Abstract: Digital signatures are not valid indefinitely but only during the validity periods of their authentication certificates. This poses a problem for electronic information objects that are intended to have legal weight for periods longer than the remaining validity period of a signature. There are thus provided methods of handling stored electronic original objects that have been created by signing information objects by respective transfer agents, submitting signed information objects to a trusted custodial utility, and applying to each validated information object a date-time stamp and a digital signature and authentication certificate of the trusted custodial utility. One method includes re-validating an electronic original object by verifying the digital signature of the trusted custodial utility applied to the object and applying to the re-validated object a current date-time stamp and a digital signature and current authentication certificate of the trusted custodial utility. Another method includes creating an object-inventory from at least one stored original object, including an object identifier and a signature block for each object. A time stamp and a signature and certificate of the trusted custodial utility is applied to the object-inventory. Other methods involve handling information objects that are transferable records according to specified business rules, which avoids that copies of the transferable records can be mistaken for originals.

Title: Process for producing highly homogeneous cellulose solution
Inventor: LEE TAE-JUNG
IPC: C08J3/11
Filed: 2002-08-28
Granted: 2006-07-11
Abstract: Disclosed is a process for producing a highly homogeneous cellulose solution, in which a mixture of powdered cellulose with polyvinyl alcohol powder is fed in conjunction with concentrated liquid NMMO into a kneader or an extruder to produce the highly homogeneous cellulose solution.      Alternatively, a kneader may be used to produce a swollen cellulose/polyvinyl alcohol paste, which is then subsequently moved into an extruder to produce the highly homogeneous cellulose solution. The cellulose solution is extruded through a nozzle into a cellulose fiber. The process is advantageous in that the highly homogeneous cellulose solution can be rapidly and inexpensively produced because the cellulose solution is produced without a vacuum distillation step or separate swelling step, and formation of fibrils is prevented, and thereby cellulose fibers with excellent flexibility and strength are produced from the cellulose solution.

Abstract: When manufacturing waveguides, for example densely located waveguide channels, for electromagnetic waves such as microwaves, the channels are produced from rod-shaped bodies (1) of a material permeable to the waves and non significantly attenuating the waves. The bodies (1) can for example project from a base plate (3) and their side surfaces are coated with electrically conducting material but not their free end surfaces (5). The interior of the bodies form the waveguiding channels, which have their walls formed from the layer of electrically conducting material. By giving the rod-shaped bodies suitable shapes for example an antenna side or half of a waveguide antenna can be manufactured. The rod-shaped bodies can before applying the electrically conducting material be coated with one or several layers of non-attenuating and non-conducting lacquer filling pores and smoothing the surface of the bodies. Thereby, the layer of electrically conducting material obtains a smooth transition surface to the material of the bodies giving the channels good waveguiding characteristics. If the material used in the bodies has a strong surface porosity, the channels formed from the rod-shaped bodies become strongly attenuating to the electromagnetic waves. A set of such bodies located at the sides of each other and having suitable dimensions of the bodies gives an element working strongly attenuating to the electromagnetic waves.

Granted: 2008-03-11
Abstract: The present invention generally provides a closed feedback system for operating peripheral devices in response to environmental conditions. Illustrative environmental conditions include well bore pressure, line pressure, fluid levels, flow rates and the like. In one embodiment, a flow controller (170) disposed in a fluid line (155) is operated in response to operating variable readings (e.g., pressure and/or flow rate) taken in the flow line and/or a well bore. The variable measurements are then compared to target values. If necessary, the flow controller is closed or opened to control the rate of fluid flow through the flow line and thereby achieve the desired target values. In another embodiment, the operation of a pump motor (135) is monitored. Operating variables, such as voltage, current and load, are measured and compared to target values. In the event of a difference between the actual values of the variables and the target values, the flow controller is adjusted to affect the head pressure on a pump being driven by the motor. In some cases, the motor operation may be halted or otherwise adjusted.

Abstract: L'invention concerne un procédé et un arrangement destinés à l'émission de trames d'information numérique sur une connexion de communication hertzienne entre un émetteur et un récepteur. Dans l'émetteur, une certaine séquence de bits, dans chaque trame d'information numérique, est codée par convolution et perforation (112) avant émission de la trame sur une connexion de communication hertzienne. Après réception de la trame sur un connexion de communication hertzienne, le récepteur décode et déperfore (211) la séquence de bits dans chaque trame d'information numérique, préalablement codée et perforée. L'émetteur arrange de nouveau (411) la séquence de bits à l'intérieur de chaque trame d'information numérique, qui doit être codée et perforée, avant son codage et sa perforation (112). L'ordre de réarrangement est un de ceux dont on a trouvé qu'il produit, durant le codage par convolution avec un certain code et durant la perforation avec une certaine structure de perforation, une séquence codée et perforée dans laquelle la probabilité statistique d'erreurs d'émission présente un comportement prédéfini (701). Dans le récepteur, la séquence de bits à l'intérieur de chaque trame d'information numérique, ainsi réarrangée dans l'émetteur, est réarrangée de manière inverse (611) de façon que l'effet du réarrangement dans l'émetteur sur l'ordre mutuel des bits de la séquence soit annulé, après décodage et déperforation de la séquence de bits.

Abstract: An anti-rewet press fabric (10) for paper and board machines includes a barrier layer (27) such that during compression in the press nip, the water is forced through the barrier layer (27), but is prevented from flowing, back to the paper web (24) during expansion. The barrier layer (27) comprises a continuous material possessing, for example square, rectangular, tetrahedral, circular or oblong conical inclusions (30) with a smaller opening on the bottom than on the top of the structure. Each of these "funnels" (30) effectively constitutes a one-way valve and creates a vacuum to prevent re-absorption of water by the paper sheet. Under pressure, the structure of the barrier layer (27) allows water to flow into the cones (30) and out of the smaller opening in the bottom. Upon expansion, the smaller opening in the bottom of the structure restricts backward water flow and creates a vacuum on the other side. The vacuum increases water retention in the press fabric (10) and prevents rewetting of the paper sheet (24). Another embodiment of the invention is described herein, wherein the barrier layer (27) exists as a separate fabric fed through a press section. In this embodiment, the "separate fabric" can just be the "conical inclusion sheet" itself. That is, the sheet itself constitutes an inventive belt having' anti-rewet properties.
