Abstract: An operating mechanism for the window in a motorcar door and the like includes guiding devices, including at least one deflecting element, which engage a wire, cable or other elongated tension member and guide the tension member on the door in a loop-shaped path when the tension member is driven in the path alternatively in two opposite, longitudinal directions. The motion of the tension member is transmitted to the window. The tension member stretches under the longitudinal stresses exerted thereon by the drive and the window and needs to be tensioned. According to the invention, a spring in a permanently stressed condition biases the deflecting element in a direction to lengthen the path of the tension member and for thereby compensating for slack in the engaged portion of the tension member when the tension member moves in one longitudinal direction, whereby the spring reaches a partly relaxed condition.

Abstract: This invention embodies improvements in evaporative type refrigeration and space cooling units, both as to energy conservation and efficiency and economy of operation. It utilizes the new abentropic principle as set forth in my U.S. Pat. No. 4,109,470, which demonstrates that the energy of the latent heat of vapor is potential energy and need not be discarded as is done in present practice but can be converted to mechanical energy by taking advantage of the fact that the vapor pressure exuded by boiling hot condensate is the same as that of the vapor itself. The difference between this vapor pressure and that of a hard vacuum is sufficient to drive an engine. The energy necessary for the work done is extracted from the latent heat of the incoming vapor causing some of the vapor to condense at its boiling point proportionately as the work proceeds.
