Patent GB-1017176-A (GB)
Title: Control systems for propellers of tilt wing aircraft
IPC: B64C11/46
Filed: 1963-07-18
Abstract: 1,017,176. Tilt wing aircraft; variable-pitch propellers. ELECTRIC AUTO-LITE CO. July 18, 1963 [July 25, 1962], No. 28498/63. Headings B7G, B7V and B7W. A tilt-wing aeroplane has at least one thrustproducing propeller 6 mounted on the wing on  each side of the fuselage, control means including a governor sensitive the rotational speed of each propeller for varying its thrust, and a control for manually overriding the governor. As shown, there are four propellers, coupled together by a shaft 46 and each driven through a freewheel 32 by a free turbine 29 in a gas turbine engine 4. The propeller speed is limited by governors 33, and the engine power by governors 36 controllable by throttles 39. The propeller thrust is varied by axial movement of rods 66 connected by cables 62 to a lever 68 pivoted at 71 on a rod 76. Thus, longitudinal movement of the rod 76 varies the thrusts of the propellers in unison and rocking the lever 68 about the pivot 71, e.g. by a rod 73, increases the thrust on one side and decreases it on the other. The rod 76 is fixed to a piston 79 movable by hydraulic pressure under the control of the spool valve 87 connected to a governor 52 driven by the shaft 46. The setting of the governor may be varied by a control knob 91. The governor may be overridden by opening a valve 105 to allow communication between both ends of the hydraulic cylinder 78. This is done by moving a bar 106 having a ramp 109 for moving the valve 105. The bar 106 is fixed to the rod 76 and movable by a control knob 112 fixed to a spring-loaded pawl 114. The propellers are under governor control when the pawl is in the region G and under manual control in the region M, the detent 123 providing a zero thrust position. Control of the aircraft in pitch is effected by tail control nozzles connected to a duct 16 (Fig. 3, not shown) or by a tail rotor rotating in a horizontal plane.
Patent GB-485981-A (GB)
Title: Improvements in saw filing machines
IPC: B23D63/10
Filed: 1937-10-20
Abstract: 485,981. Saw-sharpening machines. BJORLING, G. W. R. Oct. 20, 1937, No. 28551. Convention date, Feb. 1. [Class 83 (iii)] In a saw-filing machine, the saw is fed by the motion of the reciprocating file through a holder, which is provided with yieldable supporting rails which rest on the back of the saw blade and press the saw teeth against guide discs disposed on either side of the file. Side frame members 2 extending from the base 1 carry at their outer ends a yoke 3 having inturned lower edges which support a pair of guides 5 for a file frame 9 which is reciprocated from the hand or power driven shaft 14 through an adjustable crank 13 and link 11. A link 18 secured to the frame 9 carries a bolt 19 terminating in spring legs 20 enclosing an inner slotted ring 22 which when the bolt is tightened is caused to grip a triangular file 23. In a modification, jaws 26 may be provided to grip a file 25 of the form shown in Fig. 5. The outer end of the file frame 9 is provided with similar gripping devices. The link 18 may be slotted to permit files of different length to be used. The file operates on the outward stroke, and is lifted from the work on the return stroke. For this purpose a roller 30 on the crank 13 coacts on the return stroke with a curved part 29 of a lever 28 pivoted at 27 and connected at 32 to the guides 5 which are pivoted at 6 to the side frames so that on the return stroke the guides 5 are tilted upwards on the pivots 6 to cause the file to traverse the path shown by arrows 33, 34 in Fig. 11. A plate 35 secured to the side frames carries an angularly adjustable yoke 38 which is pivotally connected to the saw-holding frame 39. This comprises side plates 41, 42 secured together at their corners and spaced apart sufficiently for the passage of the saw. Pairs of pressure rollers 44 serve as guides for the saw and coact with a central bar 47 carrying a socket 48 which is held up by a spring 52 and carries a pivoted rail 51 engaging the back of the saw blade 45. The saw is thus pressed upwardly against supporting discs 56 which can rotate freely as the saw is fed. By this arrangement a saw blade of the form shown in Fig. 6 may be filed, the rail 51 tilting according to the slope of the back of the saw. By adjusting a nut 53 the spring pressure may be relieved to prevent excessive pressure as the width of the saw increases. The saw holder may be adjusted to any inclined position by means of a link 59, Fig. 3. Feed of the saw is effected by adjusting the links of the file frame so that the file is inclined to its path of movement and is thus caused to feed the saw the required distance during the operative stroke.
