20110192341 | TANK LEVEL INDICATOR - Tank level indicators are known, having a sensor housing in which a resistance card having a resistance strip, and a wiper acting with the resistance path and rotatable about an axis of rotation. The variable rotating resistance is encapsulated relative to the fuel in the sensor housing, so that no fuel can enter the sensor housing. It is disadvantageous that the wiper slides dryly against the resistance path, because this gives rise to increased friction and increased wear on the resistance path. The wear particles collect in the sensor housing, and can negatively influence the contact between the wiper and the resistance path. According to the invention, the protection of the tank level indicator relative to particles or ice crystals is improved. It is also ensured that particles or ice crystals that enter the tank level indicator can flow out of the housing of the tank level indicator. According to the invention, the sensor housing having at least one fluid inlet in an upper portion and at least one fluid outlet in a lower portion. | 08-11-2011 |

20120186508 | BALLOON FILL GAUGE - A balloon fill gauge for a balloon made of elastomeric expanding material has a base sheet with balloon filling indicia thereon that is temporarily tackable on to the balloon face material. An indicator tab with two ends having one end temporarily tackable onto the balloon material has its other end slideably interlockable with the base sheet. An indicator mark on the tab is alignable with the balloon filling indicia to indicate when the balloon is full as the tacked base sheet and tacked indicator tab move apart during the filling of the balloon. The balloon fill gauge alternatively may have an elongate non-stretchable indicator tab having two ends tackable onto the balloon material which physically acts to visual indicate when the balloon is full by snapping in two, popping off the balloon or changing color. Alternatively, the balloon filler gauge may include a base sheet with a balloon filling indicia temporarily tackable onto the balloon which is indexed with an expansible indicator ink mark on the balloon alignable with the filling indicia to indicate upon expansion of the ink mark when the balloon is full or the ink otherwise changes color. | 07-26-2012 |
20120260844 | Angled Gauge Head for Liquid Level Sending Unit - A tilted gauge head for indicating liquid level within a container is operatively connectable to a liquid level sending unit. The gauge head includes a mounting base adapted for connection to the container, an indicator dial assembly operatively connectable to the liquid level sending unit for indicating liquid level, and at least one bracket with a rear mounting wall connected to the mounting base and a front mounting wall connected to the indicator dial assembly. The mounting walls are oriented at an acute angle with respect to each other such that the indicator dial assembly is oriented or tilted at the acute angle with respect to the mounting base. In this manner, the indicator dial assembly can more easily be viewed by a user from an angle to thereby reduce parallax reading errors. | 10-18-2012 |
20140230718 | LIQUID REDUCTION TIMING DEVICE - Disclosed herein is a liquid reduction timing device useful for cooking. More specifically, the disclosed liquid reduction timing device indicates to a user that a liquid has been reduced to a predetermined level when the level of the liquid is equal to the station of a movable indicator. | 08-21-2014 |
20150053130 | Fluid Level Indicator for a Lined Bulk Material Container - A level indicator for a container that is lined with a membrane for holding fluid, and which has a wall with an aperture formed through it. A frame is attached to the container wall adjacent to the aperture. A plunger is engaged with the frame, and moves between an extended position, where the plunger extends through the aperture and into the interior of the container, and a retracted position, where the plunger does not substantially extend into the interior of the container. An elastic member between the frame and the plunger urges the plunger to the extended position. A visual indicator is driven by the plunger between an indicating position and a non-indicating position. The force of the elastic member is selected to enable the membrane, under static pressure of fluid within the container, to urge the plunger to the retracted position. | 02-26-2015 |

20100089306 | PORTABLE FUEL GAUGE FOR FUEL TANK - A fuel gauge is adapted to extend into a fuel tank to enclose liquid fuel in the fuel tank and to sense the level of liquid fuel in the fuel tank. The fuel gauge includes a fuel-level indicator having a needle and a buoyant float exposed to the liquid fuel in the fuel tank. The needle moves in response to changes in the level of liquid fuel in the fuel tank sensed by the buoyant float. | 04-15-2010 |
20120006251 | FLUID LEVEL INDICATOR DEVICE - A fluid level indicator device that attaches to a fluid fill nozzle of an existing fluid tank is disclosed. The device is comprised of a frame assembly that removably attaches to the fluid fill nozzle and a float assembly that is attached to the frame assembly. The first embodiment is comprised of a frame assembly that springingly and snugly fits in the interior of the fluid tank. In a second embodiment, the frame assembly is comprised of an angular hollow tube and a threaded slip that attaches the angular hollow tube to the fluid fill nozzle, and a narrow hollow tube that accommodates the float assembly. In the embodiments presented herein, the level for the float assembly visible above the top of the frame assembly indicates the relative level of the fluid in the tank. Various embodiments add indicia to the float assembly and set the relative fluid level to be the actual fluid level. | 01-12-2012 |
20130125809 | SYSTEM FOR CHECKING OIL LEVEL - An engine includes a crankcase defining an interior volume for containing lubricant, a fill apparatus including a fill passage and a cap removably coupled to the fill passage, the fill passage defining a main conduit through which the lubricant is provided to the interior volume, a visual interface including an indicator movable in response to an amount of the lubricant in the interior volume to indicate different amounts of the lubricant in the interior volume, a float configured to float on a surface of the lubricant, and a float rod coupling the float to the indicator so that movement of the float in response to changes in the amount of the lubricant in the interior volume causes movement of the indicator. | 05-23-2013 |

20150040817 | OIL LEVEL DISPLAY DEVICE OF ENGINE - An oil level display device is fitted such that a float guide accommodating a float is attached to an oil filler neck and is plugged with a float cap. To check the amount of oil, the float cap is removed and the position of the float is checked. If a sufficient amount of oil is stored, an upward force derived from oil buoyancy is larger than a downward force of the own weight of the float, from among the forces that act on the float. The float thus protrudes beyond a large-diameter portion upon removal of the float cap from the float guide. | 02-12-2015 |
