In the storage of parts (e.g. engine valves) between manufacturing operations (Fig. 1) parts are fed along a path 30 and 32, and enter an ascending spiral 33 at the top of which they either move along a path 31 to the next manufacturing operation, or are moved around a descending spiral 35 and are fed again at 36 to the ascending spiral 33. In the latter (Fig. 3) the article is supported on stationary spiral 38 and is progressed upwards therealong by the movement of spiral 39 which is carried by framework 40. This is given a vertical movement at 46 by a cam secured to a shaft 48, and is given a horizontal movement by means of a crank-pin 56 also secured to the shaft 48. In this way the spiral 39 performs a cyclical movement which moves the parts step-by-step up the spiral 38. The discharge of articles at the bottom of spiral 33 is controlled by switching gate 84 (Fig. 11) and stop 89 operated by cylinders 85 and 91 respectively. The descending spiral 35 (Fig. 12) is formed of wires 35 secured by means 102 to the outside of a stationary cylinder 101 adjustable at 103. In a modification (Fig. 25) the two spirals, the ascending spiral 122 and the descending spiral 124, are formed round the same axis. Each track is formed of two parts of which one is a stationary spiral which supports the articles, and the other is a moving spiral which urges the articles either up the spiral or down.

Abstract: 1,250,324. Deflecting propulsive jets. GENERAL ELECTRIC CO. 6 Dec., 1968, No. 58049/68. Heading B7G. [Also in Divisions F1 and F2] In a cascade of airfoil vanes for directing a propulsion jet, each vane consists of a fixed uncambered part 14 and a movable part 16, which is thicker and longer, pivoted at 18. In the deflected positions, the ratio of areas A 1 , A 2  are such that the vanes form converging nozzles, from the pivot point 18 to the throat circle 32, thereby causing an increase in fluid velocity and a pressure decrease. The vanes are proportioned and disposed so that, on deflection, the overall effect is for the flow to remain attached and not separate from the suction surface 36 near the hinge point of the lower vane. Additionally the fixed forward portion 14 causes a reduction in the angle of attack, so the normal streamline 40 has its curvature approaching the pivot 18 of the airfoil reduced to assume a new position 42. Movable port 16 can be cambered.
