Abstract: A loudspeaker includes an acoustic diaphragm, an oscillatory force source, a lever coupling the oscillatory force source to the acoustic diaphragm, and a pivot coupled to the lever such that the lever moves in an arcuate path about the pivot when the oscillatory force source applies a force to the lever. The pivot includes at least one torsion bushing. The at least one torsion bushing includes a first member, a second member coupled to the lever and movable relative to the first member, and an elastomeric member coupling the first member to the second member. Either the first member or the second member is coupled to and moves with the lever. An outer surface of the elastomeric member is coupled to the second member via mechanical compression.

Abstract: A wind turbine generator includes an outer housing, a drive shaft rotatably mounted within the outer housing, stator and rotor assemblies positioned within the outer housing and movable relative to each other, a heat exchanger, and a blower having a rotating plate for generating a fluid flow circuit within the generator for transporting heat from the stator and rotor assemblies to the heat exchanger. An eddy current brake having a rotating member is located within the outer housing and is positioned in the fluid flow circuit such that fluid moving in the flow circuit cools the first rotating member. The blower and the eddy current brake may be integrated, such as by having the rotating plate of the blower serve as the rotating member of the eddy current brake. A wind turbine having such a generator, as well as a method of operating a wind turbine generator is also disclosed.

Abstract: A parking brake apparatus includes a base plate, a brake lever supported by the base plate, a pair of left and right brake actuating units, and left and right brake cables connecting between the brake lever and the left and right brake actuating units, respectively. The base plate has an elongated hole extended from a corresponding position to a cable connecting portion of the brake lever toward the outer cable holding portion, left and right inner cables of the pair of left and right brake cables are connected to a common inner cable by an equalizer, and the common inner cable is extended inside the elongated hole from the cable connecting portion toward the outer cable holding portion.

Abstract: A central control braking system includes: a pedestal; at least one caster mounted at a bottom portion of the pedestal; a brake transmission shaft for controlling the caster; a plate girder movably connected to the pedestal; a pedal fixed to the plate girder; and a reversing rotary assembly connecting the plate girder and the brake transmission shaft, wherein the reversing rotary assembly enables the brake transmission shaft to rotate in reverse under the control of the pedal.

Abstract: A pedal (10) is formed from a single molding and includes first and second arms (12, 14), each provided with an over molded marker (16, 18). The pedal (10) has two fittings (20, 22) for coupling with a brake actuator rod (24) and a coupling member (26) respectively. A castor (40) includes a wheel (42) which can rotate about a bushing (44) and a coupling shaft (46). Within the shaft (46) there is provided a brake mechanism for locking the wheel (42). A base frame (80) for a bed includes longitudinal and transverse struts (52, 54) arranged in a rectangular form, with four castors (40) and four associated pedal assemblies (10). Two actuator rods (24) are provided, one for each pair of opposing pedal assemblies (10), while two connecting elements (26) are provided, one for each pair of side-by-side pedal assemblies (10). All the pedals and thus all the brake mechanisms are coupled to one another through the two actuator rods (24) and two coupling elements (26).

Abstract: A park brake linkage includes a pivotable park brake actuating handle, a park brake bell crank rotatably mounted on a cross shaft, an arm extending radially from the park brake bell crank, and a single connector between the handle and the firs arm to transmit pivoting movement of the handle to rotational movement of the park brake bell crank. A second arm may extend radially and laterally from the park brake bell crank, which may be used to turn a left brake bell crank and a right brake bell crank, each of which may be secured to a separate brake camshaft. Each camshaft has a cam lobe extending therefrom to apply a brake.

Abstract: A brake assembly is provided for use with a utility vehicle. The brake assembly includes a mechanism including a pair of compression springs configured to provide the ability of one brake to be further applied after one brake has been completely applied. A parking brake is also provided which includes a ratcheting feature.

Abstract: An improved brake control apparatus automatically engaging the park brakes of a vehicle when the vehicle ignition switch is turned to the off position and automatically disengaging the park brakes of a vehicle when the vehicle ignition switch is turned to the on position. The brake control apparatus is constructed to be utilized in cooperation with an automobile park brakes and with the park brakes of a trailer or the like, for example, the brake control apparatus being installable as an accessory item or as original equipment.
