| -12- GALLAY RADIATORS Are fitted to a great number of cars in the Salon, amongst others the latest Citroen, Hispano, Peugeot, Talbot, Chevrolet and Mathis. Until recently they fitted zig-zag ribbon matrices but now they have incorporated a large amount of indirect cooling with the zig-zag ribbon. (See sketch). They state that in consequence, where they originally supplied matrices 100 mm. deep, they can now cool the same cars adequately with the new matrix 70 mm. deep. NEW GALLAY MATRIX Lowering the Chassis. The Ansaldo now carry their cross members under the torque tube. It is not clear how they restrain the rebound of the spring sufficiently to accomplish this. Wheels at the back. Voisin Isotta and others have fitted trunks at the side (where we normally carry the spare wheels) when they fit two spare wheels at the back. VOISIN MAGNETIC RELAY. The only competitor to the Maybach Overspeed is the Voisin magnetic relay. This is nothing more than a two speed epicyclic gear operated by electro magnets and used in conjunction with an ordinary gearbox. The magnetic | ||
