Latest Patents
One of Karl Sperber's latest patents is the "Film unit assembly." This invention involves a photographic film unit that includes a film disk carried on a hub. A mass of firm material is deposited between the disk and the hub, allowing the mass to determine the relative film-to-hub alignment accurately. The hub fits loosely in a central film-disk aperture initially. The thermo-plastic material is melted ultrasonically to flow between the disk and the hub, eliminating looseness and maintaining accurate alignment. This design also ensures that foreign matter, such as processing fluids, is excluded.
Another notable patent is the "Turn-on method and apparatus for ultrasonic operations." This invention features an ultrasonic method and apparatus with improved turn-on capabilities. Low-level power is supplied to an unloaded transducer to initiate operation at a desired frequency. High-level power is then provided for performing ultrasonic operations while loaded. The high-level power is stopped, and the low-level power is maintained, reduced, or stopped before the load is removed.
