Filed: 1920-01-20
Abstract: 140,376. Carroll, J. D. March 10, 1919, [Convention date]. Fixed-abutment type; packing drums, vanes, etc.; valve-gear; back pressure, reducing.-In a rotary engine of the sliding-rocking vane type, the vanes 59 rotate round a fixed eccentric 44, and slide through rocking members 66 in the drum 47. The drum is concentric and fast with the driving-shaft 1 and carries radial flanges 48 which overlap and form steam-tight joints with the ends of the cylinders 5, 6, forming the rotating side walls of these cylinders. The eccentricity of the two end cylinders 5 is diametrically opposite to that of the intermediate cylinder 6. An exhaust conduit 16, leading to the exhaust chamber 18 surrounds each cylinder. Steam is admitted through the rock valve 28 and the port 25 into the working chambers, and through the valves 92 into the valve cages 39, thus keeping the valves 36 closed. The valves 92<1> are closed, so that after each vane passes the exhaust port 43, any compression of trapped steam due to contraction in volume of working chamber is relieved through the poppet valves 36<1>. When the engine is reversed, the opposite cycle of operations takes place, the valve 92<1> being open. Spring packing-devices are fitted to the vanes, to the cylinder walls, and to the rockers 66.

Abstract: 1,032,084. Electromagnets. SPERRY RAND CORPORATION. Jan. 19, 1965 [Jan. 24, 1964], No. 2319/65. Heading H1P. [Also in Divisions G1 and H2] A combined pick-off and torquing device has a permanent magnet rotor 26 with polepieces 27, 28 capable of limited movement within stator 10 which has poles 11-14 each carrying two windings. One winding comprising coils 31-34 is connected to an A.C. supply and the other comprising coils 41-44 has induced in it a signal corresponding to rotor position. If the rotor moves away from the neutral position shown, the reluctance of the magnetic circuit changes by the polepieces overlapping a different amount of stator pole and a signal is induced in pick-off winding coils 41-44 which are serially connected and wound so that induced voltages in oppositely disposed stator poles add. A torquing action is provided by connecting either one of the stator windings to a D.C. source so that the resultant magnetic field produces a torque on the rotor. The device may be used as a self-restoring system by connecting the output of amplifier 46 through a phasesensitive demodulator 60 to the pick-off winding leads 56, 57, or an external servo loop may be used. To prevent cross-coupling the A.C. signals are suppressed by inductor 61 in the D.C. supply and the D.C. is prevented from reaching the amplifier (or A.C. supply) by capacitor 62. The device is used in conjunction with a displacement type gyroscope.
