Title: Process of fusion electrolysis for metal production
IPC: C25C3/00
Filed: 1960-09-07
Abstract: In obtaining the metals Ti, Zr, Mg, Al, B, Be, Th, and U by fusion electrolysis of their salts in the presence of alkali metal halides, there is added a compound containing the desired metal halogen, hydrogen, and nitrogen, preferably made by reacting NH3 with the metal halide, e.g. a loose compound of formula (NH3)xTiCl4. Preferably this is heated under reduced pressure in an atmosphere of NH3 at 1000 DEG C., the product being then stable to oxygen and water. Preferably the halogen present is the same as in the fused metal halide being reduced, but a different metal may be used in the added compound to form alloys, e.g. Zr/Ti. The electrodes used may be of the desired metal, carbon, Mn3O4 or chromium oxide. The added compound lowers the fusion point and reduces the formation of "smoke".

Patent ES-321541-A1 (ES)
Title: Improvements in or relating to the manufacture of tubular heat exchanger cores
IPC: B21C37/10
Filed: 1966-01-08
Abstract: A method of making a a heat exchanger core having at least one seamed tube and a number of collector plates 8 comprises, forming a metal strip into a tube having a pair of opposed, substantially parallel sides with a seam 1 along one of the remaining tube sides, the seam being flat crimped between a flat part of a mandrel and a crimping roll, and shaping and finishing the tube between rolls 4, 5 which co-operate with a rounded part 3a of the mandrel to impart a rounded profile to the seam outer surface. The tube, after passing through rolls 4, 5, is finished by a single roll (6), the action of the rolls 4, 5, (6) also serving to reduce the width a-b of a groove at the base of the seam formed during seaming, Fig. 3 (not shown). The tube, which may be of aluminium coated with aluminium silicon alloy brazing metal, is located at either end in apertures 12 formed in plates 8 of similar metal to the tube. The apertures 12 are punched, rather than stamped out, to provide a clean and accurate cut, and the plates 8 are preferably coated on both sides with brazing metal. Each opening 12 may be provided with a projection which engages in the groove at the base of the seam 1. In an alternative embodiment the plates 8 are stamped to form recesses with sloping sides 14 and the bottoms of the recesses are then punched to form the openings 12. The sloping sides guide the tube ends into the openings and the greater depth of the openings, due to being effectively cut obliquely to the thickness of the metal, gives a larger contact area for brazing.

Title: Improvements in or relating to machine drives
IPC: H02K7/10
Filed: 1968-03-16
Abstract: A two-speed constant mesh gear has a slip clutch in each power path to give infinitely variable output speed. The clutches are energized simultaneously for braking. As shown the transmission is employed between a squirrel cage motor 1 and a drum 16 of a tyre building machine and has magnetic particle clutches 14, 7 in the direct drive path and a layshaft 9 of a step-down train respectively.

For maximum braking both clutches are fully energized, or to obtain a predetermined deceleration from high speed the clutch 14 is fully energized and clutch 7 partially energized, while for braking from low speeds clutch 7 is fully energized and clutch 14 partially energized. As shown gear pairs 3, 12 are provided between the lay shaft and the input and output shaft if a reversing gear is required one gear pair is replaced by a belt drive. Electrostatic or eddy current clutches may be used instead of magnetic particle clutches.
