  • Auxiliary device for displacing a payload receptacle of an elevator
    Patent number: 6598709
    Abstract: An auxiliary device for displacing a payload receptacle, which stands outside a station, into one of the stations. The auxiliary device includes a temporarily activatable brake release device for releasing the braking device and an auxiliary drive device for displacing the payload receptacle when the brake release device is activated. The brake release device and the auxiliary drive device are arranged in the uppermost region of the elevator shaft and are actuable by way of a crank rod linkage. The crank rod linkage includes a lower actuating end, which can be brought from a rest setting into a working setting. The crank rod linkage is coupled with a rod linkage extension, the vertical effective length of which corresponds with at least the vertical spacing of the walk areas of two adjacent stations.

  • Method of deriving a frequency of a pulse signal from alternate sources and method of calibrating same
    Patent number: 6590376
    Abstract: A method derives a frequency of a pulse signal from a line frequency. The method includes measuring a period of a line frequency pulse signal having the line frequency using a measured frequency derived from an oscillator frequency. The method further includes determining if the period of the line frequency pulse signal is within a predetermined tolerance limit. The line frequency is used to derive the frequency of the pulse signal when the period is determined to be within the predetermined tolerance limit, and the oscillator frequency is used to derive the frequency of the pulse signal when the period is determined to be outside the predetermined tolerance limit.

  • Auxiliary device for displacing a payload receptacle of an elevator and device for monitoring the position and the movement of a cage in a shaft of an elevator
    Patent number: 6427809
    Abstract: The auxiliary device is needed when the elevator stands in the elevator shaft outside a station. The auxiliary device includes an auxiliary drive device for the payload receptacle. For sight-free observation of the auxiliary device there is arranged an image transmission device, which includes a sensor, a display device and a transfer path. The sensor serves for detection of images which illustrate a drive pulley coupled with the auxiliary drive device. The display device serves for visualization of the images detected by the sensor, and the transfer path serves for transmission of the images detected by the sensor to the display device.
