Abstract: A two part tool (33, 34) fits into the crankshaft bore (16) of a partially manufactured connecting rod (11) for an internal combustion engine and expands the bore (16) to break the bore housing (13) into two pieces (14, 15), one of which comprises a bearing cap (15) to permit installation of the rod onto a crankshaft journal. The tool (33, 34) is retracted to fit within the bore (16) for the bearing and a high pressure acts on a piston (50) to provide a high enough force to move the two parts (33, 34) of the tool away from each other in direction perpendicular to a bisecting plane that lies along the central axis of the bore (16) and to split the one piece bearing housing (13) into two parts along a plane defined by notches (22) which weaken the bearing housing (13) in selected areas. The piston (50) is centered on the bisecting plane of the connecting rod (11) so that the forces are balanced to ensure uniform, repeatable operation. The movement (displacement) of the tool portions (33, 34) and the load on the tool portions are both sensed for control of the test, and also to permit obtaining data on load and displacement relationship for quality control of the parts.

Abstract: A brake torque loading linkage (51, 53, 91, 121, 127) for vehicle spindle test fixtures (10) permits applying a brake torque load while other loads are being applied, particularly vertical loading, where substantial movement is encountered, without requiring substantial compensation. The brake torque loading actuator (121, 127) is mounted to move with the vertical loading linkage. The reference for the brake torque is thus on the linkage (50, 101) that moves for applying the vertical load and there is no need to compensate for vertical movements of the spindle (11) being tested when applying the brake torque.

Abstract: An extensometer readout circuit conditions a strain information signal (at terminals 36, 38), representing strain of a specimen (18) being tested, in such a way that yield point measurements and final elongation measurements of such specimen may be concurrently obtained. The strain information signal (36, 38) is provided by subjecting the specimen (18) to a tensile or compression test by any conventional means known in the prior art. The strain information signal (36, 38) is first applied to a preamplifier (40). The preamplified strain information signal is then concurrently applied to both a high gain amplifier (42) and a low gain amplifier (44). The signal obtained from the high gain amplifier (42) is used for performing modulus calculations and for obtaining yield point measurements. The signal obtained from the low gain amplifier (44) is used to obtain the total elongation measurement.

Abstract: A "mode switch" (45) is used for smoothly switching a servovalve controlled device such as an SMC press (10), in particular, from control under one parameter to control by another. The mode switch (45) provides a very smooth transfer of control from displacement control (47) between two relatively movable parts (20, 23) to force control (46) to provide for controlling the force exerted by actuators acting between the two parts (20, 23). The mode switch (45) electronically tracks the signals so that when the switching (64, 65) is made the signals are precisely equal to prevent abrupt changes in the control signals. This smooth transfer is achieved even under active control, that is when both control signals are changing in value.

Abstract: A waveguide suspension device (2) and modular construction for sonic waveguides (4), including a damping element (6) for use with a waveguide (4) that supports a current pulse and results in a torsional or longitudinal strain wave, is also disclosed. The damping element (6) is to prevent the reflection of the sonic strain wave and includes a sleeve (27) surrounding the waveguide and a mechanism (29) for applying pressure on the sleeve (27) so the sleeve (27) exerts pressure on the waveguide (4), thereby gradually dampening the sonic strain wave energy along the length of the waveguide (4) surrounded by the damping element sleeve (27) to prevent reflection of the sonic strain wave. Further, the return conductor (1) placement is determined by measuring system response to provide minimal ringing of the signal received from a pickup coil (13). In addition, the suspension mechanism (2) is used to contain the waveguide thereby avoiding extraneous noise. A bracket (10) is disclosed that facilitates the process of assembly of the waveguide assembly. Also, a local buffer circuit for use with a magnetostrictive transducer is disclosed wherein the magnetostrictive transducer (4) includes a pickup coil (13) and the local buffer circuit includes two diodes (22, 23) in parallel with the pickup coil (13) to clip or short the energy produced in the pickup coil (13) generated by an interrogation pulse, and also includes a common emitter amplifier (24) to reduce the electrical impedance of the pickup coil (13), also in parallel with the pickup coil (13).

Abstract: A feedback control system (100, 150) modifies a drive signal (35) to a plant (51) providing an achieved response signal (52). An adaptive filter (34) adjusts a response error signal (106), representing the difference between a desired response signal (13) and the achieved response signal (52), in accordance with a dynamic behavior to provide a drive correction signal (108). A compensator (36) adjusts the dynamic behavior in response to the drive signal (35) and the achieved response signal (52). A storage device (54) delays a corrected drive signal (112) representing the sum of the drive signal (35) and the drive correction signal (108). A converter (102) provides the modified drive signal (35) based on the delayed corrected drive signal.
