Abstract: A method comprising: providing an alkyl halide stream; contacting at least some of the alkyl halides with a coupling catalyst to form a product stream comprising higher hydrocarbons and hydrogen halide; contacting the product stream with a solid reactant to remove at least a portion of the hydrogen halide from the product stream; and reacting the solid reactant with a source of oxygen to generate a corresponding halogen.

Abstract: A method and apparatus for deferring media writes for emulation drives are provided. By deferring media writes using non-volatile storage, the performance penalty associated with RMW operations may be minimized. Deferring writes may allow the RMW operations to be done while the disk drive is idle. Further, deferring writes may also allow data blocks to be accumulated over time, allowing a full (4K) disk drive block size to be written with a simple write operation, thus making a RMW unnecessary.

Abstract: In a centrally controlled resource arbitration system, each of the units concurrently requesting access sends its identity code and the binary complement thereof to a central arbitration processor. The identity codes are logically combined into a first word, and the binary complements are logically combined into a second word. A subset identifier of the requesting units is then formed by combining corresponding bits of the first and second words. Unresolved values in the subset identifier are iteratively removed to eliminate a subset of the requesting units. When all but one of the requesting units have been eliminated, access to the resource is given to the remaining unit.

Abstract: Disclosed is a multiple port memory apparatus responsive to r+w addresses within an instruction cycle for supplying data read from the r read addresses and for writing data received to the w write addresses. The memory apparatus comprises r groups of w+1 memory banks, responsive to the r read addresses and the w write addresses, for supplying for each of the r read addresses data read from one of the w+1 banks in one of the r groups and for writing data received to each of the w write addresses in the other of the w+1 banks in the r groups. A pointer for controlling the r groups of w+1 memory banks directs the read and write accesses to the memory banks so that one of the w+1 banks obtaining valid data is read in response to a read address and so that data is written to the other banks in each cycle.The pointer directs memory accessing to prevent conflicts.

Abstract: Pd/Sn seeds for use in electroless copper plating are accelerated by treating them with an alkali metal hydroxide at a pH of about 11.3 and at a temperature above 50.degree. C.
