  • Patent number: 9382100
    Abstract: The invention provides a levelling system for the chair of a stairlift, a characteristic feature of the system being the provision of a safety back-up or locking mechanism that will lock the position of the chair in the event of failure within the levelling drive. This locking mechanism preferably includes a locking wheel that is in partial mesh with a geared wheel forming part of the levelling drive. In the event of failure within the drive the locking wheel meshes to lock the position of the chair.
    Type: Grant

  • Patent number: 4594533
    Abstract: The present invention concerns a device for analyzing chemical substances and monitoring chemical reactions in which cuvettes on a turntable are rapidly scanned by light at test and reference wavelengths and intensity of the light after passage through the cuvettes monitored by a photodetector. The output of the photodetector is logically processed so that measurements can be made of the varying optical densities in the samples scanned.
