20130266029 | NETWORK NODE FOR AN OPTICAL TRANSPORT NETWORK - A network node for an optical transport network is disclosed, which has a signal input for receiving a multiplexed transport signal carrying a number of n timeslots of a fixed size data capacity, a demultiplexer for demultiplexing the received signal into a number of m>1 sub-signals, each sub-signal carrying a fraction of n/m of said timeslots, one or more space switch modules for configurably switching said sub-signals, and a multiplexer receiving sub-signals from said one or more space switch modules; for multiplexing timeslots from said sub-signals into an outgoing multiplexed transport signal carrying n of said timeslots. The multiplexer is connected to the one or more switch modules over a number of l>m interconnections and receives from said one or more switch modules up to l sub-signals. Moreover, the multiplexer can be configured to select the n timeslots for the outgoing multiplexed transport signal from the up to l sub-signals. | 10-10-2013 |

20110182787 | METHOD FOR PRODUCING TITANIUM TETRACHLORIDE BY USING LOW-GRADE TITANIUM MATERIAL - The invention provides a method for producing titanium tetrachloride by using a low grade titanium material, and belongs to the chemical field. The technical problem to be solved is to provide a method for producing titanium tetrachloride by using a low grade titanium material capable of continuous industrialized production. The method is characterized in that the low grade titanium material containing a certain proportion of titanium carbide is caused to directly react with chlorine at 600-700° to produce the titanium tetrachloride. Long-time continuous and stable operation can be realized by using the process parameters of the method, and chlorination rate of the titanium carbide in the titanium material reaches above 90%, so that the titanium material can be better used for producing the titanium tetrachloride. | 07-28-2011 |
