Abstract: 1341295 Gas turbine ducted fan engines H E FAHLBUSCH 19 April 1971 [18 May 1970] 22178/71 Heading F1J A subsonic multiple-spool type ducted fan jet engine has two separate inlets, one inlet serving a multi-stage compressor and the other serving a fan and comprises, an engine case containing compressor means 9, combustion means, turbine means and a primary gas nozzle 19, a rotatable multi-blade variable pitch fan 2 located directly in front of the compressor means and connected by a hollow shaft 21 to a turbine of the turbine means in the engine case, a circular section compressor inlet 3 which forms a primary flow path and which is connected with a tubular part of said fan and rotatable therewith, a mechanism 8 for varying the fan blade pitch angle, a co-axial duct 18 surrounding said fan and engine case and mounted by means of a fixed co-axial tubular fan case 7 and fixed radial stator blades 6 and consisting of a co-axial circular fan inlet located in front of said fan and which forms a co-axial secondary flow path of annular cross-section together with the compressor inlet, a series of circumferential closable slot nozzles in the front end of the fan duct and a co-axial variable geometry fan nozzle forming with the engine case a variable area annular fan nozzle. The compressor 9 is driven by a H. P. turbine and the fan 2 is driven by a L. P. turbine. The surface of the compressor inlet 3 is cambered and acts as an air diffuser and the front end of the fan inlet is cambered to produce only positive thrust components. The crosssectional area of the compressor inlet increases in an aft direction and then becomes an annular cross-section due to the presence of the hub 5. Similarly, at its forward end, the fan inlet decreases in cross-sectional area in an aft direction. The slots 4 wear the leading edge of the fan inlet prevent boundary layer separation and engine stall at high mass flow ratios and in crosswinds of up to 30 knots during taxying. The slots are closed at higher speeds and during cruise flight. During take-off and climbing, the duct nozzle is expanded and the fan blades at high pitch, so that the secondary thrust is a maximum. This secondary thrust has four components:- (a) Net thrust of the fan in the duct 18. (b) Leading edge thrust of the fan inlet 1 due to the suction pressure field at the inlet lip. (c) Thrust component due to the profile camber of the fan inlet 1. (d) Thrust component due to the profile camber of the duct nozzle 13. During cruise flight the duct nozzle is contracted and the fan blades moved to low pitch.

Abstract: 1,071,739. Fluid-pressure brakes. BENDIX CORPORATION. May 26, 1965 [June 3, 1964], No. 22383/65. Heading F2F. A fluid-pressure servomotor, particularly for operating a brake master cylinder under control of a pedal-operated control rod 42, comprises a reaction member 40 to which " feel is applied by the output member 28 via a block 30 of resilient material, seated in a counterbored recess in the power driven element 16, which under compression is extruded, firstly into the central opening of a ring 36 in the counterbore which is acted on by a prestressed spring 38, and 'subsequently into the whole of the area of the counterbore when pressure is sufficient to compress spring 38. This gives two stages of " feel," so avoiding sudden onset of " feel " as the brakes are applied. The element 16 is of plastic material and, in addition to supporting the inner edge 66 of the rolling type diaphragm 68, whose outer end is clamped between pressed steel shells 12, 14 of the housing, it provides a valve chamber 18 which is connected by passages 20, 22 to the vacuum (or atmosphere) and power chambers 72, 74, the latter being fed with air at atmospheric pressure (or compressed air) by poppet-cum-slide valve 44 integral with reaction member 40. As the latter is moved forwardly by the control rod 42 it first disengages a seat 46 and blocks communication between passages 20 and 22, then uncovers an opening in the wall of chamber 18 to allow flow of air from inlet chamber 86 via passage 22 to chamber 74. An extension tube 52 of element 16, which provides the inlet chamber, is guided in a sealed apertured plate 58 closing the rear end of shell 14, the forward end of shell 12 being closed by a seal 80 surrounding the output member 28.
