Title: Method and apparatus for multicast transmission of packet data in a mobile communication system
Inventor: LEE SUNG-WON
IPC: H04L12/70
Filed: 2003-06-02
Abstract: An apparatus and method for multicast transmission of packet data in a mobile communication system. To multicast packet data to a group of MSs, a BS divides a plurality of MSs within its cell area into a plurality of multicast groups.     Here, the MSs of each multicast group are to receive the same data. The BS assigns a MMAC index to each multicast group. Upon receipt of a multicast traffic channel request message from an MS, the BS transmits to the MS a traffic channel assignment message with the MMAC index of a multicast group to which the MS belongs and transmits forward packet data to the MS on a traffic channel corresponding to the MMAC index.

Patent CA-2444143-A1 (CA)
Inventor: SENIOR GEOFFREY DAVID
IPC: B03D1/08
Filed: 2002-04-11
Abstract: The present invention relates to a gravity/flotation circuit where a mineral stream, such as a flotation rougher or cleaner concentrate, undergoes a two stage size separation wherein: i) the screen of the first stage provides a coarse stream of particles greater than 110 microns and a fines stream of particles less than 110 microns; and ii) the fines stream of less than 110 microns is subjected to the second stage separation whereupon a cyclone provides an ultrafine/slimes stream of p80 less than about 25 microns and a middlings stream of p80 greater than around 25 microns. The middlings stream is subjected to flotation to recover nickel sulphide which is sent to final concentrate, and reject or depress magnesia which undergoes gravity separati on to concentrate the MgO. It has been discovered that a large proportion of th e MgO minerals in the concentrate are contained in the 30 to 100 micron size fraction and that they are well liberated making physical separation possibl e. Furthermore, the nickel sulphide minerals and magnesia minerals have a significantly different specific gravity which can be exploited using gravit y separation equipment to achieve magnesia rejection.
