Patent CH-365096-A (CH)
Inventor: MARVIN J UDY
IPC: C01F7/743
Filed: 1956-12-17
Abstract: Iron, titanium and aluminium values are recovered from materials comprising their oxides, together with silica such as ilmenite in admixture with silica and alumina, high iron bauxite ores, and the red mud residues resulting from the alkaline extraction of bauxite ores, by calcining the raw charge material, preferably between 800 DEG C. and 1350 DEG C. and smelting the material with a carbonaceous reducing agent in an electric furnace, the ratio of alumina to silica being 1 to 3 moles of alumina to 3 to 2 moles of silica, thus obtaining molten iron, and a slag containing substantially all the titania, alumina, and silica. The smelting is preferably carried out in an electric arc furnace in which the electrode tips are adjusted so as to be from 1/2 inch above the top of the slag bath to 3 inches below the top of the slag bath.  This prevents segregation of the components of the charge.  Further it is advantageous to arrange the feed of solid down the sides of the furnace, so that the molten slag does not come into contact with the furnace walls. The metallic iron is separated, and the slag is digested with aqueous sulphuric acid, preferably of at least 60% concentration. A solution of aluminium and titanium sulphates, and an insoluble residue of silica is obtained. The residue is removed and the solution is first treated to obtain aluminium sulphate, which may be calcined to the oxide, and then for the recovery of titania. If there is any unreduced iron oxide in the slag, or if the titanium is present as the dioxide, which with sulphuric acid gives the oxysulphate, metallic aluminium is added to the solution in sulphuric acid to reduce the iron oxide to iron, which is precipitated, and to convert the oxysulphate to the sulphate.  In a modification, the slag is digested with dilute sulphuric acid to form a solution of aluminium sulphate, and the residue of silica and titania is then treated with a more concentrated sulphuric acid to give a solution of titanium sulphate. The solutions are then separated, treated to recover aluminium sulphate which may be converted to alumina by calcining, preferably by heating to about 690 DEG C. and finishing at 1000-1100 DEG C., and titania by hydrolysis of the titanium sulphate solution.

Title: System to provide medical electrical stimulation to nervous tissue
Inventor: DUYSENS VICTOR
IPC: A61N1/05
Filed: 2000-07-11
Abstract: A system for providing electrical stimulation to the trigeminal nerve 22 comprises a lead 1,2 and electrodes 3. The electrode assembly 3 features a pair of oppositely disposed curved semi-circular cuffs 4, 5 disposed to conform a lumen 6 therethrough. The ends of each cuff are mounted into a resilient hinge (7, Fig 4) disposed upon the distal end of a lead body 9 through which a lead 1,2 passes. The hinge biases the cuffs towards one another such that the nerve 22 will remain enclosed therein. The hinge is further designed so as to be easily opened so as to spread the cuffs apart. Hinge opening may be accomplished through a specialized implant tool 9, the implant tool being a generally cylindrical tube designed to meet about the lead body. A divergence 98, Fig 4) near the hinge permits the implant tool to engage the lead body in that section and thus forces the cuffs apart by compressing members (11,12 Fig 4) behind the hinge (7 Fig 4 and Fig 5). Alternatively, grip portions on the outside of each cuff may be used to open the Lumen (see Figs.1,2A).

Title: Releasble connector
Inventor: BAKKE STIG
IPC: E21B23/04
Filed: 2000-08-09
Abstract: A connector (10) with an axial bore (12), therethrough has a connecting end (22) for coiled tubing, and a connecting end (20a) for a downhole tool, and is arranged to be released and divided into two sleeve-shaped parts (14 and 16,20). In a spring chamber (44) for a piston body (23, 23a) and with the purpose of delaying release, there is filled lubricating grease, for which extrusion channels are provided. The lubricating grease must first be forced out of the spring chamber (44) by means of the piston body (23, 23a)before the spring (42) thereof can be fully compressed and allow displacement of the piston body into its end position to release an expandable locking ring (17) and release the connector. Because of the delay achieved, the interconnection of the two parts (14 and 16, 20) can be restored, if an unintentional pressure build-up inside the connector ceases before the locking ring (17) has been brought completely out of its active position.

IPC: E21B47/10
Filed: 2000-12-11
Abstract: A subsea wellhead assembly (11) has a conventional tubing hanger (21) attached. An arrangement made up of a production tree (31) and a production module (61) is fitted onto the hanger (21). The bottom of tree (31) fits onto the top of hanger (21) via guide posts (27) and the bottom of module (61) fits onto the top of tree (31) through a guiding funnel (59). A first upward production passage (37) extends through the tree (31) from the production passage of the hanger (21), whilst an annulus access passage (41) extends upwards from the annulus (25) of the tubing hanger (21). A number of valves (39,43,45) may be used to control flow through these passages (37,41). A second production passage (51) extends downwards from the top of the tree (31) to the annulus passage (41) and has an associated lateral passage (53) for the fluid to exit the tree (31). The production module (61) has an upward flow passage (71) that is positioned to fit with first upward production passage (37). The passage (71) leads to a downward flow passage (75) via a cross-over passage (73), with the passage (75) positioned to fit the second production passage (51), 71, 73 and 75 form a flow loop in which one or more flow interface devices can be positioned. During production, well fluid flows up the tubing hanger (21), the tree passage (37) and the production passage (71), through the cross-over passage (73) and then through downward passage (75) into passages 51 and 53 to exit the system. Various fluid interface components may be positioned throughout.

Title: Image Sensor System
Inventor: FASEN DUANE
IPC: H01L33/00
Filed: 2002-07-16
Abstract: The image sensor system includes a colour filter array 14 that is formed by a colour filter process that incorporates a bottom antireflection coating 16 (BARC). The BARC forms a layer that protects the exposed areas of the active image sensing device structure 12 during formation of the colour filter array and thereby preserves the intrinsic transmission characteristics of the active image sensing device structure. The BARC also reduces degradation of metal structures at the exposed surface of the active image sensing device structure. In addition the BARC provides a reliable adhesive surface for the colour filter array, substantially eliminating lifting of the colour filter array resist structures. In some embodiments, the BARC also improves the optical transmission characteristics of one or more of the colour filter array. The bottom antireflection coating may be made from a dyed organic film forming material or a light-absorbing polymeric film forming material.

Title: Arrangement and method for installing a subsea transformer
Inventor: HAFSKJOLD GUNNAR
IPC: E21B41/00
Filed: 2001-07-02
Abstract: The present invention relates to offshore installations, and in particular to an arrangement and a method for use in installation procedures for subsea transformers. In a preferred embodiment of the invention, a central, hole or tube is included in the encapsulation enclosing the transformer which is to be installed. Three core elements of the transformer are arranged symmetrically around the hole or tube forming a triangle or a delta. In the installation process, the transformer is lowered towards a foundation placed on the sea floor wherein a guide pin is mounted. When the transformer has found its way to the foundation, the guide pin will enter the tube, and the transformer will slide down onto the guide line. The tube is terminated by a funnel shaped opening, thus making it easier not to miss the guide pin by the tube opening. The transformer is horizontally oriented by means of orientation keys localized within the tube.
