摘要： A hypodermic needle featuring a multi-beveled point geometry is disclosed. In one embodiment, the multi-beveled point features a primary bevel, a pair of tip bevels, and a pair of middle bevels each intermediate the primary bevel and a respective one of the tip bevels. The primary and middle bevels are provided at angles of inclination, measured between the central axis and a reference plane that are substantially identical. The tip bevels are formed at an angle of inclination respective to the central axis which is not equal to the angle of inclination at which the primary and middle bevels are formed. The resulting five-beveled point geometry contributes to a more continuous bevel face free of abrupt intercepts or transitions between the respective bevel faces, lessening the penetration force required to urge the needle point through skin, flesh, or other material.
摘要翻译： 公开了一种具有多斜角几何形状的皮下注射针。 在一个实施例中，多倾斜点具有主斜面，一对尖端斜面和一对中间斜面，每个中间斜面均位于主斜面和相应的一个尖端斜面之间。 主斜面和中间斜面以倾斜角度设置，在中心轴线和基本相同的参考平面之间测量。 尖端斜面以不同于形成初级和中间斜面的倾斜角度的中心轴线的倾斜角形成。 所得到的五角点几何形状有助于在相应的斜面之间没有突然截距或过渡的更连续的斜面，从而减小了将针尖推动通过皮肤，肉或其他材料所需的穿透力。

摘要： A sharpener apparatus includes a base, a linear bearing assembly mounted on the base, and a support block carried by the bearing assembly for reciprocating movement along a rectilinear path relative to the base. A planar abrasive surface underlies the support block which has one or more open channels for receiving workpieces in sliding relation with the longitudinal axes of the workpiece preferably inclined to the abrasive surface. A pusher member is supported by the support block adjacent each channel for applying a constant force longitudinally of the corresponding workpiece to urge its tip against the abrasive surface. Manual or powered reciprocating movement of the support block effects an abrasive action of the workpiece tips against the abrasive surface to form a highly accurate and repeatable tip geometry, such as a chisel point, on each workpiece.

The diameters are connected by a curved grinding surface the diameter of which increases progressively therebetween. The curvature of the grinding wheel in the first third portion between the major and minor diameters is of greater mean curvature than the mean curvature of the corresponding opposed portion of the workpiece transport means. The second third portion of the grinding wheel is of greater mean curvature than the mean curvature of the corresponding opposed portion of the workpiece transport means.

摘要： A device and method for shaping an end of an elongated workpiece is disclosed. The device comprises an elongated tubular handle containing a coaxially positioned elongated tubular member which is journaled for rotation within the handle. The tubular member protrudes from both ends of the handle and has a clamping means for securing an inserted workpiece therein on one end thereof and a retaining means on the other end which prevents the tubular member from sliding out of the handle unless the retaining means is removed. In operating the device, a workpiece is inserted into the tubular member to the desired length, clamped into that position, then is applied by the operator of the device to a revolving shaping tool, such as a grinder, whereupon the workpiece is caused to rotate by its contact with the revolving tool until the desired shape is achieved.
