Abstract: A constant velocity joint (10) is provided specifically for connecting a yoke (14) to a mast (12) in a helicopter and more generally (200) for interconnecting a first shaft (202) to a second shaft (204) for bidirectional drive. The constant velocity joint employs a carrier (40, 218) which is formed with a series of apertures for receiving elastomeric bearing assemblies (42, 80, 220). The elastomeric bearing assemblies are provided with a spherical elastomeric bearing (60) and a cylindrical elastomeric bearing (48). Certain of the elastomeric bearing assemblies connect the carrier to one of the rotating members while the remaining elastomeric bearing assemblies connect the other rotating member to the carrier. The axis of symmetry (67) of the carrier always bisects the angle of misalignment between the two rotating shafts or members to assure that a constant velocity joint is achieved.

Abstract: A method of folding the main rotor blades of a helicopter for storage in which blade supports are removably attached to the nose and tail of the fuselage of the helicopter. A first and second main rotor blades then are aligned with the longitudinal axis running from the forward blade support to the aft blade support. The first and second blades are placed upon, and restrained from rotation in, the blade supports. Then the first and second blades are permitted to fold about the rotor assembly of the helicopter by releasing a locking member of each blade. The first and second blades are folded by rotating the main rotor assembly while restraining from rotation the first and second blades in the forward and aft blades supports, respectively. After the rotor assembly is rotated through approximately 90 degrees, a third and fourth of the rotor blades are aligned with the longitudinal axis running through the forward and aft blade supports and the first and second blades are fully folded.

Abstract: There is disclosed an improved adjusting mechanism for an articulated headlamp construction or the like. The adjusting mechanism is comprised of a minimum number of parts, namely a housing, a scroll member and an adjusting rack member. The scroll member provides the input member for the mechanism and upon rotation thereof rotative movement thereof is transformed into transitory movement of the rack member pursuant to a spiral or scroll projection that is engaged with teeth on the adjusting rack member. The transitory movement of the adjusting rack member will correspondingly produce pivotal movement of the articulated headlamp component. If desired, the adjusting rack member may be curved so that the movement of the end thereof affixed to the headlamp will closely approximate the pivotal movement of the headlamp component.
