  • Burst-pressure test fixture for pressure vessels dynamic rocket motors
    Patent number: 4356720
    Abstract: A method for burst testing a vented pressure vessel accurately measures the rue burst pressure of the vented pressure vessel. The method employs a burstpressure test fixture which comprises a plug and a gauge adapter member for substantially plugging the vent opening in a pressure vessel to be burst tested. The plug and gauge adapter member is adapted for receiving a transducer or pressure gauge that is integrally mounted with a pressure gauge tube which is insertably mounted in the plug and gauge adapter member. The vent opening which is substantially plugged with the tube member of the plug and gauge adapter member is free from stress during pressurization to burst pressure. The method requires that the plug and gauge adapter member be stationary, but the vented pressure vessel is allowed to move outwardly along the tube member during dynamic testing. The fit of the plug to the vent opening (i.e.

  • Dual rate firing mechanism
    Patent number: 4355563
    Abstract: A dual rate of fire mechanism in an automatic weapon absorbs and dissipates portion of the recoil energy to produce a slow firing rate and inactivates the energy absorbing elements to produce a rapid firing rate. Compression of a recoil spring stores the recoil energy of the weapon bolt and normally returns substantially all of the energy to the bolt in a counter recoil portion of the cycle. In slow firing mode, some of the energy stored in the recoil spring is dissipated in a positioning spring thus providing less energy to the counter recoil action and slowing the rate at which succeeding rounds are fired.

  • Contactless resistivity measurement method and apparatus
    Patent number: 4353027
    Abstract: Methods and apparatus for contactless, non-destructive resistivity measurnts on semiconducting crystalline material, for example gallium arsenide. The material to be tested is formed into a disc which is supported within an air gap. The holder for the disc is such as to support the disc only about its outer edges; thus, the disc is free to vibrate piezoelectrically. A measuring circuit connected to the electrodes, which establish the air gap, applies an alternating electric field in the air gap which causes the crystal to vibrate. By adjusting the frequency of excitation, resonance may be established in the crystal and by comparing the current drawn through the air gap with graphs previously established for material of the type under test, the resistivity of the disc can be determined.

  • Lighter than air wind energy conversion system
    Patent number: 4350897
    Abstract: A lighter-than-air (LTA) wind energy conversion system (WECS) wherein the LTA envelope carries a main rotor and electrical generator to take advantage of high wind speeds available at high altitudes. The LTA envelope is tethered to a ground based mooring system designed to provide self-orientation for the LTA envelope. In a preferred embodiment, heavy mechanical transmissions are eliminated by providing a hollow bladed main rotor which drives an induction turbine positioned within a substantially linear duct which is, in turn, preferably located along the longitudinal axis of the LTA envelope. The output of the induction turbine is coupled to an electrical generator whose output is, in turn, transmitted to the ground via the tethering system.

  • Lighter than air wind energy conversion system utilizing an internal radial disk diffuser
    Patent number: 4350896
    Abstract: A lighter-than-air (LTA) wind energy conversion system (WECS) wherein the gas-filled LTA envelope carries a main rotor and electrical generator to take advantage of high wind speeds available at high altitudes. The LTA envelope is tethered to a ground based mooring system designed to provide self-orientation for the LTA envelope. In a preferred embodiment, heavy mechanical transmissions are eliminated by providing a radial disk diffuser within the LTA envelope coupled through a drive shaft to a wind-driven external rotor. Rotation of the rotor-diffuser drives an induction turbine positioned within the gas inlet to the diffuser, the lifting gas for the envelope also serving as the working fluid for the turbine. The output of the induction turbine is coupled to an electrical generator whose output is, in turn, transmitted to the ground via the tethering system.

  • Lighter than air wind energy conversion system utilizing an external radial disk diffuser
    Patent number: 4350898
    Abstract: A lighter-than-air (LTA) wind energy conversion system (WECS) wherein the LTA envelope carries a main rotor and electrical generator to take advantage of high wind speeds available at high altitudes. The LTA envelope is tethered to a ground based mooring system designed to provide self-orientation for the LTA envelope. In a preferred embodiment, heavy mechanical transmissions are eliminated by providing a radial disk diffuser coupled to a main rotor which, upon rotation, drives an induction turbine positioned within a substantially linear duct which is, in turn, preferably located along the longitudinal axis of the LTA envelope. The output of the induction turbine is coupled to an electrical generator whose output is, in turn, transmitted to the ground via the tethering system. In an alternate embodiment, the main rotor may itself be ducted.

  • Device to de-spin objects with very high spin
    Patent number: 4350315
    Abstract: A method and apparatus are disclosed which are particularly adapted to quickly de-spin a rapidly rotating object or projectile. Weights are released from the object in a series of distinct stages, thus discarding enough momentum to reduce the spin of the object to a desired minimal value. The weights are released simultaneously by a single release means thereby assuring perfectly symmetrical and synchronized release of the respective weights. The result is a pure de-spin of the object without imparting other motion to the object.
