Title: CFC recycling system

Abstract

This patent describes a method for recycling freon. It comprises attaching a freon removal valve to a freon supply located in an appliance such as an air conditioner, refrigerator, freezer or the like, positioning a substantially empty freon collecting vessel in gas flow relationship to the valve by providing the freon removal valve with a puncture needle extending upwardly and adapted to puncture a freon supply tubing in the appliance, below the puncture needle is positioned a spring means, and below the spring means is positioned a piercing means adapted to pierce a closure in the collecting vessel to thereby establish a gas passage means extending from the supply tube, through the needle, through the piercing means to the collecting vessel, collecting the freon thereby in the collecting vessel, providing a substantially gas-free sealing means on the collecting vessel to insure substantial total containment of the freon within the collecting vessel, and delivering the collecting vessel to a collection center for reuse and recycling of the freon.

  • A fuel feeding system was designed comprising a carburetor having fuel passage between a fuel nozzle and a fuel bowl and including a sharp-edged orifice, together with means for controllably admitting air into the fuel passage means. ''Ends'' or ''drains'' are recycled from the crankcase through a sharp-edged orifice into an engine cylinder.
  • A heat exchange system is described for recycling waste heat leaving a building stack to supply heat to incoming fresh air or temper stored water of the building water storage system, wherein the building has a source of heat at constant temperature, such as a cooking facility, from which air conveying waste heat is drawn and impelled through a stack in which a closed circuit heat generated refrigerant flow type refrigeration system is established. The system includes a heat recovery coil in the stack, heat discharge coils in heat transfer relation to the incoming fresh air and the stored water,more » liquid refrigerant traps that permit free flow therethrough of the refrigerant adjacent the heat discharge coils adjacent their discharge ends, and thermostatically controlled valves for alternately disconnecting the heat discharge coils from the heat recovery coil in accordance with a predetermined ambient air temperature exteriorally of the building.« less
  • This patent describes a fuel cell recycling system comprising: first fuel cells being adapted to electrochemically convert fuel into electricity and exhaust; second fuel cells being adapted to electrochemically convert fuel into electricity and exhaust; feed means for supplying fuel to the first fuel cells in parallel; exhaust means for receiving exhaust from the first fuel cells; recycling means for directing a first portion of the exhaust of the first fuel cells from the exhaust means to the feed means to recycle the exhaust from the first fuel cells in the first fuel cells; vent means for directing a secondmore » portion of the exhaust from the exhaust means to the second fuel cells in parallel; and means for electrically connecting the first fuel cells and the second fuel cells in series such that the first fuel cells and the second fuel cells utilize equal proportions of the fuel.« less
  • A two-step resin recycling system and method solvent that produces essentially contaminant-free synthetic resin material. The system and method includes one or more solvent wash vessels to expose resin particles to a solvent, the solvent contacting the resin particles in the one or more solvent wash vessels to substantially remove contaminants on the resin particles. A separator is provided to separate the solvent from the resin particles after removal from the one or more solvent wash vessels. The resin particles are next exposed to carbon dioxide in a closed loop carbon dioxide system. The closed loop system includes a carbonmore » dioxide vessel where the carbon dioxide is exposed to the resin, substantially removing any residual solvent remaining on the resin particles after separation. A separation vessel is also provided to separate the solvent from the solvent laden carbon dioxide. Both the carbon dioxide and the solvent are reused after separation in the separation vessel.« less
  • A two step solvent and carbon dioxide based system that produces essentially contaminant-free synthetic resin material and which further includes a solvent cleaning system for periodically removing the contaminants from the solvent so that the solvent can be reused and the contaminants can be collected and safely discarded in an environmentally safe manner.
