IPC: F02F3/10
Filed: 1999-08-02
Abstract: L'invention concerne un moteur à combustion interne adiabatique pouvant augmenter notablement l'efficacité thermique par comparaison avec un moteur à combustion interne classique. Le moteur à combustion interne de l'invention peut facilement donner un moteur à explosion adiabatique (du type moteur à essence ou moteur diesel rotatif) relativement bon marché et durable. La perte de refroidissement est réduite ou éliminée par isolation de la chambre à combustion d'un moteur alternatif ou d'u moteur rotatif, ce qui diminue d'autant la consommation de carburant et permet une économie d'essence plus importante que pour les moteurs classiques. Un matériau résistant à la chaleur est disposé sur la surface de la chambre à combustion et un matériau isolant est disposé entre le matériau résistant à la chaleur et un matériau de base du moteur (alliage d'aluminium ou fer) pour conférer une isolation bon marché et durable, et empêcher une élévation de la température (au-delà de 850 ·C) d'une paroi de la chambre à combustion pouvant provoquer un allumage prématuré dû à l'isolation. Pour ce faire, on établit entre un taux de compression et un taux de dilatation une différence telle que le taux de dilatation soit supérieur au taux de compression, ou on diminue un rapport d'un mélange air-carburant plus dense ou la quantité maximale de prise d'air.

IPC: B60P3/10
Filed: 2002-01-18
Abstract: The present invention is a boat guiding means comprising two boat guiding mechanisms that are attachable near the rear of each side of a standard boat trailer. When the trailer is backed down a boat ramp into the water (with or without the boat), buoyant guiding arms on the guiding mechanisms pivot upward so the guiding arms remain approximately parallel to and near the surface of the water when the trailer has been submerged to an appropriate depth for loading or unloading a boat. The guiding arms thus provide a guiding surface near the rear of both sides of the trailer to prevent the stern of the boat from wandering during loading or unloading of the boat from the trailer.

Title: Apparatus and method for gray level printing
Inventor: ZEISE ERIC
IPC: G03G15/043
Filed: 2001-05-15
Abstract: A copier or a printer (10) includes a controller 16/30 with a rendering algorithm that groups sets of adjacent pixels into sets of adjacent cells where each cell corresponds to a halftone dot of an image. The algorithm operates in conjunction with a gray scale printhead (22). In sending data to the printhead, the controller (16) parses a scanned image and set the exposure for each pixel in accordance with a growth and density program. The algorithm selectively grows halftone dots from zero size to a desired size equal to or less than a maximum size. It repeats this step for the rest of the pixels until the cell is at its desired size and at an initial density. If a higher density is desired, the algorithm selectively adjusts the fully grown cells by sequentially increasing the level of exposure of each pixel in the cell. The image is developed with developer including a hard magnetic carrier and toner.
