Patent GB-524645-A (GB)
Title: Improvements in means for regulating internal combustion engines of aircraft
IPC: F02D9/00
Filed: 1939-02-02
Abstract: 524,645. Regulating. BAYERISCHE MOTOREN WERKE AKT. GES. Feb. 2, 1939, No. 3544. Convention date, Feb. 3, 1938. [Class 7 (vi)] In aircraft engines having an engine-driven blower, and also an auxiliary blower driven by an exhaust-gas turbine and brought into action only after a certain altitude is reached, the regulation of the engine above this altitude is effected by control only of the supply of the exhaust gases to the turbine. In the Figure, a control device 1, comprising a barometric capsule and a servomotor, actuates a bell crank having one arm 3 connected through a lost-motion slot 8 in a rod 4 to the throttle valve 5 controlling the inlet to the engine-driven blower, the second arm 6 of the bell crank being connected by a rod 7, with slot 11, to a lever 9 and rod 12 leading to a throttle valve controlling the exhaust. When the arm 3 moves from the position 3a to the position shown, the throttle 5 is moved to full-open position, which suffices until the predetermined altitude is reached. The further movement of the bell crank does not alter the position of the throttle 5, owing to the slot 8, but begins to close the throttle valve in the exhaust, so as to restrict the passage of the gases directly into atmosphere, and bring the turbine into action. A handcontrolled lever 15 may also be connected to the throttle 5 through a slotted rod 14, and to means for adjusting the control device 1 by means of a slotted rod 19 and arm 20. The throttle 5 may be divided into two parts 5a, 5b, with the inner part connected to the handactuated rod 14, and the outer annular part connected to the rod 4.

Filed: 1920-08-24
Abstract: 176,302. White, A. E., (Rector Carbureter Co., Inc.). Aug. 24, 1920. Vaporizers, external.-Fuel to be vaporized enters an annular chamber 31, and passes by two pipes 81 to a flat chamber 76; a trapped outlet from the chamber connects with the pipe 80, which passes through the centre of the heating- chamber and forms a final heating-chamber. Projections 33 on the inner wall of the chamber 31 conduct heat to the walls. Fuel for the burner is led to the annular vaporizing chamber 47, the vapour passing through the T-shaped pipe 52 to two inclined nozzles. At starting, air for the burners is admitted through a ring of ports 37 opened by the hand-actuated valve 86. Normally a fan supplies the air for the burner through the pipe 41 and four outlets 40; baffles 54 on the chamber 47 prevent a free flow of air from these outlets. The burner is kept alight by a sparking- plug 73, which may be in series with the plug on the engine cylinder. The products of combustion, after impinging on the chamber 47, pass over the pipe 80 and through the chamber formed inside the annular chamber 31; part of these products escape through holes 88 in the top of cover 89 and part pass outside the chamber 31, escaping at the bottom 87. The vaporized fuel for the engine passes to a carburettor 15. A single fuel-pump supplies the fuel to be vaporized and the burner.

Title: A duplicator using hectographic mirror script originals
IPC: B41L11/08
Filed: 1954-02-08
Abstract: 745,982. Duplicating machines. RENAUER, A. Feb. 8, 1954 [Dec. 11, 1953], No. 3565/54. Addition to 727,008. Class 100 (2). A duplicating machine as described in the parent Specification is provided with means for feeding a mirror-script original over the flat bed of the machine so that selected portions of it may be exposed for printing. An apertured sheet may be provided overlying the original, the selected portion then being exposed through the aperture. The overlying sheet is also provided with a mirror-script text which may comprise a constant heading part, whereas the exposed portion of the underlying original provides the variable part of the matter to be printed. The base 1 of the machine is hollow and has an upper plate 2 serving as the bed on which the mirror script original 3 is placed. The end of the original passes through a transverse slot 6 in the plate and is gripped between rollers 7 and 8. Roller 7 is mounted on an axially displaceable spindle 18 and its movement is frictionally damped by a brake-band 23a. A lever 20 at one end of the roller 7 is, in one axial position of the spindle 18, coupled to the roller through a one-way clutch and spring loaded to an initial position. Actuation of the lever thereby rotates the roller 7 in steps, e.g. steps of one line's space. The stroke of the lever is adjustable by a stop screw 36. In the other position of the spindle the roller 7 is freely rotatable in either direction by means of a handle 22 provided on the other end of the spindle. The roller 8 is mounted on levers 12 pivoted at 10 and loaded by a spring 13 into engagement with the roller 7. A shaft 17 rotatable by a handle 15 carries a pair of eccentrics bearing on the free ends of levers 12 so that on actuation of the handle 15 the rollers 8 are lifted to release the original 3. In the normal position of handle 15 the original is gripped and operation of lever 20 then causes it to move in steps over the bed. The carriage 32 is adapted to carry the impression roller 33, moistening means and feeding-tray over the bed to take a copy of the originals thereon as described in the parent Specification. A comb-shaped stop 39 limits the extent of introduction of the copy sheet and the guide 34a for separating the printed copy sheet from the original is likewise combed to engage with the edge of the stop. A spring strip 40 clamped under the edge of the stop 39 is adapted to retain the overlying master sheet. Materials for use in the duplicating process, e.g. moistening liquid, may be accommodated inside the hollow base 1. The reservoir for the moistening liquid associated with the moistening means on the carriage may be transparent so that the level can be seen and elastic so that the moistening felt can readily be saturated by deforming the reservoir.
