Title: Improvements in or relating to aerofoils for aeroplanes
IPC: B64C9/22
Filed: 1938-11-12
Abstract: 525,400. Controlling aircraft. ROSE, W. K. Nov. 12, 1938, No. 32986. [Class 4] Relates particularly, though not exclusively, to improvements in the form of turbine passageways extending substantially spanwise through an aerofoil as described in Specification 497,500, and consists in a construction which reduces the drag at low angles of attack. The invention is described as applied to a high wing monoplane in which each wing comprises a main supporting section 15, a nose piece 16, a trailing edge section or flap 17, an aileron 18, and a wing tip 19. According to the invention, the surfaces defining the passageways are arranged as shown so that the leading surfaces 44, 54, extend below the trailing surfaces 48, 58. The flap 17 has a concave under surface 65 and a substantially flat upper surface which, when the flap is in its normal position and the passageway is closed, lies substantially parallel to the chordline of the wing. The ailerons may have a cross-section similar to that of the flaps with the exception that the leading edges are semi-circular, the abutting wing surface also being semi-circular. The wing-tips may have the general contour indicated in Fig. 4. The nosepieces and flaps on opposite sides of the aircraft are respectively connected to shafts for simultaneous operation, universal joints being interposed in the shaft if necessary. The nose pieces are mounted on a shaft 75 adapted to be turned on operation of a hand lever 86 acting through link 85, a bell crank lever 82, 83, a link 81 and a lever arm 80. The flaps are operated through similar mechanism from a hand-lever 106. The hand-levers are provided with spring-pressed locking detents. The detent for the lever 86 may be held out of engagement with the co-operating rack to permit automatic operation of the nose pieces against the action of a spring 93. Stops limit the movement of the bell-crank levers, the arms 82, 103, of which have such relative lengths that the desired relative movements of the nose pieces and flaps may be obtained.

Title: An improved aerial bomb and method of using the same as a defence against aerial attacks
IPC: F42B12/20
Filed: 1938-11-12
Abstract: 524,979. Aerial bombs; fuzes. IMBER, J., and HEBARD, H. C. Nov. 12, 1938, No. 32995. [Class 9 (i)] A bomb, particularly intended to be dropped by fighter aircraft so as to burst in or near an enemy formation at a predetermined distance below it, consists of a light cylindrical casing 1 having end plates 2, 3 between which a charge of shrapnel is housed. A detachable nose-cap 4 is held on one end of the bomb by a pin 7 which also engages the outer end of a sleeve 10 the inner end 11 of which is closed and bears on a portion of a time fuze 12 and percussion cap 13 to retain them in operative position. The percussion cap is inserted in one end of a centre tube 14 and is connected by the fuze 12 to a detonator 15, one or more of which are housed in a corresponding number of wells 16 offset from the centre of the bomb. The other end of the bomb terminates in a fairing 17 through which extends a tube 18 carrying a set of vanes 19, this tail unit being detachably secured to the tube 14. A spring-pressed striker rod 21, extending through the tube 14 and terminating in the tail tube 18, is held in inoperative position by a lever 27 which passes along the exterior of the casing 1 from beyond the carrier loop 28 to a point between two of the vanes 19, a projection 29 on the inner side of the lever passing through a slot 30 in the tube 18 and engaging in front of a collar 31 on the rear end of the striker. Forward motion of the lever 27 is prevented by a transverse pin 32 fixed on one of the vanes 19 whilst any tendency for the lever to move outwards away from the casing 1 is prevented by a pin 33 passed through the lever 27, tube 18 and striker 21. In operation, when the bomb is released, the lever 27 is freed by withdrawal of the. pin 33 by mechanism carried by the bomb rack or operated directly from the cockpit. The striker thereupon moves under the action of its spring towards the cap 13 and the lever 27 is partially rotated around the pin 32 until it strikes the edge of the guard ring 34 surrounding the vanes 19 and thus becomes detached from the bomb. Impact of the striker with the cap 13 starts the delay-action fuze, and the bomb is exploded after falling through a predetermined distance depending on the length of the fuze.

Title: Plant for reeling rolled strip in continuous strip mills
IPC: B21C47/34
Filed: 1957-10-22
Abstract: 862,968. Rolling; winding and reeling. DEMAG A.G. Oct. 22, 1957 [Oct. 22, 1956 (2); Nov. 14, 1956], No. 32996/57. Class 83 (4). Apparatus for guiding the head of rolled strip towards reeling means includes a series of groups of driving and guiding rollers which groups come successively into position over a bed as the head of the strip reaches them and disengage the strip when the head thereof reaches the next group of rollers, so that when the head of the strip reaches a pair of rollers disposed beyond the bed and 'before the reeling means and this pair of rollers is braked, to allow the strip to be inserted in the reeling drum, strip behind this pair of rollers may accumulate in loops on the bed. The head of strip from a rolling mill passes through rollers 8, 9, driven at the speed of the strip, through swing- able guide-means 6 to opposed rollers 15 of a group of rollers 16 carried on a vertically slidable support 17. The rollers 15 of each opposed pair of the group are mounted in rocker arms 22 and are swung towards one another to engage the strip by electromagnetic means 29 operating through linkages 31, 32, the means 29 being energized after a predetermined number of revolutions of the roller 9 which actuates counting means 13 (not shown). The rollers 15 of a group are driven by an electric motor 27. As the strip head leaves the first group 16 of rollers 15 and enters between the rollers 15 of the next group 33 the electromagnetic means 29 of this group are actuated by the counting means 13 to close the pairs of rollers 15 of this group on to the strip. At the same time the rollers 15 of the group 16 are moved apart from one another to disengage the strip and the group, on the support 17, is lowered below a bed 1 by piston means 21 and linkages 19, 20. Strip then passes into group of rollers 34, and group 33 are lowered, to allow the guide means 6 to swing to loop the strip on the bed 1 behind the roller group 34. Strip then passes between rollers 2 and 3 which are immediately braked so that the head of the strip, after being trimmed by cutters 5, may be inserted into a slit of a winding drum on a reel 4 formed'by a coil pin 35 and clamping jaw 37, which jaw is then rocked by a piston 39 to clamp the strip and the reel is rotated. The group 34 of rollers 15 is lowered as the strip enters the rollers 2 to leave the bed 1 free for looping. Stripper means 41 push the wound drum on to a discharge conveyer 42. The strip is alternately fed to two reels. The rollers 15 have a slightly increasing cross-section in the direction of movement of the strip. In a modification, Fig. 7, of a looping bed 44 is subdivided by a vertically movable longitudinal wall 45 (not shown) and either three sets of groups of rollers 15 may be provided or one set movable transversely of the bed. The two outer sets may be used with the wall 45 in position and the centre set lowered or only the centre set with the outer sets lowered and the wall 45 out of position.

Filed: 1931-11-28
Abstract: 387,792. Electromagnetic switches. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London, and WRIGHT, S. R., 113, London Road, Bedford. Nov. 28, 1931, No. 33018. [Class 38 (v).] Mechanical switches with contacts reinforced electromagnetically; arc-rupturing devices; contacts.-A fixed contact 1 on an extension of the core 9 of a series holding coil 8 co-operates with a movable contact 2 and intermediate contact 3, mounted on leaf springs 4, 5. When the magnetic or other operating force is removed from the contact 2, the coil 8 maintains the contacts 2, 3 in attracted position until the zero of the cycle, when a break occurs at 6 and subsequently another occurs at 7. The contacts may be of copper, silver, or alloy, and the contact 2 is secured by means of an iron screw 10. The main operating coil may also be wound on the core 9. In a 3-phase application, Fig. 3, a closing coil 21 attracts its armature 20 which is insulatedly pivoted at 18 and connected by springs 19 to each of three levers 17 also pivoted at 18. The levers 17 thereupon rotate levers 13 about their pivots 14 so that contacts 12 are caused to engage fixed contacts 11. In opening due to de-energizing of the magnet 21, the holding coil 16 releases the lever 13 associated with one phase at the zero of the cycle, leaving the other levers 13 closed on to a single-phase circuit, which levers are subsequently released together by their coils 16, creating a double break. The contacts 12 may be carried by iron carriers 23 and may have intermediate contacts as in Fig. 1. The Provisional Specification refers to the hold-on coil as serving also as a blow-out coil.

Title: Improvements in and relating to apparatus for the dyeing and analogous treatment of textile materials
IPC: D06B5/00
Filed: 1922-12-05
Abstract: 202,569. Brandwood, J., Brandwood, T., and Brandwood, J. Dec. 5, 1922. Circulating or passing fluids through materials; cop-type.-Two kiers 3, 3<a>, which may be of the type described in Specification 551/13 for dyeing yarns wound on perforated beams 4 by forcing liquor under pressure through the beams and yarn into the kier and vice veisa, are connected by branch pipes 14, 14a and 16, 16a communicating with circulating-pipes 10, 10<a>. These lead through stop valves 19, 19<a> and regulating-valves 17, 17a, 18, 18a to the mixing-tank, with which also communicates a pump 6 connected to the circulating-pipes by a cross pipe 9 and stop valves 20, 20a. The branch pipes 16, 16a enter the lower chamber of the kiers and thence communicate with the interior of the beams; the branch pipes 14, 14a communicate with the main portions of the kiers. Valves 21 enable the kier 3 to be disconnected. By opening valves 17<a> 20, 18, 18<a>, 19, 19<a>, and 21, the liquor is pumped through the pipes 10, 14, 14<a> into the kiers, through the beams, and back through the pipes 16, 16<a>, 10<a> to the tank. By closing the valves 17a, 20 and opening the valves 17, 20a, the circulation is reversed. By closing the valves 18, 18a and opening the valves 17, 17a, 20, 20a, the liquor is circulated in the mixing-tank. Stop valves may also be provided to cut off the kier 3a.

Filed: 1958-10-17
Abstract: 852,197. Viscosimeters. KALLE, K. T. Oct. 17, 1958 [Nov. 22, 1957], No. 33239/58. Class 106 (2). [Also in Group VIII] The viscosity or concentration of a flowing liquid is indicated or controlled by apparatus comprising a vertical rotatable shaft 4 driven by a wheel 9 and on which a disc 1 is mounted, means 14 for indicating the varying speed of rotation caused by the varying viscosity and a tube 15 for directing a jet of the liquid towards the underside of the disc which is movable along the vertical axis of the shaft 4 to rest on the liquid flow under its own weight. The shaft 4 is supported in bearings 5, 6 and carries a vessel 8 open at the top to which is secured the turbine wheel 9 driven by fluid supplied through a pipe 10. The vessel 8 is surrounded by a casing 11 against which the fluid driving the turbine is thrown whence it flows to the disc 1 to prevent deposits thereon. A tubular extension 13 of the casing 11 extends into the vessel 8 and air under pressure supplied by a pipe 12 escapes through the liquid in the vessel, the surface of which forms a parabolic shape and the depth of which varies with the speed of rotation of the shaft 4, and determines the resistance to the outflow of air. Thus the pressure in the pipe 12 depends on the speed of rotation of the shaft and therefore on the viscosity of the liquid in the tube 15. The disc 1 is slidable along the axis of the shaft 4 by a key-way connection 2, 3 and an alteration of the speed of flow of the liquid in the tube 15 alters the position of the disc so that the pressure in the pipe 12 depends solely on the viscosity and does not alter the reading on the manometer 14. A rod 18 mounted in a guide 19 on a tube 17 can be adjusted vertically by a screw 20 to alter the level of the disc 1 and a screw 21 locks the rod 18 in the support 19. The pressure in the pipe 12 may guide a regulator which controls a diluting liquid supplied to the liquid to be controlled. In a modification the disc 1 may be driven by a constant-speed electric motor, the power consumption of which gives an indication of the viscosity. The apparatus may be used to control fibre suspensions of paper pulp. Specification 619,253 is referred to.

Abstract: 1,019,640. Air cushion vehicles. WESTLAND AIRCRAFT Ltd. July 15, 1964 [Aug. 23, 1963], No. 33428/63. Heading B7K. In an air cushion vehicle having flexible skirting through which air or gas under pressure is discharged to build up and maintain the ground cushion, the portion of the flexible skirting system surrounding the rear or stern of the vehicle comprises a plurality of independent flexible sections co-operating with each other and/or with longitudinal stability keel means, whereby the stiffness of the flexible skirting system is reduced locally. The vehicle 1 comprises a flexible skirting system 2. and a longitudinal stability keel 4, which may be constructed in the manner described in Specification 959,246. The system 2 comprises lateral portions, which may be inflatable and formed with nozzles for discharging a gaseous curtain, and which extend to the rear quarters of the vehicle, the stern portion of the skirting being formed by individual sections 3 which are shaped to substantially conform to the adjacent faces of the keel 4 and skirt side portions. An inflatable closure member is described to seal undesirably large gaps. The construction enables the aft portion of the skirt to deflect readily when striking waves or solid obstacles. The sections 3 may be arranged to form a gap corresponding to 6% of the periphery of the vehicle through which gas from the cushion is discharged to provide propulsive thrust.
