  • Bowstring release apparatus
    Patent number: 5435291
    Abstract: A bowstring release apparatus having a housing and a release arm projecting from the housing. A flexible cord is secured with respect to the release arm and thereby forms a gap between the release arm and the flexible cord, when the bowstring release apparatus is in a loaded position. Upon release of the flexible cord with respect to the release arm, the bowstring release apparatus moves from a loaded position toward an unloaded position. A longitudinal axis of the release arm is positioned generally parallel to a direction of travel along which a bowstring moves, when the bowstring release apparatus moves from the loaded position to the unloaded position. Contact between the flexible cord and the bowstring preferably does not exceed an approximately 90.degree. arc section of an outer circumferential surface of the bowstring.

  • Scaleable process for producing Ni-Al ODS anode
    Patent number: 5429793
    Abstract: A process for producing metal oxide dispersion-strengthened anodes for use in fuel cells in which a metal alloy powder comprising at least one metal powder and at least one metal oxide forming phase is formed into a "green" cohesive structure. The "green" cohesive structure is heated in a sintering furnace resulting in simultaneous sintering and internal oxidizing of the oxide forming phase within the "green" cohesive structure, forming an oxide dispersion-strengthened structure. To promote simultaneous sintering of the "green" cohesive structure and internal oxidation of the oxide forming phase within the "green" cohesive structure, an oxidizing agent is disposed within the "green" cohesive structure or is applied to the exterior of the cohesive structure.

  • Apparatus and method for force-controlled fatigue testing
    Patent number: 5396804
    Abstract: An apparatus and method for force-controlled fatigue testing of a specimen or material. A driver is used to generate a load force which is applied to the test specimen. Physical property changes of the test specimen are measured over time and a feedback signal is generated as a function of the measured physical property changes. A motion command signal is computed as a function of the feedback signal. A computer processes the feedback signal and emits the motion command signal to an actuator. The driver responds to the motion command signal and maintains the load force at an approximately constant magnitude during the physical property changes of the test specimen.

  • Method and apparatus for artificially stimulating cough reflex
    Patent number: 5397337
    Abstract: A method and apparatus for eliciting a physiologically significant cough reflex, such as in a quadriplegic patient. The apparatus preferably has at least one pair of electrodes which are positioned about or near the abdominal muscles. The user generates an input signal. The input signal and a stimulus pulse signal are computed into an output signal. Prior to the delivery of the output signal, alerting signals are delivered to the user to alert the user of an upcoming cough and the onset of pulse electrical voltage to allow the user to engage appropriate volitional activity to optimally engage and complete the cough. The output signal is transformed into a pulse electrical voltage which is delivered across each pair of electrodes. Such pulse electrical voltage activates the lower motor neurons and thereby contracts the abdominal muscles to elicit a physiologically significant cough reflex.
