Abstract: An apparatus for adjusting the assistive lifting force capacity of a height adjustable work surface. The apparatus includes a couple of plates which are mounted to a system for providing a system for adjusting the height of the work surface. The plates include a set of connection points for connecting the apparatus to a gas spring. The geometry of the holes and the positioning of the gas spring provide for a more consistent lifting force throughout a range of motion of the work surface.

Abstract: A window operating system for casement and awning windows has two actuators that are connected to be controlled by one crank to operate simultaneously. The system is modular and the crank is preferably part of a crank assembly that is a separate component from the actuators. In a further embodiment, the operating system has at least one actuator with a crank assembly to operate the actuator being located at a different location on a window frame from the actuator. With a modular system, there are numerous variations for location and number of locks and the location of the crank assembly as well as other components. The system still further describes a lock for a window operating system.
