Title: Rotary electrical machine
Inventor: HELPS FREDERICK GEORGE
IPC: H02K19/14
Filed: 1958-05-16
Abstract: 847,718. Electric motors. SPERRY GYROSCOPE CO. Ltd. Feb. 20, 1959 [May 16, 1958], No. 15824/58. Class 35. A motor designed to run at a sub-synchronous speed has a toothed rotor 5 and a series of poles 1, 2, 3 provided with teeth 8 of slightly different pitch to those on the rotor, so that as the poles are energized (or de-energized) in sequence the rotor moves through a fraction of a tooth-pitch at each pole, and moves through a complete tooth-pitch during a complete cycle of energization. The sequential energization of the poles is by means of a three-phase supply acting through half-wave rectifiers as shown so that the poles are each energized to a maximum in succession. As shown, the stator teeth have a spacing equivalent to a total of 42 evenly distributed stator teeth, gaps being actually left between the poles, while the rotor has 40 teeth. Rotor oscillations are damped by squirrel-cage bars 7. To ensure smooth action, the stator and rotor teeth are either of equal angular width or else relatively skewed. The outer, salient-pole member may rotate and the member 5 remain stationary.

IPC: G03B17/42
Filed: 1919-06-25
Abstract: 128,938. Bass, E. C. June 25, 1918, [Convention date] Kinematograph apparatus.-In a camera for roll-films, the film is intermittingly fed by claw teeth on a reciprocating frame which works in conjunction with a sliding plate shutter having two blades. The shutter is set for an exposure during a feed movement of the frame and on the return idle movement an exposure is made. The frame 33, Figs. 1 and 2, carrying claw-feed members 30 is reciprocated by cranks 41, 40 and springs 34. The film 24 is wound on the take-up roll 51 by a rack bar 52 actuated from the crank 40. The frame 33 also carries one of the shutter blades 61 which has an opening 63 normally registering with the exposure opening in the fixed plate over which the film travels. This exposure opening is closed by the second blade 62 of the shutter which has an adjacent opening 64. On turning the shaft 42 to feed the film, the frame 33 carries the blade 61 forward which in turn carries the other blade 62. At the end of the forward movement, a lever 71 is released from the retaining arm 65 on the blade 61 and engages behind a projection 70 on the blade 62, and the blades are now in the position shown in Fig. 5. As the slide 33 moves back under the action of the springs 34 the opening 63 in the blade 61 moves back into register with the opening 64 in the blade 62 to effect an exposure, and the projection 75 on the arm 65 engages the cam portions 74 of the arm 71 and disengages it from the blade 62, which now returns under the action of a spring 80. The speed of closure is controlled by tensioning the spring 80 on a roller turned by the knob 88 and held in position by a plate 85, Fig. 1, having a pin 86 engaging one of the) holes 87 in the mounting 21. To hold the frame 33 in set positions for an exposure, a turn knob 100, Fig. 9, is used for rotating the shaft 42 and has an arm 101 which is held by a spring plate 103.
