Abstract: A method of producing a gypsum binder, the method including dehydrating of gypsum raw material lumps by heating in a gaseous medium with further drying, cooling, and milling stages, wherein the heating gypsum raw material lumps is performed either by: (i) placing the lumps in a heating medium set to a temperature exceeding the temperature under which dehydration and formation of gypsum ?-hemihydrate occurs; and/or (ii) placing the lumps in a heating medium having a high rate of temperature increase such that a temperature higher than the temperature under which dehydration and formation of gypsum ?-hemihydrate occurs is reached; wherein a heating time is selected sufficient for completion of the process of gypsum ?-modification formation within the gypsum lumps, and wherein the heating is performed under atmospheric pressure through lump surface.

Abstract: The invention provides a method for customizing consumer product packaged thereby. The purpose of this method is to attract, increase, or retain consumer interest by varying the images appearing on packages of the products which appear to the consumer is different in most of time. The method involves selecting a number of packages the consumer will purchase without seeing the same image repeated. A group of images is randomly selected to the products such as individual packages, the consumer packages, and the cartons of consumer packages, and one image is randomly placed on each package. The method further varies the images by changing them based upon, the consumer purchasing characteristics statistically after a selected time period.

Abstract: The invention provides a method for packaging homogenous products and the products packaged thereby. The method varies the images appearing on packages of the products to attract, increase, or retain consumer interest. The method's object is to make it statistically likely to a degree acceptable to the user that the images on the product package seen by the consumer are different. The method involves selecting a number of packages the consumer will purchase without seeing the same image repeated. The number can be selected by any appropriate technique. A group of images is selected appropriate to the product involved, and one image is placed on each package. The method can be used simultaneously on the individual packages, the consumer packages, and the cartons of consumer packages. The method further varies the images by periodically changing them based upon the consumer purchasing characteristics and by using statistical and probability tools.
