Abstract: Disclosed herein are expanding spinal fusion cage embodiments including an expandable cage assembly configured to expand from a collapsed state to an expanded state in an intervertebral space when inflated with a material. The assembly can include an inflatable section defining an interior volume configured to receive the material and expand the interior volume in response to a pressure from the received material to cause the expandable cage assembly to transition from the collapsed state to the expanded state, and a stabilization section configured to restrain the inflatable section during inflation.

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 phased array ultrasonic probe may be mounted to a component to be inspected for wall thickness on an apparatus that includes a split ring adapted to be magnetically held in place on the component. In particular, the probe may be mounted to a carriage connected to the split ring in a manner that allows the carriage to rotate around the split ring while the probe is in operation. Between the probe and the component, a transducer shoe defining, by a flexible membrane, a cavity and an aperture. Conveniently, the construction of the flexible membrane allows wall thickness measurements to be acquired in portions of the component that have complex topography, such as welds. The apparatus is installed on an adaptor assembly for inspection of straight section of pipes. This adaptor assembly is not used in absence of straight section.

Abstract: To avoid the detrimental effects of bubbles in the carrying out of immersion ultrasonic testing, various surfaces may be coated with a coating that includes appropriately selected compounds. Such compounds may include those compounds that cause higher local surface tension and those compounds that are hydrophilic. Furthermore, various surfaces involved in the testing may be coated in a manner that minimizes cavities and crevices to which air bubbles can adhere.

Abstract: A unique guitar has a head section with a base member connected to a support member. A string tuning unit is configured to be positioned on and be removeably secured to the support member in order to maintain the string tuning unit as part of the head section. The guitar secures strings to its bridge by use of uniquely designed pins, each having a slotted top section with a bottom stem offset from the top section and extending therefrom.

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.
