Patent FR-2205388-A1 (FR)
Title: Multiple head welding machine - allows close spacing of heads in welding tubes to plate by not rotating head about its own axis
IPC: B21D39/06
Filed: 1973-11-08
Abstract: The welding head is mounted on a boom on which it can rotate in bearings. By means of a feeler finger which is held in contact with the inside of the tube the weld head follows the joint line between tube and plate without rotating on its own axis. Welding wire can therefore be fed from a fixed spool and current via a sleeve and clamp. Since the wire feed and other auxiliaries do not rotate, burners can be placed close together. A constant welding speed can be maintained to produce better welds.

Title: Degasification of water of car engine cooling system - using swirl chamber with tangential inlet and outlet in secondary circuit to extract gas bubbles
IPC: F01P11/02
Filed: 1975-07-11
Abstract: The car engine (1) has a water pump (2) which pumps water through the inlet (3) into the engine. The water flows from the outlet (4) to the radiator (5) and returns by the pipe (G). A secondary circuit (S) takes water from the cylinder head (10) and directs it around the carburrettor (12) to the swirl chamber (14). The water enters the swirl chamber (14) by the tangential pipe (17) and leaves by the tangential pipe (18). The swirling motion generated by the tangential entry separates the gas bubbles from the water so that the bubbles leave by the pipe (17) from the centre of the upper hemi-spherical cap (19). The gas velocity is reduced by the restrictor (33) before entering the expansion tank (30).

Title: Catalyst for steam-reforming and methanisation - consisting of impregnated sintered metal coating on a metal surface
Inventor: GOLEBIOWSKI ANDRZEJ
IPC: B01J37/02
Filed: 1975-12-05
Abstract: Catalyst bonded directly to a metal surface used for heating the reaction mixt. is made by (A) producing a highly porous metal sponge from powder by known sintering methods, (B) impregnating the sponge with salts and calcining to give >=1 non-reducible oxide (esp. Al2O3) and >=1 reducible oxide (esp. NiO) in combined amount not greater than the wt. of sponge, and (c) reducing the second oxide in the porous layer. The sponge layer is pref. made by >=2 sintering operations, with the finer powder bonded to the metal surface. Catalyst is used in steam-reforming of hydrocarbons, esp. methane, to CO/H2 mixts. and the reverse reaction for methanisation of CO/H2 mixts. Activity is at least as good as known catalysts on ceramic carriers, and thermal conductivity is much improved. The metal sponge gives high strength and adhesion e.g. to the metal walls of reforming reactor tubes. Recrystallisation of the active catalyst is prevented by the non-reducible oxide, which also determines the surface area.

Title: Electroslag welding of steels for use at sub-zero temp. - using controlled cooling of weld to ensure high notch toughness
Inventor: KUZMAK E M
IPC: C21D9/50
Filed: 1975-12-16
Abstract: The parameters of thermal cycles during electroslag welding, in which sections of the solidified seam and the adjacent metal of the workpiece are cooled. Additional cooling is simultaneously provided for the entire area of the sections exposed to heat in the range from the m.pt. to the A1 temp. and the cooling speed is arranged so that it increases with the distance from the sections which are near the m.pt. towards the sections with max. temp. A1. The cooling is pref. designed to prevent the pptn. of free ferrite during cooling of austenite and the pref. devices use coolant channels so that desired cooling rates are achievable. Welded structures with thick sections made of normalised or heat-treated low alloy steels and intended for use at sub-zero temp., may be treated by the process. The transformation of austenite into brittle structures during the cooling of welds is prevented and hence superior notch-toughness is obtd. in the welds at sub-zero temp.
