A system for distributing semisolid lubricant, including a semisolid lubricant tank and a high pressure pumping system that intermittently feeds, during a lubrication cycle, at least one first duct, the at least one first duct feeding a plurality of distributors adapted to sort the semisolid lubricant to a plurality of users; a controlled suction/delivery device, fluidly associated with the first duct, for controlled suction/delivery of a part of the semisolid lubricant conveyed by the first duct. The controlled suction/delivery device configured to suck a volume of semisolid lubricant from the first duct during a step of inactivity of the pumping system on the first duct, and to introduce the previously suctioned semisolid lubricant in the first duct during a step of activity of the pumping system on the first duct.

A self-cooling fluid storage container includes a reservoir to store a fluid at a level that allows for an air space above the fluid. The fluid enters the reservoir. A fluid conduit receives the fluid at a fluid input opening to an internal fluid conduit that extends upward towards the air space. A heat exchanger portion extends sufficiently near the air space to provide a thermal exchange with the air space. The heat exchanger receives fluid to provide a cooling of the air space. The internal fluid conduit continues extending downward from the air space to a fluid output opening for distribution to a system that uses the fluid.

A system and method for efficiently measuring the fluid level in a container having a non-uniform cross sectional area is described. The measuring device may be immersed in the fluid and have a float slidable along a structure having the capability to sense an aspect of the location of the float. Since the accuracy requirements in measuring the fluid level may be more important for the higher levels and the lower levels than the intermediate quantities, the sensor may likewise be configured to provide more accurate measurements near the upper and lower fill levels. The position of a float may be determined by capacitive optical or magnetic sensing techniques and the sensed position translated into engineering units for output by a calibration table.

A device for lubricating a hinge includes a housing, a first elongated opening, and an absorption element. The first elongated opening allows the housing to be placed over at least a portion of a hinge. The first absorption element entirely disposed within the housing such that the first absorption element is positioned to engage a portion of a hinge when the housing is placed over the portion of the hinge.

An automatic lubricator for lubricating an object is provided. The lubricator includes a housing with a coupling section configured to couple with a lubricant container containing a lubricant, wherein the lubricant container comprises a rotatable shaft with a piston to dispense the lubricant from an output of the lubricant container. The lubricator further includes an electric motor configured to drive the rotatable shaft of the lubricant container during at least one lubrication action, such that at least a part of the lubricant is dispensable from the lubricant container during the at least one lubrication action. The lubricator further includes at least one sensor arranged within the housing and configured to provide a sensor signal indicative of a distance between the at least one sensor and the piston of the lubricant container, and a control circuitry configured to determine, based on the sensor signal of the at least one sensor, at least one lubrication parameter indicative of the at least one lubrication action
