摘要： Aluminum phosphate having reduced fines is produced by gelling said aluminum phosphate in the presence of an acrylamide polymer. The resulting support is of primary utility as a base for a chromium olefin polymerization catalyst but is also suitable as a support for titanium catalysts such as TiCl.sub.3, TiCl.sub.4 /MgCl.sub.2 and other conventional catalysts typically associated with polymerization of propylene.

摘要： Water-soluble polymers comprising N-vinyl amide such as an N-vinyl lactam are found to be useful in processes wherein the polymer is introduced into a subterranean wellbore. Polymers useful in the recovery of natural resources are prepared by polymerizing an N-vinyl lactam by free radical initiation with polymerization conducted in an aqueous solution polymerization medium preferably containing a mixture of dissolved electrolytes, or in a polymerization medium consisting essentially of a tertiary alkanol. Copolymers of such N-vinyl lactams with unsaturated amides and terpolymers prepared by polymerizing an N-vinyl lactam and an unsaturated amide with a selected termonomer compound are also useful when prepared by these methods. The invention also broadly encompasses utilizing a water-soluble polymer comprising at least one of a hydrophilic vinyl-containing sulfonate, phosphonate or ester and/or hydrophilic N-vinyl lactam for applications under hostile conditions.

摘要： A hardware accelerator includes hardware support for a combinational only cycle and a latch only cycle in a simulation model with a single partition of latches and combinational logic. Preferred embodiments use a special 4-input 1-output function unit in the hardware accelerator in place of the normal latch function that write back the old latch value for combinational only cycles. Other embodiments include hardware support for separate array write disables for arrays and transparent latches depending on whether the cycle is a combinational only cycle and a latch only cycle. A conditional array write disable dependent on the occurrence of a hardware breakpoint is also included that supports switching from a latch plus combinational cycle to a latch only cycle, to give control to the user before evaluating the combinational logic if a breakpoint occurs on a latch.
摘要翻译：硬件加速器包括仅组合的周期的硬件支持，并且锁存器仅在具有锁存器和组合逻辑的单个分区的仿真模型中循环。优选实施例在硬件加速器中使用特殊的4输入1输出功能单元来代替正常的锁存功能，该功能将仅存储组合的周期的旧锁存值回写。其他实施例包括针对阵列和透明锁存器的单独阵列写禁止的硬件支持，取决于该周期是仅组合周期和仅锁存周期。还包括依赖于硬件断点的发生的条件阵列写禁用，其支持从锁存器加组合周期切换到仅锁存周期，以在对锁存器发生断点时评估组合逻辑之前给予用户控制。
