IPC: F02C7/047
Filed: 1948-12-09
Abstract: 663,194. Centrifugal and axial-flow compressors; gas turbine plant. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. March 9, 1950 [Dec. 9, 1948], No. 31926/48. Classes 110(i) and 110(iii) [Also in Group II] A rotating screen extends across the path of the air flowing through the air intake of a compressor, and throws off centrifugally any extraneous matter deposited on the screen by the air. A rotating screen at the intake to the compressor of an aircraft gas turbine engine comprises radial wires 6 carried by the centrifugal impeller 3. Ice or moisture picked up by the wires is thrown off centrifugally into a trough which is drained by a pipe 10 or mechanically scavenged. Hot gas or air may be supplied to the trough to melt the ice and facilitate its removal. A liquid may be supplied by way of passages 11, 12, to wet the wires and may be sticky to entrap dust and instead or in addition be a de-icing fluid. The surface area of the screen may be increased by intermeshing nylon threads with the wires 6. The wires may be round, streamlined or of aerofoil section and may be in two rows, staggered in relation to each other. Vibration of the wires, induced by aerodynamic effects, may be used to dislodge the ice or other fouling matter. The compressor may be of the axial-flow type, and there may be a reduction' gearing between the compressor and the screen. The screen may sweep a larger area than required for the normal passage of the air to allow for the inner part becoming blocked. Where the flow at inlet is radially inwards, the screen may be frusto-conical or cylindrical.

Title: Improvements relating to circular rib knitting machines and methods of operating the same
IPC: D04B9/06
Filed: 1939-12-11
Abstract: 533,889. Knitting-machines. HADDAN, R. (Scott & Williams, Inc.). Dec. 11, 1939, No. 31955. [Class 74 (ii)] A cylinder-and-dial machine for making ribbed instep hosiery and having dial needles with high and low knitting butts is provided with means for transferring loops from the lowbutted dial needles while knitting is continued on the high-butted dial needles. In one form, as applied to a machine having two-part dial needles as described in Specification 186,405, [Class 74 (ii)], the usual transfer cams 16, 17 are provided together with an additional independently movable withdrawing cam 20 operative upon the butts n<SP>10</SP> of the needle hooks. The cam 20 in operative position engages only the high butts n<SP>10</SP> on the hooks of the instep needles so that these hooks are withdrawn prematurely so that the loops are not transferred to the corresponding cylinder needles. The hooks of the heel dial needles are unaffected by the cam 20 and are actuated by the cam 17 to transfer their loops. In a machine employing latch needles in the dial, transfer cams 24, 25, 26 are provided of which cam 25 is movable independently of the other two. Cams 24, 26 can engage both high and low butted dial needles, and cam 25 engages the high butts only. Cam 24 pushes all of the needles out not quite far enough to transfer their loops, whereupon the high-butted needles are retracted by cam 25. The low-butted needles pass on to the cam 26 which moves them outwardly sufficiently to transfer their loops. Specifications 196,124 and 197,665, [both in Class 74 (ii)], also are referred to.

Abstract: 852,897. Nuclear fusion reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 9, 1958 [Oct. 15, 1957], No. 32246/57. Class 39(4). A gas discharge apparatus of the type wherein a pulsed high-current ring discharge is induced in gas in a torus having thick electrically conducting walls, the discharge forming the single turn secondary winding of a pulse transformer having a primary winding, is characterised in that a field winding is provided on the torus wall adapted when energised in synchromism with the primary winding to produce a transverse magnetic field, within the torus substantially normal to the median plane of the torus at the median plane of the torus whereby the position of the equilibrium axis of the discharge channel may be controlled after the eddy currents initially induced in the walls by the discharge current have decayed. The field winding may be constituted by the primary winding which is wound eccentrically round the torus with its maximum winding depth at the extreme outside circumference, Fig. 1 (not shown), this gives a resultant uniform magnetic field across the bore of the torus. It is preferred to produce a betatron type of field by providing a field winding, as shown in Fig. 2, comprising two adjoining portions 7 and 8 having crescent-shaped cross-sections and equal numbers of turns, the two portions being connected in series opposition and pulsed in synchronism with the primary winding.

Patent GB-447604-A (GB)
Title: Suspension of road-vehicles
IPC: B60G3/26
Filed: 1935-11-25
Abstract: 447,604. Vehicle spring - suspensions. M. G. CAR CO., Ltd., RENWICK, W. S., and ENEVER, A. S., Abingdon-on-Thames. Nov. 25, 1935, No. 32598. [Class 108 (ii)] A wheel mounting forming part of a suspension system for a road vehicle is so constructed that the wheel has two principal movements, one which is substantially free from lateral tyre scrub and occurring when the wheel moves similarly to the wheel on the opposite side, and a second which is roll-resistant and occurring when the wheel rises or falls independently of or more than the opposite wheel. As shown in Fig. 1 the wheel brackets 12 are hinged to the outer ends of upper and lower wishbone links 14, 15 which are pivotally mounted at their inner ends on shafts 16, 17 carried by levers 25 pivoted at 26 to the chassis frame. The lower links 15 are shackled to arms 18 fast on torsion bars 19 rigidly secured at their remote ends to the frame. In order to produce the second wheel movement referred to above a transverse bar 23 connects a downwardly-extending crank-arm 22 on the upper link 14 of the right-hand wheel-mounting with an upwardly-extending crank 24 on the lower link 15 of the left-hand mounting so that when, for example, the left-hand wheel moves upwardly relatively to the chassis and to the other wheel, the rod 23 being held by the crank 22 causes the left-hand mounting to pivot about the pivots 26 against the action of the torsion spring 19, the wheel thus inclining inwardly. In a modification, Fig. 3, (not shown), the torsion springs are replaced by leaf springs rigidly secured to the chassis frame and shackled at their free ends with one of the wishbone links, and by appropriate arrangement of the angle between each link and shackle, forces tending to force the bottoms of both wheels inwardly or outwardly together, may be resisted. In the construction shown in Fig. 4, the wheels are supported by horizontal forwardly-extending arms 30 fast on rigid shafts 31 connected by universal joints 32 with a rigid shaft 33 journalled in a box 35 rigid with the chassis frame. The upper face of an arm 36 fast on the shaft 34 engages a coiled spring (not shown) interposed below a part rigid with the chassis frame, which spring resists simultaneous similar movements of both wheels. The shafts 31 are journalled in swinging brackets 38 fixed to shafts 39 to which are rigidly secured arms 41 engaged by coiled springs (not shown) so that movement of either wheel relatively to the other causes the corresponding bracket 38 to swing in its journals 40 against the action of the coiled spring bearing on the arm 41. In a modification the coiled springs are replaced by leaf springs. The Specification also includes a diagrammatic representation of the relative positions of the various parts of the wheelmounting when the wheel occupies various positions. Specification 451,105 is referred to.

Abstract: 1,043,880. Pinch roller actuation. TAIKO DENKI SEISAKUSHO KABUSHIKI KAISHA. Aug. 12, 1964 [Aug. 15, 1963], No. 32821/64. Heading G5R. A pinch roller 3 is mounted on a support 4 pivoted at 6 and provided with a pivot pin 7 on which are pivoted the arms of a U-shaped operating arm 8 which co-operates with an operating lever 10, the arrangement being such that repeated movement of the lever 10 in the direction of arrow 14 results in alternate engagement and disengagement of the pinch roller. When the end of lever 10 is moved an inclined end 10a of the lever engages the upper end of the operating arm 8 and a spring 9 acts on the centre of arm 8, thereby producing a turning moment which causes the support 4 to rotate and allows the roller 3 to pass through an aperture 13 in a sub-chassis la, the support 4 then lying in a stable horizontal position. After the operation the lever 10 is returned by its spring 12, and a further operation of the lever causes its lower end to engage the lower end of arm 8 so that a turning moment is produced which returns the support 4 to its vertical operative position. In a modification, Fig. 2 (not shown), the end of lever 10 which engages arm 8 is U-shaped, alternate arms of the U engaging the upper and lower end of the arm 8 with alternate movements of the lever 10. The device may be used in a magazine type tape recorder.
