Abstract: An oxygenation unit for insertion into a well is used to increase the oxygenation of ground water. The unit includes a length of tubing suspended in the well. Within the tubing are a plurality of parallel spaced plates. An electric potential is applied across adjacent plates such that electrolysis will break water down to oxygen and hydrogen. Water is circulated through the unit using an air flow draft pump in which air is bubbled up through an inverted funnel in the tube.

Abstract: A channel letter has a rear surface for mounting against a raceway, wall, or a structure for supporting the signage, and sheet metal sides defining the figuration of the letter of shape to be depicted. A lighting element is positioned against the rear surface of the enclosure, and a lens is retained to the open front of the enclosure. The lens is retained by a plurality of retainer clips to a shoulder recessed within the walls of the enclosure and a cable between opposing walls provides lateral support to the walls. Each of the retainer clips has a first and a second leg extending from a back with the legs spaced a distance sufficient for the legs to fit around the end of the sheet metal of the walls. A partially flexible finger extends from one of the legs into the space between the legs so a to wedge against a surface of the sheet metal wall and thereby retain the retainer clip to the wall.

Abstract: A tool body is cold formed by inserting a blank into a die which defines a portion of the outer surface of the tool body after which a punch applies an impact to the blank causing the outer surface of the blank to conform to the contour of the die. The completed tool has an elongate hub with a cylindrical forward portion having a diameter sized to rotatably fit within the bore of a tool holder and a rearward portion with a diameter a little less than the that of the forward portion. The smaller diameter rearward portion facilitates the insertion and alignment of the tool in the tool holder.

Abstract: An electric switch having a circuit breaker includes a manually operable actuator that moves one contact between a first and a second position. A bimetal member moves another contact between a first and a second position in response to an electric current above a given threshold passing therethrough, and the movement of this contact to the second position releases a catch that retains a spring loaded indicator in its retracted position. The two contacts abut one another closing the circuit when both contacts are in their first positions. An excessive current will therefore break the circuit and release the indicator to move to the extended position. The releasable catch resets after the bimetal member has cooled and it will again retain the indicator in the retracted position when it is subsequently manually depressed.

Abstract: A cutting tool has a centrally located tungsten carbide insert brazed into a seat at the forward end of the tool. The seat has a circular mouth and rearward of the mouth is a frustoconical inner wall. At the bottom of the seat is a transverse surface. A tungsten carbide insert is brazed into the seat and the base of the insert is complementary in shape to the seat. A second annular insert may also be brazed into a complementary shaped annular seat that surrounds the centrally located seat.

Abstract: A fueling crane comprises an extensible boom rotatably associated with a pedestal wherein the extensible boom has a first end rotatably affixed to a fuel inlet pipe mounted on the pedestal and a second end terminating in a fueling nozzle. The extensible boom has at least one elbow joint between the first end and the second end wherein the elbow joint permits the fueling crane to provide fuel to any vehicle spaced from the pedestal within a given radius. The extensible boom is generally disposed in an upright manner wherein the elbow joint is spaced horizontally from but substantially directly above the pedestal and the second end is substantially adjacent the first end when the extensible boom is in a storage position. The improved extensible boom has means for returning the fueling nozzle to the storage position with the fueling nozzle disposed directly over a fuel drip collector thus providing for an environmentally secure fueling station.

Abstract: An inline sampling device adapted to remove a representative sample drop-wise from a fluid flowing through a fluid line through a sampling probe disposed in the fluid line wherein the sampling probe has at least one fluid receiving, volume relief port adapted for receiving a multiplicity of drop-wise samples of fluid flowing through the fluid line and for discharging a portion of the volume of a sampling container. The device is particularly suitable for testing for mastitis in milking animals.

Abstract: A valve assembly includes a valve housing defining a metering chamber and an elongated stem. The stem is axially movable with respect to the valve housing for dispensing liquid and is rotatable for adjusting the length of the stroke of a piston to thereby select the volume of liquid dispensed with each actuation of the stem. A sliding float member is fitted around the stem within the chamber and is axially slidable with respect to the stem but is locked for rotation with the stem. The lower surface of the sliding float abuts, and floats above the upper surface of the piston, and the lower end of the stem is rotatable within the piston. A spring extends between a prong on the stem and the sliding float for urging the stem axially outward of the container and for urging the piston in a direction which maximizes the volume of the metering chamber such that the spring rotates with the stem and the stem rotates free of the piston.

Abstract: A transparent flexible shield is provided to protect the outer portions of the cornea and the under surface of a cap of the cornea during LASIK surgery comprising a transparent annular body with a central opening. The central opening is sized to be a little smaller than the outer diameter of the cut made to form the cap. The shield is positioned on the upper surface of the cornea and the folded cap to protect the outer edges thereof from exposure to the ray of the laser.

Abstract: An integrated medicament package comprises a prefabricated medicament container having a plurality of initially open top blisters, a closure cover affixed to one marginal edge thereof by at least one living hinge, the closure cover having at least one clasp on an open end of the closure cover opposite the living hinge, the blisters arranged in rows and columns separated by longitudinal and transverse shoulders, at least one of the longitudinal and the transverse shoulders having perforations therethrough wherein the prefabricated medicine container is adapted to be separated along the perforations into a plurality of units, and a sealing sheet with medicament information at a location corresponding to the at least one said plurality of blister such that the medicament information on the outside surface of the sealing sheet corresponds with the medicament in the blisters, the medicament information comprising the name of the patient, the name of the medicament, the dosage of the medicament, the time of day, th

Abstract: To retain a decorative tubular cover having a given inner diameter over the axle hub of a wheel, a strap having a plurality of radially extending arms thereon is tightened around the circumference of the axle hub. The ends of the arms define a circle having a diameter a little larger than the given inner diameter of the tubular cover. The tubular cover is pushed over the arms until the open end thereof rests against the web of the wheel where it is retained by the outwardly directed forces applied by the arms.
