  • Publication number: 20250085308
    Abstract: A tachometer system for high-torque rotor for a handheld or spindle-mounted pneumatic tool. There are three main components of the tachometer system. This first main component is a measuring module that includes a photodetector electrically coupled to a cable. The measuring module is fastened inside an air turbine motor assembly with a plurality of exhaust ports. The measuring module is sized to fit within an exhaust bore of the air turbine motor assembly. In one example, the measuring module includes a photodetector mounting plug for firmly holding the photodetector in the exhaust bore of the air turbine motor assembly. Another example of the measuring module includes a photodetector mounting plug for firmly holding the photodetector in the exhaust bore of the air turbine motor assembly.

  • Patent number: 9835098
    Abstract: The present invention discloses a method of introducing fuel into a diesel engine for combustion within the engine. A natural gas in liquid form is injected into the engine for combustion therein with diesel fuel so as to maintain a natural gas concentration derived from the liquid in the range of greater than 0.6% to 3.0% of air intake by volume of natural gas. Suitable gases include natural gas, methane or substantially methane gas mixtures and substitute natural gas such as propane air mixtures providing a mixture with similar combustion properties to methane/natural gas.

  • Patent number: 9447891
    Abstract: A valve includes an interior portion and a nozzle passage. The valve further includes a poppet having a first stage portion and a second stage portion. The poppet has a closed position in which the first stage portion and the second stage portion seal the interior portion of the valve from the nozzle passage. The poppet also has a partially open position, in which the first stage portion of the poppet is spaced from the second stage portion of the poppet, and defines a first fluid passage between the interior portion of the valve and the nozzle passage. Additionally, the poppet has a fully open position, in which the second stage portion of the poppet is spaced from the nozzle passage of the valve, and defines a second fluid passage between the interior portion of the valve and the nozzle passage.

  • Patent number: 9249745
    Abstract: Disclosed is a method of injecting natural gas into a diesel fuel engine for combustion with diesel fuel therein. One aspect includes injecting natural gas into an air-stream of an engine air intake or manifold, measuring the percentage of natural gas injected into the airstream or other efficiency gauge, varying the rate of injection of natural gas into the airstream in response to the measured percentage of natural gas therein and injecting the natural gas at a pre-determined rate so as to maintain an natural gas concentration in the air intake stream in the range of 0.6% to 3.0% by volume of natural gas.

  • Publication number: 20080064485
    Abstract: Gaming machines, systems and methods that present reel-based games are disclosed. Reel symbols can move or appear to move from one gaming reel to another gaming reel. Such reel symbols may include lenticular images, such as those that are implemented onto a medium via a lenticular process, whereby the medium is then applied to various gaming machine reels so that a viewer can perceive effects such as motion and depth. The medium can be a multi-image sheet containing regions of overlapping images where different images are visually predominant at different viewing angles, and the movable base can comprise a gaming reel. Multiple gaming reels can be used, and can be adapted to rotate in any direction.

  • Publication number: 20060218493
    Abstract: A method, system and device for controlling a display are disclosed. Data is examined, which correspond to an image to be shown with the display. Upon determining that said data comprise a critical item corresponding to an element of the image, the critical item is shown with an uncluttered view. Non-critical items corresponding to elements of the image are attempted to be shown as well, such that the critical item is not obscured and the image remains uncluttered.

  • Publication number: 20060052152
    Abstract: Inexpensive yet effective three-dimensional image displays for gaming machines are disclosed. Images are implemented onto a medium via a lenticular process, and the medium is applied to various gaming machine surfaces whereby a viewer can perceive effects such as motion and depth. Steps can include developing a game theme, designing visual images for this game theme, generating digital files containing these visual images, previewing these digital files, modeling the visual images in a computer assisted simulation, implementing these visual images onto a medium, attaching the medium to a movable base, and installing the movable base to the gaming machine. The medium can be a multi-image sheet containing regions of overlapping images where different images are visually predominant at different viewing angles, and the movable base can comprise a gaming reel. Multiple gaming reels can be used, and can be adapted to rotate in any direction.
