  • Ski suspension
    Patent number: 4979761
    Abstract: A suspension for skis including a pair of vertically spaced plates, the lower plate being mounted to the ski and the upper plate having a boot attached thereon. Compression springs interposed between the suspension plates absorb shock and impact, and the suspension includes lateral alignment stabilizers and pivoted links interconnecting the plates which permit vertical movement but restrain the plates against lateral angular variations whereby the pressure applied to the ski edges is maintained during vibration absorbing. A foam material between the plates damps the suspension action and protects the interior components.

  • Air controlled rotary joint compensator
    Patent number: 4971367
    Abstract: The invention pertains to the method and apparatus of compensating for the axial bearing load forces imposed upon rotary joints conveying a pressurized fluid medium, such as steam, by imposing an axial force on the rotary joint housing proportional to the pressure within the rotary joint by use of a distinctively different pressurized medium than that conveyed by the joint, such as compressed air. An expansible chamber motor capable of imposing an axial force on the rotary joint utilizes compressed air whose pressure is controlled by a sensing and regulating system responsive to the pressure within the rotary joint.

  • Wing fold frangible valve
    Patent number: 4971096
    Abstract: A reconnectable frangible coupling wherein at least one coupling part includes an operating valve and a safety valve. The operating valve utilizes the relative axial movement of the coupling parts during coupling and uncoupling to open and close, respectively, and the spring biased safety valve is engaged and retained in an open position by a valve retainer interposed between the valves. Frangible portions maintain the valve retainer in engagement with the safety valve and upon the coupling being subjected to severe impact, such as an aircraft crash, the frangible portions fracture permitting the valve retainer to disengage from the safety valve allowing the safety valve to close.
