Abstract: Highly weather and corrosion resistant flexible reflective films for solar energy applications and lighting reflectors are formed by vapor-depositing silver onto a flexible support sheet, e.g., biaxially oriented polyester film and adherently bonding a protective fluorocarbon film, e.g., poly(vinyl fluoride), poly(vinylidine fluoride), or poly(tetrafluoroethylene), to the surface of the silver distal to the flexible support sheet with a layer of adhesive. Fluorocarbon film is highly optically transmissive to visible, ultraviolet, and/or near infra-red light between about 300-2,500 nanometers, stable to ultraviolet light, impervious to moisture, non-hygroscopic, scratch resistant, and easy to keep clean. The adhesive is highly optically transmissive to light between about 300-2,500 nanometers and stable to ultraviolet light. Chemical corrosion inhibitors and UV absorbers incorporated into the flexible reflective film can increase its resistance to corrosion and degradation by ultraviolet light.

Abstract: A leg exercising device including a frame, a pair of pedal arms pivotally secured to the frame, a double acting hydraulic cylinder having a chamber and a piston movably disposed therein, and a pair of valves connected to the hydraulic cylinder for controlling flow of fluid to and from the chamber on opposite sides of the piston. Foot engaging straps on the pedals exert a force in opposite directions toward and away from each pedal as a result of movement of the foot of a user in opposite directions. The valves are mounted adjacent the pedal within the reach of the user whose foot is in engagement with the foot engaging straps to permit independent adjustment of the magnitude of force resisting movement of the pedal arms in opposite directions.

Abstract: A method and apparatus for filtering a fluid through a particulate filter medium and for periodically scrubbing the particulate filter medium of accumulated contaminating material. During the filtration cycle, the particulate filter medium is retained with a filtration vessel by a bottom screen. During the scrubbing cycle, the particulate filter medium is retained within the filtration vessel by the bottom screen and a top screen. The combined surface area of the bottom screen and the top screen is substantially greater than the surface area of the bottom screen alone. During the scrubbing cycle, the particulate filter medium is fluidized with a scrubbing fluid and violently circulated to remove accumulated contaminating material from the filter medium, thereby suspending the contaminating material in the fluidized mixture.

Abstract: A method and apparatus to refrigerate air in a compartment wherein liquid CO2 is delivered through a first primary heat exchanger such that sufficient heat is absorbed to evaporate the liquid carbon dioxide to form pressurized vapor. The pressurized vapor is heated in a gas fired heater to prevent solidification of the pressurized carbon dioxide when it is depressurized to provide isentropic expansion of the vapor through pneumatically driven fan motors into a secondary heat exchanger. Orifices in inlets to the fan motors and solenoid valves in flow lines to the fan motors keep the vapor pressurized while the heater supplies sufficient heat to prevent solidification when the CO2 vapor expands through the motors. CO2 vapor is routed from the second heat exchanger to chill surface in a dehumidifer to condense moisture from a stream of air before it flows to the heat exchangers.

Abstract: A dampening fluid evaporator for a lithographic printing press incorporating a blower housing having an elongated inlet passage positioned to extend along substantially the entire length of a distributor roller. A transflow blower mounted in the blower housing draws air through the elongated intake passage along substantially the entire length of the roller while delivering a diffused stream of air which impinges against the roller for evaporating excess dampening fluid.

F. to finish baking the crust of the dough product, and to maintain the temperature of the crust greater than the temparature of the moist topping. The vented container is formed to exhaust moist air from the interior of the container while maintaining the temperature of air adjacent the moist topping on the dough product above the dewpoint of air in the container to prevent condensation of moisture and to draw air from outside the container to expel moisture from adjacent the bottom crust.

Abstract: A method and apparatus to refrigerate air in a compartment wherein liquid dioxide is delivered through a first primary heat exchanger such that sufficient heat is absorbed to evaporate the liquid carbon dioxide to form pressurized vapor. The pressurized vapor is heated in an external heat exchanger to prevent solidification of the pressurized carbon dioxide when it is depressurized to provide isentropic expansion of the vapor into a secondary heat exchanger. Pneumatically driven motors are driven by the pressurized carbon dioxide vapor to move air across the heat exchangers. Orifices in inlets to the motors and solenoid valves in flow lines to the motors keep the vapor pressurized while the external heat exchanger supplies sufficient heat to prevent solidification when it expands through the motors.
