    Abstract: A loading device for a machine tool in which a workpiece holder is arranged to be mounted on a machine tool, the workpiece holder having releasable gripping means associated therewith for retaining the workpiece. The gripping means is provided with a tapering surface arranged to provide, in conjunction with a cooperating tapering surface on the workpiece holder, a stickingtaper wedging action to grip the workpiece on axial movement of the workpiece into or over the gripping means. The gripping means is also arranged to permit the workpiece to be withdrawn therefrom solely by an axially directed extracting force applied to the workpiece, of which the following is a specification.

    Abstract: In an aircraft brake a brake thrust transmission member is arranged between a stack of friction members and a circular arrangement of spaced brake actuators to provide even circumferential distribution of the localised thrusts exerted by the actuators. The transmission member has at least one deformable section of frusto-conical shape, an annular ring engaged by the actuators, and another annular ring, which may have two or more co-planar surfaces, for engagement with a friction member.

    Abstract translation: 在飞机制动器中，制动推力传动构件布置在摩擦构件的堆叠和间隔开的制动致动器的圆形布置之间，以提供由致动器施加的局部推力的均匀圆周分布。 传动构件具有截头圆锥形状的至少一个变形部分，由致动器接合的环形环和可具有两个或更多个共面的表面的另一环形环，用于与摩擦构件接合。
