Abstract: 588,795. Variable-pitch propellers. ESCHER WYSS MASCHINENFABRIKEN AKT.-GES. March 7, 1945, No. 5671. Convention date, March 8, 1944. [Class 114] A hydraulically-operated variablepitch propeller is adjusted by a piston 6, operating within a cylinder 4, which forms part of the propeller shaft, and supplied with liquid under pressure by a pump 13, 14 actuated by a motor 18 mounted on the propeller shaft 12. The pump 13, when rotating in the direction D, draws liquid from a receptacle 11 and delivers through a passage 21 to a space 8 on one side of the piston 6, while pump 14 draws oil from space 7 on the opposite side of the piston, through passage 22, and delivers it to the receptacle 11. The pump wheel 13 also delivers liquid to the piston valve 24, to open a passage 25 leading to the upper side of a spring-loaded piston 27, which normally presses the ribbed end of the plunger 27<1> against the threads formed on a rod 9 of the piston 6 to lock the piston in its adjusted position, thus depressing the piston 27 and allowing movement of the piston 6 to adjust the propeller blades. On the reverse motion of the pump wheels 13, 14 the piston valve 24 is moved to open passage 25 to the wheel 14. High-level reservoirs 33, 36 maintain a supply of oil to the receptacle 11 and also to the blade setting mechanism within the propeller hub. The motor 18 is reversible and under control of a manual switch 52. The position occupied by the piston 6, and consequently the setting of blades is indicated by a core 42, secured to the piston and movable in a solenoid 41 to - actuate a visible indicator 51. In a modification, a single wheeled pump acts as a counterweight to the motor and the receptacle is provided within the piston 6, having'an automatic change-over valve, isolating the pressure side of the piston from the receptacle. In a further modification, the motor and-pump are mounted in a cylindrical space within the shaft coaxial with the cylinder 4.

Patent GB-714951-A (GB)
Title: An improved process for the reduction of ores
IPC: C21B13/00
Filed: 1952-03-06
Abstract: In a process for the reduction of ores, especially iron ores, a charge of a mixture of the ore and a reducing agent is heated to reduction temperature in a tunnel or like furnace and is then cooled by a counter-current flow of air or other oxidising gases which are burnt in the furnace, the charge being covered with a porous covering layer of fine grained, non-combustible material to prevent re-oxidation of the reduced material by the gases.  The covering layer, which should be porous enough to allow gases produced by the reduction to pass outwardly and should sinter to a compact mass at the end of the combustion zone where the temperature is highest, may consist of fine-grained ore of substantially the same quality as the ore to be reduced, feldspar or tailings from the production of ilmenite concentrate, and may have a compound added to promote sintering.  Where carbon monoxide is produced by the reduction, e.g. in the reduction of iron ore by coke, this is burnt in the oxidizing atmosphere together with the heating fuel.  After cooling, the covering layer is separated from the charge by screening, is crushed and is returned to the process as part of the new charge, while the cooled charge is separated from any excess reducing agent, ash or gangue by crushing and magnetic separation.  The counter-current of air may be drawn in to the furnace by a fan at the feed end.
