摘要： A ball cage for a ball bearing of the angular contact type having a double row of balls with opposed angular contacts comprises a solid central portion which is bounded between two concentric cylindrical surfaces and between two parallel planes and has cells with part-spherical surfaces for receiving the balls in each axially directed side. Elastic lips having surfaces which form continuations of the part-spherical surfaces of the cells project from the central portion axially beyond the parallel planes and these lips permit the introduction of the balls into the cells in an axial direction and retain the balls in the cells elastically. There is only a single lip between each adjacent pair of cells at each side of the central portion and the lips at each side of the central portion are similarly oriented and each lip has, adjacent its base where it joins the central portion, an area which lies in one of the planes and has substantially the shape of two triangles arranged apex to apex with the minimum width of the area in the middle of the radial thickness of the cage.

摘要： 982,558. Watches. J. PARMENTIER. April 10, 1963 [April 10,1962], No. 14334/63. Heading G3T. In a waterproof wrist watch, the winding knob, or a fixed sealing cap 2 which covers it, projects on a side where the wristlet 6 is attached, and the case is provided with an articulated or hinged part 5 to which the wristlet is attached and which normally surrounds the knob or cap over a substantial part thereof to protect it, the part 5 being movable about its hinge 4 to a position where the knob or cap is exposed for manipulation. In Fig. 1 the part 5 protects a fixed sealing cap 2 over the winding knob. In an alternative, Fig. 5, the part 5a hinges about a pin 9 parallel with the watch axis and is formed integrally with a sealing cap which seals against a washer 8. The part 5a is retained by a releasable lever 10 having a catch which en- gages the part 5a. The parts are arranged so that a generally symmetrical appearance of the watch is preserved.
