  • Publication number: 20110262130
    Abstract: An electronic apparatus, e.g., a central signal unit for a vehicle, has a signal receiver which operates in the optical wavelength range for receiving signals of an external signal source, and an internal signal source for emitting signals which are different from signals of the external signal source, and which operates essentially in a wavelength range which is the same as or directly adjacent to the wavelength range of the external signal source. The signal receiver and the internal signal source are situated in the apparatus behind a reflective cover. The apparatus includes a suppression unit which prevents generation of interference signals at the signal receiver.

  • Patent number: 4579219
    Abstract: The disclosure relates to a conveyor chain with a plurality of chain rollers, for conveying individual items or similar material handling applications, in which respectively two chain rollers are arranged coaxially at a predetermined distance with respect to one another on a common chain pin in such a way so as to be able to rotate, whereby side bars laterally arranged on the chain pins are used to connect respective sequentially arranged chain rollers, and the individual chain components are adapted to form an endless chain. The chain also includes conveyor rollers on those chain pins which are respectively arranged between two adjacent chain rollers of the chain, and these conveyor rollers have a larger diameter than the chain rollers. Recess-like depressions which are formed between two adjacent conveyor rollers in the chain are filled by bridge-forming space members which are secured on the respective chain pins, or on sleeves.
