Abstract: 553,875. Rectified D.C. supply for, telegraph systems. CREED & CO., Ltd., and MASON, F. P. Nov. 7, 1941, No. 14360. [Class 38 (ii)] [Also in Group XL] To provide telegraph signalling current of adequate voltage from the very low voltage battery supplying the fractional horse power motor which .drives the telegraph apparatus, the battery is connected with a transformer the stepped-up secondary voltage of which is rectified in the usual way and the automatic speed regulator normally associated with the motor is used to afford the necessary make-and-break of the primary circuit. The centrifugally-operated governor, under the influence of vibration and gravity, produces a cyclic interruption once per revolution which, at the highest speeds used, gives about 50 interruptions per second. In Fig. 1, the automatic governor 3 with contacts normally closed by a spring is connected in series with the motor across which the primary 8 is connected. A rectifier 4 across the motor and poled so that battery current will not pass disperses the voltage transient set up in the motor, on separation of the governor contacts and, in conjunction with the condenser 13, prevents sparking. The primary may be connected across the governor contacts or half of it so connected and the other half across the motor.

Abstract: 778,110. Fluid pressure brakes. CANADAIR, Ltd. May 19, 1955, No. 14460/55. Class 103 (1). In fluid pressure control systems for aircraft wheel brakes having inertia operated antiskid devices of the type manufactured under the Registered Trade Mark " Maxaret " and wherein control is by boost cylinder brake valve devices 16 whereby the brakes may be applied by pressure produced manually or from a pressure source supplying the feed line 13, it is arranged that so long as the main feed pressure (of about 3,000 p.s.i.) is available, a piston 73 is operated against a spring 81 to press a locking pin against a reduced diameter portion of the piston rod 78 thus reducing its possible travel to the distance " Y." This prevents the full capacity of the space 41 behind the piston 42 from being used except when there is a failure of feed pressure so that almost the full manual displacement may always be used, and undesirable exhaustion of fluid from the space by operation of the antiskid unit is avoided. The fluid system includes a check valve 26, Fig. 1, which prevents return of fluid through the line 24 to the reservoir 10, when the supply pressure fails, " locked on " conditions being prevented by check valves 29 which relieve the pressure from the brakes back to the boost cylinders 16.
