrical sleeve, that an upper end of the float is pivotally attached to the cylindrical sleeve at a position above the window, and that a closure valve is mounted on the upper end of the float to open or close the cylindrical sleeve at a position above the window. Since the window for extending the float outwardly or accommodating the float inwardly is formed inside the cylindrical sleeve, the float can be firmly stored. When the float is extended outwardly from the cylindrical sleeve after installing the device of the present invention, the window is closed by a lid and the lid forms a part of the cylindrical sleeve so that construction of the space within the cylindrical sleeve necessary for liquid flow is minimized, whereby liquid is smoothly supplied into the underground liquid storage tank.

摘要： In case where a cylindrical gasoline tank embedded in the underground of a gasoline station is of the horizontal type, a liquid level sensor for sensing the liquid level of the gasoline is disposed in the tank, the liquid level in the tank as sensed by the sensor is converted into an electric signal, the electric signal is converted into a signal expressive of the quantity of the gasoline received in the tank by utilizing a segmental function, and this signal is used to indicate the received quantity of the gasoline with electric-light numerals.
