摘要： An expandable mandrel for holding a workpiece, including a mandrel body having an interior surface and an exterior surface. The interior surface defines at least first and second interior regions separated by a transition surface, the first region having a cross sectional area greater than a cross-sectional area of the second region. A plurality of slots extend between the interior surface and the exterior surface. A slave actuator having a bearing surface is at least partially disposed in the first region, and a master actuator is provided for urging the bearing surface against the transition surface to expand the mandrel against the workpiece.

摘要： A device used to hold/support a target or multiple targets in the ground for the purpose of target shooting with firearms, air guns, and the like. This target supporting device allows any size or thickness material typically used for target shooting to be securely embedded into the ground, regardless of the slope of the ground to the line of fire. Additionally, any type of card, board, or sign can be supported in the ground to post information such as yard sales, keep off the grass notices, trail maintenance, etc.
摘要翻译：用于在火炮，气枪等进行目标射击的目的或者支持地面上的目标或多个目标的装置。该目标支持装置允许通常用于目标射击的任何尺寸或厚度的材料被牢固地嵌入地面，而不管地面到火线的倾斜度。另外，地面上可以支持任何类型的卡，板或标志，以张贴诸如场地销售，草稿通知，跟踪维护等信息。

摘要： A removable ice cleat for an outer frame member of a snowshoe provides traction for snow packed and icy conditions. For looser conditions including powdery snow, the ice cleats are quickly removable thus making the snowshoe versatile for all weather conditions. The ice cleat is attached using a metal band clamp that is tightened by a screwdriver or nut driver thereby making deployment of the ice cleats possible while outdoors. The ice cleat has an ice pick that is clamped by the band to the bottom of the outer frame member of the snowshoe. Several ice picks can be clamped in this manner. The picks have legs that extend downwardly and outwardly from a mid portion thereof to pointed ends having a generally triangular shaped penetrating portion that maintains good penetrability even as the pointed end becomes dull.
摘要翻译：用于雪鞋外框架构件的可拆卸的防滑板为积雪和冰冷条件提供牵引力。对于松散的条件，包括粉状雪，冰夹可以快速拆除，从而使得雪鞋在各种天气条件下都具有通用性。使用由螺丝刀或螺母扳手拧紧的金属带夹将冰楔连接起来，从而在室外可以部署冰夹。冰夹具有一个冰带，被冰带夹紧到雪鞋的外框架构件的底部。可以以这种方式夹住几个冰镐。拾取器具有从其中间部分向下和向外延伸的端部，其具有大致三角形形状的穿透部分，即使当尖端变钝时也能保持良好的穿透性。
