Abstract: Selon l'invention, il est prévu afin d'exploiter un dispositif de stockage temporaire, par exemple d'articles plats stockés temporairement en rouleaux, notamment de produits d'impression, au moins un dispositif de positionnement (5) et au moins un dispositif d'orientation (6). Le dispositif comprend une pluralité de postes de bobinage (1), une pluralité de supports de rouleaux (2) et une pluralité de points de stockage (2,1, 2,2) pour les supports de rouleaux (2). Les points de stockage (2,1, 2,2) sont disposés sur une pluralité de parcours de transport primaires (3) parallèles. Ces parcours de transport primaires (3) coupent au moins un parcours de transport secondaire (4,1, 4,2). Les entrées de postes de bobinage (1) sont placées le long d'un parcours de transport secondaire (4) et sont alignées sur les parcours de transport primaires (3). Le dispositif de positionnement (5) peut être déplacé de manière active le long des parcours de transport primaires (3), afin d'enlever les supports de rouleaux (2) en les tirant et de les positionner par secousses dans des points de stockage (2,1, 2,2) et des postes de bobinage (1).

Title: Fish feed with increased nucleotide content
Inventor: BURRELLS CHARLES
IPC: A23L7/10
Filed: 2000-10-11
Granted: 2011-03-22
Abstract: The present invention provides for the improved uptake of feed additives, pigments for use in colouring the flesh and the like. This improved intestinal uptake of foodstuffs and additives is effected through enhancing the development of the intestinal tract. Specifically the present method comprises of feeding fish with a diet which has an augmented level of nucleotides present therein. The nucleotides may be selected form the group consisting of uracil, guanine, cytosine, thymine, adenine and mixtures thereof. The resultant improvement in the development of the intestinal tract leads to an improvement of the intestinal surfaces to absorb nutrients and/or dietary additives, this increase being at least partly due to an increase in gut surface area, for example through an increase in villus height.

Abstract: A method for optimizing the production of a petroleum well is provided. The petroleum well includes a borehole, a piping structure (24) positioned within the borehole, and a tubing string (26) positioned within the borehole for conveying a production fluid. Production of the well is optimized by determining a flow rate of the production fluid within the tubing string (26) and determining a lift-gas injection rate for the gas being injected into the tubing string. The flow rate and injection rate data is communicated along the piping structure of the well to a selected location (44), where the data is collected and analyzed.

Abstract: The invention relates to a method for improving smart antenna array coverage. Arbitrary beam forming of an antenna array can be implemented by adjusting n antenna units beam forming parameter W(n), based on difference of size and shape between coverage required in engineering design and actually realized coverage. The method includes: setting an accuracy of W(n), i.e. an adjusting step length, setting a set of initial values W0(n), an initial value of mean-square error .epsilon.0, setting counting variable, setting threshold of ending adjustment M and maximum emission power of an antenna unit T(n). With the settings, a loop for W(n) adjustment is executed. A step-by-step approximation method is deployed for adjusting antenna radiation parameters, based on the minimum mean-square error criterion. Finially, an actual coverage of an antenna array approximates to the required coverage, under local optimization condition.

Abstract: Process for manufacturing an assembly made of a composite material and wing and stabilizing element obtained by this process.      The junction zone for a part (P) made of a composite material comprising two parts (A1, A2) in which the principal directions intersect at a non-singular angle, is made in a single operation by continuous lay-up. The 0° directions of the lay-up coordinate systems (R1, R2) of the parts (A1, A2) are oriented such that these directions make an angle of close to 180°- .theta.°, where +.theta.° represents the other directions of the lay-up coordinate systems (R1, R2).      Thus, the layers of fibers oriented at 0° in one of the coordinate systems correspond approximately to a lay-up direction of +.theta.° in the other coordinate system.

Granted: 2015-02-10
Abstract: Methods, devices and circuits for detecting malfunctions in stepper motors. A signal from a driver circuit to a stepper motor that is proportional to the current in the windings of the stepper motor is detected. This signal is then amplified and integrated for ease of comparison. The resulting signal is then compared to a specific entry in a table of values with each entry in the table corresponding to an operating profile of the stepper motor. If the resulting signal does not correspond to the operating profile for which the motor a configured, the stepper motor is jammed. A suitable alarm and a corresponding sequence of actions may then be triggered.
