    • A secured lien monitoring system is provided that includes a tag affixed to property or documents, the tag communicating with a reader. The tag includes a memory for storing tag data, a transmitter and a receiver. The tag transmits and receives tag data to a reader in response to an interrogation request, or automatically. The tag data includes an identification number used to identify the tag associated with a particular asset and secured lien. The identification number in the tag may be an Electronic Product Code identification number assigned to a particular product or document. Information about the object to which the tag is attached may be described with a Product Markup Language. The lien monitoring system includes extending the Product Markup Language to manage Lien attributes used to monitor liens for specific collateral assigned and identified by an EPC and debtors. The EPC tag number may be used to point to secured lien information, including date filed, lien amount, lien filing number, recording fees, debtor information, creditor information, filing location, expiration date and other related information available locally or on a network.
    • 提供了一种安全的留置权监控系统,其包括贴在财产或文件上的标签,标签与读者通信。 标签包括用于存储标签数据的存储器,发送器和接收器。 该标签响应询问请求或自动地向标签读取器发送和接收标签数据。 标签数据包括用于识别与特定资产和安全留置权相关联的标签的标识号。 标签中的标识号可以是分配给特定产品或文档的电子产品代码标识号。 有关附加标签的对象的信息可以用产品标记语言来描述。 留置权监控系统包括扩展产品标记语言以管理用于监控由EPC和债务人分配和确定的特定抵押品的留置权的连接属性。 EPC标签号可用于指向本地或网络上可用的有担保留置权信息,包括日期提交,留置权,留置申请号,记录费用,债务人信息,债权人信息,归档位置,到期日期和其他相关信息。

    • Oil is recovered from a borehole using a pump having limited high temperature breakdown resistance. The pump is located in a borehole having a cooling zone, in which the temperature of the well fluid is reduced to, or below, the temperature at which the temperature breakdown resistance of the pump is commercially acceptable. In one embodiment, the pump is a positive displacement pump which is mechanically driven from the well head location, such as through a rotating rod. The cooling zone is provided by positioning and controlling the pump to maintain a sufficiently low pressure at the pump intake to cause a portion of the liquid well fluid to vaporize prior to entry of the liquid into the pump, creating bubbles which pass upwardly in the wellbore in a zone passing the pump. The evolution of the vapor cools the well fluid to the acceptable temperature.
    • 使用具有有限的耐高温击穿电阻的泵从井眼回收油。 泵位于具有冷却区的钻孔中,其中井流体的温度降低到或低于泵的耐温性破坏性在商业上可接受的温度。 在一个实施例中,泵是从井口位置例如通过旋转杆机械驱动的容积式泵。 通过定位和控制泵来提供冷却区域,以在泵入口处保持足够低的压力,以使液体的一部分液体在液体进入泵之前蒸发,产生在井眼中向上通过的气泡 在通过泵的区域。 蒸气的演化使井液冷却至可接受的温度。
