    • A female-molded double-walled underground storage tank is provided with an annulus of reduced thickness, defined by a plastic film. The film separates the inner and outer walls of the tank, providing an annulus which can be monitored to monitor the tank for failure of either the inner or the outer tank, before contamination of the exterior environment. The tank is formed of fiberglass reinforced plastic, the inner and outer walls thereof being tied together by fiberglass reinforced plastic which holds the annular film in place. The domes of the outer and inner shell are separated due to a layer of wax and alcohol applied to the inner surface of the dome of the exterior tank prior to formation of the interior tank. The spaces between the flats of the two tanks, the domes of the two tanks, and the interior of the ribs of the exterior tank are placed in fluid communication by gutters running along the length of the tank.
    • 一个阴模双层地下储罐设有厚度较小的环,由塑料薄膜所限定。 该膜将罐的内壁和外壁分隔开,提供一个环形空间,在环境污染之前,可以对其进行监控,以监测罐体是否存在内罐或外罐的故障。 该罐由玻璃纤维增​​强塑料制成,其内壁和外壁通过将环形薄膜保持在适当位置的玻璃纤维增​​强塑料连接在一起。 外壳和内壳的圆顶由于在形成内部罐之前施加到外部罐的圆顶的内表面上的蜡和醇层分离。 两个坦克的平面之间的空间,两个坦克的圆顶和外部坦克的肋的内部被放置成沿着槽的长度流动的沟槽流体连通。

    • The disclosure describes an electronic mailbox system in which a plurality of like data terminals are provided coupled to a common message carrying facility such as a telephone line wherein any terminal is capable at any selected time of being designated a controlling terminal; and further, wherein any terminal may either transmit or receive messages from any other terminal in the system. The system of the present disclosure is characterized by its ability to maintain effective communication among the terminals despite the occasional or intermittent linking of the terminals into the system. Thus, if a terminal is destined to receive a message but is not on-line or for any other reason does not receive the transmitted message, the system will continue to present the message from time to time until it is received by the destined terminal.
    • 本公开描述了一种电子邮箱系统,其中提供了多个相似的数据终端,其耦合到诸如电话线的公共消息传送设施,其中任何终端在任何选定的时间被指定为控制终端; 并且此外,其中任何终端可以从系统中的任何其他终端发送或接收消息。 本公开的系统的特征在于,尽管终端偶尔地或间歇地连接到系统中,但是能够在终端之间保持有效的通信。 因此,如果终端注定要接收消息但不在线,或者由于任何其他原因不接收所发送的消息,则系统将不时地显示消息,直到由目的终端接收到。
