Heat-decomposable metal-bearing gas, e.g. carbon dioxide, containing nickel carbonyl vapour, is supplied to chamber 30. Inert gas is supplied to chambers 33, 34. Helium, nitrogen, hydrogen, or the gaseous product of the controlled burning of hydrocarbon gases free of oxygen, are alternative carriers for the metal. The metal to be deposited may be introduced as a gaseous metal carbonyl or a vaporized solution of the metal carbonyl, e.g. nickel, iron, chromium, molybdenum, and cobalt carbonyl in a solvent, e.g. petroleum ether, also nytroxyl compounds, e.g. copper nitroxyl ; nitrosyl carbonyls, e.g. cobalt nitrosyl carbonyl ; metal hydrides, e.g. tin hydride, antimony hydride ; metal alkyls; chromyl chloride and carbonyl halides, e.g. cerium carbonyl bromide, or ruthenium-carbonyl chloride. The heat of the rod 18 is sufficient to decompose the metal vapour and a coating of the metal is deposited on the rod. The coating may be subsequently annealed, e.g. by induction heating.

Headings F2E, F2L, F2S and F2U. A continuously-rotating input shaft 2, Fig. 1, is connected by a friction slip coupling, comprising oil-impregnated friction rings 5 adjustably gripped between a plate and disc 6, 7, to a shaft 11 driving paper feed &c. machinery, the disc 7 co-operating with a positive detent to stop the shaft 11 in one of a number of predetermined positions and a dashpot absorbing shock arising on engagement of the detent. Control of the detent may be effected automatically by a light-sensitive photo-electric system 13, 14 coacting with a radially-slotted disc 12 on the shaft 11. In one form, rotation of the shaft 11, Fig. 3 (not shown), is stopped on energization of an electromagnet 23 to project a detent 20 carried by an oscillatable carrier 32 into engagement with peripheral teeth on the disc 7, engagement of the detent turning the carrier so that a dashpot piston 36 is forced downwards against the bias of a spring 39, to expel fluid from a cylinder 37 through a triangularly-shaped orifice 43 into a surrounding housing 44. When the shaft 11 has been brought substantially to rest, energization of a second electromagnet 41 pivots a locking detent 30 into engagement with the toothed disc 7. The end of the dashpot 36 &c. is provided with a swivel bale 40 received within a pocket in a drain plug 45. In another form, a detent 20, Fig. 4 (not shown), coacts with teeth on the disc 7 and the working face 21 of each tooth contains a dashpot piston 16, which is forced into a hole 18 against the bias of a spring 17 to expel fluid through a duet 19. In yet another form, the teeth 15, Fig. 5 (not shown), on the disc 7 are engaged by a detent 20 pivoted by a link 23 about a pin 24 carried by the piston 27 of a dashpot including a closed cylinder 26. Oppositely-directed one-way valves 29 allow transfer of fluid within the cylinder 26 from one side to the other of the piston 27. Engagement of the detent 20 forces the piston 27 downwards against the bias of a spring 28 as far as permitted by a stop 41.
