Filed: 1967-11-24
Abstract: 1,195,875. Automatic control. SPERRY RAND CORP. Nov.24, 1967 [Dec.1, 1966], No.53468/67. Heading G3R. In a closed loop control system for positioning a movable member, signals produced by misalignment between a position pick-off and the movable member are converted to digital form, stored, and re-converted to analogue form for subtraction from the pick-off signals to eliminate the effect of the misalignment. As shown, the pitch attitude of an aircraft 14 is automatically stabilized by signals from a gyro-vertical (not shown) applied through an amplifier 31 to an electro-hydraulic actuator 32 controlling elevator 16. Follow-up signals dependent on elevator position are derived by applying A. C. signals from a pick-off 13, detecting the position of stabilator 11 relative to the aircraft, and a pickoff 17, detecting the position of elevator 16 relative to the stabilator, through amplifiers 22, 24 to the input of amplifier 31. To eliminate error due to incorrect positioning of the pick-offs, e. g. error caused by signals from pick-off 17 when elevator 16 is in streamline position relative to stabilator 11, the pitch control is disengaged and the output of amplifier 24 applied through a gate 25 to an amplifier 36 the output of which is periodically sampled by a switching transistor 38 and applied to a trigger circuit 37 producing numbers of pulses corresponding to the magnitude of the error above a predetermined minimum value. The phase of the pulses is determined in a comparator 39 so that they are stored separately, according to the sense of error, in a counter 42 the output of which is converted by A. C. analogue form at 43. The output of converter 43 is applied to the input of amplifier 24 in opposition to the pick-off signals so as to eliminate the error, such elimination being independent of variations of supply voltage. When pitch control is engaged, the output of amplifier 24 is still correct by virtue of the error correction stored at 42, and this output, besides being applied as follow-up to amplifier 31, is also applied through a low gain circuit 26 and gate 29 so that, if it is sufficiently large, it operates, through amplifier 36 and trigger 37, a servo 41 to trim stabilator 11 automatically. Phase comparator 39 is rendered inoperative under these conditions, and a resistance-capacity delay network at 40, or elsewhere, may prevent trimming in response to signals of short duration.

Abstract: 1284685 Mechanical switches SQUARE D CO 16Novl970 [18Decl969] 54368/70 Heading HlN A switch assembly comprises at least two switches (54, Figs. 2 and 5, not shown) having self-restoring reciprocable push buttons 52 mounted for operation by respective pins 45 engaged by a cam member 36 which is selectively slidable along two mutually-perpendicular paths in a base member 43 upon movement of a "joy-stick" operating lever 24 pivoted at 29 in a body member 10 and guided in planes corresponding to said paths, the said movement being restricted by a guide plate 39. As described the switches are of a type having an intermediate OFF position and the cam member 36 is shaped (Fig. 3, not shown) to provide three camming surfaces for each pin 45. As shown in Fig. 1 the pins 45 are holding the switches in their OFF condition. When cam member 36 is moved respectively left or right a surface 69 or 70 allows the associated pin 45 to rise under action of its associated button 52, while movement perpendicular to the plane of the drawing causes a surface 65 to depress the righthand pin 45 or a corresponding surface (64, Fig. 3, not shown) to depress the lefthand pin 45. Thus either switch can be selectively moved "up" or "down" while the other switch remains OFF. A spring- loaded collar 38 on lever 24 coacts with guide plate 39 to retain the lever 24 in its operated positions, or, if the guide plate 39 is formed with suitably curved recesses (as in Figs. 6 and 8, not shown), the collar 38 is lifted against springs 40 and 41 when the lever 24 is operated and provides a retracting force. The guide plate may limit the movement of lever 24 to one plane (Figs. 6 and 9, not shown). If the switches 54 have buttons 52 exposed for access through the bottom of their respective housings further switches (57, Fig. 2, not shown) may be mounted in tandem for conjoint operation. In a modification (Fig. 10, not shown) a spring-loaded rod (89) coaxially within the lever 24 carries a crosspin (92) coupled to a sleeve (93) which normally engages the central portion of the cruciform opening 21 in body 10 and locks the operating lever 24 until the end of the rod (89), forming a push button (89a) in the tip of the lever 24, is depressed.

Abstract: 1327440 SCR control circuits AUTOELEKTRONIK AG 18 Nov 1970 [20 Nov 1969] 54849/70 Heading H3T [Also in Division F1] An SCR 6 is triggered on by the current surge into a capacitor C2 when another SCR 5 turns on, C2 being discharged by a circuit including for example R2, D2, R4, D6, and both the charging and discharging of C2 being controlled by a switch U. The switch U is driven by rotation of an internal combustion engine whose ignition is effected by the SCR 6, which discharges a capacitor C3 into a transformer 7 driving a spark-gap F. Assuming a capacitor Cl to be initially charged, the opening of contacts 3a, 3b removes the earth connection from D6 cathode and allows current from Bt to flow into C2 through R5, D3, R4, R8, R2 until gate G5 of SCR 5 is positive enough to turn on SCR 5. This enables C1 to discharge via a transformer winding 2c and the SCR 5 into C2. The sudden current thus produced in R7 produces the igniting signal for SCR 6. A pulse is also applied via winding 2c to a transistor T, which is thus turned on. When it subsequently blocks and turns off again, an induced voltage across the primary 1a of a transformer 1 recharges C1 through D1, and the secondary 1b recharges C3, ready for the next cycle. Before the next cycle however, contacts 3a. 3b close to discharge C2 through R2, D2, R4, D6 to earth; the time constants being made large enough to ensure that contact bounce of 3a, 3b does not erroneously re-energize SCR 5.

Abstract: 1,254,296. Transistor sawtooth generators. HONEY WELL Inc. 29 Nov., 1968 [10 Jan., 1968], No. 56855/68. Heading H3T. A sawtooth generator has a capacitor 20 charged from a constant current source 54, and a voltage sensitive switch comprising, for example, a Zener diode 82 and an S.C.R. 84, which produces a pulse when the sawtooth reaches a predetermined level, to operate a monostable 98, 108 which shorts out the capacitor 20 for a given time, such as by turning on a transistor 22. The constant current is adjustable by a switch 58, and the negative reference level of the sawtooth is adjusted by a potentiometer 42. The voltage on the capacitor 20 is transmitted by a Darlington pair 62, 64 to the Zener diode 82. When the S.C.R. conducts, upon the capacitor reaching the predetermined voltage, its cathode positive-going voltage is differentiated at 94 and triggers the monostable 98, 108 into its unstable state. The duration of this is adjustable at 122. During the unstable period transistor 22 conducts to discharge capacitor 20. It is said that valves and switches may be used instead of transistors.
