Abstract: An agricultural device for soil processing with two sets of working rollers comprises a supporting frame, which comprises a central part, a left wing and a right wing. The left and right wings are rotatably attached to the central part. At least two rows of working units are attached to the supporting frame. The working units are arranged in regular distances in every row. A left set of rollers is attached to the left wing and a right set of rollers is attached to the right wing. The sets of rollers are divided into front rollers and rear rollers and provided with attachments and discs. The discs on the sets are located between these attachments. The number of discs of rear rollers differs exactly by one disc from the number of discs of front rollers. The distances between individual discs are the same along the whole width of the agricultural device. The discs of front rollers are located in the same plane as the working units.

Abstract: Disclosed embodiments are directed at geospatial location-specific risk pricing of a peril. The disclosed embodiments can facilitate pricing insurance premiums for various types of perils such as flood, wildfire, volcano, etc. Based on collecting location-specific data of one or more characteristics of the Earth's surface, specific risk scores for a specific location can be derived. The specific risk scores can be processed to determine a premium for the specific location.

Abstract: A spark plug with improved wear resistance includes an outer conductive housing, a ceramic insulator positioned within the housing, and a central electrode inside the insulator. One or more ring-shaped auxiliary electrodes are positioned on the ceramic insulator between the central electrode and the outer conductive housing. The one or more ring-shaped auxiliary electrodes have a central portion and peripheral edges which are thickened with respect to the central portion. The spark plug provides a spark gap between the central electrode and the auxiliary electrode and between the auxiliary electrode and the conductive housing.
