Title: Improvements in and relating to flow controllers
IPC: G05D7/01
Filed: 1933-09-18
Abstract: 427,726. Valves. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(General Zeolite Co.; 333, West 25th Place, Chicago, U.S.A.) Sept. 18, 1933, No. 25750. [Class 135] A fluid-flow controller in which a loaded control or actuating diaphragm is subject to a pressure differential derived from the main conduit has means for varying the proportion of the desired pressure differential applied to the diaphragm. In the form shown in Fig. 1, the main valve 11 is controlled by a diaphragm 13 carrying a weight 21 tending to open the valve. The conduit above the valve is formed as a Venturi tube 12, the pressure at the full section being applied through a pipe 30 below the diaphragm, while the reduced pressure from the throat is applied through a valve 26 and pipe 29 above the diaphragm. The pipes 29, 30 are joined by a byepass having a constriction 28. The valve 11 is maintained open in a floating condition by a certain difference of pressure across the diaphragm, and its degree of opening may be varied to permit different rates of flow by adjusting the valve 26, thus varying the proportion of the pressure - difference in the Venturi applied to the diaphragm. In a modification, a swingable pipe is arranged to take pressure from the Venturi 12 at different points. In a further form the main pipe is itself of uniform section, and a shiftable conical member is arranged between the points of junction of the pipes 29, 30 with the main pipe. In the arrangement shown in Fig. 6, the main valve 56 is actuated by a bellows 61, controlled by an auxiliary valve 73, itself controlled by the Venturi 51. The interior of the bellows 61 is connected to the outlet and the space around the bellows is connected by pipes 70, 71 through the auxiliary valve 73 to the full inlet pressure at 52. The pipe 70 is also connected to outlet by a constriction 69, so that the pressure in the pipe 70 is determined by the degree of opening of the valve 73. The space above the actuating diaphragm 76 of the valve 73 is connected to the inlet through a fixed constriction 83 and to the Venturi throat 43 through a variable constriction 86 so that the pressure above the diaphragm 76 may be varied substantially between the pressure at 43 and 52. A float-operated valve, not shown, may be incorporated in the pipe 71 and adapted to close, so as to close the main valve 56 when the reservoir being supplied is filled.

Abstract: 785,367. Disc brakes. GIRLING, Ltd. Sept. 6, 1955 [Sept. 7, 1954], No. 25887/54. Class 103 (1). In a " spot-type " disc brake, the torque on the backing plates carrying the friction pads is taken by spaced pins mounted in parallel relationship to the axis of the disc in a rigid caliper housing. In the embodiment illustrated, brake discs or rings 16, 17 slidably keyed in an axial direction to the rim of an aircraft wheel 10 are adapted to be frictionally engaged by segmental shaped friction pads 27 and 29 to retard the wheel. A caliper housing 18 carrying the friction pads, backing plates and hydraulic cylinder 22, straddles the brake discs from the inside and is rigidly mounted by bolts 20 to a non-rotatable portion of the axle assembly. When the brake is applied, piston 23 forces the right-hand friction pad 27 carried by backing plate 28 against an adjacent braking disc 17 which moves axially and, through friction pads 29, urges the other brake disc 16 against rigid left-hand end pad 27 so that each brake disc is gripped between two friction pads. The torque on the pads is taken through the backing plates 28, 30 by pins 34 mounted in housing 18. The major part of the torque will be taken by one or other of the pins 34 according to the direction of rotation of the wheel. The torque-taking pins 34 may be inserted after the brake is assembled and are removable to permit the pads and backing plates to be removed from the housing in a radially outward direction when the wheel is removed.

Title: Treatment of iron ore
IPC: C22B1/02
Filed: 1950-10-31
Abstract: In a process for obtaining iron values from an iron ore, the ore is preheated to <PICT:0685250/III/1> at least 660 DEG F, reduced to magnetite by means of a gaseous reducing agent, and finally oxydized to magnetic haematite at a temperature between 390 DEG F and 950 DEG F, the heat required for carrying on the process being provided by the heat produced in the oxidation reaction.  As shown, raw material is fed into a reaction chamber 10 from a hopper 14 by a screw 15.  At the top of the chamber the raw material is preheated to 660 DEG F and then enters a reducing zone where it is treated with a reducing gas, mainly hydrogen with or without carbon monoxide, led in through a pipe 32, the hot ore being reduced to magnetite.  On descending further the magnetite is oxidized to magnetic haemitite by an oxidizing gas, e.g. steam and air, led in through a pipe 38, the heat evolved during this reaction heating up a carrier gas, e.g. nitrogen and some of the products of the process, which is directed through a by-pass round the reduction zone and led into the preheating zone. The coal gases coming from the top of the preheating zone are pumped to an inlet below the oxidizing zone where they cool the hot magnetic haematite which is finally discharged by a screw 24 and a hopper 28. Part of the gases from the preheating zone may be used to preheat the raw material in the hopper 14.
