Patent number: 5704104Abstract: A method and machine are disclosed for using a cold dry abrasion step for separating segments of discarded carpet into pile material (usually nylon) and backing layers (usually polypropylene) for recycling. A preferred method of abrasion uses dry ice pellets (made of frozen carbon dioxide) which are ejected at high speed from a set of nozzles that shoot the pellets directly into an abrasion zone, as a segment of discarded carpet on a conveyor system is being stripped apart and disassembled. The dry ice pellets "freeze" the binder material (usually latex) by lowering it to a temperature that makes the binder brittle and easy to break apart. The pellets also serve as abrasive agents, in a manner comparable to sand-blasting; however, unlike sandblasting or liquid (steam or chemical) systems, the dry ice pellets evaporate (sublimate) directly into gas without going through a liquid phase, and without leaving any liquid or gritty residue.Type: GrantFiled: December 27, 1995Date of Patent: January 6, 1998Inventors: Forrest C. Bacon, Wendell R. Holland, Lial H. Holland

Patent number: 5452582Abstract: In the cryo-probe, refrigerant is furnished from a high pressure, room temperature supply. Insulation of the refrigerant lines is unnecessary. Refrigerant flows through a pre-cooling heat exchanger in the probe and through a restrictor wherein the pressure drops. In accordance with the Joule-Thompson effect, the refrigerant expands and becomes cold and liquid is applied in the region of the cryo-tip to provide rapid cooling thereof. Expanded refrigerant gas at low pressure reverses direction and flows back from the cold tip in counterflow arrangement through the aforementioned heat exchanger to give a pre-cooling effect to the refrigerant incoming from the external supply. A second tube for conveying warm-up gas is located in the probe and extends to the cold tip. After cryosurgery is complete, the high pressure flow is stopped and warm gas is delivered to the tip in the probe at reduced pressure through the second tube from the same refrigerant supply as is used for cooling.Type: GrantFiled: July 6, 1994Date of Patent: September 26, 1995Assignee: APD Cryogenics, Inc.Inventor: Ralph C.

Patent number: 5079932Abstract: The invention describes a sorption self-cooling beverage device which cools its beverage instantaneously, and no heat conducting surfaces are required. A chamber containing a beverage is mixed with a consumable refrigerant such as water. The boiling point of the beverage-refrigerant mixture is lowered to freezing temperatures by an air vacuum. The vapor generated by the boiling beverage-refrigerant mixture is conducted to another chamber containing a desiccant, which removes the vapor. A barrier permeable to water vapor but not to desiccant particles is placed between the beverage-refrigerant and desiccant chambers to prevent a contamination of the beverage by the desiccant. A water absorber is placed in the desiccant chamber to prevent a contamination of the beverage with liquid which may have entered the desiccant chamber from the beverage chamber.Type: GrantFiled: January 30, 1991Date of Patent: January 14, 1992Inventor: Israel Siegel

Patent number: 5058396Abstract: A system for cooling comestibles is provided in multiple tiers of relatively shallow trays or receptacles vertically spaced apart at close intervals and mounted in a rack, in combination with one or more hollow wands containing refrigerant. Each wand is configured to have a longitudinally grooved immersible section which is insertible through narrow spaces between trays into material to be chilled. A reservoir for refrigerant extends from one end of the wand to the other. The wand can be periodically or continuously manipulated in twirling, revolving and translating motions which simultaneously mix the food and agitate the refrigerant so that the refrigerant circulates within the interior of the wand and quickly cools the food.Type: GrantFiled: February 20, 1991Date of Patent: October 22, 1991Assignee: Syracuse UniversityInventor: Norman A. Faiola

Patent number: 5042261Abstract: A histological tissue freezing process is provided. The process includes an aerosol can with an adjustable flow rate spray unit for spraying a chemical, monochlorodifluoromethane, onto a portion of a histological tissue specimen before sectioning thereof. The use of monochlorodifluoromethane has the dual advantage reducing ozone depletion and producing a colder spray. The spray means has a horizontal hinged spray bar with a passage with a spray outlet and has a horizontal hinged actuator plate with a trigger for slightly turning the actuator plate unit and spray bar. A tube has a passage connecting to the spray bar passage. The tube has an upper end coupled to the spray bar and an intermediate end extending through a can upper wall and a lower end disposed inside the can. The tube lower end has an adjustable orifice opening. The tube also has a latching unit, a compression spring, and seal ring.Type: GrantFiled: January 30, 1990Date of Patent: August 27, 1991Assignee: Cornwell CorporationInventors: James D. Yeakel, John H. Cornwell

Patent number: 4993236Abstract: A discrete internal self-cooling device (106) installed in a standard beverage can (100) during assembly. An evaporative cryogenic refrigerant vessel (112) has a cylinder vent hole (118) formed through it near its upper rim (120) adjacent to cylinder (126). An upper plug (122) sealing (112) has off-set inner (123) and outer (125) metering orifice segments formed in it axially. Intersecting these segments, an automatic pressure actuated release means comprises a transverse plug cylinder (126) containing a pressure actuated piston (131) carrying two axially rotatable rings (133) which form a circular piston channel (135) that opens or closes orifice segments (123) and (125) depending on its alignment with them. Alternative piston and rings configurations are provided. A means for thermally insulating vessel (112) from can (110) is provided by thermal transfer fin-spacers (110).Type: GrantFiled: April 6, 1990Date of Patent: February 19, 1991Inventor: John J. Wilson
