Abstract: The invention shows the method to create a high accuracy topographical scale model for the purpose of science by using multi-layered/laminated materials. The invention is based on and involves the following steps:      The geometry and the data of terrain are measured, collected, and recorded;      The data is entered into a computer and design components are added, if needed; Based on these data a three-dimensional surface is created;      A block of multi-layered/laminated materials made of a combination of veneers, or machinable dividers/layers, laminated one on the top of another, is constructed.        Based on the three-dimensional surface, a program for a C.N.C machine is generated;      Based on the program, the C.N.C. machine cuts/removes the excess material from the block of multi-layered materials.      The three-dimensional surface, contour lines, elevations, outlines, and edges are then exposed automatically and are easy visually measurable.

Granted: 2008-09-23
Abstract: A window assembly which includes at least some components which may be assembled in a snap-fit manner. In certain example embodiments, a combination of rotation/pivoting insertion, and a snap-fit assembly engagement of one or more components may be utilized in assembly. For example, a component may be engaged with a portion of another component, and then rotated and/or pivoted about a pivot axis until a portion of the component becomes engaged with a part of the window in a snap-fit manner. The combined use of rotation/pivoting about a pivot axis and snap-fit engagement allows for self-alignment to be realized during assembly thereby simplifying the assembly process.

Title: Air clamp stabilizer for continuous web materials
Inventor: MOELLER STEFAN
IPC: D21F7/00
Filed: 2002-10-22
Granted: 2010-06-29
Abstract: A device (10) for non-contact support of a continuous moving web (38) of .  material employs an air clamp stabilizer (10) that includes a Coanda slot (18) and a backstep (16) that is located downstream of the direction of the airflow extending from the Coanda slot (18). This configuration permits a Coanda jet to expand and to create an additional suction force. Vortex formation may also occur which further contributes to the strength of the suction force. As the web (38) passes the stabilizer, an area of the web material rides on an air bearing that is maintained above the stabilizer surface (12A,12B,14) and downstream of the backstep (16).

Granted: 2010-10-19
Abstract: The invention is related to an arrangement that is designed to govern inlet and outlet gas mixtures and is used mainly in four stroke combustion engines.  Already existing designees is of a nature that they limit the performance of the four-stroke engine mainly as a result of the weight and its flow-technical design. The invention resolve this problem mainly as a result of that the new valve is lighter and has a better flow-technical design. This is a result of that the new valve design allows both the inlet and outlet gas mixtures to flow inside and through the valve body (find drawing A2) thus as a result the valve design is lighter and has an higher efficiency due to the flow-technical design that allows for that no valve shaft is put in the middle of the flow path. The invention is mainly used in the transportation industry.

Abstract: S'agissant de la spectrométrie de masse, l'invention concerne un procédé et un dispositif pour la fragmentation d'ions avec un degré relativement élevé de résolution et d'efficacité. La technique consiste à piéger les ions dans un piège d'ions linéaire, dans lequel la pression de fond ou de gaz neutre est de préférence de l'ordre de 10?-5¿ torrs. Les ions piégés sont soumis à une excitation résonante pendant une durée relativement longue, par exemple pendant plus de 50 ms, selon des niveaux d'excitation relativement faibles, par exemple moins d'un volt ¿(0-pk)?. La technique décrite permet une dissociation sélective des ions, selon une discrimination élevée. On peut atteindre une grande efficacité de fragmentation en superposant un champ multipôle de rang supérieur sur le champ HF quadripolaire utilisé pour le piégeage des ions. Le champ multipôle, de préférence octopolaire, amortit le mouvement oscillatoire radial des ions soumis à l'excitation résonante à la périphérie du piège. Cela réduit la probabilité de voir les ions éjectés radialement depuis le piège et augmente donc la probabilité de dissociation induite par collision.

Abstract: A computing machine includes a first buffer and a processor coupled to the buffer. The processor executes an application, a first data-transfer object, and a second data-transfer object, publishes data under the control of the application, loads the published data into the buffer under the control of the first data-transfer object, and retrieves the published data from the buffer under the control of the second data-transfer object. Alternatively, the processor retrieves data and loads the retrieved data into the buffer under the control of the first data-transfer object, unloads the data from the buffer under the control of the second data-transfer object, and processes the unloaded data under the control of the application. Where the computing machine is a peer-vector machine that includes a hardwired pipeline accelerator coupled to the processor, the buffer and data-transfer objects facilitate the transfer of data between the application and the accelerator.
