Abstract: A traction surface cooling method and apparatus for traction drive transmissions capable of continuous speed ratio variation in which a traction lubricant is circulated over a defined sector of a traction surface spaced from the point of rolling frictional contact of that surface with a cooperating traction surface. Provision is made for wiping the traction surface at the leading end of the sector to cleanse the surface of lubricant for more effective heat transfer from the surface to freshly circulated lubricant, and at the trailing end of the sector for preventing an excessively thick film of lubricant on the surface proceeding to the contact point.

Abstract: A drag mechanism for a fishing reel includes a frustoconical brake element having a large surface area and a brake drum having a correspondingly large complementary surface in frictional contact with the frustoconical brake element. The brake drum is urged with variable force against the frustoconical brake element by engagement with a threaded adjustment member which is threadedly received on a shaft of the reel. The frustoconical brake element and the brake drum are sized to be received within a recess defined by a flange at the end of the line spools of conventional fishing reels.

Abstract: A process to supercharge and control a compressor comprising a single screw co-operating with at least two pinions in order to constitute as many partial compressors as there are pinions, such partial compressors operating in parallel and one of them at least being provided with a delivery control device, wherein the supercharging flow is injected into only one of the partial compressors and the delivery of the compressor is controlled from maximal delivery by reducing at first the deliveries of those partial compressors into which the supercharging flow is not injected.
