An apparatus includes a crankshaft gear operatively coupled to an engine. An auxiliary gear is operatively coupled to the engine. An idler gear is operatively coupled to the engine, and is in meshed engagement with each of the crankshaft gear and the auxiliary gear. A ring dowel is fixedly coupled to an engine block. An idler hub has an inner surface and an outer surface. The inner surface is fixedly coupled to the ring dowel and the idler gear is rotatably coupled to the outer surface. The idler hub is eccentrically-shaped so that an idler gear centerline is offset from a ring dowel centerline so as to reduce a crankshaft backlash between the crankshaft gear and the idler gear relative to a nominal crankshaft backlash, and so as to substantially maintain an auxiliary backlash between the auxiliary gear and the idler gear relative to a nominal auxiliary backlash.

An accessory system for a gas turbine engine having a drive shaft with an axis of rotation is provided. Also provided is a bearing housing assembly for coupling the drive shaft of an accessory having a first gear to a gear associated with the accessory system. The bearing housing assembly includes a mount including an interface to be coupled to the accessory and defining a central bore, and a lock cylinder configured to receive the drive shaft. The lock cylinder is movable relative to the central bore and the drive shaft to adjust a contact pattern between the first gear of the drive shaft and the gear of the accessory system.

Articulable joints having diamond bearing surfaces engaged with metal bearing surfaces are provided herein. The articulable joints provide multiple degrees of freedom to components, such as drivelines, and bear loads in multiple directions. The articulable joints include diamond bearing surfaces slidingly engaged with opposing metal bearing surfaces that include more than trace amounts of diamond solvent-catalyst.

The laboratory device includes an elongated handle with ergonomic grips. The device has a center recess for a rod to slide or rotate. The blade head attaches at the distal end of the elongated handle. The rod has geared teeth that interact and mesh with the gears on the blade head allowing the user to manipulate the angle of the blade head via rod. The rod in the proximal position of the handle is disposed at an acute angle relative to the longitudinal axis of the handle such that the blade head and handle are positioned for insertion into and removal of a tissue culture vessel. When the rod is moved distally or rotated the blade head position is disposed perpendicularly, acute or obtusely in relationship to the longitudinal axes of the handle such that the blade head provides optimal raking opportunities for the device to collect cell colonies.
