Abstract: Devices for fastening cutting elements provided with clamping pockets to tool holders are often equipped with a clamping arm which, to secure the cutting element in a horizontal and perpendicular direction in at least one clamping pocket, is supported on this cutting element and which, via a fastening unit with a clamping direction towards the toolholder, is connected to this toolholder. If the clamping arm has several clamping fingers lying next to each other, these clamping fingers each engage in a separate clamping pocket. To improve the clamping effect of the clamping arm by producing an action of force not only in the direction of the bearing surface of the cutting element and to increase the efficiency of the fastening device, the clamping arm (4) has several clamping fingers (14, 15) which engage in the clamping pocket and are designed in such a way that they can be moved elastically towards one another in the clamping plane (arrow 13) of the fastening element due to a gap (11) which separates them and lies outside the fastening element. In other words, the clamping fingers (14, 15) lie one above the other in the clamping direction. At least one of the clamping fingers, as a preloaded element (15), causes the cutting element (3) to bear laterally transversely to the clamping direction; the at least one further main clamping finger (14), as main clamping element, ensures that the cutting element bears on the toolholder in the clamping direction. <IMAGE>

Abstract: A swept wing (10) for jet transports having a thickness-chord length (t/c) ratio that continuously decreases (i.e., tapers) from the wing root (14) to the wing tip (16) is disclosed. The tapered t/c ratio wing has reduced weight and improved overall efficiency when compared to conventional, constant t/c ratio wings. While the t/c ratio of the wing tapers, the combined structural and skin strength of the wing remains adequate to handle bending loads imposed by lift and engine weight. In this regard, the cross-sectional thickness of the midspan region of the wing is choosen such that the wing skin thickness can be reduced to the minimum allowable for the skin material. Also, the cross-sectional thickness of the outboard region of the wing is decreased, resulting in decreased drag and weight in this region. Further, the camber of the outboard portion of the wing is increased (as compared to the camber of a constant t/c ratio wing) to prevent the unsweeping of spanwise oriented isobars (54).

Abstract: A singlet lens is disclosed including opposing first and second refracting surfaces having spherical curvatures C 1  and C z , respectively, and a radial refractive index gradient wherein the refractive index N of the lens varies with radial distance r from the optical axis of the lens approximately according to the power series expansion formula: 
           Adjustment of the third-order spherical aberration of the lens to a value of about zero is effected by selective adjustment of the power series coefficient N 20 . Adjustment of the third-order coma of the lens to a value of about zero is effected by selective adjustment of the curvature of the first refracting surface C 1 . The remaining aberrations of the lens are sufficiently reduced that the lens exhibits an rms optical path difference not exceeding about λ/2 throughout the entire image field, and the power series coefficient N 10  and the curvature of the second refracting surface C 2  are selected such that the lens exhibits an rms optical path difference not exceeding about λ/1/3 at field heights below 0.7. The lens is particularly suitable for use as a video-disk lens.

Abstract: A conductor roll used for masking one face of a metal strip while the other face is being electro-treating comprises an elastomeric-covered cylinder having a metallic contact ring (3) in the center thereof for electrical contact with the strip being treated. To minimize high transfer current densities, each edge of the contact ring has a cantilevered flange (4) overlying a portion of the elastomer (5). It has been found, due to differential thermal expansion at operating temperature of both the elastomer and the metal contact ring; that the cantilevered flange section of the contact ring is forced up to an excessive extent, resulting in high bending stresses generated in the strip at the region of the contact ring-elastomer interface. By providing a taper on the cantilever flange section to compensate for the difference in thermal expansion, bending stresses in the strip are reduced to insignificant values, thereby eliminating creases and scratches in the strip.
