  • Publication number: 20240032502
    Abstract: An animal feeding bucket an animal feeding bucket includes a container, a locking system, and a base plate. The container has a top edge, a bottom, and sidewalls. The base plate includes spike holes therethrough. The base plate also includes mounting spikes extending through the spike holes. The locking system includes a first locking member coupled to the base plate and a second locking member coupled to the container bottom. The first locking member has four inverted L-shaped locking flanges having vertical walls and an inwardly extending top walls. The locking flanges define lock recesses. The second locking member has four radially and outwardly extending locking tabs. Each locking tab is configured to be received within a lock recess of one locking flange to interlock the locking tab with the locking flange.

  • Publication number: 20230235720
    Abstract: 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.

  • Publication number: 20160146578
    Abstract: 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.

  • Patent number: 7845266
    Abstract: 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.

  • Patent number: 7806038
    Abstract: 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.

  • Patent number: 6722195
    Abstract: 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.

  • Patent number: 6675488
    Abstract: 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.
