Abstract: 572,193. Sparking-plugs. BALLEY, R. A., and BICKLE, H. M. Feb. 2, 1944, No. 1926. [Class 7 (iv)] A sparking-plug comprises a metal shell 8, an insulator 1, in the bore 3 of which a central electrode 9 is fitted by being screwed into a threaded portion 4 intermediate in diameter between the bore 3 and a cylindrical recess 2 ; a flange 11, seating on the end wall of the recess 2, prevents the electrode being screwed down too far into the insulator. The outer end 13 of the central electrode makes contact, of a limited extent to limit transfer of heat, with a socket 12 in a section 10 of an electrode fitted inside an insulating cap 5 which has a tubular spigot 6 depending centrally from it and a depending skirt 7 of approximately spherical shape which extends closely to, or into contact with, the metal shell 8. A high-tension lead 20 is screwed into a taper threaded bore 17 in the cap 5 and the conductive core 21 is pierced by a spike 19 attached to the outer section of electrode 10 which is so fitted in the cap as to be removable therewith. The metal shell 8 has surfaces, which are, in section, the shape of a hexagon or other regular rectilineal. figure for engagement by a box spanner which permit the spanner to have limited universal movement as shown in Fig. 4, where ab is an arcuate intermediate portion and ac and bd are rectilinear portions extending substantially tangentially to the arcuate portion ab. An annular abutment 22 ensures that the spanner can be inclined at the maximum permitted angle without jamming.

Title: Self-sealing wall suitable for a fuel tank or conduit
IPC: B65D90/22
Filed: 1967-01-13
Abstract: 1,149,471. Laminates. GOODYEAR TIRE & RUBBER CO. 13 Jan., 1967 [16 Feb., 1966], No. 1953/67. Heading B5N. [Also in Divisions B2 and B7] A self-sealing wall for fuel containers and conduits adapted to seal punctures caused by projectiles comprises a rigid supporting layer of liquid impervious material, and a selfsealing layer comprising a fuel activatable swellable material backed by a tear-resistant fabric, sandwiched between two polyurethane layers. The term " fuel-activatable swellable material " means a material which will expand on contact with a liquid hydrocarbon fuel. The polyurethane is the reaction product of an organic polyisocyanate and a reactive hydrogencontaining material cured with a cross-linker and has a sufficient resiliency to stretch and permit passage of a projectile therethrough and then to contract to its original position to substantially seal the opening made by the projectile. Examples of reactive hydrogencontaining materials are polyester polyols, polyether polyols, and hydrocarbon polyols. The polyisocyanate may be toluene di-isocyanate and methylene diphenyl di-isocyanate. Crosslinkers may be monomeric polyols, organic diamines and alkyl anolamines. The polyurethanes may be applied as a reaction mixture in a solvent and the solution applied by casting, spraying, dipping, swabbing, or brushing. The polyurethane layer may be cast in place on the outside of a tank wall by use of a mould. The support may be of metal or plastics. In Fig. 1 a metal tank wall 1 is covered with a layer 2 of polyurethane, a layer 3 of fuel activatable swellable sealant material, a tear-resistant fabric layer 4 of nylon and an outer layer 5 of a polyurethane similar to the layer 2. The sealant layer 3 is made of uncured or partially cured rubber. The swelling action of the sealant layer 3 causes the portion of the sealant layer adjacent, say, a bullet hole, to swell and close any unsealed portion of openings in layers 5 and 2 caused by the passage of the bullet. In further laminated structures (Fig. 9, not shown), each of two of the layers comprising sealant and fabric are sandwiched between two layers of polyurethane (Fig. 10, not shown); three of the layers of sealant and fabric are sandwiched between two layers of polyurethane.

Abstract: 501,472. Aeroplane convertible into helicopter. HOVLAND, A. N. Jan. 24, 1938, No. 2282. [Class 4] An aeroplane of the kind in which the wings can be released for operation as a helicopter is provided with an additional non-driven rotor for the purpose of stabilizing the machine during transition from helicopter to aeroplane flight. In aeroplane flight, the rotor blade frames 2, Fig. 1, may serve as braces for wings 3. The wings 3 are secured to a cylinder 5, Fig. 4, rotatable about a column 1, one wing being mounted through the intermediary of a turntable 6. The wings carry engines 11 driving air-screws 4 through shafts and worm gearing and in the case of one wing either a reversing gear or a reversible pitch air-screw is provided. An axially movable and rotatable cylinder 8 coaxial with the cylinder 5 carries a rotor frame 2. The rotor blade surfaces may comprise telescopic elements, silk or other fabric 9 adapted to be furled on or unfurled from spools at the blade roots, or " Venetian blind " surfaces comprising slats adjustable about longitudinal axes. In order to change from helicopter flight to aeroplane flight, the pilot slows down the rotation of wings 3 and arrests the wings by operation of a non-reactive control 26 which simultaneously causes a peg 18 to move into the path of a lug 16 formed on turntable 6 so as first to change the pitch angle of the wing and then to stop rotation, causes a peg 33 to strike the operating, mechanism of reversing gear 35 associated with the air-screw drive'on the wing, and causes release of a detent 36 permitting engagement of a spring-pressed locking pin 38 in registering holes formed in sleeve 5 and column 1. The wings are locked in their transverse position by pawls which become operative when the peg 18 is operated. The control of the engine throttles is effected through a cam-member 56 which is struck once a revolution by a similar member on a lever 58 connected to the throttles. Lever 58 is maintained substantially in its deflected position by a pneumatic dashpot 59. After aeroplane flight is achieved the rotor surfaces may be furled by engagement of a lever 42 with a notch formed in a cone 43 freely rotatable on the axle 44 of the rotor and having internally of the axle a number of spools on which are wound the cables serving for the winding-in and paying-out of the fabric covering of the rotor frame. Rotation of the rotor is finally arrested by a pin 52 and when the blade frame is fully lowered, catches 10, Fig. 1, hold the frame 2 in position. The axle of the freely revolving rotor may be universally tiltable.
