Title: Improvements in the construction of wings and like structures for aircraft
IPC: B64C3/18
Filed: 1931-04-28
Abstract: 377,312. Aircraft framework. BOULTON & PAUL, Ltd., Riverside Works, and NORTH, J. D., Hill House, Eaton Hill, both in Norwich. April 28, 1931, No. 12505. [Class 4.] A fitting for the attachment of struts, tension members, &c. to spars or like structural members of the type comprising a boom wholly or partly of circular or polygonal cross section and with its edges lying wholly or partly on a circular arc, is adapted to be rotated about the axis of the boom and to be fixed in any position within a given range to suit the inclination of the struts, tension members and the like. As applied to a spar comprising a circular boom a, Fig. 1, joined to another boom by a web a<1> the fitting comprises a U-shaped piece b which fits closely to the boom over an arc of 180‹ and is extended downward by parallel arms b<1>, b<2> to form seatings b<3>, b<4> for a fixing bolt c. The side edges of the fitting converge as shown in Fig. 2. Integral lugs d<1>, d<2> are formed with their sides parallel to a radius of the boom and serve for attachment of a strut. Bolt c is passed through a sleeve g of the type described in Specification 352,767 and serves to secure link plates f<1>, f<2>, connected by a yoke piece f<3> to which a tension member f is attached. The hole for bolt c is formed after the fitting has been assembled and adjusted to correct alignment with the strut and tension member. A similar fitting is described for a polygonal boom, the bolt c being located perpendicular to a diametrally opposed pair of polygonal boom faces. If the lines of force of strut and tension members are not at right-angles to the bolt c the fitting may be aligned with the strut and the tension member offset on the yoke f<3> the links f<1>, f<2> being then made stiffer. The tension members may be attached to bolt e<2> securing a strut e or to bolts in similar lugs. The bolt c in this case passes through a compression member i such as shown in Fig. 5, and which may extend for some distance along the boom. In a further modification the fitting a embraces the boom over a greater arc than 180‹ and is therefore made in two halves with a division between the lugs d<1>, d<2>. In a still further modification, Fig. 5, the fitting b is similarly shaped to the foregoing but is of sufficient internal diameter to slip over the boom on which it is located by shaped packing pieces h<1>, h<2> and by bolt c. Bracing members may be attached to the boom by angle brackets having a part j fixed to the outer side of the fitting b and having a radially extending arm j<1> to which a member such as k is fixed.

Title: Improvements in Pirn Winding Machines.
IPC: B65H54/14
Filed: 1916-09-06
Abstract: 101,417. Soc. Remontet freres. April 25, 1914, [Convention date]. Winding - machines; spindle - driving apparatus; tension arrangements. - In pirnwinding machines, the pirns are shaped by travelling disks 12 following the profile of the pirns. The disks are threaded on a screw 15 carried by arms 14, 17 hinged on a fixed bar 16. The arm 17 at its free end has an adjusting-screw 18 arranged to slide on a bar 19, and is so set that the disk 12, in its lowest position, engages the cvlindrical part 27, 28 of the pirn. At the start of the formation of the pirn, the disks 12 bear on an adjustable inclined plane 23 set parallel with the bottom part 26, 27 forming the base of the pirn. The spindles 2 have conical ends 7 abutting against springs 8, and are frictionally driven by rotary tubes 4, to which rotation is imparted by helicoidal wheels 10. Pirns are wound at both ends of the frame, and the teeth of the wheels 10 are oppositely inclined on alternate wheels, so that all the spindle ends 3 may rotate in the same direction. The thread-guide 21 is oscillated by cross-bars 31 carried by a vertically reciprocating bar 32. When the pirn is completed, a member 29, operated by hand or by the arm 17 or bar 32, disengages the cone 7 from its sleeve 4 and, by acting as a brake on the fly-wheel 9, brings the spindle to rest. The thread from a skein, bobbin, or ball is delivered to the winding-machine through tension-regulating devices, which may comprise fixed glass, enamel, or other rollers 33, Fig. 4, and ebonite or like rollers 34, 35, the latter rollers being pressed together by a spring 37.

Title: Improvements in and relating to control of earth moving machinery
IPC: E02F3/65
Filed: 1967-03-17
Abstract: 1,139,728. Earth-grading equipment. UNITED AIRCRAFT CORP. 17 March, 1967 [25 March, 1966, 28 Dec., 1966], No. 12650/67. Heading E1F. [Also in Divisions G1 and G3] The speed of travel of an earth scraping machine is maintained at a set value by comparison of the actual speed, from a tachogenerator 22, with a reference and using any error to adjust the depth of cut. The error is derived as a D.C. voltage whose magnitude and polarity controls a hydraulic or cable and winch actuator 40. In one embodiment (Fig. 3, not shown) the gain of the system is increased with increasing quantity of earth loaded by applying the error signal to a "compensator" circuit (82) responsive to a measurement of the load. The "compensator" , also adds a differential of error term to the proportional error signal. The load is in any case measured and when the bowl 12 is full an alarm is sounded and the scraper is fully raised. The load may be determined by measurement of the pressure in the lower half of the hydraulic actuator 40, (Fig. 4; not shown), or by a strain gauge in the supporting cable if used (Fig. 5 not shown), or is derived by integrating a measurement of the rate of loading, this measurement being effected by energising a depth' of cut transducer 43 connected to a skid or wheel with the output of the or another tachogenerator. This measuring system may be A.C. or D.C., the depth of cut transducer may be a linear potentiometer or movable core transformer, and the rate of loading itself displayed on an electrical instrument. The "full load" point is set as a reference signal which is automatically reduced if the machine is on a cross gradient by a damped pendulum operated potentiometer (48).

Abstract: 1309591 Cathode ray storage and display tubes; gas discharge display panels MONSANTO CO 17 March 1970 [18 March 1969] 12898/70 Heading H1D Storage tube apparatus comprises a panel including a plurality of storage cells 26 filled with ionizable gas, an electrode such as apertured electrode 30, a continuous electrode 28 on or in the panel spaced from the cells and on the opposite side thereof, and electron beam addressing means positioned to direct an electron beam selectively on to the insulator panel such as through the apertures of the apertured electrode to establish charges on the insulator surface for initiating gas discharge. A sustaining potential (e.g. D.C. or A.C. (500 V, 300 KHz)) less than that required to initiate a discharge but sufficient to maintain the discharge once initiated may be maintained across the cells, charges on plate 24 from the electron beam then precipitating gas conduction. Insulators 20, 22, 24 may be glass, 0À006 inch thick and cells 26 formed by drilling or etching, with an intercellular spacing of 0À025 inch (1600 cells/ inch<SP>2</SP>), and filled with 95% He-5% Nitrogen for example. Electrode 28 may be stannous oxide, electrode 30 of Al film, the latter being at ground or positive potential depending on gun 34 potential. Intensity modulation during scanning is effected by beam-gating grid 46. In 10<SP>5</SP> to 10<SP>7</SP> torr vacuum, plate 24 deposited charges dissipate in about 10 seconds due to positive ion bombardment and surface leakage and the decay rate may be controlled by surface treatment, e.g. provision of thin, high resistivity stannous oxide layer. Extinction of a character or all displayed information may be by termination of the A.C. voltage, or pulsing the electron beam during the required half cycle to oppose the surface charge due to A.C. source 50. Applications instanced are alpha-numeric display, storage oscilloscopes, and data display in computer time sharing scientific and educational applications. For non-visual readout, the panel need not be transparent, the above panel being adjacent a photoconductive layer between orthogonal crossed-grid transparent conductors.
