Title: Improvements in and relating to pressure sealing and closure doors for aircraft fuselages
IPC: B64C1/14
Filed: 1961-06-22
Abstract: 913,454. Aircraft doors. BLACKBURN AIRCRAFT Ltd., and HAND P. G. E. Sept. 28, 1961 [June 22, 1961], No. 22720/61. Class 4. An aircraft fuselage has the rear end of its cabin or freight compartment closed by a rearwardly displaceable pivoted pressure tight door 1, and its tail end has a lower pivoted portion 2 which normally completes the external shape and in its normal position engages and holds closed the edge of the door. In Fig. 1, the pivoted tail portion 2 is movable between the normal full line position, and positions 2A, where it forms a horizontal platform, and 2B, where it forms a loading ramp, by jacks 7 (not shown). A further portion 4 of the tail is movable to position 4A by jacks 6, to provide free access when the door is fully open, in position 1A, and may then assist in holding the door open. The door is provided at its upper edge with a projection 22, Fig. 3, normally engaging a recessed part 23 on the fuselage, and the side of the door has ball-ended members (not shown) working in slots (not shown) in brackets on the fuselage, so that the door must be lifted to disengage members 22 and 23, and to lift the ball-ended members out of their slots, before the door can open. The door operating system therefore comprises a jack 8 pivoted on a torque tube 12, to swing the door about pivots on brackets 16 working in slots 17 on the fuselage, and one or more jacks 11 to raise the door, and raise the door pivots in slots 17, by arms 12, 13, on the torque tube and link 15. This lifting also enables the door to clear any obstruction, such as a roller way, on the tail portion 2. The forward edge of portion 2 has a projection 9, Fig. 3 which engages the lower edge 10 of door 1 to close it firmly. The rim of the door has an inflatable seal 19. The jack operating sequence is that jacks 7 first lower portion 2 to position 2A or 2B, jacks 11 then raise the door, and jack 8 then swings the door upwardly, in the course of which jacks 11 lower the door again, say between positions X and Y of the door. Finally portion 4 is raised by jack 6. The reverse sequence takes place during closure. An arrangement is described, Fig. 6 (not shown), in which a single jack raises, swings, and lowers the door. The gap between the fuselage and portion 2 in its normal position is faired in by a pivoted spring biased plate 20, Fig. 3.

Title: Improvements in or relating to garment pressing machines
IPC: D06F71/34
Filed: 1933-08-15
Abstract: 424,339. Ironing-presses. RICHARDSON, J. R. S., and WHITAKER, Ltd., R. G., Middle Mill, Horace Road, Portland Road, Kingston-on-Thames. Aug. 15, 1933, Nos. 22770/33 and 937/34. [Class 138 (ii)] The valve for discharging " free steam " from the head of an ironing-press which is integrally attached to the free end of a swinging beam, is actuated by mechanism carried by the beam and operated either by movement of the beam itself or by the operation of the means which cause such movement. In the form shown in Fig. 1 the valve k is opened, through a rod g and arm f, by the clockwise rotation of a bell-crank lever c about its pivot j which is carried by the beam a. Rotation of the bellcrank is effected by the engagement of a roller on one arm of the bell-crank with a stationary cam d. The pivot j is eccentrically mounted so that the valve-operating mechanism can be rendered inoperative. In the form shown in Fig. 2 the stem w of the steaming valve is operated by the engagement of a cam m on a plunger rod n with a roller t mechanically connected to the valve stem. The plunger rod is moved against the force of a spring r by fluid pressure admitted to the cylinder p through a pipe y communicating, through a reducing valve, from the press operating cylinder or from the supply thereto. The spring r controls the duration of the steaming, the valve being open for a longer period during press closing than during the opening movement. The steaming valve may also be operated by arranging for the movement of the head lever to complete electric circuits containing valveoperating solenoids.

Title: Control device for vertical landing
Inventor: ERNST GUNTHER
IPC: G05D1/06
Filed: 1955-08-08
Abstract: 776,963. Facilitating landing of aircraft. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Aug. 8, 1955 [Aug. 11, 1954], No. 22832/55. Class 40 (1). In a device for enabling an aircraft to land vertically against a controllable vertical thrust, an indication is given or a controlling action is brought about when the speed of descent and the altitude are not in conformity with a predetermined law. As shown in Fig. 4, the position of the slider of a resistor 13 forming two arms of a bridge is controlled by the altitude and that of the slider of a resistor 14 forming the other two arms is controlled by the speed of descent. The output of the bridge, which may be shown on an indicator, is zero when the speed of descent is appropriate to the altitude. In the arrangement described, however, a second bridge is formed by the resistor 13 and a resistor 20 controlled by a motor 25 for adjusting the vertical thrust and the algebraic sum of the outputs of the two bridges is amplified and drives the motor. The altimeter described comprises a weight 7, Fig. 3, which is thrown out against the exactly equal torque of a motor 4. After the weight has reached the ground, the motor keeps the cable 5 taut and the angular position of the winding drum 1 and of a nut 9 driven by a screw on the drum shaft represents the altitude. A more usual type of altimeter may, however, be used. Rate of descent may be obtained by differentiating the voltage corresponding to the altitude.
