Title: Improvements in or relating to dies
IPC: B21D37/10
Filed: 1939-01-30
Abstract: 524,409. Cupping; flanging. ARMSTRONG CORK CO. Jan. 30, 1939, No 3128. Convention date, July 13, 1938. [Class 83 (iv)] A die unit particularly for working sheet metal comprises a movable draw-ring or like in the base having direct fluid pressure below it to uniformly load it. The top dies comprise a cutting and holding down punch 8 surrounding a forming and ejecting die 10 all co-operating with bottom dies comprising a cutting-ring 36, a draw-ring 43 and a forming- die 39. The die 10 can be removed when holding back a spring pressed pin 15, a similar pin holding the lower die 39. Air pressure for ejection is supplied on top of the die 10 through passageways in a stop member 12, Fig. 8. The combined dies form a sub-press to be inserted and actuated mechanically by a main press as in Fig. 7, where, if the base 84 deflects too much, it actuates a switch 93 to stop the main ram. The dies can be easily changed for others of the same size but different shaped heads for bottle closures. A sheet fed between the dies is severed by a punch 8 acting against the ring 36. The blank is then clamped between the punch 8 and a draw ring 43 and as both move down, the disc' 3 cupped between the ejector dies 10 and former 39, air being continuously applied to the chamber 35 under the draw-ring 43, this pressure being gradually increased as drawing proceeds by the check valve 74 provided in the air line 72, which automatically limits the flow of fluid from the chamber 35 back to the source. When the punch 8 and die 10 ascend, the draw-ring 43 also ascends to normal position, air above it escaping through passageway 94. As the punch leaves the draw-ring air fed to the vacuum breaker feed 56 moves the blank awav from the top of the draw-ring 43 so that it is carried up within the punch 8 until stripper 59 removes the remaining skeleton 61 of the sheet from the punch. Air supplied to a central distributing chamber 24 and thence to chamber 11 of the ejector 10 to eject the cupped blank from within the punch 8, assisted by the spring pressed pin 20. The falling blank is blown by air jets 79, Fig. 6, to a container or conveyer. The sheet T is then moved to the right for a repeat operation. The air pressure supplied from a source S is turned on and off by a cam 65, Fig. 6, operated by the punch unit to open valve 64 supplying air through 23, 24 to the top of the sub-press, along with lubricating fluid from a pet-cock 69. Air is also supplied through pipe 70 reducing-valve 71 manually operated to vary the pressure through 45 to the draw-rings. A safety control 73 shuts down the press if the pressure drops below a predetermined minimum. A lubricating pet-cock supplies lubricant into the air pipe 45 for the lower part of the press.

Title: Improved aircraft, submarines, and other totally immersed craft or structures
IPC: B64C23/00
Filed: 1928-02-02
Abstract: 310,988. Thurston, A. P. Feb. 2, 1928. Stecring and balancing ; planes, construction of.-A wing or plane for aircraft, submarines or other totally immersed craft or structures has an alula or small plane mounted in front of or above the leading edge of the wing near each outer end to form with the leading edge a gap which is inclined upwards rearwardly, the alula being normally set at such an angle that it lies in the rising aircurrents without deflecting them materially, and means are provided for varying the inclination and amount of projection of the alula simultaneously. Means may be provided for varying the inclination of the alulas on the two sides of the machine independently of their projected position either together, or in a modification, separately, and means for projecting or retracting the alulas on the two sides of the machine in the same or opposite directions may be used. Fig. 1 shows an alula a mounted on two links r<1>, r<11> of unequal length pivoted to a bracket t on the plane, and moved by the linkage w<1>, u<1> connected to the pilot's control lever. The negative inclination of the alula increases as its distance from the plane increases. The lower ends of the links r<1>, r<11> may be mounted on pivoted levers movable by a hand wheel on the control lever so that the inclination of the alulas for a given position may be varied. Fig. 5 shows an alula that is swung away from the leading edge of the plane about its inner end and at the same time its negative inclination is increased. For this purpose an arm b is mounted in a spherical bearing at c and in another spherical bearing at d which can be moved in a slide m, Fig. 10, by a cable q. This cable also is connected to a lug on a section l of the leading edge of the plane which is pivoted at o so as to balance the drag on the alula and facilitate its movement. A lever f on the arm b is connected: by a link h to a fixed point on the plane so as to effect the turning movement of the aileron, the increase in negative inclination being greater for forward displacements from the normal position than is the decrease for rearward displacements from that position. In its rearmost position the trailing edge of the alula is preferably level with the leading edge of the plane. The cables q may be operated by the means described in Specification 180,359. Fig. 15 shows a further modification in which an alula parallel to the leading edge of the wing is mounted on arms r pivoted to brackets t at s and balanced by a pivoted section of the leading edge of the plane, similar to the section l shown in Fig. 5, to which it is connected by the linkage u, v, w. Where more than one alula is used one in front of another they are connected to balance one another. Fig. 19 shows two such alulas mounted on twoarmed levers pivoted at s. The forward alula is set at a greater negative inclination than the following alula.

Filed: 1930-01-31
Abstract: 336,525. Humphreys & Glasgow, Ltd., (Assignees of Perry, J .A.). March 2, 1929, [Convention date]. Producers.-In a carburetted water gas set, oil gas is obtained by passing separate streams of a hydrocarbon fluid through the generator and through the carburettor, the hydrocarbon fluid being cracked during passage through the heated fuel bed, and the gas withdrawn separately from that formed in the carburettor and superheater. The fuel bed 2 of the generator 1 is blown with air, and the carburettor 12 and superheater 17 heated by the blast gases. Hydrocarbon gas is admitted through inlet 6 and cracked in the fuel bed, or oil may be admitted through inlet 8, the gas obtained passing out through outlet 9. Gas or oil is simultaneously supplied by pipes 14 or 13 to the carburettor 12, and the cracked oil or oil gas passes through the superheater 17 to the outlet 22 steam being supplied through pipe 15 to assist its passage, and the resultant gas is subsequently mixed with the gas from the generator. A small amount of the re-formed gas from the fuel bed may be sent through valve 25 or 27 to carry the oil vapours through the carburettor and superheater, instead of steam from pipe 15. This may be followed by an upward passage of - hydrocarbon gas through the generator, and this gas may be led out through an outlet 28 or passed through the carburettor and superheater when it may be carburetted with oil from pipe 13. At intervals, steam is passed through the fuel bed to produce water gas from the deposited carbon unconsumed by the air blast, and this water gas may be carburetted in the usual way, and mixed with the gases previously referred to. Specification 331,138 is referred to.
