Abstract: A method of buyer-seller interaction wherein multiple sellers agree to coordinate their individual sales in a coordinated sale is disclosed using a internet-based service. The individual sales within a coordinated sale are scheduled to start in succession. Sellers log onto a website interface for the service, and create a profile, including a listing of featured items for sale. A forum is available on the website where sellers may interact with each other to agree to establish a coordinated sale. The individual sellers desiring to participate in the coordinated sale coordinate the start times of the individual sales. Buyers may access the website to view the coordinated sale announcements, and view location, times and items for sale.

Abstract: A system for cleaning cone/shake makers in place. Cone/shake makers have at least one freezer for making ice cream cones or milk shakes. Each freezer has a product inlet, a product pump for pumping product from the inlet into the freezer, and at least one draw valve for dispensing the product in the freezer. The cleaning system has a mixing tank for mixing water with a cleansing chemical, the mixing tank having a capacity of less than one-fourth the volume of the water and cleansing chemical mixture to be used while cleaning a cone/shake maker. The system controllably provides the cleansing chemical to the mixing tank at a rate corresponding to the rate at which water flow into the mixing tank, thereby making a cleansing chemical solution of predefined concentration on the fly as the mixture is being used to clean the cone/shake maker.
