Abstract: A low frequency sonar projector (100) for use with a projector array having at least one ceramic stack (102) comprised of lead magnesium niobate-lead titanate (PMN-PT) having a Curie temperature Tm approximately equal to the operating temperature of the projector. A mechanism (104, 106) is provided for applying heat to and for controlling the temperature of the ceramic stack (102) to within a fixed operating range. A driving circuit (108) is included for providing a first electrical signal to polarize the ceramic stack (102) and for providing a second electrical signal to generate a mechanical output signal in the ceramic stack (102). Finally, a mechanism (110) is included for transmitting the mechanical output signal from the ceramic stack (102) to a fluid medium. In a preferred embodiment, a PMN-PT ceramic stack (102) is in intimate enclosed contact with an elliptical-shaped outer projector shell (110). The Curie temperature Tm of the PMN-PT is selected to maximize the electrostrictive effects of the ceramic stack (102) for improving projector performance. The stack (102) is surrounded by a heating coil (106) which is controlled by a temperature/heater control mechanism (104) to achieve and maintain the stack operating temperature within a fixed range. The ceramic stack (102) is polarized by a d.c. biasing circuit signal and mechanical vibrations are generated within the stack (102) by an a.c. driving circuit signal. The mechanical vibrations of the ceramic stack (102) cause excursions in the outer projector shell which, in turn, produce acoustic signals in a body of water. First and second alternative embodiments (200, 300) are disclosed with each embodiment housing at least one PMN-PT ceramic stack.

Abstract: For elongating and relaxing a bolt, a stud and the like (1) having an axis and arranged in an object (2), the stud (1) is connected with a first part (4) which is moveable only in an axial direction so as to pull the stud (1) in the axial direction to elongate the stud (1) and thereby to tension it in the object (2) or to relax the stud (1). The first part (4) is moved only in the axial direction by connecting the first part (4) with a second part (3) which is rotatable about the axis. A friction element (5) cooperates with at least one of the parts (3, 4) so as to change friction between the parts (3, 4) so that one of the parts (3, 4) has a higher friction than another of the parts (3, 4). The friction element (5) abuts against an outer surface of the object (2) without being connected to the object (2). Engaging means (13, 8) are provided on the parts (3, 4) for applying forces thereto. <IMAGE>

Abstract: A drive system comprising an integrated gearhead motor system that produces relatively high torque output with minimal backlash. The present invention uses two axially mounted electric or air motors and gearhead assemblies integrated into a single unit. The two motor and gearhead assemblies are connected to concentric output drive shafts, and each output shaft mates to a respective gear of a split gear assembly. The split gear assembly is coupled to a drive shaft of a device that is to be driven by the system. A tachometer is coupled between the first motor and a position sensor is coupled to the drive shaft of the device that is to be driven. The tachometer and position sensor are coupled to a controller that is used to control the respective torques provided by the two motors in response to rate and position signals provided thereby. By controlling the relative amount of torque provided by the two motors, the split gear assembly removes the backlash from the gearheads and gear interfaces to the drive shaft of the device that is to be driven. The present invention incorporates the two motors and two gearhead assemblies into a single assembly, reducing weight and space requirements. The design of the present invention also permits retrofitting of the drive system into existing single motor drive systems. <IMAGE>
