Equipment for the reduction of metal oxides with carbonaceous reductants includes a pair of straight moving hearth furnaces each having a charging end and a discharging end. Each furnace has a train of detachable sections to enable each section to be removed at the discharging end of one furnace and attached at the charging end of the other furnace.

An anti-staining additive comprising a higher unsaturated aliphatic acid ester-modified organosilicon compound that is produced by carrying out an addition reaction between (a) a higher unsaturated aliphatic acid ester that contains more than one aliphatically unsaturated bond in each molecule and (b) an organosilicon compound that contains at least 1 silicon-bonded hydrogen atom in each molecule ...

A method is provided for stripping a polymer film from a floor surface, comprising the steps of: (a) applying a concentrated alkaline stripper solution including an alkaline agent and a solvent, to the polymer film; (b) allowing this concentrated alkaline solution to chemically act on the polymer film during a contact time of at least 5 seconds; (c) scrubbing the polymer film with a scrubbing devi...

There is provided a method of directing an internet protocol IP packet to a mobile node. The mobile node has a home address in a home network and is temporarily connectable in a foreign network having a foreign agent. The IP packet has a header portion including the destination address to which the IP packet is to be sent. The method comprises the steps of receiving, in the home network, the IP pa...

A method of insuring the accuracy of transmitted or stored digital data involves the use of a cyclical redundancy check (CRC) code. The method is particularly useful for ensuring the accuracy of frames transmitted between multi-mode vocoders. The method allows a different CRC code to be used for each mode of a transmitting multimode vocoder. A receiving multi-mode vocoder checks the CRC code again...

A digital data communication system is provided for transmitting a high speed differentially encoded data signal between a transmitter and a receiver. On the transmitter side (44), a high speed input data stream (42) is separated into a plurality of lower rate data streams by a demultiplexer (46). Prior to being multiplexed together to form a single high speed data stream, each of the lower rate d...

A process for extracting fragrant, flavoursome or pharmacologically active components from natural materials using non-chlorinated hydrocarbon solvents. The process enables the more volatile components of plant derived materials, which are frequently lost in conventional methods of extraction, to be extracted. This results in the extracted components bearing a greater similarity to, and possessing...

An inventive partitioned closed container comprises a cylindrical main body, a partition provided within said main body in a body therewith along the longitudinal direction thereof and lids for closing openings of the main body. The lids are joined with the main body and the partition by means of frictional agitating joining or laser welding. Thereby, it is possible to realize a good joining condi...

The present invention provides a powdered catalyst material based on aluminium oxide, which contains at least one basic metal oxide and at least one noble metal from the platinum group of the Periodic System of Elements in addition to aluminium oxide.
