Abstract: 822,508. Circuits employing bi-stable magnetic elements. MULLARD Ltd. Dec. 31, 1957 [Jan. 17, 1957], No. 1794/57. Class 40 (9). [Also in Group XL (c)] In an exclusive OR gating circuit comprising magnetic cores F1, F2, each formed of a material having a rectangular hysteresis characteristic such as a ferrite, the core F1 is switched from resonant state " 1 " to the other state "0" by one or more input pulses A, B, C applied simultaneously to an input winding 11, while the core F2 is continuously biased in state "1" by a winding 22 so that two or more coincident input pulses are required to perform to " 1 " to "0" switching operation. A single input pulse A, B or C switches core F1 only, and a negative pulse is developed in output winding 13 which lowers the base potential of a p-n-p junction transistor T1, thereby producing a final output in the circuit O. When however two or more input pulses are applied together, core F2 is also switched and develops a negative pulse in an output winding 23. This pulse lowers the base potential of a p-n-p junction transistor T2 and a consequential increase in the base potential of T1 results. The final output to Rc is thus inhibited and the minority carrier storage effect in T2 ensures that transistor T1 remains cut off in the event of the input pulses terminating non-coincidently, core F1 is restored to state "1" by a reset pulse in a winding 12, and core F2 is restored automatically to this state by the bias, the resultant positive output pulse dispersing the minority carriers in T2. A diode D or a resistor Rb may be employed to reduce the loading on core F1 at this stage so as to reduce the switching time, or alternatively transistor T2 may be of the p-n-p-n type. The circuit may also be modified to give a delayed final output by reversing the direction of windings 11, 12, 21, 22 and by using an n-p-n transistor in the T2 position.

[Class 38 (iii)] An object, e.g. a gun, is moved by a motor 1 under the control of a hand wheel 9, the arrangement being such that the torque developed by the motor depends both upon the actual position of the wheel 9 and upon the acceleration imparted to the wheel when it is being adjusted from one position to another. As shown the position of the wheel 9 controls the excitation of one field 4 of a " Metadyne " 2 supplying the motor 1. Another field 10 is energised according to the back E.M.F. of the motor and according to the acceleration of the handle through a tachometer generator 13 and a transformer 16. A non-linear resistor may be shunted across the primary of the transformer 16, so as to limit the torque upon excessive acceleration of the wheel 9, and thereafter maintain a high torque after the acceleration has decreased. Modifications include the insertion of amplifiers in the tachometer-transformer circuit the use of an ordinary Ward-Leonard system; the control of the excitation of the field of a motor the armature of which is supplied from a constant voltage source ; the connection of the winding 10 across a potentiometer which can be shorted by limit switches ; the application of the control system to other motive equipment. According to the first Provisional Specification, the component due to acceleration is determined by a progressive contact device associated with an inertia mass. According to the second Provisional Specification, the torque developed by the motor is also made to depend upon the velocity of movement of the hand wheel 9.
