Abstract: An ice-making machine has a substantially vertical ice-forming mold for freezing cubes of ice, a water distributor for distributing water so as to cascade over a front surface of said ice-forming mold and a hinged water curtain with a bottom edge for directing said cascading water into a sump, with the hinge allowing the water curtain to swing out of the way so that ice cubes harvested from the mold may fall past the sump and into an ice collecting bin. The water curtain has an inside surface adjacent to a front surface of the ice-forming mold configured such that as a slab of ice cubes is released from the mold during a harvest cycle, the front of the slab of ice contacts said inside surface and forces the water curtain to open to a point where the bottom of the falling slab of ice cubes will not contact the bottom edge of the water curtain.

Abstract: A spray end effector for spray painting internal cavities of complex shapes comprising a first elongated arm having an inboard end with attachment means for coupling to a robot and also having an outboard end; a second elongated arm having an inboard end fixedly coupled to the outboard end of the first arm and also having an outboard end; a third elongated arm having an inboard end pivotally coupled to the outboard end of the second arm and also having an outboard end with a rod for supporting a spray gun rotationally coupled with respect thereto; a first air motor having a shaft rotatable about its axis located within the second arm for rotating a jack screw and longitudinally driving a threaded housing to effect the pivotal movement of the third arm with respect to the second arm; a second air motor having a shaft rotatable about its axis located within the third arm for rotating a speed reducer to effect the rotational movement of the rod with respect to the third arm; and means to effect the proper rotati
