Abstract: Apparatus for sensing and measuring the torque output of a rotary device such as a gear reduction box by inserting an especially machined or configured adaptor between the shaft bearing and the bearing mounting housing. This adaptor transducer will have strain gages mounted on it in spaced relationship so that the tangential force from the gears reacting on a shaft will produce a deflection in the adaptor transducer which will be detected by the strain gages. The strain gage signal then will be sensed, amplified and can be recorded on an analog read out type meter or monitored continuously on a pen-type recorder or other conventional instruments. The strain gages can be calibrated so the output of the recorder will convert the signal into a direct reading of the torque output transmitted through the gear reduction box.

Abstract: A pendulous, linear accelerometer having its sensitive pendulous mass assembly mounted in its casing structure by means of a pair of flexure pivot bearings. The relatively long dimension of each flexure pivot, the wide separation of the flexure pivot pairs, and the inherent cross-axis rigidity of the flexure pivots provide high resistance to cross-axis vibrations. The spherically-shaped edge surface of the cylindrical pendulous mass provides a constant annular fluid flow passageway to the trapped air (or other fluid) behind the mass during its rotary movements in response to applied accelerations along its sensitive axis. The volume of trapped fluid coupled with the resistance provided by the passageway provides critical damping for the instrument.

Abstract: A vibrator is held in contact with a structure undergoing testing, such as n airplane wing. Vibrations are distributed through the structure and structural defects such as fissures will respond by emitting an acoustic signal. The acoustic signal may occur over a wide frequency range. A pick-up having a crystal transducer also makes contact with the surface of the structure to detect acoustic emissions. The crystal has a wide band response capable of detecting structural defect acoustic emissions. The pick-up has electrical leads connected thereto so that the acoustic emissions are converted to electrical signals which may be recorded or viewed on an oscilloscope. Movement of the pick-up across the surface of the structure will help determine the location of the structural defect.

Abstract: An electronic organ includes a read-only memory which stores eight bit binary words each having a digital value proportional to the frequency of a different note. When a chord keyswitch is actuated, a corresponding chord selector controlled by a multiplexer circuit causes the randomly addressable memory to sequentially generate binary words corresponding to the frequencies of the notes forming the selected chord. Each binary word is stored in a latch associated with a different universal tone generator capable of generating any tone as controlled by the stored binary word. Each universal tone generator includes a comparator which recognizes a match between the associated latch and a counter which receives clock pulses from a single fixed frequency oscillator. The comparator resets the counter and generates an output pulse which is divided to form an audible tone signal.

Abstract: A double acting drum beater device is provided having a beater adapted to strike an adjacent drumhead once for each downward movement of a foot operated pedal, and then a second time during the subsequent upward movement of the pedal. My drum beater device comprises a beater arm arranged to swing in an arc about a rotatable axis defined by a shaft supported by mounting means, which shaft is arranged to undertake oscillatory type movements. A foot pedal having up and down operative movements is mounted adjacent the mounting means and linkage means connects a toe portion of the foot pedal to an arm secured to the shaft in an offset relation. In this way, up and down movements of the toe portion of the pedal cause the connecting linkage and the arm to move responsively and thus cause the shaft to oscillate, with the shaft rotating in a first direction and then in the opposite direction about its longitudinal axis during downward movement of the pedal.
