  • Patent number: 11506524
    Abstract: The present invention provides an elevator encoder diagnostic system and an elevator encoder diagnostic method by which input and output ports are kept from being occupied, functional restriction is suppressed, and abnormalities and malfunctions occurring in encoders provided in a dual-system can be detected. The elevator encoder diagnostic system according to the present invention includes a first encoder 16a and a second encoder 16b that are provided on a rotary portion of the elevator, a first diagnostic unit 21a connected to the first encoder, and a second diagnostic unit 21b connected to the second encoder, a first determination unit 23a and a second determination unit 23b that detect differences between encoder rotation amounts of the respective encoder systems and rotation detection signals of the other encoder systems, and, if a difference therebetween exceeds a predetermined threshold, determines that an abnormality has occurred.

  • Patent number: 4888936
    Abstract: A process and apparatus for continuously producing bottled beverages and closing bottles with caps, each bottle having an externally threaded mouth and having been charged with a liquid product for drinking, the apparatus includes a timing screw for advancing bottles continuously at fixed spatial intervals, each bottle having an externally threaded mouth and having been charged with a liquid product for drinking. An inlet star wheel having a plurality of recesses at the periphery thereof at fixed spatial intervals is provided. The recesses receive bottles with externally threaded mouths that have been conveyed by the timing screw. A cap release applies caps onto the threaded mouths of bottles. A nozzle ejects a stream of a non-oxidizing gas into bottles with the nozzle being situated immediately ahead of the cap release. A capper having a plurality of recesses at the periphery thereof at fixed spatial intervals is provided.
