	Clutch plate for use in friction clutches of motor vehicles and the like - Patent 4548309
		The frustoconical surfaces 15 and 16' of the components 13 and 16 of the friction generating assembly 9 cooperate to accurately center the unit B on the unit A. This is due to the fact that the surfaces 15 and 16' are complementary and preferably congruent.
		The frustoconical peripheral surface 15a of the friction disc 13a is caused to bear against the complementary or congruent frustoconical internal surface 16a' of the component 16a by a diaphragm spring 18 whose radially outermost portion reacts against the flange 3 and whose radially innermost portion bears against the friction disc 13a.
		The cooperating surfaces 31b' and 16b' furnish a highly desirable centering action to thus ensure that the axis of the unit B coincides with that of the unit A. Furthermore, the surfaces 31b', and 16b' oppose rotation of the unit B relative to the unit A and/or vice versa.

		The flame of a lamp was then brought near the first surface of the crystal, and in such a position that the central part of the beam converging to the aperture should have an incidence of between 15° and 16°.
		When the plate on the second surface was slightly shifted, so that the line connecting the two apertures no longer coincided accurately with the line joining the cusps on the wave-surface, the phaenomena rapidly changed, and ultimately resolved themselves into the two pencils into which a single ray is divided under ordinary circumstances.
		The rays which in the first experiments filled the whole of the conical space, parted in the centre, when the aperture was much diminished; and the section of the cone, instead of a complete luminous circle was reduced to a luminous annulus, whose breadth diminished with the aperture.
