Title: Voltage regulator systems
IPC: H02P9/38
Filed: 1964-07-09
Abstract: 1,055,496. Automatic voltage control. GENERAL MOTORS CORPORATION. July 9, 1964 [Sept. 20, 1963], No.28303/64. Heading G3R. The output voltage of a generator is maintained constant by varying the field current in dependence upon output voltage variations as detected by an oscillator which produces signals to control the switching of controlled rectifiers in the field circuit. As shown, the field winding 18 of an alternator 10 is energized by way of controlled rectifiers 44, 46, 48 from the output of the alternator which supplies a load 34 over a rectifier 30. An oscillator circuit comprising a transformer 80, a uni-junction transistor 96, a resistor 106 and a capacitor 108 is arranged to produce firing pulses when the output voltage is below a predetermined value these pulses being applied over capacitors 74, 76, 78 to the gates of the controlled rectifiers which are thereby turned on to allow current to flow in the field circuit. When the output voltage is too high, the oscillator circuit produces no output, and the controlled rectifiers are not rendered conductive; the field current is thus automatically controlled to maintain the output voltage at a desired value. The operation of the oscillator circuit is regulated by a voltage sensitive bridge comprising resistors 109, 114, 116, 118 and 120, a Zener diode 112 and a temperature compensating thermistor 126. A modification including an additional amplification stage is described with reference to Fig. 2 (not shown). The alternator may be provided with a bucking field winding associated with a second oscillator circuit which operates alternately with the oscillator circuit of the main field winding.

Title: Improvements in steering mechanism for flying machines
Inventor: ROHRBACH ADOLF
IPC: B64C13/42
Filed: 1924-11-27
Abstract: 226,516. Rohrbach, A. Dec. 18, 1923, [Convention date]. Balancing.- To prevent stalling in flying macliines, an auxiliary surface accommodating itself to the direction of the airstream adjusts the tail plane or other surface, as the angle of incidence of the wings increases, whatever position is given to the elevator. The elevator 1 is shown mounted on the tail plane 2 which is independently pivoted at 5. An auxiliary surface 3, freely exposed to the airstream, is mounted on an arm 7 pivoted at 6, the other end of the arm having a cam slot 8 engaging a pin 9 on, a rod 10 passing through guides 22. The lower end of the rod 10 is connected to a block 12 which slides on a guide 13 on the tail plane, the block being movable on the guide through a connection 16 to the elevator. At small angles of incidence no adjustment of the tail plane takes place, the lower end of the slot 8 being concentric with the pivot 6, but at larger angles of incidence of the main planes the angle of incidence of the tail plane is increased, and since upward movement of the elevator brings the block 12 nearer to the pivot 5 the automatic adjustment of the tail plane becomes more rapid as the elevator is raised, until ultimately further movement of the the elevator is completely counteracted. The moving parts are balanced to eliminate inertia effects.
