Manual operation.- Movement of an aircraft control surface, not shown, connected to tandem pistons 4, 41 is caused by the pilot pushing or pulling a link 5 that is connected by a floating lever 6, links 7, 9, 9<SP>1</SP>, plungers 80, 80<SP>1</SP> and springs 8a, 8a<SP>1</SP> to tandem pistons valves 8, 8<SP>1</SP>; a deformable parallel linkage system is formed by members 7, 9, 80, 81 and 9<SP>1</SP> so that movement of valves 8, 8<SP>1</SP> from the neutral position shown enables pressure fluid to be supplied from inlets 11, 11<SP>1</SP> to one side of each piston 4, 41 and to connect exhaust lines 23, 23<SP>1</SP> to the other sides thereof. Translation of the pistons 4, 4<SP>1</SP> alters the position of the lower end of lever 6 and hence restores the valves 8, 8<SP>1</SP> to the neutral position. Automatic aperation.-Electrical signals which are a measure of the sense and magnitude of the deviation of the aircraft from a given reference condition are fed to the differential coils of electro-hydraulic units 32, 32<SP>1</SP> to control polarized armatures having vanes 38, 381 in chambers 37, 37<SP>1</SP> supplied through passages 35, 36 and 35<SP>1</SP>, 36<SP>1</SP> and orifices 33, 34 and 33<SP>1</SP>, 34<SP>1</SP> from inlets 11, 11<SP>1</SP> respectively; chambers 37, 37<SP>1</SP> are connected to exhaust lines 23, 23<SP>1</SP>. Downstream of the orifices, passages 35, 35<SP>1</SP> and 36, 36<SP>1</SP> lead via passages 40, 40<SP>1</SP> and 43, 431, and a valve member 41, 41<SP>1</SP> to conduits 42 and 42<SP>1</SP>, respectively, which open at opposite ends of the valves 8, 81 whereupon any movement of the vanes 38, 381 produces a pressure differential across the ends of the valves 8, 8<SP>1</SP> thereby translating the latter and adjusting the control surface as described above. If the pressure drops in the system connected to one of the inlets 11, 11<SP>1</SP> then a corresponding drop occurs in the associated chamber 44 or 44<SP>1</SP> whereby the valve member 41, 41<SP>1</SP> is displaced to cut-off the related passages 40, 43 or 401, 431. A similar action takes place should a failure occur in either of the units 32, 321 due to automatic or manual de-energization of an associated solenoid-actuated check-valve 26 or 261 inserted in the fluid pressure lines leading to chambers 44 or 44<SP>1</SP> respectively. Should the pressure in either inlet 11, 11<SP>1</SP> fail then a corresponding valve 24, 24<SP>1</SP> will be urged by its spring to effect interconnection of the two sides of the associated piston 4 or 41.

Abstract: 1401816 Electrically charged filters CARBORUNDUM CO 1 Sept 1972 [10 Sept 1971] 40524/72 Headings BID BIT and B2J [Also in Division B5] A fibrous filter element 50 or granular filter bed (Fig. 11 not shown) is rendered conductive by inclusion of carbon and connected to an electrical potential supply 44 which delivers 0.001 to 100 volts, D.C. or A.C. at 2 to 60 c/s to assist removal of particles from liquid or gas passing through the element/ bed. In Fig. 10, element 50 is insulated from parts 40, 46 of its housing but in electrical contact with part 42. Gaskets 48, 52 are insulating. Fluid flows from 54 to 56, and supply 44 creates a potential between the element and metal parts 40, 46. In Fig. 12 (not shown) the element is connected to the metal ends of the housing to form part of a closed circuit with supply (80), part (76) being non-conducting. In Fig. 9 (not shown) supply (34) is connected between the element and an upstream metal grid which charges particles in the fluid oppositely from the element. Fig. 11 (not shown) is similar, but the element is replaced by a granular bed of sand, coal, glass or diatomaceous earth coated with carbon and binder. Figs. 1-8 (not shown) illustrate how filter elements of sheet material may be flat (Figs. 4, 5), annular and pleated (Fig. 6) or annular and spirally wound (Fig. 7). The sheet material may comprise two layers of felted, non-carbon, fibres bonded together by a layer of resin and carbon particles (Figs. 1, 2), or a single felted layer incorporating resin and carbon powder or carbon fibres. Alternatively fibres made by extruding a rayon-pulverised carbon mixture are used alone or with other fibres, being moulded (Fig. 8) or wound honeycomb fashion on to a core sleeve. Metal end caps (29), possibly covered by plastics insulators (37) may be bonded to the elements by conductive resin-carbon mixture.

Title: Extrusion press with rotary die-holder carrier
Inventor: SAMUEL HERBERT JOHN
IPC: B21C23/21
Filed: 1960-11-25
Abstract: 939,036. Extruding. LOEWY ENGINEERING CO. Ltd. Nov. 27, 1961 [Nov. 25, 1960], No. 40533/60. Class 83 (4). In a metal extrusion press having separate die and bolster assemblies, these assemblies are each rotatable about spaced apart axes which are parallel to the extrusion stroke. The press, which may be horizontal or vertical, has a platen 10 connected by three columns 11a, 11b, 11c to a main cylinder (not shown). A billet container 12 is axially movable by means of hydraulic units (not shown). Mounted about the column 11a is a rotatable die carrying arm 21 carrying die assemblies 14, 114 at each end; it is rotated by a motor 24 and gears 22, 23. The bolster assembly 18 is mounted at one end of an arm 25 rotated about column 11b by an hydraulic unit 26, 27 pivoted at 28 to a fixed bracket 29. Dotted lines in Fig. 2 indicate the position to which the bolster may be swung for easy access to it. The bolster and/or die carriers may rotate through a full circle, or oscillate. A motor-driven saw 34, for cutting the extruded work from the billet residue is pivotable about column 11b by means of a piston and cylinder unit 36. When extrusion has been completed, the arm 21 is moved axially of the column 11a to allow the saw 34 to enter between the die 14 and bolster 18.  The die assembly shown in Fig. 3 comprises a die 15 mounted in a " U "-shaped holder 16, in which is also mounted a first shear plate 17. The bolster 19 has mounted on it a second shearing plate 20. The shearing plates 17, 12 hold knives 33, 32. Thus, instead of the extruded section being cut by means of the saw 34, it may be sheared by relative arcuate movement of the die and bolster. If, for example due to cooling of a billet during extrusion, an unextrudable portion of a billet remains in the billet container, it can be removed. The container 12 is withdrawn and the extruded portion cut from the billet by the saw 34. A horseshoe shaped distance-piece is mounted at 114 on the die arm 21 and swung into the working position. The bolster assembly is swung out, the bolster replaced by a ring of sufficient internal diameter to accommodate the billet, and the bolster carrying arm returned to the working position. The ram then ejects the billet remainder through the distance-piece and into the ring placed on the bolster arm.
