Abstract: 1524723 Automatic voltage control INTERNATIONAL BUSINESS MACHINES CORP 1 Oct 1975 [16 Dec 1974] 40078/75 Heading G3R [ Also in Division H1] A ferroresonant transformer for a regulated power supply comprises an I-shaped stack of laminations 16', a C-shaped stack 18', and an E-shaped stack 20' assembled as shown with airgaps 26', 32', a primary winding in two parts 22', 24' on the I-shaped stack, a secondary winding 27", 28" on the outer legs supplying a D.C. load through rectifiers 42, 44, a resonating winding 27', 28' on the outer legs connected with a capacitor 40, and a control winding 30 on the centre leg. The winding 27', 28' and capacitor 40 are resonant at the supply frequency leading to saturation of the outer legs each half cycle in conventional ferroresonant manner. The control winding 30' is fed with D.C., as shown derived from the output via a variable resistor 50, and provides a biasing D.C. flux in the core. Should the output current rise the control current lc increases, increasing the biasing flux and reducing the output from the windings 27", 28" and hence the output voltage. In a modification, Fig. 4, the D.C. control current 1c is derived from separate windings 87, 88 on the core which through rectifiers 82, 84, provide a direct voltage across a capacitor 89. A measure of the voltage across the load 90 is derived via resistive network 96, 98 and applied to one input of a comparator amplifier 100 whose other input is fed with a reference voltage derived from potentiometer 102. The output of the amplifier controls a transistor 105 feeding the control winding 30, such that automatic regulation of the output voltage on the load 90 is effected. A further modification, Fig. 5 (not shown) is similar to Fig. 2 but includes diodes in the circuit of the winding 27', 28' and capacitor 40.

[Also in Division G1] A gyro-stabilized optical sight system for use in a vehicle comprises an optical sighting system defining an optical first path 11 and means for correcting the path 11 in accordance with vehicle movements. The correcting means include a second, gyro-sensitive, optical system defining an optical path, detector means 28 responsive to changes of the second path with vehicle movements, optical means 15 in the two paths on a common support 19 and means controlled by the detector means to move the support to effect correction of the first path. As shown, the optical sighting system for the target 13 is formed by a telescope 13 and mirrors 14, 15. The second optical system is formed by a light source 32, lens 33, optical threads 34, aperture 31 in the centre of the detector 28, negative lens 36, mirrors 37, 25 and mirrors 15, 39. The detector 28, lens 36 and mirrors 37, 25 are all mounted on the inner gimbal 29 of a conventional two-axis gyroscope having a rotor 24 rotating about axis 23. The arrangement is such that normally the light is reflected back from mirror 39 to fall on the centre of the detector 28 but if the mirrors 15, 39 have moved with the vehicle with respect to the gyroscope optical system fixed in space and pointing at the target the light will fall off centre on the detector which causes the motors 21, 17 to rotate the mirror 15 in azimuth and elevation respectively until the original position with respect to the gyroscope is assumed and the optical sighting path is again pointing at the target. The gyroscope has a pair of precession coils 26, 27 for applying a torque to the gyro in accordance with a hand-operated control 30. In a modification the detector is mounted on the gimbals 19 of the mirror 15.

Abstract: 1,150,481. Drying webs. PROCTOR & SCHWARTZ Inc. 13 Sept., 1966 [14 Sept., 1965], No. 40869/66. Heading F4G. [Also in Division D1] Apparatus for drying textile webs with gaseous treatment media, comprises nozzle means 25, 26 on opposite sides of the web path, the nozzle means having elongate nozzle openings 29, 30 disposed at acute angles to the direction of web travel, the angles being oppositely directed on opposite sides of the path to provide crossing points for the streams of treatment media leaving the nozzle openings. The nozzle means are situated in a housing and connected at one end to a plenum chamber supplied with the treatment medium, a damper preferably being provided in each nozzle means to control the flow of medium. Each nozzle means preferably comprises a pressure box tapering towards the opposite side of the housing from the plenum chamber. The web to be treated, in the particular embodiment, passes through the housing in three superposed horizontal runs on conveyers preferably formed of rods or girts. Each nozzle opening may be provided with vertical partitions e.g. 32, to effect a perpendicular stream imping- ing on the web. At the crossing points the streams of treatment medium act on the same portion of web from opposite sides and tend to compress the web; at the points where the streams do not cross, the web tends to billow, the web is thus gently agitated during treatment, which is of advantage to developing texturing characteristics in so-called "textured" yarns. In an alternative embodiment, each nozzle means is provided with branch nozzle means at right angles to the main nozzle means. Each branch nozzle means is also provided with an elongate nozzle opening, and the arrangement is such that the branch nozzle openings of one set of nozzle means overlie the main nozzle openings of the other set of nozzle means. The crossing points of the treatment medium streams may be randomly disposed over the web by varying the angles at which the nozzle openings are set or by varying the spacing between adjacent nozzle means.
