Definitions

  • the invention aims to effect an accurate adjustment on the controlled side even if the adjustment on the control side happens to be inaccurate.
  • FIG. 1 is a partially diagrammatic view of one embodiment of the invention
  • Fig. 2 is a side view of part of the arrangement shown in Fig. l
  • Fig. 3 is an arrangement showing the differential gear box at right angles to the view shown in Fig. 1, together with a repeater drive means. Only the adjusting means is represented here, the means to be controlled, such as condensers and variometers, not being shown.
  • a driving means I is arranged to drive a drum 4 by the intermediary of a flexible shaft 2 of suitable length and by a worm gear 3.
  • This drum contains a differential gearing as shown in Fig. 3 and is connected with the means to be controlled.
  • the differential gearing comprising four beveled gears 11, b, c, d, and ring gear e serves to drive the disc I and a disc It.
  • a scale 5 is arranged to indicate the angle value 6 also indicated on the controlledside.
  • Disc 'I has radial slots in its circumference and is thereby adapted for cooperation with a stop lever 8 provided with an offset arm 8A and a detent arranged to enter these slots. If on the control side a device similar to the stopping means 1, 8 were employed then the operator would neverbe-sure whether or not lever 8 has engaged the disc 1 by entering the respective slot thereof.
  • lever 8 when the dent of the lever enters a slot of the rotating disc 1 comes against a lever 8 which is thereby separated from disc l0 releasing this disc for rotation with beveled gear 11.
  • Lever 8 may to such en-d be spring-actuated. As long as disc III is held from rotation, only disc I is driven by gear 0, since the faces of levers 8 and I3 are shaped so as not to absolutely block movement of disc I.
  • lever 8 will have engaged the disc I irrespective of 'whether or not on the transmitting or control side the stoppage or indicatiomas the case may be, is effected in accordance with the ame angle value as on the controlled side.
  • a rotating field system may be employed as shown in Fig. 3.
  • the generator S is driven by rotation of control shaft I, and the follow-up motor E is consequently rotated to drive worm gear 3 over the shaft 1.
  • a remote control system which comprises a control station and a controlled station, driving means at said control station, a ratchet disc, gearing means at said controlled station operated in response to operation of said driving means for driving said ratchet disc, indicating means operatively associated with said driving means for indicating the rotational position of said disc,
  • a remote control system according to claim 1 which further comprises high frequency tuning,
  • a remote control system according to claim 1 wherein said pawl holds said disc in a predetermined position before said indicating means indicates said position for a period equal to the period between the indication of said position and the release of said disc.
  • a remote control system which comprises a control station and a controlled station, driving' means interconnecting said stations, difierential gearing means at said controlled station operated by said driving means, two disc members alternately driven by said gearing means, one of said members having slots thereon and the other of said members having a projection thereon, a
  • first pair of pawls the first of said pawls being arranged to cooperate with said slotted member and having means to render the second of said pawls inoperative upon engagement with one of said slots and the second of said pawls being arranged tocooperate with said other member for engagement with said projection
  • a second pair of pawls the first of said second pair of pawls being arranged to cooperate with said slotted member and having means to render the second pawl of said second pair inoperative upon engagement with one of said slots and the second pawl of said second pair being arranged to cooperate with said other member for engagement with said projection, the first and second-pawls of each pair of pawls being simultaneously operative.
