Abstract: A syringe includes a retractable needle assembly comprising a needle seat, a hypodermic needle, and a barrel. A hollow plunger is slidably mounted within the barrel. A seal is provided between the plunger and barrel to prevent air from passing into or out of the barrel. A piston is slidably mounted within the plunger such that movement of the plunger into the fill position locks the piston in place. A seal between the piston and the interior of the plunger prevents air or fluid from passing into the plunger. As the plunger is depressed the plunger moves in the barrel while in the piston is stationary. The relative axial movement of the plunger in relation to the piston causes a vacuum to be created within the plunger. The plunger in the fully depressed position releases the needle carrier and the vacuum pulls the needle carrier and needle into the hollow plunger.

Abstract: An IV container spike and drip chamber assembly is provided that includes an automatic shut off mechanism which allows nurses to change the fluid container without removing the catheter from the patient. The automatic shut off mechanism comprises a floating ball capable of being supported by or floating in the fluid due to the buoyancy of the fluid. The IV container spike also includes an air vent which allows the air in the drip chamber to vent out directly when the nurses want to change the container of medicinal fluid. The air vent is closed for the initial use and during the infusion process. As the medicinal fluid is gradually reduced in level in the drip chamber, the floating ball is lowered thereby and when the floating ball reaches the bottom of the drip chamber, the floating ball blocks the outlet so as to stop the injection.

Abstract: A dispenser for tableted chemical treatment material into an air conditioner condensate pan drain line comprises a container for the tablets and a removable cover sealed to the container by a gasket.

Abstract: An environmentally accommodating, reduced NOx, spark or plasma ignited, reciprocating, multi-fuel engine utilizing direct, in-cylinder water injection and an optional oxygen enriched air supply is able to operate as an ultra-lean burn, high compression ratio engine for notable power output and increased efficiency. The in-cylinder low-temperature water injection promotes numerous desirable effects. One, the in-cylinder water injection during compression stroke significantly lowers compression temperatures through the latent heat of vaporization of the liquid water to the gaseous form. The lower temperature of compression permits increased compression ratios while avoiding pre-ignition. As well, the low-temperature water injected air/fuel or enriched O.sub.2 /air/fuel mass demands less work in the compression stroke thereby increasing overall engine efficiency. The low-temperature water injection promotes increased mass flow through the engine for increased power output and efficiency.
