Abstract: A piston is disclosed, for use in an internal combustion engine, including an insulating guide formed therein for receiving an electrode. The electrode has a body, and at least one spark lead coupled to the body for inserting into a channel formed in the insulating guide. Electrical power is supplied to the electrode by a power plug inserted through a power plug opening in the wall of the combustion chamber of the internal combustion engine. When electric power is supplied to the power plug a first electrical arc is generated between the power plug and the body of the electrode, and a second electrical arc is generated between the tip of each one of the spark leads and an associated arc insert disposed in the piston adjacent the end of the insulating guide. Optionally the electrode is insertable and removable from the piston through the power plug opening.

The asymmetrical arrangement of the rows of lens elements in the array with respect to a seam in a color separation element of the projection system substantially reduces the vertical banding in the projected image.

Abstract: This invention is a family table game, which has the function to become portable. It develops ones ability to identify detailed play pieces 24 by the sense of touch, exciting a players mental ability toward learning about these objects, challenging players sensory perceptions and mental imaging skills while improving finger dexterity. The game uses miniature or larger than life renditions of well known objects, man or nature created, as game pieces 24 played with three dimensional embossed knowledge cards 26. Game pieces sit in a circular, dome shaped container FIG. 1 out of view of player. Player spins card housing 30 (holding the interchangeable game cards 26) which stops randomly under view window 32. Player views or feels raised relief images on card 26 or reads corresponding descriptive text, starts timer 14 and begins searching through container (FIG. 4), using the sense of touch to find matching play pieces 24, earning points for each piece found in time.

Abstract: A coupling device for transferring fluid pressure from a first coupling element to a second coupling element is disclosed, wherein both coupling elements have end faces facing each other which can be moved against each other. Each coupling element comprises a cavity that runs into an opening at the end face and which may be coupled with the cavity of the other coupling element for transferring fluid. In each cavity, a piston is guided movably in axial direction, wherein both cavities have sealing surfaces facing toward the other coupling element that communicate with the opening of the end face and against which the respective piston can be moved with a counter surface for sealing. Each of both pistons is biased toward the other piston by a spring into a sealing position in which the piston rests with its counter surface against the sealing surface.

Abstract: A fluid delivery system includes one or more measure modules for measuring and delivering predetermined volumes of one or more different fluids. Each measure module includes a fluid inlet port, a retention vessel, an overflow aperture to allow fluid in excess of the desired volume to flow out of the vessel, and an outlet port for dispensing the retained fluid. A calibrating rod adjustably occupies a portion of the volume of the vessel to facilitate precise adjustment of the volume of fluid dispensed by the measure module. In one particular embodiment, a blender includes a plurality of measure modules whose outputs are coupled together to produce a mixture having a composition defined by the relative capacities of the vessels of the various measure modules. In another particular embodiment, one blender dilutes a chemical concentrate, and provides the diluted mixture to another blender, which further dilutes the mixture.

Abstract: An automated cell is provided for handling parts received in part carriers. The device comprises a working space closed to the outside, within which a first, second and third stack position are sequentially arranged. A transfer device is provided with a first linear axis extending in a horizontal direction and a second linear axis coupled thereto extending in vertical direction. A bulkhead wall is arranged between the first and the second stack position, which together with a driveable hood guarantees a closure free of contact when the door on the front side of the device is opened. Handling procedures within the working space can then be decoupled from loading and unloading operations at the first stack position. The automated cell is very space-saving and inexpensive and also allows a stack-specific logistics.

The aberration compensation element is disposed in either or both of the polarized illumination beam and the imaging beam. The separation of the illumination beam and the imaging beam provided by the off-axis architecture facilitates the use single-pass aberration compensation elements, including liquid crystal compensation films and wave retarders. A multi-color projection system is also disclosed.
