Title: Method for wrapping foodstuffs and wrapping vessels thereof
Inventor: RHEE YEONGWON
IPC: B65D75/52
Filed: 2000-07-19
Abstract: A method for wrapping foodstuffs and wrapping vessels thereof are disclosed. In the method, a foodstuff is temporarily sectioned into a plurality of portions while indicating caloric content on each of the portions prior to wrapping the foodstuff with a wrapping vessel. Thus, people are allowable to consume one or more measured portions containing a desired content of calories. On the other hand, a wrapping vessel for foodstuffs are sectioned into a plurality of segments while indicating calories on each of sectioned portions of a wrapped foodstuff. In the above wrapping vessel, the caloric content is expressed separately on each of the sectioned portions while indicating the caloric content of each portion or total caloric contents of partially divided portions. The invention also provides a wrapping vessel for foodstuffs, having a calorie scale on its sidewall. In such a case, the calorie scale indicates caloric content of portions of a foodstuff within the wrapping vessel.

Abstract: L'invention concerne une méthode et un appareil permettant d'infuser de façon continue à un sujet une dispersion dans laquelle la phase dispersée et sensible à la flottation ou à la sédimentation. Cette dispersion est fournie de façon régulée à partir de l'extrémité supérieure ou inférieure d'un récipient d'administration disposé dans une position sensiblement verticale, par exemple une seringue (2). Cette dispersion est ensuite ajoutée à un liquide de perfusion, par exemple à partir d'un minisac pour perfusion intraveineuse (8), avant d'être administrée au sujet. Par rapport à un récipient d'administration horizontal, tel qu'une seringue placée dans un pousse-seringue classique, la position verticale du présent dispositif de distribution maximise la distance sur laquelle la flottation ou la sédimentation peut se produire, ce qui réduit sensiblement les effets de la séparation pendant une durée de temps donnée.

Title: Method of improving steering performance robustness utilizing mass non-uniformity in tire/wheel
Inventor: CROISSANT BERNARD
IPC: F16F15/32
Filed: 2002-07-03
Abstract: The invention relates to methods for improving vehicle steering performance and robustness of that performance through control of non-uniformities in the vehicle's tires, wheels and tire/wheel assemblies as a way to overcome the tendency of many vehicle types to undergo "steering performance loss." While minimizing lateral force variations (e. g. , couple imbalance), a controlled amount of radial and/or tangential force variation is induced in one or more tire/wheel assemblies by means of mass non-uniformity, dimensional non-uniformity, and/or stiffness non-uniformity. For mass non-uniformity, the preferred method includes imparting a controlled amount of excess mass to tires, especially in the tread region, by means, for example, of a heavy splice, an extra fabric piece, or a sector of a tire component having excess mass. The excess mass is meridionally symmetric so as to induce static but not couple imbalance, thereby imparting a "residual static imbalance" (RSI) to -the tire. Beneficial tangential and/or radial force variations will result in the use of such a tire, even if the tire/wheel assembly is balanced by weights added to the wheel. A method of determining steering performance robustness for a vehicle/wheel/tire construction combination comprises conducting a series of steering performance tests of the vehicle, wherein at least one of the tire/wheel assemblies has its balance condition changed for each test through a progression of values from values favorable to steering performance (e. g., RSI), through neutral values (balanced), to values unfavorable to steering performance (e.g., couple imbalance).
