Larry F. Brauer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4526104
    Abstract: A safe-arm device for use in a fuel-air explosive munition carried by an craft. The device has a housing having an environmental seal which is separated from the housing upon munition release to form a seal opening, a pressure probe for obtaining static and dynamic air pressure and extending through the seal opening when deployed, a piston and rod which is driven upon sensing of a sufficient differential air pressure between the static and dynamic air pressure probe, a safety lock which locks a pyrotechnic rotor and which disengages upon full extension of the piston rod, and an arming spring which is compressed by extension of the piston rod and which drives the pyrotechnic rotor for rotation against a mechanical escapement device thus providing for a timed rotation. The pyrotechnic rotor has two explosive wheels, each having switched detonators and upon receipt of electronic signals two explosive trains with a controlled time delay therebetween are initiated.

  • Patent number: 4489656
    Abstract: A test operable electro-mechanical safe and arming mechanism for hardened rget penetrating, and other, ordnance, not relying on stored energy, incorporating two mechanical interlocks and providing an electro-mechanical elapsed time reference and mechanical logic to check external control apparatus operation comprises a body having a reversible motor which drives a rotatable shaft having ends threaded in opposite directions. The shaft penetrates the threaded holes of three members which move axially depending on the direction of shaft rotation. The middle member is an initially misaligned explosive train component configured to engage one threaded shaft end to advance into the aligned or armed position. A ball interlock maintains this component misaligned until ordnance delivery is sensed at which time motor energization occurs in a first direction to cause shaft rotation and to preposition the mechanism for arming.

  • Patent number: 4478147
    Abstract: A safety arming device driven by a reversible motor including a detonator sitioned in a casing for initiating explosive logic through the reception of signals from an electric circuit. A driver wheel is rotated by the reversible motor which matingly engages a driven wheel. The driven wheel includes a groove into which a guide pin from the driver wheel moves and the driver wheel rotates through a predetermined angle to align detent slots at a latching position. There is provided an output wheel having gear teeth and explosive output leads, and upon the alignment of the slots in the latching position, the latching mechanism engages the driver/driven wheels, and upon further rotation the wheels are enmeshed to rotate the explosive output lead to an alignment position with the detonator.

  • Patent number: 4188886
    Abstract: An air pressure sensing probe for providing static-dynamic differential air ressure to operate a guided missile warhead safety-arming device is disclosed. The probe assembly is hermetically sealed to keep the device free of dirt and moisture during storage. An electrically initiated squib, fired at a predetermined time after missile launch, supplies gas pressure to the base of the probe which acts as a piston. The probe breaks a tip seal, extends laterally out from the missile, and wedges into the erect position. The base of the probe contacts a sliding punch which severs seals from two air pressure conduits and aligns air passageways with static and dynamic pressure ports in the probe. Differential air pressure is thus fed to a safety-arming device which utilizes pneumatic operation.
