Abstract: 628,573. Lathe details. MANUFACTURE DE MACHINES DU HAUT-RHIN SOC. ANON. Aug. 28, 1946, No. 25761. Convention date, Nov. 7, 1944. [Class 83 (iii)] In an automatic lathe with a worm-shaft 3 which receives either a high or a slow speed drive from a constant-speed auxiliary shaft 1, the slow speed being dependent on a free-wheel drive 14, the change of speed is effected by a coupling member 11 mounted on the shaft 3 and controlled by a spring 22 and a cam-shaft 2. The shaft 1 carries two gears 9 and 12, the latter driving the shaft 3 through a gear 13 while the former engages a gear 8 provided with a clutch member and freely mounted on the shaft 3. The cam-shaft 2 is driven from the shaft 3 and carries a drum 15 having two catches 16 and 23 which operate levers 17 and 24 respectively. The lever 17 has an appendage 18 co-operating with a hook on a bell-crank lever 21, one end of which is articulated with the lever 24 and engages a slot in the member 11. When the catch 16 deflects the lever 18 the levers 21 and 24 are free to pivot allowing the spring 22 to engage the member 11 with the gear 8 to increase the speed of the cam-shaft. The member 11 is disengaged from the gear 8 when the catch 23 restores the levers 24 and 21 to their undeflected positions where they are held by the levers 17. The coupling member may be positively operated. Specification 616,119, [Group XXIV], is referred to.

Abstract: 1500975 Welding by pressure; jointing CLARKE CHAPMAN Ltd 26 April 1976 [19 June 1975] 26095/75 Headings B3R and B3V Two components 10, 50 are retained relative to one another by one or more studs 30 each of which is positioned in a respective aperture in the component 10, and, following relative positioning of the two components, friction welded to the component 50 by being rotated in said aperture in rubbing engagement with the component 50, the aperture having a recess (18) to accommodate weld flash 46, and the component 10 being retained on the stud by a head or other formation of the latter, by application to the stud after welding of a spring clamp or of a wedge or other member entering a transverse aperture of the stud (such wedge expanding the stud), by deformation of the stud after welding, or, as shown, by a nut 40 threaded on the stud before or after welding. The invention is particularly applicable for under-water repairs. The component 10 may be a repair plate. A gasket may interpose the components. The components may or may not be forced together. As shown, the stud has a friction welding driving tool recess 36 (e.g. hexagonal), is centred in the component 10 by a bush 22 of low friction material, e.g. PFTE, and is initially retained in the component 10 by a C-clip 28 and the nut 40. The latter and the component 10 have complementary engagement cones (42), 20. To minimize the effects of water quenching, the stud is surrounded, within the recess (18), by a foam material 43, a cylinder 44 ensuring free rotation between said foam material and the recess bore. The frictionally engaging end of the stud may be flat, or for underwater application, chisel ended to cut away collected dirt and organisms. Retention of the nut on the stud during friction welding rotation may be by a locking pin or tang plate (not shown) yielding on nut tightening, or by handing the nut thread so that inertia tightens the nut into engagement with the driving tool.
