Title: Improvements relating to automatic pilots for aircraft
IPC: G05D1/08
Filed: 1944-11-10
Abstract: 602,320. Automatic control of aircraft. SPERRY GYROSCOPE CO., Inc. Nov. 10, 1944, No. 22179. Convention date, Nov. 10, 1943. [Class 4] [Also in Group XXXV] In a system controlling an aircraft, horizontal thrust and vertical lift of which is dependent on the pitch of a sustaining propeller, cyclical variation of the pitch determining the direction of horizontal thrust, a compensating propeller counteracting reaction torque applied by the sustaining propeller about its axis of rotation is automatically controlled in accordance with deviation of the fuselage from a desired heading to correct such deviation. In Fig. 1 a sustaining propeller 22 of a helicopter is driven, throughshaft 23 and gear-box 29, from an I.C. engine 31 which also drives, through gear-box 29, a torque compensating propeller 98 to prevent rotation of the aircraft about the axis of the sustaining propeller. An aneroid bellows 11, sensitive to altitude changes, controls, through an electrical transmission system, a reversible electric motor 45 adjusting, by means-of a nut 49, the vertical position of a rod 53 to alter, through linkage 57, 58, the pitch and hence the lift of the sustaining propeller to maintain the aircraft at an altitude selected by the setting of a knob 14. Sensitivity of control is adjustable 'by electrical means. Limit stops imposing predetermined maximum and minimum limits to the angle of pitch of the sustaining propeller are referred to. A directional gyro 12 having an electrical pick-off 112 controls a reversible electric motor 116 coupled through a worm 107 to the base 106 of the gyro to maintain it in alignment with the gyro in conventional manner. Motor 116 controls, in turn, through an electrical transmission system a reversible electric motor 132 adjusting, through a nut 135 and linkage 141, the pitch of torque compensating propeller 98 to maintain a constant heading of the aircraft, selected by the setting of a knob 15. The angle of pitch of propeller 98 is subject to maximum and minimum limits. A gyro vertical 13 has electrical pick-offs 155, 156 associated with perpendicular horizontal axes controlling, through electrical transmission systems, reversible electric motors 168, 185, respectively, adjusting through nuts 171, 187, the vertical position of rods 174, 191 to set the position of the guide of a wobble plate 175 about perpendicular axes so that the pitch of the sustaining propeller is varied cyclically during each revolution. This results in the axis of the sustaining propeller being maintained in an attitude determined by the setting of knobs 17 and 18. Horizontal motion of the aircraft is controlled primarily by this attitude and the direction of motion is dependent upon the direction of the horizontal thrust component of the sustaining propeller as well as upon the heading of the aircraft. There are references to equivalent hydraulic or mechanical systems.

Filed: 1946-07-29
Abstract: 615,498. Sewing-machines. BATA, NARODNI PODNIK. July 29, 1946, No. 22493. Convention date, Jan. 30, 1943. [Class 112] Presser-bars.-In a boot-sole sewing-machine with a spring-loaded presser-foot subjected to additional pressure at times during the sewing cycle by a lever and rod connection from a cam or other driving means, in which an automatic adjustment for different thicknesses of work is provided by means of a threaded rod and nut, the rod and nut are incorporated directly in the connection to avoid the necessity for a second cam or other means to control them. In the arrangement shown, the presser-foot 1 is carried by a lever 3 which is pivoted on a feedbracket 5 and connected by a ball-jointed link 15 to a lever 18 biased by a spring 20 ; the presser-lifting treadle 26 actuates mechanism engaging the lever 18. The pressure-increasing and automatic adjusting device comprises a rod 30, connected to the lever 18 and sliding in bushes in a bracket 33, and a camactuated arm 47 linked to a collar 39 which slides on an extension of the right-hand bearing bush of the rod 30; a nut 34, having a conical end to fit in a corresponding recess in the collar 39, is mounted on a portion of the rod 30 having a quick-pitch thread and is pressed towards the collar by a spring 36, a ball thrust-bearing being interposed between the spring and the nut. During the periods when the cam is ineffective, the nut is free to be moved against the end of the right-hand bearing bush, rotating freely on the rod, but when the cam acts to apply the additional pressure the collar locks the nut against rotation so that the rod is carried along with the collar. The effective stroke of the rod may be varied by adjusting the bush longitudinally in the bracket 33 so that the collar has more or less lost motion before picking up the nut.
