Title: Electrical control system
IPC: G05D1/06
Filed: 1956-02-21
Abstract: 804,385. Automatic steering control systems. BENDIX AVIATION CORPORATION. Feb. 21, 1956 [Feb. 25, 1955], No. 5380/56. Class 38 (4). In an electrical control system, opposed outputs of two signal generators responsive to a variable cancel over a first range of variation of the variable but do not cancel over a second range, the resultant output being added to the output of one of the signal generators to produce an increased control signal over the second range. To cause an aircraft to fly along a radio beam, signals from a localizer radio receiver control rudder 15, Fig. 1, and ailerons 16 through a computer 13 and an autopilot 14. In addition deviations from a heading corresponding to the direction of the beam are detected by a magnetic compass 11, signals from an inductive pick-off 22 of which are applied through an inductive device 25, transformer 32 and computer 13 to maintain the correct course as set by knob 27 adjusting device 25. The deviation signal from the magnetic compass is also applied through a potentiometer 30 to an amplifier 35 to run an induction motor 48 adjusting, for small course deviations, an inductive device 51 until the signal it produces exactly cancels the compass signal. Upon large course deviations, however, stops 60, 61 limit movement of device 51 and the difference between the compass signal and the signal from inductive device 51 is added to the compass signal applied to computer 13 to increase the course correction signal under these conditions. Rate feedback is provided by a generator 49 driven by motor 48. A slipping clutch 52F is provided between motor 48 and inductive device 51 and when a magnetic clutch 53 is de-energized inductive device 51 is centralized by a cam 56. Specification 675,751 is referred to.

Title: An electric power interrupting device employing a controller for regulating contact closing speeds
IPC: H01H3/60
Filed: 1954-03-01
Abstract: 753,152. Automatic circuit-breakers; liquid-blast circuit-breakers. ALLIS-CHALMERS MANUFACTURING CO. March 1, 1954 [March 10, 1953], No. 5977/54. Class 38(5) In an oil-blast circuit-breaker 10, a controller 12 retards the initial speed of the moving contacts in the closing direction to avoid high velocity impacts at the end of the closing stroke. The main contacts 22, 23 are connected through a rod 24 to an operating linkage 97. 95, 93, 88, 85 84, 82, the link 85 being connected to an accelerating spring 52 and the top of rod 24 abutting a shock-absorbing spring- 53 in the closed position. Link 82 is connected by a rod 80 to a lever 54 and toggle mechanism 58, 57, 56 of a tripping and closing mechanism 11. To trip the breaker, a plunger 76 is operated either by an electromagnet 75 or a lever 77 to release a lever 71 which together with spring-loaded prop 65, holds the toggle mechanism set. Release of lever 71 causes the toggle to collapse and lever 54 operates rod 80 to open the breaker under the action of springs 52, 53. The controller 12, which is connected to rod 80 by a rod 108, is ineffective in the opening direction. The breaker is closed by a fluid motor 13 the ram 63 of which acts on a pivot 61 of the toggle mechanism to reset the latter and at the same time actuate rod 80 to close the breaker. During this movement, the controller 12 is effective to retard the initial speed of contacts 22, 23 until strong opposition of the springs 52, 53 and other springs in the arc-control chambers is met with. The controller comprises a cylinder 106. Fig. 4, fitting in one end of a cylinder 105 and containing a piston 107. Downward movement of piston 107 against a spring 104 on closing of the breaker causes a loosely mounted plate 113 to abut a seating 118 so that damping oil is forced through an aperture 111 in the plate and into cylinder 105. Near the bottom of cylinder 106, openings 114 allow oil to escape freely round the piston so that latterly its movement is unretarded. In the reverse direction (opening of the breaker), plate 113 leaves its seating 118 and the movement of the piston is unretarded. Fig. 2 shows one of the arcextinguishing chambers 17 of the breaker. during the closing movement of the latter a rod 33 is urged upwards by the contact bridge 21 against a spring 34 and the spring-loaded piston 42 of an oil pump 44. At the same time an arcing contact 30 connected to rod 33 is swung into engagement with a fixed contact 31. In the opening direction, downward movement of rod 33 under the action of spring 34 and_piston 42 disengages the arcing contacts and oil from pump 44 is forced through a baffle stack 50 to extinguish the arc between contacts 30, 31. The arc drawn out between main contact 22 and contact 19 is extinguished by oil forced through a baffle stack 51 by the latter arc.
