Title: Improvements in or relating to instinctive control for aircraft
IPC: B64C13/00
Filed: 1945-08-22
Abstract: 603,456. Controlling aircraft. FAIREY AVIATION CO., Ltd., and FORSYTH, A. G. Aug. 22, 1945, No. 21480. Convention date, Dec. 13, 1944. [Class 4] A control mechanism for aircraft having a variable-pitch propeller comprises a control lever 12 mounted for movement from a neutral position to forward and rearward positions and connected to open the throttle of the aircraft engine when moved either forwardly or rearwardly from neutral, means for effecting a change into reverse pitch when the control lever is moved rearwardly from neutral, and means for locking the control lever against movement from a rearward position towards neutral ; the actuation of means provided on the control lever for releasing it from its locking means also initiates a pitch-changing movement from reverse to fine-pitch position and thus avoids the opening of the throttle when the propeller is in reverse pitch. The pitch-changing mechanism may be as described in Specification 597,931. The control lever 12 is movable laterally in the neutral position to adjust it either for forward or for rearward movements, which turn either lever 17 or lever 16, Fig. 3, to open throttle 26, Fig. 1, by drawing rod 23 to the right. In Fig. 6 is shown on lever 12 a pawl 55 engaging with ratchet 58 to lock the lever 12 in rearward position until the pawl is disengaged by pressing down button 53 on a rod 52, the lower end of which is at the same time used to depress a button 51 for actuating a switch 50 to vary the pitch of the propeller blades towards the fine-pitch position. Switch 60 is held inoperative by spring-pressed lever 16 until that is drawn back by moving lever 12 rearwardly whereupon the switch will close a circuit to effect a change of pitch to reverse pitch. In order that the throttle opening thus obtained may be adjusted to suit the required degree of its reverse pitch the pointer 38, Fig. 2, is set to the proper reading on the dial shown, a lever 48 being thereby caused to be moved by rack-and-pinion to the dotted line position and so to provide a stop at the appropriate place for arresting the lever in its movement of opening the throttle. A switch 44 is also set by the pointer 38 to shut-off the pitchchanging mechanism at the required degree of pitch. An auxiliary control lever 65 is provided to adjust governors controlling the pitchchanging mechanism and also to close a switch for effecting a pitch change to feathering pitch. The releasing button 53 and rod 42 are automatically raised up and kept raised out of action when lever 12 passes forwardly over neutral and into a forward position.

IPC: G06F9/32
Filed: 1956-07-13
Abstract: 827,201. Circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. July 13, 1956, No. 21803/56. Class 40 (9). [Also in Group XIX] In a co-ordinate array of storage cores, means are provided to transfer intelligence from one row (or column) to another row (or column). As described, an element of intelligence is transferred from a magnetic core FC1 to a magnetic core FC2 using an auxiliary temporary storage core FC3. A first column wire threads the cores FC1, FC2 and a second column wire threads the core FC3. During a cycle of times t1-t8 the upper waveform, Fig. 1, is applied to a first row wire threading the cores FC1, FC3 and the lower waveform is applied to a second row wire threading the cores FC2, FC3. The cores being initially empty, the operations of storing a " 1 " in the core FC1 and transferring it to the core FC2 are described. To store a " 1 " in the core FC1 the waveforms of Fig. 1 are applied and at time t2 a gate G5 is opened to admit a pulse to be stored on the line IPL to set a bi-stable stage IF to the " 1 " state. During the period t3, a gate G1 is opened by the output of the stage IF to cause a unit 1W to produce a " half write " waveform, which in conjunction with the " half write " waveform on the upper row wire, causes the core FC1 to be set to its " 1 " state. The stage IF is reset during time t4. Nothing of significance occurs during times t5-t8. To transfer the stored " 1 " to the core FC2, the waveforms of Fig. 1 are again applied. In time t1, a read pulse on the upper row wire causes the stored " 1 " to be read out and set the stage 1F. During time t2, a stage 2F is set by the output of the stage IF and in t3, the output of the stage 2F causes a unit 2W to produce a " half write " waveform which in conjunction with the " half write " waveform on the upper row wire causes the " 1 " to be written into the core FC3, the stage IF being simultaneously reset. During time t4, the stage 2F is reset. The " 1 " is now stored in the core FC3. During times t5-t8, the " 1 " is read out of the core FC3 and stored in the core FC1. The invention is stated to be applicable to transferring intelligence between rows of a matrix core store. Ferroelectric capacitors may be employed instead of magnetic cores. Specification 719,288, [Group XIX], is referred to.
