  • Patent number: 5556466
    Abstract: In order to improve a coating plant for workpieces, in particular for vehicle bodies, comprising a coat application section, a coat drier section following the application section and comprising a drier booth arranged at a higher level in relation to the coat application section, a skid conveyor on the inlet side passing through the coat application section, the skid conveyor moving workpieces mounted on skid frames through the coat application section at a process feeding speed for the application of the coating, and a drier conveying device following the skid conveyor and conveying the skid frames with the coated workpieces mounted thereon through the coat drier section, such that this is simpler in its construction than the known coating plants it is suggested that the drier conveying device be a drier conveyor following the skid conveyor and moving the skid frames at the process feeding speed along a skid frame path through the coat drier section, that the drier conveyor extend beneath the skid frame path

  • Patent number: 4247930
    Abstract: An electronic timepiece, in particular, a battery-operated quartz wristwatch including a housing in which there is arranged an analog display mechanism as well as a liquid crystal display unit which facilitate a display of different time magnitudes. The display surface of the liquid crystal display is practically as large as the watch dial surface of the analog display mechanism. The liquid crystal display unit is arranged in the housing of the watch in front of so as to superimpose the analog display mechanism. Preferably, the liquid crystal display is transparent and constructed as a replacement for the usual watch crystal as the generally viewed protective cover for the watch housing.
