Abstract: Methods and devices for sorting cottonseeds. Methods include the use of an optical sorter to sort cottonseed by color. Additionally, methods include sorting cottonseed using a gravity table to collect high-density seed (“accepts”) and mid-density seed (“middlings”), followed by sorting the mid-density, and optionally, the high-density seed using an optical sorter to collect dark cottonseed, thereby providing high-quality cottonseed for packaging. Devices and systems comprising one or more gravity tables and one or more optical sorters are provided.

Abstract: The present invention discloses a method and apparatus for fully automated iterative polymer synthesis at a large scale.

Abstract: A contact piece for a high-voltage circuit breaker includes at least a contact pin and a contact carrier. The contact carrier is configured to mechanically fasten the contact pin in the high-voltage circuit breaker. The contact pin includes a contact shaft. The contact carrier and the contact shaft are formed as a monolithic contact element. A method for producing a contact piece is also provided.

Abstract: A gear unit housing for a gear unit includes a two-sided control lever for moving two switching contacts of a circuit breaker in opposite directions. The gear unit housing includes a housing cassette having a housing base and a cover plate detachably connected to the housing cassette by screw connections and lying opposite to the housing base. A bearing shaft for mounting the control lever for rotation about the bearing shaft is connected to the housing cassette and to the cover plate and extends between the housing base and the cover plate. At least one stud element form-lockingly connects the housing cassette and the cover plate. A gear unit having the gear unit housing is also provided.

Abstract: Trim layers that are configured to adjust one or more operating parameters for surface acoustic wave (SAW) devices are disclosed. A SAW device may include an interdigital transducer (IDT) and a piezoelectric material that are configured to generate an acoustic wave and a trim layer that has an acoustic velocity and a density that correspond to a velocity of the acoustic wave. In this manner, the trim layer may be configured to adjust an electromechanical coupling of the SAW device without significantly impacting a resonance frequency of the SAW device. The SAW device may also include an additional trim layer that is configured to adjust a coupling percentage and the resonance frequency of the SAW device. A SAW device may include a trim layer that is configured to adjust certain operating parameters by greater amounts than other operating parameters.
