Abstract: 1,072,677. Rising-hinges; door closing devices. A. R. SANCHEZ. Nov. 29, 1963 [Nov. 30, 1962; July 27, 1963], No. 47286/63. Headings E2F and E2M. A door closing device encased in a box 1 embedded in the floor comprises a door operating shaft 2 rotatably mounted by ball or roller bearings 8 in the box 1 and carrying a fixed collar 3 on which are mounted two diametrically opposed rollers 6 resting on two helical ramps 7. The rollers 6 and hence the shaft 2 and door, rise on the ramps when the door is opened and the weight of the door causing closing movement when the door is let go. Each ramp 7 is formed by two helical arcs of approximately one quarter turn each united by their upper portions but forming recesses between their lower portions as is shown in the development of the cams shown in Fig. 7. The upper bearing 8 is secured in a part 9 formed with a part annular recess 10 adapted to accommodate a projection extending upwardly from the collar 3 when the door rises. The end of the recess forms a fixed stop which limits the opening of the door. Movable stops mounted on studs 14 in the recess 10 may be used to ensure that the rollers 6 do not surmount the vertex of each ramp and thus the door returns to its closed position. On the other hand with the movable stops inoperative, the door remains open and is retained between the vertex and the fixed stop whenever the opening movement exceeds 90‹. The mechanism is located in the box 1 by means of a centering mechanism comprising adjustable bosses 17 Figs. 1, 2 (not shown) and to eliminate shocks to the mechanism when the door is opened violently against the movable or fixed stops, a shock damping device 24 Fig. 4 (not shown) is provided.

Title: Fuel distribution systems for gas turbine engines
IPC: F02C9/32
Filed: 1972-10-25
Abstract: 1406628 Gas turbine engine fuel systems GENERAL ELECTRIC CO 25 Oct 1972 [1 Nov 1971] 49217/72 Heading F1G A gas turbine engine fuel system comprises vortex valves having outlets adapted for connection to fuel injection points of an engine, and means for delivering metered fuel to the power and control inlets of each vortex valve such that at a low fuel flow-rate each valve pre-sets a high impedance and at a higher fuel flow-rate each valve pre-sets a lower impedance. A main fuel control 12 supplies metered fuel via a flow proportioner 16 and conduits 18, 20 to fuel manifolds 22, 24. At low flow-rates the proportioner 16 directs the entire flow via the conduit 18 to the manifold 22, from which it passes via conduits 28 to the tangential control inlets 36 of vortex valves 26. Each vortex valve 26 delivers fuel via a pair of outlets 40 to a pair of fuel nozzles. Under these conditions the vortex valves have a high impedance to swamp the effect of variations of head between the top and bottom of the engine. Above a predetermined rate of flow, the proportioner 16 begins to open a valve upstream of the conduit 20 and to close a valve upstream of the conduit 18. This establishes a flow-path via the manifold 24 and conduits 32 to the radial power inlets 34 of the vortex valves 26. This progressively reduces the impedance of the vortex valves to a low value. The flow proportioner 16 may be replaced by a regulator which maintains a constant pressure differential between the manifolds 22, 24.

Filed: 1974-11-14
Abstract: 1480366 Gas turbine jet engines - air intake control MESSERSCHMITT-BÍLKOW-BLOHM GmbH 14 Nov 1974 [27 Nov 1973] 49361/74 Heading F I G [ Also in Division G3] The invention relates to a method of regulating the air-flow to a propulsion unit of an aircraft, the air intake comprising a fixed ramp 1 and one or more movable ramp(s) 2,3 which is or are adjustable to match intake air-flow to engine demand. The ratio of the air-pressure above a movable ramp (PSB) to the total pressure of the external air-flow (Pt) forms a parameter (#BACT) which is compared with the required value of the parameter (#BREQ) under the prevailing flight conditions, the result of the comparison (E) being used to effect adjustment of the movable ramp or ramps. The pressure (PSB) above movable ramp 2 is sensed at 17 and the pressure (Pt) is sensed at 16, the ratio PSB/Pt being indicated at #BACT and passed to a comparator 30 to which the parameter #BREQ derived from unit 35 is also passed. The resulting difference signal is passed in parallel through a proportional and an integral device Kp and Kl/s producing a signal XREQ which is compared in a comparator 36 with the signal XACT, the resulting signal #X(i.e. XREQ-XACT) being passed to actuator 19 which controls the position of the movable ramps 2, 3. A signal #BREF is derived in the unit 31 from signals M (Mach number) derived from Pt (total pressure) divided by PS (static pressure), and α(angle of attack, sensed at 14), the signal #BREF being passed to unit 35. A signal XREF is derived from unit 32 from signals M (Mach number) and α(angle of attack), the signal XREF being compared with XACT in comparator 33 (signal XACT being the actual position of the ramps 2, 3). The difference between these two signals #X is passed to a unit 34 from which a signal ##B is derived, this signal being passed to unit 35 where it is compared with signal #BREF derived from unit 31. The resulting signal #BREQ is passed to the comparator 30 to which signal #BACT is also passed.
