Inventor: FORD LOUIS CHARLES
IPC: E04C3/09
Filed: 1917-05-05
Abstract: 115,466. Ford, L. C. May 5, 1917. Framework; planes and the like, construction of.-Girders, beams, spars, ribs, and other rigid structural members are formed from tubes or other hollow bodies by cutting and bending certain portions so that box girders with cross braces or ties are produced. Such girders are applicable for the frames of the wings of aircraft. The girder shown in Fig. 3 is formed by cutting the tube shown in Fig. 1 along the full lines and bending the cut portions along the dotted lines. The cuts 1 for the diagonals 7 on opposite sides are inclined in opposite directions. The flanges 4 of the opposite vertical members 5 may abut or be overlapped and secured together. Bent portions 8 constitute flanges for the booms and may be beaded, ranged, or fluted, or be folded to form tubular booms. Diagonal ties 11, 12 are bent from the top and bottom walls of the tubes. In the modification shown in Fig. 5, the flanges to the parts 5, 7 are omitted and the tube strengthened transversely by strips 14, 14<a> bent from the diagonals 7 and secured to the opposite diagonals 7 and cross braces 11. Two or more tubes may be connected, as shown for example in Fig. 6, by means of the bent portions 5, 7 which may be flat or convex in cross section, and the remaining walls or the tubes may be bent to form a triangular section. In another modification, one tube A<4>, Fig. 9, is secured inside the other tube A' by means of the bent portions a<3>, a<4>, and the top and bottom walls may be similarly connected. The tubular blanks may be rectangular as shown, or circular, triangular, or stream line in section; the shape of the cross section may vary along the length, and the tubes may be twisted or bent longitudinally and be closed at one or both ends. Sheet metal blanks may be cut, stamped, and fluted, and then be formed into tubes or other hollow bodies having the cross braces described above.

Title: Improvements relating to the propulsion of aircraft
IPC: F02K3/12
Filed: 1936-03-04
Abstract: 471,368. Propelling aircraft by fluid reaction. WHITTLE, F. March 4, 1936, No. 6505. [Class 4] In a fluid reaction propulsion system for aircraft, the output from an air compressor is divided into two streams, a first stream which is passed out through a propulsion nozzle and a second stream which supplies an internal combustion engine, the compressor being driven by a gas turbine supplied wholly or partly by the effluent gas from the engine. In one form, Fig. 1, twin nacelles 52 are provided each having at its mouth a compressor 50 and a jet 52a at its trailing end. Intermediate the two nacelles is arranged a multi-stage compressor of the kind described in Specification 456,976, [Group XXVI], the outlet of which is led to the delivery chamber 60 of a turbine driving the compressor shaft 61, a combustion chamber being disposed in the passage indicated by arrow 59. The combustion effluent expands through the vanes of turbine rotor 62 and passes to the intake of a turbine 55 driving compressor 50. In another form, Fig. 2, a compression ignition engine 34 drives a centrifugal compressor 35 supplying part of its air output to the engine and the remainder to a turbine 33 driving a compressor 31. The exhaust products of engine 34 discharge into the intake of turbine 33 and the effluent gases from the latter discharge into the atmosphere through a rearwardly facing outlet 39. The apparatus described mav derive some or all of the intake air from the boundary layer at any part of the aircraft structure. Specification 456,980 also is referred to.

Filed: 1951-03-20
Abstract: 682,433. Cable sheaths. TOMLINS, F. C. (Western Electric Co., Inc.). March 20, 1951, No. 6645/51. Class 36. A cable sheath comprises an inner screening layer of highly-conductive metal of approximately the same circumference as the cable core, and an outer layer of solderable metal applied with overlapping edges soldered together. The cable core 1 surrounded by paper insulation 2 is enclosed in an aluminium sheath 3 formed by longitudinally folding a corrugated strip so that the edges do not quite meet. A tinned corrugated steel strip 5 is then folded longitudinally over sheath 3 so that the edges overlap. These overlapping edges are soldered together to provide a hermetically-sealed sheath. An outer polythene sheath is then applied as by extrusion, the steel sheath being first covered with a thermoplastic cement which fills in the depressions of the corrugations and bonds the polythene to the metal.

Title: Improvements in or relating to thermionic valve amplifiers
IPC: H03F3/52
Filed: 1937-03-06
Abstract: 496,872. Valve amplifying circuits. WHITE, E. L. C., and HARDWICK, J. March 6, 1937, No. 6685. [Class 40 (v)] In a single-stage amplifier designed to produce no reversal of phase, particularly for television signals, the signals are applied across a resistance 6 which is large compared with the reciprocal of the mutual conductance of the valve, the resistance being connected in series in the anode circuit and between the cathode and grid. The grid is connected effectively to earth, e.g. through a bias battery 4, and the output is taken from an impedance 16 in the anode circuit. The input impedance is low and is matched to the source, if necessary, by adding resistance. A battery 7 opposes the voltage drop in resistance 6 so that normally there is no difference of potential between input terminals 1, 2. In a modification, Fig. 2, the grid is connected to earth through a condenser 11, and a resistance 12 provides a direct-current path between grid and cathode, resistance 14 providing the grid bias. Condensers 10, 13 are connected as shown and an inductance 17 and resistance 18 are connected in series across the input terminals to maintain the input impedance constant. The invention may be applied to amplifiers joined by a short length of cable, the two valves at the ends of the cable being fed from a common high-tension source and operating in push-pull. Specification 482,740 is referred to.

March 3, 1930, No. 6981. Convention date, March 22, 1929. [Class 60.] In a machine for grinding the teeth of a gear wheel by an abrasive worm, means are provided for shaping and turning the grinding-worm whilst in position on the machine. The machine consists of a base 1 upon which are standards 2, 3 supporting a bracket 5 carrying, on a spindle 4, the grinding- worm S, the spindle being driven through an electromagnetic clutch 7 and belt gearing 8, 9, 10 from an electric motor 6 ; the worm also may be driven slowly during trueing in a reversed direction, by worm gearing from a motor 11, and the worm spindle is adjustable with the bracket 5 to allow for the pitch angle of the worm. The gear wheel Z to be ground is driven from the spindle 4 through worm gearing, a shaft 15, gearing 16, a shaft 17, a shaft 20, and worm gearing 21, 22, and is reciprocated axially by a carriage 27 movable on a standard 26 by a screw 34 driven by a liquid motor 31 fed from a pump 30, which is driven from the shaft 20 ; the direction of the motor is reversed, to reverse the motion of the carriage, by a reversing device 35 actuated by the carriage to move a reversing valve 36 and also to give the carriage 25, upon which the standard 26 is mounted, a movement to feed the work to the grinding-worm. The feed movement is brought about through a ratchet wheel 44 and a pawl 45, which actuate, through gearing, a screwed shaft 40 ; fine and coarse hand actuation are provided for by wheels 41, 39. The gear wheel also may be adjusted rotationally by a hand-wheel 38 and worm gearing. The grinding- worm is trued by abrasive wheels 51, 53 carried by a slide 48 adjustable transversely on a slide 47 movable on the bracket 5 parallel to the axis of the worm by a screw 67 driven, through gearing 66 and worm gearing, from the shaft 15. The wheels are driven, through flexible and extensible shafts 60, 61, belt gearing, and a clutch from the motor 6 ; the wheel 51 trims the flanks of the worm teeth and is angularly adjustable to suit the teeth, and the wheel 53 trims the periphery of the worm teeth. The wheels 51, 53 are trued respectively by diamonds 54, 53<1>, that 54 for the wheel 53 being adjustable to suit the profile of the wheel. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a profiling roll for roughing out the thread of the worm, and means for supplying cooling water comprising a perforated device extending the full length of the worm, the water being sprayed under high pressure; or the water may be supplied under pressure to the interior of the worm to feed outwards by centrifugal force. The various movements of the machine may be interlocked, and oblique teeth may be ground. This subject-matter does not appear in the Specification as accepted.
