A three compartment electrolytic cell is provided having (1) a catholyte compartment containing a cathode assembly comprising a cathode and anion exchange membrane, (2) an anolyte compartment containing an anode assembly comprising an anode and a cation exchange membrane, and (3) an intermediate compartment partitioned from the catholyte and anolyte compartments by the anion and cation exchange membranes respectively. An aqueous solution of .alpha.-halohydrin is charged to the catholyte compartment, while hydrogen halide solutions are charged to the intermediate and anolyte compartments. Direct current is passed through the electrolytic cell and an aqueous solution comprising epoxide is removed from the catholyte compartment.

    摘要: Method and system aspects control access through a synchronization primitive to a peripheral device in a processing system. A processing system in accordance with the present invention includes at least one central processing unit (CPU), and at least one peripheral device coupled to the at least one CPU, where the at least one peripheral device includes a synchronization primitive for controlling acquisition by at least one thread of execution from the at least one CPU. In a system aspect for controlling access, the system includes a circuit for sending a first signal from a component of the processing system to a synchronization primitive within the peripheral device to determine a state of the synchronization primitive, and acquiring control of the peripheral device when the synchronization primitive is in a released state. In a method for gaining control of a peripheral device in a processing system, the method includes sending a first signal from a component of the processing system to a semaphore register within the peripheral device to determine a bit pattern in the semaphore register, and acquiring control of the peripheral device when the semaphore register stores a first bit pattern.
