Title: Inhibition of pulp and paper yellowing using nitroxides and other coadditives
Inventor: SCHMIDT JOHN ALOIS
IPC: D21H17/07
Filed: 1998-07-14
Abstract: Pulps or papers, especially chemimechanical or thermomechanical pulps or papers, which still contain lignin, have enhanced resistance to yellowing when they contain an effective stabilizing amount of a hindered amine compound which preferably is a nitroxide, a hydroxylamine or an ammonium salt thereof.  This performance is often further enhanced by the presence of one or more coadditives selected from the group consisting of the UV absorbers, the polymeric inhibitors, the nitrones, the fluorescent whitening agents, metal chelating agents, sulfur containing stabilizers, metal salts and diene compounds. Combinations of nitroxides, hydroxylamines or their salts, benzotriazole or benzophenone UV absorbers and a metal chelating agent are particularly effective. Selected derivatives of 1-oxyl-2,2,6,6-tetramethylpiperidin-4-ol and selected hydroxylamine salts are novel compounds and are surprisingly effective for this purpose.

IPC: A63F9/00
Filed: 2000-02-28
Abstract: A novel means and apparatus for a new kind of photography and videography is described. In particular, a wearable camera with a viewfinder suitable for long-term use is introduced. The system, in effect, absorbs and quantifies rays of light and processes this quantigraphic information on a small wearable computer system, then the processed information is re-constituted into light rays emerging to reconstruct the virtual image of objects at nearly the same position in space, or at a coordinate transformed position, as viewed by the wearer of the apparatus. The wearer of the apparatus becomes, after adaptation, an entity that seeks, without conscious thought. or effort, an optimal point of vantage and camera orientation. Because of the wearer's ability to constantly see the world through the apparatus, which may also function as an image enhancement device, the apparatus behaves as a true extension of the wearer's mind and body, giving rise to a new genre of documentary video.

Abstract: The invention concerns an artificial sphincter provided with a valve permanently implanted on a duct or organ whether biological or not during a surgical operation and subsequently easily activable from outside the human body by the patient himself and also easily adjustable from outside the human body during a postoperative session by a doctor. The artificial sphincter valve (17) comprises a rigid and sealed housing (1, 3, 16), provided with a support conduit (11) receiving said duct (1), and a strap (4) compressing said duct against a wall of said conduit, said strap being maintained tight by a spring element (12) pressing on a lower disk (6) bearing a first magnet (9), the whole assembly being mobile in axial translation in said housing. It also comprises an upper disk (14) screwed in said housing forming an axial stop for the first magnet and bearing a second magnet (15). A permanent magnet (18) outside said human body is used to activate the first magnet (9) to slacken the strap (4) and open said duct (2). An electromagnet (27) outside said human body is used to rotate the second magnet (15) and the upper disk (14) to adjust the tension of the strap and the degree of closure of the duct (2). The artificial sphincter is used, for example, to remedy problems related to bladder or bowel incontinence, to modify by remote control the opening of the human pylorus or for the contraction of an organ whether biological or nor.

Abstract: A method and apparatus for reducing operating costs and emissions in a pumping installation. A first step involves providing a flow dividing apparatus capable of dividing flow from a pump. The apparatus has a single inlet and two or more outlets. A second step involves coupling the flow dividing apparatus with a pump of the pumping installation and directing flow from the pump through the single inlet of the flow dividing apparatus. The pump will generate a flow stream from each of the two or more outlets and perform work that, in the absence of the flow dividing apparatus, would have to be performed by two or more pumps. The reduction in the number of pumps used necessarily reduces both operating costs and emissions.

Title: Securing feature activation in a telecommunication system
Inventor: SERKOWSKI ROBERT J
IPC: H04L29/06
Filed: 2000-07-11
Abstract: Periodically sending by a telecommunication controlled application an encrypted message to a licensed server to request permission to run and to obtain a list of permitted features. The license server application is executing on the same processor as the controlled application. Also resident on the same system is a license file which contains a list of applications that are permitted to run, the version number of the permitted applications and a list of permitted features. The license server is responsive to the encrypted message from the controlled application to read and decrypt the license file, read the serial number of the processor controlling the telecommunications system, compare the serial number obtained from the processor with the serial number stored in the license file. If there is a mis-match, no license is granted to the control applications and it will not be allowed to run. If the serial numbers match, then a comparison is made between the version number received from the application and the corresponding version number associated with the application in the license file. If the version number mis-matches, an encrypted message is sent to the application denying it permission to run. If the version number matches, an encrypted message is sent to the application granting it permission to run and listing the permitted features. To decrypt the license file, the license server utilizes a key that is assigned to the license server either globally or on a per system basis.
