  • Patent number: 4748571
    Abstract: A line-up vision system for testing the alignment of a workpiece in a holder of an automated machining apparatus. A light source illuminates one portion of the workpiece and keeps another portion of the workpiece dark. A light colored backdrop provides a sharp edge along the dark portion of the workpiece for a camera directed toward the backdrop. As the workpiece is rotated slowly the camera observes any movement of the sharp edge to determine if the workpiece is properly positioned in the holder of the machining apparatus. If the workpiece is properly positioned the camera provides signals which cause the apparatus to proceed with machining operations on the workpiece.

  • Patent number: 4732579
    Abstract: A system and method provides a continuous supply of clean air at a desired temperature to the crew members of a combat vehicle when in an environment contaminated by nuclear, biological or chemical warfare agents. The contaminated air is initially compressed by energy received from the exhaust gases from a combustion power unit of the vehicle, the initially compressed air is then cooled to increase its density and is then compressed and cooled a second time before being passed through a pressure swing adsorbent system which continuously removes all known contaminants from the air, and is then expanded and changed in temperature to provide clean air at a desired temperature to personnel within the vehicle. The energy released from the air during expansion is used to compress the air the second time thereby providing a very energy efficient system.

  • Patent number: 4706494
    Abstract: Disclosed is an apparatus and method for testing the integrity and acceptability of the seal of a package before or after it has been sterilized by any chosen conventional process which may include heat sterilization of a sealed package, aseptic packaging or irradiation. Testing is accomplished by subjecting the package or container to a controlled external pressure, preferably a linear actuator, sufficient to create a selected level of internal pressure. Any suitable means may be used to determine the rate of pressure change within a selected time interval. Upper and lower limits of pressure change determine whether the seal is acceptable.

  • Patent number: 4702731
    Abstract: Disclosed is a mechanism, associated with a thermoplastic bag making machine, for preparing a strip of thermoplastic to produce bags having the upper edges of the bag mouth formed in a sinusodial shape such that the peak of such shape is substantially equi-distant relative to the side edges of the bag. While the disclosed bag machine is of the type that advances the web strip incrementally, shaping of the web strip in the sinusodial shape occurs while a portion of the web strip is advanced at substantially constant velocity. A mechanism is provided for maintaining constant tension in the web despite the constant and intermittent feeding of the web.

  • Patent number: 4700609
    Abstract: An autoloading method and apparatus is disclosed for a turret mounted gun that is pivoted horizontally relative to the turret and must be lowered to a substantially horizontal 0.degree. position for loading selected cartridges from a magazine conveyor, ejecting empty cartridge cases and misfired cartridges from the gun and turret, assisting in replenishing cartridges from outside the turret into the magazine, and off-loading cartridges from the magazine. A partition divides the turret into two compartments with a gunner and a commander located in one compartment and the mechanical components of the autoloader and breech of the gun located in the other compartment. When the gun is returned to the 0.degree. position for ejecting an empty case, the site of the director system remains on target. The turret is preferably mounted on a military land vehicle.

  • Patent number: 4685214
    Abstract: A hand held cutting tool is disclosed for use in cutting articles, especially when the tool is to be used in confined quarters while protecting the operator from being cut by the tool. The tool includes a motor which drives the cutter only when one hand of the operator grasps the motor housing and closes a trigger. Portions of a cutter and cutter guard project out of a small housing, and the guard normally encompasses the projecting portion of the cutter. When it is desired to expose the projecting portion of the cutter to perform a cutting operation, the other hand of the operator must grip a portion of the tool remote from the exposed portion of the cutter and must actuate a valve or handle to expose and maintain the guard in the exposed cutting position.

  • Patent number: 4665518
    Abstract: A data bus system includes a plurality of serially connected active terminals configured to receive data and either retransmit the received data or transmit new data to the next adjacent terminal. The terminals are configured in a diagnostic mode to configure the system optimally at turn-on or in the event system faults occur, and are configured in a user access mode once optimum configuration is attained. The system is under control by one terminal at any one time during the diagnostic mode and any terminal is capable of being the control terminal. For operation in the user access mode a cyclic period is defined during which a portion of the period is set aside for synchronous transmissions and another portion of the period is set aside for asynchronous transmissions. Both synchronous and asynchronous users are thereby accommodated by the bus.

  • Patent number: 4662809
    Abstract: An automatic level device for sensing the height and pitch of an aircraft and for adjusting a loader platform to align with the aircraft. An umbilical cord connected between the platform and the aircraft includes a tube partially filled with mercury and having a plurality of electrodes spaced along one end of the tube. As the height of the aircraft changes the mercury contacts a different number of electrodes and the electrodes provide signals for adjusting the level of the platform and aligning the platform with the aircraft.

  • Patent number: 4649375
    Abstract: Apparatus for mounting on a crane or other construction equipment for detecting the presence of an electrical power line. A reference pickup coil mounted on an upper machinery works or other portion of the equipment generates a reference signal proportional to the strength of a magnetic field in a work area. Other pickup coils mounted on a crane boom or other portions of the equipment which may extend into closer proximity to power lines develop signals which are compared with the reference signal. When any of these signals exceed the reference signal by a predetermined amount a warning signal is developed. Coils having the proper ratio of core length to diameter and having coil winding which extend along approximately half the core length provide output signals which have a predictable amplitude.

  • Patent number: 4644785
    Abstract: Apparatus for removably connecting a strain cell to a polished rod of a well pumping unit and for preventing the development of strain cell output signals due to bending of the polished rod. The strain cell is connected to a frame member which can be clamped to the polished rod where strain cell output signals are obtained due to a change in tensile load on the rod. A pair of hinges, between the frame member and the polished rod, minimizes the development of strain cell output signals due to bending of the polished rod. The frame member can be adapted to mount on a variety of sizes of polished rods. The apparatus can be removed or replaced without the use of special skills or special equipment.
