Abstract: A computer-implemented method is provided for managing retailer virtual stores for a plurality of retailers. Each of the retailer virtual stores displays products from one or more product providers available for sale to consumers. The method includes the steps of: receiving from each of the plurality of product providers data describing products available from the product provider; receiving from each of the plurality of product providers or representatives of the product providers an indication as to whether a retailer has permission to display a given product from the product provider; populating each of the retailer virtual stores with products selected by respective retailers and permitted to be displayed in the virtual store by product providers or representatives of the product providers; and periodically receiving from product providers changes to data on their products, and automatically updating product data in retailer virtual stores reflecting the changes.

Abstract: An improved procedure for cold start-up of closed loop boiler set and Cheng cycle system wherein the venting step, the boiler swelling problem and blowdown step of the conventional start-up are eliminated by use of an external pressure source to increase the operating pressure in the evaporator section which minimizes premature phase change and accompanying volume increase.
