  • Patent number: 6510890
    Abstract: An apparatus for making a frozen food product comprising a mixer having no moving parts is disclosed. The apparatus further comprises heating means external to the mixer. The premix and refrigerant combine inside the mixer to produce a frozen food product. The heating of the mixer raises the temperature of the mixer sufficiently to prevent crystallization of the mixer contents at the mixer wall, thus preventing “over-freezing.” In this way, plugging of the mixer is minimized and the end product exits the mixer unassisted by mechanical means, yet is still in a frozen state. Thus, it is now possible to produce a quality frozen food product using cryogenic refrigerants, without causing the end product to be at cryogenic temperatures. The present invention has the further advantage of allowing adjustable quantities of refrigerant and premix to be used. The invention is simple in operation and can be operated in a portable and/or continuous manner.

  • Publication number: 20010037266
    Abstract: A UPC image server system includes at least one image file server, high-speed Internet access, and a plurality of images stored on the image file server. The plurality of image files are stored on the mass storage system of at least one image file server according to their UPC numbers and image size. The images are accessible by entering the domain of the image file server, the UPC number of the product, and the desired image size, all in a standardized format (a unique URL). The unique URL of the image on the image file server is written into the web page code or generated by software as required. When a customer desires to access an e-commerce web page, only the web page and proprietary images are sent from the e-commerce server. The consumer product images are downloaded from the UPC image file server system.
