Title: Oxygen-reduced aqueous solution of factor viii
Inventor: STERBERG THOMAS
IPC: A61K38/37
Filed: 1994-03-24
Abstract: The present invention relates to a final drug product comprising coagulation factor VIII in an aqueous solution with a reduced concentration of oxygen. In this way, the factor VIII activity can be retained during storage to a surprisingly high degree. The factor VIII  activity can be retained for a prolonged period of time, if the final drug product further comprises an inert gas and/or an antioxidant. The present invention also relates to processes for reducing the oxygen concentration of the aqueous solution, and a method for improving the stability of factor VIII in an aqueous solution by storing the solution under an inert gas atmosphere. By the present invention it is possible to retain at least 50 % of the initial activity of factor VIII after storage for at least 6 months at a temperature of 2 to 10 °C and a pH of the solution of 6.5 to 8.5.

Title: A gas turbine engine combustion chamber
Inventor: TOON IAN JAMES
IPC: F23R3/28
Filed: 1994-05-24
Abstract: A combustion chamber (44) which has a primary combustion zone (52) and a secondary combustion zone (56) is provided with a plurality of secondary fuel and air mixing ducts (88) arranged around the primary combustion zone (44). The secondary fuel and air mixing ducts (88) are defined by a pair of annular walls (92, 90) and by a plurality of walls (94) extending radially between the annular walls (90, 92). Each secondary fuel and air mixing duct (88) has an aperture (104) to direct a fuel and air mixture into the secondary combustion zone (56). The apertures (104) have the same flow area. Each secondary fuel and air mixing duct (88) has one or more fuel injectors (100) to inject fuel into the upstream end of the secondary fuel and air mixing duct (88) where air enters through an inlet (98). This arrangement ensures that the fuel/air ratio emitted from each aperture (104) is within 3.0 % of the mean fuel/air ratio of all the apertures (104) even though the air flow to the secondary fuel and air mixing ducts (88) is non uniform.

Title: Method of separating a solute from other solutes
Inventor: WATKINSON JOANNE LOUISE
IPC: C07C303/22
Filed: 1995-05-04
Abstract: A method of separating a solute from one or more other solutes in a solution comprises insolubilising the solute to be separated from the solution, and passing the insolubilised solute and the remaining solution in contact with a membrane. The insoluble particles cannot pass through the membrane filter but the solute(s) remaining in solution pass through the membrane filter and are thus separated from the insoluble particles. This method is particularly suitable in the manufacture of N-acyl taurate derivatives, and especially in the of sodium N-cocoyl, N-methyl taurate.

Title: Active yoke hidden hinge digital micromirror device
Inventor: HORNBECK LARRY J
IPC: H04N5/74
Filed: 1996-04-09
Abstract: A spatial light modulator of the DMD type having increased performance parameters. A pixel mirror is supported by a yoke whereby electrostatic attraction forces are generated between several structures. First, between the elevated mirror and an elevated address electrode. Second, between the yoke and an underlying address electrode. The pixel achieves high address torque, high latching torques, high reset forces, and greater address margins over previous generation devices. The proximity of the yoke over the substrate address electrodes realizes large attraction forces whereby the pixel is less susceptible to address upset, requires lower reset voltages and provides higher switching speeds.

IPC: H04N21/47
Filed: 1994-10-13
Abstract: A system for allowing software publishers to control which video stan-dard(s) can be recovered from an optical disk (23) containing video source ma-terial. The disk may be digitally encoded so that any of NTSC, PAL and other video signal standards can be generated upon proper decoding. But the disk also includes a code which can lock out one or more standards. Players (21) for such disks may be capable of generating video signals according to all popular stan-dards, in which case the user selects a desired standard. However, the player will generate a video signal of the selected standard only if there is an appropriateauthorization code on the disk. The system allows manufacture of "universal" players without necessarily impacting the contractual and marketing plans of mo-tion picture companies, for example, which release films in different territories at different times. The control technique can be extended to lock out specific territories. Each player has a built-in territory code. The player will play a disk only if the disk contains an authorization code for the player's specific territory.
