Title: Flow-type pre-reduction apparatus of powder iron ore and pre-reducing method with the same
Inventor: CHOI NAK JUN
IPC: C21B13/06
Filed: 1998-12-09
Abstract: PURPOSE: A pre-reducing method of powder iron ore is provided to improve reduction and gas-using rate by pre-reducing powder iron ore depending on particle size and to minimize the amount of dispersed powder iron ore. CONSTITUTION: Corpuscular iron ore is dispersed together with exhaust gas, and middle/large iron ore is introduced into a first gas feed pipe(126) from a first flow layer path(110). After that, the middle/large iron ore is reduced primarily as forming a vapor flow layer with reduction gas passing a first gas dispersing plate(112). The middle/large iron ore is charged into the intermediate portion of a second flow layer path(120) and reduced secondarily. The corpuscular iron ore is dispersed together with exhaust gas from the second flow layer path. The corpuscular iron ore is separates from gas in first and second cyclones(114,124) and charged into a third flow layer path(130). The corpuscular iron ore is secondarily reduced, separated from gas and circulates in the third path. The reduction iron of the second/third paths is finally discharged through second and third discharge pipes(121,131) respectively.

Title: Therapeutic applications of t-bam (cd40l) technology to treat diseases involving smooth muscle cells
Inventor: THOMAS DAVID
IPC: A61K39/395
Filed: 1997-07-03
Abstract: PURPOSE: Activation by CD40 ligand (CD40L) of smooth muscle cells bearing CD40 on the surface of the cells is inhibited in vivo and ex vivo by contacting the cells with an agent capable of inhibiting interaction between CD40L and CD40 on the cells. In vivo inhibition of CD40-bearing smooth muscle cells is used to treat smooth muscle cell-dependent diseases. CONSTITUTION: Provided is a method of inhibiting activation by CD40 ligand of smooth muscle cells bearing CD40 on the cell surface, comprising contacting the cells with an agent capable of inhibiting interaction between CD40 ligand and CD40 on the cells, the agent being present in an amount effective to inhibit activation of the cells. In one embodiment of this invention the agent is capable of inhibiting any interaction between CD40 ligand and CD40. "Interaction between CD40 ligand and CD40 on the cells" refers to one or more aspects, functional or structural, of a CD40-CD40 ligand interrelationship. Therefore, in one embodiment, an agent which inhibits interaction may competitively bind to CD40 ligand in such a way to block or diminish the binding of CD40 ligand to cellular CD40. In another embodiment an agent which inhibits interaction may associate with CD40 or CD40 ligand in a manner which does not inhibit binding of CD40 ligand to cellular CD40, but which influences the cellular response to the CD40 ligation, such as by altering the turnover rate of the cellular CD40 or the CD40-agent complex, by altering binding kinetics of CD40 with CD40 ligand, or by altering the rate or extent of cellular activation in response to CD40 ligation.
