Abstract: A method controls a set of semi-active actuators arranged in an elevator system represented with a model of a virtual elevator system having a single virtual semi-active actuator arranged to compensate a virtual disturbance proportional to a sum of disturbances from the set of disturbances. The method determines the virtual disturbance during an operation of the elevator car using a motion profile of position of the elevator car during the operation and a disturbance profile of the virtual disturbance, and determines amplitude of a virtual force of the virtual semi-active actuator using the model and the virtual disturbance. A gain of a controller for controlling the set of semi-active actuators is adjusted based on the amplitude of the virtual force and a reference force of the virtual semi-active actuator.

During extended periods of non-use, the elevator car is positioned such that the flange engages the cam and the loading on the contact surface of the roller is minimized or eliminated.
Abstract: Rail learning is combined with feedback in a control for improving ride quality in an elevator. For example, a pre-stored signal indicative of a horizontal deviation of the rail's surface from a vertical reference is retrieved and used along with a sensed signal indicative of a horizontal position (or other parameter indicative of a disturbance of the elevator) relative to the rail's surface (or a reference) for controlling an actuable horizontal suspension for reducing horizontal disturbances of the elevator while guiding an elevator vertically in a hoistway along a rail. As another example, a sensed force signal is averaged over a plurality of trips under differing load conditions and the average is pre-stored for retrieval at various vertical points in the hoistway and may be used, in combination with a feedback loop, to predict horizontal forces about to act on the car.
Abstract: This apparatus relates to a safety mechanism for a rail system having tracks adapted to be moved in an out of alignment for the transfer of an object from one track to the other. More specifically, the apparatus relates to a mechanism which prevents the accidental movement of an object off the end of one track unless the tracks are in substantial alignment.
Abstract: Left side panels and right side panel are produced in a left side panel production line and a right side panel production line, respectively By vertical lifters, each left side panel and each right side panel are lifted at the delivery stations and then transferred to runners at work transfer positions. The runner with the left side panel held thereon travels along a rail while the runner with the right side panel held thereon travels along a rail. Both runners are stopped at a standby position and then conveyed to a runner transfer position simultaneously. The runners with the left and right side panels held thereon, respectively, are loaded on the traverser and then conveyed to a drop lifter arranged above a main body assembly line. The left and right side panels are transferred to the drop lifter. The drop lifter then descends and feeds the left and right side panels simultaneously on opposite sides of a floor panel in the main body assembly line.

Abstract: A variable height workstation includes a trolley delivery apparatus for moving a rail section from a gap formed in a subsidiary loop rail to a workstation located remotely from the loop. A pivotal cam moves with the rail section and arrests travel of a trolley on the movable rail section so that rail section may be moved toward the workstation while carrying the trolley. As the rail section moves upwardly toward the gap formed in the subsidiary loop, the cam rotates and accelerates the trolley off the rail section. The trolley delivery apparatus is employed in a subsidiary loop system whereby a first escapement device is located upstream of it to advance selected one of the diverted trolleys onto the moveable rail section.
