Title: Improvements in electric switches
IPC: H01H71/50
Filed: 1922-11-14
Abstract: 190,454. Akt.-Ges. Brown, Boveri, et Cie. Dec. 14, 1921, [Convention date]. Automatic circuit-breakers; sparking, preventing.-In a rapid-movement circuit-breaker employing few and light moving parts and spring pressure between the fixed and movable contacts to maintain the contacts in engagement, the contact pressure is removed instantaneously at the commencement of the breaking movement so as to leave a minimum of opposition to the withdrawal of the contact-member. As shown diagrammatically in Fig. 1, the contact b on the end of the light contact-lever k pivoted at h has a flexible-strap connection e to one of the currentcarrying sparking horns d and engages with a contact a mounted on the other horn c. In the closed position shown, a cable k, by engagement with the spring-controlled releasing member i, locks the circuit-breaker closed, against the action of the spring f. A resilient bearing of the contact b against the contact a is secured by a small spring between the cable and the lever g. A constructional form is shown in Fig. 2, in which the semi-circular arc horns c, d are in series with the blow-out coil o which provides also the exciting circuit for the overload trip magnet p acting through the armature q on the tripping lever i. A resilient catch k is employed to provide the spring pressure between the contacts. The force of the control spring l may be adjusted by raising and lowering the link t by means of a graduated cam-member s. On overload, the catch is freed and its pressure, on the movable contact removed, leaving the spring f to produce a rapid break. The circuit-breaker may be tripped by hand rotation of the toothed cam m which acts through the link v to strain the spring l. In the re-setting movement the cam m acts on a lever n to control the positions of the catch and allow it to assume the locking position.

Title: Improvements in radio direction finder
IPC: G01S3/06
Filed: 1937-11-16
Abstract: 488,823. Directive wireless signalling. HELLER, J. I. Nov. 16, 1937, No. 31463. [Class 40 (v)] Directional indications, free from night effect, are obtained from two vertical aerials 15, 16, Fig. 2, spaced apart on the wings of an aeroplane, and connected to a central receiver through two transmission lines 22, 23, screened and balanced against horizontal pick-up. If one pair of leads is crossed-over, as shown, the current through a shunt coil 25 will be zero when the machine is headed directly towards the transmitter, but will indicate deviations to port or starboard. A series coil 29 in the leads, Fig. 6, will carry the sum of the two aerial currents (if the transmission lines are not crossed-over) and will therefore give a circular or non-directional response. By combining the currents from the two coils 25, 29, through secondaries 26, 30 to a common receiver 28, Fig. 7, provided with a 90‹ phasechanging condenser 31, the cardioid curve shown in Fig. 8 is obtained, and can be periodically " reversed " by means of a local oscillator, Fig. 10 (not shown), to give a visual indication of the bearing line. Fig. 9 shows a complete installation with switching means for securing one or more of these directional indications. The coil 25 is switched over to give either a sum or difference effect, whilst the coil 29 serves as a " sense " indicator. With the switch 34 in the position shown, a relay 39 short-circuits the coil 29, a relay 38 nullifies the crossing of the leads, and the coil 25 gives a circular or non-directional response. With the switch 34 in position 36, the relay 38 " crosses " the leads to produce a figure-ofeight response. In position 37 the switch 34 energizes relays 38 and 39 so that the coil 25 gives a " difference " response, and brings the coil 29 into circuit for sense direction. The aerials 15, 16 may be combined with a similar pair set at right-angles, Fig. 11 (not shown). A movable search-coil coupled to crossed coils in the two transmission lines can then be used to take the bearings of off-course transmitters without the necessity of " swinging " the machine.

Filed: 1946-10-25
Abstract: 617,729. Gas turbines. MORDELL, D. L., and HOLLIDAY, J. B. Oct. 25, 1946, No. 31795. [Class 110 (iii)] Two gas turbine sets 10, 11 drive an airscrew 16 through over-running clutches 14, 15 and reduction gearing 17. When one turbine set ceases to operate, the fuel supply to the other set is reduced during the period of load adjustment. To this end, pipes 37, 38 lead from the fuel supply pipes 33, 34 to a drain 39 and include valves 46, either of which is opened when the other turbine set fails. Each valve is opened by means of a solenoid 44, the circuit of which is closed by contacts in the clutch 14, 15 of the other turbine set, when the driven member of the clutch over-runs the driving member. A dashpot 47 provides for quick closing and a retarded opening of the valve. The circuit of each solenoid 44 includes also contacts 53 which are normally bridged by a, sliding contact 51 actuated by a solenoid 49 in parallel with the solenoid 44. The dashpot 55 retards the movement of -the contact 51 so that the circuit of the solenoid 44 is broken only after a time-interval sufficient for the adjustment of the load. The pitch of the airscrew blades is varied to adjust the load through a servomotor 21 controlled by a speedgovernor 18. Clutches as described in Specification 612,652 may be used in place of the clutches 14, 15. In such case, the temporary rise of pressure in the hydraulic system may be used to close contacts in the circuits of the solenoids 44.
