摘要： The combination, with a rotatable driving member and a cooperating rotatable driven member, of a bi-directional torque limiter which operates to limit the torque which can be transmitted from the driving to the driven member irrespective of the direction of rotation of the driving member, said torque limiter comprising a spring loaded connection between the driving and driven members which includes an element which normally partakes in the transmission of the drive but which, when the output torque reaches a predetermined limit, is arranged to move against spring action into engagement with a fixed element to relieve the driven member from the input torque.
摘要翻译：具有可旋转驱动构件和配合的可旋转从动构件的组合，双向扭矩限制器，其操作以限制可以从驱动构件传递到从动构件的扭矩，而与驱动构件的旋转方向无关，所述扭矩限制器包括在驱动和被驱动构件之间的弹簧加载连接，其包括通常分布在驱动器的变速器中的元件，但是当输出扭矩达到预定极限时，该元件布置成抵抗弹簧动作移动以与固定元件，以从驱动构件中减去输入扭矩。

摘要： A position control servo system comprising a hydraulic actuator controlled by a fluid control valve which is responsive to output signals applied to it from a pair of transducers, each of which is responsive to an input signal applied thereto to produce an actuator output which a function of the input signals, which are in normal operation substantially equal, and control means responsive to a difference between the transducer output signals up to a predetermined and allowable difference to adjust on or the other or both of the transducers and/or input signals thereto, thereby to maintain the tranducer output signals within the predetermined and allowable difference and to produce an indication when the difference is exceeded.

摘要： 957,573. Epicyclic change-speed gear control. H. M. HOBSON Ltd. April 25, 1963 [March 23, 1962], No. 11276/62. Heading F2D. [Also in Division F1] The torque reaction member of an epicyclic gear, between an aircraft jet engine and an alternator to be driven at constant speed, is controlled by an air turbine at engine speeds from zero to above idling speed and by a positive displacement pneumatic machine above these speeds. A ring gear 20 is driven from the engine and the alternator is driven from the planet carrier 21, torque reaction being supplied by an air turbine 26 coupled by gears 25 to the sun gear 23. The sun gear 23 is connected through a free-wheel 46 to a gear 27 meshing with a gear 28 drivingly connected to a Rootes blower 30 and a ring gear 31 connected by free-wheel 27 to the ring gear 20. At zero engine speed, the alternator is driven from the turbine 26 by air from an auxiliary supply through pipe 40, an output shaft governor 15 maintaining the alternator speed constant by control of a valve 38 and turbine guide vanes 39. When the engine starts, interconnected controls 35, 37, 38 permit running of the turbine from the final stage of the engine compressor until the engine speed rises to a point between idling and aircraft stand-off speed, at which point the blower 30 provides reaction by acting as a compressor and the turbine commences to act as a compressor. For engine starting the blower 30 is run as a motor from auxiliary air supply and, in the event of engine failure, the turbine is fed from an air supply from another engine through pipe 42 to drive the alternator. Specification 871,576 is referred to.
