Abstract: 278,018. Akt.-Ges. Brown, Boveri, et Cie. Sept. 27, 1926, [Convention date]. Void [Published under Scct. 91 of the Acts]. Addition to 186,036. Cut-out arrangements.-In the automaticallyreclosing circuit breaker system of the parent Specification in which the reclosure is held up after a given number of times by an electromagnetic relay with a mechanical line-lag, this relay is replaced by a thermal relay which has an inherent time-lag. As shown, when the circuitbreaker b trips it closes back contacts k which complete the energizing of the mechanical short time-limit relay f from the auxiliary transformer h and at the same time supply current from the same source to the thermal element p of the thermal long time limit relay. The closure of the relay f completes the circuit from the sourceh of the reclosing magnet m which recloses thecircuit-breaker after the short interval imposed by the relay f. This reclosing action continues. Owing to the thermal inertia of the heated element, after being heated up cumulatively a given number of times corresponding to the allowed number of reclosures, the thermal relay p opens and is retained in the open position by the catches o. The thermal relay remains open until reclosed by hand. The time-setting of the thermal relay may be adjusted by means of the resistance r.

Abstract: 1,035,065. Stabilizing ships. MUIRHEAD & CO. Ltd. April 1, 1965 [June 19, 1964], No. 25576/64. Heading B7M. Control apparatus for a ship stabilizer includes a gyroscope 1 (Fig. 1, not shown), which is sensitive to the angular velocity of the ship when rolling and mechanically coupled to opposite ends of a lever 25 whereby a rod or arm 27 connected to the stabilizer produces a mechanical signal constituted by a combination of a first mechanical signal proportional to said velocity and a second mechanical signal derived therefrom so as to be proportional to the angular acceleration of the ship, the signal given by the arm 27 having a leading phase-relationship with respect to the second mechanical signal (Fig. 2, not shown). The gyroscope has its axis of rotation in a horizontal plane and orientated athwart the ship, precession of the gyroscope about a vertical axis 2 within a fixed structure 3 being restricted to an angle of one degree by tension springs 4, 4<SP>1</SP>, 7, 7<SP>1</SP>. A free or floating lever 8 is pivotally connected at an intermediate point 22 to the gyroscope and one end of the lever 25 by a linkage system 9, 20, 23, 24. One end of the lever 8 is connected to an eddycurrent disc-brake 14, 15 by a link 16, a pivoted arm 10, and gearing 12, 13, whereas the other end is pivotally connected to a lever 17 which is biased by tension springs 19, 19<SP>1</SP> and coupled to the other end of the lever 25 by a link 26. The brake applies a load to the associated end of the lever 8 in proportion to the speed of the link 9 when the ship is rolling, whereby the displacement of the link 26 is proportional to the angular acceleration whilst the displacement of the link 24 is proportional to the angular velocity. The arm 27 is pivotally attached to the lever 25 at one of a plurality of points 28 according to the desired phase-relationship between the signal produced by the link 26 and that produced by the arm.
