    • A device for identifying the size of bolts and nuts is provided and consists of a plate. A first mechanism on the plate, is for measuring different sized threaded shanks of unidentified loose bolts. A second mechanism on the plate, is for measuring different sized unidentified loose nuts. A third mechanism removable from the plate, is for measuring different sized unidentified threaded studs mounted on massive objects. A fourth mechanism removable from the plate, is for measuring different sized unidentified threaded apertures in massive objects. Indicia is disposed on the plate for indicating the sizes of the bolts and nuts.
    • 提供一种用于识别螺栓和螺母尺寸的装置,并由一块板组成。 板上的第一种机构是用于测量不确定松散螺栓的不同尺寸的螺纹杆。 板上的第二种机制是用于测量不同尺寸的未认出的松散的坚果。 可从板上移除的第三种机构是用于测量安装在大块物体上的不同尺寸的未认出的螺柱。 可从板上移除的第四种机构是用于测量大块物体中不同尺寸的不明身份的螺纹孔。 标记设置在板上用于指示螺栓和螺母的尺寸。

    • A template set for use in corneal size measurement. The templates take the form of identical thin and flexible blades rounded at one end, and are arranged in a stack in parallel planes. The blades are pivotally coupled together adjacent their opposite ends by a pivot pin which extends through the whole stack. The pivot pin allows individual blades to be pivoted out of the stack for use. Each blade has a circular opening adjacent the rounded end of the blade and the openings are graduated in size in predetermined increments from one end of the stack to the other. Each blade is also visibly marked to indicate the size of the opening.
    • 用于角膜尺寸测量的模板集。 模板采用相同的薄且柔性的叶片的形式,其一端是圆形的,并且以平行的平面布置在一个堆叠中。 刀片通过延伸穿过整个堆叠的枢轴销枢转地联接在一起,邻近它们的相对端。 枢轴销允许单独的叶片从堆叠中枢转使用。 每个叶片具有邻近叶片的圆形端部的圆形开口,并且开口的尺寸从堆叠的一端到另一端以预定的增量分级。 每个刀片也被明显地标记以表示开口的尺寸。

    • A sizing gauge for determining the proper size of heart valve for implantation in a natural heart valve orifice. The sizing gauge includes a handle which can be gripped by a surgeon, a sizing ring having a smooth outer surface and a hollow interior, and connecting struts connecting the sizing ring and the handle. The connecting struts is so constructed and arranged as to afford direct visual observation by the surgeon of heart tissue beyond the sizing ring when the latter is inserted in a heart orifice. Outer surfaces of the connecting struts diverge forwardly for connection to the sizing ring and merge with the outer surface of the sizing ring to permit the latter to be eased outwardly through the natural heart valve orifice.
    • 用于确定用于植入在天然心脏瓣膜孔中的心脏瓣膜的适当尺寸的定径计。 定径计包括可由外科医生抓握的手柄,具有光滑外表面和中空内部的定径环,以及连接尺寸环和手柄的支柱。 连接支柱被构造和布置成当心脏组织的外科医生在心脏组织插入心脏孔时超过定径环时提供直观的视觉观察。 连接支柱的外表面向前发散以连接到尺寸调节环并与尺寸调节环的外表面合并,以允许后者通过自然心脏瓣膜孔向外缓和。
