Title: Valve assembly for carpet extractor
Inventor: BOLL DAVID J
IPC: A47L1/03
Filed: 2000-01-06
Granted: 2004-11-02
Abstract: A carpet extractor valve assembly (340,522) alternately directs cleaning solution to a base-mounted spray bar (74,526) or to a remote distributor (438,614) of an accessory tool (16,524). The valve assembly includes an inlet port (344), which receives cleaning fluid from a handle-mounted reservoir (14,574), and first and second discharge ports (400, 442), connected to the spray bar and the accessory tool, respectively. First and second valve members (352,354) include first and second poppets (362, 444), which are biased by a spring (384) to normally-closed positions in which the first and second discharge ports are sealed. A trigger-operated actuation rod (410) actuates the first valve member to release cleaning fluid to the spray bar. A quick connect coupling (464,466,608,610) connects the remote distributor with the second discharge port and opens the second valve member thereby. In one embodiment, a cleaning solution pump (480), mounted in a pump housing (490) over a base assembly A, is coupled between the valve assembly (340) and the remote distributor (438). In another embodiment, a pump (520) is connected between a cleaning solution tank (574) and the valve assembly inlet port and pressurizes cleaning fluid for both the spray bar (526) and the remote distributor (614).

Abstract: Cette invention porte sur un procédé de production d'un article tel qu'une feuille ou un corps de canette de boisson, la surface de cet article étant pourvue d'une grille de diffraction optique de sorte que la surface génère des couleurs à interférences visibles lorsqu'elle est éclairée par une lumière blanche diffuse. Le procédé consiste à produire cet article à partir d'un matériau en une ou plusieurs étapes, et dans une étape, un motif en relief formant une grille de diffraction est imprimée sur la surface de l'article au moyen d'un outil dont la surface d'appui est dotée d'un motif en relief correspondant. Le motif de la surface d'appui est constitué de nervures et/ou gorges formées sur ou dans celle-ci qui sont des lignes parallèles droites séparées par des distances appropriées à la diffraction de lumière. Lors de l'impression du motif, l'article est déplacé par rapport à l'outil dans un sens longitudinal et l'outil est orienté de sorte que les nervures et/ou gorges formant le motif de diffraction sont alignées parallèlement au sens de déplacement de l'article. Tout étirement ou déformation de l'article obtenu lors de l'impression de la grille de diffraction se produit dans le même sens que les lignes de diffraction de sorte que le motif ne soit pas détruit ou déformé, mais soit seulement atténué dans le sens longitudinal, ce qui n'affecte pas les effets d'interférences du motif (régis par l'espacement des lignes). Le procédé de coloration qui s'en suit permet d'obtenir un article attractif et peut être réalisé à haut rendement.

Abstract: A method and control apparatus for an internal combustion engine that allows an operator to calibrate engine performance relative to an engine operating characteristic. The control apparatus comprises a base engine control map that correlates values of the characteristic with values of a base engine control, a trim control map that correlates the values of the characteristic with values of a trim control, an engine control unit that obtains from the base engine control and trim control maps the respective base engine control and trim control values that are based on the characteristic value, and a panel that is operatively coupled with the engine control unit and includes a first switch regulating a trim signal supplied to the engine control unit. The trim control map is separated from the base control map. The engine control unit calculates a n engine operating control value based on the obtained values. The calculated engine operating control value is supplied to the internal combustion engine to vary the engine performance. The first switch is adapted to be manipulated by the operator. And the trim signal causes the engine control unit to modify the trim control values in the trim control map.
