Publication number: 20230235720Abstract: A vehicle engine heater includes a heat generator or heater portion and a heat distribution portion. The heater portion includes an external housing defining an interior air channel therethrough extending from an intake port to an exhaust port. An electric fan and heating elements are mounted within the air channel. The electric fan and heating elements are coupled to an electric power cord having a controller to control the electricity flowing to the electric fan and heating elements. The heat distribution portion includes an elongated main conduit and a base having a pair of legs includes two laterally opposed feet. The main conduit has a series of air openings extending from the central channel to a top surface. The open end is coupled to the housing of the heater portion at the location of the exhaust port.Type: ApplicationFiled: January 21, 2022Publication date: July 27, 2023Inventor: Leslie P Duke

Publication number: 20160146578Abstract: Polymeric compositions for use in preparing a ballistic material and ballistic materials capable of absorbing incoming projectiles prepared from the polymeric material are disclosed. The resulting ballistic materials are also disclosed. The materials have sufficient elasticity so that the polymer or polymer blend does not shatter when stuck with a high-velocity projectile. The polymer blends ideally have one or more of the following physical properties—a) a modulus of elasticity in the range of around 12,500 psi and around 19,000 psi, b) a max stress psi in the range of around 545 and around 985, and c) a tensile strength in the range of around 3.50 ft-lbf/in and around 11.00 ft-lbf/in. The thickness of the ballistic material is at least around 3 inches, with a size of around 4-5 inches square or diameter. Objects made of a hardened material, typically between about ¼ and ½ inch, can be interspersed throughout the interior volume of the material.Type: ApplicationFiled: June 30, 2015Publication date: May 26, 2016Inventors: Leslie P. Duke, Wayne Barrett

Patent number: 7845266Abstract: A building block for constructing a projectile absorbing armor. The building block has at least one interlocking male connector and at least one female connector. The interlocking male connector and said female connector are sized for interlocking engagement. The invention is also generally directed to a structure having projectile absorbing armor having at least two building blocks in interlocking engagement. The building blocks are constructed from projectile resistant material and may have various features to prevent the passage of a projectile through the block.Type: GrantFiled: January 8, 2007Date of Patent: December 7, 2010Assignee: Ballistics Blocks LLCInventors: Leslie P. Duke, Wayne Barrett

Patent number: 7806038Abstract: A building block that can be assembled into structures without requiring special end or corner pieces. The block has top and bottom surfaces that contain a cooperating projection and slot for stacking the blocks. Two end surfaces and two side surfaces complete an enclosed volume. One side and one end surface has at least one interlocking male portion. The other side end surface has at least one cooperating slot portion into which the male portion fits to interlock the blocks.Type: GrantFiled: July 13, 2005Date of Patent: October 5, 2010Inventor: Leslie P.

Patent number: 6722195Abstract: A method and apparatus for trapping projectiles so that the projectiles are not damaged is disclosed. An elongated trough is typically filled with alternating layers of a foam substance and a fibrous substance. Alternatively, the trough can be filled with just a foam or fibrous substance. A projectile launcher such as a gun is connected to the trough and a projectile is shot into the filling substance substantially parallel a longitudinal axis of the trough. The trough can be opened and the projectile can be recovered from the filling substance.Type: GrantFiled: June 20, 2002Date of Patent: April 20, 2004Inventor: Leslie P. Duke

Patent number: 6675488Abstract: An alignment apparatus, system and method of alignment for motorcycle is disclosed. The apparatus typically includes an elongated threaded rod and two internally threaded cones that screw onto either end of the rod in opposition. The alignment system typically includes two of the apparatuses, one to be fitted within the rear axle and the other to be fitted within the swing arm pivot shaft. The distance is measured between the ends of the rods on either side of the motorcycle and the rear axle is adjusted until the distances are equal. The rear wheel is then in alignment with the motorcycle.Type: GrantFiled: March 28, 2002Date of Patent: January 13, 2004Inventor: Leslie P. Duke
