Abstract: A pickup drop off lock box for medical samples is equipped with a failsafe lock which will not permit the key to be removed without the lid properly positioned to permit latching. Adequate thermal insulation is provided to allow samples to be stored at temperatures of 5° F. for 16 hours. In addition, an inner liner of styrene insulation is removable/replaceable in the event it becomes worn, soiled or damaged. The failsafe lock has potential applicability in other environments.

Abstract: A device to facilitate injection/extraction of fluids from cadaver's body cavities and to plug the incisions made to effect such injections/extractions. The trocar button of the present invention has both an external, manually operable drive surface and an internal drive surface engageable by a conventional insertion tool. Additionally, both the flange and the overall dimensions of the trocar button are increased to make it more user friendly.

Abstract: A sealing device for securing an oil plug in threaded engagement with the oil pan to prevent inadvertent loss of lubricating oil therefrom. The sealing device includes an elastomeric washer that underlies the bolt head of the oil plug, a partially closed-ended cylindrical sleeve that surrounds and is integral with the washer, and a cap that is interconnected to the sleeve by a membrane. The sleeve has a protruding lip extending about its upper periphery that interlocks with an abutment extending inwardly from an upper peripheral portion of the cap. Once engaged, the cap prevents the oil plug from being tampered with and from inadvertently dropping out.

Abstract: Fluid passageways are defined by the top plate, tool holder body and the cutting insert to permit the optimum cooling of the interface between the insert and the work piece reducing degradation of the cutting edge of the insert. A number of top plate designs with channel configurations are disclosed to provide the desired coolant flow distribution and accommodate the desired flow rate.

Abstract: Coolant delivery channels are cut into the external cylindrical side walls of a cutting tool to direct coolant into the cutting flutes of the tool. Coolant delivered through the chuck of a rotary power tool will be conveyed by the channels into the flutes adjacent the cutting edges to provide optimum cooling of the cutting zone.

Abstract: A compact package comprised of a collapsible seat and climbing aid for advantageous use with a tree stand. The climbing aid comprises a generally H-shaped frame with two hand grips projecting orthogonally out of plane of the frame. One rectangular housing is attached to each vertical upright member of the frame and locking screws engage portions of a supporting cable to adjust the size of loop for encircling an element to be climbed. A collapsible seat has an L-shaped frame sized to fit within the vertical uprights of the climbing aid and a securing nut positions a pivotable frame of the collapsible seat in either a first stored position or a second erect position. The securing nut also fastens the climbing aid to the tree stand when the seat is in the stored position.

Abstract: A blade guard and lifter therefor surround the saw blade, interlocking when raised by a workpiece as a result of relative movement caused by a secondary linkage. Two pair of primary linkages pivotally connect the blade guard to the splitter. The dual secondary linkage pivotally attaches the parallel plates of the lifter to one of the two pivot points of the primary linkages. Any lifting force is resisted by the rigidity of the primary link that does not share a pivot point with the secondary linkage. A dust collector can be provided to the table saw to minimize respiratory hazards.

Abstract: A transparent base panel has embedded therein a series of uniformly, sized, shaped and spaced louvers that extend outwardly from the base panel at an angle &bgr;, to optimize light flowing in a direction from an inner surface toward an outer surface while minimizing an amount of light flowing from the outer surface to the inner surface. This louvered screen has application in making outdoor illuminated signs more readable, in screening sunlight out of a compartment such as a room, and in deflecting and/or tinting light from a direct or indirect lighting source.

Abstract: Driving engagement is obtained between an arbor held in a machine tool and a collet holder that supports a drill bit by locking balls that are secured in engagement with drive surfaces by a locking ring. A nose cone is adjustably attached to the front of the locking ring and when the nose cone bottoms out on the workpiece, continued movement of the drill bit assembly relative to the nose cone assembly causes the locking ring to allow the locking balls to disengage the collet holder after ½″ additional travel. Inner and outer springs reposition the clutch mechanism in its initial position for subsequent drilling operations.

Abstract: A bow sight has a plurality of subassemblies adjustably attached to a main frame to permit vertical adjustment of the cross hairs. The subassemblies lie in different planes so that when the bow sight is used with a high powered, high speed bow, two or more of the cross hairs to be stacked or closely positioned, if necessary.

Abstract: An assembly including a power source, a device for attaching the power source to a lower portion of a fishing rod, a length of fiber optic cable with a plurality of clips for securing the cable to the rod, and a light bulb. The light bulb which may have utility in other applications, includes a configured mass of plastic which encloses a region of reduced density which defines a first reflective region while the exterior of the bulb defines a second reflective region. The light bulb has a recess which receives a second end of the fiber optic cable so that the cable conducts a light beam to the bulb where it engages the first reflective surface and is bounced between the first reflective surface and the second reflective surface. Preferably, an electrical shrink tubing forms a sleeve over the first few inches adjacent the power source to focus the light beam along the cable. Color may be added to the bulb for alternate decorative uses.

Abstract: A filtration system includes a magnetic drum for removing ferrous shavings and a dual canister filter unit equipped with replaceable filter bags. This palletized system may be plugged into most machine tools to filter the shavings-laden coolant to remove the metal shavings, tramp oil, sludge and dirt from liquid coolant to extend its useful life and minimize or eliminate down time.

Abstract: A frictional cord lock for use in locking one portion of a single length of cord relative to another. A first embodiment includes a cylindrical, barrel-shaped member having a cylindrical wall substantially surrounding a longitudinal axis, has a first cord end fixed in one opening in the cord lock. Second and third tear-drop shaped openings lie along a common axis that forms an angle with the longitudinal axis and receive a second portion of the cord, the first opening lying vertically between said the second and third openings. The cord slides freely in second and third openings when pulled along their common axis but locks when subjected to non-axial forces. The non-axial forces pull the cord into the v-shaped portion of the openings pinching the cord and securing them in place. A second embodiment employs a generally horizontal v-shaped channel to lock the cord in place.

Abstract: A protective cover made of absorbent, stretchable, high lubricity fabric for overlying cushioning frontal pads of helmets. The cover can absorb sweat and the high lubricity of the fabric will enable the helmet to be taken on and off numerous times without producing an abrasion on the wearer's skin.

Abstract: A process is described for separating particles based on differences in mass after the selective attachment of air bubbles to reduce the density of one or more of the components of the feed. A novel feature of this process is aeration of a hindered-bed of solids in a fluidized-bed separator to create particle/bubble agglomerates that can be separated based on the principal of gravity. This approach offers an improvement in process efficiency that cannot be achieved by other processes. Air and water are mixed in a shear device before the aerated fluidized water is introduced to the separation chamber.
