Title: Improvements in and relating to stockings and their manufacture
IPC: D04B9/46
Filed: 1945-04-27
Abstract: 640,634. Knitting. ROBOTTOM, F. H. April 27, 1945, No. 10599. [Class 74 (ii)] The heel of a stocking blank produced on a circular machine is knitted as a band 9 having selvedged edges 10. The band 9 is formed continuous with the leg portion by reciprocatory knitting on a group of heel needles, while the instep needles are inactive. The needle at each edge of the group of heel needles knits only at every alternate course and is raised to a loop holding position during the knitting of the intermediate courses so that the selvedge loops extend over two courses. Rotary knitting is then continued to form the foot portion, which is united to the heel portion at the foot bottom 12. To form the stocking the blank is cut and seamed, the heel portion being severed from the foot bottom 12 at 11-13 and the selvedge edges 11-11<SP>1</SP> seamed thereto, and the severed edges 11<SP>1</SP>-13<SP>1</SP> of the heel are seamed together. The toe pouch may be formed by cutting two tapered gussets 18 from the tube and seaming the edges together. Specification 640,342 is referred to. Reference has been directed by the Comptroller to Specification 413,279.

[Class 4] An aircraft having means for influencing the airflow about the wing to act as a brake has means whereby, when the retarding device is set in the operative position, the transmission members of the aileron control are adjusted to restrict or prevent the angular movement of such portions of the ailerons as lie in the wake of the retarding device. As shown, ailerons 2 are operated from a rod 5 through a bell-crank lever 6 and a link 7, further ailerons 3 disposed in the wake of adjustable flaps 1 are actuated from the shaft 5 through a rocking-shaft 8 a member 22 slidable on the shaft, links 9, 11 and a bell-crank lever 10. The link 9 is connected by a link 18 to the flap 1 so that upon adjustment of the flap through a rod 12 angular deflection of the aileron 3 is diminished or suppressed. When the flap 1 is brought into the braking position the link 9 may come into line with the pivot of the shaft 8 so that the aileron 3 is locked, preferably in a slightly depressed position. Alternatively, other locking means may be provided and the transmission to the ailerons 3 uncoupled when the flaps 1 are brought into use.

Title: Elevated trackway for transport vehicles

Filed: 1975-03-10
Abstract: 1495143 Elevated railways JOHN LAING & SON Ltd and HAWKER SIDDELEY DYNAMICS Ltd 10 March 1975 [12 March 1974] 11041/74 Heading B7L An elevated trackway comprises a longitudinal beam structure forming a central spine 12 which supports the central region of each of a succession of longitudinally spaced rib members 13, the rib members projecting laterally at both sides of the spine 12 to carry a pair of longitudinal track members 15 at their ends, and each rib member 13 being angularly adjustable in relation to the spine on assembly therewith but before being secured thereto so that different rib members can be canted in the vertical plane to different extents, thus providing for example a banked track in curved sections of the spine 12. As shown, the spine 12 is of box-shaped cross-section having apertures in its side walls through which extend the rib members 13. Each rib member comprises straight arms 14 joined by a central curved portion, the centre of curvature of the latter forming the axis about which the member may be angularly adjusted. The upper portion of the spine 12 serves as a slot conduit accommodating electric conductor rails 19, Fig. 4, beneath a slot 16 for entry of vehicle current collectors. Cladding 23 and covers 26 are provided to form a protected duct for cables 25 adjacent the spine 12 which is supported by spaced columns (11), Fig. 2, (not shown). In other forms, the conductor rails are mounted in a trough which is carried by arms extending inward from either the rib members 13 or the track rails 15. Instead of each end of the rib members carrying one rail of the same vehicle track, twin vehicle tracks may be carried one by each end of each rib member so that vehicles may travel in opposite directions. In further embodiments, the rib members may be of concrete mounted on top of a concrete spine.

Title: Improvements in or relating to fluid pressure remote control systems
IPC: B60K23/02
Filed: 1942-08-07
Abstract: 559,227. Fluid-pressure controls ; clutches, operating. BENDIX-WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. Aug. 7, 1942, No. 11079. Convention date, Oct. 9, 1941. [Class 69 (ii)] [Also in Group XXIV] A fluid-pressure control system especially adapted to operate vehicle clutches comprising clutch plates 5, 7 normally held in engagement by springs 8 and adapted to be separated by a fluid-pressure motor fed from a reservoir 35 under control of a valve 37 operated by a pedal 39 is constructed with a motor comprising a cylinder 15 fitted with a piston 19 formed with a hollow chamber 24 in which is mounted a diaphragm 26 secured between a cover plate 27 and the piston and connected to a spring-pressed member 28 by a clamping-plate 29. An aperture 25 permits passage of fluid through the piston. The member 28 is attached to a rod 30 connected by a lever 11, pin 13 and slot 14 to a shaft 10 connected to the clutch plate 7. The rod 30 passes loosely through the plate 27. In the operative position of the clutch shown the movement of the piston 19 towards the left is limited by the engagement of a shoulder 41 with a shoulder 42 on the cylinder, the cylinder being screwed to a bracket 17. The movement of the rod 30 and diaphragm 26 is limited by engagement of the member 28 with stops 43 on the piston. When the fluid pressure is connected to the cylinder 15 movement of the rod 30 sufficiently far to disengage the clutch takes place only when the pressure on the piston is great enough to overcome the pressure of spring 34 and permit the movement of the member 28 relatively to the piston. The clutch can then be operated by movement of the diaphragm 26 only, thus preventing any adverse action should the piston tend to stick in the cylinder. The valve 37 may be of the kind described in Specification 488,208.

Title: Improvements in or relating to circuit arrangements for stopping selectors driven bya number of magnets co-operating with an unwound armature and individually energisedthrough drive contacts mechanically controlled by the motion of the selector
IPC: H01H63/22
Filed: 1952-05-02
Abstract: 716,452. Automatic exchange systems. SIEMENS & HALSKE AKT.- GES. May 2, 1952 [May 5, 1951; June 19, 1951], No. 11174/52. Class 40 (4) Selectors which are individually driven by motors comprising two magnets M1, M2 alternately energized over cam-controlled contacts m1, m2 are stopped by bridging the opened cam contact through a thermionic valve so that the two magnets are energised simultaneously. Each contact may be shunted by a valve, 'Fig. 1, (not shown) or a single valve may be common to both contacts. As shown in Fig. 2, a single gas-filled valve R3 is connected to the magnets over rectifiers GL1, GL2 and is fired by positive potential applied to the grid over wiper c when the switch reaches the required outlet. With the valve conducting relay P1 pulls up and, after locking over its second winding, maintains both magnets energized independently of the valve which is disabled either by an interruption in the anode circuit or a short-circuit connection. An additional battery is located in the cathode circuit in order to maintain the magnet current at the normal level. In a modified arrangement, Fig. 3, the grid potential of a gas filled valve R5 is controlled by a valve R4 which becomes conductive only when voltage pulses ut applied to its grids G1, G2 occur simultaneously. This condition arises at a particular switch outlet, and the resulting voltage impulse in the cathode circuit of R4 triggers the valve R5 over a condenser C1 so that relay P2 pulls up and stops the switch. Due to the changed anode potential of R5 from earth to about -60 volts when the valve fires, rectifier GL5 becomes conductive and the outlet potential is lowered to a busy marking value over resistors W14, W15. A further embodiment, Fig. 4, comprises a valve R which is rendered conductive through a transformer TR by a voltage pulse and stops the switch by shunting contact m1. The switch is started by operation of relay V and the voltage impulse arises at a free outlet due to the initial difference between the outlet and wiper potentials of -60 and -5 volts respectively. Relay P2 pulls up when the switch stops, and over its second winding causes the multipled outlet taken into use to attain a busy potential of -5 volts. In a modification, Fig. 5 (not shown) an auto-transformer may be used.
