Abstract: Enhanced methods, systems, and techniques for facilitating item exchange are provided. Example embodiments provide an Exchange Facilitator System (“EFS”), which facilitates listing and sale of items offered for sale by sellers via one or more third-party item exchange systems. In some embodiments, the EFS obtains information about an item offered for sale by a seller, and automatically generates a listing for the item, based on the information about the item and information about other items sold on one or more item exchange systems. The EFS may then electronically provide the generated item listing to an item exchange system, and further manage the progress and sale of the item via the item exchange system. This abstract is provided to comply with rules requiring an abstract, and is submitted with the intention that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: A heater assembly (20) for heating blow molding plastic preforms (14) includes a plurality of elongated heaters (26) mounted by a housing (24) and extending along a path of conveyance of the preforms in a parallel relationship to each other, and each heater includes an elongated parabolic reflector (44) that reflects radiation from an adjacent elongated bulb (36) to irradiate the conveyed preforms. The heater assembly (20) also includes a quartz window (58) located between the elongated heaters (26) and the conveyed preforms (14) to transmit infrared radiation while blocking longer wavelength radiation so as to provide uniform heating of the conveyed preforms.
