Abstract: The invention comprises the use of bacterially generated polymers as coagulants and flocculents for the removal of suspended solids from wastewater. Polymer producing bacteria such as Bacillus polymyxa NRRL 21881 are added to wastewater treatment systems. The bacteria will reproduce in the system, substantially increasing the number of coagulants over the amount of original bacteria introduced. Throughout their life cycles, the bacteria will biologically treat BOD.sub.5 in the system. When the BOD.sub.5 levels are sufficiently low, the bacteria will produce polymers to increase their ability to capture organic matter. The polymers will capture the suspended particles in the water, creating strands of polymer connected particles. As the strands come into contact with one another, the strands will become entwined, creating flocs. These flocs will combine and will absorb the suspended particles which they encounter.

The support arms have opposing notches sized to receive a can handle attachment members and where the notches are positioned to permit the can to pivot about the can handle attachment members; and a belt suspension member attachable to one end to a belt and pivotally attachable at its end opposite the back plate.

Abstract: The invention comprises a needle aspiration safety syringe having a barrel, a plunger, a retractable needle, and a delayed engagement mechanism. The needle is functionally connected to the plunger by the delayed engagement mechanism such that when the plunger is retracted from an initial extended position, the needle does not retract immediately. The needle provides passage into the fluid receiving cavity, such that retraction of the plunger causes tissue fluid to flow from a target tissue through the needle and into the fluid receiving cavity. Further retraction of the plunger causes the delayed engagement mechanism to engage, whereupon the needle can be withdrawn completely into the fluid receiving cavity, such that the sharp end of the needle is no longer exposed. After the needle withdraws completely into the fluid receiving cavity, the needle cannot exit the fluid receiving cavity, such that the sharp end of the needle poses no danger of sticking a user or patient.

Abstract: A submersible work vessel and a method of using the same are disclosed. The vessel contains an internal work space. It also contains a set of openable jaws that are designed to engage an underwater pipe. When the pipe is engaged, it will pass through the internal work space of the submersible work vessel. When the jaws have engaged the pipe, the internal work space should be substantially watertight, at which point the water in internal work space may be pumped out. When the water has been substantially evacuated, a worker may enter the internal work space and work on the pipe. One of the principal tasks the work vessel is designed to facilitate is the installation of a blow out preventer. The worker will install the blow out preventer on the pipe. The blow out preventer is designed to remove a section of the pipe and then to seal the severed pipe. This is preferably done with a cutter mounted on a hydraulic arm and a sealing block also mounted on a hydraulic arm.

Abstract: A device to assist in removing a fetus from a woman's birth canal during childbirth is provided. The device includes a pliable, elongated member having a mouth adapted to fit over the head of a fetus, an insertion wand or applicator for positioning the elongated member over the head of the fetus, and a drawstring attached at the mouth. The elongated member is constructed so that as it is pulled longitudinally from the end opposite the mouth, the elongated member will axially grip the head of the fetus in much the same way that the novelty item, "Chinese handcuffs," grip the finger of a user. Once the elongated member has axially engaged the head of the fetus, the elongated member may be used to extract the fetus from the birth canal.

Abstract: A clip for supporting the clarifier and the droplines in a wastewater treatment system is disclosed. The clip comprises a pair of parallel main plates separated by a bracing plate. The bracing plate is perpendicular to the main plates and is attached to the ends of each. Attached to the free ends of each of the main plates are a pair of mounting plates. These mounting plates are parallel to the bracing plate. In a preferred embodiment, the main plates each contain a hole. This pair of holes are vertically aligned, and each hole is sized to contain a dropline.

Abstract: A method for simultaneously clarifying lesions on poultry paws and for blanching or whitening poultry paws is disclosed. The paws are steamed for about fifteen seconds. Next they are soaked in an aqueous solution of hydrogen peroxide for about twenty minutes. The hydrogen peroxide preferably comprises about 2.0% of the solution by volume and the solution preferably has a pH of between about 9.6 and about 10.6. The solution should also preferably contain about 100 ppm of a food grade surfactant suitable for dissolving oils into water. An anti-foam agent may also be included in the solution. After soaking, the skin of the paws is preferably removed, most preferably by subjecting the paws to rotating rubber fingers. When the process is complete, the paws are substantially white, and any lesions that may have been present are substantially clear. Additionally, the process will cause the paws to absorb water which will make them heavier.

Abstract: A device for locking movable objects, such as all terrain vehicles, in place. The device comprises an anchor member engageable with an embracing member where the embracing member embraces the object to be locked in place and engages the anchor member. The embracing member is locked with the anchor member with a lock. The anchor member can be inserted into the ground or fixedly attached to an immovable object thereby securing the invention in place.

Abstract: A glo-plug extractor is disclosed. An internally threaded sleeve is threaded over an externally threaded bolt having a bolt head at one end and a set of jaws at the other. The jaws are fitted to lock onto the head of a fully unscrewed, yet bound glo-plug. After the jaws are locked onto the glo-plug, the sleeve is braced against the engine head either by screwing the sleeve down over the jaws until it contacts the engine head or by placing some bracing apparatus such as a spacer or a set of legs between the sleeve and the engine head. Once the sleeve is braced, it must be locked in place using a locking apparatus such as vice grips or a wrench. The bolt head is then used to rotate the bolt relative to the sleeve. This rotation causes the sleeve to exert a pulling force on the bound glo-plug which either extracts the glo-plug whole or breaks it.

Abstract: A wastewater treatment system: The system entails an aerobic tank and an anaerobic tank. Wastewater enters the aerobic tank where it is aerobically treated. The effluent then flows to the anaerobic tank where it is anaerobically treated to remove nitrogen in the wastewater. A filter may be added to the discharge line from the anaerobic tank to remove any suspended solids emitted with the effluent from the anaerobic tank.

Abstract: A safety syringe is disclosed and claimed. The safety syringe has a hollow barrel and a plunger. The plunger enters the barrel from one end and a needle leaves the barrel from the other end. A thin blunt sheath is positioned over the needle. The sheath has an exposed position in which the point of the needle is exposed and a covered position in which the point of the needle is covered. A connector functionally joins the sheath to the plunger so that the sheath is advanced from the exposed position to the covered position as the plunger is advanced. In operation, the safety syringe is filled like a conventional syringe by placing the needle in a vial of medication and drawing back on the plunger. Once the safety syringe is filled, the needle is inserted into the patient. The needle should be inserted a sufficient distance to insert the end of the sheath into the patient as well. The medication is then injected into the patient by depressing the plunger.
