Title: Improvements in or relating to large helically-wound pipes and the production thereof
IPC: F16L9/16
Filed: 1970-08-05
Abstract: 1,263,420. Making composite strip and tubes; welding by pressure and fusion. MANNESMANNROHREN WERKE G.m.b.H. 5 Aug., 1970 [3 Sept., 1969], No. 37889/70. Headings B3A and B3R. [Also in Division F2] A multilayer steel strip is helically wound to form a pipe, adjacent layers of the strip being welded together along the two longitudinal edge zones of the strip, i.e. at 3 in Fig. 10, and adjacent coils of the helically wound strip being secured by a helical weld 2 which extends over the entire thickness of the multilayer strip. The pipe diameter is between one and four metres and the thickness of the strip is at least 6 mm. Three, five or, as shown, four layers may be employed. In the case of four layers, firstly a pair of layers may be welded together in a roller seam welding machine (Fig. 2), and then this pair may be welded to a similarly welded pair (Fig. 3). Alternatively, single layers may be welded one to each side of a welded pair (Figs. 5a, 5b). The steel may be unalloyed and killed or low-alloy, e.g. manganese. Stresses along the edges of the assembled strip are relieved by inductance annealing (Fig. 7) and the edges are chamfered (Fig. 8) prior to the helical welding, Fig. 9. The weld is ultrasonically tested, Fig. 10. The individual layers at the ends of a formed pipe may be stepped (Fig. 11), welded together (Fig. 12) and chamfered (Fig. 13) before welding two such-prepared ends together (Fig. 14).

Title: Improvements in electrical control systems
IPC: G11B5/55
Filed: 1956-12-21
Abstract: 847,938. Electric correspondence control systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 21, 1956 [Dec. 28, 1955], No. 39121/56. Class 40(1). A transducer head is positioned adjacent the surface of a record medium in response to a signal derived between a tapping which moves along a current carrying strip and a tapping positioned on the strip at a point defining the required position of the transducer head, whereby the latter is brought to its required position by controlling it to bring the said signal to zero. As shown, Fig. 4, in a track selecting arrangement the strip PT made of conductive plastic material has potentials - A, +A applied across its ends and has end connections and tappings 10 to 90. Any strip length, e.g. that between tappings 50 and 60 may be selected by closing appropriate switches S, the tappings being thus extended to leads L, M, across which a further tapped resistance P1 . . . P10 is connected, the switch arm B being capable of being set to any tapping so as, in effect, to sub-divide the length between tappings 50, 60. The difference of potential between the arm B and the slider SL, attached to the transducer, operates through push-pull stages V4, V5 and V6, V7 to control clutches CL1, CL2 which cause the transducer together with the slider to move in a direction such as to reduce the difference of potential to zero. To reduce hunting the valves V6, V7 are further controlled by a differentiating circuit comprising capacitors C1, C2, C3 and valves V1, V2, V3. An embodiment is also described, Fig. 2 (not shown), including a further set of switches for further decimal subdivision. In an embodiment for locating a disc, Fig. 3, tappings on the strip PT are provided corresponding to each disc loaction. Thus the pair of reproducing heads T1, T2 is first put into the position of a record Rc and a probe PR moved along the strip until a voltmeter V records no voltage between the probe and the slider SL. A hole H or a tab TB is then provided for effecting connection at the point so determined. The strip PT is thus calibrated and can then be used in accordance with the invention for setting the transducer heads. Specification 819,789 is referred to.

Title: Improvements in variable area convergent-divergent jet engine exhaust nozzle
Inventor: BEAVERS ROBERT GERALD
IPC: F02K1/12
Filed: 1965-09-16
Abstract: 1,085,090. Jet-propulsion nozzles. GENERAL ELECTRIC CO. Sept. 16, 1965, No, 39554/65. Heading F1J. In a jet-propulsion engine, a convergentdivergent jet nozzle having a throat 17 is formed by a circumferentially-arranged series of flaps 16 each pivoted to the tailpipe 12 at 15, and a circumferentially-arranged series of flaps 40 pivotally connected at 45 to a circumferentiallyarranged series of flaps 49 each pivoted to the engine housing 10 at 51. Gas-tight seals are provided between axially-adjacent flaps and also at the hinges 45 and 51, but an annular gap 65 is left between the flaps 16 and 40. Air from the engine inlet duct passes through passage 66 between the housing 10 and tailpipe 12 and enters the jet nozzle through the gap 65 to cool the flaps 40. The size of the throat 17 is controlled by actuators 23 connected via an axially movable ring 20, links 26, bell cranks 27 and links 30, 35 to the flaps 16, 40. Actuators 56 are connected by an axially movable ring 58 and links 61 to the flaps 49, whereby the flaps 40, 49 are movable to vary the nozzle exit area 41. The position of maximum area, shown dotted, is used for supersonic flight. The gap 65, which has an ejector action on the air flowing through it, varies slightly in size according to the positions of the flaps, the size being a minimum at low ratios of exit area to throat area. Nevertheless, the air flow at low aircraft speeds exceeds that needed for cooling purposes. This excess flow reduces spillage at the air intake and the resultant aerodynamic drag, and, by increasing the mass flow through the engine, increases efficiency. A lost-motion connection between the actuators 23 and 56 is provided by links 74 each pivoted at 76 and connected at 70 to the ring 20 and at 80 to a collar 82 slidable on the ram 57 of an actuator 56. This ensures that the throat area is always smaller than the exit area. If operation of either set of actuators 23 or 56 tends to cause the ratio of throat area to exit area to approach unity, each collar 82 comes against a stop 84 thereby causing movement of the other set of actuators to prevent the ratio from exceeding the limit. The linkages between the actuators and the flaps may comprise rollers engaging cam tracks.

Title: Mould carrier
IPC: B22D17/26
Filed: 1975-09-26
Abstract: 1519834 Mould closing and locking device UPJOHN CO 26 Sept 1975 [2 Dec 1974] 39636/75 Heading B5A A device for closing and locking a mould, of particular use in forming foamed polyurethane articles, comprises a fixed lower platen 10 and an upper platen 18 movable initially bodily away from the lower platen along a straight line and then pivotable upwardly through 90 degrees to fully open the mould. The upper platen carries a guide pin 30 provided with trunnions 48 to which one arm of a two-armed main lever 22 is pivoted, the other arm of the lever being pivoted to toggle levers 20. The toggle levers are pivoted their other ends to a shoe 14 slidable under the action of a cylinder 16 (or a cam or ramp, in the case where the mould circulates on an endless path) along a horizontal guide rod 12. The main lever is pivoted intermediate its ends at 24 to the upper ends of a pair of intermediate links 26, the lower ends of which are pivoted to the frame supporting the lower platen. Also pivoted to the frame at the same point as the intermediate links are two guide levers 32 carrying at their other ends a guide bush 34 embracing the guide pin 30. A tension rod 40, one end of which slides through an abutment bush mounted upon the frame, is journalled by a trunnion 36 to the guide levers, the trunnion passing with clearance through apertures 38 in the intermediate links 38. In the mould closed position, illustrated by the solid lines in Fig. 3, the toggle levers are vertical, thus effectively locking the mould against separation, and the position of the guide levers and thus the guide bush is fixed by abutment of a buffer 44 on the end of the tension rod against the bush 40. Initial movement of the shoe 14 to the left to the position of Fig. 1 causes the main lever to pivot about its pivot 24 to raise the upper platen, the movement of the platen being linear due to the restriction imposed by the guide bush. In order that such a movement is possible the pivot 24 must be able to move to the left slightly from the position shown in Fig. 3, to that shown in Fig. 1. This in turn means that the intermediate links must be able to pivot leftwardly relative to the guide levers and this is accommodated for by the clearance between the trunnion 36 and the apertures 38 in the intermediate links. At this stage the trunnion 48 has moved into contact with the guide bush 52. Upon further leftward movement of the shoe 14 the levers 22 and 32 are pivoted in unison to the full open position shown in Fig. 6. The position of the trunnion 48 relative to the guide pin and thus the upper platen can be adjusted to alter the closing pressure. This is effected by locating a sliding pin 46 of which the trunnions 48 form part in a bore in the guide pin, the upper end of the sliding pin receiving a nut 54 which has an abutment surface engaging a similar surface on the pin. By rotating the nut the sliding pin, and thus the trunnions are moved along the guide pin.
