Abstract: A bandsaw blade, including a main tooth group formed by nine sawteeth arranged in sequence, including three sub-tooth groups including a first sawtooth (1,4,7) of straight tooth, a second sawtooth (2,5,8) of left set tooth and a third sawtooth (3,6,9) of right set tooth. Each of sawteeth (1) and (4)-(6) has chamfers on two sides. Sawtooth (1) has a first height, sawtooth (4) has a second height and sawtooth (7) has a third height. Sawteeth (5) and (6) have the same fourth height. Sawteeth (2), (3), (8) and (9) have the same fifth height. The first through fifth heights are sequentially decreased. A top plane width of sawtooth (4) is larger than that of sawtooth (1). A top plane width of sawtooth (7) is larger than that of sawtooth (4). By using the bandsaw blade, more chips can be produced to reduce total cutting force and improve cutting efficiency.

Abstract: A system and method for distribution of digital content and goods includes means for rewarding multiple levels of participants involved in the recommendation/sales process. Distribution may be direct through platform-generated commerce and/or indirect through recommendations on external social media sites, communications platforms, blogs and other social and commerce sites. Multiple levels of users of the system may be compensated for participating in sales of content based on their activity and hierarchy within user networks related to the sale.

Abstract: Product Data Management systems, methods, and mediums. A method includes receiving a lock request for data of a specified type. The method includes processing the lock request in response to the lock request, including locking the data of the specified type for a plurality of data objects in response to the lock request. The method includes receiving at least one change to data of the specified type for at least one of the plurality of data objects, The method includes updating and saving the at least one of the plurality of objects according to the received change by changing the data of the specified type.

Abstract: A bandsaw blade includes a strip and teeth projecting therefrom, which teeth are arranged in recurring main groups. Each main group comprises recurring geometrical subgroups and recurring setting subgroups. Each geometrical subgroup comprises teeth of at least two different heights, high and low respectively, and comprises an even number of teeth. Each setting subgroup comprises teeth of at least five types, normal left set, medium left set, unset, medium right set and normal right set respectively, and comprises six teeth.

Abstract: A bandsaw blade (1a) includes a strip and teeth (1-9) projecting therefrom, which teeth (1-9) are arranged in recurring main groups, each main group comprising at least two recurring setting subgroups. The overall set magnitude is the same for each one of the setting subgroups and the individual set magnitude for at least one certain tooth (1-9) in a certain position in a certain setting subgroup differs from the individual set magnitude for the corresponding tooth (1-9) in the corresponding position in at least one of the remaining setting subgroups in the main group.
