  • Patent number: 6158390
    Abstract: A pet ball which is formed from two (2) hollow semi-spherical half members and which is readily mobile along a hard surface, for example the ground. A weight, for example, a fishing sinker, is suspended within the pet ball. The weight is suspended by an elastic member, for example, an elastic rubber band, which is attached to the inside wall of the pet ball. The weight can be attached to the elastic member in such a manner that it can move along the elastic member or it can be fixed at a stationary position along the elastic member to create different desired effects. When a force is applied to the pet ball, it will roll. With the weight being suspended from the elastic member, the center of gravity of the pet ball changes as the pet ball rolls, thus resulting in erratic movement or a path which follows no definite or consistent direction or pattern.

  • Patent number: 6138421
    Abstract: The invention relates to an apparatus for supporting and positioning an anchor bolt within a masonry construction block wall to allow the frame of a building to be secured or tied to the anchor bolt. Masonry construction block walls are typically constructed so that the hollow vertical cores in the construction blocks are partially aligned so as to form a hollow channel or conduit traveling down through the wall. The apparatus includes a base designed to fit within a construction block wall to provide a support to which the lower end of an anchor bolt may be attached by clips or otherwise. This allows the upper end of the anchor bolt to extend upward through the channel and above the top layer of blocks. The base also serves to plug or fill the channel formed by the cores in the blocks so as to facilitate the process of permanently securing the anchor bolt by pouring cement into the channel around the anchor bolt.

  • Patent number: 6135681
    Abstract: The present invention is a drilling system for cutting flat bottomed holes in work pieces. The tool has two opposing angled cutting edges extending from a rotational axis, with the inner portions of these cutting edges extending upwardly to create an overlapping web at the center. The overlapping web strengthens the center portion of the cuttings edges of the tool. The angle at which the inner portion of the cutting edge is inclined can be increased to create a center point on the cutting surface of the tool. The center point adds stability to the tool as it rotates along its longitudinal axis. The cutting edge has a rake surface with a positive rake angle that lessens the forces on the insert and also allows for better formation of chips of stock material being removed. Chip breakers can be cut into the cutting edges of the insert, further aiding in the removal of stock material.

  • Patent number: 6123175
    Abstract: Interconnected vents for a motor vehicle axle assembly, transmission or transfer case which interconnects multiple vents at different locations together with another vent positioned at the highest point the lubricant travels. This allows the lubricant to flow out of one vent and return to the other vent without leaking onto the ground. Such an interconnected vent arrangement will minimize the extent of external lubricant leakage due to such factors as foaming of the lubricant, air entrapment in the lubricant, volumetric expansion of the lubricant due to elevated operating temperatures, pumping or splashing of the lubricant by internal rotating or moving parts, flow of the lubricant due to tilting of the motor vehicle, and thus the motor vehicle axle assembly, transmission and transfer case, and/or acceleration or deceleration of the motor vehicle.
