Title: Variable diameter propeller unit
IPC: B64C11/00
Filed: 1941-12-12
Abstract: 577,946. Propellers. HOOVER, W. S. Dec. 12, 1941, No. 16070. [Class 114] A propeller mechanism has blades mounted for radial and for pitch adjustment, the adjustments being effected by separate fluid-pressure actuators. In one form, Fig. 1, the blades 8 are carried by retainers 9 radially movable in ferrules 7a formed with gears 7 engaging a master gear 6 operable for pitch setting by a hydraulic vane motor 55. The retainers 9 and ferrules 7a have spaced vertical slots 12 containing balls 11 to allow of the radial movements of the retainers. The retainers 9 form hydraulic cylinders movable over pistons 14 formed on arms 13 extending radially of the hub 4, opposite ends of the cylinders communicating through passages 29, 30 with a valve chamber containing a piston valve 21. Oil from a reservoir in the hub passes into the valve chamber through a check valve 24 and thence through check valves 25 into chambers 26 from which it is pumped by pumps 18 under higher pressure through valves 20 and passages 27 into a groove 28 around the valve 21. The pumps 18 are plungers which are actuated, as the hub rotates, by engagement with a stationary cam ring 40. This ring is provided with a V-slot 38a engaged by a pin 38, Figs. 1 and 3, carried by a ring 37 angularly adjustable in either direction about the propeller shaft 3 by means of a pair of solenoids 43, 44. Upon movement of the ring 37 in either direction, the cam ring 40 is moved into position to actuate the plungers 18. A further ring 39 is provided with an oblique slot 38b also engaged by the pin 38 and this ring serves for adjustment of the valve 21. For this purpose, a slot 36 in the valve is engaged by an arm 35 on a pin 34 formed with gear teeth engaging rack teeth on a rod 31 constantly pressed into engagement with the ring 39 by a spring. Thus, as the ring 37 is moved in one direction by one of the solenoids 43, 44, the ring 39 positively moves the rod 31 to move the valve 21 to the right and when the ring 37 is moved in the opposite direction, the spring operates to move the valve 21 through neutral position and to the left. The movements of the valve 21 cause flow of pressure oil from the groove 28 to one or the other side of the pistons 14. To ensure equal radial movement of all the blades, the retainers 9 are connected by links 51 to a co-ordinating ring 52 rotatably mounted on the hub. The vane motor 55 for varying the pitch may be controlled by a governor-actuated valve mechanism 2 as described in Specification 563,008. In a modification, the valve 21 controls the vane motor simultaneously with the control of the flow of fluid to the pistons 14, and the ring 52 is secured to the rotor of the vane motor so that the pitch adjustment and radial adjustment of the blades are co-ordinated. The solenoids 43, 44 may be under the control of the pilot, or may be automatically controlled by the governor valve mechanism through a servomotor in the manner described in Specification 560,629, [Group XXIX], so as to co-ordinate the pitch and radial adjustments.

Title: Improved thermionic valve coupling arrangement for obtaining uniform amplification and selectivity over a large frequency range in wireless reception
IPC: H03J3/06
Filed: 1933-06-07
Abstract: 405,517. Valve circuits for wireless reception. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. June 7, 1933, No. 16355. Convention date, Nov. 17, 1932. [Class 40 (v).] Uniform amplification and selectivity over a large range of frequencies is obtained by providing that, as the receiver is tuned to higher frequencies, the internal resistance of the valve increases and its mutual conductance decreases. The control of the valve constants may be effected by varying grid bias, as shown, or by varying the screengrid voltage or the cathode emission. The valve has preferably a variable amplification factor and the frequency characteristic of the audio frequency amplifier may be varied with the tuning to obtain correction for frequency discrimination due to the selectivity of the high frequency amplifier.
