    • The rotatable wheel assembly includes a wheel member rotatably sandwiched between a pair of cover members. Grommetless securing means are provided on at least one of the cover members for securing it to the other cover member through an axial opening in the wheel member. The grommetless securing means, which in one embodiment constitute an adhesive patch formed on at least one of the cover members, also function as a pivot for rotation of the wheel member with respect to the cover members. In other embodiments of the invention, the grommetless securing means comprise an adhesive patch member, which can be formed as an appendage to one of the cover members, that spans an opening in one of the cover members to adhere to the other cover member through the axial wheel opening. In a further embodiment of the invention the grommetless securing means comprise tab members formed on one of the cover members to extend through the axial wheel opening and a tab reception opening in the other cover member for folding thereon. A sheet construction for the rotatable wheel assembly includes the wheel member and cover member in side-by-side relationship with separation and fold lines to facilitate arrangement of the construction into a rotatable wheel assembly. Mass production of the construction blank can be accomplished on a web wherein all separation and fold lines lie in the direction of movement of the web.
    • 可旋转轮组件包括可旋转地夹在一对盖构件之间的轮构件。 至少一个盖构件上设有无轨道固定装置,用于通过车轮构件中的轴向开口固定到另一盖构件。 在一个实施例中,构成形成在至少一个盖构件上的粘合贴片的无索引固定装置也用作轮构件相对于盖构件旋转的枢轴。 在本发明的其它实施例中,无套索固定装置包括一粘接贴片构件,该粘合贴片构件可以形成为一个盖构件的附属物,跨接在一个盖构件中的一个开口,以通过 轴向轮开度。 在本发明的另一个实施例中,无套索固定装置包括形成在一个盖构件上的突出构件,以延伸穿过轴向车轮开口和另一个盖构件中的用于折叠的接片开口。 用于可旋转轮组件的片材结构包括与分离和折叠线并排关系的轮构件和盖构件,以便于将构造布置到可旋转轮组件中。 施工坯料的大规模生产可以在网上完成,其中所有分离和折叠线位于幅材的移动方向上。

    • A calculational aid is provided, in the form of a slide rule, to facilitate calculation of damages inflicted by a nuclear detonation. The particular apparatus permits calculation of the effects of an air blast, due to static overpressure, resulting from such a detonation. Appropriate scales, properly spaced in particular relationships, are provided on a slide rule, thus providing a means for performing the calculational functions described above. The calculations utilize five parameters, and the present invention provides an apparatus for determining any one of the five parameters once the other four are known.

    • A manually operable computer for determining exposure settings of an X-ray machine comprising two juxtaposed scale members. Means are provided for supporting said scale members for movement relative to each other, a first scale on one of said members denoting thicknesses of a subject to be radiographed and a second scale thereon in predetermined fixed relation to the first scale denoting certain exposure settings of an X-ray machine. A third scale is provided on the other scale member denoting certain other exposure settings, said second and third scales together forming a single chart of exposure settings in the form of voltage, current and time. The first scale includes a plurality of non-linearly spaced dimensional indicia indicative of said thicknesses. The second scale includes a plurality of spaced indicia of one form of exposure setting, and the third scale includes a plurality of spaced indicia of a second form of exposure setting in generally parallel juxtaposed arrangement with respect to the indicia of the second scale. The indicia of the second and third scales when positionally related determines the settings of an X-ray machine to obtain a particular X-ray exposure. The spacings, values and positional relationship of the aforesaid indicia are further arranged and selected according to predetermined non-linear relationships as to provide X-ray exposure settings on the chart for different thicknesses of a given anatomical subject which will yield a substantially constant density radiograph, all other conditions of taking the radiograph remaining constant. Indexing means identifiable with selected ones of said dimensional indicia for determining the relative positions of said first and second members are provided on said supporting means.
    • 一种可手动操作的计算机,用于确定包括两个并列比例构件的X射线机的曝光设置。 提供了用于支撑所述标尺构件以相对于彼此移动的装置,其中一个所述构件中的第一刻度表示要被射线照相的对象的厚度,并且其上具有与第一刻度成预定的固定关系的第二刻度, X光机。 另一个比例尺上提供了第三个比例表示某些其他曝光设置,第二和第三刻度一起形成电压,电流和时间形式的单一曝光设置图表。 第一刻度包括指示所述厚度的多个非线性间隔的尺寸标记。 第二刻度包括一组形式的曝光设置的多个间隔标记,并且第三刻度包括相对于第二刻度的标记以大致平行并列的布置的第二形式的曝光设置的多个间隔标记。 当位置相关时,第二和第三刻度的标记决定了X射线机的设置以获得特定的X射线曝光。 根据预定的非线性关系进一步布置和选择上述标记的间距,值和位置关系,以便在给定解剖学对象的不同厚度的图表上提供X射线曝光设置,其将产生基本上恒定的密度射线照片 ,所有其他拍摄X光片的条件保持不变。 在所述支撑装置上设置有用于确定所述第一和第二构件的相对位置的所选择的所述尺寸标记可识别的索引装置。
