Filed: 1924-08-28
Abstract: 240,980. Crabtree, J. A. Aug. 28, 1924. Switches, quick-action; flexible pull actuation.-A pull or push switch of the kind in which similar movements of the operating member, in the same direction, alternately put the switch on and off comprises a slotted link, which may correspond to the dolly of a quick make and break tumbler switch of the kind described in Specification 140,180, actuated at one end or other by a member which receives a rectilinear movement as by a pull chain or push rod. In the construction shown in Fig. 1 the end of a chain f is attached to a piston-like member m guided in a slotted part of a bushing i constituting the bridge of the switch. The member m has a transverse pin upon which the open ends of a U-shaped double link f<1> are pivoted the other end carrying a pin e which engages in the slots c which have enlargements d at their ends. A washer l bears frictionally upon the link f<1> under the action of a spring h and serves to move the link to the other end of the slots when the chain f is released after being pulled, ready for actuation of the switch in the opposite direction when the chain is again pulled. At the conclusion of the operating effort the stress upon the oscillating member is exerted in a line passing approximately through the fixed axis b of the operating member. In the modifications shown in Figs. 3 and 5 the end of the - chain has a member with cross-pins e<1> for engaging the slots directly attached to it and the slotted guided member is dispensed with. The spring h<1> acts between the cross-pins and the bridge g<4> or an oscillating member q fitting in the bridge.

Title: Improvements in or relating to altitude control and indicating systems for aircraft
Inventor: MAJENDIE ALASTAIR MICHAEL ADAI
IPC: G05D1/04
Filed: 1957-06-27
Abstract: 841,489. Automatic control systems for aircraft. SMITH & SONS (ENGLAND) Ltd., S. Sept. 29, 1958 [June 27, 1957], No. 20349/57. Class 38 (4). The difference between a signal representing the altitude indicated by an indicator and a signal representing the actual altitude of an aircraft can, by the operation of a switch, either control a servo system operating the indicator or control the altitude of the aircraft, the indicator serving to set the desired altitude in the latter case. In Fig. 1, the altitude of an aircraft is automatically maintained at a desired value by a temperaturecompensated altitude responsive bellows 1 adjusting a pivoted armature 4 relative to the stator 5 of an E-type pick-off signals from which are applied to an automatic pilot 68 operating elevators 69. A knob 81, adjustable to set a desired rate of climb or dive which is indicated on a dial 82, is associated with a potentiometer controller 74 controlling the speed of an A.C. motor 51 which continuously adjusts, through gearing 44 and a cam 21, the relative positions of armature 4 and stator 5 of the pick-off. Feedback to controller 74 from a tachometer generator 47, driven by motor 51, ensures that the speed of motor 51 corresponds to the setting of knob 81. If automatic altitude control is disengaged by manual operation of a switch 52 the signal from the pick-off is applied through an amplifier 70 to cause motor 51 to adjust the pick-off to a null position so that the altitude is displayed on an indicator 45 driven by motor 51. Correction of the indicated altitude may be effected by manual operation of a knob 32 which adjusts a worm gear 23 longitudinally. A pin and slot device 85, 88 prevents re-engagement of automatic altitude control unless knob 81 is set for level flight. Specification 617,240 is referred to.
