Abstract: A preset recessed casing block for retaining a cutter bit is provided that can be mass-produced and easily installed in the casing of a core barrel. The block has a size and shape that provides for quick and easy insertion and welding into a casing. The block has a cavity that receives and retains a cutter bit while allowing for the removal or extraction of the cutter bit when the bit becomes worn or broken. Because the block is manufactured to fit inside the casing, wear on the block is minimized and it's lifetime extended. The cavity in the block and the shape of the block itself may have different, preset angles and pitches, to allow for the same size block to be placed in a variety of locations around the casing, thereby enabling the manufacturer to produce a variable, raking pattern of the cutter bits for improved annulus cutting.

Abstract: Pocket protecting retainable cutter bits used on various mining, excavating, and foundation drilling tools and equipment are disclosed. The invention includes a combination of one or more free spinning wear rings axially mounted in recessed portions of the cutter bit shank and a groove and snap ring retainer. The wear rings are tapered on at least one end to assist in installation and designed to compress as the cutter bits are installed into cutter bit pockets. These wear rings are designed to protect the inside surface of the pocket by acting as a barrier between the spinning cutter bit and the stationary inside surface of the pocket. The cutter bit shank is longer than the cutter bit pocket and when installed passes through the pocket and extends past the axial length of the pocket. A flange is included with the cutter bit to protect the outer surface of the pocket.

Abstract: Environmentally-friendly tamper-evident safety closures used on various containers and are optionally personally identifiable are disclosed. The invention includes a combination of a semi or fully perforated retaining ring and cap, and an un-perforated section between the two that acts as a tether keeping both pieces from separating after the tamper evident perforations have been broken loose. The tether portion is designed to stretch without breaking to allow the removal of the cap from the bottle.
