  • Patent number: 5027737
    Abstract: A power driven tracked amphibious vehicle is disclosed for moving troops from ships to shore at speeds in excess of 25 miles per hour. The vehicle includes a pair of hydrofoil assemblies each pivoted to the vehicle for movement between an operative water mode position with the hydrofoils and inline water jet propulsion units submerged in water for propelling the vehicle while in water, and a land mode with the hydrofoils and water jet propulsion units raised above the tracks for propelling the vehicle on land. When in the water mode the tracks are raised a short distance, and the track covers and bow flaps are positioned below the tracks for minimizing drag on the vehicle.

  • Patent number: 4993977
    Abstract: A water jet propulsion module is generated about a central axis and has an inlet opening and a discharge opening concentric with said axis. The module includes a stator having an inner wall and an outer wall with curved stator vanes connected between said inner and outer walls. An impeller shroud is adjustably connected to the outer stator wall. A motor secured to the stator drives a planetary gear drive attached to an impeller by a parabolic impeller cone. The impeller draws water into the inlet opening and drives the water past the stator vanes out of the discharge opening along a substantially linear path at high speed and pressure.

  • Patent number: 4994637
    Abstract: A single turn induction coil which provides uniform sealing of lids to plastic containers. A first end of the coil overlaps a second end of the coil with the ends being tapered to form a single complete ring. An electrical current is coupled to the overlapped portions of the first and second end of the coil so the electrical current flows for more than 360.degree. around the coil. This provides an induced electrical current around a container lid adjacent to the coil and provides heating of the complete circumference of the lid. A variety of shapes of containers and matching lids can be used with the present invention.

  • Patent number: 4952154
    Abstract: Devices for demonstrating the effect that eccentricities in a tire and rim can have when the combination is rotated having a circular member representing a rim mounted for rotation about a center different from its geometric center and an annular member representing a tire with a varying radial dimension is positioned and retained at a plurality of angular positions on the circle member. An indicator operatively associated with the annular member represents the resulting eccentricity of both members.

  • Patent number: 4944141
    Abstract: A height control system is disclosed for use on a harvester and includes at least one lightweight wheel which rides over the crop being harvested at a location forwardly of the vehicle in an undisturbed area of the crop without damaging the crop. The wheel detects upward or downward inclined portions of the ground and controls power means which raises or lowers at least one plant handling component of the harvester for maintaining the component at the desired elevation relative to the ground. The system also includes control means which sense varying ground speed and prevents undesirable jerky raising and lowering of the conveying components in response to the wheel riding over small articles such as rocks at different speeds.

  • Patent number: 4939042
    Abstract: The outer surface of an elongated metal component such as a bar is rapidly heated by an induction coil and is thereafter cooled by a quenching spray while being subjected to tensile forces so high that the center portion of the bar approaches yield causing the bar to elongate slightly. The tension on the bar is released thereby obtaining high residual compressive surface stresses in the cooled outer layers of the bar which define an annulus and which shortens the bar slightly until compressive stresses in the surface layers equal the tensile stresses acting on the central sections of the bar thereby greatly improving the fatigue life of the bar.
