IPC: C07C329/00
Abstract: 949,042. Isotopic enrichment of carbon disulphide. VAKUTRONIK VEB. March 14, 1960, No. 8992/60. Heading C1A. [Also in Division C2] Carbon disulphide or an alkyl xanthate is enriched in a carbon and/or sulphur isotope by effecting isotopic exchange between countercurrent flows thereof. The CS 2  may be vapour, or liquid, or in solution in a non-inflammable, water-immiscible solvent, e.g. carbon tetrachloride. Preferably CS 2  vapour may be passed through an aqueous alkyl xanthate solution in a column at elevated temperature or reduced pressure. Heavy C and S isotopes are stated to be concentrated in the xanthate and light isotopes in the CS 2 . The enrichment is increased by converting CS 2  to xanthate, which is returned to the column. The enriched products may be burnt to CO 2  and SO 2  which are reacted to carbonates or sulphites.

Title: Bus connection set up and tear down
Inventor: BOWATER RONALD JOHN
IPC: H04Q11/04
Filed: 1997-05-06
Abstract: A bus connection controller in a voice processing is for managing the connection of a timeslot on a time-division multiplex (TDM) bus to a port on an adapter. The voice processing system includes basic time-division multiplex (TDM) connection management to enable the coordination of connections between resources such as channels on line cards (SPacks or VPacks), and channels on digital signal processor (DSPs) cards that provide, amongst others things, voice recognition, text-to-speech, fax capabilities and so on. Problems are encountered when a telephone call in a voice processing system ends suddenly because one of the callers hangs up. If the telephony channel has connections with other channels or resources via a TDM bus, callers may hear spurious data. To address this problem each call is associated with its corresponding connection on the TDM bus and each connection is associated with its connection details including the adapters and ports involved in connecting the calls. When one of the calls ends all the relevant ports involved with the connection are immediately disconnected.
