Title: Improvements in and relating to dynamo electric machines
IPC: H02K47/16
Filed: 1941-10-18
Abstract: 566,882. Dynamo-electric machines. MORRIS, D. G. O., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Oct. 18, 1941, No. 13440. [Class 35] [Also in Group XXXVII] A metadyne 1 has in series with the secondary circuit 2, 3 a compensating winding 4 which partly, wholly or over - compensates the armature reaction of the secondary current. The excitation is controlled by a variator winding 5 which is fed through an amplifier 5a with a voltage which, according to the position of change-over switch 11, 12 is either (a) the difference between a control voltage supplied by potential divider 7 and the voltage proportional to the secondary current developed across series resistance 17, or (b) the difference between the control voltage of potential divider 6 and the voltage proportional to the secondary voltage developed across a tapped portion of shunt resistance 18. The arrangement enables the metadyne, which may be of the generator or transformer type, to deliver either a current or a voltage which is maintained at a constant value controllable by the setting of potential dividers 6, 7. The control potential may be made the same in both positions by combining 6 and 7, or may be split up into several components, each responsive to a different controlling variable. The amplifier 5a may be composed of balanced thermionic valves, Fig. 2 (not shown). The switch 11, 12 may be replaced by a fader type resistance to give a smooth change-over. By putting a resistance-capacity or resistanceinductance network between the current- and voltage-sensitive elements and the variator winding, a time-lag is introduced which secures a more rapid response to a change in the controlling voltages. In a further modification, Fig. 3 (not shown), the current- and voltagesensitive components may be supplemented by small components sensitive to voltage and current respectively, by introducing a further tapping point on resistance 18 and a tapped shunt across resistance 17. The supplementary components may be additive or subtractive and the effect is to make the current and voltage to some extent interdependent, in departure from absolute constancy. The same effect may be obtained when the compensating winding over- (or only partly) compensates the armature reaction of the secondary current. The single variator winding may be replaced by a number of separate windings, each having a different excitation component. When the output of the metadyne is applied to a constant-excitation motor, acceleration with constant current and torque is obtained under condition (a) and running at constant speed under condition (b).

Title: Improvement in erection controlling device for gyroscopes
IPC: G01C19/44
Filed: 1942-09-25
Abstract: 602,235. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. Sept. 25, 1942, No. 13534. Convention date, Aug. 7, 1941. [Class 97 (iii)] [Also in Group XXXVII] In a gyroscope having three degrees of freedom wherein erecting torques are controlled by gravitationally responsive means, a second gravitationally responsive means balanced in a normally inoperative position renders the erecting torques temporarily inoperative during turns and other horizontal acceleration movements. In Fig. 3 is shown the interior of the erector case of a gyro-vertical employing the usual external erecting pendulums 25 controlling air ports 23. Inside the case and co-operating with each air port 23 is a pendulum 33 normally balanced in inoperative position by a spring 36. If a turn or other horizontal acceleration occurs, the appropriate internal pendulum 33 closes its air port and renders ineffective the corresponding external pendulum, thus preventing an erroneous erecting movement. In a modification, Fig. 11 (not shown), a weight suspended by a flexible element wound round a supporting shaft is balanced by a hair spring to control internal vanes cutting off the air jets during turns. In a further modification, Fig. 6, the invention is applied to a gyro-vertical, erected electromagnetically under the control of pendulums 52, 53 co-operating with reversing contacts 55<1>, 56 and 57, 58 which control threephase current supplied to a five-pole stator 48. The stator acts upon an electric conductor 45 attached to the rotor casing. During turns, the erecting device is rendered inoperative by opening the circuit of the erecting means at a contact 62, Fig. 7. This is effected by the centrifugal pull on a damped piston 63 supported by springs 61, 65 within a cylinder 70. The cylinder is pivoted on an axis 71 parallel to the axis of the corresponding pendulum 52 or 53. Specification 533,730 is referred to.
