摘要： A system and method for controlling fluid pressure downstream a main valve includes associating a variable orifice with the main valve such that the variable orifice opens as the main valve is opened and closes as the main valve is closed. A fluid stream taken from a fluid inlet of the main valve is passed to an inlet of the variable orifice. A fixed orifice is in fluid communication with an outlet of the variable orifice. A pressure differential between the inlet and outlet of a fixed orifice is detected by a control pilot device, which hydraulically opens or closes the main valve in response to the detected fixed orifice pressure differential between low pressure and high pressure set points.

摘要： A system for hydraulically managing fluid pressure between selected set points includes a pilot control system operably coupled to a main valve. The pilot control system includes at least one fluid conduit, a variable orifice assembly, and a control pilot valve apparatus. Fluid is passed through a fixed orifice and into a first chamber of the control pilot valve apparatus. Fluid is passed through the variable orifice of the variable orifice assembly and into a second chamber of the control pilot valve apparatus. The main valve is hydraulically opened or closed in response to a pressure differential between the first and second chambers of the control pilot valve apparatus so as to manage fluid pressure downstream of the main valve between the selected upper and lower set points.

摘要： A drilling or service rig includes a worm drive disposed within and rotatably supported within a mast having one open side. The worm drive defines a helical groove, and a collar is disposed on the worm drive and engages the helical groove. Rotation of the worm drive causes movement of the collar upwards or downwards along the worm drive. The collar may support a block and top drive assembly.

摘要： A method and apparatus is provided for recording at least one program received over a broadband communications system. The method begins by accessing a database that includes program information that describes with program attributes a plurality of programs available over the broadband communications system. User-defined criteria are received that identify preferred program attributes. The database is sorted through to identify at least one preferred program having program attributes that include the preferred program attributes. From information in the database a first scheduled time at which the preferred program is to be received is identified. The first scheduled time is compared to another scheduled time of another program to be recorded. If the first scheduled time and the other scheduled time overlap in whole or in part, thereby giving rise to a scheduling conflict, the method continues by sorting through the database to identify a second scheduled time at which either the preferred program or the other program is available. Recording is then scheduled at the second scheduled time of either the preferred program or the other program that is available at the second scheduled time. Recording is next scheduled of a remaining one of the preferred program or the other program at the first scheduled time or the other scheduled time, respectively.
摘要翻译：提供了一种用于记录通过宽带通信系统接收的至少一个节目的方法和装置。该方法开始于访问数据库，该数据库包括通过宽带通信系统可用的多个程序来描述节目属性的节目信息。收到用于标识首选程序属性的用户定义标准。数据库被排序以识别至少一个具有包括优选程序属性的程序属性的优选程序。从数据库中的信息确定要接收优选程序的第一预定时间。将第一个预定时间与要记录的另一个节目的另一个预定时间进行比较。如果第一预定时间和其他预定时间全部或部分重叠，从而引起调度冲突，则该方法通过数据库排序来识别第二预定时间，优选程序或其他程序是可用。然后在第二预定时间的第二预定时间安排记录，该优先方案或在第二预定时间可用的其他节目。下一次计划在第一预定时间或其他预定时间内分配剩余的优选节目或其他节目的记录。
