Abstract: 475,532. Adjusting wireless apparatus. STANDARD TELEPHONES & CABLES, Ltd., KNIGHT, S. G., and STAPLES, E. I. May 22, 1936, No. 14551. [Class 37] A tuning - control device, particularly for wireless apparatus for adjusting a condenser or other member to any one of a number of selected angular positions, comprises a plurality of normally fixed but angularly - adjustable coaxial rings having notches or projections on their inner peripheries and a rotatable control member carrying a pawl or plunger adapted to engage with any one of the notches or projections on the rings. The rings D correspond in number to the number of tuning positions to be selected and each is provided with a notch P and a projection Q. The rings are separated by non-rotatable washers and are stacked coaxially in a casing, clamped against a rear plate C by screws K or by a cam device. The rings are separately adjusted to the desired positions by the projections Q, so that when the control knob G is rotated to any one of these positions, a plunger H engages in a notch P on one of the rings. The plunger H is pressed outwards by a spring but can be moved inwards to disengage it from a notch by manually pressing in a spring-pressed rod which projects from the control knob G. This rod carries a cam surface which during the inward movement moves a rod coaxial with the control knob inwardly, so that a second cam surface on this coaxial rod engaging a pin on the plunger H moves the latter out of engagement with the notch. The tuning control dial is provided with a scale S cooperating with a pointer on the knob G and a shallow groove in the cover may accommodate metal pieces T. Alternatively, calibration marks may be engraved upon the cover or in a disc secured in the groove. A second knob M on a spring loaded pin provides, when depressed, a slow motion drive for the control shaft, which may be frictional or through gears Y, Z.

Title: Improvements relating to apparatus for the indication or control of the stability of synchronous dynamo-electric machines
Inventor: LINSELL RUSSELL FREDERICK
IPC: G01R31/34
Filed: 1949-05-31
Abstract: 664,703. Testing dynamo-electric machines. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 31, 1950 [May 31, 1949], No. 14633/49. Class 37. [Also in Group XXXV] Apparatus for indicating or controlling the proximity to instability of a synchronous machine comprises a miniature device having on a reduced scale the same electrical and mechanical characteristics as the machine to be tested and with means for applying a torque to the rotor proportional to the load on the synchronous machine. The two-pole miniature device 1, Fig. 1, has a rotor 2 with a single-phase winding and a stator 3 with a three-phase winding. The rotor 2 is mounted on a shaft 4 supported by bearings 5 and carrying a pulley wheel 6 by which displacement torque may be applied to the rotor by means of a solenoid 7 acting on a plunger 8 at the end of a cord 9. The pulley may also serve as a flywheel to give the required inertia to the device. The shaft also carries a pointer 10 moving over a scale 11. The alternator 12, Fig. 2, to be tested has an exciting winding 14 and windings 13 providing a three-phase output. The stator windings 3 of the device 1 are supplied through a voltage transformer 15 from the output leads 16 of the alternator 12, whilst the rotor winding 2 is fed from one phase of the output of the transformer 15 through a voltage stabilizing unit 17 and the main winding 18 of a transductor 19 whose control winding 20 is energized in accordance with the excitation of the alternator 12. The solenoid 7, which produces the displacement torque, is energized in accordance with the load on the generator by means of calibrated connections taken from a kilowatt meter 22. A device 23 may be provided for independent] increasing the solenoid current to simulate the effect of additional load on the alternator 12. At the position of balance between the resisting torque set up in the rotor 2 by interaction of the rotor and stator fields and the displacement torque applied to the rotor, the angular displacement of the rotor relative to the stator is proportional to the displacement of the rotor pole axis of the synchronous machine from its no-load position. The pointer 10 indicates directly in degrees the angle in electrical degrees between the rotor pole axis of the synchronous machine and its no-load position. If the load torque on the alternator exceeds the synchronizing torque and so renders the alternator unstable, the miniature device 1 also becomes unstable since its displacement torque will then exceed its resisting torque and this is apparent from the movement of the pointer 10. The rotor shaft may close contacts which actuate a signal or a regulating device to increase the excitation or decrease the load of the synchronous machine.
