    • Raccordement fileté où la charge axiale entre une vis (11) et un écrou (15), lorsqu'ils sont vissés ensemble, est répartie de manière plus équilibrée entre les différents tours des filetages qui entrent en prise que dans un raccordement standard. A cet effet, le pas du filetage (14) de la vis (15) augmente progressivement (Pa, Pb, Pc) à mesure que le filetage avance hélicoïdalement dans un état axial prédéterminé, tandis que le pas (P) du filetage (13) de la vis (11) est uniforme sur toute sa longueur. Le pas du filetage de l'écrou (14) peut augmenter de manière prédéterminée pour compenser les variations de la force de traction qui s'exerce sur la vis (11) et de la force de compression qui s'exerce sur l'écrou (15) en différents points sur leur longueur lorsque la vis (11) et l'écrou (15) sont vissés ensemble jusqu'à un état précontraint.

    • A radiation collector (10) having a flexible reflective wall (28) which is deflected to a curved preferably paraboloidal configuration by application of differential pressures to opposites sides of the wall (28). A structure extending essentially circularly along the periphery of the flexible reflective wall (28) preferably restrains the peri­pheral position of the wall (28) against constriction radially inwardly upon application of the pressure differential to the wall (28), in a relation causing the wall (28) to assume an ultimate configuration corresponding more closely to that or a true paraboloid than if the restraining structure were not present. Desirably, the pressure differential is predetermined and regulated to give the reflective wall (28) a substantially exactly paraboloidal shape.
    • 具有柔性反射壁(28)的辐射收集器(10),其通过将差压施加到壁(28)的相对侧而偏转到弯曲的优选抛物线构造。 沿着柔性反射壁(28)的周边基本上圆形延伸的结构优选地以使得壁(28)的压力差向壁(28)施加压力差而径向向内收缩的周边位置 (28)相比,如果不存在限制结构,则采取与该或真正抛物面更接近的最终构造。 理想地,压力差是预定的并被调节以使反射壁(28)具有基本上完全抛物面的形状。

    • A process and apparatus for forming threads of varying pitch on a work piece, by first producing a partial thread (72, 73, 74, 75, 76, 77 in Fig. 3) and groove whose pitch does not vary in accordance with a pattern of pitch variation desired for the final product, and then reshaping the partial thread and groove to a final form (71, 72, 73, 74, 75, 76, 77 in Fig. 4) whose pitch does vary in accordance with the desired pattern. The two steps may be performed by a single tool (16) having a series of thread cutting projections (21c, 21d, 21e, 21f, 21g, 21h) which form the partial thread, and having one or two additional projections (21a, 21b) which then reshape the partial thread to its final form.

    • A radiation collector having a flexible reflective wall which is deflected to a curved preferably paraboloidal configuration by application of differential pressures to opposites sides of the wall. In one form of the invention, the reflective wall forms the back wall of an inflatable bag having a forward flexible wall through which radiation from a source passes to the interior of the bag for reflection by the rear wall toward an axis of the device. In another form of the invention, the reflective flexible wall is the front wall of a vacuum chamber and is deflected rearwardly by the differential between a subatmospheric pressure in the chamber and atmospheric chamber at the front of the wall. A structure extending essentially circularly along the periphery of the flexible reflective wall preferably restrains the peripheral position of the wall against constriction radially inwardly upon application of the pressure differential to the wall, in a relation causing the wall to assume an ultimate configuration corresponding more closely to that or a true paraboloid than if the restraining structure were not present. Desirably, the pressure differential is predetermined and regulated to give the reflective wall a substantially exactly paraboloidal shape.
