Title: Improvements in aeroplane wing structures
IPC: B64C3/00
Filed: 1933-03-01
Abstract: 417,178. Aeroplane wings. WELMAN, F. S., 55, Pinnacle Hill North, and LEVELL, A., 31, Chieveley Road, both in Bexley Heath, Kent. March 1, 1933, No. 6175. [Class 4.] In an aeroplane wing comprising a main spar, transverse ribs attached to the spar, the wing frame is braced by tension-compression members g extending somewhat spirally around and along the wing to provide a continuous and uninterrupted reinforcement for withstanding drag and torsion loads. As shown the wing comprises a main spar a and front and rear longitudinals f, f converging from an inner root rib b to a smaller outer rib c. Intermediate girder longitudinals d are spaced out parallel to the spar a so that only the central members are connected to the rib c and a number of transverse cantilever ribs e divide the wing into bays. Diagonal strips g, of channel section, are placed over the longitudinal members and are secured thereto by engaging in cut away portion g' of the flanges or by splayed parts g<2> of the flanges. The diagonals g take compression and tension loads so that torsional &c. loading of the wing is distributed between all the bracing strips simultaneously. The diagonals need not cross over each other in the bays but may be terminated at the spar by gusset plates &c. Rolled strips or tubes h may be attached to the longitudinals for supporting a fabric covering. Some of the members d may be removed near the root rib b to form a luggage &c. receptacle. The members h adjoining the rib b may be extended beyond f to meet the adjacent trailing edge, the aileron being hinged at the rear ends of two of the outermost cantilever ribs e. The front ends of the strips h may be continued past the front of longitudinal f to the leading edge which may comprise a semicircular rolled strip through which the aileron controls may pass.

Abstract: <PICT:0368973/IV/1> Yarn in the form of wound packages is dyed by mounting the packages A in a tank 10 on hollow perforated spindles the ends 33 of which communicate with a reciprocating pump 11, and thus submitting the yarn to the action of the dye flowing alternately inwardly and outwardly through the packages, while ensuring that the quantity of liquid flowing outwardly is greater than that flowing inwardly, for example, by the provision of a byepass pipe 17 connecting the tank 10 and the pump 11, and containing a check valve 20 to prevent flow from the pump to the tank therethrough. Two tanks are provided for use alternately, each being connected to the pump 11 by pipes 14 leading from the spindles 33 to a main branched conduit 13, each branch of which has a cut-off valve 28. Each branch 25 of the byepass pipe 17 is also provided with a cut-off valve 26, both pairs of valves 26, 28 being operated by common levers 29, 30.  A regulating valve 19 is also provided in the byepass pipe 17, and should be so adjusted that no air enters the cylinder of the pump 11 on the upstroke of the piston 21. Each tank is equipped with an emptying pipe 31 controlled by a valve 32.  The upper ends of the cores of the yarn packages are closed by plugs 34 mounted by means of springs 35 on a frame 36, which is hinged at one end of the upper edge of the tank and fastened by a clamp at the other.  The quantity of liquid above the tops of the yarn packages A is less than the capacity of the pump 11.

Abstract: 565,850. Dynamo-electric machines ; differential gearing. BRADBURY, F. April 28, 1943, No. 6737. [Class 35] An electrically-operated differential mechanism has sun-wheels 2, Figs. 1 and 2, driven in opposite directions and at different speeds by two synchronous motors comprising rotors 9 and stator stampings 10, the energizing coil 14 of which is supplied with current from a time-controlled-frequency source. The sun-wheels drive a planet-wheel 3 carried by a block 5 secured to the driven shaft 1. Different synchronous speeds of the two motors may be obtained by the use of rotors or stators having different numbers of poles, or by providing a separate energizing coil for each motor and employing energizing currents of different frequencies for the two coils. Fig. 3 shows a construction wherein each motor has a separate energizing coil 33 and wherein the differential gearing comprises spur-wheels 22 driven by rotors 25 and meshing with coacting pinions 23 mounted in a cage formed by plates 26 carried by a spider 29 secured to the driven shaft 24.

Title: Reinforced bands
IPC: B29C65/00
Filed: 1973-02-12
Abstract: 1461767 Seaming non-metallic sheet material; laminates IMPERIAL CHEMICAL INDUSTRIES Ltd 4 Feb 1974 [12 Feb 1973] 6795/73 Headings B5K and B5N A transversely reinforced band of thermoplastic organic material is produced by treating an edge of at least two superimposed sections of a band of thermoplastic organic material, which includes longitudinally extending fibre or filamentary yarn reinforcements the axes of which are parallel to the treated edge, to cause localized adherence at this edge, and moving the sections into one plane about the adhered edge, i.e. using this edge as a hinge. The sections of a length equal to the required width of the transversely reinforced band are cut from the longitudinally reinforced band. Cutting may be effected so that the transverse reinforcements will lie either at a right or an obtuse angle to the longitudinal edge of the completed band. The treatment to effect adherence at one edge of two superimposed sections may be effected by an electrically-heated metal strip or heated rotary or guillotine knife which simultaneously trims the edges. The blade surface may be treated or coated with silicone or polytetrafluoroethylene to prevent the thermoplastic material sticking thereto. In an example, a plurality of cut sections are superimposed one on the other in a pile, alternate junctions at the edge which is to be heated being interleaved with a strip of non-thermoplastic or non-stick material, e.g. cellulose paper, to prevent adhesion at these junctions. The treated pile is opened out to form the band. Specified thermoplastic organic materials are low and high density polyethylene, polyvinyl chloride, polyurethane based upon a polyester or polyether, a polyester, a polyamide, synthetic rubber and natural rubber in the partially or unvulcanized state. These materials may be in solid or cellular forms. Specified reinforcements are staple fibre or filamentary yarns of a polyester, a polyamide, glass, cotton, and regenerated or chemically modified cellulose. A composite band having both transverse and longitudinal fibrous reinforcements is made by laminating together a transversely reinforced band of the present invention and a band of thermoplastic organic material having longitudinal fibrous reinforcements.
