摘要： An improved register allocator, an improved instruction scheduler, an instruction combiner, and an improved loop unroller is provided to the code generator of a compiler of a computer system. Both the improved instruction scheduler and the improved loop unroller support a "preliminary" and a "final" mode of operation. Upon invocation, the improved register allocator determines and prioritizes regions of the program being compiled. Next, the improved register allocator, in cooperation with the improved instruction scheduler, the instruction combiner, and the improved loop unroller, determines the optimal partitioning for global and local registers for each region. Then, the improved register allocator allocates registers to each region based on the determined number of global registers for the region. After allocating registers for each region, the improved register allocator merges the regions together. The improved loop unroller and the improved instruction scheduler are then invoked successively in "final" mode to unroll the various loops and schedule the instructions being generated.
摘要翻译：将改进的寄存器分配器，改进的指令调度器，指令组合器和改进的循环未布告器提供给计算机系统的编译器的代码生成器。改进的指令调度器和改进的循环读取器都支持“初步”和“最终”操作模式。在调用时，改进的寄存器分配器确定正在编译的程序的区域并对其进行优先级排序。接下来，改进的寄存器分配器与改进的指令调度器，指令组合器和改进的循环unroller协作，确定每个区域的全局和本地寄存器的最佳分区。然后，改进的寄存器分配器基于确定的该区域的全局寄存器的数量向每个区域分配寄存器。在为每个区域分配寄存器之后，改进的寄存器分配器将区域合并在一起。然后，以“最终”模式连续地调用改进的循环单元和改进的指令调度器来展开各种循环并调度所生成的指令。

摘要： A perforating-gun spacer used to position a plurality of guns to perforate a multizone reservoir is formed of a plurality of telescoping sections which are held in an extended position by tapered pins. A slidable piston maintains the pins in engaged position. When the perforating guns are fired, the resultant pressure pulse in the wellbore fluid moves the piston upwardly out of engagement with the restraining pins which then disengage permitting the telescoping sections to collapse when the expended tool is dropped into the bottom of the wellbore. This avoids partial or complte blockage of the lowermost production zone by the upper portion of the perforating gun string.
摘要翻译：用于定位多个枪以穿孔多区域储存器的穿孔枪间隔件由多个伸缩部分形成，多个伸缩部分通过锥形销保持在延伸位置。可滑动的活塞将销保持在接合位置。当射孔枪被射击时，井筒流体中产生的压力脉冲将活塞向上移动，与限制销接合，然后使其脱开，当膨胀的工具落入井眼的底部时，伸缩部分会塌缩。这避免了由射孔枪串的上部部分或者自发地阻塞最下面的生产区。

摘要： The present invention comprises a vehicle body assembly, 10, comprised of a series of welded together aluminum, stainless base or galvanealed steel panels 12, in interfacing engagement with companion thermo-plastic or thermo-set plastic covering panels, 12, adapted to be pre-colored and resistant to heat, moisture and the environment. The base and covering panel are interposed in facing engagement through the use of a flange, 13, and formed channel, 14, and further secured together through the use of silicon, 19, within the channel and various portions of vehicle trim, 16, of metallic, chrome or rubber material. The use of the covering panel produces a method for assembling the vehicles requiring the base panels to be precisely configured and fitted without painting or previously required disassembly. The pre-colored covering panels are merely inserted into the companion base panel thereby forming a vehicle body of a specific configuration easy to assemble and repair.

摘要： Ball sealers for flowing into casing perforation holes in a wellbore to selectively seal off those perforations receiving a disproportionately large amount of well treatment fluid being injected through the perforations. The ball sealers (22) are comprised of a spherical outer deformable shell (42) defining a central core portion filled with nondeformable particulate matter (46) which is sized small enough to flow with the shape of the deformable outer shell (42) and large enough so that as it consolidates under the force of fluid flow pressure, it will cause the outer shell to bridge over the perforation opening (18) when the force of fluid flowing into the casing (12) pushes the ball sealer (22) against and into the perforation opening (18). The particles (46) are also arranged so that when fluid flow is stopped into the casing and the fluid flow force is no longer applied to the ball seals, the particulate matter (46) will become unconsolidated to relax the bridge and permit the entrapped energy in the deformed outer shell (42) to expel the ball from the perforation opening.
