Abstract: A three-dimensional life-size game animal-simulating archery target including a foam body shaped in the form of a game animal, such as a deer, elk, moose, bear, wild boar, etc., and having a target insert receiving recess located in a primary aiming point of the target. A removable target insert adapted for use with broad head arrows, field point arrows, or both, is releasably secured in the recess in the foam body, and a removable body cover placed over the insert and recess to provide a uniform visual appearance to the exterior of the game animal. A three-dimensional game animal archery target system includes a foam body shaped in the form of a game animal together with at least two removable target inserts, one being adapted for use with broad head arrows and the other being adapted for use with target point or field point arrows. Such a system provides the user with the ability to utilize the same target for archery target practice and hunting preparation with both field point and broad head arrows.

Abstract: A drill bit including at least one rolling cutter body with rows of relatively hard substantially outwardly projecting and circumferentially spaced cutting inserts projecting from the cutter body and having effective erosion reducing features by application of hardfacing materials placed in oriented regular patterns and shapes on designated critical and vulnerable cutter body areas. The cutter body is produced by a method wherein the body is marked in specific locations of desired patterns, shapes, or boundaries, and, then, hardfacing is applied in these specific boundaries to avoid the insert hole locations. After the hardfacing is permanently bonded to the specified areas, the holes are drilled and the hard cutting inserts are pressed into the holes.

Abstract: A filtering system with electrolytic action and method is disclosed which is adapted for filtering the water in swimming pools, spas, saunas, hot tubs, whirlpools and the like. The filtering system includes a pump for drawing water from a body of water and circulating this water through an electrolytic filter including a layer of electrolytic filter media of dissimilar metal particles or granules and returning this filtered water to the body of water. The filtering system not only removes sand and sediment but also prevents algae and fungus growth, kills bacteria, and eliminates the need for adding chlorine, bromine, and algacide to the water. In accordance with a preferred embodiment, the filtering system includes a bypass valve installed downstream of the pump to divert only a selected quantity of water through the electrolytic filter.

Abstract: A self-contained oil spill cleanup craft and method which operates well in both rough and calm seas, is rapidly deployed, which provides high flow rate continuous separation and processing of recovered oil and water mixtures, and outputs water which is substantially free of oil and oil which is substantially free of water and other contaminants and, as such, refinery ready without further processing. The craft of the present invention can be used, for example, to clean up light and medium weight crude oil, lubricating oil, or diesel fuel that is floating on the surfaces of either fresh or salt water.

Abstract: A well strainer is provided which includes a plurality of stacked, annular, filter segments with each segment including a plurality of elongate, arcuate, threaded rod receiving slots, ramped bearing surfaces near each slot, and position indicators in the vicinity of the ramped bearing surfaces and slots. The gap between adjacent annular filter segments is selected by rotating one segment relative to another to a desired position whereat indicator points are received within respective indicator sockets. Guide members adjacent the ramped bearing surfaces help to keep adjacent filter segments in true superimposed relation.

Abstract: There is disclosed a catheter device with easily deployed retainer useful in securing medical appliances such as catheters, sensors, tubing, or the like, to a human or other patient. The device includes a catheter, or the like, with a self-adhesive tape which is attached and extends perpendicularly thereto. The self-adhesive tape may be a strip of conventional surgical or first aid adhesive tape and has each of its ends rolled towards the catheter in a scroll-like fashion; the tape preferably is pre-attached to the catheter by adhesive, heat sealing, or the like, and may have a medicine saturated pad on the bottom side to help prevent infection at the wound area. The adaptation of the device with any intravenous catheter does not change standard use in any way in relation to preparation of the site, or actual insertion of the catheter. After the vein has been accessed, the tape is simply unrolled by the thumb and index finger with moderate pressure to secure the catheter to the patient's skin.

Abstract: A method and apparatus for recovering torque lost due to joint relaxation in threaded fastener assemblies or joints. The present invention is especially adapted for use with medium-to-short or gasketed joints. In the practice of an exemplary embodiment of the invention, the torque of an electric nutrunner is pulsed at the end of a fastener tightening cycle between programmed maximum and minimum torque values which have been selected to overcome the static to dynamic torque ratio of the joint while maintaining the motor and gearing of the nutrunner in a loaded condition to ensure maximum nutrunner durability.
