Abstract: A counterbalance mechanism for height adjustable computer equipment supports and the like that includes a drive shaft mounted on an associated support for axial rotation. The drive shaft is operably connected with a worksurface to facilitate vertical adjustment of the same within a predetermined range. The counterbalance mechanism has a first energy storage device operably connected between the support and the drive shaft, which applies a first axial torque to the drive shaft in a first rotational direction. The first energy storage device is configured such that the first axial torque diminishes at a predetermined rate as the drive shaft rotates in the first rotational direction. A second energy storage device is operably connected between the support and the drive shaft, and applies a second axial torque to the drive shaft in a second rotational direction, opposite to the first rotational direction, thereby defining a resultant counterbalance force which facilitates vertical adjustment of the worksurface.

Abstract: The shutter blades of a scanning blade shutter and the movable element of an adjustable focus lens in a single lens reflex camera are actuated by a single or common drive. The scanning blade shutter is coupled to the common drive by a rotatably mounted beam member. The movable lens element is also coupled to the common drive through a drive link assembly and the same beam member. Actuation of the beam member by the common drive simultaneously moves the shutter blades in the single lens reflex camera toward their closed positions and moves the lens element coupled thereto by a drive link assembly toward a rangefinder-determined lens focal position. A solenoid coupled to a drive link in the drive link assembly and responsive to rangefinder-derived object distance signals actuates the drive link to uncouple the movable lens element from the beam member when the movable lens element has been moved to a particular focal position determined by the rangefinder.

Abstract: A viewfinder assembly fabricated virtually exclusively of injection molded plastics includes a housing, four lens groups, four mirrors for folding the optical path and providing for proper image orientation, and mirror retainers. All of the components are structured to snap-fit together such that the optical components of the assembly are automatically nominally positioned when placed connected in the housing. Adjustment features for lens tilt and framing are also provided and, as well, means for displaying visual information in the viewfinder field.

Abstract: A folding camera including first, second and third housings pivotally interconnected for movement between an operative extended position and a folded position, and a source of artificial illumination, e.g., a strobe, which automatically moves into an operative position as the housings move into the fully extended position. A manually operable lever is pivotally coupled to the third housing and coupled to the strobe such that the rotation of the lever from a first position to a second position is effective to initially move the strobe into a retracted position and thereafter continued application of force to the lever causes rotation of the third and second housings into a folded position atop the first housing.

Abstract: A wire terminal connection by which a leaf-like contact may be electrically joined with a stripped end portion of a wire lead retained by a non-conductive mounting structure for the contact. As disclosed, the connection is embodied in a battery contact assembly of a photographic camera in which all electrical components are assembled as an interior module to be pretested for operational reliability prior to assembly of the module with an exterior housing. The retention of the wire leads by the non-conductive contact mounting facilitates module assembly and pretesting prior to applying the battery contacts.
