John A. Condon - Timonium MD, US
Timothy Brosseau - Havre De Grace MD, US
David Lyon - Street MD, US

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

F41C 27/06

US Classification:

42105

Abstract:

A launcher system and method for an unmanned aerial vehicle (UAV), wherein the launcher system comprises a barrel comprising a prepackaged internal pusher cup configured behind the UAV housed within the barrel; an expansion chamber operatively connected around the barrel, wherein the barrel extends out of a first end of the expansion chamber; a muzzle adapter operatively connected to a second end of the expansion chamber, wherein the first end of the expansion chamber is positioned opposite to the second end of the expansion chamber; a rifle slip-fitted to the muzzle adapter; and a stand operatively connected to the expansion chamber, wherein a triggering of the rifle causes the internal pusher cup to push the UAV out of the barrel at a predetermined launch velocity in order to attain a predetermined self-propelled flight trajectory.

David Lyon - Belcamp MD

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

F41C 900

US Classification:

273 84R

Abstract:

A police baton sidearm having a baton main body and a crosshandle which is ttached in a perpendicular manner to the baton main body at a position longitudinally displaced from the geometric center of the baton main body. The baton main body also houses a recessed trigger ahead of the crosshandle and means for launching a projectile. In order to achieve impact insensitivity a double action only firing mechanism is employed. The baton main body is constructed in two parts to accomodate breech loading and various connection schemes including interrupted and multilead threads on abutting portions of the baton main body. Guide rods or a hinge mechanism may be provided to accomodate one-handed loading. The police baton sidearm may also be equipped with gunsights and a laser pointing device for improving the accuracy of the user's aim.

International Classification:

F41B 1106

US Classification:

124 57

Abstract:

Apparatus for a gas charged and initiating mechanism launches a projectile f a relatively low mass at a low velocity. The apparatus has a chamber which has an opening at one end. A burst diaphragm is seated within this opening and seals it. The opening also houses the projectile. A check valve is mounted in an aperture at the opposite end of the chamber. The compressed gas is charged through the check valve. The bursting of the diaphragm is accomplished by a pointed rod protruding from the rear of the projectile or by an electrically-powered squib associated with the diaphragm. The bursting of the diaphragm provides a quick-acting means for releasing the compressed gas whereby the projectile is accelerated down the barrel of a weapon. Additionally, a safety device is mounted within the cartridge for preventing the accidental functioning of the launching projectile.
