    • A method for preventing the overcharging of coal into a coke oven system in which preheated coal is transported from a storage container to the coke ovens by means of a substantially enclosed continuous conveyor system filled with inert gas. A portion of inert gas within the enclosed conveyor system is carried along with the coal into the coke oven itself. During filling of the oven, this inert gas is carried up and out of the oven standpipes. When the oven becomes filled, however, the standpipe escape route becomes blocked resulting in a rapid pressure build-up within the system. This rapid pressure build-up is utilized to generate a signal to stop further filling of the oven. The instant method may be employed as a primary regulating system, but is more preferably employed as a back-up to conventional sensor probes used for regulating the level of coal.
    • 一种防止煤进入焦炉系统的方法,其中预热的煤通过填充有惰性气体的基本封闭的连续输送系统从储存容器运输到焦炉。 封闭的输送系统内的一部分惰性气体与煤一起被运送到焦炉本身。 在炉子的填充期间,将这种惰性气体带走并排出烘箱立管。 然而,当烤箱变得充满时,立管溢流路径被堵塞,导致系统内的快速压力积聚。 这种快速的压力积聚被用于产生停止进一步填充烤箱的信号。 本方法可以用作主调节系统,但是更优选地用作用于调节煤水平的常规传感器探针的备份。

    • A system for facilitating commercial transactions, between a plurality of customers and at least one supplier of items over a computer driven network capable of providing communications between the supplier and at least one customer site associated with each customer. Each site includes an associated display and an input device through which the customer can input information into the system. At least one supplier is presented on the display for selection by the customer using the input device. Similarly items from a supplier can be displayed for the customer to observe. Associated with a supplier of such items is an item database including information on presented items. Pricing subsystem receives information from the item database to determine the cost associated with a presented item. In addition a customer information database stores information relating to the customer. Associated with each customer is a customer monitoring object for each customer. The customer monitoring object is created by referencing information, relating to that customer, which had been stored in the customer information database and when the customer selects a supplier. The customer monitoring object is configured to operate by responding to customer enquiries regarding a presented item by retrieving information relating to the item and presenting the information to the customer; receiving a customer's selection of a presented item; receiving customer communications, indicating a desire to receive the item; and passing a communication to initiate the delivery of the item to the customer.
    • 一种用于促进商业交易的系统,在多个客户和至少一个计算机驱动网络上的至少一个物品供应商之间,能够提供供应商和与每个客户相关联的至少一个客户站点之间的通信。 每个站点都包括一个相关的显示器和一个输入设备,客户可以通过该设备将信息输入到系统中。 在显示器上呈现至少一个供应商,供客户使用输入设备选择。 来自供应商的类似项目可以显示给客户观察。 与这样的项目的供应商相关联的是包括关于呈现项目的信息的项目数据库。 定价子系统从项目数据库接收信息以确定与呈现项目相关联的成本。 此外,客户信息数据库存储与客户有关的信息。 与每个客户相关联的是每个客户的客户监控对象。 客户监控对象是通过引用与该客户有关的信息来创建的,这些信息已被存储在客户信息数据库中,以及何时客户选择供应商。 客户监控对象被配置为通过检索与该项目有关的信息并向客户呈现信息来响应客户对所呈现的项目的查询的操作; 接收客户对所呈现的项目的选择; 接收客户通信,表示希望接收该项目; 并通过一个通信来启动该项目的交付给客户。

    • In the handling and charging of pre-heated coal, the coal is transported from a coal storage container to the oven chambers by an enclosed continuous conveyor system. The coke oven chambers are charged individually in a continual manner by transporting a measured amount of coal from the container, sufficient to fill a respective chamber. If coal, due to a malfunction, passes beyond the intended charging hole, it can jam the drive area causing extensive damage. To prevent this, a safety device is provided which includes a sensing device, e.g. a pivotally mounted switch for determining the presence of coal on the conveyor and associated therewith, a time delay system for determining if a particular amount of coal, to which the sensor is responding, is of sufficient volume to cause jamming of the conveyor drive system.
    • 在预热煤的处理和装料中,煤通过封闭的连续输送系统从储煤容器运送到炉室。 通过从容器中输送测量量的煤,足以填充相应的室,连续地对焦炉室进行充电。 如果煤由于故障而超过预期的充电孔,可能会堵塞驱动区域造成广泛的损坏。 为了防止这种情况,提供了一种安全装置,其包括感测装置,例如, 用于确定在输送机上与其相关联的煤的枢转安装的开关,用于确定传感器响应的特定量的煤具有足够体积以导致输送机驱动系统卡住的时间延迟系统。
