A turbomolecular pump has a housing, a rotor shaft supported by a plurality of bearings for rotation relative to the housing about an axis of rotation, a deflector, a lubricant supply system and a lubricant transfer device provided on the rotor shaft. The bearings include a rolling bearing that receives lubricant from the lubricant supply system to via the lubricant transfer device. The rolling bearing is disposed intermediate the lubricant transfer device and the deflector and the deflector is configured to deflect lubricant that passes through the rolling bearing outwardly with respect to the rotor shaft.

A lubricant supply device for a linear guide apparatus is configured to include an end cap 5, and a container 7 retaining lubricant and disposed adjacent to the end cap 5. The end cap 5 is formed with a through-hole 16 extending toward the container 7 from a direction change path 5a. The container 7 is formed with an aperture communicating with the through-hole 16 of the end cap 5. The lubricant is supplied into the direction change path 5a via the aperture of the container 7 and the through-hole 16 of the end cap 5. The slider can be thereby lubricated while preventing damage to a rolling element and the direction change path of the end cap.

Systems and methods provided herein concern a fluid delivery system for use with medical devices and, more specifically, for activating surface coatings of medical devices prior to use in medical procedures. The fluid delivery system comprises one or more sheets of biocompatible wicking material that is attached to a reservoir. Sealed within the reservoir is a fluid, such as physiologic saline or other appropriate hydrating solution. In addition, the reservoir comprises at least one outlet, such as a frangible seal, that can be selectively breached prior to use by applying pressure to the reservoir, e.g., by squeezing or twisting the reservoir. Breaching the frangible seal thus releases the fluid onto the wicking material, which, in turn, serves to wet the medical device and consequently activate the surface coating.

A fluid application device for mechanical fasteners such as rivets, screws, bolts, and similar fasteners, and a robot end effector including such a device as well as a robot being equipped therewith. The fluid application device includes a fluid application element having a curved application surface, wherein the curved application surface includes a channel configured to receive a fluid. A brush is arranged at the curved application surface such that the fluid is able to wet the brush elements. The device further includes a gripping device configured to push a mechanical fastener against the wetted brush elements.

A twin-shaft pump comprising: two shafts configured to rotate in synchronisation, each of the shafts comprising a gear mounted thereon, the gears each comprising gear wheels, the gear wheels being configured to intermesh to provide the synchronised rotation; an oil reservoir comprising a porous material, the reservoir being configured when supplied with oil to retain the oil within the porous material; and at least one wick extending from the oil reservoir towards a first of the two shafts and operable to supply oil by capillary action from the porous material along the wick to lubricate the gears.
