Title: Improvements in apparatus for controlling cyclic operations
Inventor: FORESTER GERALD OWEN
IPC: B64D15/14
Filed: 1959-09-02
Abstract: 914,826. Control of D.C. motors. TEDDINGTON AIRCRAFT CONTROLS Ltd. Dec. 2, 1960 [Sept. 2, 1959], No. 29965/59. Class 38 (3). [Also in Group XXXV] In a control system a control member is repeatedly movable through a first path to cause an operation, or series of operations, to be repeated at intervals and movable through a second path during said intervals, the amount of movement permitted in the second path and hence the duration of the intervals being continuously variable in dependence upon an external variable function. As shown, for a de-icing arrangement for a helicopter, the value of a resistor R1 is varied inversely as the severity of icing and is connected as shown in a bridge comprising further resistors R2-R5. The bridge is set by the potentiometer R5 and unbalance of the bridge due to increase in icing severity causes a relay A to operate which through a contact al energizes a relay B which in turn energizes a relay C. Relay C is held on by a contact c2 and a contact cl energizes a relay F to open a contact f1 and remove a short-circuit from a potentiometer R6, the total resistance of which is introduced into the bridge circuit, causing the relay A to change over contacts a1 to de-energize the relay B and energize a relay G. Closing of contact cl also energizes a winding W1 of a motor M causing clockwise rotation of cams CM1-CM3 and potentiometer R6. Cam CM1 through a switch CS1 energizes a relay J to change-over contacts j1, j2 for a brief period to energize a heating mat R7 for the tail rotor of the helicopter. Cam CM2 through a switch CS2 and operating coils SM1, SM2 pulses selector switches SS1, SS2 to energize in turn six heater mats, such as R9, R10 on the helicopter lift rotor. Cam CM3 operates a limit switch LS1 to energize a relay D which is held on by a contact d2 and contact d1 changes over to energize winding W2 to reverse the motor M. Cam CM2 then pulses switches SS1, SS2 to energize a further six rotor heater mats. When the motor M rotates the cams and the potentiometer into a second path the wiper arm of the potentiometer R6 changes the resistance inserted into the bridge. At an angle of potentiometer rotation dependent upon the icing severity and hence the value of R1 the bridge is again balanced and relay A reverts to its mid-position and breaks the hold-on circuit of relay D at contact g1 to reverse the motor M to repeat the cycle. The cycling continues with the " off "-period varying inversely with the icing severity signal. At a preset minimum degree of icing cam CM3 operates a limit switch LS3 which energizes a relay E which through contacts e2, across switch LS2, cause the motor to rotate the cams to the initial position.
