Abstract: An earplug dispensing mechanism defining a longitudinal axis, and including separator and index assemblies. The separator assembly includes a platform, a guide wall and bores. The guide wall projects from the platform to define a well for receiving earplugs. The bores each extend from an entrance opening to an exit opening. The index assembly is rotatably coupled to the separator assembly, and includes a handle, a plate, and a mixing body. The plate is connected to the handle and defines a dispensing aperture. The mixing body has an upper end, a lower end, and an exterior surface defined by a cone portion and a paddle portion. The cone portion tapers in diameter. The paddle portion projects radially from the cone portion at the lower end. The exterior surface is asymmetrical to encourage earplug mixing within the well, and to impede earplugs from entering a bore open to the dispensing aperture.

Abstract: A manually operable dispenser for dispensing disposable earplugs. The dispenser includes a housing, index body, and plate. The housing forms an opening for receiving earplugs from a container. The index body includes a handle, hub, guide cone and shield. The hub forms opposing major faces and a plurality of circumferentially arranged bores. The guide cone projects from the upper major face, tapering in diameter to a leading end. A base of the shield is disposed above the leading end opposite the upper major face. A wall of the shield projects radially outwardly to an edge having a diameter greater than a diameter of the leading end. The shield and the handle are rotationally affixed. The hub is rotatably mounted within the opening. The plate is connected to the housing and forms a dispensing aperture. A manually-applied rotational force at the handle selectively aligns individual ones of the bores with the dispensing aperture.

Abstract: Voltage sensor (1) comprising a voltage divider (40) for sensing an AC voltage of a HV/MV power conductor (10). For adjusting the common overall impedance of the low-voltage portion of the voltage divider towards a desired impedance, the low-voltage portion (60) comprises one or more low-voltage impedance elements (110), a plurality of adjustment impedance elements (80) and a plurality of switches. In its connect state, each switch electrically connects an adjustment impedance element in parallel to at least one of the one or more low-voltage impedance elements (110). The overall impedance of the high-voltage portion (50) and the overall impedance of the low-voltage portion (60) of the voltage divider (40) are adapted such that, by bringing one or more of the switches (90) into their connect state, the voltage divider (40) has, for an AC voltage of between 5 and 25 kV phase-to-ground and a frequency of between 40 and 70 Hertz, a dividing ratio of 3077, of 6154, of 6769 or of 10 000.

Abstract: A manually operable dispenser for dispensing disposable earplugs. The dispenser includes a housing, an index body, and a plate. The housing forms an opening for receiving earplugs from a container. The index body includes a handle and a hub. The hub forms an upper major face, a lower major face, and a plurality of circumferentially arranged bores. Each of the bores is open to the major faces and is defined by a wall surface extending through a thickness of the hub. At least a portion of the wall surface of each of the bores has an anti-bonding construction. The hub is rotatably mounted within the housing. The plate is connected to the housing, and forms a dispensing aperture. A manually-applied rotational force at the handle selectively aligns respective ones of the bores with the dispensing aperture. The anti-bonding construction promotes sliding, low friction interface with individual earplugs.

Abstract: An earplug dispensing mechanism defining a longitudinal axis, and including a separator assembly and an index assembly. The separator assembly includes a platform, a guide wall and bores. The guide wall projects from the platform to define a well for receiving earplugs from a container. Each bore is open to the well at an entrance opening. The guide wall forms a close, compound curve shape in a plane perpendicular to the longitudinal axis and surrounding the entrance openings. The index assembly is rotatably coupled to the separator assembly, and includes a handle, a plate, and a mixing body. The plate is connected to the handle and defines a dispensing aperture. The mixing body is connected to the plate opposite the handle. Rotation of the handle selectively aligns the dispensing aperture with individual ones of the bores, with the guide wall shape funneling earplugs in the well toward the bores.
