    • A digital computer system and method for storing and retrieving data contained in a "relational data table" in such a way that individual items of data are readily accessible and the data itself is compressible. The items of data are arranged in the table in a plurality of rows and columns. The items of data in each given column are of the same type (fixed length character, variable length up to a prescribed maximum length, etc.). The items of data are arranged in a particular data format which comprises a plurality of "column descriptor" or "C" records, each of which is associated with one column of the table, followed by a plurality of "data" or "D" records which include the items of data in the table. The D records and C records contain the following information: Each D record includes one or more of the items of data from a particular table row. It is therefore associated with this table row and with at least one table column. Each C record, which is associated with one of the table columns, includes an identification of the associated column, an identification of a D record which includes an item of data in the associated column, and a number defining the absolute displacement of the beginning of the items of data arranged in the respective column with respect to the beginning of the D records associated with that column.
    • 一种用于存储和检索包含在“关系数据表”中的数据的数字计算机系统和方法,使得可以容易地访问各个数据项并且数据本身是可压缩的。 数据项在多个行和列中排列在表中。 每个给定列中的数据项具有相同类型(固定长度字符,可变长度,直到规定的最大长度等)。 数据项被排列成特定的数据格式,其包括多个“列描述符”或“C”记录,每个“列描述符”或“C”记录与表的一列相关联,后跟多个“数据”或“D” 包括表中数据项的记录。 D记录和C记录包含以下信息:每个D记录包括来自特定表行的一个或多个数据项。 因此,它与此表行和至少一个表列相关联。 与表列之一相关联的每个C记录包括关联列的标识,包括关联列中的数据项的D记录的标识,以及定义开头的绝对位移的数 相对于与该列相关联的D记录的开始在相应列中排列的数据项。

    • Apparatus for containing and collecting leaks from the stuffing box of a fluid producing wellhead comprising collection means carried by the wellhead below the stuffing box and encircling the wellhead and at least two separate upstanding hollow shapes of such cross-sectional configuration that when they are brought into abutment with one another the volume enclosed within abutting shapes encircles the wellhead and extends from the liquid collection means to above the stuffing box, said shapes having apertured top edge means which form an opening that encircles the polished rod that reciprocates through the stuffing box, the shapes being hingedly engaged so they can be pivoted toward and away from one another for ease of access to the enclosed stuffing box as desired.
    • 用于容纳和收集来自流体产生井口的填料函的泄漏的装置,包括由填料函下方的井口承载的围绕井口的收集装置和至少两个独立的直立的中空形状,这些中空形状当它们被带入 彼此邻接,封闭在邻接形状内的体积环绕井口并且从液体收集装置延伸到填料函上方,所述形状具有多孔顶边装置,其形成围绕穿过填料函往往的抛光棒的开口, 形状被铰接地接合,使得它们可以彼此枢转并远离彼此,以便于根据需要进入封闭的填料函。
