Further, the present invention includes a process for analyzing a test medium which includes scattering multiple adsorber devices throughout the test medium; recovering the devices after a predetermined amount of time; and leaching the accumulated solutes from the adsorber material to provide an extract solution which can then be analyzed by various procedures to determine quantities of accumulated solutes.

Abstract: The present invention relates to a disposable medical syringe which has a hollow plunger to receive a used inoculation needle. The syringe has a hollow syringe barrel, open on one end and closed on the other. A hollow plunger assembly, which extends out the open end of the syringe barrel, has a hollow tube with a fixed seal attached at one end. At the other end of the plunger assembly, a needle holder is sized to slide within the hollow tube. The sliding seal and needle holder are biased toward each other by a stretched, resilient tube that has a fluid passageway passing through the sliding seal, resilient tube, and needle holder. The needle holder is normally locked at one end of the plunger assembly by a locking means. As the syringe is collapsed, the syringe barrel trips the locking means to permit the needle holder, and attached inoculation needle, to be retracted into the hollow tube.

Abstract: The present invention relates to an improved fishing device which provides a shock absorbing device between a fishing line and a fishing hook. An elongate member formed from certain knitted materials can "remember" a twist. This characteristic is used to have a twisted, elongate member "untwist" about its longitudinal axis as it is stretched. Then the elongate member will retwist tightly as the strain is reduced between opposite ends of the twisted member. The motion is both parallel to and rotational about the longitudinal axis of the elongate member. The resilient member is also made with a soft cloth-like material so that a line will not normally be inadvertently intertwined with the device.

Abstract: The harness comprises a carrying strap and a gripper. The carrying strap is formed from a soft material. Another strap formed from a stronger, less resilient fabric is attached to the soft strap at uniformly spaced intervals and in such a way that the second strap forms loops at its points of attachment to the soft strap. With the arrangement, the soft strap can only stretch until the loops become taut. Thereafter, the stronger second strap carries the load and this prevents the soft strap from tearing when heavy loads are carried. The gripper is formed from a resilient material and comprises a first plate and a second plate which are connected together by an arcuate web. One of the plates of the gripper has a flat body contacting surface and a loop is positioned in the arcuate web between the first and second plates for connection to a device to be carried. A plurality of pins are formed on at least one plate of the gripper.

Abstract: An improved tissue container having a dispenser compartment and disposal compartment. The container has a tissue dispensing opening in the dispensing compartment and a tissue receiving opening in the disposal compartment through which soiled tissue may be inserted. The two compartments are formed on opposite sides of a flexible, bag-like liner with the liner opening only at the soiled tissue receiving opening. The bag-like liner prevents contaminants from contaminating the clean tissue compartment. The liner is arranged so that a load of clean tissues in the clean tissue compartment provides supporting structure to keep the liner from snarling and restricting the available space in the disposal compartment.

Abstract: A pouring spout assembly removeably fitted inside the mouth of a supply container includes an elongate spout for pouring liquid from the supply container to the target container through a spout exit opening. This spout further includes a tubular vent extending from the interior of the supply container to a vent opening adjacent the spout exit opening. A cap is threaded on to the mouth of the supply container and provides an air tight seal between the inside of the supply container to the atmosphere. A valve is provided, which valve is resiliently biased to a normally closed position to prevent fluid flow through the spout and to prevent air from being drawn through the vent. Structure is provided so that a user may manually open the valve by the act of inserting the spout into the target container.

Abstract: A guide ring for a broadhead encircles an arrow shaft and is frictionally held at the tail edges of the broadhead's blades. The guide ring has a smaller inside diameter at its rearward edge than at its forward edge to deflect air inwardly toward the arrow shaft. The smaller inside diameter is also sized to be larger than the arrow shaft which it encircles to provide space for air to flow between the guide ring and the shaft. Notches on the forward edge of the guide ring frictionally grip the tail edges of the broadhead blades to hold the guide ring in position during the flight of an arrow. When the arrow is in flight, the shape of the guide ring smoothly directs air toward the arrow shaft to increase the airflow past the arrow fletching for increased stability of the arrow. When the broadhead penetrates a target deeper than the tail edge of the blades, the guide ring is forced rearward away from the blades by the target material contacting the forward edge of the guide ring.

Abstract: A battery-powered pacemaker includes an electrical pulse generating device enclosed in a portable case. The pulse generating device is connected to a disposable electrode insertion unit that can easily be inserted in a patient's heart. A relatively short conductive lead connects the pulse generating device and the electrode insertion unit. The case of this pacemaker can be placed on the patient or near the side of the patient but out of the way, thus eliminating the use of the long conductive leads which has been a problem in the past. The present pacemaker also used a male connector on the case to receive a female connector attached to the conductive lead. The male/female connector is used so that blood and other contaminants can be easily cleaned from the male fitting before the unit is reused. Barbless hooks attached to one side of the electrrode insertion unit are used for electrically connecting the pulse generating means device to the heart.

A trigger mechanism is provided to release the cocked rod holder so that the rod holder may swing upwardly to the normal, generally vertical, position to hook the fish. An adjustable connecting means is provided for connecting the coil spring to the base. The coil spring may be adjusted to control the force acting to rotate the fishing rod upwardly, and to control the force required to release the trigger.

Abstract: A fly-fishing strike indicator which is moveable on a fishing leader but at the same time can maintain its position on the leader when a fly is cast. The indicator is constructed by forming a knot of surgical tubing on the leader. The knot being formed by passing one end of a leader through the center passage of a small section of surgical tubing and looping the leader outside the tubing and then reinserting the leader through the center passage of the tube in the same direction as before. As the leader is pulled taut, the resilient tube is deformed into a knot wherein the leaders runs nearly straight through the knot. Further, a cover of thermoplastic, heat shrinkable tubing is slid over the knot to surround the leader and the knot. The ends of the thermoplastic cover are then heated to constrict the ends loosely about the leader and to form an air pocket between the leader and cover.
