Abstract: An actuating assembly, including a rotatable core and an electric drive for driving the rotatablecore are disclosed. The rotatable core is arranged for engagement with a cable disposed within a pair of conduit sections and the cable can connect with a pair of actuatable devices. The rotatable core is arranged to be operable to pull the cable on each side of the core upon rotation thereof in a first direction, and to extend the cable on each side of the core upon rotation thereof in a second direction. The assembly further includes a pair of reaction abutments disposed on opposite sides of the rotatable core and to which a respective end of each conduit section can be connected. The assembly is arranged to be fixedly mounted and the reaction abutments are mounted for movement relative to the rotatable core for equalization of cable load transmitted through the conduit sections.

Abstract: A drum brake assembly including a rotatable drum having a radially inner braking surface and a brake shoe of single piece construction and of generally circular form mounted within the drum against a backing plate. The brake shoe has a radially outer face and a friction lining mounted thereon in facing relationship to the radially inner braking surface. Actuator having actuated brake on and released brake off conditions and being operable in the actuated condition to diametrically expand the brake shoe is provided. Positioners are also provided for positioning the brake shoe within the drum when the actuator is in the brake off condition to provide for complete clearance between the outer face of the friction lining and the inner braking surface of the drum. A grinding jig for grinding friction lining is also provided. A brake assembly having a connector for connecting the brake shoe to the backing plate.
