Abstract: 1290665 Control of A.C. motors DEFENCE SECRETARY OF STATE FOR 23 Jan 1970 [25 Oct 1968 1 Aug 1969] 50763/68 and 38617/69 Heading H2J A brushless cascaded servo motor has stator coils 1a, 1b, linked with rotor winding 2 which supplies a primary winding 3 carried by a separate rotor core. The winding 3 is linked with a stator winding 4, there being no direct flux linkage between the stator windings 1a, 1b and 4. Fixed or variable resistors 5 complete the circuits of winding 4 and are designed to prevent operation of the motor as a singlephase machine. A Scott transformer has a mains-connected three phase primary winding 7c and a secondary winding 7a permanently supplying the coil 1a. A further secondary winding 7b supplies the coil 1b through a reversing switch 8 which may take the form of thyristors or triacs responsive to error signals which are corrected by movement of the motor. A powerful locking torque is provided at standstill by operating switch 12 to connect one phase of the winding 4 to the A.C. supply in parallel with coil la. In another arrangement, the Scott transformer is dispensed with and the mains-connected stator windings of the motor are suitably modified. One phase is in two equal sections wound in opposite senses and with their junction connected to a centre tap of the other phase whose ends are permanently connected to two supply-lines. The free end of either section is connected to the third supply line through a reversing switch, Fig. 2 (not shown). In a further embodiment, the mains-connected motor winding is of the three-phase type. A bridge network is formed by the windings of two single-phase transformers, with two supply leads connected across one diagonal of the bridge and to two motor terminals. The third supply-lead is connected to one end of the other diagonal of the bridge, while the third motor terminal is connected to either end of the other diagonal through a reversing switch, Fig. 3 (not shown). The cascaded windings may be displaced circumferentially around the motor. Alternatively, the motor may be of the linear type.

Abstract: 1296074 Photographic exposure control CANON KK 29 Jan 1970 [29 Jan 1969] 4366/70 Heading G2A A photographic camera having a TTL exposure control system which includes a photo-sensitive element (not shown) is provided with interchangeable lenses each of which has a diaphragm pre-selecting ring 4 with a graduated scale 5 of equal spacing and carrying a linked movement pin 7 for engagement with a cam plate 9 of the camera. Each lens 1 also has a correction projection 19 the length of which is representative of the maximum aperture of its associated lens. Each pin 7 starts its stroke in the same fixed position Fig. 3 (not shown) regardless of the maximum aperture value of the lens. In use, a lens is attached to the camera and the projection 19 displaces to a greater or lesser extent a sliding piece 18 carrying the fulcrum of a reference lever 13 which in turn carries a needle 14. Thus the initial position of the needle 14 is determined in dependence on the maximum aperture of the lens, thereby correcting for e.g. Vignetting by the lens mount. When the lens is directed, with fully open aperture, at an object to be photographed, an indicator 3 of exposure meter 2 swings depending on the light available. The ring 4 is then rotated thereby depressing the cam plate 9. The lever 13 follows the plate 9 thus bringing the needle 14 into alignment with the indicator 3 thereby selecting the aperture. During picture taking, the diaphragm is brought to this selected value by a pin (8) actuated by appropriate camera mechanism. In another embodiment Fig. 7 (not shown), a single lens reflex camera using an electronic shutter and having a photo-conductive light  element (<SP>p</SP>) has the position of a variable resistor or variable capacitor altered by the projection (119), thus effecting an initial correction for the maximum lens aperture in the means for controlling the exposure.
