摘要： A solid state power amplifier for driving a shaker. The amplifier is comprised of a circuit which generates a pulse-width modulated drive signal for driving an armature of a shaker. The circuit includes an oscillator (91) (92) (93), power supply (94-97) and (100-103), wave-shaping generator (98), error detection network (109), comparator modulator (116) (118) and drive amplifiers (121) (122). The oscillator generates a base waveform which is shaped by the wave-shaping generator. This signal is compared with error signals and the resulting signal is used to provide the pulse-width modulated driving signal to the shaker.

摘要： An externally excited resonant free piston Stirling engine thermal amplifier system which is over damped at all load levels and will not freely oscillate and wherein the displacer/piston system of the Stirling engine is externally driven by a separate drive motor (14). The system includes means for sensing at least one preselected operating parameter of the Stirling engine thermal amplifier (21, 29) and/or the load driven by the Stirling engine thermal amplifier (16) and deriving feedback signals indicative of such operating parameters. The system further includes feedback means responsive to the operating parameter sensed signals and operative to develop control signals for variably controlling the drive motor (14) to thereby precisely, variably and stably control the operation of the Stirling engine thermal amplifier system.

摘要： A hydraulic drive system operates from the periodic pressure wave produced by a Stirling engine along a first axis thereof and effects transfer of power from the Stirling engine by a power coupling flexible diaphragm (12) to a load apparatus, such as a compressor. The movable, or working member (15) of the load apparatus is reciprocatingly driven along an axis substantially at right angles to the first axis. A counterweight (30) may be freely slidable on the working member in the bore (14) of the load apparatus and is driven in the opposite direction to the working member by the incompressible fluid in a constant volume space (33) so as to damp out transverse vibrations. This arrangement of a Stirling engine and load apparatus assembly is much more compact and reduces transmission loss. The components of the load apparatus are also more readily accessible.

摘要： A linear reciprocating electromagnetic machine (10) has an outer stator member (12) having axially spaced apart pole pieces (22') and (24'), an open-slot coil cavity (18) housing a coil, and an inner stator member (14) spaced from the outer stator member (12) and providing means for completing a path for magnetic flux. The machine also includes a permanent magnet plunger (16) arranged for reciprocation with respect to the stator members and within the space between such stator members. The plunger (16) is provided with three permanent magnet segments (28), (30), and (32) arranged axially along the plunger (16) such that the interface zones between the magnet segments are substantially within the region defined by the stator pole pieces for all operating axial positions of the plunger (16). The two outer magnet segments are of equal axial length while the center magnet segment is axially longer than an outer magnet segment by an amount equal to the axial length of the open slot of the coil cavity.

摘要： The present invention relates to a resonant piston compressor (10) in which a double-sided piston (18) reciprocates within a cylinder (24) and defines a valved compression space (26) on one side of the piston and a balance chamber on its other side. The invention further includes a movable head (110) adjustable between first and second positions to effect a large change in the total volume of the balance chamber between the two positions. In one position, of the movable head (110) an extended balance chamber volume is coupled to the balance chamber while in the other position of the movable head (110), the extended balance chamber volume is decoupled from the balance chamber.

摘要： An electro-mechanical shaker apparatus (10) utilizing a novel design. The shaker apparatus (10) includes an armature frame (30) which is directly coupled to an armature coil (20) to form an integrated unit. The shortened height of the unit effectively raises telescoping resonant frequencies above the spectrum of test frequencies. The armature frame (30) is comprised of a top plate (51), bottom plate (52), and an intermediate section (53) to form a laminated/honey-combed design. The top and bottom plates (51, 52) have a higher modulus of elasticity, while the intermediate section (53) has a lower mass density, which effectively raises bending resonant frequencies above the spectrum test frequencies.

摘要： A multi-cylinder hot gas engine having an equal angle, V-shaped engine block (11) in which two banks of parallel, equal length, equally-sized cylinders (12) are formed together with annular regenerator/cooler units (13 and 14) surrounding each cylinder, and wherein the pistons (17) are connected to a single crankshaft (23). The hot gas engine further includes annularly arrayed heater tubes (27) disposed around a central circular combustor volume (37). Balanced-flow expansion manifold assembly (15) and regenerator manifold assembly (16) provide optimum balanced flow of the hot working fluid through the heater head tubes which are connected between each pair of manifolds and their respectively associated cylinders and annular regenerator units. This balanced flow provides even heater head temperatures and, therefore, maximum average working fluid temperature for best operating efficiency with the use of a single crankshaft V-shaped engine block.

摘要： A lubricated piston rod seal (21) which inhibits gas leaking from a high pressure chamber on one side of the seal to a low pressure chamber on the other side of the seal. A liquid is supplied to the surface of the piston rod (22) on the low pressure side of the seal. This liquid acts as lubricant for the seal and provides cooling for the rod. The seal (21), which can be a plastic, elastomer or other material with low elastic modulus, is designed to positively pump lubricant through the piston rod/seal interface (26, 28) in both directions when the piston rod (22) is reciprocating. The capacity of the seal to pump lubricant from the low pressure side to the high pressure side is less than its capacity to pump lubricant from the high pressure side to the low pressure side which ensures that there is zero net flow of lubricant to the high pressure side of the seal. The film of lubricant (29) between the seal (21) and the rod (22) minimizes any sliding contact and prevents the leakage of gas. Under static conditions gas leakage is prevented by direct contact between the seal (21) and the rod (22).
