  • Patent number: 11662245
    Abstract: A payload measurement system can be used to measure the payload added to a machine supported on a plurality of walking beams. A plurality of load cell sensors is mounted to the walking beams in locations where, when the walking beam bends, the sensors are placed under load. The load cell sensors include a symmetrical strain bar having first and second mounting ends connected by a connecting span, wherein the end thickness is greater than the span thickness of the connecting span. The connecting span is disposed between and spaced apart from an upper plane and a lower plane with which the surfaces of the mounting ends are aligned.

  • Patent number: 11345569
    Abstract: A monitoring system for controlling self-testing of a traction elevator includes a self-testing process module in communication with a three-phase AC back-up battery power supply. The self-testing process module includes a processor configured to initiate and control a series of steps for performing measurements of the three-phase AC back-up battery power supply, including measurements of the battery supply during a simulated emergency situation (“rescue/evacuation”). The processor is programmed to initiate testing on a defined schedule and transmit test results to a maintenance system (including remotely-located systems) on a routine basis. The monitoring system also includes a display unit providing visual information regarding the status of self-testing processes and their results and a communications unit for transmitting test results to a remote maintenance controller.

  • Patent number: 10636225
    Abstract: A method for operating a machine adapted to transport a load during a work cycle is disclosed. The method includes determining a first stationary state of the machine, and causing sensors to start transmission of first signals. The first stationary state corresponds to a first segment of the work cycle, and the first signals indicate a weight of the load during the first segment. Further, the method includes determining a moving state of the machine corresponding to a second segment of the work cycle, and causing the sensors to terminate transmission of the first signals. Furthermore, the method includes determining a second stationary state of the machine, and causing the sensors to start transmission of second signals. The second stationary state corresponds to a third segment of the work cycle, and the second signals indicate a weight of the load during the third segment.

  • Patent number: 10432020
    Abstract: An emergency power supply for a traction elevator system utilizes a microprocessor-based control arrangement with pulse-width modulator technology to create an efficient, cost-effective back-up power system for a traction elevator. The microprocessor-based control arrangement is used to sense a phase irregularity in the power supply. Upon sensing the phase irregularity, the microprocessor-based control arrangement disconnects the elevator system from the main power source and then generates a control signal to initiate the supply of back-up power. Once the elevator electrical system has been stabilized, the elevator control system will sense that recovery has occurred and will then provide an appropriate speed and direction command to the traction motor drive system.

  • Patent number: 7275622
    Abstract: A back-up power system for a traction elevator includes a power sensing device to sense a power loss or irregularity of the normal control power. An inverter timing system is connected to the power loss sensing device. The inverter timing system receives a power sensing signal from the power sensing device. A back-up power generating system communicates with the inverter timing system and generates an output to provide back-up power to the elevator system.

  • Patent number: 5580103
    Abstract: O-ringless coupling device including a pair of junction elements for attachment to the ends of flow lines to be connected and a coupling nut. One of the elements is provided with a coupling face having at least one annular groove formed therein circumscribing the fluid passageway. The sidewalls of the groove or grooves are angularly inclined relative to each other so that the width of the groove decreases with depth. The opposing face of the second junction element is provided with an annular rib, the transverse thickness of which is adapted to mate with the opposing groove of the first element such that when the nut is used to draw the two junction elements together, the rib mates with the groove and forms a seal therebetween. Preferably, the distal extremity of the rib is narrower than the proximal extremity and is of a dimension such that the walls of the annular rib mate with the walls of the annular groove such that coupling pressure wedges them together forming pressure seals at the engaging sidewalls.
