Abstract: An optical sight is provided and includes a housing having a first bearing surface integrally formed therewith and a relay assembly having at least one optical element, a main tube, and a track tube having at least one track. The track tube is selectively rotatable relative to and about the main tube to adjust an axial position of the at least one optical element within the main tube along an axis that is substantially parallel to a longitudinal axis of the main tube. The main tube includes a spherical surface that is in contact with the first bearing surface of the housing to define a pivot point of the main tube within the housing.

Abstract: An adjustment turret for an optical sight is provided and may include a housing and an adjustment member rotatably supported by the housing and operable to adjust a characteristic of the optical sight when moved relative to the housing. The adjustment turret may additionally include a cap extending from the housing and movable between an engaged state fixing the cap for rotation with the adjustment member and a disengaged state permitting relative rotation between the cap and the adjustment member. The cap may be moveable from the disengaged state to the engaged state in a direction away from the housing.

Abstract: A method and apparatus for recycling water based workpart cleaning fluid of the type used to wash workparts (B) free of soils, such as emulsified and non-emulsified cutting oils and lubricants, particulate matter and other hydrophobic fluids. A parts washer (12) is provided for cleaning workparts (B) contaminated with soils. The contaminated cleaning fluid is discharged from the parts washer (12) in a slip stream and directed to a process tank (22). The contaminated cleaning fluid is pumped from the process tank (22) to a prefilter (28) where large particles are screened. The cleaning fluid is then directed to regenerated cellulose membrane filters (34) where the water based cleaning fluid and the hydrophilic water soluble substances in the base, i.e., the detergents, are imbibed through the membrane (34) as permeate while the soils pass as retentate. The permeate is returned to the parts washer (12), whereas the retentate is directed back to the process tank (22).

Abstract: Disclosed is an apparatus for providing generally lateral or rearward vision at a plurality of selectable angles. This apparatus is electro-mechanically rotatable and may be remotely actuated. The apparatus includes a support member used to support the apparatus and connect it to whatever it is to be used with. Also included is a rearview structure having a housing, a mirror, a mechanism for rotatably connecting the mirror to the housing, and another mechanism for symmetrically rotating the mirror through the various angles. The apparatus also includes a mechanism which can be remotely operated to actuate the rotating mechanism of the rearview structure.
