A lubricant sheet comprises a blank of material folded along a fold line into a folded configuration to form a lubricant containment pocket; a lubricant in the lubricant containment pocket; and a primary barrier for the lubricant. The primary barrier extends around and seals the lubricant containment pocket to hold the lubricant in the lubricant containment pocket. The blank of material includes a fold of material along the fold line forming a secondary barrier for the lubricant. When the lubricant in the lubricant containment pocket is being compressed during shredding of the lubricant sheet so as to cause some of the lubricant to be released through the primary barrier, the secondary barrier is configured to deflect the released lubricant that is released towards the secondary barrier.

A machine lubrication system includes a bellows-type container filled with lubricant that connects to a support base of a pump of the lubrication system. The container includes a neck extending from a convex bottom surface of the container. The support base includes a concave mounting surface and a passageway in communication with an inlet of the pump. The neck sealingly attaches the container to the passageway with the bottom surface of the container on the mounting surface the support base.

A fluid catchment assembly for capturing fluids leaking from an internal combustion engine includes an oil pan structured to fit over a factory installed oil pan of an internal combustion engine thereby facilitating the oil pan to capture fluids that leak from the internal combustion engine. A sight glass is fluidly integrated into the oil pan thereby facilitating the sight glass to visually display a fluid level in the oil pan. A plug is insertable into the drain for closing the drain and a pair of attachments is each attached between the internal combustion engine and the oil pan. Each of the attachments releasably retains the oil pan on the internal combustion engine.

A linear transmission device with capability of real-time monitoring of an amount of a lubricant includes a long shaft, a moving part, a lubricating device and a detecting module. The lubricating device includes a shell and an oil containing unit. The shell is formed with a first accommodating space. The oil containing unit is disposed in the first accommodating space and configured to provide the lubricant to an outer surface of the long shaft. The detecting module includes a temperature sensing unit and a control unit. The temperature sensing unit is configured to detect a current temperature of the oil containing unit. The control unit is connected with the temperature sensing unit and configured to: receive the current temperature; calculate a remaining amount of the lubricant of the oil containing unit based on the current temperature and an oil releasing model; and output the remaining amount.

The invention relates to a method of manufacturing at least one tank with a shell, in particular a turbojet engine oil tank. The method comprises the following stages: (a) definition of different shell sections (58) for each tank, whereof a first shell section (58) has a recess (60) and a second shell section (58) a boss (62); (b) production of the shell sections (58) by additive manufacturing in which the boss (62) on the second shell section is produced in the recess (60) in the first shell section; then (c) welding of the sections (60) one to the other.

The invention relates to an apparatus and a method for dosing a lubricant into compressed-air supplied to an air motor. According to the invention, the lubricant is stored in a lubricant storage space (17) from which the lubricant is led, along a lubricant line (19), to a doser (20). The doser (20) doses the lubricant into a dosing line and, therefrom, into a compressed-air line (12) extending to the air motor. The amount of lubricant contained in the storage space (17) is controlled by changing the volume of the storage space (17) by directing the pressure of the compressed-air line (12) to the lubricant storage space (17).
