Abstract: L'invention concerne des systèmes et des procédés servant à améliorer les performances et le contrôle des émissions de moteurs à combustion interne équipés de systèmes de contrôle d'émission (206) NSR (réduction-accumulation d'oxydes d'azote). Ce système est composé d'un catalyseur NSR (206), d'un dispositif de traitement de carburant (200) situé en amont du catalyseur NSR et d'au moins un orifice d'injection de carburant (208). Le dispositif de traitement de carburant (200) convertit le carburant en un mélange gazeux réducteur comprenant CO et H¿2?. Ce mélange alimente ensuite le catalyseur NSR (206), dans lequel il régénère l'adsorbant NSR, réduit NO¿x? en azote et désulfate éventuellement de façon périodique le catalyseur NSR. Ce dispositif de traitement de carburant (200) comporte un ou plusieurs catalyseurs, ce qui facilite les réactions, telles que la combustion, l'oxydation partielle et/ou le reformage et contribue à consumer le surplus d'oxygène présent dans le flux d'échappement du moteur. Ces procédés concernent la régénération de l'adsorbant du catalyseur NSR. Elle concerne également des stratégies de contrôle de ce système et de ces procédés.

Abstract: Improved control of continuous processes that handle liquids. Data generated by this invention is. used to control gas contents of liquids within optimum ranges, for instance in paper coating processes and in the manufacture of food products (ketchup), personal care products (shampoo), paints, and in any industry where information on entrained and/or dissolved gases, and related parameters such as true density of and gas solubility in process liquids, is employed to optimize processing. The amount of gas in a liquid is determined by subjecting a mixture of an incompressible liquid sample and a compressible gas to three or more, different equilibrium pressure states, measuring the temperature and volume of the mixture at each of the pressure states, determining the changes in volume of the mixture between at least two different pairs of pressure states, and calculating the amount of gas in the liquid sample. The inventive apparatus includes: a reservoir for process fluid; piping through which fluid may be pumped, the piping being under the control of a pressure regulator which is capable of setting at least three different pressures P1, P2, and P3 in the apparatus; at least three fluid control valves V1, V2, and V3; a pressure gauge; a temperature gauge; and a density gauge.

Title: Device for producing film rolls
Inventor: HEIKAUS GERD
IPC: B65H19/22
Filed: 2002-11-28
Abstract: A device for producing film rolls (24), which is in particular suitable for producing coreless film rolls, comprises a roll holder (10) for receiving a film roll (12) comprising a film sheet (14) to be wound off. The film sheet (14) is wound up to a winding mandrel (20) for producing the preferably coreless film roll (24). For producing in particular a coreless film roll (24) the winding mandrel comprises a plurality of radially displaceable holding segments (50) extending in longitudinal direction of the winding mandrel (20). After transfer of the winding mandrel (20), together with the wound-up film roll (24), to a transport means (32), the winding mandrel is transported to a delivery station (46). The delivery station serving for automatically delivering the wound-up film roll (24) from the winding mandrel (20) comprises a displacement means with the aid of which the holding elements (50) of the winding mandrel (20) are displaced into a delivery position. In this delivery position the outer diameter of the winding mandrel is smaller such that the film roll (24) is delivered from the winding mandrel (20) and falls onto a transport belt (60).

Title: Location-dependent information reproduction with adaptation of a geographic selection parameter
Inventor: LLOMBART-JUAN NURIA
IPC: G01C21/36
Filed: 2003-04-17
Abstract: A method for providing an information unit to a user is described, wherein the information unit describes an object having a predetermined spatial relationship to the user. The method includes detecting (50) a kind of movement or a position of the user. Depending on the detected kind of movement or the position of the user, a geographic selection criterion is adjusted (72), wherein, depending on the predetermined spatial relationship of object to user, the geographic selection criterion specifies whether the information unit is provided or not. If a location of the user is located such with respect to a geographic position of the user that the geographic selection criterion is met (56), the information unit for the object is reproduced (63). An advantage is that the concept may be employed in applications in which the user gets into different environments and situations which, in turn, require different geographic selection criteria.

Patent CA-2484962-A1 (CA)
Title: Seat cushion
Inventor: AMBUEHL PETER
IPC: A47C4/54
Filed: 2004-10-15
Abstract: A seat cushion with a seat surface wall area and a bottom surface wall area has a bulge-shaped transition wall area which joins the seat surface wall area to the bottom surface wall area. Thus, there is a fluid-tight cushion which can be filled with air via a sealable fill opening. In two adjacent spaced apart areas the distance of the transition wall area from the middle of the seat cushion is increased, by which in overhead view lens-shaped areas are formed which project laterally beyond the essentially circular outline shape of the seat cushion which is otherwise determined by the transition wall area. These projecting areas are supports for the thighs of an individual sitting on the seat cushion. Even for a small diameter of the generally circular surface-shaped seat cushion this yields good sitting comfort, since the thighs are supported at least in the area adjoining the buttocks by the projecting supports, as would be the case otherwise only for a seat cushion with an altogether larger diameter.

Patent CA-2488750-A1 (CA)
Inventor: YANG RUI
IPC: H04B17/40
Filed: 2003-06-05
Abstract: An analog/digital gain control device (30) avoid some of the requirements associated with the nature of a closed-loop AGC circuits and which meets the remaining requirements without much difficulty uses an analog to digital conversion method that increases the number of effective ADC bits by compressing the baseband input analog signal using a logarithmic circuit (34 ). After the compressed analog signal is converted into a digital signal, a digital anti-log process or look-up table (LUT) (42) is used to expand the digital signal back to the original linear scale. The word size of the outpu t of the anti-log process is larger than the input word size due to the nature of the anti-log function. To reduce the word size of the digital signal an open loop normalization technique can be applied.
