Title: Targeted delivery of genes encoding antisense polyribonucleotides
Inventor: CHIOU HENRY C
IPC: A61K47/48
Filed: 1994-04-04
Abstract: Molecular complexes for targeting a gene encoding an antisense polyribonucleotide to a specific cell in vivo obtaining production of the polyribonucleotide within the targeted cell, and effecting specific inhibition of the expression of cellular or noncellular genes are disclosed. An expressible gene encoding a desired antisense polyribonucleotide is complexed to a conjugate of a cell-specific binding agent and a gene-binding agent. The cell-specific binding agent is specific for a cellular surface structure which mediates internalization of ligands by endocytosis. An example is the asialoglycoprotein receptor of hepatocytes. The gene-binding agent is a compound such as a polycation which stably complexes the gene under extracellular conditions and releases the gene under intracellular conditions so that it can function within a cell. The molecular complex is stable and soluble in physiological fluids and can be used in antisense gene therapy to selectively transfect cells in vivo or in vitro to provide for production of the antisense polyribonucleotide within the targeted cell, and inhibition of the expression of cellular or noncellular genes.

Title: Shoe press roll for a paper machine
Inventor: SCHIEL CHRISTIAN
IPC: B30B3/00
Filed: 1996-04-11
Abstract: A shoe press roll for a paper machine which, together with a backing roll, forms a press nip through which a press jacket guided over the shoe press roll travels together with a paper web.  The shoe press roll comprises a press shoe which can be pressed by at least one hydraulic element against the backing roll.  The hydraulic element is developed as a cylinder/piston unit that acts between a stationary support member and the press shoe.  The unit includes a first pressure chamber which can be acted on by hydraulic pressure and is in communication via a small diameter throttle point passing through the piston with a second pressure chamber which is open toward the press shoe.  The edge of the piston rests with a sealing surface against the press shoe. Hydraulic pressure is transmitted from the first pressure chamber under approximately static conditions, to the second pressure chamber through the throttle point and thus to the press shoe.  Should the press shoe tilt permitting pressure to escape from the second chamber at the shoe, the throttle point prevents rapid continuous flow of hydraulic pressure out of the first pressure chamber.  The tilting produces a pressure drop in the second pressure chamber which causes the press shoe to apply itself against the cylinder/piston unit as a result of the external pressure applied from the first pressure chamber.

Patent CA-2178158-A1 (CA)
Inventor: KRINKE ANDREAS
IPC: H01K3/06
Filed: 1996-06-04
Abstract: To permit easy assembly of a filament for a halogen incandescent lamp having a filament holder frame (4) to retain an essentially planar filament (11) in position, the frame is made of two pre-manufactured identical frame halves (4a, 4b).          Both frame halves have a cross element (7a, 7b), having a plurality of filament holders (10a, 10b) secured thereto, and two support strut portions (8a, 9a, 8b, 9b) at the ends thereof.  To assemble the lamp, the two frame halves, together with the filament (11), are placed in a suitable jig, and the filament ends are threaded on one of the support strut portions (8a, 8b) of each one of the frame halves.  The filament (11) is hooked on the filament holder (10a, 10b) and, by spreading apart the frame halves, the filament is stretched.  The support strut portions (8a, 8b; 9a, 9b) are then connected by welding, thus completing the frame (4), and retaining the filament in stretched position.  This permits mechanized assembly of the filament (11) in the frame (4) and, hence, inexpensive manufacture; separating the welding steps of the frame from filament connection reduces oxidation on part of the filament.

Title: Process for cooling and cleaning flue gases
Inventor: MUELLER PATRICK
IPC: B01D53/68
Filed: 1996-01-08
Abstract: In order to cool and clean the flue gases from the incinerator of a waste-incineration plant, the invention calls for the gases to be fed, in a first stage (1), as the fluidizing gas into a fluidized-bed reactor (6) into which, at the same time, adsorption agents are fed to remove the gaseous pollutants.  The solid material removed from the fluidized-bed reactor (6) is preferably recycled through a fluidized-bed cooler (15). The conditions in the first stage (1) are optimized for the removal of SO2 in particular, the temperature being kept at over 600 ~C, and the flue gases are further cooled and treated in a second stage (2a, 2b, 2c). In a second fluidized bed at temperatures below 600 ~C, the conditions are optimized for removal of HCl. In addition to optimum cleaning of the gases, the invention also ensures efficient cooling, thus avoiding the problem of corrosion at the heat-transfer interfaces.

IPC: F16L15/04
Filed: 1996-09-10
Abstract: A joint of the integral type includes a male element 1 and a female element 2 with a diameter close to that of the tubes. Each of the elements has two shifted frustoconical threaded sections 4, 5, 6, 7 with vanishing threads at the two ends, by virtue of convergences of frustoconical envelope surfaces 16, 17, 18, and 19 and cylindrical surfaces 20, 21, 22, 23. A central abutment 24 cooperates with the negative- flank threads to reinforce the male/female connection and two internal 27 and external 28 ring-shaped meta/metal tightness zones, preventing the penetration of fluid into the threaded zones from the ends. The threaded joint may be used with tubes for very deep wells for which the reduction of the diameter of the assemblies makes it possible to lower costs, and other tubes for which a problem of the same type may arise.
