  • Patent number: 4317505
    Abstract: A hydraulic apparatus for the operation of an elevator comprises a linearly extending hydraulic cylinder and a piston slidable therein. The piston has on its downstream side a plurality of pivotally interconnected thrust members the last one of which has a slide member which is provided with a support arm with which the slide member passes through a longitudinal slot in the jacket of a linear cylinder extending in a direction parallel to the path of motion of a load receiving device and to which the load receiving device is attached. The linearly extending hydraulic cylinder and the linear cylinder are open at the lower ends and the thrust members depend downwardly at the two cylinders. The thrust members have a continuous toothing and a gear supported rotatably between the two cylinders passes through longitudinal slots in the jackets of the two cylinders and engages with the toothing.

  • Patent number: 4285501
    Abstract: An apparatus for retaining guide pulleys for load cables of a building front cable lift in a housing stationarily arranged at the top of a building, from which housing said guide pulleys are outwardly pivotable from ground. In the housing which is open at its face there are supported two beams which are outwardly pivotable horizontally and carry the guide pulleys for the load cables. The beams are retained releasably by means of an interlocking device arranged in the interior of the housing. The interlocking device is releasable by means of auxiliary cables guided on the guide pulleys, said auxiliary cables depending from an edge cutout in the base of said housing.

  • Patent number: 4264849
    Abstract: To improve the speed and simplicity of adjustment of mechanical devices, for example passenger seats and other movable members in motor vehicles, there is provided a closed-loop control system in which servo-motors adjust the final positions of the movable members. The desired configurations, i.e. the positions of the individual members of the device are stored in one or more memories for recall upon the actuation of push-buttons. The same push-buttons are used alone or in conjunction with a data storage switch to store new positions in the memory. The servo-motors are coupled to transducers which generate an electrical signal related to the position of the servo-motors and their associated movable members. Upon actuation of one of the push-buttons, the device is adjusted until the control deviation is near-zero, i.e. until the signal from the transducers conforms to the data stored in the memory.

  • Patent number: 4117903
    Abstract: To decrease the number of switches and their connections to a speed control system, only two manually operated switches are provided to, respectively, allow for "engage", "disable" and "resume" operations, the system further including a bistable circuit which is connected to one of the manually operated switches to provide the manually operated switch with a dual function.

  • Patent number: 4092853
    Abstract: The time duration of output pulses from the transducer, including wave-shaping circuits, if used, is measured and compared with respect to predetermined time limits. Two sequential pulses are measured and stored. If both pulses are shorter than a predetermined time interval, no alarm signal is generated; if the first pulse is longer than a predetermined time interval and the second also longer than a predetermined time interval, an alarm signal generation circuit, otherwise activated by the second, longer signal, is inhibited (since acceleration or deceleration of the wheel is indicated); if, however, the time duration of the second sequential pulse is longer than a predetermined time interval, but the time duration of the preceding pulse is shorter than its time duration threshold value, the malfunction signal is not inhibited, indicative of malfunction, loose contacts, or the like.
