Title: Improvements in petrol tanks
IPC: B64D37/26
Filed: 1936-12-31
Abstract: 488,105. Aircraft emergency fittings. HALL, F. H. Dec. 31, 1936, No. 35784. [Class 4] [Also in Groups XVII and XXVIII] An aircraft petrol tank has an outlet 3 for the normal discharge of the petrol, means for admitting gas under pressure to the tank, a normally closed discharge siphon 5 independent of the normal outlet, means for automatically opening the siphon when the pressure is admitted to the tank, an air inlet 4 and means for closing the air inlet when said fluid pressure is admitted. When a cable 27 is pulled a cartridge 19 is fired and the resultant gases, passing through a flame trap 28 and pipes 16a, 16, push a piston-valve 9 to the left and thus, via links 13, 14, close the air-cock 15, open the siphon-cock 6 and uncover a gas inlet 8. Similarly, gases passing through a pipe 41 close the petrol outlet cock 31 and open a cock 34 which normally closes the air inlet or a petrol reserve chamber 30. A single large cartridge may supply pressure to several siphon-fitted tanks ; or one tank only may have a siphon, the other tanks being arranged to drain quickly into the said tank. The cock 6 may be dispensed with, the end of the siphon being normally closed by a disc of tin foil which is burst by the pressure of the gas on the petrol. Instead of a cartridge, compressed air may be used. Two or more cartridges in separate chambers may be fired in succession to obtain any desired pressure ; or the gas from the cartridge chamber(s) may be stored in a reservoir and passed to the tank through a cock or valve. The leg 5a of the siphon may depend into a sump or well in the tank. The Provisional Specification, which refers to Specification 433,198, [Group XXXI], mentions that the foil disc may be made of lead, that the lower end of the leg 5a may be perforated and that compressed carbon dioxide may be used.

W. ; Curren Terrace, Norristown, Pennsylvania, U.S.A.) Dec. 1, 1930, No. 36166. Convention date, Dec. 27, 1929. Addition to 366,965. [Class 4.] Modifications of the structure described in the parent Specification comprise beaded reinforcements for the channels of the struts, Fig. 4, a different method of connecting the struts one to another and to the chord members, Fig. 2, and the provision of channel reinforcing members for the chord members when the design of the fuselage necessitates curving these members, Figs. 9 and 10. The diagonal struts 16, Fig. 2, are welded to the sides of the chord member before attachment of the transverse struts 15 which are welded by inturned channel sides 32<1> to the appropriate channel side of the strut 16 before application of the gusset plate 36. Channels 41, Fig. 9, tapered toward either end are applied midway of the bays in which the chord members are curved and when welded to the sides of the inner chord member 21 form a box-section reinforcement, Fig. 10, progressively reduced in cross section from the centre of channel 41 to the ends. In assembly the lower chord members are held in a jig which imparts the desired curvature to them during welding of the members 41 ; next the upper and lower pairs of chords are assembled with the struts lying in planes transverse to the plane of symmetry and the two girders thus formed are then interconnected by the struts of the side walls of the body.

In a classifier the particles are classified in a rotary classifying zone 15, 22 through which the air flows inwardly and in which the flow crosssectional area vaires inversely as the radius and the air flow prior to entering the classifying zone is approximately parallel to the axis of rotation of the zone. In the double cone classifier shown in Fig. 2, the zone 15 is formed between rotary plates 12, 13 enclosing radial blades 14 and the rate of air flow is adjustable by a sleeve 16 controlling openings 6 and movable vertically by screws 17 operated by handles 18. The inlet 21 of the classifier shown in Fig. 3 receives the flow from a grinding-mill, the oversized particles rejected from the zone 22 being discharged by a return conduit 23 and the fine particles passing through the zone being discharged through a duct 24 which may be connected to firing equipment. In a modification, Fig. 4 (not shown), the upper plate is axially adjustable to vary the effective height of the classifying zone.

Each headlamp is carried by a fitting comprising cylinders and pistons one set of which is connected with an hydraulic fitting connected to the steering mechanism and the other (for dipping) to an hydraulic fitting under control of the driver. The construction illustrated is one in which only one lamp is swivelled at a time. Figs. 9 and 8 show diagrammatically the dipping and swivelling systems separated, 12, Fig. 9, being a member rotatable in horizontal bearings in one or other direction by a pair of pistons connected through pipe lines 44, 46 to a pair of cylinders u, w in a fitting on the steering column and carrying the lamp support 27 by means of a vertical axle 26, Fig. 8, rotatable by a plunger 19 having the pipe connection 42 with an hydraulic cylinder b in a fitting connected by a lever m with the steering. Cylinders t, v and pipe lines 45, 47 are the corresponding dipping connections for the other lamp and c and 42<1> the other swivelling connections. Referring now to the detail construction, the lever m, Fig. 1, connected with the steering drop arm, operates a slidable rod e carrying rods f, g slidable in pistons h, i in the cylinders 6, c communicating through the flexible pipes 42, 42<1> with bores 14 in the two members 12, Fig. 5, carrying the lamps. The end 19 of a spring-pressed plunger 18 works in the bore 14 and the plunger is connected by a recess 22 and a pin 33 with a spindle 25, to the upper end of which is secured the plate 27, Fig. 4, provided with a lamp socket 28. Each member 12 is rocked in bearings 9, 10 for dipping its lamp, it having a semi-circular recess 35 forming abutments for pistons 38, 39, Fig. 7, in cylinders 40, 41 communicating through flexible pipes (44, 46 or 45, 47) with two pairs of cylinders t, v or u, w in a fitting s, Fig. 2, clamped to the steering column q. The pistons 2 are adapted to be displaced by pusher plates z, z<1> carried by a slidable rod y operated by a hand-lever 6. All the cylinders and pipes are filled with oil. To effect swivelling of both lamps simultaneously, two cylinders are provided on each side of the lever m as in the dipping device and the plunger 18 is acted upon at both ends by fluid pressure, the spring 21 being dispensed with. One of the, lamps may be swivelled automatically towards the near side of the road during the dipping movement as by means of a lug 49 connected by a rod 50 to an eyelet 51 on the bearing 9.
